Developing an Ecosystem Services Online Decision Support Tool to Assess the Impacts of Climate Change and Urban Growth in the Santa Cruz Watershed; Where We Live, Work, and PlayUsing respective strengths of the biological, physical, and social sciences, we are developing an online decision support tool, the Santa Cruz Watershed Ecosystem Portfolio Model (SCWEPM), to help promote the use of information relevant to water allocation and land management in a binational watershed along the U.S.-Mexico border. The SCWEPM will include an ES valuation system within a suite of linked regional driver-response models and will use a multicriteria scenario-evaluation framework that builds on GIS analysis and spatially-explicit models that characterize important ecological, economic, and societal endpoints and consequences that are sensitive to climate patterns, regional water budgets, and regional LULC change in the SCW.

Application of synthetic scenarios to address water resource concerns: A management-guided case study from the Upper Colorado River BasinWater managers are increasingly interested in better understanding and planning for projected resource impacts from climate change. In this management-guided study, we use a very large suite of synthetic climate scenarios in a statistical modeling framework to simultaneously evaluate how (1) average temperature and precipitation changes, (2) initial basin conditions, and (3) temporal characteristics of the input climate data influence water-year flow in the Upper Colorado River. The results here suggest that existing studies may underestimate the degree of uncertainty in future streamflow, particularly under moderate temperature and precipitation changes. However, we also find that the relative severity of future flow projections within a given climate scenario can be estimated with simple metrics that characterize the input climate data and basin conditions. These results suggest that simple testing, like the analyses presented in this paper, may be helpful in understanding differences between existing studies or in identifying specific conditions for physically based mechanistic modeling. Both options could reduce overall cost and improve the efficiency of conducting climate change impacts studies.

Indigenous Data Governance: Strategies from United States Native NationsData have become the new global currency, and a powerful force in making decisions and wielding power. As the world engages with open data, big data reuse, and data linkage, what do data-driven futures look like for communities plagued by data inequities? Indigenous data stakeholders and non-Indigenous allies have explored this question over the last three years in a series of meetings through the Research Data Alliance (RDA). Drawing on RDA and other gatherings, and a systematic scan of literature and practice, we consider possible answers to this question in the context of Indigenous peoples vis-á-vis two emerging concepts: Indigenous data sovereignty and Indigenous data governance. Specifically, we focus on the data challenges facing Native nations and the intersection of data, tribal sovereignty, and power. Indigenous data sovereignty is the right of each Native nation to govern the collection, ownership, and application of the tribe’s data. Native nations exercise Indigenous data sovereignty through the interrelated processes of Indigenous data governance and decolonizing data. This paper explores the implications of Indigenous data sovereignty and Indigenous data governance for Native nations and others. We argue for the repositioning of authority over Indigenous data back to Indigenous peoples. At the same time, we recognize that there are significant obstacles to rebuilding effective Indigenous data systems and the process will require resources, time, and partnerships among Native nations, other governments, and data agents.

Flexibility and partnerships perceived as supportive of dual hazard response: COVID-19 and heat related illness, Summer 2020Objectives: To understand how health departments implemented the response to the dual hazards of Heat Related Illness (HRI) and COVID-19 in Summer 2020. Methods: We interviewed five health jurisdictions with a Building Resilience Against Climate Effects (BRACE) Framework HRI project to understand impacts to organizational roles and preparedness activities, capacity to respond to the heat season, challenges experienced with resources and personnel, and how partners influenced their capacity to respond to dual hazards. Results: Health jurisdictions working in both heat preparedness and on the COVID-19 response highlighted three components as integral to maintaining public health capacity throughout the pandemic: 1) adapting to changing roles and responsibilities, 2) building and strengthening inter-organizational partnerships, and 3) maintaining flexibility through cross-training as themes to maintain the public health capacity throughout the pandemic. Conclusions: With impacts of the changing climate, including resultant extreme events with subsequent public health impacts, simultaneous responses are likely to arise again in the future. Developing cross-training programs, fostering flexibility and adaptability within the workforce, and building and sustaining external partnerships can support health departments anticipating the need to respond to simultaneous public health hazards in the future.

