Effect of laying sequence on egg mercury in captive zebra finches: an interpretation considering individual variation.

abstract：:The present study determined the effects of environmentally relevant, short-term (4-h) exposure to the pyrethroid insecticide esfenvalerate on mortality, food consumption, growth, swimming ability, and predation risk in larvae of the fathead minnow (Pimephales promelas). Acute effect concentrations were determined, an...
