Permafrost degradation is delivering bioavailable dissolved organic matter (DOM) and inorganic nutrients to surface water networks. While these permafrost subsidies represent a small portion of total fluvial DOM and nutrient fluxes, they could influence food webs and net ecosystem carbon balance via priming or nutrient effects that destabilize background DOM. We investigated how addition of biolabile carbon (acetate) and inorganic nutrients (nitrogen and phosphorus) affected DOM decomposition with 28-day incubations. We incubated late-summer stream water from 23 locations nested in seven northern or high-altitude regions in Asia, Europe, and North America. DOM loss ranged from 3% to 52%, showing a …

Research And Publishing During Covid-19, Avery C. Edenfield, Annie Isabel Fukushima, Becky L. Thoms, Elizabeth Vargis, Christy M. Glass

Intersections on Inclusion: Critical Conversations about the Academy

This discussion will explore the impact of the COVID-19 pandemic on scholarly research and publishing. Travel restrictions, retracted funding, delayed or halted projects, and an increase in caretaker and other personal responsibilities at home compound to create unprecedented challenges for producing and publishing research. Early indicators show women, those with significant unpaid care responsibilities, and members of minoritized groups have been disproportionately impacted. For graduate students and early career faculty who depend on research and publication for promotion and tenure, the stakes are especially high. Join our panelists for a conversation about the how the COVID-19 pandemic is impacting the …

Genetic Variation At The Species And Population Levels In The Rocky Mountain Ridged Mussel (Gonidea Angulata) – Supplementary Material, James A. Walton, Karen E. Mock, Steven F. R. Brownlee, Jon H. Mageroy, Greg Wilson, Ian R. Walker

Browse all Datasets

Freshwater mussels in western North America are threatened by water diversions, climate change, loss of required host fish, and other factors, and have experienced marked decline in the past several decades. All four of the primary lineages (potentially species) of freshwater mussels in the western U.S. and Canada are widespread and have somewhat generalist host fish requirements. Of these lineages, perhaps the most poorly understood and of greatest conservation concern is Gonidea angulata (Rocky Mountain ridged mussel). Gonidea is a monotypic genus occurring only in the western continental U.S. and southern Canada. Here we describe the patterns of genetic variation …

Increasing Our Ability To Predict Contemporary Evolution, Patrik Nosil, Samuel M. Flaxman, Jeffrey L. Feder, Zachariah Gompert

Biology Faculty Publications

Classic debates concerning the extent to which scientists can predict evolution have gained new urgency as environmental changes force species to adapt or risk extinction. We highlight how our ability to predict evolution can be constrained by data limitations that cause poor understanding of deterministic natural selection. We then emphasize how such data limits can be reduced with feasible empirical effort involving a combination of approaches.

Evolution Of A Multi-Layered World Of Science To Benefit Children With Hearing Loss, Ellen Rhoades, Rachel Glade

Journal of Early Hearing Detection and Intervention

This is a brief but broad narrative and non-systematic review of developments that led up to how 21^st century digital technology and translational research influenced, in particular, cognitive psychology and our improved understanding of mental resources among children with hearing loss. In turn, systemic multi-disciplinary research findings gave birth to Auditory Cognitive Neuroscience (ACN). Three broad constructs unique to ACN, i.e., auditory attention, effortful listening, and auditory fatigue, are then described in relation to children with hearing loss. This review concludes with a brief examination of future opportunities for researchers and clinicians who can ensure that children with hearing …

Eutrophication is a widespread environmental change that usually reduces the stabilizing effect of plant diversity on productivity in local communities. Whether this effect is scale dependent remains to be elucidated. Here, we determine the relationship between plant diversity and temporal stability of productivity for 243 plant communities from 42 grasslands across the globe and quantify the effect of chronic fertilization on these relationships. Unfertilized local communities with more plant species exhibit greater asynchronous dynamics among species in response to natural environmental fluctuations, resulting in greater local stability (alpha stability). Moreover, neighborhood communities that have greater spatial variation in plant species …

On Correctness, Precision, And Performance In Quantitative Verification: Qcomp 2020 Competition Report, Carlos E. Budde, Arnd Hartmanns, Michaela Klauck, Jan Křetínský, David Parker, Tim Quatmann, Andrea Turrini, Zhen Zhang

Electrical and Computer Engineering Faculty Publications

Quantitative verification tools compute probabilities, expected rewards, or steady-state values for formal models of stochastic and timed systems. Exact results often cannot be obtained efficiently, so most tools use floating-point arithmetic in iterative algorithms that approximate the quantity of interest. Correctness is thus defined by the desired precision and determines performance. In this paper, we report on the experimental evaluation of these trade-offs performed in QComp 2020: the second friendly competition of tools for the analysis of quantitative formal models. We survey the precision guarantees - ranging from exact rational results to statistical confidence statements - offered by the nine …

Effect Of Three Classroom Research Experiences On Science Attitudes, Lauren K. Lucas, Frances K. Hunter, Zachariah Gompert

Journal on Empowering Teaching Excellence

Here we evaluate undergraduate student attitudes about science after each of three authentic research experiences in a semester of an introductory biology laboratory course at Utah State University. The three course-based research experiences (CUREs) vary in length and student freedom, and they cover different areas of biology. Students responded to the science attitude items of the CURE Survey. When compared to national data, our students faired similarly, and all students struggled with certain epistemic assumptions about science knowledge. As also seen in the national database, change in science attitude was slight and nonlinear. Student self confidence in what a career …

Journal on Empowering Teaching Excellence

Whether it be videotaping, guided classroom conversations, lecture-based, or written, feedback is the backbone of educational excellence. We use it to mentor beginning undergraduates, writers, readers, explorers, and experimenters. And, if we are thoughtful, feedback becomes a loop by which we slow down learning, we engage reading, writing and exploring, and we collaborate our way to becoming better.

