Are shifts in species distribution triggered by climate change? A swordfish cas...
Erauskin-Extramiana, Maite; Arrizabalaga, Haritz; Cabré, Anna; Coelho, Rui; Rosa, Daniela; Ibaibarriaga, Leire; Chust, GuillemSpecies shifts due to climate change are being recorded and reported worldwide. However, the accurate estimation and causal attribution of species shifts using spatial distribution indicators, such as the center of gravity, is challenging. This is particularly problematic for commercially exploited marine species with data from research surveys, commercial fisheries or other data collection methods that are not...
Functional redundancy and sensitivity of fish assemblages in European rivers, l...
Teichert, Nils; Lepage, Mario; Sagouis, Alban; Borja, Angel; Chust, Guillem; Ferreira, Maria Teresa; Pasquaud, Stéphanie; Schinegger, RafaelaThe impact of species loss on ecosystems functioning depends on the amount of trait similarity between species, i.e. functional redundancy, but it is also influenced by the order in which species are lost. Here we investigated redundancy and sensitivity patterns across fish assemblages in lakes, rivers and estuaries. Several scenarios of species extinction were simulated to determine whether the loss of vulnera...

Living under stressful conditions: Fish life history strategies across environm...
Teichert, Nils; Pasquaud, Stéphanie; Borja, Angel; Chust, Guillem; Uriarte, Ainhize; Lepage, MarioThe life history strategies of fishes can be defined by specific combinations of demographic traits that influence species performances depending on environmental features. Hence, the constraints imposed by the local conditions restrict the range of successful strategies by excluding species poorly adapted. In the present study, we compared the demographic strategies of fish caught in 47 estuaries of the North ...
Uses of Innovative Modeling Tools within the Implementation of the Marine Strat...
Lynam, Christopher P.; Uusitalo, Laura; Patrício, Joana; Piroddi, Chiara; Queirós, Ana M.; Teixeira, Heliana; Rossberg, Axel G.; Sagarminaga, YolandaIn Europe and around the world, the approach to management of the marine environment has developed from the management of single issues (e.g., species and/or pressures) toward holistic Ecosystem Based Management (EBM) that includes aims to maintain biological diversity and protect ecosystem functioning. Within the European Union, this approach is implemented through the Marine Strategy Framework Directive (MSFD...
Dispersal similarly shapes both population genetics and community patterns in t...
Chust, Guillem; Villarino, Ernesto; Chenuil, Anne; Irigoien, Xabier; Bizsel, Nihayet; Bode, Antonio; Broms, Cecilie; Claus, SimonDispersal plays a key role to connect populations and, if limited, is one of the main processes to maintain and generate regional biodiversity. According to neutral theories of molecular evolution and biodiversity, dispersal limitation of propagules and population stochasticity are integral to shaping both genetic and community structure. We conducted a parallel analysis of biological connectivity at genetic an...
