Tissue humidity and pH as important species traits regulating tree methane emissions in floodplain wetland forests

New Phytologist, Volume 248, Issue 4, Page 1713-1727, November 2025.
Summary Despite the increasing number of studies investigating tree methane fluxes, the relationships between tree methane fluxes and species traits remain mostly unexplored. We measured leaf and stem methane fluxes of five tree species (Acer saccharinum, Fraxinus nigra, Ulmus americana, Salix nigra, and Populus spp.) in the floodplain of Lake St ...

Modelling the Spatio‐Temporal Effects of Water Level Control in an Agricultural Collector Ditch Network

Irrigation and Drainage, Volume 74, Issue 4, Page 1717-1729, October 2025.
ABSTRACT The study focused on modelling open channel flow in an agricultural ditch network. The objectives were (1) to set up a computational tool to explore the hydraulic impacts of water level control in a collector ditch network and (2) to test the effects of damming height and ditch flow resistance on the water level and its relation to field ...

Identification and Global Distribution of a Core Microbiome From High‐Arctic Lakes

Environmental Microbiology, Volume 27, Issue 10, October 2025.
Identification of the core microbiome from clear water lakes in the Arctic reveals non‐unique members when compared with a conceptually similar lake from a more temperate region. Biogeographic assignments revealed that the genera from this core were widespread globally within four general habitat categories.

eDNA Metabarcoding to Monitor Fish Communities in a Large River Floodplain

Environmental DNA, Volume 7, Issue 5, September–October 2025.
Comparing eDNA metabarcoding with electrofishing in the Lake St. Pierre floodplain, we found that both methods detected similar dominant species but revealed differences in overall community composition. Each method captured sector‐driven patterns in fish communities, while land use played a weaker role.

Étude préliminaire de recrutement fluvial de l'anguille

Knowledge and Management of Aquatic Ecosystems, 1994
La migration anadrome de l'anguille a pu être étudiée sur une petite rivière bretonne, l'Arguenon. Sur ce cours d'eau, le barrage de la Ville Hatte représente un obstacle infranchissable situé 10 km en amont du barrage estuarien.

The duration of high spring light for understorey plants: Contrasting responses to spatial and temporal temperature variation

Journal of Ecology, Volume 113, Issue 9, Page 2526-2538, September 2025.
Over 7 years, warmer springs were associated with earlier leaf‐out of two temperate forest understorey herbs and of the trees above them, but the effect was stronger for the herbs. This suggests that climate warming will prolong the relatively brief period of high light available to understorey plants in spring, which is a key determinant of their ...

Caractérisation d'une modification éventuelle de la relation pluie-débit en Afrique de l'Ouest : cas du bassin versant du N'zi (Bandama) en Côte d'Ivoire, Thèse de Doctorat, Université de Cocody-Abidjan, Côte d'Ivoire, 210 p.

Physio-Géo, 2010
De nombreuses études sur la variabilité climatique à l'échelle de l'Afrique de l'Ouest et de la Côte d'Ivoire, montrent qu'une tendance à la sécheresse s'est manifestée à partir de la fin de la décennie 1960.
