Sitting beside a small stream in the southwestern Adirondacks, Spencer Bruce clipped a tiny brook-trout fin and placed it in a small container. The fin is one of more than a thousand he has collected in recent years from waters in New York State for a genetic study.
Studying the genetic makeup of fish may provide clues to how resilient a population is to climate change and other environmental problems. In the Adirondack Park, several cold-water species of fish are thought to be at risk from climate change. Besides brook trout, they include lake trout and round whitefish. Other aquatic species, including amphibians and loons, also could be at risk. » Continue Reading.
