There are no national data on Australian roadkill and the wildlife carers who rehabilitate the resultant animal orphans. This research produces a conservative estimate of mammalian roadkill, quantifies the financial and physical input of carers and explores the emotional implications of caring. In the face of growing demand and diminishing recruitment rates, wildlife carers need more support at State and Federal level if the public service they provide is not to be compromised.

Understanding differences in habitat use and survival of female greater sage-grouse across different reproductive states may help optimise conservation efforts of these iconic birds. Brood-rearing and broodless females used different micro- and macro-habitats, and broodless females had higher summer survival. Adult female survival is critical for persistence of sage-grouse populations, suggesting that conservation efforts should focus on conserving habitats for both brood-rearing and broodless females.

Southern brown bandicoots (eastern subspecies), a nationally endangered marsupial, were reintroduced into an unfenced, predator-managed environment in south-eastern Australia. Factors influencing survival and establishment were investigated, with results revealing habitat preferences and sex-biased dispersal. Future translocations of southern brown bandicoots should consider habitat suitability and potentially larger spatial requirements of males to facilitate successful re-establishment.

One of the challenges is to determine population demography that generate the post-initial irruption of a herbivore population. We investigated annual survival rates of sika deer, Japan and found the survival maintained at a high level. We suggest robust survival of adult females against food limitation might contribute to the maintenance of a high-density sika deer population in the post-initial irruption.

New Zealand falcons breed in plantation forests where 1080 poison operations are regularly conducted, but risks of secondary poisoning and causes of mortality of falcons are not well documented. We studied falcon survival during 1080 operations and found that identifiable mortalities were attributable to depredation by introduced mammals but not by 1080 poisoning. The risk to adult falcons from 1080 secondary poisoning is likely low, but whether this is also true for juveniles requires further study.

Records show that sleepy cod have invaded countless streams and waterholes in Cooper Creek, Lake Eyre Basin, within the last decade. This study documents their transport, establishment, colonisation and integration throughout the catchment, and shows that they have the potential to outcompete native fish species in refugial waterholes. Achieving greater awareness of the potential impacts of introducing non-native species is an important first step towards preserving the native fish fauna of the Lake Eyre Basin.

Citizen science data offers a cost-effective method to help assist in monitoring biodiversity trends within urban greenspaces. We compared two types of citizen science data to assess their applicability in monitoring avian biodiversity trends in a large urban greenspace in Sydney, Australia. We found that eBird data provided higher biodiversity estimates than structured surveys conducted by experienced birdwatchers, suggesting that eBird data may provide a useful tool for land managers interested in monitoring avian communities in urban greenspaces.

Artificial refuges or cover boards are a popular method to survey and monitor herpetofauna, however, detection rates of arboreal species are often low. We tested a non-destructive, passive method of sampling arboreal reptiles using artificial bark covers consisting of closed-cell foam and we found significantly higher detection rates of the arboreal southern marbled gecko under these covers than beneath terrestrial refuges. Artificial bark covers may provide a cost-effective method for procuring threatened arboreal gecko species, and for use in long-term ecological monitoring programs.