Leveraging university resources to build awareness, support regional food policy, and disrupt dominant narratives guiding food-based development: Examples from University of Arizona’s Center for Regional Food StudiesFood projects have become an increasingly popular engine for economic development and branding efforts to promote “creative cities” in the neoliberal context (Joassart-Marcelli & Bosco, 2017). However, proponents of food-based development often overlook the uneven impacts of such projects and neglect underlying structural, social, and environmental issues. University researchers can play a key role in raising awareness about these issues, inform food policy needs, and create university-community partnerships that can disrupt dominant narratives and support local initiatives that build capacity, equity, and resilience in regional food systems. Located in Tucson, Arizona—a UNESCO City of Gastronomy—researchers at the University of Arizona (UA)’s Center for Regional Food Studies (CRFS), in collaboration with the Climate Assessment for the Southwest (CLIMAS), endeavor to accomplish these urgent tasks through several collaborative efforts described here.

A mixed methods exploratory study assessing youth knowledge, self-efficacy and mental health outcomes in transition to adult healthcareBackground: Transition from adolescence to adulthood is a change in status yielding self-sufficiency, independence, and participation in adult roles. There are numerous efforts to define transition elements and encourage formalized processes readying youth for adulthood, yet significant challenges remain. Methods: We recruited individuals who were age 12 years or older and not transitioned or 18 years and older who transitioned within 24 months to complete questionnaires and participate in a focus group. Results: 25 participants (Mean age 17.9 years) completed questionnaires and 76 % participated in focus groups. Youth 18 years and older had mean scores in the reason for concern range on 7 of 9 NIH Toolbox scales de. Transition readiness was lower in adults across all five categories. Key themes include misunderstanding the concept of transition and self-determination in transition. Conclusions: Few youth understood what “transition” entails. Most considered it a single issue, such as aging out of insurance or leaving their pediatric specialist. Youth self-efficacy and life outlook declines in the late teens and early adulthood, exacerbating perceived inability to self-manage and gain independence. Most concerning is the emotional well-being and self-esteem of our adults who scored in the reason for concern range in 7 of 9 scales whereas adolescent peers did not. A directed attempt to create self-efficacy for youth in transition through training in health management, understanding the meaning of transition and promoting a positive perception prior to transition is needed.

Combining impact goal and impact descriptor frameworks to elucidate the societal impacts of research: a pilot studyUniversities, researchers and funders are increasingly asking how research contributes to positive changes in society and the environment, and seeking ways to document and describe impacts consistently across diverse disciplines and organisational scales. The societal impacts framework presented in this pilot study uses a combination of impact goal and impact descriptor frameworks to elucidate the societal impacts of research. The framework blends elements of assessment-driven and mission-driven reporting frameworks, and was administered online to volunteers from one interdisciplinary environmental research institute. The 12 projects in the pilot study addressed 15 of the 17 UN Sustainable Development Goals, and all 12 projects reported impacts in two or more of six impact descriptor categories. We also identified an impact subcategory dealing with changes to higher education practice. Combining two types of impacts frameworks – societal goals and descriptors of changes – allowed us to understand how the research projects contributed to broad societal goals, not just that they addressed the goals. Responses from study participants indicated a good fit between the framework and their research efforts. However, we found that the online reporting tool, in its current form, was not effective in eliciting full and accurate reports from all participants. We reflect upon how to improve data collection in the future, as well as on opportunities for additional tests of the framework in new contexts.

