▪ Abstract It has recently been argued that the paradox of helping behavior in birds has been
solved. This optimism may be premature. I argue that there is no obvious dichotomy …

A comprehensive review of the hundreds of bird species that have become extinct over the
last 1,000 years of habitat degradation, over-hunting and rat introduction. Extinct Birds has …

The rate of adaptive evolution, the contribution of selection to genetic changes that increase
mean fitness, is determined by the additive genetic variance in individual relative fitness. To …

Summary 1 Adaptive management involves the development of predictive models, strategic
manipulation of management actions to gain information, and subsequent updating of the …

Aim We studied dynamics of four populations of New Zealand forest birds for 5–9 years after
reintroduction to islands. We primarily aimed to predict whether these populations were …

Pioneering work by Quinn and Burrows in the late 1930s led to successful artificial
insemination (AI) programs in the domestic poultry industry. A variety of species specific …

We analysed mortality and behaviour of hihi, an endangered New Zealand honeyeater, in
the first three months after translocation to 135 ha Mokoia island. Our aims were to …

Group-living species show a diversity of social organization, from simple mated pairs to
complex communities of interdependent individuals performing specialized tasks. The …

The maintenance of genetic diversity is thought to be fundamental for the conservation of
threatened species. It is therefore important to understand how genetic diversity is affected …

Attempts to conserve threatened species by establishing new populations via reintroduction
are controversial. Theory predicts that genetic bottlenecks result in increased mating …
