Methane (CH₄) plays an important role in atmospheric chemistry and is a powerful greenhouse gas, responsible for a third of current radiative forcing. Open surface waters (lakes, rivers and reservoirs) and wetlands represent a major source of CH₄ on a global scale. However, their contribution remains uncertain in terms of total contribution (25-45%...
The roles of Asgard archaea in eukaryogenesis and marine biogeochemical cycles are well studied, yet their contributions in soil ecosystems remain unknown. Of particular interest are Asgard archaeal contributions to methane cycling in wetland soils. To investigate this, we reconstructed two complete genomes for soil-associated Atabeyarchaeia, a new...
Seasonal floodplains in the Amazon basin are important sources of methane (CH4), while upland forests are known for their sink capacity. Climate change effects, including shifts in rainfall patterns and rising temperatures, may alter the functionality of soil microbial communities, leading to uncertain changes in CH4 cycling dynamics. To investigat...
Mangroves' ability to store carbon (C) has long been recognized, but little is known about whether planted mangroves can store C as efficiently as naturally established (i.e., intact) stands and in which time frame. Through Bayesian logistic models compiled from 40 years of data and built from 684 planted mangrove stands worldwide, we found that bi...
Climate changes significantly impact greenhouse gas emissions from wetland soil. Specifically, wetland soil may be exposed to oxygen (O2) during droughts, or to sulfate (SO42-) as a result of sea level rise. How these stressors - separately and together - impact microbial food webs driving carbon cycling in the wetlands is still not understood. To ...
Les activités paludières du sud Bretagne sont nées il y a de cela plusieurs siècles, profitant d’une géomorphologie du trait de côte adaptée à ce type d’activités. En effet, le littoral de cette région est parcouru par de nombreux rentrants, qui, couplés à une marégraphie particulière, ont permis l’établissement d’une activité d’extraction du sel s...
Sous l'Ancien Régime, la Vallée Scarpe-Escaut formait un espace multifonctionnel axé sur l'humide. Les populations y avaient développé des pratiques agropastorales spécifiques et variées, la transformant en un territoire d'eau largement multifonctionnel et productif. Les inondations constituaient un élément d'une hydraulique maîtrisée caractéristiq...
Heron colonies are dynamic components of wetlands. Therefore, their systematic monitoring is important for the management of both birds and wetlands. During the period 1988–2018, we counted breeding pairs of seven colonial breeding heron species at 65 colonies across 37 wetlands in Greece. We considered as annual variables of a population: (a) year...

Coastal wetlands are transitional ecosystems between land and sea. Participants of citizen science programs have detected frequent floods in wetlands, as well as small pools that appear and then disappear. Considering that it is not clear whether their main hydrologic drivers are of marine or continental origin, we studied the El Culebrón wetland l...

Objective. Hg was quantified in the dorsal muscle of the 11 species of fish most consumed in San Marcos, located in the region of La Mojana. Materials and methods. Dorsal muscle samples were taken from the fish species. T-Hg concentrations were quantified using cold vapor atomic absorption spectrophotometry (CVAAS). Results. The species with the hi...
