Hidden Life of the Eastern Longneck

Hidden Life of the Eastern Longneck

Possibly our most well-studied turtle, yet mark-recapture, radio-tracking, behavioural studies, and molecular studies are yielding many surprises on its secret terrestrial sojourns. We now know that this species spends an extraordinary amount of time on land, navigating by the sun, conserving water through terrestrial aestivation and episodic movement associated with rain, that it can survive and thrive in urban systems given the right combination of conditions, and that it comprises a single species across a wide range in eastern Australia with little genetic diversification.

Basic Ecology

What do they eat? Growth and Reproduction Over-wintering in the nest Sex determination in the lab Sex determination in the wild Sex chromosomes

Movements

Life on land Coping with the cycles of wet and dry Wetland connectivity and turtles Water balance on land

Life in Suburbia

Suburbs: Danger or drought refugia? Life in the suburbs during drought Life in the suburbs when drought breaks

Management

What turtles tell us about wetland mgmt What is the impact of fences?
