Year-round at-sea distribution and trophic resources partitioning between two s...
Almeida, Nathalie; Ramos, Jaime A.; Rodrigues, Isabel; Santos, Ivo; Pereira, Jorge M.; Matos, Diana M.; Geraldes, Pedro; Melo, Tommy; Paiva, Vítor H.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 ecological guild. Here we studied the foraging ecology of two sympatric species-brown booby (BRBO) Sula leucogaster (breeding) and red-footed boobies (RFBO) Sula sula ...
A significant nesting population of loggerhead turtles at the nature reserve of...
Rocha, Patricia Rendall; Melo, Tommy; Rebelo, Rui; Catry, PauloLoggerhead sea turtles Caretta caretta are globally endangered. The population nesting in Cabo Verde is genetically distinctive and numerically important in a global context. In Cabo Verde, the majority on the nesting takes place on the island of Boavista, but recent work suggests that other important nesting sites may exist. Santa Luzia is the only large uninhabited island in Cabo Verde. In this study, beach s...
The Foraging Ecology of the Endangered Cape Verde Shearwater, a Sentinel Specie...
Paiva, Vitor H.; Geraldes, Pedro; Rodrigues, Isabel; Melo, Tommy; Melo, José; Ramos, Jaime A.Large Marine Ecosystems such as the Canary Current system off West Africa sustains high abundance of small pelagic prey, which attracts marine predators. Seabirds are top predators often used as biodiversity surrogates and sentinel species of the marine ecosystem health, thus frequently informing marine conservation planning. This study presents the first data on the spatial (GPS-loggers) and trophic (stable is...
