A host-specific habitat former controls biodiversity across ecological transitions in a rocky intertidal facilitation cascade 
Mads S. Thomsen, Isis Metcalfe, Paul South and David R. Schiel

Few studies have quantified facilitation cascades across ecological transition zones or where the secondary facilitator is an obligate epiphyte. 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.

Zinc and nickel binary mixtures act additively on the tropical mysid Mysidopsis juniae 
Lívia Pitombeira de Figuerêdo, Jeamylle Nilin, Allyson Queiroz da Silva, Évila Pinheiro Damasceno, Susana Loureiro and Letícia Veras Costa-Lotufo

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.

Estimating the dynamics of spawning aggregations using biological and fisheries data 
André E. Punt, David C. Smith, Malcolm Haddon, Sarah Russell, Geoffrey N. Tuck and Tim Ryan

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.

Distribution and spatial modelling of a soft coral habitat in the Port Stephens–Great Lakes Marine Park: implications for management 
Davina E. Poulos, Christopher Gallen, Tom Davis, David J. Booth and David Harasti

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.

A test of metabolic and consumptive responses to local and global perturbations: enhanced resources stimulate herbivores to counter expansion of weedy species 
Chloe McSkimming, Bayden D. Russell, Jason E. Tanner and Sean D. Connell

Trophic compensation by herbivores negated the effect of local (nitrogen) and global pollution (CO2) on the expansion of algal turfs. This resource enrichment stimulated an increase in metabolic activity of herbivores so that the additional productivity of kelp competitors was consumed.

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.

The effect of elevated CO2 on autotrophic picoplankton abundance and production in a eutrophic lake (Lake Taihu, China) 
Shengnan Li, Jian Zhou, Lijun Wei, Fanxiang Kong and Xiaoli Shi

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.

Genetic analyses reveal declining trends and low effective population size in an overfished South African sciaenid species, the dusky kob (Argyrosomus japonicus) 
Luca Mirimin, Brett Macey, Sven Kerwath, Stephen Lamberth, Aletta Bester-van der Merwe, Paul Cowley, Paulette Bloomer and Rouvay Roodt-Wilding

Overfishing has led to the collapse of many marine fish stocks. In this study, genetic markers were utilised to investigate population structure and genetic relatedness in an overfished South African fish species, the dusky kob. Results showed low genetic structuring and declining population trends, which should be taken into account for future management and conservation of depleted dusky kob populations.

Distribution and trophic dynamics of riparian tetragnathid spiders in a large river system 
Paradzayi Tagwireyi and S. Mažeika P. Sullivan

Riparian tetragnathid spiders are important components of river–riparian food webs. 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.

How good are we at assessing the impact of ocean acidification in coastal systems? Limitations, omissions and strengths of commonly used experimental approaches with special emphasis on the neglected role of fluctuations 
M. Wahl, V. Saderne and Y. Sawall

Much of the past research on ocean acidification suffers from too simple experimental design. We present weak spots of many common approaches with a strong emphasis on the disregard of natural fluctuations. Experiments up scaled along the suggested dimensions are likely to provide more realistic results.

Relationship between otolith chemistry and age in a widespread pelagic teleost Arripis trutta: influence of adult movements on stock structure and implications for management 
Julian M. Hughes, John Stewart, Bronwyn M. Gillanders, Damian Collins and Iain M. Suthers

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.

Substrate type affects the abundance and size of a coral-reef sponge between depths 
Alan R. Duckworth

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.

Cusps and butterflies: multiple stable states in marine systems as catastrophes 
P. S. Petraitis and S. R. Dudgeon

The theory of alternative stable states is often used to explain rapid and difficult to reverse shifts between different community states that commonly occur in ecosystems. Here this idea is re-examined in terms of catastrophe theory, a theory that has been largely overlooked by ecologists. The well-known hallmarks of catastrophes can provide new experimental tests for alternative states in nature.

Historical water-plant occurrence and environmental change in two contrasting catchments 
Michelle T. Casanova

Water-plant distribution is determined (in part) by water regime and salinity, so we can infer historical water regime and salinity from historical plant distribution. It was found that there were more records of drought-and salinity-tolerant plants along the Angas River and Tookayerta Creek in present-day surveys than in the past. Plant distribution, coupled with a knowledge of plant ecological requirements, can be informative about environmental conditions.