Household energy use response to extreme heat with a biophysical model of temperature regulation: An Arizona case studyRising temperatures associated with climate change are impacting household energy use. Many of today’s industrial-technological-urban humans thermoregulate in the face of varying temperatures using extra-metabolic energy use for heating and cooling our indoor microclimates. Previously, household energy use as a function of temperature change over seasons and time has been described using a three-part model of thermoregulation, the Extra-Metabolic Scholander-Irving model (EMSI), where energy use is lowest in the thermal neutral zone around room temperature and increases in colder and hotter temperatures. However, the EMSI model has only been evaluated for moderately warm cities to date, covering only two parts of the three-part model and lacking evaluation of data for extremely hot temperatures. We show that household energy use in Arizona, a U.S. state that includes hot semi-arid environments, varies across topography, and increases in response to the hottest summer months–exemplifying the third part of the EMSI model. Additionally, household energy use is lowest in the spring and fall and increases in response to colder temperatures in the winter. This relationship has hysteresis related to differences in household income; service regions with lower-income households delay the onset of extra-metabolic energy use for cooling. We use this model to gain predictive insights into energy use demand due to ongoing warming in the context of the desert city of Yuma, Arizona, where a relatively small increase in mean temperatures of ~1.5°C since the Industrial Revolution produced a 20-day increase (6%) in cooling days annually. Our study expands the EMSI model of thermal regulation to the previously missing hot part of the model, thereby gaining insights into the unique challenges of sustaining extra-metabolic thermoregulation in the face of global warming.

Economics, health, or environment: What motivates individual climate action?Climate change is a major threat to human health, however the role of health in climate change communication is understudied. The goal of this study was to understand how to support individuals’ adoption of climate related mitigation and adaptation activities. We hypothesized the primary motivation for engaging in pro-environmental activities would be unequally distributed across health, economics, or environment motivations. We also hypothesized respondents who felt greater susceptibility and those with higher perceived self-efficacy would adopt more pro-environmental behaviors. In 2020, we conducted a cross-sectional study using Amazon’s MTurk platform. Among the respondents, the most commonly reported activity was alternatives to private vehicles (30% already engaging), while more than two thirds of respondents reported wanting to install solar panels (70.1%) and converting to a high efficiency vehicle (63.2%). Depending on the action, respondents’ reported motivation varied. Economics was common to those who used public transportation and who installed solar paneling; purchasing a high efficiency vehicle was split between environment and economic reasons. Health was the primary motivation for converting to a plant-based diet. The perceived immediacy of climate change impacts was associated with adoption of pro-climate activities as were beliefs around human capacity to mitigate climate change. Despite the growing literature supporting health as a motivation for climate action, economic motivation was more commonly selected among the activities we evaluated. These results could aid the development of more efficient evidence-based communication strategies that would reach various audiences in society.

A new species of Nicoletiidae (Insecta: Zygentoma) from Kartchner Caverns State Park, ArizonaSpeleonycta anachoretes, n. sp., is described and differentiated from S. ozarkensis, known from caves in the Ozark Plateau. The new species was collected from Kartchner Caverns State Park in Arizona. Morphology and preliminary analyses using 16S rRNA corroborate that Speleonycta may be related to Texoreddellia, another nicoletiid genus from caves of Texas and northern Mexico. General information regarding its conservation status within the commercial cave is provided.

Biology and Ecology of Bat Cave, Grand Canyon National Park, ArizonaA study of the biology and ecology of Bat Cave, Grand Canyon National Park, was conducted during a series of four expeditions to the cave between 1994 and 2001. A total of 27 taxa, including 5 vertebrate and 22 macro-invertebrate species, were identified as elements of the ecology of the cave. Bat Cave is the type locality for Eschatomoxys pholeter Thomas and Pape (Coleoptera: Tenebrionidae) and an undescribed genus of tineid moth, both of which were discovered during this study. Bat Cave has the most species-rich macro-invertebrate ecology currently known in a cave in the park.

