James A. Nelson
I am an interdisciplinary scientist most interested in the fish related components of marine ecosystems. I use a combination of field surveys, experimental approaches, stable isotope analysis, and mathematical modeling to quantify the functional role of marine organisms in mediating energy flow, biogeochemical cycles, and community structure.
Current Lab Members
Lab Manager - Full C.V.
I received my B.S. in Environmental Biology from the State University of New York College of Environmental Science and Forestry (SUNY ESF) in 2014 and my M.S. in Marine Biosciences from the University of Delaware in 2019. My scientific background mainly consists of photobiology and ecophysiology. My Master's work used an anemone (Exaiptasia pallida) as a model organism for corals. I worked to examine the relationship between anemones/coral and their algal symbionts under thermal stress. Joining the Nelson Lab I have switched gears a bit to supervise the Ship Shoal project and a project in the Florida Coastal Everglades examining food-web dynamics.
Research Technician - Full C.V.
I received my B.S. in Environmental Biology from the University of Delaware in 2018. Since then I have worked for Americorp as an Invasive Plant Technician, a Naturalist for the Department of Natural Resources and Environmental Regulation at the Aquatic Resources Education Center, and a tutor for students 1st-12th grade. I am joining the Nelson Lab as a research technician and I am excited to explore some new facets of research including working in the Broussard Assimilation Wetland and helping out on the Ship Shoal project to help me further explore which niches really pique my interests as a scientist.
Justin S. Lesser
PhD Student - Full C.V.
My research focuses on trophic niches and energy flow in food webs. My work is relevant for all types of habitats but has recently focused on seagrass and saltmarsh ecosystems. As a grad student at the Plum Island Ecosystems LTER site, I study how landscape features influence the movement of energy from the marsh surface to the creek by an abundant fish consumer, the mummichog. I also study how environmental and physical drivers of ecosystem productivity influence energy flow and food web efficiency through time and across the estuary. I am very interested in cross-habitat, consumer-mediated flows of energy, either by prey migrations to other habitats or by predators coupling habitats in space, participating in multiple food webs by moving between them. I received my B.S. in Neuroscience and B.A. in Biology from Brandeis University, and a M.S. in Marine Biology from Northeastern University, through the Three Seas Program.
PhD Student - Full C.V.
I received my B.S. in Biology from Tarleton State University and my M.S. in Wildlife Ecology from Texas State University. My research interests are very broad including nearly every aspect of ecology. However, my current research involves sampling water quality, plant cover and species richness, and soil parameters along with other environmental factors at a wastewater treatment plant’s assimilation wetland in order to study the effects of secondarily treated wastewater on a freshwater wetland habitat. The goal of this research is to objectively assess this type of wetland’s environmental impacts and functionality to better understand their feasibility and effective use.
MS Student - Full C.V.
My research interest primarily focus on understanding how anthropogenic disturbances are affecting coastal populations. During my time here in the Nelson Lab, I plan to use stable isotopes to better understand how trophic systems in the Gulf of Mexico are responding to the alteration of habitat structure, caused by sand dredging. I've recently earned a B.S. in Biology from the University of Louisiana at Lafayette. In the future, I hope to become a part of the link that connects science with the community.
MS Student - Full C.V.
I first became associated with the Nelson lab as a summer REU with the Marine Biological Laboratory studying fish ecology and salt marsh food web dynamics at the Plum Island LTER site. I have since earned a B.S. in Environmental Science from Western Washington University and will transition into biogeochemistry for my M.S. I plan to study the impacts of sand dredging on microphytobenthic communities with the BOEM Ship Shoal project. My generalized interests include the economic implications of ecosystem damage and failure for the human industry in addition to the applications of ecosystem science beyond the scope of strictly academic research.
