The 'Great Southern Reef': social, ecological and economic value of Australia's neglected kelp forests 
Scott Bennett, Thomas Wernberg, Sean D. Connell, Alistair J. Hobday, Craig R. Johnson and Elvira S. Poloczanska

Most Australians live near kelp forests, yet have little awareness of their value and significance. The ‘Great Southern Reef’ covers ~71 000 km2 along Australia’s temperate coastline. Its kelp forests boast unique marine life from at least nine phyla and it contributes at least AU$10 billion year–1 to Australia’s economy. The GSR is a significant natural asset that deserves recognition and investment.

A comparison of the physiological responses, behaviour and biotransformation of paralytic shellfish poisoning toxins in a surf-clam (Paphies donacina) and the green-lipped mussel (Perna canaliculus) 
Islay D. Marsden, Andrea M. Contreras, Lincoln MacKenzie and Murray H.G. Munro

Paralytic shellfish poisoning (PSP) occurs when people consume shellfish containing algal toxins known as saxitoxins. Both surf clams and green-lipped mussels readily accumulate these toxins. After 8 days of detoxification, toxin concentrations in the mussels had fallen, but in the clams, concentrations remained higher than was safe for human consumption. Mussels and clams can therefore be used to monitor the health risks associated with toxic algal blooms.

Patterns of shelter use and their effects on the relative survival of subadult California spiny lobster (Panulirus interruptus) 
Amalia M. Harrington and Kevin A. Hovel

The California spiny lobster is an ecologically and economically important species on southern California rocky reefs. We used manipulative experiments to determine how sheltering behaviors observed on naturally-occurring reefs influence the survival of subadult lobsters. Our study is the first to demonstrate the survival benefit of selecting shelters based on the size, and not just the presence, of other lobsters.

Reproductive pattern and sexual system of the nocturnal seagrass shrimp Ambidexter symmetricus (Decapoda: Caridea: Processidae) in a Florida bay 
Jennifer A. Rasch and Raymond T. Bauer

The goal of our research was to analyse the reproductive ecology and sexual system in a nocturnal seagrass shrimp. We found sex ratios support a gonochoric sexual system, seasonal breeding with successive spawns, sexual dimorphism and that the interaction of time of year, shrimp sex and parasite presence influenced shrimp size. This data support hypotheses about latitudinal trends in other marine species.

Identification of human-made physical barriers to fish passage in the Wet Tropics region, Australia 
Frederieke J. Kroon and Seonaid Phillips

Physical barriers in streams and rivers can deny fish access to habitat and food beyond these structures. This study identified a total of 3748 bridges, culverts and causeways in Australia’s Wet Tropics region that could potentially be barriers to fish passage. This inventory provides a first step in the prioritisation of potential barriers for removal and remediation to improve native fish movement and fisheries production

Biology of a marine estuarine-opportunist fish species in a microtidal estuary, including comparisons among decades and with coastal waters 
Lauren J. Veale, Peter G. Coulson, Norman G. Hall and Ian C. Potter

This study explored the benefits to a marine fish species of using both estuaries and nearshore coastal waters as nursery habitats. The abundance, growth and reproductive status of Pelates octolineatus in a large estuary are thus compared with those in marine waters. Many individuals use the estuary for an extended period and grow faster there than in coastal marine waters.

The contribution of migratory mesopelagic fishes to neuston fish assemblages across the Atlantic, Indian and Pacific Oceans 
M. Pilar Olivar, J. Ignacio González-Gordillo, Jordi Salat, Guillem Chust, Andrés Cózar, Santiago Hernández-León, M. Luz Fernández de Puelles and Xabier Irigoien

The neuston is a rich environment inhabited by a large variety of species. Some myctophids (mesopelagic fishes) reach this layer during their night feeding migrations, constituting an important resource competitor for the neustonic-dwelling species. Surface temperature is the main environmental variable shaping the distribution of neustonic species, whereas myctophids are also influenced by the minimum oxygen concentrations in the water column.

Determining optimal sampling strategies for monitoring threatened endemic macro-invertebrates in Australia 
R. A. Rossini, R. J. Fensham and G. H. Walter

Australian artesian springs are hot spots for aquatic diversity but data deficiency hinders conservation efforts. This study compared existing study methods for sampling the diversity and abundance of macro-invertebrates in springs and found that diversity can be sampled rapidly and with little bias, yet abundance measures are sensitive to method. This means we can pool existing disparate data sources pertaining to diversity at a national scale, and offer an optimised strategy for all taxa encountered.

