Ecology of Freshwater Fish, Volume 34, Issue 4, October 2025.ABSTRACT Environmental and biological factors strongly shape fish diets, yet little is known about such influences in flooded Karst Dolines of the Neotropical region. This study examined the diet of Deuterodon luetkenii and assessed its temporal and ontogenetic variation in Lagoa Misteriosa, a karstic lagoon. Fish were sampled bimonthly over 1 year and

Freshwater Biology, Volume 70, Issue 10, October 2025.ABSTRACT Stream ecosystem functioning and community structure are influenced by local and catchment land use. In mosaic landscapes, agricultural activities can also affect leaf breakdown and detritivore assemblages in downstream forest reaches. We evaluated the combined effects of upstream deforestation and the input of a nonnative crop species on leaf

Ecological Entomology, Volume 50, Issue 4, Page 595-608, August 2025.The two most diverse beetle families, Staphylinidae and Curculionidae (black arrows), have fewer studies of diversity and elevation than expected, while the Carabidae and Scarabaeidae (brown arrows) are overstudied. Dung beetle (Scarabaeidae) phylogenetic and taxonomic diversity decreases with elevation along tropical and temperate elevational ...

Ecohydrology, Volume 18, Issue 5, July‐August 2025.ABSTRACT Mountain streams exhibit hydrogeomorphological heterogeneity, which is further intensified by the presence of hydraulic infrastructure. Despite extensive research on the influence of hydrological conditions and flow regulation on ecology, there is a notable absence of holistic studies investigating stream dynamics from both geomorphologic and ...

Freshwater Biology, Volume 70, Issue 7, July 2025.ABSTRACT Aquatic insects are an abundant, yet declining, taxonomically heterogeneous group with special importance in both aquatic and terrestrial ecosystems. Accurate estimations of insect biomass during their aquatic life stages are essential to advance our fundamental knowledge about insects, their roles in ecosystems, and their vulnerability to ...

Aquatic habitat response to small dam removal demonstrates recovery in three years
Ecosphere, Volume 16, Issue 6, June 2025.Abstract Dams disrupt river networks by interrupting longitudinal transport of sediment and nutrients and obstructing the movement of aquatic organisms. Increasingly, water resource managers are looking for dam removal as a solution to restore connectivity and improve aquatic habitats, water quality, and fish passage.

Limnology and Oceanography Letters, Volume 10, Issue 3, Page 371-380, June 2025.Abstract The Cofán communities rely on the Cofán Bermejo Ecological Reserve for their survival and cultural practices. Due to the rugged and inaccessible topography of the reserve in the Northern Ecuadorian Amazon region, limited biomonitoring and ecological characterization studies of the ecosystem health have been conducted.
