Matono, Paula; Da Silva, Janine; Bernardo, João; Costa, Ana Manuel; Fragoso, Sonia; Roque, Luisa; Pinheiro, Paulo; Almeida, João; Ilhéu, MariaEste Manual de Boas Práticas foi elaborado no âmbito do Programa LIFE + “Conservação do Saramugo, Anaecypris hispanica, na bacia do Guadiana (Portugal)”, ou LIFE Saramugo (LIFE13 NAT/PT/000786). O Projeto visa salvaguardar a conservação deste peixe nativo e endémico das bacias hidrográficas dos Rios Guadiana e Guadalquivir, que está atualmente “Criticamente em Perigo” em Portugal e incluído no Anexo II e IV da ...
Behavioural interactions between the endangered native fish Saramugo, Anaecypri...
da Silva, Janine; Matono, Paula; Barata, Eduardo; Bernardo, João Manuel; Costa, Ana Manuel; Ilhéu, MariaInvasive species have the potential to impact native fish through interference competition, which is especially concerning for the conservation of the valuable endemic ichtyofauna of the Iberian Peninsula. This study investigated the potential negative effect of the invasive bleak Alburnus alburnus on the behaviour of the critically endangered Iberian saramugo Anaecypris hispanica. The behaviour patterns were a...
Anthropogenic Pressures in Temporary Streams: the importance of environmental d...
Matono, Paula; Bernardo, João Manuel; Costa, Ana Manuel; Ilhéu, MariaMediterranean temporary streams show high spatial and temporal heterogeneity. Native fish species are adapted to this natural variability, but the cumulative effect of natural and anthropogenic disturbances may compromise the stability and persistence of fish assemblages. This study aimed to determine if environmental drivers affect the response of fish assemblages to anthropogenic pressures in temporary stream...

Dispersal and coexistence of two non-native crayfish species (Pacifastacus leni...
Bernardo, João Manuel; Costa, Ana Manuel; Bruxelas, Sofia; Teixeira, AmílcarNE Portugal is one of the most isolated and low populated regions of Western Europe. Recently, two American crayfish species reached this area: signal crayfish Pacifastacus leniusculus coming from Spain and red swamp crayfish Procambarus clarkii in its northward expansion. The dispersion of both species was followed throughout the last decade in river Maçãs (Douro catchment). Our results support the hypothesis ...