Looking backwards to look forwards: the role of natural history in temperate reef ecology 
S. J. Hawkins, N. Mieszkowska, L. B. Firth, K. Bohn, M. T. Burrows, M. A. MacLean, R. C. Thompson, B. K. K. Chan, C. Little and G. A. Williams

Temperate reefs are tractable experimental systems that have made a major contribution to general ecological and evolutionary biology. We celebrate this rich heritage firmly based in natural history. Knowledge of natural history us central to this contribution in terms of formulating appropriate questions, ensuring appropriate stratification of surveys and experiments. Natural history feeds into more modern modelling, macro-ecological and meta-analytical approaches where trait-based approaches are increasingly important. In the era of molecular bar-coding natural history is still needed to put a name to species enabling field identification. Thus going forward temperate reef ecologists most embrace new technologies and approaches whilst retaining classical skills to remain well-rounded ecologists.

Spatio-temporal variability of the surf-zone fauna of two Ecuadorian sandy beaches 
Jose R. Marin Jarrin, Sandra L. Miño Quezada, Luis E. Dominguez-Granda, Sonnia M. Guartatanga Argudo and Maria del Pilar Cornejó R. de Grunauer

Sandy beaches and their surf-zones are the most common coastal habitat and are inhabited by diverse fauna, including economically important species. The present study described the small swimming-area fauna of two Ecuadorian sandy beaches and found that their communities varied most strongly between beaches, and less so between seasons, potentially due to the influence of adjacent rivers and oceanic currents. Our results suggest that despite the environmental stability often portrayed for tropical environments, Ecuadorian surf-zone fauna are spatially and temporally variable.

Demersal chondrichthyans in the western Mediterranean: assemblages and biological parameters of their main species 
Sergio Ramírez-Amaro, Francesc Ordines, Bàrbara Terrasa, Antonio Esteban, Cristina García, Beatriz Guijarro and Enric Massutí

Demersal chondrichthyan assemblages were compared in four geographical subareas established by the General Fisheries Commission for the Mediterranean in the western Mediterranean. Present study revealed two assemblages related to depth, with similar bathymetric ranges in all subareas, namely continental shelf and slope. However diversity, abundance and biomass values were different between subareas which reflects the effects of the distinct fishing and oceanographic parameters.

A commentary on 'Long-term ecological trends of flow-dependent ecosystems in a major regulated river basin', by Matthew J. Colloff, Peter Caley, Neil Saintilan, Carmel A. Pollino and Neville D. Crossman 
Richard T. Kingsford, Ralph Mac Nally, Alison King, Keith F. Walker, Gilad Bino, Ross Thompson, Skye Wassens and Paul Humphries

Colloff et al. in Marine and Freshwater Research (http://dx.doi.org/10.1071/MF14067) analysed 301 biological datasets for the Murray–Darling Basin, concluding that the overwhelming pattern was one of fluctuating stability, irretrievably affected by changes in land use. We provide evidence that their conclusions are inadequately supported, and multiple factors, particularly water resource development, continue to degrade freshwater ecosystems, requiring restoration of flows.

Feeding dynamics of the fiddler crab (Uca annulipes) in a non-tidal mangrove forest 
N. Peer, N. A. F. Miranda, R. Perissinotto and J. L. Raw

Lack of tidal influence in estuarine habitats is predicted to increase globally but we do not yet understand the associated ecological consequences. Gut chlorophyll levels of a fiddler crab showed that feeding dynamics vary with season, time of day and between sexes in a non-tidal mangrove habitat. These results provide insight into the response of macrobenthos to environmental change.

Olfactory responses of coral-reef fishes to coral degradation and crown-of-thorns (Acanthaster planci) 
Amy G. Coppock, Naomi M. Gardiner and Geoffrey P. Jones

Coral degradation is a major threat toward coral-reef ecosystems, a factor that is likely to be problematic for species that exhibit specific habitat preferences. The ability of juvenile coral reef fishes to identify poor habitats, namely degraded coral and the presence of crown-of-thorns starfish, through smell was investigated. Whereas the crown-of-thorns elicited a limited response (unless feeding), the smell of degraded coral was actively avoided, such reactions are important for predicting ecosystem alterations resulting from environmental change.

Reproduction of French angelfish Pomacanthus paru (Teleostei: Pomacanthidae) and implications for management of the ornamental fish trade in Brazil 
Caroline Vieira Feitosa, Simone Marques, Maria Elisabeth de Araújo and Beatrice Padovani Ferreira

Pomacanthus paru is one of the most exported species in the Brazilian aquarium trade and is caught by traps as bycatch. This species was gonochoristic, exhibited size dimorphism and the size at maturity of females was 23.30 cm. At the spawning stage, females may be more vulnerable to trap fishing. Management measures should consider implementing trap-free areas in spawning grounds.

Influence of oceanic fronts on mesozooplankton abundance and grazing during spring in the south-western Atlantic 
Rubens M. Lopes, Catarina R. Marcolin and Frederico P. Brandini

Oceanic fronts are often considered as sites of enhanced biological production, influencing fish stocks and the global carbon cycle. We evaluated zooplankton biomass and grazing across a latitudinal gradient in the South-west Atlantic Ocean, and found that subtropical and subpolar frontal areas have higher zooplankton activity than surrounding waters. Our results suggest that these frontal systems have a significant effect on zooplankton, ultimately affecting deep-water carbon sequestration.

