Individuals occupying dominant and subordinate positions in social hierarchies exhibit
divergent behaviours, physiology and neural functioning. Dominant animals express higher …

The effect of a pollutant on the base of the food web can have knock-on effects for trophic
structure and ecosystem functioning. In this study we assess the effect of microplastic …

Currently, there are few mechanistic fitness-based habitat selection models for stream fishes
and most models used by management agencies focus on physical habitat alone. In this …

Coastal habitats, such as seagrasses, mangroves, rocky and coral reefs, salt marshes, and
kelp forests, sustain many key fish and invertebrate populations around the globe. Our …

Baited remote underwater video systems are becoming a widely adopted tool for sampling
fish assemblages. One of the outstanding knowledge gaps associated with this technique is …

Trophic interactions are important factors structuring animal communities. We assessed the
trophic relations of four fish species that live in sympatry in the River Ladra (NW Spain), and …

This study describes the seasonal feeding habits of different size classes of Cathorops spixii
and Cathorops agassizii along an estuarine ecocline and the food overlap when different …

The feeding strategy, overlap and trophic interactions of four demersal catfishes inhabiting
Cochin Estuary, Arius maculatus (n= 67), A. subrostratus (n= 63), A. arius (n= 21) and …

The present work aims to characterize a fish assemblage from a northeastern Brazilian
estuary according to its diet and trophic organization along the estuarine-reef gradient …

The brown trout (Salmo trutta) is a species of Eurasian origin, but at has become naturalized
in many other parts of the world. It has an outstanding socio-economic importance, both in …
