The use and creation of undesignated recreational trails can lead to erosion, vegetation damage, unsafe trail conditions, and impacts to local wildlife. The mitigation of undesignated trail use is typically addressed indirectly through minimum-impact visitor education programs such as Leave No Trace, or directly through closures or sanctions. In this study, researchers collaborated with City of Boulder, Colorado Open Space and Mountain Parks (OSMP) staff to develop a quasi-experimental field study that examined the effectiveness of indirect (messaging) and direct (barriers) management approaches to mitigating undesignated trail use. The study applied a Theory of Planned Behavior framework, utilized Leave No Trace messaging, and employed a method to pair survey and direct observation data. A total of 2232 visitor parties were observed, and 147 surveys were collected. The combined direct (barrier) and indirect (messaging) intervention was the most effective at mitigating undesignated trail use. Implications for management and future research are discussed.

As a result of the increased interest in nontraditional activities, such as mountain biking and backpacking, many public schools are incorporating outdoor education into their curriculum. However, little attention has been given to educating students about the impacts that outdoor activities can have on the environment. It is important that schools educate students and families about environmental stewardship by incorporating Leave No Trace principles into the curriculum. This article includes teaching tips and resources that physical educators can use to implement these principles in outdoor education units to help students become well-informed citizens, as well as environmental stewards who behave ethically while engaging in physical activities in the great outdoors.

Resource degradation resulting from visitor behavior continues to be a significant concern for land managers, and effective educational messages such as those promoted through Leave No Trace, which target depreciative behaviors, are imperative. This thesis examined psychological and knowledge variables that were hypothesized to influence Leave No Trace behavioral intent of visitors to national and state parks. While knowledge, attitudes, beliefs and behaviors of outdoor enthusiasts in the context of Leave No Trace have been studied in backcountry visitors, research pertaining to frontcountry visitors is limited. Chapter 1 examined specific factors that influence Leave No Trace behavioral intent in visitors to Rocky Mountain National Park. Data were obtained from an on-site survey administered to individuals (N = 390, response rate 74%) in the Bear Lake corridor of the park. Results of a regression analysis revealed that perceived effectiveness of Leave No Trace practices is a significant predictor of future behavioral intent (β > .21, p < .001, in all cases). Frontcountry visitors like those at Bear Lake are more likely to practice Leave No Trace if they perceive the practices to be effective at reducing impacts. Chapter 2 examined variables that were hypothesized to influence Leave No Trace behavioral intent in state park visitors. Data were obtained from an on-site survey administered to individuals (N = 346, response rate 93%) in three Wyoming state parks and historic sites. Results suggest that both attitudes and the perceived effectiveness of Leave No Trace practices are meaningful predictors of behavioral intent in state park visitors, and that messaging targeting these variables can be effective at influencing behavioral intent. Both chapters in this thesis provide specific managerial implications that could strengthen Leave No Trace educational efforts in frontcountry locations by targeting specific attitudes and perceptions about recommended Leave No Trace practices in order to influence behavioral intentions. Furthermore, the results indicate that visitors to national parks and state parks could generally benefit from a more uniform approach to Leave No Trace education, which is likely to enhance overall adoption of Leave No Trace by land managers across the agency spectrum.

Dermatophytosis, also known as ringworm, is a contagious fungal skin disease affecting humans and animals worldwide. Persian cats exhibit severe forms of the disease more commonly than other breeds of cat, including other long-haired breeds. Certain types of severe dermatophytosis in humans are reportedly caused by monogenic inborn errors of immunity. The goal of this study was to identify genetic variants in Persian cats contributing to the phenotype of severe dermatophytosis. Whole-genome sequencing of case and control Persian cats followed by a genome-wide association study identified a highly divergent, disease-associated haplotype on chromosome F1 containing the S100 family of genes. S100 calcium binding protein A9 ( S100A9 ), which encodes a subunit of the antimicrobial heterodimer known as calprotectin, contained 13 nonsynonymous variants between cases and controls. Evolutionary analysis of S100A9 haplotypes comparing cases, controls, and wild felids suggested the divergent disease-associated haplotype was likely introgressed into the domestic cat lineage and maintained via balancing selection. We demonstrated marked upregulation of calprotectin expression in the feline epidermis during dermatophytosis, suggesting involvement in disease pathogenesis. Given this divergent allele has been maintained in domestic cat and wildcat populations, this haplotype may have beneficial effects against other pathogens. The pathogen specificity of this altered protein should be investigated before attempting to reduce the allele frequency in the Persian cat breed. Further work is needed to clarify if severe Persian dermatophytosis is a monogenic disease or if hidden disease-susceptibility loci remain to be discovered. Consideration should be given to engineering antimicrobial peptides such as calprotectin for topical treatment of dermatophytosis in humans and animals.

