Effect of piscivorous and omnivorous colonial birds’ activity on structure, abundance and diversity of soil free-living nematodes. Preliminary results from a study of the impact of avifauna on soil biota in Israel’s Mediterranean Coastal Plain

, 2019
The soil biota, including soil microorganisms and free-living nematodes, was investigated in the nesting and roosting habitats of the following piscivorous and omnivorous colonial birds: black kite (Milvus migrans), great cormorant (Phalacrocorax carbo),

Commensal association of piscivorous birds with foraging Eurasian otters in Spain

2020
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

Recovery of infectious pancreatic necrosis virus from the faeces of wild piscivorous birds

Aquaculture, 1992
Abstract Faecal samples were collected from wild birds frequenting salmonid fish hatcheries to determine if birds excrete infectious pancreatic necrosis (IPN) virus in their faeces. Samples were collected from early June through early September. IPN virus was detected in faeces from herons, mallards, and other birds at titres similar to the titres ...
