Abstract:
Biomass of phytoplankton in large rivers may be maintained or even increased by inputs from hydraulic "dead zones". In some eutrophic rivers, dead zones can increase water retention time sufficiently for the development of algal concentrations substantially higher than in the main channel. "Seeding" of the main channel may then occur through the interchange of water between dead zones and the main channel. The objective of this thesis was to investigate the role of dead zones in the development of phytoplankton along the moderately eutrophic Rideau River. In the first chapter, I compare the su

Submerged macrophytes are known to influence the structure and function of lake ecosystems. Despite their importance, long term monitoring records of macrophytes are rare and thus relatively little is know regarding how human activities have altered macrophyte abundance in lakes.

Abstract:
A usina hidrelétrica Luis Eduardo Magalhães situada no Estado do Tocantins entre os municípios de Miracema do Tocantis e Lajeado é uma das maiores obras civis no país construída com recursos da iniciativa privada. A barragem apresenta 2.100 m de comprimento e vertedouros com 14 vãos e capacidade para escoar 49.870 m3/s de água. O reservatório encontra-se em área de cerrado com pouca fitomassa, baixo tempo de retenção (24 dias) e morfometria pouco complexa. A usina apresenta um circuito de geração com cinco casas de força e capacidade para abrigar cinco turbinas tipo Kaplan, com potência nomina

Abstract:
Photodegradation rates of methylmercury (MeHg) were measured in water samples from several lakes in the Lake Berthelot region in Quebec in order to investigate the impact of drainage basin logging and associated changes in dissolved organic carbon (DOC) concentrations on MeHg levels in lake water. The lakes were selected on the basis of the amount of logging that had previously taken place in the drainage basin, and on DOC levels which were correspondingly higher in logged lakes due to increased runoff. Lakes DA9 and DF9 had DOC concentrations of 12.3 and 20.9 ppm, respectively and were design

Abstract:
The microbial metacommunity of the Pyrenees mountain range has never been studied at the regional level. In this PhD thesis, the main goal is to describe the taxonomic diversity and reveal the ecological processes (biotic and abiotic) behind the spatial distribution and heterogeneity of surface communities of alpine lakes. With a sampling of more than 300 lakes during summer of 2011 and high-througput sequencing of ribosomal markers (16S and 18S rRNA), we analized the microbial profiles of archaeal, bacterial and eukaryotic communities. We highlighted the discovery and description of novel and

Abstract:
Os reservatórios de água são sistemas artificiais rasos destinados à múltiplos usos. Estes usos associados as atividades desenvolvidas na bacia hidrográfica acarretam impactos nos corpos d\'água, principalmente nos sedimentos, os quais representam um depósito e também uma fonte de contaminantes sobre determinadas condições ambientais. O tipo de construção dos reservatórios é bastante relevante no contexto de poluição e contaminação. Teoricamente os reservatórios construídos em cascata tendem a apresentar uma melhora na qualidade das águas e sedimentos ao longo da construção, pois o reservatóri
