Toxicity of seleno-l-methionine, seleno-dl-methionine, high selenium wheat, and selenized yeast to mallard ducklings Toxicity of seleno-l-methionine, seleno-dl-methionine, high selenium wheat, and selenized yeast to mallard ducklings
The toxicity of four chemical forms of selenium (seleno-L-methionine, seleno-DL-methionine, selenized yeast, and high selenium wheat) was compared in day-old mallard ducklings (Anas platyrhynchos). In the first experiment, in which the basal diet was 75% wheat, survival after 2 weeks was lower for ducklings fed 30 μg/g selenium as seleno-L-methionine (36%) than for ducklings fed 30 μg/g...

Reproductive success, growth and survival of black-crowned night-heron (Nycticorax nycticorax) and snowy egret (Egretta thula) chicks in coastal Virginia Reproductive success, growth and survival of black-crowned night-heron (Nycticorax nycticorax) and snowy egret (Egretta thula) chicks in coastal Virginia
We studied reproductive success, growth, and survival of Black-crowned Night-Heron (Nycticorax nycticorax) and Snowy Egret (Egretta thula) chicks in two mixed-species heronries on marsh islands in Chincoteague Bay, Accomack County, Virginia in 1992 and 1993. We attached radio transmitters with mortality sensors to the oldest chicks (A-chicks) in 11 to 22 nests of both species to monitor...

Comparison of the effects of seleno-Lmethionine, seleno-DL-methionine, and selenized yeast on reproduction of mallards Comparison of the effects of seleno-Lmethionine, seleno-DL-methionine, and selenized yeast on reproduction of mallards
The toxicities of seleno-l-methionine, seleno-dl-methionine, and selenized yeast were compared. Ten pairs of mallards were fed a control diet and 15 pairs were fed diets containing 10 ppm selenium as seleno-dl-methionine, seleno-l-methionine, or selenized yeast. Hatching of fertile eggs was significantly lower for females fed 10 ppm selenium as seleno-dl-methionine (7.6%) and seleno-l...

Silver Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review Silver Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review
Ecological and toxicological aspects of silver (Ag) in the environment are briefly summarized with an emphasis on natural resources. Elevated silver concentrations in biota occur in the vicinities of sewage outfalls, electroplating plants, mine waste sites, and silver-iodide seeded areas; in the United States, the photography industry is the major source of anthropogenic silver...

Planar PCB Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review Planar PCB Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review
Ecological and toxicological aspects of polychlorinated biphenyls (PCBs) in the environment are reviewed with emphasis on biologically active congeners and fish and wildlife. Subtopics include sources and uses, chemical and biochemical properties, concentrations in field collections, lethal and sublethal effects, and recommendations for the protection of sensitive resources. All...

On NAAMP and the use of the Internet as a forum for evolving science On NAAMP and the use of the Internet as a forum for evolving science
Traditionally, science has been communicated through peerreviewed hardcopy. With the rapid growth of internet technology, many new potentials for sharing and evolution of ideas are possible: open, low cost communication between researchers, both accredited and amateur, may allow not joint problem solving at scales previously not possible. Conservation especially, is a dynamic field which...
