... to be affected by this disease. Here we present an example of a chytrid related mortality event within an apparently healthy population of this species. The individuals were found to be carrying chytrid and we suggest that this was the proximal cause of mortality. Monitoring was conducted across Sydney Olympic...

... into a food source from elsewhere. The “natural” longevity of flying-foxes and low reproductive rate of only one offspring per female per year reflects the environment in which these bats evolved - one in which they suffered a low annual mortality and could afford a low reproductive rate. We show...

In testing the claims against the evidence, age-specific fecundity, demographic sensitivity, and age structure of M. giganteus populations are quantified. The hypothesis of Arnold et al .

... to ensure long-term persistence. This may require some novel approaches to habitat restoration to achieve. The habitat quality of all connecting corridors must be enhanced to reduce mortality during dispersal. Edge effects such as tree die-back are also likely to reduce the available cover of habitat over...

Even Australia's most abundant and widespread species has declined by up to 91% in some populations. Here I use population...

We propose a shift toward “normalising” flying-foxes, in which they are portrayed as interesting species and a natural part of our highly esteemed biodiversity. This has somewhat already begun...
