Sage‐Grouse Breeding And Late Brood‐Rearing Habitat Guidelines In Utah, David K. Dahlgren, Terry A. Messmer, Benjamin A. Crabb, Michel T. Kohl, Shandra Nicole Frey, Eric T. Thacker, Randy T. Larsen, Rick J. Baxter

Wildland Resources Faculty Publications

Delineation, protection, and restoration of habitats provide the basis for endangered and threatened species recovery plans. Species recovery plans typically contain guidelines that provide managers with a scientific basis to designate and manage critical habitats. As such, habitat guidelines are best developed using data that capture the full diversity of ecological and environmental conditions that provide habitat across the species’ range. However, when baseline information, which fails to capture habitat diversity, is used to develop guidelines, inconsistencies and problems arise when applying those guidelines to habitats within an ecologically diverse landscape. Greater sage‐grouse (Centrocercus urophasianus; sage‐ grouse) populations …

Invasive Phragmites Australis Management Outcomes And Native Plant Recovery Are Context Dependent, Christine B. Rohal, Chad R. Cranney, Eric L. G. Hazelton, Karin M. Kettenring

Ecology Center Publications

The outcomes of invasive plant removal efforts are influenced by management decisions, but are also contingent on the uncontrolled spatial and temporal context of management areas. Phragmites australis is an aggressive invader that is intensively managed in wetlands across North America. Treatment options have been understudied, and the ecological contingencies of management outcomes are poorly understood. We implemented a 5‐year, multi‐site experiment to evaluate six Phragmites management treatments that varied timing (summer or fall) and types of herbicide (glyphosate or imazapyr) along with mowing, plus a nonherbicide solarization treatment. We evaluated treatments for their influence on Phragmites and native plant …

Utah Teachers’ Perceptions Of Teaching Genetic Engineering In The Classroom, Olivia Horning Hile, Tyson Sorensen, Kelsey Hall

Applied Sciences, Technology, and Education Student Research

Introduction and Need for Research

• A shortage of skilled college graduates
• Changes in agriculture influence an educator's ability to effectively teach agricultural topics, and variable beliefs about agriculture in the school community (i.e., students, parents, counselors) influence the number of students interested in agricultural careers
• Agricultural educators need to be trained with up-to-date information about issues and careers in agriculture
• Research Priority Area Three by preparing individuals to work in a global agriculture and natural resources workforce

Twentieth Century Geomorphic Changes Of The Lower Green River In Canyonlands National Park, Utah: An Investigation Of Timing, Magnitude And Process, Alexander E. Walker, John C. Schmidt, Paul E. Grams

Watershed Sciences Faculty Publications

Since the early 20^th century, the Green River, the longest tributary of the Colorado River, has narrowed, decreasing available riparian and aquatic habitat.

Initially, the widespread establishment of non-native tamarisk was considered to be the primary driver of channel narrowing. An alternative hypothesis postulated that changes in hydrology drove narrowing. Reductions in total streamflow and changes to flow regime occurred due to wide-spread water development, decreased snowmelt flood magnitude, and the increased cyclicity of wet and dry years. The two hypotheses agree on channel narrowing, but each influences modern river management differently. A tamarisk-driven model of narrowing implies that …

Genetic And Spatial Structuring Of Populus Tremuloides In A Mixed-Species Forest Of Southwestern Utah, Usa, Matthew Bishop, Tucker J. Furniss, Karen E. Mock, Jim A. Lutz

Wildland Resources Faculty Publications

Populus tremuloides Michx. (aspen) is an iconic species of the southwestern United States, where it is known for its extensive clonality. The size of clones and pattern of clonal distribution within and among stands can provide important clues to the species' evolution and ecology, but there are very few studies that have conducted the type of sampling necessary to define these features. We examined the genetic composition and habitat associations of aspen in a mixed-species forest in Cedar Breaks National Monument on the Markagunt Plateau, southwestern Utah. Genetic analysis of 94 stems ≥1 cm diameter at breast height (dbh) selected …
