Herbicide Control of Broom Snakeweed (Gutierrezia sarothrae)

Clinton A. Stonecipher, Corey Ransom, Eric Thacker & Kevin D. Welch
Broom snakeweed (Gutierrezia sarothrae [Pursh] Britton & Rusby) is a native invasive species that is widely distributed across western North America. It is very competitive with other vegetation and can reduce or displace desirable grasses and forbs. Removal of snakeweed from rangelands can result in increased forage production of desirable plant species. The evaluation of new herbicides to determine their efficacy in controlling broom snakeweed assists in providing land managers with alternatives to control broom...

Dataset for \"Attributes of Phragmites australis in response to climate change using a common garden study\"

Steve Young
The response of plant species to environmental change, including climate, is based on phenotypic plasticity. Empirical research can help in understanding how invasive plants adapt to changing conditions for successful establishment. Our goal was to assess the effect of environment of origin and ecotypic variation on phenotypic response of native and invasive Phragmites australis using morphological and ecophysiological measurements. We established a common garden study using seeds collected from Southwest, Midwest, and Great Lakes regions...

Biogeographic parallels in thermal tolerance and gene expression variation under temperature stress in a widespread bumble bee

Meaghan Pimsler, Kennan Oyen, James Herndon, Jason Jackson, James Strange, Michael Dillon & Jeff Lozier
Global temperature changes have emphasized the need to understand how species adapt to thermal stress across their ranges. Genetic mechanisms may contribute to variation in thermal tolerance, providing evidence for how organisms adapt to local environments. We determine physiological thermal limits and characterize genome-wide transcriptional changes at these limits in bumble bees using laboratory-reared Bombus vosnesenskii workers. We analyze bees reared from latitudinal (35.7–45.7°N) and altitudinal (7–2154 m) extremes of the species’ range to correlate...

Visual-Based Social Norms, Distance-Related Human–Wildlife Interactions, and Viewing Devices in Parks and Protected Areas

Stephanie Freeman, Zachary D. Miller & B. Derrick Taff
Distance-related human–wildlife conflict presents a serious challenge in parks and protected areas across the world. Finding ways to alleviate distance-related human–wildlife conflict is hampered by both the difficulty of studying human–wildlife interactions in the field as well as the dearth of existing methodological tools. The purpose of this study is to investigate factors of group size, distance from bison (Bison bison), and use of wildlife viewing equipment on visitor proximity preferences in Yellowstone National Park...

Self-Evaluation Report for Society of American Foresters' Continued Accreditation of Bachelor of Science Degree in Forest Ecology and Management

Karen E. Mock &
This self-evaluation report has been produced for the purpose of reaccreditation of the Utah State University Forest Ecology and Management (FEMA) undergraduate degree program by the Society of American Foresters (SAF). Utah State University has maintained an SAF-accredited forestry program since 1936 and was most recently reaccredited by SAF in 2010. Utah State University has a long and influential legacy in the forestry profession. Our faculty have led and shaped the profession, and our graduates...

Residential Preferences Study

Arthur Kaplan & Kristopher Toff
This study reports on estimates of residential preferences in the Mountain West region of the US. The estimates are derived from a choice experiment funded by the Utah Department of Transportation and Utah Transit Authority – an experiment based on large samples of both homeowners and renters who participated in a larger, statewide transportation study. The choice experiment and transportation study provides a rich set of household- and individual-specific demographic controls, enabling us to identify...

Artificial nightlight alters the predator-prey dynamics of an apex carnivore

Mark Ditmer, David Stoner, Clinton D. Francis, Jesse Barber, James Forester, David Choate, Kirsten Ironside, Kathleen Longshore, Kent Hersey, Randy Larsen, Brock McMillan, Daniel Olson, Alyson Andreasen, Jon Beckmann, Brandon Holton, Terry Messmer & Neil Carter
Artificial nightlight is increasingly recognized as an important environmental disturbance that influences the habitats and fitness of numerous species. However, its effects on wide-ranging vertebrates and their interactions remain unclear. Light pollution has the potential to amplify land-use change, and as such, answering the question of how this sensory stimulant affects behavior and habitat use of species valued for their ecological roles and economic impacts is critical for conservation and land-use planning. Here, we combined...

Investigating the morphological and genetic divergence of arctic char (Salvelinus alpinus) populations in lakes of arctic Alaska

Stephen L. Klobucar, Jessica Rick, Elizabeth Mandeville, Catherine Wagner & Phaedra Budy
Polymorphism facilitates coexistence of divergent morphs (e.g., phenotypes) of the same species by minimizing intraspecific competition, especially when resources are limiting. Arctic char (Salvelinus sp.) are a Holarctic fish often forming morphologically, and sometimes genetically, divergent morphs. In this study, we assessed the morphological and genetic diversity and divergence of 263 individuals from seven populations of arctic char with varying length-frequency distributions across two distinct groups of lakes in northern Alaska. Despite close geographic proximity,...

The Comparative Cytotoxicity of Riddelliine in Primary Mouse, Rat and Chick Hepatocytes

Bryan L. Stegelmeier, William S. Resager & Steven M. Colegate
Dehydropyrrolizidine alkaloid (DHPA) producing plants commonly poison livestock, wildlife and humans. Poisoning occurs when DHPAs are ingested as feed or food, or when they contaminate medicinal or herbal products. Direct toxicologic comparison of individual DHPAs is essential to estimate their actual health risks. This has been problematic due to varying models and difficulties in DHPA isolation or synthesis. In contrast, the macrocyclic DHPA riddelliine is readily isolated and it has been used as a benchmark...
