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.

Assessment of adult pallid sturgeon fish condition, Lower Missouri River—Application of new information to the Missouri River Recovery Program Assessment of adult pallid sturgeon fish condition, Lower Missouri River—Application of new information to the Missouri River Recovery Program
During spring 2015, Nebraska Game and Parks Commission (NGPC) biologists noted that pallid sturgeon (Scaphirhynchus albus) were in poor condition during sampling associated with the Pallid Sturgeon Population Assessment Project and NGPC’s annual pallid sturgeon broodstock collection effort. These observations prompted concerns that reduced fish condition could compromise reproductive...

Preparing future fisheries professionals to make good decisions Preparing future fisheries professionals to make good decisions
Future fisheries professionals will face decision-making challenges in an increasingly complex field of fisheries management. Though fisheries students are well trained in the use of the scientific method to understand the natural world, they are rarely exposed to structured decision making (SDM) as part of an undergraduate or graduate education. Specifically, SDM encourages users (e.g...

A hidden-process model for estimating prespawn mortality using carcass survey data A hidden-process model for estimating prespawn mortality using carcass survey data
After returning to spawning areas, adult Pacific salmon Oncorhynchus spp. often die without spawning successfully, which is commonly referred to as prespawn mortality. Prespawn mortality reduces reproductive success and can thereby hamper conservation, restoration, and reintroduction efforts. The primary source of information used to estimate prespawn mortality is collected through...

Missouri River Scaphirhynchus albus (pallid sturgeon) effects analysis—Integrative report 2016 Missouri River Scaphirhynchus albus (pallid sturgeon) effects analysis—Integrative report 2016
The Missouri River Pallid Sturgeon Effects Analysis was designed to carry out three components of an assessment of how Missouri River management has affected, and will affect, population dynamics of endangered Scaphirhynchus albus (pallid sturgeon): (1) collection of reliable scientific information, (2) critical assessment and synthesis of available data and analyses, and (3) analysis of...

Innate and adaptive immune responses in migrating spring-run adult chinook salmon, Oncorhynchus tshawytscha Innate and adaptive immune responses in migrating spring-run adult chinook salmon, Oncorhynchus tshawytscha
Adult Chinook salmon (Oncorhynchus tshawytscha) migrate from salt water to freshwater streams to spawn. Immune responses in migrating adult salmon are thought to diminish in the run up to spawning, though the exact mechanisms for diminished immune responses remain unknown. Here we examine both adaptive and innate immune responses as well as pathogen burdens in migrating adult Chinook...

This report documents a process of filtering of hypotheses that relate Missouri River Scaphirhynchus albus (pallid sturgeon) population dynamics to management actions including flow alterations, channel reconfigurations, and pallid sturgeon population augmentation. The filtering process was a partnership among U.S. Geological Survey, U.S. Army Corps of Engineers, and U.S. Fish and...

A food web modeling analysis of a Midwestern, USA eutrophic lake dominated by non-native Common Carp and Zebra Mussels A food web modeling analysis of a Midwestern, USA eutrophic lake dominated by non-native Common Carp and Zebra Mussels
Food web modeling is recognized as fundamental to understanding the complexities of aquatic systems. Ecopath is the most common mass-balance model used to represent food webs and quantify trophic interactions among groups. We constructed annual Ecopath models for four consecutive years during the first half-decade of a zebra mussel invasion in shallow, eutrophic Clear Lake, Iowa, USA, to...

This report documents the process of developing and refining conceptual ecological models (CEMs) for linking river management to pallid sturgeon (Scaphirhynchus albus) population dynamics in the Missouri River. The refined CEMs are being used in the Missouri River Pallid Sturgeon Effects Analysis to organize, document, and formalize an understanding of pallid sturgeon population...

Occupancy modeling for improved accuracy and understanding of pathogen prevalence and dynamics Occupancy modeling for improved accuracy and understanding of pathogen prevalence and dynamics
Most pathogen detection tests are imperfect, with a sensitivity 100%, thereby resulting in the potential for a false negative, where a pathogen is present but not detected. False negatives in a sample inflate the number of non-detections, negatively biasing estimates of pathogen prevalence. Histological examination of tissues as a diagnostic test can be advantageous as multiple pathogens...

Semi-discrete biomass dynamic modeling: an improved approach for assessing fish stock responses to pulsed harvest events Semi-discrete biomass dynamic modeling: an improved approach for assessing fish stock responses to pulsed harvest events
Continuous harvest over an annual period is a common assumption of continuous biomass dynamics models (CBDMs); however, fish are frequently harvested in a discrete manner. We developed semidiscrete biomass dynamics models (SDBDMs) that allow discrete harvest events and evaluated differences between CBDMs and SDBDMs using an equilibrium yield analysis with varying levels of fishing...
