The Adrenocortical Response to Stress in Incubating Magellanic Penguins (Spheniscus magellanicus) [PDF]

The Auk, 1998
Circulating levels of glucocorticoids increase rapidly in response to capture and handling in many vertebrate species, which is indicative of the sensitivity of the hy- pothalamo-pituitary-adrenal axis to a variety of acutely stressful events. We measured cir- culating levels of corticosterone at capture and after 25 min of handling and restraint in ...

Stable Isotope Analysis of New Zealand Fur Seal Vibrissae Shows Deceased Juveniles Were Weaned Early

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 2, June 2026.
The New Zealand fur seal/kekeno (Arctocephalus forsteri, NZFS) is a marine predator native to Aotearoa/New Zealand. Little is known about its fine‐scale dispersal around New Zealand in the nonbreeding season. As an alternative to external marking or electronic tracking, stable isotope analysis was trialed to determine the origin of stranded (deceased ...

Shifting Seas, Changing Diets: Evidence of Temporal Dietary Shifts in Marine Megafauna in Southern Brazil (2017–2023)

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.
ABSTRACT Understanding the dietary dynamics of marine megafauna is essential for interpreting ecological interactions and assessing environmental changes in marine ecosystems. We analysed temporal trends in the diets of eight megafaunal species, comprising marine mammals, seabirds, and sea turtles.

Asymmetry and Asynchrony in Postnatal Growth Patterns of Two Sympatric Species of Antarctic Penguins

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Two sympatric penguin species breeding at Narebski Point, King George Island in West Antarctica, show differences in growth asymmetry between siblings, indicating differences in early life history strategies. Chinstrap Penguin chicks grow less asynchronously, while Gentoo Penguin chicks have stronger asynchrony, suggesting Gentoo Penguins may have more
