Wintering Together: Do Migrants Impact Residents? A Literature Review

Ecology and Evolution, Volume 15, Issue 2, February 2025.
This review examines the overlooked impacts of interspecific competition on resident tropical birds during the overwintering period, highlighting the need for a deeper understanding of their interactions with migratory species. By evaluating the literature through the lens of competition theory, we identify critical gaps in knowledge and suggest that ...

Island restoration to rebuild seabird populations and amplify coral reef functioning

Conservation Biology, Volume 39, Issue 1, February 2025.
Abstract Mobile organisms like seabirds can provide important nutrient flows between ecosystems, but this connectivity has been interrupted by the degradation of island ecosystems. Island restoration (via invasive species eradications and the restoration of native vegetation) can reestablish seabird populations and their nutrient transfers between ...

Sex‐Specific Variation in Foraging Behavior is Related to Telomere Length in a Long‐Lived Seabird

Ecology and Evolution, Volume 14, Issue 12, December 2024.
Foraging during breeding is energetically demanding, intimately linked to breeding investment, and possibly constrained by individual condition. Telomere length, the protective nucleoproteins located at the ends of the chromosomes, is considered a trait reflecting somatic maintenance and individual quality. We found that brown booby females with longer
