Buckling, bending and penetration response of the Taraxacum officinalae (Dandelions) to macadam loading 
Peter R. Greene and Virginia A. Greene

Dandelion plants (Taraxacum officinalae) can lift an overhead weight of 2–3 N, sustaining this force for 3–4 weeks, causing yielding and cracking of an 8 cm thick macadam surface. Euler buckling theory was applied to experiments on flower stems and leaf stalks, estimating stresses, strains and modulus of the plant-tube wall, under heavy loading from overhead weight.

Knowledge of the reproductive ecology of the invasive Salix cinerea, in its invaded range, assists in more targeted management strategies 
Tara Hopley and Andrew G. Young

A better understanding of the reproductive ecology of invasive species can assist land managers in developing effective control strategies. In its invaded range Salix cinerea was found to be ambophilous with both insects and wind playing a role in pollination while initial germination was found to be high but seed were short-lived. These results show a limited seed bank is available for this species highlighting that reducing seed set and dispersal should reduce reinfestation.

Conservation biology of two endemic Beyeria species (Euphorbiaceae) from southern Western Australia 
Brian J. Vincent, Sarah Barrett, Anne Cochrane, Julie A. Plummer and Michael Renton

We sought to understand and contrast the ecology of two endemic species of Beyeria (plant family Euphorbiaceae) from southern Western Australia. Unexpectedly, the more common and widespread Beyeria villosa appeared to have lower reproductive fitness than the very restricted B. cockertonii. However, B. cockertonii appeared dependent on a specific insect pollinator and this, along with habitat specificity, may render it vulnerable to threatening processes. The study will inform the conservation management of these species that are threatened by mining activities.

An evaluation of the genetic structure of seed sources and the maintenance of genetic diversity during establishment of two yellow box (Eucalyptus melliodora) seed-production areas 
Linda M. Broadhurst, Graham Fifield, Bindi Vanzella and Melinda Pickup

Seed production areas (SPAs) are one way to ensure the regular supply of high genetic quality seed for restoration. This evaluation of two Yellow Box SPAs found that genetic diversity is similar to that of natural populations. These SPAs will provide high quality seed for future restoration projects and reduce the need to collect from wild populations.

Dormancy is modulated by seed structures in palms of the cerrado biome 
V. S. Carvalho, L. M. Ribeiro, P. S. N. Lopes, C. O. Agostinho, L. J. Matias, M. O. Mercadante-Simões and L. N. F. Correia

Seeds of species adapted to the environments with seasonal climates commonly have sophisticated mechanisms for delaying germination, which contributes to the development of plants in favourable occasions. In this paper we investigate how the structures of palm seeds of Cerrado (Brazilian savannah) influence germination. We found that differences in both the embryo size as the seed coat thickness make the germination be distributed over time, which affects the pattern of geographic distribution of species.

Reproductive success of Acacia longifolia (Fabaceae, Mimosoideae) in native and invasive populations 
Marta Correia, Sílvia Castro and Susana Rodríguez-Echeverría

More and bigger seeds contribute to the invasive success of the Australian species A. longifolia in Portugal. This study compared selfing and reproductive success of A. longifolia showing no changes in selfing but an increase in the quantity and size of the seeds produced in the invaded region even for self-pollinated fruits. Intercontinental comparisons, such as this, are scarce but essential to understand invasion by exotic plants.

Conservation genetics and geographic patterns of genetic variation of the vulnerable officinal herb Fritillaria walujewii (Liliaceae) 
Zhihao Su, Borong Pan, Stewart C. Sanderson, Xiaojun Shi and Xiaolong Jiang

Population genetics and evolutionary histories of threatened plants need to be understood to establish effective conservation strategies. We studied the genetic patterns of Fritillaria walujewii and found that Xinyuan County is the centre of diversification, and that populations in the eastern Tianshan Mountains were colonised from the Yili Valley. This information will provide prudent management strategies for its recovery.

Cytological study of Polystichum (Dryopteridaceae) species from southern South America 
Rita E. Morero, Franco E. Chiarini, Juan Urdampilleta, Gloria E. Barboza and David S. Barrington

This study provides the first cytological approach on nine Polystichum species in order to increase our understanding of their systematic relationship. We found 2x, 4x and 8x ploidy levels, genome downsizing in polyploids, sexual reproduction, and spore size correlated with ploidy level. These evidences and a cytological literature survey suggest different evolutionary paths between species from southern South America and those of northern and central Andes Mountains.

