Very Interesting

"Other studies on movement ecology indicate that salmon may be particularly resilient to regional environmental change. Westley is part of a research team that revealed that salmon stray from smaller groups at higher rates than they stray from larger groups. This happens because smaller groups of salmon have less information to share with each other and work from, so their ability to choose the correct path home is reduced.

If an environmental disturbance causes a new habitat to open up, it will quickly be colonized by straying salmon.

“As the population builds, the salmon will stop straying as much and start homing more,” Westley explained. “Then you will start to see local adaptation favoring traits that allow these particular salmon to do well in their new environment. This is how vibrant new populations are built.”
