In this study, we analysed the viability of seabird populations, specifically the European shag, after the invasion of the American mink. In the last decade the shags at Cíes islands, the southernmost archipelago of the Park, experienced a population collapse in parallel with a similar reduction in its level of heterozygosity. Data from marked indi...

In this study I analized changes in population-density and age structure for a population of the threatened fresh-water pearl mussel in a 10 years period

Loss of genetic diversity is thought to lead to increased risk of extinction in endangered populations due to decreasing fitness of homozygous individuals. Here, we evaluated the presence of inbreeding depression in a long-lived seabird, the European shag (Phalacrocorax aristotelis), after a severe decline in population size by nearly 70%. During t...

Large oil spills are dramatic perturbations on marine ecosystems, and seabirds are one of the worst affected organisms in such events. It has been argued that oil spills may have important long-term consequences on marine organisms, but supporting evidence remains scarce. The European shag (Phalacrocorax aristotelis) was strongly impacted at popula...

Climate influences the dynamics of natural populations by direct effects over habitat quality but also modulating the phenotypic responses of organisms' life-history traits. These responses may be different in males and females, particularly in dimorphic species, due to sex-specific requirements or constraints. Here, in a coastal seabird, the Europ...
Technical Report

Census of breeding populations of European shags and Yellow-legged gulls in the National Park of the Atlantic islands of Galicia (NW Spain) and establishment of monitoring areas. Effects of mink predation on European shag populations. Population trend in the yellow-legged gull and relationship with landfill closures. Gull nesting and dune flora.

Marine censuses of the four species of small procellariforms that breed in the Canary Islands formed part of the fieldwork within the framework of the Project Life Important Areas for Seabirds (IBAs) in Spain and which was carried out by SEO/BirdLife. In total, more than 180 hours of census work was carried out in Canary Islands waters, both aboard...

The results of the censuses of the European Storm-petrel Hydrobates pelagicus carried out within the project Life Important areas for seabirds (IBA) in Spain and carried out by SEO/BirdLife have enabled knowing the distribution and abundance of this species in Spanish peninsular waters after more than 900 hours of censusing. The species shows a pre...

The observations of Madeiran Storm-petrel Oceanodroma castro in waters of northwestern Spain (Galician Bank) during July and, especially, in September are, with the exception of the four accepted records by the Spanish Rarities Committee (CR/SEO), the first in Spanish Peninsular waters. These observations were the result of pelagic embarcations off...

In 2003, immediately following the Prestige oil spill in Galicia, Spain, we studied the population trends and reproductive performance of European shags (Phalacrocorax aristotelis) at oiled and unoiled colonies. This bird is an important member of the nearshore marine community, breeding in the area affected by the Prestige oil spill. The European...
