Plastic ingestion in aquatic birds in Portugal

Marine Pollution Bulletin, 2019
In modern society, plastic items have become indispensable. The rapid growth of plastic production has led to an increase in the concentration of plastic waste in the environment and, consequently, wildlife has been severely affected. As wide-ranging foragers and predators, aquatic birds are ideal sentinels for monitoring changes in their environment ...

Role of selenium toxicity and oxidative stress in aquatic birds

Aquatic Toxicology, 2002
Adverse effects of selenium (Se) in wild aquatic birds have been documented as a consequence of pollution of the aquatic environment by subsurface agricultural drainwater and other sources. These effects include mortality, impaired reproduction with teratogenesis, reduced growth, histopathological lesions and alterations in hepatic glutathione ...

Strychnine Poisoning of Aquatic Birds

Journal of Wildlife Diseases, 1987
Strychnine poisoning was diagnosed in free-flying mallards (Anas platyrhynchos) and a ring-billed gull (Larus delawarensis) found dead on a pond in a zoo. The probable source of toxin was improperly applied strychnine-treated grain used for control of rodents on adjacent farm land. Ingesta of the birds contained 19.7-85.1 mg/kg of strychnine.

Functional morphology of the forelimb musculature reflects flight and foraging styles in aquatic birds

Journal of Ornithology, 2021
Aquatic birds show a great diversity of locomotion styles and wing morphologies, from penguins that are fully specialized for an aquatic life to species of aerial flyers that also use their wings for underwater propulsion (e.g.

Selenium toxicosis in wild aquatic birds

Journal of Toxicology and Environmental Health, 1988
Severe gross and microscopic lesions and other changes were found in adult aquatic birds and in embryos from Kesterson Reservoir (a portion of Kesterson National Wildlife Refuge), Merced County, Calif., during 1984. Adult birds from that area were emaciated, had subacute to extensive chronic hepatic lesions, and had excess fluid and fibrin in the ...

Impact of cadmium on aquatic bird Cairina moschata

BioMetals, 2009
The impact on palmiped Cairina moschata of two levels of dietary cadmium (Cd) contamination (C1: 1 mg kg(-1) and C10: 10 mg kg(-1)) was investigated on liver gene expression by real-time PCR. Genes involved in mitochondrial metabolism, in antioxidant defences, detoxification and in DNA damage repair were studied. Metallothionein (MT) protein levels and

REHABILITATING OILED AQUATIC BIRDS

International Oil Spill Conference Proceedings, 1975
ABSTRACT In the 1971 San Francisco oil spill, $900.00 was spent per successfully released bird, with 95% of the 4,686 treated birds dying in captivity. Through continuing research and development, those figures are improving. In 1973, the International Bird Rescue Research Center (IBRRC) treated 523 oiled birds with a 41% survival rate ...
