Site fidelity of wintering cormorants Phalacrocorax carbo sinensis in Europe [PDF]

Wildlife Biology, 2002
The breeding population of cormorants Phalacrocorax carbo sinensis has expanded more than twenty‐fold in continental Europe since 1970, and these large piscivorous birds cause conflicts with human fishery interests in large parts of Europe, including areas outside their breeding range ...

Cypriniform fish in running waters reduce hyporheic oxygen depletion in a eutrophic river

Freshwater Biology, Volume 65, Issue 9, Page 1518-1528, September 2020., 2020
Abstract The hyporheic zone is an important habitat for benthic invertebrates and early‐developmental stages of gravel spawning fish. However, the eutrophication of running waters and, in turn, the excessive periphyton biomass leads to its biological clogging.

Competition for food between the Mediterranean shag, the great cormorant and artisanal fisheries: a case study

Scientia Marina, 2018
The Mediterranean shag (Phalacrocorax aristotelis desmarestii) and the great cormorant (P. carbo sinensis) are syntopic birds in an area encompassing Grosa Island and the Mar Menor coastal lagoon (SE Spain, western Mediterranean) during the breeding ...

Vocal behaviour of the Great Cormorant Phalacrocorax carbo sinensis during the breeding season [PDF]

Bird Study, 2021
Capsule: Great Cormorants Phalacrocorax carbo sinensis use vocal communication during the breeding season, with males being particularly vocal earlier in the breeding cycle and showing individual variation in some calls, which could be used for individual recognition.

APPLICATION OF THE GREAT CORMORANT'S (Phalacrocorax carbo sinensis) DAILY MEAL IN THE STIMATION OF DAMAGES AT FISHPONDS [PDF]

Croatian Journal of Fisheries, 2004
Daily meal of the Great Cormorant (Phalacrocorax carbo sinensis), joined with the number of birds and composition of fish in the meal, has high importance in total calculation of damage-costs on fish stock.

Roosting Colony of Cormorants (Phalacrocorax Carbo Sinensis L.) as a Source of Nutrients for the Lake

Limnological Review, 2015
Since 2005, great cormorants have been observed on the Lake Góreckie (Wielkopolski National Park) shoreline. The population of these birds occurring within the lake has gradually increased. In autumn 2008, more than 100 individuals were observed.

Changes in physico-chemical conditions and macrophyte abundance in a shallow soft-water lake mediated by a Great Cormorant roosting colony

Journal of Limnology, 2014
This study examined the effects of the Great Cormorant (Phalacrocorax carbo sinensis L.) roosting colony on the physico-chemical conditions and macrophyte abundance in a shallow soft-water lobelia lake. We compared data collected in 1998 and 2009, before

Relationships between bird morphology and prey selection in two sympatric Great Cormorant Phalacrocorax carbo subspecies during winter.

, 2009
International audienceVariation in bird morphology (notably sex size dimorphism) has been suggested to contribute to differences in food use between individuals. We explore the hypothesis of food partitioning (diet overlap and prey size selection) in two

Metabolic rate throughout the annual cycle reveals the demands of an Arctic existence in Great Cormorants [PDF]

, 2011
Aquatic endotherms living in polar regions are faced with a multitude of challenges, including low air and water temperatures and low illumination, especially in winter. Like other endotherms from cold environments, Great Cormorants (Phalacrocorax carbo)
