The position of the Gulf Stream influences waterbird brood numbers in a Mediterranean wetland (Albuferas de Adra, Spain)

摘要: espanolLos humedales son ecosistemas complejos caracterizados por la alternancia de estados estables a traves cambios catastroficos. En Albuferas Adra (Almeria, Espana) variabilidad interanual en las condiciones meteorologicas primaverales constituye un factor clave el control entre aguas turbias y elevada biomasa fitoplanctonica fases claras. estudios previos demostramos que esta tiene efectos sobre comunidad aves acuaticas del humedal, desarrolla mayor abundancia numero nidadas los anos ocurren este articulo se analiza teleconexion posicion Corriente Golfo, fenomeno oceanico oscilatorio gran escala afecta fachada atlantica europea, meteorologica dicho ecosistema. Los resultados sugieren desplazamiento hacia Sur Golfo induce inestabilidad zona estudio, lo favorece ocurrencia claras reproduccion acuaticas. Por contrario, desplazamientos Norte corriente oceanica asocian con estables, menor humedal. La latitudinal significativamente al grupos especialistas como fochas, somormujos patos buceadores, mientras no encontro relacion significativa grupo generalista ubiquista nadadores. Finalmente, discuten posibles implicaciones para gestion conservacion avifauna acuatica. EnglishWetlands constitute complex ecosystems where different stable states alternate through catastrophic regime shifts. It is known that the inter-annual variation in spring weather conditions constitutes key for shifts between phytoplankton-dominated turbid and clear water phases Adra, Mediterranean coastal wetland. In previous studies we demonstrated this alternation of equilibrium has an effect on waterbirds, which show higher abundance brood production years characterised by occurrence phases. paper examine teleconnection Gulf Stream position, large-scale oscillating phenomena influencing West Europe, variability waterbird numbers such ecosystem. Our results suggest when moves towards south unstable meteorological prevail region, favouring productivity waterbirds within wetland By contrast, northern displacements oceanic current are associated with weather, lower broods. The position significantly influenced reproduction specialist coots, grebes diving ducks, while relation generalist ubiquitous dabbling ducks was found. Potential implications management waterfowl conservation noted.
