摘要: Abstract Mercury, a common wetland pollutant, can affect wildlife populations through acute toxicity or physiological effects that modify behavior and negatively influence reproductive success. We compared body-feather mercury concentrations of free-living male female adult White Ibises (Eudocimus albus) during three breeding seasons in the Florida Everglades examined relationships among mercury, hormone concentrations, body-condition scores. Female consistently had lower than males. Prebreeding females' estradiol were correlated with concentrations. However, we found no relationship between testosterone, progesterone, corticosterone Incubating showed significant positive testosterone but other hormonal correlations used seven-year standardized data set Gr...
