Exploring ecohydrology through the lens of local fishers in the Bolivian Amazon
Ecosphere, Volume 17, Issue 4, April 2026.Abstract The natural flow regimes of Andean‐Amazon tributaries play a vital role in sustaining their rich biodiversity and productive local fisheries, but ongoing and proposed alteration of river flow regimes by large dams threatens to negatively impact river ecosystems. Despite its importance, our understanding of how hydrologic variability influences

People and Nature, Volume 8, Issue 3, Page 782-796, March 2026.Abstract Hydropower dams regulate water flows for millions of downstream inhabitants worldwide, altering water availability. Under a changing climate, flow control is often framed technically and politically as being essential for reducing drought and flood risks. However, it can also disrupt ecological flows, impact livelihoods and erode environmental

Earth's Future, Volume 14, Issue 3, March 2026.Abstract Tropical Cyclones (TCs) affecting southeastern Africa are poorly understood, due to limited focused research and challenges in modeling TCs. Higher resolution climate models have potential to provide more reliable projections. In this paper, we analyze the latest global high‐resolution simulations (“HighResMIP”), to evaluate what these models ...

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 ...
