Ecosphere, Volume 16, Issue 2, February 2025.Abstract Pygoscelis penguins interact with both terrestrial and marine environments, especially during the austral summer when they raise their chicks. Accessible ice‐free ground spaces serve as locations for penguins to build colonies and successfully raise chicks while the surrounding marine environment serves as the foraging grounds for adult birds.

Parental Quality and Selection on Egg Size in the Magellanic Penguin [PDF]
Evolution, 1990 We examined the relative contributions of egg size and parental quality to hatching success, fledging success, and chick growth in the Magellanic penguin (Spheniscus magellanicus) be exchanging clutches between nests to reduce the covariation between egg and parental factors.

Global Change Biology, Volume 31, Issue 2, February 2025.Global change is reshaping marine habitats, altering predator–prey interactions and food web dynamics. Using Boosted Regression Trees, we assess habitat suitability shifts for crustaceans, fish, penguins, and pinnipeds across three Southern Hemisphere regions from 1850 to 2100 under two climate scenarios.

Breeding Partners Have Dissimilar Foraging Strategies in a Long‐Lived Arctic Seabird
Ecology and Evolution, Volume 15, Issue 1, January 2025.In long‐lived species with biparental care, such as the thick‐billed murre, coordination of foraging strategies between mates may be crucial for raising offspring. This study found that breeding partners had dissimilar foraging behaviors, such as trip distance and dive numbers, compared to randomized pairs, yet they were more similar in wing length ...
