Mark Vandever is a Rangeland Management Specialist at the Fort Collins Science Center stationed in northern Colorado. Since 2005, his research has focused on the impacts of Farm Bill programs on wildlife habitat across the Great Plains. Other research includes plant-pollinator relationships, environmental stressors to amphibians, and vegetation responses to land management practices.

Science and Products
Agricultural land use accounts for over 50 percent of the surface area of the contiguous United States. How these lands are managed has direct and indirect implications for wildlife, water quality, and air quality in terrestrial, aquatic, and marine ecosystems locally and far beyond their extent.
Exploring the amphibian exposome in an agricultural landscape using telemetry and passive sampling
This is the first field study of its kind to combine radio telemetry, passive samplers, and pesticide accumulation in tissues to characterize the amphibian exposome as it relates to pesticides. Understanding how habitat drives exposure in individuals (i.e., their exposome), and how that relates to individual health is critical to managing species...Swanson, Jennifer E.; Muths, Erin L.; Pierce, Clay; Dinsmore, Stephen J.; Vandever, Mark; Hladik, Michelle; Smalling, Kelly L.
Placement of intracoelomic radio transmitters and silicone passive sampling devices in northern leopard frogs (Lithobates pipiens)
Historically, wetland toxin exposure studies have relied on single time point samples from stationary sampling devices. Development of passive sampling devices (PSDs) that can be attached to individual animals within wetland habitats has greatly improved in recent years, presenting an innovative sampling technology that can potentially yield...Yaw, Taylor; Swanson, Jennifer E.; Pierce, Clay; Muths, Erin L.; Smalling, Kelly L.; Vandever, Mark; Zaffarano, Bianca Anne
Amphibians, pesticides, and the amphibian chytrid fungus in restored wetlands in agricultural landscapes
Information on interactions between pesticide exposure and disease prevalence in amphibian populations is limited, especially from field data. Exposure to certain herbicides and insecticides has the potential to decrease the immune response in frogs, which can potentially lead to increased abundance of Batrachochytrium dendrobatidis (Bd) zoospores...Reeves, Rebecca A.; Pierce, Clay; Vandever, Mark; Muths, Erin L.; Smalling, Kelly L.
Exposure of native bees foraging in an agricultural landscape to current-use pesticides
The awareness of insects as pollinators and indicators of environmental quality has grown in recent years, partially in response to declines in honey bee (Apis mellifera) populations. While most pesticide research has focused on honey bees, there has been less work on native bee populations. To determine the exposure of native bees to pesticides,...Hladik, Michelle; Vandever, Mark W.; Smalling, Kelly L.
Restored agricultural wetlands in Central Iowa: habitat quality and amphibian response
Amphibians are declining throughout the United States and worldwide due, partly, to habitat loss. Conservation practices on the landscape restore wetlands to denitrify tile drainage effluent and restore ecosystem services. Understanding how water quality, hydroperiod, predation, and disease affect amphibians in restored wetlands is central to...Reeves, Rebecca A.; Pierce, Clay; Smalling, Kelly L. ; Klaver, Robert W.; Vandever, Mark W.; Battaglin, William A.; Muths, Erin L.
Management of conservation reserve program grasslands to meet wildlife habitat objectives
Numerous studies document environmental and social benefits of the Conservation Reserve Program (CRP). This report offers a synopsis of findings regarding effects of establishing CRP conservation practices on the quality and distribution of wildlife habitat in agricultural landscapes. On individual farms, year-round provision of wildlife habitat...Vandever, Mark W.; Allen, Arthur W.
Pesticide concentrations in frog tissue and wetland habitats in alandscape dominated by agriculture
Habitat loss and exposure to pesticides are likely primary factors contributing to amphibian decline in agricultural landscapes. Conservation efforts have attempted to restore wetlands lost through landscape modifications to reduce contaminant loads in surface waters and providing quality habitat to wildlife. The benefits of this increased wetland...Smalling, Kelly L.; Reeves, Rebecca; Muths, Erin L.; Vandever, Mark W.; Battaglin, William A.; Hladik, Michelle; Pierce, Clay L.
Grazing effects on aboveground primary production and root biomass of early-seral, mid-seral, and undisturbed semiarid grassland
Annual/perennial and tall/short plant species differentially dominate early to late successional shortgrass steppe communities. Plant species can have different ratios of above-/below-ground biomass distributions and this can be modified by precipitation and grazing. We compared grazing effects on aboveground production and root biomass in early-...Milchunas, D.G.; Vandever, M.W.
Allelopathic cover crop prior to seeding is more important than subsequent grazing/mowing in grassland establishment
The effects of grazing, mowing, and type of cover crop were evaluated in a previous winter wheat–fallow cropland seeded to grassland under the Conservation Reserve Program in eastern Colorado. Prior to seeding, the fallow strips were planted to forage sorghum or wheat in alternating strips (cover crops), with no grazing, moderate to heavy grazing...Milchunas, Daniel G.; Vandever, Mark W.; Ball, Leonard O.; Hyberg, Skip
Fort Collins Science Center- Policy Analysis and Science Assistance Branch : Integrating social, behavioral, economic and biological sciences
The Fort Collins Science Center's Policy Analysis and Science Assistance (PASA) Branch is a team of approximately 22 scientists, technicians, and graduate student researchers. PASA provides unique capabilities in the U.S. Geological Survey by leading projects that integrate social, behavioral, economic, and biological analyses in the context of...
Integrating Agriculture and Conservation
The USGS produces the needed science-based information to guide management actions and policy decisions that support wildlife habitat and other environmental services compatible with USDA conservation goals and farm operations. The Policy Analysis and Science Assistance Branch of the Fort Collins Science Center (FORT) has conducted research...Vandever, Mark W.
