Feeding behaviour of Barbus Bocagei assessed under a spatio-temporal approach IPB - Escola Superior Agrária
Collares-Pereira, M.J.; Martins, M.J.; Pires, A.M.; Geraldes, Ana Maria; Coelho, M.M..
The feeding behaviour of Barbus bocagei was assessed in a lowland system by a two years survey Of two contrasting sites also talking into account, for the first time diurnal changes of fish diet and benthos availability.

Régime alimentaire et croissance du barbeau iberique Barbus bocagei dans la reviere Sorraia (Portugal) IPB - Escola Superior Agrária
Geraldes, Ana Maria; Coelho, M.M.; Collares-Pereira, M.J..
Le barbeau ibérique Barbus bocagei est l’une des espèces les plus représentatives de l’icthyofaune de la rivière Sorraia (Bassin du fleuve Tejo). L’objectif de cette étude est de déterminer 1) les variations spatiales du régime alimentaire et de croissance linéaire de cette espèce entre différentes stations du sous-bassin de la Sorraia et 2) les variations de ces paramètres sur l’échelle temporelle dans deux de ces stations.

Riparian ecotones and spatial variation of fish assemblages in Portuguese lowland streams IPB - Escola Superior Agrária
Collares-Pereira, M.J.; Geraldes, Ana Maria; Magalhães, M.F.; Coelho, M.M..
The first results of a long-term study on the role of riparian ecotones on the population and community dynamics of Iberian stream fish are presented and discussed . Riparian and macrophyte cover, bank slope and depth were among the most important variables affecting fish distribution . In general small fish favoured shallow areas with high macrophyte cover, whereas large fish dominated in deep areas with a high riparian cover . Slight spatial changes in terrestrial prey use were found suggesting a minor role for this resource during autumn . Finally, no significant spatial differences were found for linear growth, although some differences were obtained for the condition factor
