Última Impact of warming on abundance and occurrence of flatfish populations in the Bay of Biscay (France) ArchiMer Hermant, Marie; Lobry, Jeremy; Bonhommeau, Sylvain; Poulard, Jean-charles; Le Pape, Olivier. The aim of the present study was to analyse the influence of warming on flatfish populations in the Bay of Biscay. 17 autumn cruises conducted from 1987 to 2006 over the whole shelf of the Bay of Biscay provided data for the abundance and occurrence of adults for twenty flatfish species. Trends in flatfish abundance were analysed with regard to geographic range of populations and interannual fluctuations in abundance were related to seawater temperature. Results showed significant trends in abundance and occurrence for 55% of the flatfish species in the Bay of Biscay. The response to warming of seawater was correlated to geographic ranges of species. While the abundance of the northern temperate species decreased, that of southern ones increased. Moreover,...

Avulsos de Zool. (São Paulo) Prado,Joyce R.; Percequillo,Alexandre R.. Aegialomys xanthaeolus (Cricetidae: Sigmodontinae) inhabits the arid montane areas of western Ecuador and Peru, and higher elevations in the upper Marañón valley in northern Peru. Some researchers have included this species in broader systematic assessments over the years, but there are no comprehensive studies focusing on intraspecific variation. There are several sources of intraspecific phenotypic variation, including sexual dimorphism and age. These sources may confound the assessment of similarity/dissimilarity among populations, therefore it is essential that non-geographic variation is evaluated before studies on geographical variation and species delimitation are carried out. Here we summarize existing information regarding the geographical... Tipo: Info:eu-repo/semantics/article Palavras-chave: Geographic Distribution; Skull; Ontogeny; Sexual Dimorphism; Morphometrics.