Improving our ability to collect eggs of the threatened Australian grayling, Prototroctes maraena 
F. Amtstaetter, D. Dawson and J. O'Connor

This research investigates whether sampling techniques for capturing eggs of the threatened Prototroctes maraena can be improved to monitor spawning success. Paired drift net sets (just below the surface versus on the bottom) were compared to identify that most eggs (90%) were captured on bottom and as a result egg density was higher. Recommendations are made for future sampling and implications for other species with negatively buoyant eggs discussed.

Variability of the carbonate chemistry in a shallow, seagrass-dominated ecosystem: implications for ocean acidification experiments 
Roberta C. Challener, Lisa L. Robbins and James B. McClintock

Few studies have characterised the carbonate chemistry of nearshore coastal zones. 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.

UV radiation effects on the embryos of anchoveta (Engraulis ringens) and common sardine (Strangomera bentincki) off central Chile 
P. Vásquez, A. Llanos-Rivera, L. R. Castro and C. Fernandez

Observed levels of ultraviolet B (UVB) radiation off central Chile (36°S, 73°W) indicate that planktonic fish embryos from anchoveta (Engraulis ringens) and common sardine (Strangomera bentincki) were exposed to harmful UVB radiation levels which in the field can cause a decrease in hatching success, embryonic malformations and changes in buoyancy.

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.

Bottlenose dolphin communities from the southern Brazilian coast: do they exchange genes or are they just neighbours? 
Ana Paula Borges Costa, Pedro Fruet, Fábio Gonçalves Daura-Jorge, Paulo César Simões-Lopes, Paulo Henrique Ott, Victor Hugo Valiati and Larissa Rosa de Oliveira

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)

Phosphorus is vulnerable to the artificial lake, and sensitive to aquatic ecosystems. Phosphorus dynamics in a huge reservoir should be well documented, and the Three Gorges Reservoir exerts important influence on phosphorus speciation and transport. This study will improve our understanding of the mechanisms and processes responsible for the effect of artificial lake with a unique gradual mode of impoundment.

What drives variation in estuarine epibiota community structure? By testing relationships among multiple environmental factors, various biogenic substrates and the richness and abundance of epibiota, this study investigates possible underlying drivers of variation in epibiotic communities. The results clearly demonstrate the importance of including multiple environmental factors in future studies to provide better prediction of the distribution and changes of epibiota communities.

Condition of larvae of western rock lobster (Panulirus cygnus) in cyclonic and anticyclonic eddies of the Leeuwin Current off Western Australia 
Miao Wang, Richard O'Rorke, Anya M. Waite, Lynnath E. Beckley, Peter Thompson and Andrew G. Jeffs

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. These differences may be related to differences in water temperatures and would influence their settlement.

Growth and spatiotemporal distribution of juvenile shortfin mako provide valuable information on their potential productivity, mechanisms of recruitment and movement. The aims of this study were to estimate the growth and to explore the distribution. The shortfin mako growth was faster than previously reported – sharks were born during autumn and winter off the coast of north-eastern Japan, and gradually expanded their habitat eastward and northward.

Ciguatera fish poisoning is frequent in southern coastal China. Ciguatera toxins (CTXs) in wild coral reef fish collected from the southern coast of China were analysed, and 47.8% of the samples were confirmed to be contaminated with CTXs. There was no significant correlation between fish toxicity and fish weight, length and feeding habits. The present study posed a huge question concerning the management of ciguatera toxins in China.

Daryl L. Nielsen, Elke Walburga Jasper, Nathan Ning and Susan Lawler

Many wetland plants and invertebrates in wetland communities survive the dry periods as dormant seeds and eggs. We determined that the viability of seeds decreased at temperatures at above 50°C and for invertebrates at temperatures at above 40°C. These results indicate that changes to sediment temperature during the dry phase of wetlands may play an important role in influencing communities of wetland plants and invertebrates.

Can top-down and bottom-up forces explain phytoplankton structure in a subtropical and shallow groundwater-connected lake? 
Diego Frau, Melina Devercelli, Susana José de Paggi, Pablo Scarabotti, Gisela Mayora, Yamila Battauz and Mariana Senn

Top down–bottom up is one of the major hypotheses that explain aquatic communities’ structure. In this study we aim to prove it in a subtropical shallow lake using phytoplankton as study object. We realised that phytoplankton is mainly regulated by hydrological changes that affect nutrient availability and predation. Evidence suggest that top down–bottom up model is not completely valid for shallow subtropical lakes where new models should be fashioned.

