... to these impacts due to specialised habitat requirements. Data collected over the past 15 years relating to vertebrate road mortality and trapping and tracking of small mammals, possums, herpetofauna and invertebrates confirm that many rainforest species suffer edge, linear barrier and disturbance impacts...

... fauna include either a lack of habitat specialisation or a habitat preference for moist environments, high fecundity, a lack of dietary specialisation, and small size. In contrast, a habitat specialisation for sandstone environments (other than caves), stenophagy, low fecundity and large size combined...

... (environmental) factors. The latter include history and geography while poor dispersal capability is typically important amongst the former. Oceanic islands, seamounts and specialised deep-sea habitats, such as hot vents and cold seeps, often have significant numbers of narrow-range taxa. Low levels of narrow...

... with particular sets of habitat attributes. Estimated Sooty and Barking Owl territories in the Mountain Ash Eucalyptus regnans forests of the Central Highlands and the cypress pine Callitris spp-ironbark Eucalyptus spp forests and woodlands of the Pilliga Scrub were concentrated in areas with abundant tree...

... over water, feeding predominantly on aquatic prey items and selecting roosts close (<500m) to permanent water. These traits are broadly representative of all trawling bats and reflect convergence of the group on common, specialised behaviours. Such convergence places trawling bats at risk of very...
