简介
Common demographic parameters such as survival and fecundity are regularly estimated in freshwater turtles, but large‐scale manipulative and comparative experiments are rare. The resilience of a population to stage‐specific predation is dependent on density‐dependent inversity or compensation. Some species are also more susceptible to predation because of their life‐history strategies. Nest predation by introduced red foxes ( Vulpes vulpes) on Australian freshwater turtles is a major source of mortality, but its full impact has yet to be evaluated. Freshwater turtles are long lived, and a population decline resulting from nest predation by foxes may take a long time to become evident. We evaluated the impact of foxes on the population growth and patterns of survival of two widely distributed Australian freshwater turtles in the Murray River, where nest predation rates have previously been reported at above 95 …