Comparison of in situ and satellite sea surface-temperature data from South Australia and Tasmania: how reliable are satellite data as a proxy for coastal temperatures in temperate southern Australia? 
B. Stobart, S. Mayfield, C. Mundy, A. J. Hobday and J. R. Hartog

Studies of marine life increasingly use sea-surface temperature from satellites assuming it represents conditions in the water column, yet this assumption has rarely been tested. We compared satellite and water column temperatures spanning a wide geographic range across southern Australia and found they were generally similar, but can differ considerably depending on local conditions. Therefore, although satellite temperatures should be adequate for many broad-scale studies, they should be validated prior to using in finer-scale studies.

Population dynamics of a high-latitude coral Alveopora japonica Eguchi from Jeju Island, off the southern coast of Korea 
Christophe Vieira, Shashank Keshavmurthy, Se-Jong Ju, Kiseong Hyeong, Inah Seo, Chang-Keun Kang, Hyun-Ki Hong, Chaolun Allen Chen and Kwang-Sik Choi

The coral Alveopora japonica in Jeju Island, South Korea, has increased in number over past decades and has encroached upon the macroalgal substrates affecting both the presence of macroalgae and abalone populations, which feed on macroalgae. To assess the dynamics the population increase, population-ecology studies of this coral was conducted from two locations at north and south of the Island. Population-age and -size structures at both sites reflected a healthy status and indicated a local stability, with a stationary size structure allowing population maintenance over time. The present study provided data to develop population-dynamics models to predict the potential outcomes of A. japonica populations to alternative management scenarios in Jeju Island.

Morphologically similar, coexisting hard corals (Porites lobata and P. solida) display similar trophic isotopic ratios across reefs and depths 
Jeremiah G. Plass-Johnson, Christopher D. McQuaid and Jaclyn M. Hill

Few studies have accounted for morphology when comparing interspecific differences in the isotopic values of corals. In this study we show that the δ13C and δ15N values of Porites lobata and P. solida have few differences across reefs and depths. This suggests that resource partitioning among corals is mostly driven by resource acquisition, rather than being inherently species-specific.

A Ramsar-wetland in suburbia: wetland management in an urbanised, industrialised area 
S. J. Kermode, H. Heijnis, H. Wong, A. Zawadzki, P. Gadd and A. Permana

Towra Point Nature Reserve, in Sydney’s Botany Bay, is an internationally important wetland which is at risk due to human activities. This research aimed to check whether contamination from industry and urbanisation of the region have had negative impact, and found that levels of arsenic, lead and zinc are elevated on the southern side of the embayment. We propose that trigger levels outlined in water and sediment quality guidelines should be included in the Towra Point Plan of Management, so that elevated levels will initiate a management response from relevant authorities.

Muddy waters: the influence of high suspended-sediment concentration on the diving behaviour of a bimodally respiring freshwater turtle from north-eastern Australia 
Jason R. Schaffer, Mark Hamann, Richard Rowe and Damien W. Burrows

This study represents the first investigation into the impact of elevated suspended sediment concentrations on the diving behaviour of a bimodally respiring, freshwater turtle (Elseya irwini). Our data demonstrate that increased suspended sediment directly affects the utilisation of aquatic respiration by this species to extend submergence times under optimal conditions. These observations raise concerns about the effects of erosion and catchment land management practices, on the long term sustainability of physiologically specialised freshwater turtle populations.

The effects of growth anomaly on susceptibility of Montipora capitata to turf algal overgrowth 
D. C. Claar and M. Takabayashi

Disease affects not only the biological function of coral, but it may also affect the ability of corals to compete with other species in their environment. This study evaluated the effect of growth anomalies (GAs) on the susceptibility of the coral M. capitata to algal overgrowth. The relationship between GA and algal overgrowth was weak, implying that other factors (e.g. environmental conditions) are driving this interaction.

Wandering wetlands: spatial patterns of historical channel and floodplain change in the Ramsar-listed Macquarie Marshes, Australia 
Timothy J. Ralph, Paul P. Hesse and Tsuyoshi Kobayashi

Natural channel change has caused parts of the Macquarie Marshes to be abandoned in the 20th Century and other wetland areas to form. Historical analysis shows that natural wetland changes lead to anachronistic conservation reserve boundaries where reserves include only a small portion of the floodplain. Adaptive management is required to recognise the natural dynamics of floodplain wetlands within static conservation reserve systems.

Novel method for shark age estimation using near infrared spectroscopy 
C. L. Rigby, B. B. Wedding, S. Grauf and C. A. Simpfendorfer

Reliable age information is vital for effective shark fisheries management, yet traditional ageing has some limitations. Near infrared spectroscopy (NIRS) was investigated as an alternative approach using vertebrae from the great hammerhead and the spot-tail shark, the ages of which were validated to 10 years. NIRS successfully predicted their ages, is rapid and could be used to age large numbers of sharks quickly.

