dieldrin-induced mortality in an endangered species, the gray bat (myotis grisescens).	brains of juvenile gray bats, myotis grisescens, found dead beneath maternity roosts in two missouri caves contained lethal concentrations of dieldrin. one colony appeared to be abnormally small, and more dead bats were found a year after the juvenile bats had been collected. this is the first report to link the field mortality of bats directly to insecticide residues acquired through the food chain.	1978	564550
