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.

Dietary metabarcoding of keystone sardine species reveals the importance of their ichthyoplankton prey in food webs of the Southern Brazilian Bight fisheries

Fisheries Oceanography, Volume 33, Issue 4, July 2024.
Abstract Clupeiform fishes are ecologically and economically important species contributing to industrial and artisanal fisheries worldwide. They represent key links in food webs, influencing the dynamic between trophic levels. The dietary interactions of these species are poorly studied in many regions, yet essential for fisheries management.

Partial migration in Magellanic penguins

Journal of Avian Biology, Volume 2024, Issue 3-4, March/April 2024.
We studied the migration of Magellanic penguins near the southern tip of the breeding distribution, and for the first time found evidence of partial migration for this species within the same colony. Forty‐three percent of the penguins studied stayed within ~ 290 km of the colony (residents), while others went northwards as far as 2000 km. All penguins
