Drought reduces the value of both artificial and natural wetlands for gulls breeding in the Mediterranean region

Journal of Applied Ecology, Volume 63, Issue 3, March 2026.
The importance of artificial wetlands for waterbird conservation can be easily overestimated from count data alone. The value of extensive fish ponds as a breeding habitat depends on maintaining the availability of natural marshes as a foraging habitat. This requires reducing impacts from groundwater extraction. Given recent abandonment of aquaculture,

Optimizing Total Suspended Solids Mitigation in a Data‐Limited Watershed: A Network‐Based Advection–Reaction Model Applied to the Canal del Dique, Colombia

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Total Suspended Solids (TSS) significantly degrade water quality by reducing light penetration and oxygen availability, while facilitating the transport of toxic contaminants. Managing TSS in watersheds requires an understanding of both hydrological connectivity and pollutant dynamics; however, these efforts are significantly constrained by ...

Constitutive immune function variation across the non‐breeding season in an extreme long‐distance migrant

Journal of Avian Biology, Volume 2025, Issue 5, September 2025.
Migratory animals often display remarkable adaptations in order to successfully complete their journeys. While there is substantial evidence on immunomodulation during breeding and at stopover sites en route, the immune status of migratory birds upon reaching their non‐breeding grounds and throughout this stationary season remains poorly understood ...
