The Genetics Behind the Killifish's Adaptation to Pollution
Research Brief - January 2017
Killifish living in four polluted East Coast estuaries have adapted quickly to survive high levels of toxic industrial pollutants. In a new study, researchers explored the complex genetics involved in the Atlantic killifish's resilience, bringing us one step closer to understanding how they rapidly evolved to tolerate normally lethal levels of environmental contaminants. Exploring the evolutionary basis for these genetic changes may provide new information about the mechanisms of environmental chemical toxicity in both animals and humans.
Some Fish Quickly Adapt to Lethal Levels of Pollution
SRP News Page - December 2016
Evolution is working under pressure to rescue some coastal fish from a lethal, human-altered environment. Now, a new study has revealed the complex genetic basis for the Atlantic killifish's remarkable resilience.
Genetic variation may explain PCB-resistance in Atlantic killifish
Environmental Factor - March 2014
Changes in a receptor protein may explain how killifish developed a genetic resistance to polychlorinated biphenyls (PCBs) in New Bedford Harbor, Mass., according to a new study published in the journal BMC Evolutionary Biology.
