Feces from Piscivorous and Herbivorous Birds Stimulate Differentially Phytoplankton Growth [PDF]

Water, 2019
Aquatic birds may impact shallow ecosystems via organic and nutrient enrichment with feces. Such input may alleviate nutrient limitation, unbalance their ecological stoichiometry, and stimulate primary production. Herbivorous and piscivorous birds may produce different effects on aquatic ecosystems due to different physiology, diet and feces elemental ...

Digenean trematodes (Trematoda: Digenea) parasitizing the digestive system of the great cormorant (Phalacrocorax carbo) in Hungary. [PDF]

Helminthologia
Great cormorants (Phalacrocorax carbo) are widespread piscivorous birds, which cause huge economic losses in the fish fauna worldwide. As a consequence of their predatory behaviour, they serve as definitive hosts for many digenean trematodes, and their ...

An Integrative Approach to Assessing the Impact of Mercury (Hg) on Avian Behaviour: From Molecule to Movement. [PDF]

J Xenobiot
Mercury (Hg) pollution is a widespread ecological threat with sublethal effects on wildlife. Birds, due to their ecological diversity and sensitivity, serve as effective models for evaluating the behavioural impacts of Hg exposure.

Spatio-temporal distributions of piscivorous birds in a subarctic sound during the nonbreeding season

Deep Sea Research Part II: Topical Studies in Oceanography, 2018
Abstract Understanding bird distributions outside of the breeding season may help to identify important criteria for winter refuge. We surveyed marine birds in Prince William Sound, Alaska, USA over nine winters from 2007 to 2016. Our objectives were twofold: to examine the seasonal patterns of piscivorous species overwintering in Prince William ...

EXPERIMENTAL BOLBOPHORUS DAMNIFICUS (DIGENEA: BOLBOPHORIDAE) INFECTIONS IN PISCIVOROUS BIRDS [PDF]

Journal of Wildlife Diseases, 2009
In order to determine potential definitive hosts of the digenetic trematode, Bolbophorus damnificus, two American White Pelicans (Pelecanus erythrorhynchos), two Double-crested Cormorants (Phalacrocorax auritus), two Great Blue Herons (Ardea herodias), and two Great Egrets (Ardea alba) were captured, treated with praziquantel, and fed channel catfish ...
