Habitat selection and post-release movement of reintroduced brown treecreeper individuals in restored temperate woodland.

It is essential to choose suitable habitat when reintroducing a species into its former range. Habitat quality may influence an individual's dispersal decisions and also ultimately where they choose to settle. We examined whether variation in habitat quality (quantified by the level of ground vegetation cover and the installation of nest boxes) influenced the movement, habitat choice and survival of a reintroduced bird species.

Animal movement in dynamic landscapes: interaction between behavioural strategies and resource distributions.

Most ecological and evolutionary processes are thought to critically depend on dispersal and individual movement but there is little empirical information on the movement strategies used by animals to find resources. In particular, it is unclear whether behavioural variation exists at all scales, or whether behavioural decisions are primarily made at small spatial scales and thus broad-scale patterns of movement simply reflect underlying resource distributions. We evaluated animal movement responses to variable resource distributions using the grey teal (Anas gracilis) in agricultural and desert landscapes in Australia as a model system.

Positive effects of helpers on reproductive success in the brown treecreeper and the general importance of future benefits.

1. Numerous studies of cooperatively breeding species have tested for effects of helpers on reproductive success to evaluate hypotheses for the evolution of cooperation, but relatively few have used experimental or statistical approaches that control for the confounding effects of breeder and territory quality. 2.

Dispersal range analysis: quantifying individual variation in dispersal behaviour.

A complete understanding of animal dispersal requires knowledge not only of its consequences at population and community levels, but also of the behavioural decisions made by dispersing individuals. Recent theoretical work has emphasised the importance of this dispersal process, particularly the phase in which individuals search the landscape for breeding opportunities. However, empirical advances are currently hampered by a lack of tools for quantifying these dispersal search tactics.
