Stream contamination and biodiversity

Zach Culumber is studying the genetic consequences of stream contamination to biodiversity in Mexico. He is using swordtail fish as a model, and is investigating the interaction between the swordtail mating system and the genetics of hybridization that have resulted from break down of the swordtail’s ability to recognize other individuals of their own species. Stream pollution has resulted in two species of swordtails hybridizing. He is working closely with local residents and indigenous organizations and Mexican university researchers in Calnali, Mexico to carry out the research and the consider implications for long-term health of social and ecological communities in the region. He also is publishing and presenting at scientific meetings and he attended the IGERT national meeting in 2008.