Previous research revealed the feline skin bacterial microbiota to be site-specific and the fungal microbiota to be individual-specific. The effect of other factors, such as genotype and environment, have not yet been studied in cats, but have been shown to be potentially important in shaping the cutaneous microbiota of other animals. Therefore, the objectives of this study were to evaluate the effect of these factors on the bacterial and fungal microbiota of feline skin and oral cavity. The influence of genotype was assessed through the analysis of different cat breeds, and the influence of environment through comparison of indoor and outdoor cats. DNA was extracted from skin and oral swabs, and bacterial and fungal next-generation sequencing were performed. Analysis of the skin microbiota of different cat breeds revealed significant differences in alpha diversity, with Sphynx and Bengal cats having the most diverse communities. Many taxa were found to be differentially abundant between cat breeds, including Veillonellaceae and Malassezia spp. Outdoor environment exposure had considerable influence on beta diversity, especially in the oral cavity, and resulted in numerous differentially abundant taxa. Our findings indicate that the oral bacterial microbiota and both fungal and bacterial microbiota of feline skin are influenced by breed, and to a lesser degree, environment.

The COVID-19 pandemic presents not only a global health crisis but has also disrupted the daily lives of people around the world. From a leisure perspective, urban outdoor enthusiasts are one group particularly impacted by the pandemic and the subsequent institutional response. Stay-at-home orders and physical distancing recommendations serve as potential inhibitors to outdoor recreation activities central to the lifestyles and wellbeing of outdoor enthusiasts. In urban areas, where these orders and recommendations are most restrictive, the potential impacts on recreation behavior are most consequential. This study provides an empirical analysis of the COVID-19 pandemic’s impact on the recreational behaviors of outdoor enthusiasts across urban and rural communities. Results suggest that the frequency of outdoor recreation participation, distance travelled to participate in outdoor recreation and distance travelled beyond roads during outdoor recreation have declined significantly more among outdoor enthusiasts residing in urban areas than urban clusters or rural areas.

Background Given the high risk of COVID‐19 mortality, patients with cancer may be vulnerable to fear of COVID‐19, adverse psychological outcomes, and health care delays. Methods This longitudinal study surveyed the pandemic's impact on patients with cancer (N= 1529) receiving Patient Advocate Foundation services during early and later pandemic. Generalized estimating equation with repeated measures was conducted to assess the effect of COVID‐19 on psychological distress. Logistic regression with repeated measures was used to assess the effect of COVID‐19 on any delays in accessing health care (e.g., specialty care doctors, laboratory, or diagnostic testing, etc.). Results Among 1199 respondents, 94% considered themselves high risk for COVID‐19. Respondents with more fear of COVID‐19 had a higher mean psychological distress score (10.21; 95% confidence intervals [CI] 9.38–11.03) compared to respondents with less fear (7.55; 95% CI 6.75–8.36). Additionally, 47% reported delaying care. Respondents with more fear of COVID‐19 had higher percentages of delayed care than those with less (56; 95% CI 39%–72% vs. 44%; 95% CI 28%–61%). These relationships persisted throughout the pandemic. For respondents with a COVID‐19 diagnosis in their household (n = 116), distress scores were similar despite higher delays in care (58% vs. 27%) than those without COVID‐19. Conclusions Fear of COVID‐19 is linked to psychological distress and delays in care among patients with cancer. Furthermore, those who are personally impacted see exacerbated cancer care delays. Timely psychosocial support and health care coordination are critical to meet increased care needs of patients with cancer during the COVID‐19 pandemic. Fear of COVID‐19 is associated with psychological distress and delay in cancer care. Timely psychosocial support and health care coordination are needed to meet increased care needs of patient with cancer during the pandemic.

