Island restoration to rebuild seabird populations and amplify coral reef functioning

open access: yesConservation 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

open access: yesEcology 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

Simulating drifting fish aggregating device trajectories to identify potential interactions with endangered sea turtles

open access: yesConservation Biology, Volume 38, Issue 6, December 2024.
Abstract Purse‐seine fishers using drifting fish aggregating devices (dFADs), mainly built with bamboo, plastic buoys, and plastic netting, to aggregate and catch tropical tuna, deploy 46,000–65,000 dFADs per year in the Pacific Ocean. Some of the major concerns associated with this widespread fishing device are potential entanglement of sea turtles ...

Evaluating drivers of recent large whale strandings on the East Coast of the United States

open access: yesConservation Biology, Volume 38, Issue 6, December 2024.
Abstract Anthropogenic stressors threaten large whales globally. Effective management requires an understanding of where, when, and why threats are occurring. Strandings data provide key information on geographic hotspots of risk and the relative importance of various threats.

Scouts vs. usurpers: alternative foraging strategies facilitate coexistence between neotropical Cathartid vultures

open access: yesIbis, Volume 166, Issue 4, Page 1368-1383, October 2024.
Understanding how diverse assemblages of scavengers can coexist on shared ecological resources is a fundamental challenge in community ecology. However, current approaches typically focus on behaviour at carcass provisioning sites, missing how important differences in movement behaviour and foraging strategies can facilitate sympatric species ...
