Age effects on Nazca booby foraging performance are largely constant across variation in the marine environment: Results from a 5-year study in Galápagos. [PDF]
Ecol Evol, 2023 Foraging performance affects the nutritional resources available for reproduction and survival, influenced by the environment and an animal's individual factors, like age. We evaluated how foraging traits, measured across 5 years, changed with age, environmental variation, and their interaction in Nazca boobies, a tropical, pelagic seabird in Galápagos.

Environmental and human factors shape the trophic ecology of a widespread marine predator. [PDF]
J Anim EcolOur study reveals how environmental factors and fishing pressure influence swordfish diet, highlighting trophic shifts under future climate scenarios. We provide a novel framework to strengthen our ability to plan for and manage the redistribution of species under global change ensuring that the energetic needs of predators are met.

Rapid Ocean Warming Drives Sexually Divergent Habitat Use in a Threatened Predatory Marine Ectotherm. [PDF]
Glob Chang BiolHow ectothermic, mobile marine predators are responding to climate change is uncertain due to lack of species‐specific data, which can mask the true impact of this threat. We investigate the impact of environmental conditions and thermal extremes on the behavior and distribution of angelsharks, a highly threatened elasmobranch of global conservation ...

Indirect effects of African megaherbivore conservation on bat diversity in the world's oldest desert
Conservation Biology, Volume 36, Issue 2, April 2022., 2022 Abstract In extreme environments, temperature and precipitation are often the main forces responsible for structuring ecological communities and species distributions. The role of biotic interactions is typically thought to be minimal. By clustering around rare and isolated features, like surface water, however, effects of herbivory by desert‐dwelling ...

Validación de imágenes satelitales de temperatura superficial del mar mediante observaciones in situ
Boletín Científico CIOH, 2003 La temperatura superficial del mar, medida in situ durante el crucero oceanográfico "Caribe-2003" a bordo del ARC "Malpelo" entre el mes de marzo y abril del 2003 en aguas de la Guajira, se compara con mediciones remotas de radiómetros de alta resolución producidas por los satélites NOAA-16-y NOAA-17.
