Shift in plant-soil interactions along a lakeshore hydrological gradient

Alexandre Buttler, Luca Bragazza, Mathieu Raymond Santonja, Wenjuan Feng

Wetlands occupy the transitional zone between aquatic and terrestrial systems. Hydrological conditions have significant influence on wetland plant communities and soil biogeochemistry. However, our knowledge about plant-soil interactions in wetlands along ...

Seasonal variability of groundwater level effects on the growth of Carex cinerascens in lake wetlands

Alexandre Buttler, Pierre Rémi Mariotte, Luca Bragazza, Mathieu Raymond Santonja, Wenjuan Feng

Groundwater level is crucial for wetland plant growth and reproduction, but the extent of its effect on plant growth can vary along with changed precipitation and temperature at different seasons. In this context, we investigated the effect of two groundwa ...

Occurrence and ecological determinants of the contamination of floodplain wetlands with Klebsiella pneumoniae and pathogenic or antibiotic-resistant Escherichia coli

François Gillet, Charles Pierre Roger Henriot

The survival and multiplication of human pathogenic and antibiotic-resistant bacteria in ecosystems is of increasing concern but has been little explored. Wetlands can be contaminated by water fluxes from rivers and may present environmental conditions lea ...

The ecology and biogeochemistry of stream biofilms

Tom Ian Battin

Streams and rivers form dense networks, shape the Earth's surface and, in their sediments, provide an immensely large surface area for microbial growth. Biofilms dominate microbial life in streams and rivers, drive crucial ecosystem processes and contribut ...

A hydrologic tracer study in a small, natural wetland in the humid tropics of Costa Rica

Growing populations and food demand in the tropics are leading to increased environmental pressures on wetland ecosystems, including a greater reliance on natural wetlands for water quality improvement. Effective assessment of wetland treatment potential r ...

Demodulation of time series highlights impacts of hydrologic drivers on the Everglades ecosystem

Andrea Rinaldo

In the context of climatic uncertainty and potential climatic change, incorporating climatic variability and change in eco-hydrological analysis, as well as understanding the impact of such variability on ecosystems, is of crucial importance. The latter is ...

Observational constraints on the distribution, seasonality, and environmental predictors of North American boreal methane emissions

Jed Oliver Kaplan, Bowen Zhang

Wetlands comprise the single largest global source of atmospheric methane, but current flux estimates disagree in both magnitude and distribution at the continental scale. This study uses atmospheric methane observations over North America from 2007 to 200 ...

Optimizing turbine withdrawal from a tropical reservoir for improved water quality in downstream wetlands

Alfred Johny Wüest, Bernhard Wehrli

Large reservoirs in the tropics act as efficient nutrient traps and often develop hypoxic conditions in the hypolimnion. Both effects may have severe implications for aquatic ecosystems, such as limited primary production in downstream riparian agriculture ...

Signs of critical transition in the Everglades wetlands in response to climate and anthropogenic changes

Andrea Rinaldo

The increasing pressure of climatic change and anthropogenic activities is predicted to have major effects on ecosystems around the world. With their fragility and sensitivity to hydrologic shifts and land-use changes, wetlands are among the most vulnerabl ...

Present state of global wetland extent and wetland methane modelling: conclusions from a model inter-comparison project (WETCHIMP)

Jed Oliver Kaplan

Global wetlands are believed to be climate sensitive, and are the largest natural emitters of methane (CH4). Increased wetland CH4 emissions could act as a positive feedback to future warming. The Wetland and Wetland CH4 Inter-comparison of Models Project ...
