Mike Colvin, PhD
Dr. Mike Colvin is a Research Ecologist at the Columbia Environmental Research Center
Dr. Mike Colvin received a Ph.D. from Iowa State University. He was a postdoctoral scholar at Oregon State University, where he trained in using structured decision-making and adaptive management of natural resources. As an assistant and associate professor at Mississippi State University, he taught courses in fisheries science, fisheries management, and natural resource decision-making. His research group applied decision-making approaches to conserving and managing aquatic resources. He joined the USGS in 2022 as a research ecologist.
Mike’s research efforts integrate management actions, monitoring, and research with structured decision-making and adaptive management. Current research areas include
- Supporting science components and decision analysis for endangered pallid sturgeon in the Missouri River,
- Adaptive management program development for invasive carps,
- Developing decision support tools for species status assessments of aquatic species in the southeast US, and
- Applying structured decision-making and adaptive management to natural resource problems.

Dike Fields and Macrohabitats of the Lower Missouri River Dike Fields and Macrohabitats of the Lower Missouri River
This project summarizes broad, two-dimensional spatial availability of fish habitat across the Lower Missouri River (from its confluence with the Big Sioux River near Sioux City, Iowa downstream to its confluence with the Mississippi River near St. Louis, Missouri). One of the main objectives of the project was to delineate and categorize dike fields, which we define as areas directly...

Hydrologic connectivity in floodplain systems: A multiscale review of concepts, metrics and management Hydrologic connectivity in floodplain systems: A multiscale review of concepts, metrics and management
Hydrologic connectivity (HC), particularly in floodplain systems, is pivotal in regulating ecosystem services by facilitating the movement of nutrients, sediments, chemicals, and biota. However, human interventions such as dam construction, levee installation, water management practices, and alterations in vegetation have significantly disrupted natural HC patterns globally. To provide a...

Evaluating deterrent locations and sequence in the Tennessee and Cumberland Rivers and the Tennessee–Tombigbee Waterway to minimize invasive carp occupancy and abundance Evaluating deterrent locations and sequence in the Tennessee and Cumberland Rivers and the Tennessee–Tombigbee Waterway to minimize invasive carp occupancy and abundance
Invasive carps, specifically silver carp (Hypophthalmichthys molitrix), bighead carp (H. nobilis), grass carp (Ctenopharyngodon idella), and black carp (Mylopharyngodon piceus), have proliferated in the Mississippi River Basin owing to escapes from aquaculture facilities and intentional releases. In the Water Resources and Development Act (WRDA) of 2020 Sec. 509, Congress directed the U...

A review of standardization in Mississippi’s multidecadal inland fisheries monitoring program A review of standardization in Mississippi’s multidecadal inland fisheries monitoring program
Standardizing data collection, management, and analysis processes can improve the reliability and efficiency of fisheries monitoring programs, yet few studies have examined the operationalization of these tasks within agency settings. We reviewed the Mississippi Department of Wildlife, Fisheries, and Parks, Fisheries Bureau’s inland recreational fisheries monitoring program—a 30+-year...

Black Carp Mylopharyngodon piceus were imported into the United States in the 1970s and 1980s for use in aquaculture; escape occurred and reported wild captures increased. Lacking species-specific capture methods, we assessed fisheries dependent incidental Black Carp catches for a common method, hoop nets, by kernel density analysis to identify an area of increased reporting and compare...

Confluence of time and space: An innovation for quantifying dynamics of hydrologic floodplain connectivity with remote sensing and GIS Confluence of time and space: An innovation for quantifying dynamics of hydrologic floodplain connectivity with remote sensing and GIS
Hydrologic connectivity is a crucial determinant of aquatic ecosystem services, governing the exchange of nutrients, sediments, chemicals, and biota. Various indices and metrics exist for quantifying hydrologic connectivity across diverse environments and scales. However, existing methodologies often fail to adequately capture lateral connectivity between floodplain lakes and streams...

Connectivity patterns between floodplain lakes and neighboring streams in the historical floodplain of the Lower Mississippi River Connectivity patterns between floodplain lakes and neighboring streams in the historical floodplain of the Lower Mississippi River
Hydrologic connectivity, the network of water pathways linking aquatic habitats, is vital for the exchange of organisms and abiotic materials between rivers and adjacent waterbodies. This study quantified hydrologic connectivity for 1,283 lakes in the Lower Mississippi River floodplain using satellite imagery, streamgauge data, and geospatial information. We aimed to assess connection...

Spatial distribution patterns of invasive silver carp can inform removal efforts in an oxbow lake of the Mississippi River Spatial distribution patterns of invasive silver carp can inform removal efforts in an oxbow lake of the Mississippi River
Oxbow lakes are highly productive waterbodies that host multiple life stages of many freshwater aquatic species. These lakes also provide foraging and rearing habitat to the invasive silver carp (Hypophthalmichthys molitrix) enabling populations to grow in biomass and abundance that can add propagule pressure to connected waterways and oxbows within the Mississippi River Basin...

Using resiliency, redundancy, and representation in a Bayesian belief network to assess imperilment of riverine fishes Using resiliency, redundancy, and representation in a Bayesian belief network to assess imperilment of riverine fishes
Conservation prioritization frameworks are used worldwide to identify species at greatest risk of extinction and to allocate limited resources across regions, species, and populations. Conservation prioritization can be impeded by ecological knowledge gaps and data deficiency, especially in freshwater species inhabiting highly complex aquatic ecosystems. Therefore, we developed a...

Influence of invasive bigheaded carps on abundance of Gizzard Shad in the Tennessee River Influence of invasive bigheaded carps on abundance of Gizzard Shad in the Tennessee River
ObjectiveThe Tennessee River basin and its cascade of reservoirs are home to some of the most diverse freshwater fish assemblages in the world.
