Programa de doctorado en Oceanografía

Biodiversidad Boa Vista. Conocer y proteger

[ES] El proyecto consiste en crear un libro de fotografías artísticamente atractivo y de calidad divulgativa y científica sobre la isla de Boa Vista para dar a conocer y sensibilizar con imágenes, sobre la cultura, la riqueza y fragilidad de este enclave de biodiversidad en Cabo Verde. La idea para su edición es el crowdfunding a través de la plataforma web VERKAMI

Voluntariado ambiental para la conservación de la Tortuga Boba (Caretta caretta) en la isla de Boa Vista

[ES]Cabo Verde Natura 2000 es una organización sin ánimo de lucro que en colaboración con ADS-Biodiversidad organiza, desde 1998, un voluntariado ambiental para la protección de la población de tortuga boba (Caretta caretta) de Cabo Verde. El 90 % de esta población nidifica en la isla de Boa Vista, donde la ONG tiene su centro de actuación. Cada temporada (de Junio a Octubre) acuden a los campamentos de Cabo Verde Natura 2000 cientos de voluntarios dispuestos a colaborar con la causa y vivir una experiencia única. Buscamos voluntarios para la campaña 2016. hablaremos de la importancia de la conservación de la población de tortugas marinas de Cabo Verde, de las actividades se realizan desde la ONG y de cómo participar.

Abundance and exploitation of loggerhead turtles nesting in Boa Vista Island, Cape Verde: The only substantial rookery in the eastern Atlantic.

[EN] The main nesting area for loggerhead turtles in the eastern Atlantic is in the Cape Verde Islands, largely restricted to the island of Boa Vista. Extensive monitoring demonstrated a globally significant population for the species despite a sustained high level of anthropogenic take of nesting females for local consumption. Through an extensive stratified monitoring program across the island in the seasons 2007-2009, we estimated a total of 13955, 12028 and 19950 clutches in the 3 years, respectively. These values indicate that the mean number of nesting females averaged 3700. Considering that a female breed, on average, every 2.4 years, we estimate that the overall number of adult females in the population during these three seasons was 8900.

Density, nest site characteristics and breeding rates of the osprey (Pandion haliaetus) in the southern limit of its range in the Western Palearctic (Boa Vista, Cape Verde Islands).

[EN] Between 2004 and 2007, we studied density, habitat features and breeding parameters of the osprey (Pandion haliaetus) population in Boa Vista Island (Cape Verde). A total of 79 nest structures were identified, 37 of which were occupied for at least 1 year during the study period. The osprey population ranged between 14 and 18 pairs, and the mean density and distance between neighbouring occupied nests were 2.58 pairs per 100 km2 and 3089 m, respectively. Occupied nests were found to be significantly further from the coastline and roads than unoccupied nests, but the distances from villages were similar.

Rate predation on the nesting of Caretta caretta because of Ocypode cursor in Calheta de Pau beach, Boa Vista Island (Cape Verde Rep.)

[EN] Located in the Cape Verde Archipelago is one of the most important nesting population of Caretta caretta, Boa Vista Island being the principal nesting area. This population has been subject of research since 1998.

Incidental Capture of Loggerhead Turtles (Caretta caretta) on Boa Vista (Cape Verde Islands)

[EN] The sea is one of the major natural resources of the Cape Verde Islands, a small archipelago located 500 kilometers off the coast of Senegal (West Africa). This country consists of ten main islands and several islets, and possesses an Exclusive Economical Zone (EEZ) of about 734 square kilometers and a coastal perimeter of nearly 2000 kilometers. The marine shelf, whose limit is the 200 m isobath, is particularly extensive on the island of Boa Vista (Figure 1). lt is likely that most of the loggerhead turtles (Caretta caretta) that breed in this archipelago are concentrated on this island (López-Jurado et al., 1999).
