The role of web-based chemical communication in the mating and foraging strategies of the orb web spider Argiope keyserlingi
Chemical communication is critical in shaping the interactions of individual animals, both within and between species. Pheromones (species-specific chemical signals) occur in all species and arguably contribute to more ...
Defining the master regulator of urethral closure in mouse
Hypospadias is the ectopic placement of the urethral opening on the underside of the penis and is one of the most common developmental abnormalities in humans, occurring in approximately 1 in every 125 live male births. ...
Triple jeopardy in the tropics: assessing extinction risk in Australia's freshwater biodiversity hotspot
Freshwaters are the most degraded and imperiled ecosystem globally. Despite this high vulnerability, conservation efforts in freshwaters often lag behind those in terrestrial and marine ecosystems. In Australia this is ...
Cognitive bias as an indicator of emotional state and welfare in captive zebrafish
Concerns regarding animal welfare are ultimately predicated on the assumption that animals can experience subjective feelings, which are the prerequisite to experiencing suffering, pain and pleasure. Assessing the subjective ...
Defining the role of endogenous estrogen in penile urethral development
Hypospadias, the ectopic placement of the urethral meatus along the ventral aspect of the penis, is one of the most common birth defects in boys. The prevalence of hypospadias has increased in recent decades, a phenomenon ...
Effects of fungicides on Australian amphipods and organic matter breakdown in aquatic environments
Fungicides are used widely in agriculture to control fungal diseases and increase crop yield. After application, fungicides may be transported off site via air, soil and water to ground and surface waters therefore have ...
The behavioural resistance and response of Atlantic salmon to the ectoparasite Lepeophtheirus salmonis
Behavioural responses of hosts to parasites or risk of infection can drive the success of parasites. Behaviour is a form of resistance or defence that is prevalent in many host-parasite systems, and can occur over fine- ...
Comparative phylogeography and diversity of Australian Monsoonal Tropics lizards
Tropical savannah biomes cover ~20% of the world’s landmass, however the biodiversity encompassed within these environments and the underlying processes that have shaped it remain poorly understood. Recent increased research ...
Evolution and biogeography of Australian tropical freshwater fishes
Australia’s freshwater fish fauna is the most depauperate of any continent (256 formally recognised species), although endemism is exceptionally high (74%), largely due to its arid climate and history of isolation from ...
Contaminant exposure affects gene expression markers in the cysteine metabolism of Chironomus tepperi
In ecotoxicology, organisms are often exposed to contaminated water or sediment to investigate the toxicity of these aspects of the environment. The results of these exposures are intended to predict responses in the ...