Description and Ecology of A New Cavernicolous, Arachnophilous Thread-legged Bug (Hemiptera: Reduviidae: Emesini) from Kartchner Caverns, Cochise County, ArizonaA new cavernicolous, arachnophilous thread-legged bug (Phasmatocoris labyrinthicussp. nov.; Reduviidae: Emesini) is described from Kartchner Caverns, a limestone cavern in Kartchner Caverns State Park near Benson, Arizona, USA. Cavernicolous emesines are recorded from caves in many parts of the world and are distributed across several genera, but are generally uncommon. P. labyrinthicus shows no obvious troglomorphy but ecological evidence suggests it is, at minimum, a cave-limited troglophile. The species seems to be low-humidity intolerant, due to its occurrence in a cave within a desert region, effectively confines the population to the cave, and the species may thus actually be troglobitic by default. Arachnophily in emesines is more common, including in Phasmatocoris Breddin, but has been previously documented in only a single cavernicolous species, Bagauda cavernicola Paiva, reported from India, Malaysia and Sri Lanka. However, unlike P. labyrinthicus, B. cavernicola is apparently not morphologically adapted for its arachnophilous association. P. labyrinthicus is the only known troglophilic emesine that is also a morphologically adapted and behaviorally functional arachnophile. The only other known cavernicolous Phasmatocoris (P. xavieri Gil-Santana, Alves, Barrett and Costa)is recorded from a sandstone cave in Brazil. P. xavieri exhibits morphological features indicative of a potentially arachnophilous habit, but its ecology has not been studied. Adults of P. labyrinthicus share characteristics with the species Phasmatocoris praecellens Bergroth, P. m i n o r McAtee and Malloch, P. xavieri, P. s p e c t r u m Breddin, and P. rapax McAtee and Malloch. Phasmatocoris is primarily a Neotropical genus and the discovery of P. labyrinthicus represents a significant range extension for the genus, being the first Nearctic species identified, with its geographically nearest relative an undescribed species from Mazatlan, Mexico, over 1,000 km to the south.

A Revision of the Genus Eschatomoxys Blaisdell (Tenebrionidae: Pimeliinae: Edrotini) with Notes on the BiologyThe tenebrionid genus Eschatomoxys Blaisdell is revised with descriptions of four new species, E. pholeter, E. paco, E. rosei, and E. andrewsi. Eschatomoxys wagneri Blaisdell, the type species, and E. tanneri Sorenson and Stones, are redescribed with illustrations and a key for the identification of all species. The biology of these rare beetles is discussed with emphasis on the cave dwelling species. The species have metapopulations fragmented among cave and island habitats.

Associations between Emesinae heteropterans and spiders in limestone caves of Minas Gerais, southeastern BrazilEmesine bugs, within several genera, are recorded from caves around the world, but have been regarded as uncommon in these habitats. Many emesines have ecological relationships with spiders, as kleptoparasites, predators, or both. However, cave emesines are apparently rarely involved in these arachnophilous relationships, and only two examples have been previously documented. Recent studies in limestone caves at Presidente Olegário in northwestern Minas Gerais, Southeastern Brazil revealed the presence of four emesine species, two of which (Emesa mourei Wygodzinsky, 1946 and Phasmatocoris sp.) were associated with spiders, probably as kleptoparasites. The spiders recorded in these associations were Mesabolivar aff. tandilicus (Mello-Leitão, 1940) (Pholcidae) and Loxosceles similis Moenkhaus, 1898 (Sicariidae). The only non-emesine reduviid recorded in Presidente Olegário caves was Zelurus zikani (Costa Lima, 1940). We discuss these rarely recorded associations between cave emesines and spiders and the importance of protecting Presidente Olegário caves.

Diversity and ecology of the macro-invertebrate fauna (Nemata and Arthropoda) of Kartchner Caverns, Cochise County, Arizona, United States of AmericaA two-year study of the diversity and ecology of the macro-invertebrate fauna (Nemata and Arthropoda) of Kartchner Caverns, near Benson, Arizona, USA, was conducted between September 2009 and September 2011. The study expands on the baseline study conducted twenty years earlier, from 1989-1991, which was one of several resource analyses conducted prior to development of Kartchner Caverns as an Arizona State Park. The recent study makes a significant contribution to the understanding of the invertebrate fauna and ecology of Kartchner Caverns and cave macro-invertebrates in the desert region of the southwestern United States and Northern Mexico. The initial study identified 39 macro-invertebrate species associated with the ecology of the cave. The recent study increased this number to 98 species, including 16 species new to science, seven of which are troglobites. Kartchner Caverns is now known to support the most species-rich macro-invertebrate ecology of any cave in Arizona.

