The amazing diversity we see in Australian animal developed early and has slowed considerably in the last 10 million years, say Ian Brennan and Scott Keogh from the ANU Research School of Biology.
I will tell you about Australia's most diverse snake genus, their relationships with one another, how they got to where they are, and what their morphological and ecological variation can tell us about their evolutionary history and their future.
A fundamental challenge in animal ecology research lies in the ability to understand the factors that shape the evolution and plasticity of behaviours, life histories, and population dynamics of organisms.
Common wall lizards are one of the most widespread and frequently encountered reptiles in Europe. They span the entire continent from Spain through to Turkey and have even managed to find themselves introduced into areas outside their native range (e.g., the UK).
The extraordinary diversity of life has evolved alongside major changes in Earth’s climate and geography and understanding this link is one of the key goals of evolutionary biology.
Human-crocodile conflict is becoming a conservation challenge worldwide. The saltwater crocodile (Crocodylus porosus) is the largest (>6 m total length, >1000kg) and most aggressive living crocodilian species being responsible for increasing attacks on people and domestic animals in many countries.
