Restoration of contaminated ecosystems: adaptive management in a changing climate

Autor: Kevin McAbee, John P. Isanhart, Diane L. Larson, Christopher J. Walsh, Aïda M. Farag, Ralph G. Stahl, Jenny L. Stauber

Publikováno v: Restoration Ecology. 25:884-893

Three case studies illustrate how adaptive management (AM) has been used in ecological restorations that involve contaminants. Contaminants addressed include mercury, selenium, and contaminants and physical disturbances delivered to streams by urban

Polybrominated diphenyl ethers in bald (Haliaeetus leucocephalus ) and golden (Aquila chrysaetos ) eagles from Washington and Idaho, USA

Autor: Brian L. Spears, John P. Isanhart

Publikováno v: Environmental Toxicology and Chemistry. 33:2795-2801

Little is known about the exposure and accumulation of polybrominated diphenyl ethers (PBDEs) in the 2 species of eagles inhabiting North America. The authors analyzed the livers of 33 bald eagles and 7 golden eagles collected throughout Washington a

Marsh Wrens As Bioindicators of Mercury in Wetlands of Great Salt Lake: Do Blood and Feathers Reflect Site-Specific Exposure Risk to Bird Reproduction?

Autor: Joshua T. Ackerman, C. Alex Hartman, Mark P. Herzog, Garth Herring, John P. Isanhart

Publikováno v: Environmental Science & Technology. 47:6597-6605

Nonlethal sampling of bird blood and feathers are among the more common ways of estimating the risk of mercury exposure to songbird reproduction. The implicit assumption is that mercury concentrations in blood or feathers of individuals captured in a

Reprint of: CYP1A protein expression and catalytic activity in double-crested cormorants experimentally exposed to Deepwater Horizon Mississippi Canyon 252 oil

Autor: John P. Isanhart, Courtney R. Alexander, Kim D. Smelker, Caleshia S. Calvin, Dave Cacela, Michael J. Hooper, Karen M. Dean, Susan A. Shriner, Jane E. Link, Céline A.J. Godard-Codding, Steve Bursian, Katie C. Hanson-Dorr, Katherine E. Horak, Fred L. Cunningham

Publikováno v: Ecotoxicology and environmental safety. 146

Double-crested cormorants (Phalacrocorax auritus, DCCO) were orally exposed to Deepwater Horizon Mississippi Canyon 252 (DWH) oil to investigate oil-induced toxicological impacts. Livers were collected for multiple analyses including cytochrome P4501

Reprint of: Overview of avian toxicity studies for the Deepwater Horizon Natural Resource Damage Assessment

Publikováno v: Ecotoxicology and environmental safety. 146

The Oil Pollution Act of 1990 establishes liability for injuries to natural resources because of the release or threat of release of oil. Assessment of injury to natural resources resulting from an oil spill and development and implementation of a pl

Fipronil toxicity in northern bobwhite quail Colinus virginianus: Reduced feeding behaviour and sulfone metabolite formation

Autor: Malsha Kitulagodage, William A. Buttemer, John P. Isanhart, Lee B. Astheimer, Michael J. Hooper

Publikováno v: Chemosphere. 83:524-530

Fipronil is a phenyl pyrazole insecticide registered for agricultural use in many countries. Avian exposure to fipronil occurs mainly by ingesting contaminated insects or seeds. There is little information regarding the toxicological effects of fipro

Responses of glutamate cysteine ligase and glutathione to oxidants in deer mice (Peromyscus maniculatus)

Autor: John P. Isanhart, Michael J. Hooper, Tobias J. McBride, Hongmei Wu, Stephen B. Cox

Publikováno v: Ecotoxicology and Environmental Safety. 72:1572-1578

Sensitivities of a wildlife species, deer mice, to oxidants were evaluated. A single dose (1589 mg/kg body weight by intraperitoneal injection) of carbon tetrachloride, a typical hepatotoxicant, caused changes in GCL activity and GSH content in multi
