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.

Evaluating regional length limits in freshwater fisheries Evaluating regional length limits in freshwater fisheries
Length limits are often used in recreational fisheries management to prevent overharvest and manipulate fish size distributions. These regulations are ideally customized to meet water-specific stock dynamics and fishery objectives. However, in districts with numerous discrete waters, fisheries are commonly managed with a universal regional regulation. Evaluating alternative regional...

Selection of habitat-enhancing plants depends on predator-prey interactions Selection of habitat-enhancing plants depends on predator-prey interactions
Shallow areas of drawdown reservoirs are often devoid of adequate fish habitat due to degradation associated with unnatural and relatively invariable cycles of exposure and flooding. One method of enhancing fish habitat in these areas is to sow exposed shorelines with agricultural plants to provide structure once flooded. It remains unclear if some plants may be more suitable than others...

Catch rates for sturgeon chubs and sicklefin chubs in the Upper Missouri River 2004–2016 and correlations with biotic and abiotic variables Catch rates for sturgeon chubs and sicklefin chubs in the Upper Missouri River 2004–2016 and correlations with biotic and abiotic variables
A multiweek standardized sampling regime during 2004–2016 in a 60-km reach of the Upper Missouri River assessed reproduction and catch rates for Sturgeon Chub Macrhybopsis gelida and Sicklefin Chub Macrhybopsis meeki. We sampled age-0 Macrhybopsis (primarily Sturgeon Chubs, but potentially including Sicklefin Chubs) all years to indicate successful reproduction, but noted an inverse...

Themes of contemporary inland fisheries goals Themes of contemporary inland fisheries goals
Goals are important for the effective execution of public trust responsibilities by state inland fisheries bureaus, but formulating meaningful goals is not simple. Often bureaus look to their past and to their sister bureaus in neighboring states when crafting goals for their own freshwater resources. Herein, we review the goal themes of fisheries bureaus using publicly available...

Pallid sturgeon seasonal habitat selection in a large free-flowing river, the lower Mississippi River Pallid sturgeon seasonal habitat selection in a large free-flowing river, the lower Mississippi River
Pallid sturgeon Scaphirhynchus albus (Forbes & Richardson, 1905, Bulletin of the Illinois State Laboratory of Natural History, 1905, 7, 37) are an endangered riverine sturgeon native to the Mississippi and Missouri rivers, and declining numbers have been attributed to multiple stressors, including habitat loss and alteration. The lower Mississippi River provides a useful context to...

A seasonal population matrix model of the Caribbean Red-tailed Hawk Buteo jamaicensis jamaicensis in eastern Puerto Rico A seasonal population matrix model of the Caribbean Red-tailed Hawk Buteo jamaicensis jamaicensis in eastern Puerto Rico
Reliable estimates of life history parameters and their functional role in animal population trajectories are critical, yet often missing, components in conservation and management. We developed seasonal matrix population models of the Red-tailed Hawk Buteo jamaicensis jamaicensis in the upper and lower forests of the Luquillo Mountains, Puerto Rico, to describe the influence of early...

A food web modeling assessment of Asian Carp impacts in the Middle and Upper Mississippi River, USA A food web modeling assessment of Asian Carp impacts in the Middle and Upper Mississippi River, USA
The invasion of non-native fishes has caused a great detriment to many of our native fishes. Since the introduction of invasive carps, such as Silver, Bighead, Common and Grass Carp, managers and researcher have been struggling to remove these species while also hypothesizing the detriment of further invasion. This study developed a food web model of four locations on the Mississippi...

Overview and progress of the pallid sturgeon assessment framework redesign process Overview and progress of the pallid sturgeon assessment framework redesign process
The Pallid Sturgeon Population Assessment Program (PSPAP) was initiated in 2003, and full implementation began in 2006, to monitor the trend of Scaphirhynchus albus (pallid sturgeon) and native fish communities in the Upper and Lower Missouri River Basins. The original PSPAP (v. 1.0) was a catch-effort based monitoring program where population abundance and trend were monitored using a...

Identifying optimal hauling densities for adult Chinook Salmon trap and haul operations Identifying optimal hauling densities for adult Chinook Salmon trap and haul operations
Trap and haul programs are used to conserve fish populations by circumventing high mortality locations or events, and enhancing population abundance by reintroducing fish to historical habitats and mitigating for fish passage limitations. Spring run Chinook Salmon are transported in trucks upstream of barrier dams in Willamette River Tributaries as part of fish conservation efforts. Fish

Bend-scale geomorphic classification and assessment of the Lower Missouri River from Sioux City, Iowa, to the Mississippi River for application to pallid sturgeon management Bend-scale geomorphic classification and assessment of the Lower Missouri River from Sioux City, Iowa, to the Mississippi River for application to pallid sturgeon management
Management actions intended to increase growth and survival of pallid sturgeon (Scaphirhynchus albus) age-0 larvae on the Lower Missouri River require a comprehensive understanding of the geomorphic habitat template of the river. The study described here had two objectives relating to where channel-reconfiguration projects should be located to optimize effectiveness. The first objective...

Dietary plasticity in a nutrient-rich system does not influence brown bear (Ursus arctos) body condition or denning Dietary plasticity in a nutrient-rich system does not influence brown bear (Ursus arctos) body condition or denning
Behavioral differences within a population can allow use of a greater range of resources among individuals. The brown bear (Ursus arctos) is a generalist omnivore that occupies diverse habitats and displays considerable plasticity in food use. We evaluated whether brown bear foraging that resulted in deviations from a proposed optimal diet influenced body condition and, in turn, denning...

Influences of landscape heterogeneity on home-range sizes of brown bears Influences of landscape heterogeneity on home-range sizes of brown bears
Animal space use is influenced by many factors and can affect individual survival and fitness. Under optimal foraging theory, individuals use landscapes to optimize high-quality resources while minimizing the amount of energy used to acquire them. The spatial resource variability hypothesis states that as patchiness of resources increases, individuals use larger areas to obtain the...
