Factors regulating epilithic biofilm carbon cycling and release with nutrient enrichment in headwatexchange occurred in the two most nutrient-poor streams. Further, this ratio was best predicted by newC. suggesting increased relative activity of some algae relates to reduced algal–bacterial C exchange within these biofilms. Net release of DOC represented 2–45% of NPP with greatest release of DOC

The physico-chemical habitat template for periphyton in alpine glacial streams under a changing clirse sediment transport were not paralleled by an increase in periphyton biomass. In the non-glacial streams, seasonal periphyton patterns were similar to those of glacial streams, but biomass was significantly higher. Glacier recession from climate change may shift water sources in glacier streams a

Various biological indicators have been applied during several surveys on AMEW, allowing the characterisation of (i) the structure and diversity of biofilm communities [community level finger printing (CLFP)

Discharge and the response of biofilms to metal exposure in Mediterranean rivers,While Cd seems to proceed from diffuse sources being washed by surface runoff, Zn, Pb, and As may proceed from either diffuse or point-sources in the different river sites investigated. The relevance of diffuse metal pollution in the area of study indicates that polluted landfills runoff might be an

Global change and food webs in running waters,ad to seemingly counterintuitive responses to perturbations that cannot be predicted from the traditional focus of studying individual species in isolation. In this review, we highlight the need for developing new network-based approaches to understand and predict the consequences of global change i
