Cattle Resource Selection On Late Fall Sagebrush Steppe Habitat In Idaho, United States, Larry Cole Kempton, April Hulet, Jim Sprinkle, Randy Larsen, Jameson Brennan, Dan Lauritzen, Sawyer Fonnesbeck, Justin Hatch
Library/Life Sciences Undergraduate Poster Competition 2024
Introduction Targeted cattle grazing is increasingly recognized as an effective method for controlling invasive grasses like cheatgrass in sagebrush-steppe ecosystems1. However, there's a lack of understanding about cattle distribution and their preference for invasives during the dormant season. One statistical model that provides insights into cattle distribution and the selection of resources (e.g., vegetation) is the Resource Selection Function (RSF) model2. Our research objective is to utilize a resource selection function to predict the probability of cattle selecting a particular location, in our case areas with higher cheatgrass abundance, based on environmental variables. The development of a resource selection function …

Gibberellic Acid Data, Amber Johnson
ScholarsArchive Data
This dataset contains plant emergence and survival data collected from a field study which focused on overcoming seed dormancy. Seed dormancy can present a challenge within a restoration scenario where rapid establishment is required. Soaking seeds in gibberellic acid (GA3) can overcome dormancy and increase germination but this treatment may not be effective outside the laboratory. An easier and potentially more effective method to apply this hormone is to coat seeds with a GA3-impregnated polymer, which provides a slow release of GA3. Seed dormancy can also be mitigated by creating a favorable microsite with …
Movements And Space-Use Of Female Greater Sage-Grouse (Centrocercus Urophasianus) During Nesting And Breeding Seasons, Drew W. Retherford
Movements And Space-Use Of Female Greater Sage-Grouse (Centrocercus Urophasianus) During Nesting And Breeding Seasons, Drew W. Retherford
Theses and Dissertations
Greater sage-grouse (Centrocercus urophasianus) are a species of conservation concern throughout their range including the state of Idaho. Little is known about the size of areas used by female sage-grouse during the breeding and nesting seasons, fidelity of females to those areas, or fidelity of female sage-grouse to specific leks or nest sites. The recent miniaturization of global positioning system (GPS) transmitting devices allows for a more thorough analysis of this behavior. We placed GPS transmitters on 234 female sage-grouse in Idaho, USA, from 2015 to 2019. We monitored 145 nest attempts, 15 of which occurred in consecutive years, from …
Space Use, Resource Selection, And Survival Of Reintroduced Bighorn Sheep, Rusty Wade Robinson
Space Use, Resource Selection, And Survival Of Reintroduced Bighorn Sheep, Rusty Wade Robinson
Theses and Dissertations
Successful management of bighorn sheep depends on understanding the mechanisms responsible for population growth or decline, habitat selection, and utilization distribution after translocations. We studied a declining population of desert bighorn sheep in the North San Rafael Swell, Utah to determine birthdates of neonates, demographics, limiting factors, population size, probable cause of death, production, and survival. We documented 19 mortalities attributed to a variety of causes including cougar predation (n = 10, 53%), bluetongue virus (n = 2, 11%), reproductive complications (n = 2, 11%), hunter harvest (n = 1, 5%), and unknown (n = 4, 21%). Annual survival of …