Efforts to reintroduce species to portions of their historic ranges are growing in number and kind. These include proposals and projects to reintroduce large carnivores in areas where these species have been absent for decades. Reintroductions, like all conservation efforts, involve not only empirical and logistical problems, but also complex normative questions. So, what are the obligations, values, permissions, restrictions, and demands that citizens, conservationists, wildlife managers, and other impacted parties must address? This paper attempts to organise, summarise and briefly analyse the diverse suite of common normative arguments concerning large carnivore reintroduction. Clarifying arguments as a methodological approach grounded in environmental ethics sheds light on many implicit ethical presuppositions that underwrite reintroduction efforts. As an example, we use the grizzly bear (Ursus arctos), whose populations have grown in recent years in both Europe and North America. Whereas past efforts to recover grizzlies in the lower 48 U.S. states focused on the Northern Rockies and North Cascades, research, legal proceedings, and other proposals have emerged to return the species to other portions of its historic range, including California. Clarifying ethical arguments that may arise from large carnivore reintroduction can contribute to a more civil public discourse and effective decision-making processes.

Researchers continue to explore ways to understand and promote pro-environmental behavior (PEB) amongst various populations. Despite this shared goal, much debate exists on the operationalization and the dimensionality of PEB and how it is measured. This piecemeal approach to measurement has limited the ability to draw conclusions across studies. We address limitations associated with previous measures of PEB by developing a multi-dimensional scale that is validated across both a general population of individuals residing in the United States as well as a group of individuals associated with a pro-environmental organization. Exploratory and confirmatory factor analyses and reliability estimation were conducted for the developed measure across these two populations. Measurement invariance testing was also utilized to assess the psychometric stability of the scale across the two groups. Results indicated an 11 item scale was best fitting with two sub-scales: private and public behaviors. Implications for research and practice are discussed.

The COVID-19 pandemic has been proposed as a catalyst for many U.S. residents to re-engage in outdoor recreation or engage in outdoor recreation for the first time. This manuscript describes the results of a representative U.S. national panel study aimed at better understanding the socio-demographic profile (gender, ethnicity, community type, income, and age) of those participants new to outdoor recreation since the start of the COVID-19 pandemic. In doing so, we address how these new outdoor recreationists differ from (1) those who frequently participated in outdoor recreation prior to the pandemic and continue to participate in outdoor recreation, (2) those who did not frequently participate in outdoor recreation prior to the pandemic and remain un-engaged, and (3) those who frequently participated in outdoor recreation prior to the pandemic but stopped their frequent participation following the onset of the pandemic. Results from this U.S. national study suggest that 35.8% of respondents indicated that they did not participate regularly in outdoor recreation prior to the pandemic or during the pandemic, 30.4% indicated that they did participate regularly in outdoor recreation prior to the pandemic and continued to do so regularly during the pandemic, and 13.5% indicated that they did participate regularly in outdoor recreation prior to the pandemic, but did not continue to do so during the pandemic. More than 20% of the sample indicated that they were new outdoor recreationists. The majority of respondents in all categories, including those that were new to outdoor recreation amidst the pandemic, identified as being white, however these new outdoor recreationists were also the least ethnically diverse. The previously but no longer outdoor recreationist respondents were significantly more ethnically diverse than the other three groups, and they tended to live in more urbanized settings. Discussion of these results includes implications for outdoor recreation managers, and researchers who seek to better understand who the COVID-19 pandemic has influenced with regard to outdoor recreation participation. Implications regarding social justice, access and equity to public places that facilitate outdoor recreation, and health-related policies are discussed.
