Freshwater ecosystems along river floodplains host among the greatest biodiversity on Earth and are known to respond anthropic pressure. For water impounded systems, resilience changes in natural flow regime is believed be bidirectional. Whether such prevents system from returning pristine conditions after reverse as yet unclear, though widely documented. In this work, we show that temporal irr...

The landscape pattern of vegetation communities is of fundamental importance to ecologists and biogeographers because it establishes the biotic template upon which largescale ecological processes occur. Landscape vegetation patterns within boreal forests are thought to be driven strongly by abiotic disturbance processes (i.e. fire in uplands, floods in floodplains) coupled with the extremely co...

Microbial community assembly and microbial functions are affected by a number of different but coupled drivers such as local habitat characteristics, dispersal rates, and species interactions. In groundwater systems, hydrological flow can introduce spatial structure and directional dependencies among these drivers. We examined the importance of hydrology in structuring bacterial communities and...

Wetlands cover approximately 6% of the Earth's surface. They are frequently found at the interface between terrestrial and aquatic ecosystems and are strongly dependent on the water cycle. For this reason, wetlands are extremely vulnerable to the effects of climate change. Mangroves and floodplain ecosystems are some of the most important environments for the Amazonian population, as a source o...

The objective of this study is to determine spatio-temporal variations of water volume over inundated areas located in large river basins using combined observations from the Synthetic Aperture Radar (SAR) onboard the Japanese Earth Resources Satellite (JERS1), the Topex/Poseidon (T/P) altimetry satellite, and in-situ hydrographic stations. Ultimately, the goal is to quantify the role of floodp...