Low survival rather than breeding success explains little penguin population decline on Granite Island 
Diane Colombelli-Négrel

Little penguin populations have been seriously declining across South Australia, for reasons still not fully understood. I investigated breeding performance and survival of little penguins on Granite Island for 17 years and found that both adult and sub-adult survivals were extremely low, with sub-adult survival being the most critical variable affecting population growth. Further investigation into factors influencing juvenile mortality is clearly needed, with a particular focus on food availability and parasites, which are known reasons for poor juvenile survival in other colonies.

Significant genetic structure despite high vagility revealed through mitochondrial phylogeography of an Australian freshwater turtle (Chelodina longicollis) 
K. Hodges, S. Donnellan and A. Georges

The turtle Chelodina longicollis is a freshwater obligate with strong overland dispersal capacity and adaptations to terrestriality – traits that connect populations and reduce divergence. Genetic results showed two ancient haplogroups partitioned either side of the Great Dividing Range, each with demographically stable subpopulations and signals of isolation by distance. These results demonstrate that that landscape history can overwhelm life-history traits even in a highly vagile species.

Populations from an endemic lineage out of its reported natural range difficult the management of species diversity. The phylogeny of mtDNA sequences demonstrated the natural origin of the brown trout populations of the Duero lineage outside the Duero basin, and refused its origin from recent human translocations. This lineage singularity into the north-western Iberian rivers will require differentiated management from Duero lineage populations inside the Duero basin.

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

The native seaweed Caulerpa filiformis has reportedly been spreading over rocky reefs throughout NSW. We document the extent of C. filiformis over 5 years and test whether the seaweed is associated with nutrient enrichment and particular habitat types. C. filiformis is predominately found where there is a mixture of rocky reefs and beaches and is not closely associated with human activities or nutrient levels over large areas.

New opportunities for conservation of a threatened biogenic habitat: a worldwide assessment of knowledge on bivalve-reef representation in marine and coastal Ramsar Sites 
Tim Kasoar, Philline S. E. zu Ermgassen, Alvar Carranza, Boze Hancock and Mark Spalding

Bivalve reef has recently been listed under the Ramsar Convention (1971), thereby requiring reporting of its presence. The present study aimed to assess the current state of knowledge of bivalve reef represented in Ramsar Information Sheets, and found that only 2% of Sites reported the presence of bivalve reef, whereas 16% of Sites were identified using other data sources. These Sites should be a priority for surveys to confirm the presence or absence of this important marine habitat.

Little is known about the sensitivity of freshwater elasmobranchs to minute electric fields produced by their prey. This study determined that the obligate freshwater stingray, Potamotrygon motoro, is up to 5 orders of magnitude less sensitive to electric fields than its marine relatives. Despite decreased electrosensitivity, P. motoro still successfully localises prey owing to multiple sensory systems working synergistically.

Reproductive capacity of a marine species (Octopus tetricus) within a recent range extension area 
Jorge E. Ramos, Gretta T. Pecl, Jayson M. Semmens, Jan M. Strugnell, Rafael I. León and Natalie A. Moltschaniwskyj

Marine species undertaking range shifts in response to environmental change must produce viable gametes and their offspring must survive in new areas. Examination of reproductive characteristics suggests that Octopus tetricus can reproduce and the population may be self-sustainable within its new range in south-eastern Australia. The reproductive biology of O. tetricus may thus facilitate the establishment and prevalence of the population in the new environments.

Importance of predation and viral lysis for bacterial mortality in a tropical western Indian coral-reef ecosystem (Toliara, Madagascar) 
M. Bouvy, P. Got, Y. Bettarel, T. Bouvier, C. Carré, C. Roques, M. Rodier, J. C. Lope and R. Arfi

Viral lysis may be a major cause of mortality and, at times, comparable to grazing-induced mortality. We compare the two distinct processes of bacterial mortality in two different trophic conditions using natural populations. Changes in nutrient concentrations can play an important role in the balance between viral lysis and heterotrophic nanoflagellate grazing in the bacterial mortality.

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.

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.

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.

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.

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

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.

