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.

Vegetation Distribution and Production in Rocky Mountain Climates—with Emphasis on Whitebark Pine
(International Workshop on Subalpine Stone Pines and Their Environment: the Status of Our Knowledge, 1992)The distribution and production of vegetation on the altitudinal J gradient (grassland-forest-alpine) was plotted against climatic parameters to evaluate hypothetical controlling factors. (1) Whitebark pine (Pinus albicaulis) ... -
Climates Where Stone Pines Grow, A Comparison
(International Workshop on Subalpine Stone Pines and Their Environment: the Status of Our Knowledge, 1992)------ Abstract-While stone pine climates are similar adapted to relatively moderate climates may be excluded from, species the ranges of congeners by more severe climates, and species with longer warm-moiBt growing ... -
Restoration Potential of Bighorn Sheep in a Prairie Region
(2020-07)Efforts to recover Rocky Mountain bighorn sheep (Ovis canadensis canadensis) throughout western North America have had limited success with the majority of current populations remaining in small and isolated areas on a ... -
Distribution of Exotic Plants in the N. Rocky Mountains by Environmental Type and Disturbance Condition
(Montana State Univeristy, 1989-06)This report lists seventy-three exotic species found in a systematic sampling of major environmental zones of the Rocky Mountains between the Canadian border and central Wyoming. For each exotic it states the regional ... -
PLANTS ESTABLISHING IN ROCKY MOUNTAIN ENVIRONMENTS-- a manual for choosing native species for revegetation
(Montana State University, 1995)Species which have established naturally on a disturbed site in a given environment-- climate and disturbance level (defined below)-- are good candidates for revegetation plantings in that environment. On this basis we ... -
Root distribution and soil water regimes in nine habitat types of the northern Rocky Mountains
(Colorado State University, 1977)Root distribution and the annual cycle of' soil water availability were measured in nine habitat types of the northern Rocky Mountains. Water stress periods became progressively longer under Abies lasiooarpa forests, Populus ... -
Cone production in Pinus albicaulis Forests
(Inland Mountain West Symposium, 1985-08)Whitebark pine cone production was estimated for a 6 to 8 year period in each of 29 stands widespread in.the northern.Rocky Mountains. 1) One-time sampling was possible since the estimate was m2de by multiplying the number ... -
Changes in soils along a vegetational (altitudinal) gradient of the northern Rocky Mountains
(Soil Science Society of America, 1979)As one moves from the warm dry plains of eastern Montana to the cool moist peaks of the northern Rocky Mountains he might pass through a series of native vegetation types: Bouteloua gracilis, Agropyron spicatum, Featuca ... -
Resource Supply Governs the Apparent Temperature Dependence of Animal Production in Stream Ecosystems
(2020-10)Rising global temperatures are changing how energy and materials move through ecosystems, with potential consequences for the role of animals in these processes. We tested a central prediction of the metabolic scaling ... -
Bibliography of Montana vegetation description
(1988)Listed in alphabetical order by author are 549 references to literature that describes the native vegetation of Montana. This updates the 1965 list of Habeck and Hartley. A keyword subject index is included. -
Biomass of fifty conifer forests and nutrient exports associated with their harvest
(1977)Biomasses of climax Rocky Mountain forests studied ranged from less than 50 to more than 300 tons/ha. Total biomass was approximately 1.5 times the biomass of normally merchantable boles. When compared with conventional ... -
Environmental and Climatic Factors Affecting Winter Hypoxia in a Freshwater Lake: Evidence for a Hypoxia Refuge and for Re-oxygenation Prior to Spring Ice Loss
(2020-09)Low dissolved oxygen, or hypoxia, is a common phenomenon in ice-covered lakes in winter. We measured dissolved oxygen (DO) before, during, and after ice-over to characterize the timing, severity, and spatial variability ... -
Toward spatio-temporal delineation of positive interactions in ecology
(2020-09)Given unprecedented rates of biodiversity loss, there is an urgency to better understand the ecological consequences of interactions among organisms that may lost or altered. Positive interactions among organisms of the ... -
Benthic Suffocation of Invasive Lake Trout Embryos by Fish Carcasses and Sedimentation in Yellowstone Lake
(2020-10)Introduced Lake Trout Salvelinus namaycush threaten native Yellowstone Cutthroat Trout Oncorhynchus clarkii bouvieri in Yellowstone Lake, Yellowstone National Park, where gill nets have been used to suppress subadult and ... -
Wildflower Seed Sales as Incentive for Adopting Flower Strips for Native Bee Conservation: A Cost-Benefit Analysis
(2019-07)Improving pollinator habitat on farmlands is needed to further wild bee conservation and to sustain crop pollination in light of relationships between global declines in pollinators and reductions in floral resources. One ... -
High-severity wildfire limits available floral pollen quality and bumble bee nutrition compared to mixed-severity burns
(2019-12)High-severity wildfires, which can homogenize floral communities, are becoming more common relative to historic mixed-severity fire regimes in the Northern Rockies of the U.S. High-severity wildfire could negatively affect ... -
Food web controls on mercury fluxes and fate in the Colorado River, Grand Canyon
(2020-05)Mercury (Hg) biomagnification in aquatic food webs is a global concern; yet, the ways species traits and interactions mediate these fluxes remain poorly understood. Few pathways dominated Hg flux in the Colorado River ... -
Trampling Effects on Vegetation of the Trail Corridors of North Rocky Mountain Forests
(1974-08)The management of trails should be based on knowledge of the effects of humans on them; most of the available information has been reviewed by Speight (1973), Stankey & Lime (1973), and Liddle (1975). Observations of ... -
Tracking the migration of Pacific Golden-Plovers from nonbreeding grounds at Moorea, French Polynesia, using Pinpoint GPS-Argos tags
(2020-04)We used Pinpoint GPS-Argos tags to track migration of Pacific Golden-Plovers Pluvialis fulva in 2017 and 2018 from Moorea Island, at the extreme southeastern edge of the species’ winter range. Of 20 tagged birds, 13 uploaded ...
