Article
Full-text available
The use of biometrics in studies of migratory connectivity is still relatively infrequent in Europe. This is partly due to the fact that biometrics is a less accurate tool when compared to ringing recovery data, or such techniques as stable isotope analyses, use of geolocators or satellite telemetry. Combination with one of these (recovery data) al...

The Balearic shearwater Puffinus mauretanicus is the most threatened seabird in Europe. Several recent research and conservation programmes from different countries (Spain, Portugal, France, UK and Ireland), using various methodologies such as colony monitoring, at-sea surveys, tracking and coastal censuses, brought new information about the popula...

Feather mites (Arachnida: Acari: Astigmata) feed mainly on secretions of the uropygial gland of birds. Here, we use analyses corrected for phylogeny and body size to show that there is a positive correlation between the size of this gland and mite abundance in passerine birds at an interspecific level during the breeding season, suggesting that the...

Shearwaters and petrels (hereafter petrels) are highly adapted seabirds that occur across all the world’s oceans. Petrels are a threatened seabird group comprising 124 species. They have bet-hedging life histories typified by extended chick rearing periods, low fecundity, high adult survival, strong philopatry, monogamy and long-term mate fidelity...

Full-text available
High numbers of seabirds are killed annually worldwide in longline fisheries. In the Mediterranean, this mortality is seriously affecting the viability of seabird populations, in particular of the three endemic shearwaters. Even so, there is currently no specific seabird mitigation requirements for the longline fleet operating in this area. From 20...
Article
Hundreds of thousands of seabirds die annually as a result of being bycaught in longline fisheries, and these rates are unsustainable for many seabird populations worldwide. To understand effects at the population level, it is essential to assess sex- and age-biased mortalities, since uneven mortalities may exacerbate bycatch impacts. In the Medite...
Technical Report
Full-text available
The accidental capture of seabirds and other marine animals in fishing gear is referred to as ‘bycatch’. Globally, bycatch is known to be one of the most significant threats to seabirds (Croxall et al., 2012). An estimated 700,000 birds are killed globally each year between the long-line and gillnet fisheries (Žydelis et al., 2013; Anderson et al.,...
Article
Full-text available
Bycatch mortality in longline fisheries is considered the main threat at sea for numerous seabird species. These incidental catches occur worldwide, but mortality levels are mainly determined by the specific traits of the fishery operating in each area and the feeding behaviour and local abundance of seabirds. In the Mediterranean, demersal artisan...
Article
Full-text available
Fisheries provide an abundant and predictable food source for many pelagic seabirds through discards, but also pose a major threat to them through bycatch, threatening their populations worldwide. The reform of the European Common Fisheries Policy (CFP), which intends to ban discards through the landing obligation of all catches, may force seabirds...
Book
Full-text available
This first issue of The State of Mediterranean and Black Sea Fisheries is a comprehensive review of the status and trends of fisheries in the Mediterranean and Black Sea. It includes eight chapters, separated in two parts: a first part on the status and trends of Mediterranean and Black Sea fisheries under different aspects such as fleet, catches,...
Conference Paper
Fisheries and seabirds are intimately associated as both exploit the same productive areas. Some seabirds take advantage of fishery discards, mostly generated by trawlers, as a supplementary foraging resource, changing their foraging strategies linked to this predictable food. Thus it is expected that any change in fishing practices will have impor...
Article
Full-text available
Understanding why host species differ so much in symbiont loads and how this depends on ecological host and symbiont traits is a major issue in the ecology of symbiosis. A first step in this inquiry is to know whether observed differences among host species are species-specific traits or more related with host-symbiont environmental conditions. Her...

Feather mites are arthropods that live on or in the feathers on birds, and are among the commonest avian ectosymbionts. However, the nature of the ecological interaction between feather mites and birds remains unclear, some studies reporting negative effects of feather mites on their hosts and others reporting positive or no effects. Here we use a...