Trophic Structure Of Apex Fish Communities In Closed Versus Leaky Lakes Of Arctic Alaska, Stephen L. Klobucar, Phaedra Budy

Watershed Sciences Faculty Publications

Despite low species diversity and primary production, trophic structure (e.g., top predator species, predator size) is surprisingly variable among Arctic lakes. We investigated trophic structure in lakes of arctic Alaska containing arctic char Salvelinus alpinus using stomach contents and stable isotope ratios in two geographically-close but hydrologically-distinct lake clusters to investigate how these fish may interact and compete for limited food resources. Aside from different lake connectivity patterns (‘leaky’ versus ‘closed’), differing fish communities (up to five versus only two species) between lake clusters allowed us to test trophic hypotheses including: (1) arctic char are more piscivorous, and thereby grow …

Spatial And Temporal Dynamics Of Human–Wildlife Conflicts In The Kenya Greater Tsavo Ecosystem, Joseph M. Mukeka, Joseph O. Ogutu, Erustus Kanga, Eivin Røskaft

Human–Wildlife Interactions

Biodiversity conservation in developing countries is faced with many and mounting challenges, including increasing human–wildlife conflicts (HWCs). In Africa and other developing countries, increasing HWCs, particularly those adjacent to protected areas, can adversely affect local stakeholder perceptions and support for conservation. We analyzed HWC reports for multiple wildlife species compiled >23 years (1995–2017) from the Greater Tsavo Ecosystem (GTE) in Kenya to determine HWC trends. The GTE is the largest protected area in Kenya, covering 22,681 km². Overall, 39,022 HWC incidents were reported in 6 GTE regions (i.e., Taveta, Mutomo, Kibwezi, Rombo, Galana, Bachuma). The 5 wildlife species …

The National Wild Pig Task Force leadership and conference organizers took immediate action to cancel the conference and then later announced they would host the first totally virtual wildlife management conference. This Back Page article describes the shift to a fully virtual conference.

Intake Of Supplemental Deer Pellets Containing Ground Blueberry Juniper By Wild Pigs, Jessica L. Glasscock, Travis R. Whitney, David G. Hewitt, Susan M. Cooper, Fred C. Bryant, Christina M. Toenjes

Human–Wildlife Interactions

Supplemental feeding of cervid species such as white-tailed deer (Odocoileus virginianus; deer) is now a common management practice in the United States. Supplemental feeding can be costly and more expensive when supplements are consumed by non-target species such as wild pigs (Sus scrofa; pigs). From May 13 to June 17, 2015, we evaluated the effects of using ground blueberry juniper (Juniperus ashei) or cottonseed (Gossypium spp.) hulls as a roughage ingredient in a supplemental deer pellet to deter pig consumption at the Texas A&M AgriLife Research Center in San Angelo, Texas, USA. We analyzed …

Indigenous Guardianship And Moose Monitoring: Weaving Indigenous And Western Ways Of Knowing, Jesse N. Popp, Pauline Priadka, Megan Young, Kevin Koch, James Morgan

Human–Wildlife Interactions

Increasing global rates of wildlife species extinctions, extirpations, and declines warrant improvements to population monitoring and management approaches. To address regional environmental and wildlife issues, Indigenous communities globally are re-establishing traditional roles as stewards of the land through emerging Indigenous Guardianship Programs (IGPs). By providing the opportunity for community-level participation in monitoring and management, IGPs help foster cohesive solutions for long-term conservation of species while promoting environmental stewardship at the community level. Addressing challenges in monitoring and management of wildlife is especially critical for species that are of cultural and ecological importance at both community and distribution-wide scales. Herein, we …

Advancing Best Practices For Aversion Conditioning (Humane Hazing) To Mitigate Human–Coyote Conflicts In Urban Areas, Lesley Sampson, Lauren Van Patter

Human–Wildlife Interactions

Coyotes (Canis latrans) are now recognized as a permanent feature in urban environments across much of North America. Behavioral aversion conditioning, or humane hazing, is increasingly advocated as an effective and compassionate alternative to wildlife management strategies, such as trap and removal. Given a growing public interest in humane hazing, there is a need to synthesize the science regarding methods, outcomes, efficacy, and other relevant considerations to better manage human–coyote conflicts in urban areas. This paper was prepared as an outcome of a workshop held in July 2019 by Coyote Watch Canada (CWC) to synthesize the literature on …

Caring For The Circle Of Life: Wildlife Rehabilitation And Sanctuary Care, Donna J. Perry, Jacob P. Averka

Human–Wildlife Interactions

In the United States alone, there are >5,000 state-licensed wildlife rehabilitators in addition to a multitude of other wildlife caregivers across rehabilitation and sanctuary settings. Wildlife rehabilitation and sanctuary care provide a unique lens from which to explore human–wildlife interactions. We examined the experiences of wildlife caregivers within a continuum of acute veterinary services, community-based rehabilitation, and sanctuary care to gain insight into wildlife caregiving and its implications for human–wildlife coexistence. Between 2016 and 2018, we completed in-depth interviews with 15 wildlife caretakers in Massachusetts, Maine, and New Hampshire, USA. In addition to the interviews, we observed 197 unique human–animal …
