Ecology
The department's teaching and research addresses critical ecological and natural resources issues for Montana, but also tackles fundamental and applied questions around the globe. Undergraduate programs within the department include Fish & Wildlife Management and Ecology, Conservation Biology and Ecology, Organismal Biology, and Biology Teaching. Graduate programs (M.S. and P.hD.) include Fish & Wildlife Management or Biology and Biological Sciences and an intercollege PhD in Ecology and Environmental Sciences.

Effects of Climate-Related Stream Factors on Patterns of Individual Summer Growth of Cutthroat Trout
(2019-01)Coldwater fishes are sensitive to abiotic and biotic stream factors, which can be influenced by climate. Distributions of inland salmonids in North America have declined significantly, with many of the current strongholds ... -
Maladaptive nest-site selection by a sagebrush dependent species in a grazing-modified landscape
(2019-04)Animals are expected to select habitats that maximize their fitness over evolutionary time scales. Yet in human-modified landscapes, habitat selection might not always lead to increased fitness because animals undervalue ... -
Crayfish ecosystem engineering effects on riverbed disturbance and topography are mediated by size and behavior
(2018-12)Animals that burrow, forage, or produce physical structures can have substantial impacts on transport processes related to erosion. However, the influence of behavior and body size on regulating the magnitude of engineering ... -
Statistical Analysis of Maximally Similar Sets in Ecological Research
(2018-12)Maximally similar sets (MSSs) are sets of elements that share a neighborhood in a high-dimensional space defined by a symmetric, reflexive similarity relation. Each element of the universe is employed as the kernel of a ... -
Checklist of bees (Hymenoptera: Apoidea) from small diversified vegetable farms in south-western Montana
(2019-01)Background: Over three years (2013-2015), we sampled bees using nets and bowl traps on four diversified vegetable farms in Gallatin County, Montana, USA, as part of a study evaluating the use of wildflower strips for ... -
Variation in the vital rates of an Antarctic marine predator: the role of individual heterogeneity
(2018-10)Variation in life-history traits such as lifespan and lifetime reproductive output is thought to arise, in part, due to among-individual differences in the underlying probabilities of survival and reproduction. However, ... -
Using Satellite Data to Support Fieldwork: Can Species Distributions Be Predicted?
(1996-07)Although species extinction has become a global concern during the last decade, our knowledge of species distribution patterns remains limited. If we don't know where a species has existed historically, we cannot determine ... -
Natural Ecosystems I. The Rocky Mountains
(2003-10)This assessment of climate-change effects on Rocky Mountain terrestrial ecosystems is prepare from information generated by a workshop focused on terrestrial systems of the Rocky Mountains, and held in Boulder, CO, on 29-30 ... -
Forest Fragmentation and Matrix Effects: The Matrix Does Matter
(2006-10)When ecologists envision a traditional habitat fragmentation study, they usually conjure up an image of very discrete fragments, perhaps rectangular or even square, surrounded by a matrix of very different, inhospitable ... -
Regal Fritillary and its Host Plant Studied at Neal Smith National Wildlife Refuge (Iowa)
(2000-12)Traditional tallgrass prairie restoration efforts have focused primarily on planting and managing the dominant species of prairie vegetation. Meanwhile, little is known about techniques for restoring prairie insect species, ... -
Butterflies and Continuous Conservation Reserve Program Filter Strips: Landscape Considerations
(2006-11)Filter strips or buffers are areas of grass or other perennial herbaceous vegetation established along waterways to remove contaminants and sediments from agricultural field runoff. In the heavily cultivated regions of the ... -
Butterfly Responses to Prairie Restoration Through Fire and Grazing
(2007-11)The development of land for modern agriculture has resulted in losses of native prairie habitat. The small, isolated patches of prairie habitat that remain are threatened by fire suppression, overgrazing, and invasion by ... -
Butterflies Like Wide Buffer Strips with Tall Native Grasses and
(2007-01)If you want more species of butterflies in your filter strips and other grass buffers, make the buffers wider and plant tall native grasses and broad leaf plants. That’s a key finding of a southwestern Minnesota study on ... -
Butterfly, bee and forb community composition and cross-taxon incongruence in tallgrass prairie fragments
(2008-02)Pollinators provide an important class of ecological services for crop plants and native species in many ecosystems, including the tallgrass prairie, and their conservation is essential to sustaining prairie remnants. In ... -
Changes in Vegetation Structure through Time in a Restored Tallgrass Prairie Ecosystem and Implications for Avian Diversity and Community Composition
(2009-12)Grassland birds are one of the most endangered taxa in temperate North America. Because many species declines have been linked to habitat fragmentation and loss, large-scale prairie restoration projects have the potential ... -
Quantifying lion (Panthera leo) demographic response following a three-year moratorium on trophy hunting.
(2018-05)Factors that limit African lion populations are manifold and well-recognized, but their relative demographic effects remain poorly understood, particularly trophy hunting near protected areas. We identified and monitored ... -
Foraging investment in a long-lived herbivore and vulnerability to coursing and stalking predators
(2018-10)Allocating resources to growth and reproduction requires grazers to invest time in foraging, but foraging promotes dental senescence and constrains expression of proactive antipredator behaviors such as vigilance. We ... -
Nest Success of Yellow Warblers in Willow Habitats: The Role of Surface Water and Snakes
(2004-01)Yellow Warblers (Dendroica petechia) are migratory songbirds found in high abundance in the tall willow (Salix boothii) habitats of Grand Teton National Park (GTNP). Willows are found in wet soils with high water tables ... -
Quantifying Early Indicators of Global Climate Change
(2006-01)One of the more significant voids remaining in our scientific understanding of global climate change is the relationship between climate change and the resulting changes expected in ecological communities. Because a large ... -
Montane Meadow Butterfly Species Distributions in the Greater Yellowstone Ecosystem
(2006-01)The composition of butterfly communities is a good indicator of changing environmental conditions. Butterflies have tight associations with the plant community due to their dependence on plants throughout their life history. ...
