Abstract
American toad (Bufo americanus) tadpoles were exposed to cadmium from shortly after hatching through metamorphosis. Cadmium at 540 microg/L decreased percentage survival and metamorphosis; 5 and 54 microg/L increased growth relative to controls. Amphibians exposed to cadmium as tadpoles may be less tolerant of natural stressors in the terrestrial environment.
摘要
美洲蟾蜍（Bufo americanus）蝌蚪从孵化后不久到变态期一直暴露于镉中。540微克/升的镉降低了存活率和变态率；5微克/升和54微克/升的镉相对于对照组增加了生长。蝌蚪期暴露于镉的两栖动物可能对陆地环境中的自然应激源耐受性较低。
