Inter-relationships between benthic macroinvertebrates and habitat types in Broke Inlet, south-western Australia. Report to the Ernest Hodgkin Trust for Estuary Education and Research, September 2008 [PDF]

, 2008
The benthic macroinvertebrate fauna of Broke Inlet, a seasonally-open estuary located in the South coast of Western Australia was sampled seasonally between spring 2007 and autumn 2008 at 20 nearshore sites throughout the estuary. These sites were chosen

Wildfire Ash Alters Freshwater Crustacean Behavior: Disentangling the Contributions of Suspended Macroparticles and Ash‐Induced Alkalinization

Environmental Toxicology, EarlyView.
ABSTRACT Climate change and anthropogenic ignitions are intensifying wildfire frequency worldwide, elevating the risk of freshwater contamination by ash. In water, dissolved ash releases ions and other toxic constituents that increase pH and alter physicochemical conditions, while suspended ash particles may impose mechanical stress, disrupt behavior ...

Movement and Space Use Patterns of the Beale's Eyed Turtle (Sacalia bealei) Suggest Sensitivity to Environmental Changes and Poaching 比氏眼斑龟 (Sacalia bealei) 的活动与空间利用模式揭示其对环境变化及盗猎的敏感性

Wildlife Letters, EarlyView.
Using radiotelemetry, we found that the movement and home range of the endangered Sacalia bealei varied significantly across reproductive classes and seasons, with males exhibiting greater movement than females during wet and mating seasons. The species exhibits strong aquatic dependence, favoring deep pools interspaced among riffle‐pool sequences ...

Effects of Roscovitine and Serum Starvation on the Viability and G0/G1 Synchronization in Somatic Cells from the Antillean Manatee (Trichechus manatus manatus, Linnaeus 1758)

Zoo Biology, EarlyView.
ABSTRACT The success of nuclear reprogramming techniques, including the G0/G1 synchronization of somatic cells, depends on species‐specific optimization. While roscovitine and serum starvation have been successfully applied in domestic and wild terrestrial mammals, their use in aquatic mammals remains poorly investigated.

Changes in benthic ecosystem properties and functions across sedimentary gradients in estuaries [PDF]

, 2014
In estuaries, sediment properties dominate the inhabiting flora and fauna and their role in energy flows and nutrient cycling. Whilst sediment transport is a natural, key process, human intervention in estuaries and their catchments has altered the ...

Ecological scale mediates nonlinear relationships of animal nutrient excretion with dissolved organic matter

Journal of Animal Ecology, EarlyView.
We show that nutrient excretion by vertebrates and invertebrates varies nonlinearly with dissolved organic matter concentration and composition and by taxonomic rank, with stronger patterns at the individual compared to the community level. Our findings highlight the importance of examining animal‐mediated nutrient cycling across taxa and ecological ...

Rapid loss, and slow recovery, of coral reef structural complexity resulting from a prolonged marine heatwave

Journal of Animal Ecology, EarlyView.
Using Structure‐from‐Motion photogrammetry in a longitudinal study, we show that although coral reef habitat complexity had declined significantly by the end of the most prolonged tropical marine heatwave on record, no further losses were detected and 3 years later the reef had begun to recover this critical ecosystem function.

Population characteristics and predation rates of the dominant soft-bodied and durophagous predators on temperate intertidal shores

Royal Society Open Science
Substantial research exists on predation and its ecology. Most research has focused on durophagous fishes, brachyuran crabs, and lobsters. Data are lacking, however, on soft-bodied predators like anemones, and their contribution to overall levels of ...

Evidence of parental care as a newly identified reproductive isolating barrier

Journal of Animal Ecology, EarlyView.
Behavioural variation can contribute to reproductive isolation and can be an important driver of speciation. Here, we show that a previously undescribed mechanism, parental care, can function as a postzygotic reproductive isolating barrier when dysregulated in hybrids.

Survival under stress : benthic foraminiferal patterns and Cenozoic biotic crises [PDF]

, 2000
A principal conclusion of this thesis is, that benthic foraminifera are excellent recorders of paleoenvironments and paleoenvironmental change. Insight in their community structure, and changes in this through time, is still increasing and will add to
