Fire is an important management tool for both hazard reduction burning and maintenance of biodiversity. The impact of time since last fire on fauna is an important factor to understand as land managers often aim for prescribed burning regimes with specific fire-free intervals. However, our current understanding of the impact of time since last fire on fauna(More)
Fire is frequently used for land management purposes and may be crucial for effective control of invasive non-native plants. Nevertheless, fire modifies environments and may affect nontarget native biodiversity, which can cause conflicts for conservation managers. Native Australian reptiles avoid habitat invaded by the alien plant rubber vine (Cryptostegia(More)
Caudal autotomy is a common defense mechanism in lizards, where the animal may lose part or all of its tail to escape entrapment. Lizards show an immense variety in the degree of investment in a tail (i.e., length) across species, with tails of some species up to three or four times body length (snout-vent length [SVL]). Additionally, body size and form(More)
We investigated demographic responses of the common brushtail possum Trichosurus vulpecula, a medium-sized arboreal marsupial, after a prescribed fuel reduction burn on Magnetic Island, tropical north Queensland, Australia. Possums were live-trapped every month for 14 months before the fire and 11 months after the fire in both the burnt and unburnt areas;(More)
