EPO Activity: EPO: Citizen Science Study of Distributed Domestic Water Heater Microbiology Diversity
Presently, there is a growing interest in the biogeography of microorganisms. By looking at the genetic differences from isolates of similar microbes from across the globe, researchers are currently trying to understand the degree to which populations of microbes are isolated and whether this isolation suggests an allopatric speciation model for prokaryotes. We propose to conduct a citizen science pilot study of microbial diversity in water heaters to both, (1) access the feasibility of basing a citizen science project on field microbiology, and (2) generate a first image of the biogeographic distribution of thermophilic microorganisms across the United States.
We had 212 requests for sampling packets, so we were able to distribute them around the United States and collected at least one sample from every state. By March 2012 we had 101 samples returned, at least one from every state in addition to the District of Columbia and Puerto Rico. The PSARC team is now analyzing the samples to determine the biogeographic distribution of themophilic organisms across the United States.
