Populations of trout living in streams\u00a0with a\u00a0small number of breeding\u00a0adults still have enough genetic variation to be able to adapt to environmental changes according to a new study. <\/span><\/p>\n

Researchers found that streams with as few as 70 adults had more genetic variation than expected. Such variation provides a greater ability to adapt to environmental changes. The study implies that it will be more difficult for scientists to predict how small animal populations will react to future environmental changes.<\/span><\/p>\n

The team studied a series of parallel streams in Cape Race, Newfoundland, some of which were no more than 100 m long. The trout populations studied are all genetically diverse but are believed to come from a common ancestor.<\/p>\n

Researchers are now working to develop tools that will be help biologists predict which populations will be most resilient in environment fragmented by humans or by natural causes.<\/span><\/p>\n