Developmental phenology of Persoonia longifolia (Proteaceae) and the impact of fire on these events 
K. A. Chia, J. M. Koch, R. Sadler and S. R. Turner

We undertook a comprehensive study over a 3-year period to detail the growth, flowering, fruiting and germination biology of Persoonia longifolia (snottygobble). Plants produced vegetative growth, flowers and fruit during summer months and germination occurred during late winter from seed that is at least 1-year old, with these responses affected by fire. This research is vital for developing methods of returning this plant to rehabilitated areas of the jarrah forest, in south-western Australia.

The reproductive biology of the introduced root holoparasite Orobanche ramosa subsp. mutelii (Orobanchaceae) in South Australia 
Jane Prider

Knowledge of the seed production of invasive species is vital for weed risk assessments and control programs. We investigated aspects of the seed production of broomrape and found that each flower can produce over 1000 viable seeds within 10 days of the flower dying. This species has similar seed traits to other broomrapes which are important weeds of crops worldwide.

The role of phosphorus deficiency in nodule microbial composition, and carbon and nitrogen nutrition of a native legume tree in the Cape fynbos ecosystem 
Anathi Magadlela, Waafeka Vardien, Aleysia Kleinert, Léanne L. Dreyer and Alexander J. Valentine

Legumes native to low-nutrient ecosystems need atmospheric nitrogen to survive. Phosphorus deficiency in the nodule bacterial composition’s role in biological nitrogen fixation (BNF) was investigated and it was found that BNF was more efficient, even though the bacterial composition was unaffected. The bacterial species inside legume nodules may be highly adapted to function in P-poor soils, for host N provision.

Practical and theoretical implications of a browsing cascade in Tasmanian forest and woodland 
Alister Hazeldine and Jamie B. Kirkpatrick

Animal browsing can transform tree and forest. We found that wallabies and pademelons preferred to eat prickly box and native cherries, and avoided many wattles, but would eat all small trees as seedlings. Their browsing appeared to keep dry forests more open, and less prone to fire damage, than would otherwise have been the case.

Determining maturity and population structure in Macrozamia parcifolia (Zamiaceae), a threatened Australian cycad 
Adrian C. Borsboom, Jian Wang and Paul I. Forster

Worldwide there are many threatened cycads, and for trunkless species, determining what constitutes a mature plant and incorporating this information into a population structure is difficult. Demonstrated for one threatened, trunkless Australian cycad is a new, simple and effective method of determining maturity and population structure. This method and the knowledge derived will aid in its conservation management, and could be applied to other threatened cycads.

The flora of ultramafic soils in the Australia–Pacific Region: state of knowledge and research priorities 
blank image
Antony van der Ent , Tanguy Jaffré , Laurent L’Huillier , Neil Gibson and Roger D. Reeves
pp. 173-190

In the Australia–Pacific Region ultramafic soils cover large surface areas. In New Caledonia 2150 plant species (83% endemic) are known from these soils. This compares to 1355 taxa in Western Australia and 553 species in Queensland. Ni hyperaccumulator species number 65 in New Caledonia, one in Western Australia and two in Queensland. There is a need for evolutionary research on hyperaccumulation.

Mount Kinabalu, Borneo, with the summit elevation of 4095 m and diverse geology, is one of the global centres of plant diversity. By using vegetation sample plots, we compared the tropical montane rain forests over ultramafic soils with those over non-ultramafic soils on Mount Kinabalu, and also with those on other mountains with ultramafic soils in South-east Asia. The results demonstrated the uniqueness of the ultramafic vegetation on Mount Kinabalu.

pp. 216-221

Landslide occurrences is a natural phenomenon that can be mitigated by using Chrysopogon zizanioides or vetiver grass. In this research, vetiver grass was evaluated as a potential plant for landslide bioengineering purposes. The results of the study showed that the vetiver grass grows well in the experimental site, which shows that the grass has a potential in landslide bioengineering.

Extended vegetation histories from ultramafic karst depressions 
blank image
Geoffrey Hope
pp. 222-233

Rocks high in iron and magnesium are moderately soluble in wet tropical climates and land-surface features such as sinkholes are formed, similar to those in limestones. Low nutrients and heavy metal toxicity slow the build-up of organic matter in many of these hollows and they can preserve records of long-term vegetation change over 50 000 years ago. Dating of the organic material is not straightforward in these open systems and chronological problems limit the studies in some cases.

