Spatio‐Temporal Dynamics of Asian Clams in Two Mediterranean Canals

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT The rapid spread of the non‐native invasive Asian clam (Corbicula spp.) has been linked to the catastrophic decline of native freshwater mussel assemblages in Europe and North and South America. This study evaluates the spatio‐temporal dynamics and shell size structure of the Asian clam within two Mediterranean canals: Canal Imperial de Aragón

Ecology of declining populations of gray foxes (Urocyon cinereoargenteus) in Indiana, USA Ecología de las poblaciones en declive de zorros grises (Urocyon cinereoargenteus) en Indiana, EE.UU.

open access: yesWildlife Monographs, Volume 226, Issue 1, September 2026.
We estimated seasonal space use, cover selection, and resource selection; evaluated gene flow and potential genetic barriers; and assessed cause‐specific survival rates and reproduction of radiomarked gray foxes in Indiana, USA. Our results provide evidence that gray foxes in Indiana are an edge species with relatively large home ranges, relatively low

Farm‐Scale Recharge Pits for Improving Local Groundwater Availability: Insights From a Hardrock Watershed in Rajasthan, India

open access: yesWorld Water Policy, Volume 12, Issue 3, August 2026.
ABSTRACT Groundwater depletion is a major challenge in semiarid, hard‐rock regions where irrigation demands often exceed natural recharge. This study evaluates the effectiveness of farm‐scale recharge pits as a local, supplementary, and community‐managed groundwater recharge solution in the Dharta catchment of Rajasthan, India. Alongside check dams and

The Essence of Crisis Decision‐Making: Saving Ravenna During the 2023 Floods

open access: yesRisk, Hazards &Crisis in Public Policy, Volume 17, Issue 2, June 2026.
ABSTRACT This article explores decision‐making processes in crisis situations by proposing an interpretive framework grounded in multiple criteria of rationality. Crises, characterized by uncertainty, urgency, and ethical dilemmas, require critical choices that go beyond standard procedures.

Spatial Patterns and Controlling Factors of River Flow Intermittency in Africa

open access: yesWater Resources Research, Volume 62, Issue 6, June 2026.
Abstract Understanding river flow intermittency remains a major challenge in data‐scarce regions such as Africa. This study presents the first high‐resolution, four‐class intermittency map of African rivers using a sequential modeling approach based on Random Forest. A binary model (BC‐UNS) distinguishes perennial from non‐perennial reaches across 15.5

Beyond the Metrics: Context‐Aware Calibration for Better Drain Flow Modelling

open access: yesIrrigation and Drainage, Volume 75, Issue 2, Page 659-668, April 2026.
ABSTRACT Robust hydrological and water quality modelling is essential for advancing the understanding and management of engineered agricultural subsurface drainage systems. Achieving credible model output hinges on calibration strategies that are both rigorous and context sensitive. At the field scale, accurately capturing the dynamics of nutrient load

Farmer‐Led Strategies for Water Conservation in the Urmia Lake Basin, Iran

open access: yesIrrigation and Drainage, Volume 75, Issue 2, Page 840-855, April 2026.
ABSTRACT This study examines the urgent issues of water scarcity and limited farmer livelihoods in the Urmia Lake basin. To address these challenges, we apply the Governance, Autonomy, Integration, and Needs orientation (GAIN) methodology. Our participatory approach revealed that farmers prioritised actionable measures for water management, yield ...

Subglacial drainage processes at a High Arctic polythermal valley glacier [PDF]

open access: yes, 2005
Dye-tracer experiments undertaken over two summer melt seasons at polythermal John Evans Glacier, Ellesmere Island, Canada, were designed to investigate the character of the subglacial drainage system and its evolution over a melt season. In both summers,

RELATIONS PLANTE/SOL/CLIMAT Connaître le sol : nouveaux enjeux pour la gestion des territoires ruraux

open access: yesOléagineux, Corps gras, Lipides, 2000
Dans son acception commune, le mot sol désigne de façon souvent indissociable l’espace d’un territoire et la terre qui le recouvre. Cet héritage culturel d’une époque encore proche où l’association territoire-espace rural-agriculture relevait de l ...
