The conservation of arboreal marsupials in the montane ash forests of the central highlands of Victoria, south-eastern Australia, VI. The performance of statistical models of the nest tree and habitat requirements of arboreal marsupials applied to new survey data

摘要: Abstract Statistical models are widely used as a tool to provide concise description of data by identifying and quantifying relationships between key explanatory variables. The adequacy the fit such can be gauged various diagnostic procedures. However, performance statistical models, when applied new datasets, yield valuable insights about assumptions that underpin may identify potentially important In this study we describe results field survey was undertaken specifically assess previously developed nest tree habitat requirements arboreal marsupials inhabiting montane ash forests central highlands Victoria, south-eastern Australia. involved comparing logit Poisson regression from surveys at 152 sites completed 1983 1989 with dataset comprised 55 gathered in 1992–1993. Our analyses demonstrated most earlier studies performed reasonably well they were recently collected data. Thus, for two there similarities characteristics trees hollows their occupancy species marsupials. Similar recorded assessments models. Notably, some Leadbeater's possum, Gymnobelideus leadbeateri McCoy, greater congruence than similar comparisons retained linear strips (wildlife corridors). This finding further emphasizes previous observations appears disadvantaged narrow areas habitat.
