Who are we?
The Tropical Research for Avian Conservation & Ecotoxicology (TRACE) Initiative is an international collaborative research network that generates scientific knowledge to inform tropical bird conservation through ecotoxicological monitoring.
Our Motivation
Mining, agriculture, and oil-producing industries have rapidly expanded throughout the tropical realm as alluring economic opportunities for developing nations to meet the demands of global markets. However, these industries can compromise sustainable development, human welfare, and biodiversity conservation via the contamination of impoverished communities and natural resources. Using birds as convenient, ecologically-important, and charismatic bioindicators, we seek to understand how increasing pollution emissions impact biological communities and may contribute to global biodiversity losses.
Our Vision
Ecotoxicological monitoring efforts over the past century have pursued discordant sampling strategies and focal species, while neglecting the most biologically-meaningful regions on the planet: the tropics. These decisions have limited our ability to make meaningful comparisons across time and space. By creating an inclusive and equitable data-sharing platform, the TRACE Initiative seeks to not only standardize sampling methods among monitoring programs, but also compile the world’s largest database of ecotoxin samples for tropical bird species. In doing so, we can hope to better understand the prevalence, persistence, and distribution of environmental pollution in tropical biomes, and how ecotoxins impact both resident and migratory bird populations.
Dismantling Systemic Barriers
TRACE provides an opportunity to dismantle systemic barriers and colonialist precedents in science. Through the equitable exchange of expertise, funding, resources, data, and authorship among collaborators, TRACE stands to (1) generate crucial research capacity in tropical nations, which are disproportionately impacted by environmental crises, (2) provide leadership opportunities for current and aspiring tropical scientists, and (3) produce standardized information on the prevalence, distribution, toxicokinetics, and biogeochemistry of environmental pollutants. Ultimately, we aim to disseminate this standardized information to local, national, and international government entities, including Parties of the United Nations Minamata Convention on Mercury, with the intent to create positive impacts for local communities.
Our History
TRACE grew from over a decade of bird sampling research by the Biodiversity Research Institute (BRI) throughout Central America and the West Indies. In 2007, BRI field biologists and a variety of collaborating bird banders began collecting blood and feather samples from resident and migratory bird species to assess mercury exposure across the Neotropics. As an Executing Agency for the United Nations Minamata Convention on Mercury, BRI has worked with national governments and local stakeholders to initiate mercury monitoring programs throughout the Caribbean, Amazon and Congo Basins, and Indo-Pacific regions. TRACE builds upon key partnerships with organizations such as Centro de Innovación Científica Amazónica (CINCIA), the Cornell Lab of Ornithology, and el Monitoreo de Sobrevivencia Invernal (MoSI) banding program with the Institute for Bird Populations (IBP). TRACE now incorporates over 2,500 mercury samples from 309 bird species collected across 14 countries.
How to Get Invovled
TRACE supports and welcomes direct collaboration with researchers, especially students based in tropical institutions, that collect whole blood, feathers, or eggs from tropical birds. If you would like to contribute samples to our cause, please fill out this form, and we will send you additional information.
