Evaluación del impacto de las estructuras de defensa costera sobre la biota marina. Efectos a nivel local, regional y trófico
(2021-02-08)
El escenario actual de cambio global (ej. aumento del nivel del mar y de los eventos climáticos extremos) y el incremento de la población humana en zonas costeras (con el consecuente aumento en la explotación de recursos ...
Tesis Doctoral
Interactions between non-native parrot species their recipient environments
(2020-12-18)
Biological invasions are amongst critical causes of biodiversity loss around the world, although interactions between invasive species, native biota and recipient environment are mostly unknown. Their identification may ...

Impact of Noise on Early Development and Hearing in Zebrafish (Danio rerio)
(2021-11-09)
Fishes are highly specialized in extracting ecologically relevant information from their diverse acoustic habitats since early developmental stages. The zebrafish (Danio rerio) is a valuable and well-stablished vertebrate ...

Spatio-temporal dynamic of the early life stages of fishassemblagesin the Guadalquivir estuary. Responses to anthropic and natural disturbances
(2021-11-18)
Estuarine environments are regions at the interface of riverine and marine systems and are critical habitats for many resident and migratory species. They may support high abundances of organisms due to their high productivity, ...

Evolution of the environmental niche of amphibians in Western Mediterranean and conservation implications. Integrating modelling, environmental physiology and conservation traits
(2020-12-02)
Amphibians are one of the most environment dependent organism, being limited by physiological traits at two main life stages (larvae and adult). In addition, the Western Mediterranean region, our study area, has an old ...

The evolutionary dynamics of laying date in the pied flycatcher Ficedula hypoleuca
(2021-12-17)
Current global warming is unequivocally impacting biodiversity at an unprecedent rates. Such negative impact can be quantified on species distribution and diversity, but understanding biodiversity loss can only be fully ...
