Effects of dietary selenium on reproduction and body mass of captive lesser scaup.

abstract：:Temperature is an important factor affecting toxicity, determining chemical toxicokinetics and toxicodynamics in poikilothermic organisms. Because metabolic rates are also affected by temperature, interactions between the emergence of toxic effects and time are very likely. The aim of the present study was to investig...
