Temperature effects on osmoregulation were studied in larval
Ambystoma gracile. There was a pronounced effect on the osmotic
uptake of water through the skin. The rates at 5°C, 15°C and 25°C
were respectively 0.03 ml/hr., 0.1 ml/hr. and 0.2 ml/hr. for a
10g animal. The Q₁₀'s for these changes in...
Three experimental grazing trials were conducted to
explore the hypothesis that in the Klamath Basin, a higher
level of selenium supplementation is necessary than those
proven adequate elsewhere. Two forage species were
investigated: Festuca arundinaeca and Agropyron repens, in
0.61 hectare plots, both grown in a selenium deficient soil
area....
