Ingestion of nylon threads by Gerreidae while using a tropical estuary as foraging grounds [PDF]

Aquatic Biology, 2012
The ingestion of plastic fragments by 3 species of Gerreidae (Eugerres brasilianus, Eucinostomus melanopterus and Diapterus rhombeus) in a tropical estuary in Northeast Brazil was assessed for 3 different size classes corresponding to juveniles, sub-adults and adults. In all, 425 individuals were analysed. The gut contents of 13.4% of these individuals

Testing the Optimal Foraging Theory in a Generalist Feeder: The Case of Reintroduced European Pond Turtles and Its Impact on Macroinvertebrates Communities

Ecology and Evolution, Volume 15, Issue 8, August 2025.
In this study we investigated the macroinvertebrate (MI) communities in two newly created, man‐made ponds concurrently with the diet of captive‐bred European pond turtles that were translocated there. We aimed at assessing whether turtles were operating as generalist feeders, and if successive reintroductions of turtles would affect the overall MI ...

Strategies, costs and counter‐strategies to sexual coercion

Biological Reviews, Volume 100, Issue 4, Page 1557-1577, August 2025.
ABSTRACT Sexual conflict, the conflict between the evolutionary interests of females and males over mating, occasionally results in the evolution of traits favourable for one sex and adverse for the other. In this context, males can use sexual coercion to increase their mating success, at the expense of their female targets' mate choice.

Length–Dry Mass Relationships of Aquatic Insects: Geographic and Taxonomic Variation in a Digital Database

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 ...

Spatiotemporal assessment of benthic macroinvertebrate communities in the Bermejo River Basin in the Ecuadorian Amazonia

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.