Algal composition and biomass in the tropical soda lake Chitu with focus on seasonal variability of Arthrospira fusiformis (Cyanophyta) 
Tadesse Ogato, Demeke Kifle and Brook Lemma

Functions of tropical soda lakes depend heavily on algae, particularly Arthrospira, which are the basis for understanding their ecological integrity. This study, which aimed at investigating the algal dynamics in one of the fragile tropical soda lakes, revealed the occurrence of considerable seasonality of algal biomass and Arthrospira abundance following changes in environmental factors. This suggests that algal seasonality may greatly affect the values of soda lakes.

Typhoon effects on phytoplankton responses in a semi-closed freshwater ecosystem 
Chia-Ying Ko, Chao-Chen Lai, Tzong-Yueh Chen, Huang-Hsiung Hsu and Fuh-Kwo Shiah

The effects of typhoons upon freshwater ecosystem remain unclear. We analysed a 2-year time series of phytoplankton responses with typhoon events and found a significantly increased phytoplankton response both during the typhoon periods and during the non-typhoon periods occurring between two typhoons. Given that phytoplankton plays an important role in assimilating CO2 and contributes to the sinking of atmospheric CO2 to the bottom of the water column, typhoon-induced phytoplankton blooms may additionally serve to mitigate local warming under climate change.

Declining shark stocks have emphasised the need for a greater understanding of commercially targeted species. Here we assess the reproductive biology of dusky, spinner and sandbar sharks in eastern Australian waters, where all three were found to be late maturing and of low reproductive output, indicative of a low resilience to fishing pressure. This research reinforces the importance of locally-derived parameters for stock assessment.

Temporally high-frequency sampling was performed to examine rapid changes in the community composition of estuarine tintinnid ciliates. The dominant tintinnid species changed largely within several days due to changes in environmental and biological conditions. However, most tintinnid species were less vulnerable to predation pressure by copepods probably because there were many alternate prey to these predators.

Coastal defences are proliferating in response to anticipated climate change and there is increasing need for ecologically sensitive design in their construction. In this study, drill-cored artificial rock pools enhanced the ecological condition of an intertidal breakwater and supported equivalent species richness to natural rock pools. These findings reveal the potential of drill-cored rock pools as an affordable and easily replicated means of enhancing biodiversity on a variety of coastal structures, both at the design stage and retrospectively.

Selecting reference sites in highly modified landscapes is a key challenge for stream bioassessment practitioners. In this case study, generalised dissimilarity modelling was used to model fish species turnover as a function of GIS-based environmental variables to delineate ‘ecotypes’, identify influential human pressure variables and define and map candidate reference conditions. The method is transparent, indicator-specific and efficient, and complements existing procedures for defining reference conditions.

Shallow temperate reefs are among the most productive ecosystems on Earth and they are threatened by numerous natural and human-induced pressures. We present four examples that demonstrate the value of a long-term broad-scale perspective in developing a predictive understanding of the complex ecology of giant kelp forests in southern California. Increasing the number of long-term ecological research programs in highly dynamic and valued ecosystems such as kelp forests is sure to pay great dividends towards improving our understanding of the causes and consequences of ecological change now and into the future.

Feeding habits of range-shifting herbivores: tropical surgeonfishes in a temperate environment 
Alexander J. Basford, David A. Feary, Gary Truong, Peter D. Steinberg, Ezequiel M. Marzinelli and Adriana Vergés

A significant impact of ocean warming is the poleward movement of species’ distribution, including the movement of tropical herbivorous fishes into temperate algal-dominated reefs. Using aquarium feeding assays, we show that juvenile tropical surgeonfish display higher feeding rates than their warm-temperate counterparts, particularly in warmer temperatures. This may cause increased herbivory pressure on temperate reef algae as ocean temperatures rise and tropical species become more common.

We quantified diversity of mobile invertebrates associated with the seaweed Hormosira banksii and its obligate epiphyte Notheia anomala at different elevations, seasons, diurnal cycles, and following an epiphyte-removal experiment. All tests showed positive density-dependent effects of Notheia on invertebrates, with strongest facilitation at the transition from intertidal to subtidal habitats suggesting that epiphyte-driven facilitation cascades are common in marine benthic systems.

Chemicals usually appear in the environment as mixtures. The aim of the present study was to assess nickel and zinc toxicity to Mysidopsis juniae and evaluate if their joint effects could be predicted by their single toxicity. Nickel showed to be more toxic than zinc and their mixture an additivity pattern. The present study highlights the need to assess combined effects in environmental scenarios.

