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

Efecto de la radiación ultravioleta sobre los ecosistemas acuáticos [PDF]

, 1998
Hasta hace poco tiempo se consideraba que la radiación ultravioleta carecía de importancia como factor ambiental en los ecosistemas acuáticos, ya que se suponía que se absorbía totalmente en los primeros centímetros de la columna de agua.

Can induced drying modulate the response of leaf litter decomposition and fungal diversity to wastewater effluents in permanent streams?

Functional Ecology, Volume 39, Issue 12, Page 3543-3555, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Watercourses are among the most threatened ecosystems globally and face multiple anthropogenic stressors of different origins and intensities that reduce biodiversity and disrupt ecosystem functioning.

The influence of hydrological seasonality and land use and cover on the relationship between dissolved organic carbon and carbon dioxide along a karst‐draining large tropical river

Limnology and Oceanography, Volume 70, Issue 10, Page 2858-2871, October 2025.
Abstract The partial pressure of carbon dioxide (pCO2) in rivers is influenced by carbonate weathering, soil CO2, photosynthesis, and the mineralization of dissolved organic carbon (DOC). In tropical regions, elevated temperatures intensify these processes. However, their seasonal dynamics remain poorly understood in large karst‐draining rivers.

Review of ecological valuation and equivalency analysis methods for assessing temperate nearshore submerged aquatic vegetation

Conservation Biology, Volume 39, Issue 1, February 2025.
Abstract Nearshore seagrass, kelp, and other macroalgae beds (submerged aquatic vegetation [SAV]) are productive and important ecosystems. Mitigating anthropogenic impacts on these habitats requires tools to quantify their ecological value and the debits and credits of impact and mitigation.

Hurricane‐induced changes in mayfly assemblage structure, production and emergence in a tropical island stream Cambios inducidos por los huracanes en la estructura, producción, y emergencia del ensamblaje de Ephemeroptera de una quebrada de isla tropical

Ecological Entomology, Volume 50, Issue 1, Page 201-213, February 2025.
Hurricanes create major disturbances to stream ecosystems by producing large floods and removing riparian vegetation. Understanding their impacts is a priority, as hurricane intensity will increase with global climate change. Hurricane disturbance shifts mayfly assemblages from dominance by Leptophlebiidae before to Baetidae after.
