BRI in the News

BRI news stories have appeared in many regional, national, and international news outlets. These stories help promote awareness of our work, but also promote the general issues of conservation biology and the need to continue research in wildlife health and its implications to human health.

BRI's researchers are available to talk to journalists and provide expert information on both their work and the broader topics of their expertise.

BRI Publishes New Study on Maternal Mercury Transfer in Birds


BRI research on mercury transfer in birds was recently published in the journal, Environmental Science and Technology. The article, Synthesis of Maternal Transfer of Mercury in Birds: Implication for Altered Toxicity Risk, reviews published and unpublished data on maternal transfer of methylmercury in birds. Researchers used paired samples of females' blood and their eggs from 26 bird species in six taxonomic orders. The study shows that total mercury (THg) concentrations in eggs increases with maternal blood THg; however, the proportion of THg transferred from females to their eggs differed among bird taxa and with maternal THg exposure. This study provides equations that can be used to predict THg concentrations in eggs using female blood THg concentrations, and vice versa, which may help translate toxicity benchmarks across tissues and life stages in future studies.
