"Species of plants and animals will shift as the climate changes. We're already seeing more exotic species from Iowa and places to the south of Minnesota move into Minnesota waters. As the period of ice-free conditions on our lakes and rivers increases you're going to have a longer growing season, but also a longer growing season for things that are not very desirable like zebra mussels and other invasive species.

"We're already seeing evidence that those types of species are overwintering more successfully in Minnesota. What we don't yet know is how those invasive alien species will interact with our nice native Minnesota species and what those interactions will produce in the new environment."
