Interdisciplinary research initiated at Stony Brook University allowed us to cumulatively track historical dams built on Maine watersheds and estimate habitat lost to anadromous species over the past 400 years. A follow up paper documented the lost biomass and potential ecological consequences of habitat loss. Historical research has been expanded…

With Drs. Andy Danylchuk (UMass), Bryan M. DeAngelis (The Nature Conservancy),Gregory Skomal (MA DMF) and Richard Nemeth (University of the Virgin Islands), Jordaan has collaborated on “Building a multi-institutional effort to understand regional connectivity: linking fish, essential habitats and ecosystems for effective marine resource management”. With National Park Service and…

This project identifies Atlantic sturgeon aggregation areas and delineate movement patterns along the eastern US coastline. We employ mark-recapture techniques combined with growth, mortality, diet and genetic analyses. Large acoustic arrays link fish movements local and regional oceanographic patterns, allowing us to recommend a network of protected areas that are…

With Drs. Allison Roy and Andrew Whiteley (UMass), and in collaboration with the Massachusetts Division of Marine Fisheries (MA DMF), we are investigating the productivity of river herring in lakes from Connecticut to Maine to determine the possible causes of variability. By employing different techniques to estimate productivity we determine…

Mapping the spatial distributions of species and subpopulations across different scales show how ecosystem considerations and human influences can alter multi-species relationships and ecological communities. This information is necessary to designing successful protected area that benefit a variety of species across a range of life stages and also promote sustainable…
