Alan Boyle writes:A years-long study at the University of Florida suggests
that mercury pollution can alter the hormones of white ibises to make males
more likely to mate with other males.
"We knew that mercury can disrupt hormones -- what is most disturbing about
this study is the low levels of mercury at which we saw effects on hormones
and mating behavior," Peter Frederick, a wildlife ecology and conservation
professor who led the study, said in a news release this week. "This
suggests that wildlife may be commonly affected."
The study was published online on Wednesday in the
Proceedings of the Royal Society B.