DNA barcoding Australian macroinvertebrates for monitoring programs: benefits and current short comings 
Michael Shackleton and Gavin N. Rees

Molecular methods are gaining recognition as an improved approach to identify freshwater macroinvertebrates for research and monitoring programs, but are not applied widely in Australia. We applied DNA barcoding to specimens collected as part of monitoring programs and found that barcode data gave considerable informational benefit on macroinvertebrates. However, a lack of available sequence data for Australian freshwater fauna limited the scope of interpretation.

Comparative assessment of aquatic macroinvertebrate diversity in irrigated rice fields and wetlands through different spatial scales: an additive partitioning approach 
Mateus Marques Pires, Carla Bender Kotzian, Marcia Regina Spies and Vanessa dos Anjos Baptista

Rice field and wetland macroinvertebrate beta diversity was compared at multiple spatial scales. In wetlands, hydrographic basin scale contributed the most to γ diversity. In rice fields, local different management practices were more important to diversity, which tends to homogenisation at broader scales. At least under drought climate conditions (ENSO phenomenon), only a small fraction of wetland community, mainly active dispersal taxa, was capable of colonising rice fields.

Age and growth dynamics of spiny dogfish, Squalus acanthias, in the Adriatic Sea (Eastern Mediterranean Sea) 
Romana Gračan, Scott A. Heppell, Gordana Lacković and Bojan Lazar

We provide first demographic parameters for endangered Mediterranean subpopulation of spiny dogfish, a commercially exploited mesopredatory shark, highly sensitive to overfishing. Our results, coming from the eastern Mediterranean basin (Adriatic Sea), suggest that the species exhibits extreme life history traits with low growth coefficients, very late sexual maturity and long life span, which intensify its vulnerability to overexploitation. This study provides critical data necessary to develop efficient, species-specific conservation strategy for the spiny dogfish in the region.

The hypoxia that developed in a microtidal estuary following an extreme storm produced dramatic changes in the benthos 
James R. Tweedley, Chris S. Hallett, Richard M. Warwick, K. Robert Clarke and Ian C. Potter

Runoff from an extreme storm led to the formation of a pronounced halocline and underlying hypoxia in the upper reaches of the microtidal Swan–Canning Estuary. The survival of annelids and loss of crustaceans during this time reflects the different sensitivities of these taxa. The results emphasise that microtidal estuaries are highly vulnerable to the effects of environmental perturbations.

Acoustic surveys can estimate the biomass of marine fishes, but need to account for turnover of fish during the spawning season. A model is developed that estimates turnover based on changes in age, size and sex during the season. It can estimate the average proportion of the spawning biomass on the spawning grounds at any point in time.

This study explored the distribution of an uncommon soft coral species, Dendronephthya australis within the Port Stephens–Great Lakes Marine Park. D. australis colonies occurred along the southern shoreline in the Port Stephens estuary, but no colonies were found within marine park sanctuary (no-take) zones. Owing to its current threats, implications from this study will assist future management, particularly in regard to its protection within a marine park.

Transient effects of an invasive kelp on the community structure and primary productivity of an intertidal assemblage 
Paul M. South, Stacie A. Lilley, Leigh W. Tait, Tommaso Alestra, Michael J. H. Hickford, Mads S. Thomsen and David R. Schiel

The invasive kelp Undaria pinnatifida is one of the world's most successful invasive species and can become highly abundant in invaded ecosystems. We tested Undaria's effects on the structure and productivity of rocky intertidal assemblages in a long-term field experiment finding that Undaria had few overall effects on community composition, but doubled local primary production when it was abundant. This study highlights the importance of considering multiple ecological aspects of species' invasions when determining their impact and has broad relevance for invasion impact studies of Undaria and other canopy-forming macroalgae.

Climate-driven shifts in species' distributions may exacerbate the impacts of storm disturbances on North-east Atlantic kelp forests 
Dan A. Smale and Thomas Vance

Kelp forests are critical habitats in temperate seas, where they are often subjected to intense wave action. The winter storm season of 2013–14 in the North-east Atlantic was unusually severe, yet kelp forests in the south-west UK were high resilient to storm disturbance. However, a warm-water kelp appeared far more susceptible to storm damage than the dominant cold-water kelp, suggesting that climate-driven shifts in species abundances may erode the resilience of some kelp forests to physical disturbance.

This is the first in situ seasonal study to investigate how freshwater autotrophic picoplankton responses to CO2 changes. CO2 elevation could significantly increase the abundance of photosynthetic picoeukaryotes in all seasons except winter, but did not have any influence on picocyanobacterial abundance. This might cause a reduction of the transfer of matter and energy to higher trophic levels and an increase the importance of the microbial food web under high CO2 levels.

We assessed the influence of riparian habitat and emergent aquatic insects on tetragnathids along the Scioto River, OH, USA. We show that nearshore physical and biological characteristics can lead to alterations in tetragnathid distribution and trophic dynamics and their capacity to serve as a functional linkage between aquatic and terrestrial ecosystems.

