expanding the science of river ecology
Team
Principal Investigator: Sandra Bibiana Correa
I am originally from Colombia (South America), where I earned a BS degree in Biology from the Universidad del Valle. Later, I graduated with a MS degree from the University of Florida and a Ph.D. degree from Texas A&M University. Throughout my undergraduate, graduate and post-doctoral research, I devoted myself to investigate fish ecology in large tropical rivers including how seasonality and structural complexity influence habitat use, how pulses in food resource availability mediate species coexistence, and how fruit-eating fishes contribute to the seed dispersal and natural regeneration of forested wetlands.
Graduate Students
Karold Coronado (Ph. D. student)
I am from Colombia (South America), where I obtained a B.S. in Environmental Engineering and M.S. in Environmental Engineering from the National University of Colombia, Palmira campus. Before coming to MSU, I worked in professional positions studying marine organisms and ecosystems from a spatial approach. Previous work includes studying the effect of climate change on the spatial distribution of commercial fishes in the Colombian Pacific Ocean, detecting algal blooms in the Colombian Caribbean Sea using remote sensing and GIS tools, and evaluating ecosystem health in coastal zones.
At Mississippi State University I am investigating the drivers influencing the spatial distribution of the Serrasalmidae family (pacus and piranhas) in the Amazon basin river. I am especially interested in exploring the relationship between flooded forest characteristics and environmental change with spatial aggregation patterns and diversity of frugivorous fish species. In the future, I would like to keep investigating macroecological patterns of freshwater and marine species.
Undergraduate Students
Grant Peterson (College of Forest Resources Undergraduate Research Scholar)
With Dr. Correa’s supervision, I am leading a collaborative undergraduate research project. The goal of the project is to determine whether bottomland forests represent a critical habitat for fish in early life stages. The project will utilize GIS technology, light traps, multiple identification methods, and other tools to sample juvenile fish species in these flooded forest ecosystems.
After I graduate, I intend to pursue one or multiple graduate degrees. I am interested in conservation biology, evolutionary biology, ecology, and conservation education.
Autumn Caroll (College of Forest Resources Undergraduate Research Scholar)
Under Dr. Correa’s guidance, I co-lead an undergraduate research project at Mississippi State University. The project’s goal is to determine if bottomland hardwood forests are critical in supporting juvenile and larval fishes. The project utilizes GIS technology, light traps, fyke nets, identifying and handling fish, as well as collecting water quality measurements.
After graduation, I plan to attend a veterinary school where I will specialize in marine animal medicine.
Former Lab members
Lucelia Nobre-Carvalho (Post-doctoral Scholar)
I am originally from Brazil where I am an Associate Professor at the Federal University of Mato Grosso and coordinate the Tropical Ichthyology Laboratory (www.litufmtsinop.com). I earned a BS degree in Biology a Ph.D. degree in Biology of Freshwaters and Continental Fisheries, both from the Universidade Federal de Uberlândia. My research focusses on investigating interactions between fishes and abiotic environmental factors using descriptive, comparative, and experimental approaches.
Topics of interest include fish behavior, fish-forest interactions, and the effects of parasites on fish behavior. Our work is strongly field-oriented, with studies conducted in streams and rivers of the Tapajos Basin within the Amazon region.
At Mississippi State University, I analyzed a large dataset from the Teles Pires River, focusing on fish-forest interactions and seed dispersal and seed predation by fish. See recent publications (Santos et al. 2020, Carvalho et al. 2021).
Laura Horowitz (M.S. student)
At Mississippi State University, I studied the fishing mortality of tarpon in laboratory settings and coastal lagoons in Puerto Rico. In the lab, I was able to mimic fishing experiences to determine the stress of tarpon and assess proper aquaculture techniques for tarpon. In Puerto Rico, I partnered with Caribbean Fishing Adventures, taking blood samples to determine how stressed the caught fish are and tagging and tracking caught fish to assess post-release mortality with acoustic telemetry. After graduation, I am pursuing a job where I get to be out in the field.
Conner Owens (M.S. student)
At Mississippi State University, I had the opportunity to research how fish assemblages change over time and space in an extremely unique and dynamic river-floodplain system, the Pascagoula River, Mississippi. My research demonstrated that bottomland hardwood forests provide habitat for more and unique fish species than the main river channel. These forests serve as climate refugia for fish by maintaining cooler water during the hot summer months.
I am currently working for the South Carolina Department of Natural Resources, where I continue sampling fish assemblages in unique environments and studying the fascinating world of aquatic ecology!
Adriana Forero (Visiting Scholar, Ph.D. student, Universidad del Tolima, Ibague, Colombia)
I am from Colombia (South America), where I earned a B.S. degree in Biology and M.S. in Biological Sciences from the Universidad del Tolima. Nowadays, I am a Ph.D. student of the Biological Sciences doctoral program and I am a member of the Zoology Research Group at the same University. My research evaluates the effect of invasive rainbow trout (Oncorhynchus mykiss) in streams, with an emphasis on the trophic ecology of fish. My works have been oriented toward knowing the aquatic ecosystems present in the department of Tolima and the effects that humans are having on them.
At Mississippi State University, I conducted analysis of stable isotope, diet, and community data to establish trophic relationships between native high mountain fish species and the invasive trout. Upon graduation, I plan to continue in an academic career and teach at a research university.
Nick Stewart (College of Forest Resources Undergraduate Research Scholar)
At Mississippi State University, I led an undergraduate research project, with Dr. Correa’s guidance, looking at potential changes in fish distributions along local coastal rivers driven by sea-level rise. This project used survey data of Local Ecological Knowledge from fishermen and anglers to assess change. In addition, I participated in field research assisting graduate student Conner Owens in sampling fishes with different gear types, identifying and handling fish, and collecting water quality measurements.
After graduation, I continued working with Dr. Correa’s lab. I am leading another project estimating the age of bowfin fish using hard structures such as the gular plate and pectoral fin rays. Bowfin fish is an ancient predatory fish species abundant in floodplain forests. My research aims to understand how long individuals persist in flooded forest ecosystems and thereby their influence on food webs.
I am currently working as a research assistant at the Gulf Coast Research Laboratory of the University of Southern Mississippi.
Austin Reese (College of Forest Resources Undergraduate Research Scholar)
I started working with Dr. Sandra Correa and Dr. Joshua Granger (Department of Forestry) in the fall of 2019. During the 2019-2020 academic year, I helped determine the age of tree cores taken from floodplain forest sites along the Pascagoula River, Mississippi. I was able to present the findings from the research at an undergraduate symposium in Spring 2020. Between 2020 and 2021, I conducted independent research to investigate the relationship between mosses grown on trees in flooded forests and fish at the Noxubee Wildlife Refuge near the MSU campus. This ongoing project will sample the aquatic invertebrates associated with the mosses, which in turn are fish prey.