Artificial irrigation ponds and sea coast as foraging habitat for larids breeding in protected wetlands 
Esther Sebastián-González, Francisco Botella, Otso Ovaskainen, Antonio Delgado and José Antonio Sánchez-Zapata

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.

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.

Year-round maturity of the chaetognath Aidanosagitta regularis in the Hauraki Gulf, New Zealand 
Wesley H. Webb and Mary A. Sewell

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.

Lake Eyre golden perch (Macquaria sp.) spawning and recruitment is enhanced by flow events in the hydrologically variable rivers of Lake Eyre Basin, Australia 
B. J. Cockayne, D. Sternberg, D. W. Schmarr, A. W. Duguid and R. Mathwin

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.

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.

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.

Temperature, length of growth season and phytoplankton abundance in the Gulf of Maine 
Knut Seip

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.

Reef-fish communities on large coral-reef systems are incredible complex; in contrast, isolated oceanic islands represent an opportunity to understand processes on ecologically simpler ecosystems. This study investigated the reef-fish community of the world’s smallest tropical oceanic island and found that environmental drivers, especially depth, are more important than biotic interactions in its organisation, probably because of low species-richness. The low-species richness translates in low functional redundancy, indicating that remote islands may be more vulnerable to human impacts than interconnected reef systems.

Sampling muscle is the prevalent technique for stable isotope analysis in fish and typically involves the death of the individuals. Fin-clipping is a non-lethal, easy-to-implement sampling technique that preserves fish welfare. This study assessed the suitability of caudal fin as a replacement for muscle in trophic studies. Results support the use of caudal fin as a surrogate for muscle but also showed that fin-muscle relationship varies among species and it is affected by fish size.

Low summer oxygen in a highly eutrophic and seasonally hypoxic coastal bay was attributed to high phytoplankton stocks, together with high temperature and stratification of the water column. A distinct mesozooplankton community was identified in summer of large freshwater discharge. The abundance of a marine cladoceran was positively related to oxygen levels, suggesting that hypoxic conditions may have lethal or sublethal effects.

Understanding the mechanisms that favour increase in phytoplankton biomass and bloom formation in freshwater ecosystems is a major challenge for managers and researchers, especially in environments dominated by cyanobacteria. Based on 5 years of observation, our study evaluated the importance of climatic factors in determining environmental conditions such as water level and mixing regime in a subtropical lake used for public water supply. The results show the importance of daily stratifications events for the accumulation of phytoplankton biomass.

The breeding aggregation of the giant Australian cuttlefish (Sepia apama) in northern Spencer Gulf, Southern Australia, has declined dramatically since the turn of the century. Our analysis of long-term by-catch and harvest records for the population indicated that this trend was not due to the failure of the species to aggregate, nor due to the aggregation occurring elsewhere, but was part of a systemic decline in the abundance of the population over this period. We evaluated a suite of potential climatic and harvest-related stressors for this species but could not attribute this decline in abundance to specific causes.

The decline of seagrass beds has been accelerated by opportunistic macroalgae blooms. The feeding behaviour of mudsnail Peringia ulvae was studied with the aim of assessing its potential role in preventing the occurrence of macroalgal blooms. Snails grazed on all opportunistic macroalgae tested; however, sediment was the feeding niche preferred. Therefore, the hypothesis that P. ulvae has a role in preventing macroalgal blooms was not supported.

The declining cover of stony corals on tropical reefs is at the centre of the coral reef crisis, and while much is known about the factors killing corals, little is known about the factors determining their ability to replace themselves. In this paper we exploit four well-studied coral reef locations in the Caribbean and Pacific to evaluate the role of long-term variation in coral recruitment and the success of young corals in driving changes in coral cover. Our results reveal dramatic differences among locations in the capacity of corals to replace themselves through sexual reproduction (i.e. post-settlement success), with these effects probably playing an important role in determining the rate at which coral cover is lost (or gained) on present-day reefs.

Populations of kōura, or freshwater crayfish (Paranephrops planifrons), were quantified along a eutrophication gradient in seven Te Arawa lakes using the tau kōura, a traditional Māori harvesting method. Our results suggest that benthic substrate is more important in determining kōura population abundance than nutrient enrichment (using chlorophyll-a as a proxy) or predatory fish (rainbow trout abundance). Lake trophic status in conjunction with lake morphology appeared to indirectly affect kōura distribution in the sheltered, steep sided lakes, through hypolimnetic deoxygenation.