Development and Validation of Drawing-Based Emotional Processing Scale (DRAWEP) for Art TherapistsThis study developed and evaluated the Drawing-Based Emotional Processing Scale for Art Therapists (DRAWEP) for measuring emotional processing. We collected 120 drawings from participants (aged 18–87). The study was conducted in two phases: (a) tool development through expert focus group discussions of 20 drawings, content validity and interrater reliability assessment; (b) assessment of 100 drawings for construct validity (factor structure, convergent and discriminant validity). In Phase 1 The DRAWEP tool was constructed. In Phase 2, four emotional processing factors were identified: art creation, making sense, organizing, and embodiment. Convergent and discriminant validity and reliability were satisfactory. DRAWEP may provide art therapists with a tool for evaluating latent contents of emotional processing. Further testing with clinical populations is needed.

A Theoretical Model of Emotional Processing in Visual Artmaking and Art TherapyCurrent theoretical models of emotional processing rely mainly on detecting emotional processing through verbal, conscious, and cognitive processes. However, artmaking can potentially reveal embodied and implicit processes that may otherwise remain hidden in verbal expression. This paper attempts to close the scholarly gap by introducing a novel art-based emotional processing model that integrates emotional processing and art therapy literature, incorporating emotional meaning-making, awareness, acceptance, and memory consolidation. The art-based EP model explains the processes through which art creation may benefit emotional processing. It also elucidates the ways in which art therapy can be used to enhance therapeutic outcomes.

Fair across the Board? Relating Teacher Commitment to Teachers’ Perceptions of Principal Versus Assistant Principal LeadershipPurpose: Little is known about how teachers view the leadership of assistant principals in comparison to that of principals, especially in relationship to teachers’ work outcomes. We examine whether a gap exists between teachers’ perceptions of fairness from principals and assistant principals, and whether this gap is associated with teachers’ commitment to their school. Research Methods: We employ mixed methods with a converging evidence model to understand the relationship between teachers’ perception gaps and commitment outcomes. We analyze interview data from 98 teachers across five high schools in one metropolitan area in the U.S. South to describe these gaps, and analyze survey data from 354 teachers from these same schools using structural equation modeling. Findings: Our qualitative analysis uses a typology to show examples of typical work scenarios where a teacher perceives a gap or no gap in fairness. Results from our quantitative data analysis suggest teachers express more commitment when they assess as fair (i.e., unbiased) the performance feedback from assistant principals rather than head principals. Yet, teacher commitment hinges on greater considerate interpersonal treatment from principals than from assistant principals. Overall, gaps in administrator fairness are associated with lower average teacher commitment. Implications for Research and Practice: Our investigation advances understandings of school leadership by clarifying role distinctions between principals and assistant principals that go beyond task types and considering expectations teachers hold of different school administrators. These perception differences matter as they appear associated with levels of teacher commitment.

Differences in emotional awareness moderate Cytokine-Symptom associations among breast cancer survivorsCancer survivors have elevated levels of proinflammatory cytokines, which could be associated with cancer-related symptoms. Given that proinflammatory cytokines heighten negative affect by directly affecting the brain, we explored these direct associations and whether differences in levels of emotional awareness moderate the associations between proinflammatory cytokines and cancer-related symptoms. This cross-sectional, secondary analysis of baseline data was collected from 162 female breast cancer survivors (aged 36–70 years), who were enrolled 6± 4 months after completing cancer treatment. We tested cytokines in serum (IL-1β, IL-6, IL-8, TNF-α, IL-4, IL-10, and TGF-β) and assessed depression, cancer-related fatigue, pain intensity, and pain interference. Emotional awareness was assessed using a performance measure, the Levels of Emotional Awareness Scale. In participants with high but not average or low levels of emotional awareness, positive associations were found for IL-1β, IL-6, and TNF-α with depression and between IL-6 and TNF-α with pain intensity. In addition, IL-6 had a positive association with pain intensity at average levels of emotional awareness. These results suggest that women with high or in some cases average, but not low, emotional awareness reported depression and pain as being positively associated with their cytokine levels. By using emotional awareness as a cognitive resource to promote emotion regulation and distress transformation, interventions may be able to counteract heightened sensitivity to the mood-altering effects of cytokines.
