Cormorant predation effects on fish populations: A global meta‐analysis
Fish and Fisheries, Volume 22, Issue 3, Page 605-622, May 2021., 2021 Abstract This paper provides the results from the first meta‐analysis to examine the impact of cormorant (Phalacrocoracidae) predation on fish. It is based on a systematic search of literature, covering studies using significance‐based hypotheses tests on the relation between fish parameters and cormorant abundance.

Northern range shift may be due to increased competition induced by protection of species rather than to climate change alone. [PDF]
Ecol Evol, 2018 The protection of the species may induce an increase in population that generates increasing competition for optimal feeding areas, which may induce a similar or even a higher northern range shift than the climate change does, or induce an opposite shift with differences between breeding and wintering populations.

Seabird guano fertilizes Baltic Sea littoral food webs. [PDF]
PLoS ONE, 2013 Nutrient enrichment in coastal marine systems can have profound impacts on trophic networks. In the Baltic Sea, the population of Great Cormorant (Phalacrocorax carbo sinensis) has increased nearly exponentially since the mid-1990 s, and colonies of ...

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 ...

Corneal power and underwater accommodation in great cormorants(Phalacrocorax carbo sinensis) [PDF]
Journal of Experimental Biology, 2003 SUMMARY In great cormorants (Phalacrocorax carbo sinensis), corneal refractive powers, determined by photokeratometry, ranged between 52.1 diopters (52.1 D) and 63.2 D. Photorefractive reflexes, determined by infrared video photorefraction, indicated that in voluntary dives the cormorants accommodate within 40-80 ms of submergence and ...

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.