Triggering larval settlement behaviour and metamorphosis of the burrowing ghost shrimp, Lepidophthalmus siriboia (Callianassidae): do cues matter? 
Kácia Letícia de Noronha Campos, Fernando Araújo Abrunhosa and Darlan de Jesus de Brito Simith

Larval settlement and metamorphosis of many decapod species are triggered by physicochemical cues from the parental estuarine habitat. Here, we investigated whether the burrowing ghost shrimp (Lepidophthalmus siriboia) megalopae are stimulated by substrata and chemical cues from conspecific adults. Megalopal settlement and burrowing behaviour were induced by substrata, whereas metamorphosis to juvenile occurred irrespective of the presence or type of exogenous cues. Furthermore, megalopae developed significantly faster in the absence than the presence of substrata or conspecific stimuli. The independence of metamorphosis-stimulating cues shows important for colonisation and recovery of exploited callianassid populations.

Otolith chemistry analyses coupled with a strong latitudinal age gradient in the south-east Australian Arripis trutta population indicate that most fish originate in southern NSW, Victoria and Tasmania and move progressively northward with increasing age. Some recruitment occurs in northern NSW but these fish may not mix with immigrants from further south until they are more than 5 years old.

Sponges on coral reefs generally grow on large pieces of rock or on smaller rubble pieces that are more easily moved by water flow. Investigating the interaction of substrate stability and water flow, this study found that sponges were most abundant and grew largest on rock, particularly at shallow depths where flow rates are highest. Natural and man-made factors that change substrate composition of coral reefs will affect numbers and sizes of sponges.

Plant distribution, coupled with a knowledge of plant ecological requirements, can be informative about environmental conditions.

Over multiple timescales, we measured the pH and calculated the pCO2 of an area dominated by seagrass beds (Saint Joseph Bay, Florida). Our results indicate that diel fluctuations should be considered when designing ocean acidification experiments and that coastal species are experiencing far greater fluctuations in carbonate chemistry than previously thought.

Electrosensory-driven feeding behaviours of the Port Jackson shark (Heterodontus portusjacksoni) and western shovelnose ray (Aptychotrema vincentiana) 
R. M. Kempster, C. A. Egeberg, N. S. Hart and S. P. Collin

Interspecific variation in the elasmobranch electrosensory system remains poorly understood and as a result the functional consequences of such variation are unknown. Here, we directly tested the electrosensitivity of two benthic elasmobranchs that share a similar habitat and diet, but differ significantly in their electrosensory system morphology. The results suggest that differences in abundance and distribution of electrosensory pores have little to no effect on the absolute electrical sensitivity, and instead, may reflect species-specific differences in the spatial resolution and directionality of electroreception.

The genetic structure of bottlenose dolphin communities found along the southern Brazilian coast reveals the presence of three distinct clusters, with low gene flow between dolphins of Laguna and those from outside the estuary. Despite the movement of some individuals among the areas, significant genetic structure between dolphins was observed even among those from nearby estuaries (~219 km apart). Most of the stranded samples were revealed to be part of a possible offshore population (Cluster 3) with high levels of genetic diversity, whereas the others specimens were divided into two coastal groups (Cluster 1 and Cluster 2)

A recent dramatic decline in the settlement of post-larvae of the Western Australian spiny lobster may be due to changes in the offshore oceanographic processes. This research reported that late-stage phyllosomas of spiny lobster in cyclonic eddies of the Leeuwin Current are in a substantially better nutritional condition than are those in anticyclonic eddies.

Glassfish switch feeding from thalassinid larvae to crab zoeae after tidal inundation of saltmarsh 
Jack J. McPhee, Peter Freewater, William Gladstone, Margaret E. Platell and Maria J. Schreider

The release of free-swimming larvae (zoeae) by saltmarsh-dwelling crabs after tidal flooding of saltmarsh provides important food sources for estuarine fish, including glassfish. On ebbing tides in a temperate Australian estuary, glassfish fed on zoeae following saltmarsh flooding, but when tides flooded only the adjacent mudflats, ghost shrimp larvae were the main prey. The feeding of glassfish is therefore triggered by tidal action and the ingestion of prey is influenced by which coastal estuarine habitats are flooded by incoming tides

Effects of gear type, entrance size and soak time on trap efficiency for freshwater crayfish Cherax destructor and C. albidus 
Paul Brown, Taylor L. Hunt and Khageswor Giri

We aimed to compare relative efficiencies of six gears where an array of restrictive recreational fishing regulations are in place for freshwater crayfish. Open topped traps and those fitted with fixed entrance rings, to reduce by-catch entry, were most efficient particularly when fished actively with short soak-times. Encouragingly, fixed entrance rings didn’t affect catch efficiency or size-structure.

