Commensal association of piscivorous birds with foraging Eurasian otters in Spain

, 2019
Positive interactions among species are widespread in nature. In a foraging context, these interactions may consist of local enhancement, when an individual uses cues from individuals of another species to locate food, or facilitation when food is made more readily available by the individuals of other species. Facilitation may evolve as mutualism when

Urban waterbirds shifting microplastics

Environmental Challenges
Plastic pollution in aquatic ecosystems poses growing ecological risks, particularly for piscivorous birds occupying higher trophic levels. This study assessed the ingestion and excretion patterns of microplastics (MPs) in two monotypic urban inland ...
