Demography of the critically endangered Balearic shearwater: the impact of fisheries and time to extinction

World-wide, many seabirds are affected by fisheries in opposing ways: as a source of mortality from bycatch, but also by providing discards as a predictable and abundant food resource. This applies to the Balearic shearwater Puffinus mauretanicus, the most endangered European seabird, whose time to extinction was estimated at only ˜40 years a decade ago. Since the previous assessment, new data and more sophisticated demographic modelling have become available, and new fishing policies from the European Union (Common Fisheries Policy, CFP) will apply, posing different scenarios for the viability of the species.

Consecutive cohort effects driven by density-dependence and climate influence early-life survival in a long-lived bird

Conditions during early life, including maternal cohort effects, can influence the future fitness of individuals. This may be particularly true for longdistance migrating birds, because, apart from conditions experienced by cohorts during rearing, conditions during early life in regions far from breeding grounds may also influence their population dynamics.

Colonization in social species: the importance of breeding experience for dispersal in overcoming information barriers

Studying colonisation is crucial to understand metapopulations, evolutionary ecology and species resilience to global change. Unfortunately, few empirical data are available because field monitoring that includes empty patches at large spatiotemporal scales is required. We examine the colonisation dynamics of a long-lived seabird over 34 years in the western Mediterranean by comparing population and individual data from both source colony and the newly-formed colonies.

An evaluation of socioeconomic factors that influence fishers’ discard behaviour in the Greek bottom trawl fishery

A newly introduced regulation renders the discarding of certain commercially important species illegal within the European waters progressively until 2019 (Article 15, EC Regulation 1380/2013). .... In this paper, fishers’ socio-economic behaviour is analyzed in relation to discarding practices under the “discrete choice” framework. Specifically, a variety of socioeconomic attributes, in the form of principal components that may affect the choices of the Greek bottom trawl fishers on three key discards’ drivers are analyzed to identify possible links between these.

Balearic Islands boat seine fisheries: the transparent goby fishery an example of co-management

An economically important, small-scale fishery operates during the winter months in Mallorca. Using a special surrounding net that is hauled over the sand and gravel bottoms of bays at depths reaching 30 m, it primarily targets Aphia minuta and Pseudaphya ferreri, but other goby species and juveniles of the Pagellus spp are also caught. Similar fisheries are operated on the Spanish coast and in Italy.
