Estimating competition between wildlife and humans-a case of cormorants and coastal fisheries in the Baltic Sea. [PDF]

PLoS ONE, 2013
Cormorants and other wildlife populations have come in real or perceived conflicts with humans over exploited fish stocks. From gut contents of cormorants, and using an extension of the Catch equation, we estimated the degree of short term competition ...

Cormorant catch concerns for fishers: estimating the size-selectivity of a piscivorous bird. [PDF]

PLoS ONE, 2013
Conflict arises in fisheries worldwide when piscivorous birds target fish species of commercial value. This paper presents a method for estimating size selectivity functions for piscivores and uses it to compare predation selectivities of Great ...

Nonrandom spatial distribution of Neotropic Cormorants (Phalacrocorax brasilianus) along a coastal highway in Lima, Peru.

PLoS ONE, 2021
Neotropic Cormorants (Phalacrocorax brasilianus) are common seabirds along the Peruvian coast. They frequently perch on trees, poles and port structures in urban areas, producing guano that builds up in areas of high levels of human activity. Hundreds of

Investigation of Commensal Escherichia coli Populations of Cormorant Hatchlings in the Absence of Anthropogenic Impacts in Remote Areas of West Mongolia

Microorganisms, 2021
To increase our understanding of bacterial intestinal colonization in animal populations lacking substantial anthropogenic influence we studied the diversity of E. coli in cormorants from the pristine West-Mongolian steppe. E.

Coexistence of three sympatric cormorants (Phalacrocorax spp.); partitioning of time as an ecological resource [PDF]

Royal Society Open Science, 2016
Resource partitioning is well known along food and habitat for reducing competition among sympatric species, yet a study on temporal partitioning as a viable basis for reducing resource competition is not empirically investigated.

Emergence, spread, and impact of high-pathogenicity avian influenza H5 in wild birds and mammals of South America and Antarctica. [PDF]

Conserv Biol
Abstract The currently circulating high‐pathogenicity avian influenza (HPAI) virus of the subtype H5 causes variable illness and death in wild and domestic birds and mammals, as well as in humans. This virus evolved from the Goose/Guangdong lineage of the HPAI H5 virus, which emerged in commercial poultry in China in 1996, spilled over into wild birds,

The great Cormorant (Phalacrocorax carbo) at lower lake Constance/Germany: dietary composition and impact on commercial fisheries

Knowledge and Management of Aquatic Ecosystems, 2014
At lower lake Constance, the number of cormorants (Phalacrocorax carbo) has greatly increased during the last 15 years. An investigation of their diet can help to estimate the impact on fish and fisheries.