Variability in the growth, feeding and condition of barramundi (Lates calcarifer Bloch) in a northern Australian coastal river and impoundment 
D. J. Russell, F. E. Thomson, P. A. Thuesen, T. N. Power and R. J. Mayer

Growth of stocked and wild Lates calcarifer in some north Queensland habitats was both seasonal and prey-dependent. In the lower, freshwater Johnstone River, where larger prey appeared depauperate, L. calcarifer grew slower relative to those in downstream estuarine and adjacent coastal areas and in nearby Lake Tinaroo. Growth of L. calcarifer was highly seasonal with marked declines during the cooler months.

River metabolism and carbon dynamics in response to flooding in a lowland river 
Robert A. Cook, Ben Gawne, Rochelle Petrie, Darren S. Baldwin, Gavin N. Rees, Daryl L. Nielsen and Nathan S. P. Ning

Floodwater returning from floodplains can contain large amounts of carbon, but it’s not well understood whether or not this carbon is involved in the carbon budgets of rivers. We examined carbon dynamics upstream and downstream of a river red gum forest, before and after a flood inundated the forest and returned to the river. The flood waters led to a major increase in the carbon budget of the river and the carbon was processed by riverine biofilms, showing carbon from the floodplain can fuel river foodwebs.

Sea-surface temperature used to predict the relative density of giant Pacific octopuses (Enteroctopus dofleini) in intertidal habitats of Prince William Sound, Alaska 
D. Scheel

I used targeted visual surveys to study giant Pacific octopuses, Enteroctopus dofleini, an important by-catch species in pot fisheries in Alaska. I found a significant negative correlation of octopus counts with winter sea-surface temperatures over the past 30 months. Environmental variables affecting recruitment together with visual surveys may allow better prediction of trends in octopus abundance than by-catch statistics.

The association between coral communities and disease assemblages in the Wakatobi Marine National Park, south-eastern Sulawesi, Indonesia 
J. Haapkylä, J. Melbourne-Thomas and M. Flavell

The Coral Triangle, including Indonesia, is a hotspot for coral reef diversity, but the effects of coral disease in this region are poorly understood. This study reports changes in coral cover and disease prevalence in a remote part of Indonesia, and relates these changes to features of the coral community. Declines in coral cover and increases in both the number of diseases and overall disease prevalence over a 7-year period underlie potential changes in coral communities in this biodiversity hotspot.

Spatial and temporal habitat use by white sharks (Carcharodon carcharias) at an aggregation site in southern New Zealand 
Malcolm P. Francis, Clinton Duffy and Warrick Lyon

White sharks aggregating at fur seal colonies near Stewart Island, southern New Zealand, were tagged to identify their temporal and spatial patterns of occupancy, and to inform management measures that aim to separate sharks from fishing effort. White sharks were present from late summer to early winter, peaking in autumn (March–June). The population comprised mainly subadult and adult males and subadult females, and individual sharks showed fine-scale spatial and temporal variability in abundance. These sharks travel well beyond their aggregation sites, but the behaviour and dynamics of white sharks in other parts of New Zealand remain poorly understood.

Resilience to climate change: complex relationships among wetland hydroperiod, larval amphibians and aquatic predators in temporary wetlands 
Katrin Lowe, J. Guy Castley and Jean-Marc Hero

The environmental factors influencing breeding of a temporary wetland breeding frog (Litoria olongburensis) from eastern Australia were examined. The species showed breeding flexibility in response to highly variable and unpredictable rainfall conditions. This flexibility may reflect an adaptive capacity to predicted changes in frequency and reliability of precipitation as a result of climate change, and may apply to other temporary wetland species.

Behavioural responses to simulated bird attacks in marine three-spined sticklebacks after exposure to high CO2 levels 
Joacim Näslund, Erik Lindström, Floriana Lai and Fredrik Jutfelt

Ocean acidification (OA), caused by increased levels of carbon dioxide (CO2) in the sea water, has previously been reported to affect the behaviour of fishes. Here, we find that some behaviours (lateralisation and freezing) were affected by OA in three-spined sticklebacks, but the general response to a bird predator (spatial avoidance) was not affected. Thus, the general avoidance behaviour appears to be robust to elevated CO2 levels, despite some behaviours being altered.

Patterns of connectivity and population structure of the southern calamary Sepioteuthis australis in southern Australia 
Timothy M. Smith, Corey P. Green and Craig D. H. Sherman

Southern calamary are an important fisheries species and understanding levels of connectivity across their distribution is important for management purposes. Genetic discrimination techniques suggested that there is a high level of gene flow and connectivity throughout their distribution. Such results indicate the southern calamary population has the potential to maintain a level of resilience to altering conditions if large scale mixing is maintained.

Soft bodies make estimation hard: correlations among body dimensions and weights of multiple species of sea cucumbers 
James Prescott, Shijie Zhou and Andhika P. Prasetyo

Sound management of sea cucumber fisheries requires biological information including body measurements. We used hierarchical Bayesian errors-in-variables models to establish correlations among three types of weight measures and two body dimensions. The results can be applied to sea cucumbers in other areas and can be useful for data standardisation and size-based fisheries management.

