Sex‐Specific Variation in Foraging Behavior is Related to Telomere Length in a Long‐Lived Seabird [PDF]
Ecology and EvolutionForaging during breeding is a demanding activity linked to breeding investment and possibly constrained by individual quality. Telomere length, the protective nucleoproteins located at the ends of the chromosomes, is considered a trait reflecting somatic

Toxoplasma gondii antibodies in tropical seabirds from the Rocas Atoll Biological Reserve, Brazil [PDF]
Revista Brasileira de Parasitologia VeterináriaToxoplasma gondii is a coccidian that infects almost all warm-blooded animals, including birds. Rocas Atoll Biological Reserve, located in the northeast of Brazil, is the only atoll in the South Atlantic, and home to the largest population of seabirds in

Hematological and biochemical reference intervals for populations of seabird species from an Archipelago in Rio de Janeiro, Brazil [PDF]
Frontiers in Veterinary ScienceIntroductionEstablishing reliable hematological and biochemical reference intervals for seabirds is essential for health assessment, rehabilitation, and conservation programs. However, baseline physiological data for these animals remain scarce.

Year-round at-sea distribution and trophic resources partitioning between two sympatric Sulids in the tropical Atlantic. [PDF]
PLoS ONE, 2021 In the oligotrophic tropical marine environment resources are usually more patchily distributed and less abundant to top predators. Thus, spatial and trophic competition can emerge, especially between related seabird species belonging to the same ...

PIQUERO PARDO (SULA LEUCOGASTER) EN EL PERÚ:
Biotempo, 2018 Se documenta nuevos registros del piquero pardo (Sula leucogaster) en el Perú en las islas Guañape, Lobos de Afuera, Macabí y Mazorca, y en Punta Coles. En la primera, el individuo observado corresponde a la subespecie S. l. brewsteri, ampliando su rango de dispersión 3800 km al sur de su zona de reproducción más cercana. En las cuatro áreas restantes,

Ecotoxicology and Environmental contamination, 2023 Seabirds are important bioindicators of environmental quality as their feathers contain records of metal concentration. Among the metals, mercury (Hg) is toxic, causing damage to the organism even in small concentrations.

Survival of Brown Boobies (Sula Leucogaster) at Johnston Atoll: A Long-Term Study [PDF]
The Auk, 2003 AbstractSurvival of Brown Boobies (Sula leucogaster) at Johnston Atoll was examined over a 17-year period using capture-mark-recapture analysis. Annual adult survival was estimated to be 0.90 ± 0.01 (SE). Variation in survival did not correspond to either local environmental fluctuation or more widespread disturbances associated with El Niño-Southern ...

Foraging behaviour and diet of Brown boobies Sula leucogaster from Tinhosas Islands, Gulf of Guinea [PDF]
Marine Biology, 2021 Seabirds are a highly threatened group, yet the foraging ecology of several species remains poorly understood. Brown boobies breed in all oceans in the tropical region and are common across their range.
