The Multi-Scale Dynamics Organizing a Favorable Environment for Convective Density Currents That Redirected the Yarnell Hill Fire

The deadly shift of the Yarnell Hill, Arizona wildfire was associated with an environment exhibiting gusty wind patterns in response to organized convectively driven circulations. The observed synoptic (>2500 km) through meso-β (approximately 100 km) scale precursor environment that organized a mid-upper tropospheric cross-mountain mesoscale jet streak circulation and upslope thermally direct flow was examined. Numerical simulations and observations indicated that both circulations played a key role in focusing the upper-level divergence, ascent, downdraft potential, vertical wind shear favoring mobile convective gust fronts, and a microburst. This sequence was initiated at the synoptic scale by a cyclonic Rossby Wave Break (RWB) 72 h prior, followed by an anticyclonic RWB. These RWBs combined to produce a mid-continent baroclinic trough with two short waves ushering in cooler air with the amplifying polar jet. Cool air advection with the second trough and surface heating across the Intermountain West (IW) combined to increase the mesoscale pressure gradient, forcing a mid-upper tropospheric subsynoptic jet around the periphery of the upstream ridge over Southern Utah and Northern New Mexico. Convection was triggered by an unbalanced secondary jetlet circulation within the subsynoptic jet in association with a low-level upslope flow accompanying a mountain plains solenoidal circulation above the Mogollon Rim (MR) and downstream mountains.

Universities as Arts and Cultural Anchors

Economic developers commonly refer to universities as anchor institutions because they are large, rooted regional economic drivers that are sites of development, incubation, entrepreneurship, workforce readiness, and knowledge transfer. But most anchor research speaks generally about the university or focuses on STEM and not on arts and culture. Our study asks: what is the role of universities in anchoring arts and cultural innovation in the regional creativity ecology, and how are university leaders identifying, communicating, and investing as arts and cultural anchors? Through a qualitative comparative case analysis of four public universities in the Intermountain West combined with target interviews of field innovators and a synthesis of transdisciplinary literature, we deepen the concept of the university arts and cultural anchor and map a theoretical and practical shift from a traditional to contemporary form of anchoring. We identify four stages of anchor readiness, and we propose a pilot assessment tool for university leaders to determine their anchor stage based on awareness and investment. Our applied research helps universities move from being an arts patron to an arts entrepreneur, investor, innovator, and catalyst.

Fall Waterfowl Use of Bridgeport Reservoir, Mono County, California

Aerial surveys from 2003 to 2019 documented the abundance of waterfowl at Bridgeport Reservoir in Mono County, California, from September through mid-November. Waterfowl totals at Bridgeport Reservoir averaged 33,106 ± 4050 (standard error) in the fall. Annual peak counts averaged 10,474 ± 1349, ranging from a low of 2583 in 2014 to the highest single-day count of 23,150 in 2005. Bridgeport Reservoir is a man-made water body in the intermountain West that waterfowl use primarily a mid-migration stopover site, with peak numbers occurring in September. The dominant waterfowl species, the Northern Shoveler (Spatula clypeata), Gadwall (Mareca strepera), Mallard (Anas platyrhynchos), Northern Pintail (A. acuta), and Green-winged Teal (A. crecca), showed both unimodal and bimodal migration chronologies. Regional drought, as indicated by the Palmer drought severity index, combined with a downward trend in waterfowl numbers explained 61.4% of annual variation in fall waterfowl totals. These data may allow future assessment of change in waterfowl abundance at Bridgeport Reservoir in the context of local or regional conditions, and as influenced by climate change.

50 Using GPS and Genomic Technology to Provide a More Accurate Estimate of Bull Power in Western Intermountain Beef Systems

The objective of this study was to utilize GPS technology and genomic parentage testing to provide a more accurate measurement of bull power in the intermountain west beef production system. Breeding seasons are typically conducted on large, remote pastures, leading to current estimates of bull:cow ratios (1:20 or 1:25) possibly being inaccurate. With advances in genetic testing, parentage of calves can be obtained allowing producers to review which calves were sired from specific bulls, or how many cows each bull serviced (bull power). Our study fit 5 bulls from the same herd with GPS collars and collected hair samples for future DNA extraction prior to the 2018 breeding season. Bull movement was tracked over a 90-day breeding season on a large grazing allotment on the southern Utah and northern Arizona border. The GPS collars collected measurements of total distance traveled per day and distance traveled away from water, along with geocoordinates. Upon completion of the breeding season, collars were removed and data retrieved. At calving, biological material was collected and parentage testing of 104 calves was conducted and parentage determined. Results of parentage testing revealed that actually 6 bulls sired calves during the 2018 breeding season. The ranch’s bulls sired 72 (69%) calves (30, 16, 14, 10 and 2 calves, respectively). Thirty-two (31%) calves were sired by bulls from herds that grazed nearby. Interesting to note is the producer was unaware of any non-herd bulls co-mingling with this herd. While results from the current study are very preliminary, they do validate the importance of verifying bull power and sire identification to critically evaluate sire performance and increase the accuracy of selection in breeding replacements. The information presented herein may prove useful as a future selection tool to identify bulls that are high performing during breeding season in the intermountain west.

Queer Lives in Idaho and the Surrounding Region

The experiences of Queer people in the Intermountain-West are under- documented by the scientific community. Suicide is the 10th leading cause of death in the United States. It was responsible for more than 47,500 deaths in 2019. Members of the Queer community have higher rates of suicidal ideation and attempts than the general population. Theoretically, we may predict that people experience negative mental health outcomes under situations of reduced social contact and support or during periods of exclusion by conspecifics. My research explores mental health in the Queer community utilizing data collected in an online survey during the COVID-19 pandemic. With a sample size of 147 participants from the intermountain west, this study examines whether rates of suicidal ideation and behavior are influenced by a person’s high school experience. Specifically, I investigate effects of experienced positive curriculum related to Queer identities, supportive teachers, status of protection under the law, and the impact of COVID-19, particularly related to a lack of pride festivals. Statistical analysis found that mental health declined during the pandemic, and when sexual and gender identity are included in anti-discrimination laws Queer people’s mental health improves. These findings are supported in the high school environment as well. People who heard anti- Queer had five times the odds of engaging in suicidal behaviors. Access to a supportive community improves mental health and suggests that the adaptive use of technology to create social connections in novel ways may be key to thriving during times of cultural change and unpredictability.
