| plastic debris in mediterranean seabirds. | plastic debris is often ingested by marine predators and can cause health disorders and even death. we present the first assessment of plastic ingestion in mediterranean seabirds. we quantified and measured plastics accumulated in the stomach of 171 birds from 9 species accidentally caught by longliners in the western mediterranean from 2003 to 2010. cory's shearwaters (calonectris diomedea) showed the highest occurrence (94%) and large numbers of small plastic particles per affected bird (on av ... | 2013 | 24449923 |
| yelkouan shearwater nest-cavity selection and breeding success. | we describe, for the first time, nest-cavities selected by the mediterranean endemic yelkouan shearwater puffinus yelkouan on french islands, comparing it with the sympatric cory's shearwater calonectris diomedea. by monitoring 179 suitable cavities during four years, we show that yelkouan shearwaters select deeper cavities and with more winding tunnels than those selected by cory's shearwaters or unoccupied cavities. logistic regression modelling indicates that cavities with nest-like character ... | 2007 | 17434114 |
| polymorphic microsatellite markers for the critically endangered balearic shearwater, puffinus mauretanicus. | ten novel polymorphic microsatellite loci were isolated and characterized from the balearic shearwater (puffinus mauretanicus), a critically endangered seabird. the developed loci revealed a relatively low number of alleles per locus, as well as low levels of polymorphism (h(o) = 0.377 ± 0.241). one of the loci appeared to be w-linked. all polymorphic loci were successfully amplified in its closely related species, the yelkouan shearwater (puffinus yelkouan). these microsatellite markers would ... | 2009 | 21564834 |
| yelkouan shearwater puffinus yelkouan presence and behaviour at colonies: not only a moonlight question. | we describe and test the influence of several environmental and biological factors on the presence and activity patterns of the mediterranean endemic yelkouan shearwater puffinus yelkouan at colonies. bird arrival at breeding sites is highly correlated with nautical dusk for moonless or slightly moonlit nightfalls and correlated with moonset when the moon is visible. breeding cycle and wind speed affect both the arrival times and presence at colonies. bird activity also varies throughout the nig ... | 2008 | 18187125 |
| patterns of at-sea behaviour at a hybrid zone between two threatened seabirds. | patterns of behavioural variation and migratory connectivity are important characteristics of populations, particularly at the edges of species distributions, where processes involved in influencing evolutionary trajectories, such as divergence, mutual persistence, and natural hybridization, can occur. here, we focused on two closely related seabird species that breed in the mediterranean: balearic shearwaters (puffinus mauretanicus) and yelkouan shearwaters (puffinus yelkouan). genetic and phen ... | 2019 | 31604997 |
