Effects of ethynylestradiol on the reproductive physiology in zebrafish (Danio rerio): time dependency and reversibility.

abstract：:Northern bobwhite (quail) (Colinus virginianus) and scaled quail (Callipepla squamata) populations have declined dramatically in the Rolling Plains ecoregion of Texas and Oklahoma (USA). There is rising concern about potential toxicity of neonicotinoids to birds. To investigate this concern, the authors examined crops...