Methods of Remote Sensing appear promising in detection and mapping of typical ultramafic vegetation in the Andaman Island, India. Image analyses coupled with various transformations and vegetation studies, in the otherwise inaccessible area, helped in identifying the typical vegetation being composed of stunted evergreen shrubs. This vegetation, representing an ecosystem island, needs further survey and biogeochemical analyses for conservation.

pp. 243-251

A typical dwarfed sclerophyllous vegetation is found to occur in some parts of north and south Andaman where outcrops of ophiolite occur. A total of 11 hyperaccumulators of nickel were identified from there, belonging to eight genera and seven families. Of these, six species are additions to the list of hyperaccumulators and three species as hemiaccumulators.

pp. 252-260

Elemental composition of plants from the serpentine soil of in Sugashima Island, Japan was investigated. Plants had a tendency to accumulate Ni in high correlation with Fe, but Buxus microphylla, had the highest Ni concentration with the average Fe level. This suggests that plants that accumulate high Ni but low Fe may be more adaptive for serpentine soil environment.

We investigated the role of bacterial–fungal interactions on heavy metal uptake by Zea mays plants. Soil nutrients and soil enzyme activities were also measured to determine the effect of microbial inoculations on soil quality. We report the synergistic effect of bacterial–fungal inoculation in enhancing soil-quality and promoting plant growth in the presence of heavy metals.

pp. 269-275

Neoroepera buxifolia is an endemic shrub to small tree that is restricted to the creeks, riverbanks and drainage lines of the central Queensland ultramafic landscape. It is associated with high levels of soil magnesium and this study seeks investigate the relationships of N. buxifolia with the soil elements. Nickel in the soil had the greatest positive influence on tree height and the standing volume was greatest in the upper tributaries.

pp. 276-291

This work compares lichen colonisation on different ultramafic lithologies, exploring metabolic adaptation to substrate-related metal stress. Physical factors such as surface disaggregation determine lichen abundance on the different lithologies, whereas the presence or absence of certain secondary metabolites accounts for a community-level adaptation to different metal concentrations in the colonised rocks. This research contributes to knowledge of biological adaptation to metal stresses in natural environments and of the ecological significance of lichen secondary metabolites.

pp. 292-307

Local biodiversity and endemic species are being endangered as an historically unique woodland system is succumbing to encroachment. This work used an integrated approach combining data from geology, ecology and soils to examine the successional trajectory of a unique woodland ecosystem. The data show that a system once dominated by prairie-type grasses is now transitioning to a traditional piedmont forest.

pp. 308-323

Geologic juxtapositions can result in nutrient-poor and shallow ultramafic or serpentinite soils placed adjacent to well developed and nutrient-rich mafic soils. Tree species growing in these soils are likely to employ different mechanisms to cope with the distinct edaphic conditions. The results suggested that the edaphic factor is a strong environmental constraint, forcing unique physiological differences among seedlings of Quercus species, leading to site-specific adaptive characteristics. Such morphological and physiological responses allow for a better understanding of the mechanisms controlling plant–soil associations.

pp. 324-340

Ultramafic rocks and their chemically distinct soil products are generally known to affect vegetation floristics and species productivity. Little is known on how the vegetation characteristics of the Vredefort Dome in South Africa are affected by these rock types, and the present study discloses several species that seem to be associated with ultramafic–mafic intrusions within the dome, as well as geochemically contrasting rock types. Because of their strong relationship with different geological substrates, identified species groups can serve as useful indicators for chemical and mineralogical changes in soil and geology.

pp. 341-352

Algae and cyanoprokaryotes can colonise almost all soil types but little is known about the occurrence of these organisms in South African serpentine soils. We found a unique species assemblage in one of the serpentine sites with high metal concentrations, but the findings are preliminary and the effect of vegetation and climate on the presence of algae should be further investigated.

The relation between vegetation and soil was investigated in a poorly studied ultramafic area in the north Morocco (Beni bousera). The peculiarities of this area are discussed in comparison with adjacent non ultramafic areas. This comparison shows a clear differentiation of vegetation among the plant communities. Preferential or strict serpentinophytes species were recognised but no hyperaccumulator species have yet been found.

Unique flora established on serpentine habitats of Kızıldağ, Konya Province, Turkey is dealt in this paper. This flora is rich in endemic metal hyperaccumulators, particularly nickel, rather unusual and potentially valuable plant resources, therefore, deserves conservation. The Ni-hyperaccumulating species from Turkey are invaluable plant genetic resource for investigations on phytoremediation, phytomining and agromining emerging fields of farming for metals.
