Coastal Conversations Radio Program: Marine and Freshwater Ecosystems: Ecological Connections and Research Methods
Today’s coastal conversations is in honor of the annual spring running, that time of year when several species of fish, such as alewives and blue-back herring, return from the ocean to Maine’s streams and ponds to spawn. Our show is about marine and freshwater ecosystems, and specifically the ecological connections that occur where salt and freshwater meet, where fish, marine mammals, birds and even water itself, moves along freshwater and into the ocean.
We’ll learn about several research projects underway in these systems, and new research methods, like environmental DNA, as well as existing research methods, such as hook and line fishing, to understand the species that inhabit these zones. We’ll also talk about local and traditional ecological knowledge that gets handed down through generations and helps provide critical information on how to protect estuaries and fish.
Our guests will help us understand why we should care about the research programs that occur at the intersection of marine and freshwater estuaries. Our geographic scope will span the Downeast region, from the Penobscot River system all the way down to Passamaquoddy Bay on the Canadian border.