Temperature, length of growth season and phytoplankton abundance in the Gulf of Maine 
blank image
Knut Seip
pp. 759-766

Does global warming of the sea surface decrease or increase phytoplankton abundance? This paper shows that, although within-season phytoplankton abundance decreases with increasing water temperature, annual average phytoplankton abundance increases with average water temperature, likely because an increase of 1°C lengthens the growth season by ~20 days. However, it is not known if higher annual average phytoplankton abundance translates into larger stocks of zooplankton and fish.

Mobulid ray by-catch in longline fisheries in the south-western Atlantic Ocean 
blank image
F. Mas , R. Forselledo and A. Domingo
pp. 767-777

This paper presents the first by-catch assessment of mobulid rays in pelagic longline fisheries over the south-western Atlantic. At least two species were indentified and, although by-catch frequency was low, some uncertainties remained regarding their post-capture mortality. This work sheds light on mobulids’ interaction with longline fisheries, expands known distribution ranges, and raises concern about the potential effect of these fisheries on mobulid populations.

pp. 778-785

Imposex is mainly caused by organotins’ accumulation in gastropods tissues. This research aimed to study the imposex in of Stramonita haemastoma individuals collected along the rocky coastline of the Gulf of Tunis. Sexual modifications occurred to different degrees in all stations essentially close to harbours. An inverse relationship between the distances from harbours and the occurrence of imposex was observed.

The effect of boat anchoring on the Mediterranean endemic bivalve Pinna nobilis was assessed experimentally in the field by deploying non-biological mimic units. Boat anchoring influence was three times higher in affected than in control areas, having also an adverse effect on Posidonia oceanica meadows. Moreover, lower values of natural P. nobilis density and size classes were recorded from the affected areas.

pp. 805-814

Understanding the role of agriculture in water quality and river health is vital. This study investigated the effect of agricultural run-off on the chemical and biological status of the hyporheic zone, and indicates that hyporheic zones are degraded in intensely farmed catchments. These findings emphasise the importance of holistic catchment management in the protection and sustainability of freshwater systems.

Timoteo Tadashi Watanabe , Gustavo Yomar Hattori and Bruno Sampaio Sant’Anna
pp. 815-821

The present study investigated the behaviour of the apple snail Pomacea bridgesii on a simulated flood-pulse water regime. The results show that there are differences between day and night behaviours (activity and substrate selection). There were also differences between behaviours in dry and maximum water-level periods. Therefore, the floodplain regime influences the activity of P. brigesii displaying adaptations to minimise water loss.

pp. 822-830

Understanding the links between fish recruitment and riverine flows is integral for setting priorities for river-management strategies. We found that within-channel flow events soon after months of no-flow were important spawning triggers for the endemic Lake Eyre golden perch (Macquaria sp.). Subsequent fish recruitment was also strongly associated with the number of flow-events per year. These results highlight the importance of maintaining the naturally variable flow regime of Australia’s arid- and semi-arid zone rivers.

Artificial irrigation ponds and sea coast as foraging habitat for larids breeding in protected wetlands

pp. 831-840

Questions related to the preservation of foraging sites of breeding birds have received little attention, although they can be of major importance for population persistence. Here, we used stable isotopes and field observations to evaluate the relative importance of man-made irrigation ponds as foraging areas for a larid community of conservation concern. Our study showed that larids breeding in mixed colonies segregate spatially in their foraging niche between marine and freshwater environments. Both breeding and foraging habitats need to be addressed when analysing larid population dynamics and conservation strategies.

Breeding habitat selection in an obligate beach bird: a test of the food resource hypothesis

pp. 841-846

One beach is not the same as another as far as a beach nesting-bird, the Hooded Plover, is concerned. They breed in sites with more invertebrate prey, and which have different assemblages of prey species, compared with sites where they do not breed. Thus, beaches apparently vary in terms of their ability to support this threatened bird species.

High clonality in Acropora palmata and Acropora cervicornis populations of Guadeloupe, French Lesser Antilles

pp. 847-851

In Guadeloupe, the two endangered Acropora species are critically declining, like in the rest of Caribbean reefs. While examining the genetic status of two main remnant populations, we found an extremely high clonality in both species. This is alarming in the context of ongoing global warming as long periods of clonal growth without sexual recruitment may lead to the extinction of these populations.

Year-round maturity of the chaetognath Aidanosagitta regularis in the Hauraki Gulf, New Zealand

Wesley H. Webb and Mary A. Sewell
pp. 852-856

The reproductive biology of planktonic chaetognaths is poorly known, particularly with regard to the importance of seasonal factors. We undertook a year of semilunar plankton sampling in the Hauraki Gulf, New Zealand, to survey sexual maturity of Aidanosagitta regularis; surprisingly, breeding of A. regularis appeared unconstrained by seasonal factors, as reproductively mature individuals were available year-round. This has implications for embryological study of the chaetognaths.
