Conservation biology of the largest Australian freshwater tortoise, the broad-shelled tortoise, Chelodina expansa - rare and endangered or cryptic and secure?

墨累河是一条高度管理的河流，流量由集水区和改道控制。水资源开发、生境改变和引进物种的综合影响多种多样，包括一些鱼类和无脊椎动物的灭绝以及许多其他物种种群的减少。澳大利亚最大的海龟，宽壳龟，是一种高级消费者，被认为对这些变化特别敏感。我们将使用非破坏性技术的创新组合来调查下默里的这一物种的保护生物学，在那里它被认为是罕见的，它的生物学几乎是未知的，以告知保护管理和恢复计划

The Murray is a highly managed river, with flows controlled by catchments and diversions. The combined impacts of water resource development, habitat modification and introduced species are astonishingly diverse, and include extinctions of some fish and invertebrates and depression of populations of many other species. Australia's largest chelid turtle, the broad-shelled turtle, is a high-level consumer thought to be particularly sensitive to these changes. We will use an innovative combination of non-destructive technologies to investigate the conservation biology of this species in the Lower Murray, where it is regarded as rare and where its biology is virtually unknown to inform conservation management and restoration initiatives
