New England’s climate is changing faster than that of any other region in the continental United States. Over the last century, Maine has experienced an increase in annual temperature of approximately 1.48oC along with a 15 percent increase in annual precipitation.

Therefore, changes in regional climate could undermine the structure and stability of Maine’s freshwater systems as they currently exist.
Maine currently harbors the last wild populations of Atlantic salmon (Salmo salar) in the United States. Atlantic salmon were once abundant in Maine …

Seals are often perceived as predators and competitors for fish, and as a result, come into conflict with fisheries and fish conservation. Increasing numbers of seals have become a recent concern in the Penobscot River Estuary in Maine, as habitat restoration and diadromous fish conservation have been top priorities in this region for the past decade.
To understand how pinnipeds are responding to these efforts, as well as the risks they pose to …
