Using species distribution models to define nesting habitat of the eastern metapopulation of double‐crested cormorants

Ecology and Evolution, 2017
When organisms with similar phenotypes have conflicting management and conservation initiatives, approaches are needed to differentiate among subpopulations or discrete groups.

Citizen science reveals host‐switching in louse flies and keds (Diptera: Hippoboscidae) during a period of anthropogenic change [PDF]

Medical and Veterinary Entomology, Volume 40, Issue 2, Page 305-322, June 2026.
A study of louse flies in the United Kingdom, Isle of Man, and Ireland found 212 different interactions between Hippoboscidae and their hosts, of which 70 were previously unrecorded. No louse flies were found on aquatic species of birds. Host‐switching to gulls (Laridae) has occurred during a period in which these species have started relying on ...

Fish consumption by great cormorants in Norwegian coastal waters—a human-wildlife conflict for wrasses, but not gadids

ICES Journal of Marine Science, 2021
Piscivorous wildlife is often perceived as competitors by humans. Great cormorants of the continental subspecies (Phalacrocorax carbo sinensis) in the Baltic and North Sea increase, while local cod (Gadus morhua) stocks decline. In contrast, numbers of

Microplastics in the diet of nestling double-crested cormorants (Phalacrocorax auritus), an obligate piscivore in a freshwater ecosystem

Canadian Journal of Fisheries and Aquatic Sciences, 2019
Anthropogenic debris, namely plastic, is a concern across aquatic ecosystems worldwide, with freshwater systems being understudied relative to marine systems.

Dynamic Responses in a Plant-Insect System to Fertilization by Cormorant Feces

Insects, 2015
Theoretical arguments suggest that increased plant productivity may not only increase consumer densities but also their fluctuations. While increased consumer densities are commonly observed in fertilization experiments, experiments are seldom performed ...

Management of Double-Crested Cormorants to Improve Sport Fisheries in Michigan: Three Case Studies

Human-Wildlife Interactions, 2017
Impacts of double-crested cormorants (Phalacrocorax auritus) to fisheries have been documented, but evaluation of the process and outcomes of cormorant management to reduce impacts on fisheries is lacking. We provide a synthesis of adaptive management of

Developing nondestructive techniques for managing conflicts between fisheries and double‐crested cormorant colonies

Wildlife Society Bulletin, 2015
Double‐crested cormorants (Phalacrocorax auritus) have been identified as the source of significant mortality to juvenile salmonids (Oncorhynchus spp.) in the Columbia River Basin.
