Article
Light‐level geolocators are popular bio‐logging tools, with advantageous sizes, longevity, and affordability. Biologists tracking seabirds often presume geolocator spatial accuracies between 186‐202 km from previously‐innovative, yet taxonomically, spatially, and computationally limited, studies. Using recently developed methods, we investigated wh...

Migratory marine species cross political borders and enter the high seas, where the lack of an effective global management framework for biodiversity leaves them vulnerable to threats. Here, we combine 10,108 tracks from 5775 individual birds at 87 sites with data on breeding population sizes to estimate the relative year-round importance of nation...
Article
Sexual segregation in foraging strategies has been little studied in marine species with slight Sexual Size Dimorphism (SSD), particularly regarding the role of environmental conditions and fishery activities. Sexual differences in fishery attendance are of particular concern because uneven mortality associated with bycatch may exacerbate impacts i...
Article
Niche partitioning among different age, breeding status or sex classes allows resource use to be maximized while reducing intraspecific competition. Individual specialization marks the finest scale of niche partitioning where, within a species, individuals differ in their realized niches. Despite having important implications in ecology, evolution...
Article
Marine birds have been hypothesized to be underreported victims of harmful algal blooms (HABs). Toxic blooms of Pseudo-nitzschia spp., the primary amnesic toxin producer microalgae, domoic acid (DA) are known to cause massive mortalities of coastal seabirds and marine mammals around the world. However, these fatalities are only detected when birds...

Project
The environmental sustainability and the conservation of biodiversity is one of the major challenges of the Spanish society. In particular, our project seeks (1) Identifying main foraging, resting and wintering areas and their corridors in four pelagic seabirds (Cory’s, Scopoli’s and Cape Verde shearwaters and Bulwer’s petrel) throughout the year; (2) Evaluating the spatial consistency of these areas across several temporal scales; (3) Identifying the environmental variables driving seasonal and inter-annual changes in these areas, and exploring their suitability as early predictors of the seabird distribution; (4) Assessing spatiotemporal overlap and interactions between pelagic seabirds and the different types of fisheries operating in the Mediterranean and the Atlantic.
