New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1164-1186, December 2025.ABSTRACT The New Zealand fur seal/kekeno (Arctocephalus forsteri, NZFS) is native to Aotearoa/New Zealand. Its original range included the entire coast of mainland New Zealand, and offshore and subantarctic islands. The NZFS has gradually recolonised much of its former range after being almost extirpated by hunting, however, little is known about ...

Krill-feeding behaviour in a chinstrap penguin compared to fish-eating in Magellanic penguins: a pilot study. [PDF]
, 2004 Inferring feeding activities from undulations in diving depth profiles is widespread in studies of foraging marine predators. This idea, however, has rarely been tested because of practical difficulties in obtaining an independent estimate of feeding ...

New Zealand Journal of Zoology, Volume 52, Issue 5, Page 537-550, December 2025.ABSTRACT Recreational activities such as jet boating have the potential to disturb native birds that rely on braided river habitats. To examine whether jet boating affects levels of glucocorticoid hormones, which can increase in animals under stress, we compared concentrations of corticosterone in the faeces of nesting black‐backed gulls (Larus ...

Bayesian total evidence dating reveals the recent crown radiation of penguins [PDF]
, 2016 The total-evidence approach to divergence-time dating uses molecular and morphological data from extant and fossil species to infer phylogenetic relationships, species divergence times, and macroevolutionary parameters in a single coherent framework ...

PLoS ONE, 2020 Although many studies have documented the effects of demographic bottlenecks on the genetic diversity of natural populations, there is conflicting evidence of the roles that genetic drift and selection may play in driving changes in genetic variation at ...

Patterns in tern trophic diversity in a region experiencing rapid climate change
Ecosphere, Volume 16, Issue 10, October 2025.Abstract Foraging plasticity provides a mechanism for long‐lived species to adapt to rapidly changing environments. When shifts in food availability occur, individual variation in plasticity can lead to an increase in within‐species trophic diversity. We tested for drivers of trophic diversity in Arctic tern (Sterna paradisaea) and common tern (Sterna ...

Frontiers in Marine Science, 2022 Most seabirds forage far from land, making them hard to observe when foraging. Satellite tracking of seabirds shows where they come into conflict with human uses of the ocean, and whether they use protected areas.
