Main and interactive effects of arsenic and selenium on mallard reproduction and duckling growth and survival Main and interactive effects of arsenic and selenium on mallard reproduction and duckling growth and survival

Ninety-nine pairs of breeding mallards (Anas platyrhynchos) were fed diets supplemented with As (sodium arsenate) at 0, 25, 100, or 400 μg/g, in combination with Se (seleno-DL-methionine) at 0 or 10 μg/g, in a replicated...

Regular and homeward travel speeds of arctic wolves Regular and homeward travel speeds of arctic wolves
Single wolves (Canis lupus arctos), a pair, and a pack of five habituated to the investigator on an all-terrain vehicle were followed on Ellesmere Island, Northwest Territories, Canada, during summer. Their mean travel speed was measured on barren ground at 8.7 km/h during regular travel and 10.0 km/h when returning to a den.
