Environmental and Evolutionary Forces Shaping Penguin Geographic Limits

Journal of Biogeography, Volume 52, Issue 9, September 2025.
ABSTRACT Aim Penguins are seabirds exclusively found in the Southern Hemisphere, with their existence dating back to the late Cretaceous. Despite their exceptional dispersal capabilities, which allow them to inhabit a wide range of environments—from polar regions to temperate zones, and even near the Equator—penguins are absent in the Northern ...

Is What Comes out the Same as What Goes in? A Preliminary Investigation of the Isotopic Impacts of Digestion by Red‐Tailed Hawks (Buteo jamaicensis) and Eurasian Eagle Owls (Bubo bubo)

Ecology and Evolution, Volume 15, Issue 5, May 2025.
Isotope analysis of predator feces and consumed prey remains can be used to non‐invasively track diet and reconstruct past environment and climate conditions. However, one must account for the isotopic difference between diet and feces, as well as the possible influence of digestion on consumed prey tissues.

Balancing ecotourism and wildlife management through a conservation behavior approach

Conservation Science and Practice, Volume 7, Issue 3, March 2025.
We surveyed ecologists, conservationists, and ecotourism professionals to investigate consequences of ecotourism on animal behavior. We highlight four main behavioral themes and solutions for engendering more sustainable ecotourism that mitigates behavioral impacts.

Potential Spatial Mismatches Between Marine Predators and Their Prey in the Southern Hemisphere in Response to Climate Change

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.
