Mercury (Hg) Exposure in Marine Communities

Rebecka Brasso (UNCW)

There is growing evidence that trophic transfer and long-range transport can lead to the export of anthropomorphic mercury (Hg) to remote ecosystems. I am collaborating with Rebecka Brasso (UNCW) on integrating measures of tissue stable isotopes and Hg concentration to assess the relative influence of trophic and geographic sources of Hg in marine birds. This work suggests that life history behaviors can mediate contaminant exposure among community members experiencing a common environmental Hg background. I am excited to expand this focus in the future and examine the trophic transfer of Hg in aquatic and marine ecosystems.
