The Biodiversity of the Mediterranean Sea: Estimates, Patterns, and Threats
Overall spatial and temporal patterns of species diversity and major changes and threats were assessed, and temporal trends indicated that overexploitation and habitat loss have been the main human drivers of historical changes in biodiversity.

It is argued here that predictable anthropogenic food subsidies (PAFS) provided historically by humans to animals has shaped many communities and ecosystems as the authors see them nowadays and comparison of subsidised and non-subsidised ecosystems can help predict changes in diversity and the related ecosystem services that have suffered the impact of other global change agents.
Trans‐equatorial migration and mixing in the wintering areas of a pelagic seabird
Despite increasing interest in long-distance migration, the wintering areas, migration corridors, and population mix in winter quarters of most pelagic marine predators are unknown. Here, we present…
Potential consequences of discard reform for seabird communities
The potential for both negative and positive impacts of discard reforms for seabirds are considered, with particular focus on the EU, and recommendations for ongoing research and conservation are proposed.
Modelling demography and extinction risk in the endangered Balearic shearwater
Several demographic parameters of Balearic shearwater were estimated and used to model extinction probabilities for the species, which is an endemic seabird confined to a Mediterranean archipelago, and played a more important role than environmental stochasticity in population growth rate.
Colony Size Selection Determines Adult Survival and Dispersal Preferences: Allee Effects in a Colonial Bird
Adult survival and dispersal in relation to colony size within a long‐term monitored population of lesser kestrels (Falco naumanni) is investigated and Nest predation probability decreases with colony size, and adult survival is predicted to show the same trend.
Competition between the yellow-legged gull Larus cachinnans and Audouin's gull Larus audouinii associated with commercial fishing vessels: the influence of season and fishing fleet
The lower representation of Audouin's gull in other breeding areas in the Mediterranean, as well as the less important fishing fleets in these areas, would probably reduce the attractiveness of trawlers for this species, even during the breeding season.

Testing the Goodness of Supplementary Feeding to Enhance Population Viability in an Endangered Vulture
Although AFS are not effective to save bearded vultures from an expected population decline, they delay population extinction and can be a useful tool for prolonging population viability while combating illegal and indirect poisoning.
Exploitation of trawler discards by breeding seabirds in the north-western Mediterranean: differences between the Ebro Delta and the Balearic Islands areas
Local trawler fisheries operate around the seabird colonies of the Ebro Delta and Majorca. The use made of the discards produced by thisfishery by scavenging breeding seabirds was examined from 1992…
