Recent genetic analyses have revealed evidence for the existence of two distinct lineages of Little Penguin (genus Eudyptula), one endemic to New Zealand (E. minor), and the other widespread along the coasts of Australia and south-east New Zeala[...]

Population limitation is the outcome of cumulative and synergistic processes that act on species over multiple spatial scales. Tree cavity dependent animals are good case studies for exploring processes that potentially limit populations across [...]

Understanding and monitoring biological communities requires accurate species inventories using reliable and efficient methods of detection. Automated recorders deployed in the field have the potential to substantially reduce observer bias and t[...]

Blue Petrels (Halobaena caerulea) are known to breed at seven locations in the Southern Ocean. Population estimates have been made recently for the two major breeding sites, but accurate estimates are lacking for the remaining locations. We used[...]

The Common Diving Petrel (Pelecanoides urinatrix) is an abundant seabird species within New Zealand waters. Breeding in this species occurs from late July through to December and adults are thought to remain in New Zealand waters during non-bree[...]

The foraging and perching behaviours of urban commensal birds are well studied but disproportionately focused on green spaces (e.g. parks, backyards) rather than inner city urban sites. The relationship between building use and foraging was exam[...]

Divergence is the first phase of speciation and is commonly thought to occur more readily in allopatric populations. Subspecies are populations that are divergent but generally retain the capacity to interbreed should they come into contact. Two[...]

Allee effects occur when survival or reproductive success declines with decreasing population size or density. Species most severely impacted by Allee effects may be the very species for which these effects will be hardest to detect and overcome[...]
