Inland waters are amongst the most diverse and impacted ecosystems globally, and they host many endangered taxa. Cyprinodontiforms are at the forefront of endangered freshwater fishes in Europe, with more than 80% of the ...
En el marc d'un projecte més ampli sobre la comunitat de peixos de la conca lacustre de Banyoles, s'ha estudiat la distribució espacial de les diferents espècies així com l'ús que aquestes fan de l'hàbitat. El poblament ...
Before 1910, the fish assemblage of Banyoles Lake (Catalonia, Spain) consisted of: eel (Anguilla anguilla), Mediterranean barbel (Barbus meridionalis), freshwater blenny (Bennius fluviatilis), three-spined stickleback ...
L'objectiu d'aquesta tesi és aportar les primeres dades sobre l'ecologia del silur (Silurus glanis) introduït a la Península Ibèrica i estimar els seu impacte ecològic sobre la biota nativa. Es van mostrejar les comunitats ...
L'objectiu d'aquesta tesi és de'explorar alguns aspectes de l'impacte humà sobre les poblacions de peixos i altres components dels ecosistemes fluvials Mediterranis de Catalunya. Es va mostrar com els peixos del Riu Llobregat ...
The eastern mosquitofish (Gambusia holbrooki) is one of the most widely distributed and invasive inland fish. It is known that it has not been established in northern Europe or upstream of rivers, where the temperature is ...
Fresh waters are among the most biodiverse ecosystems globally but, at the same time, also the most threatened. Serious threats to freshwater ecosystems are, for example, habitat alteration, invasive alien species and ...
Man-made wetlands are often created to compensate for the loss or degradation of natural wetlands, but little is known about the processes taking place in these artificial environments, especially at the community level. ...
Exploited marine fish species with an affinity for cold waters inhabiting close to the warmer edge of their distribution area are exposed to stress caused by fishing and climate change. Three case studies of “cold water ...
This thesis aims to contribute to the understanding of the invasive success of two invasive fishes (Gambusia affinis and G. holbrooki). We reviewed four Internet databases and the literature to clarify their introduction ...
Small pelagic fish play an important ecological role mainly due to their contribution in transferring energy from low to higher trophic levels. Likewise, the capture of these species is in many cases an important nutritional ...
