Improving Conservation and Recreation in Environments Shared by Humans and Bats

White-nose syndrome (WNS) has drastically changed how caves are managed in the United States. This disease has killed millions of bats throughout eastern North America and continues to spread westward. Since the discovery of WNS, The U.S. National Park Service (NPS) has acted to slow the spread of the disease through the development of educational programs and the deployment of decontamination measures. Despite the vast array of research on the biological and ecological aspects of bats and WNS, few studies focus on how visitor attitudes and knowledge of management strategies implemented in response to WNS impact the effectiveness of these programs. To better inform management decisions, I examined national park visitor attitudes towards bats and common cave management actions. To better understand the context surrounding WNS management in U.S. national parks, I conducted in-depth qualitative interviews with 15 key informants that worked for or closely with the National Park Service. Common themes emerged from these interviews, including the diversity of cave management programs in national parks, the use of context-specific management plans, the similar challenges national parks face when managing for bats and WNS, and the difference in cave management perceptions between the general public and cavers. Using this information, I created a visitor survey assessing their attitudes towards bats, knowledge of WNS, and perceptions of common WNS preventive measures. I surveyed 1365 visitors at eight national parks throughout the country during the summer of 2019. Overall, respondents expressed positive attitudes towards bats, moderate to high knowledge of bat ecology, and a high recognition of WNS. Visitor recognition of WNS varied greatly between the parks, with visitors at Jewel Cave National Monument (South Dakota) having the highest recognition of WNS (87%) and visitors at El Malpais National Monument (New Mexico) having the lowest recognition of WNS (63%). Using the Theory of Planned Behavior as a framework, we also found that visitors would likely follow WNS preventive actions, with structural equation models showing that attitudes and subjective norms had the greatest influence over visitor behavioral intent. Using these results, I present the implications of this research and management actions that may be implemented to meet multiple conservation objectives. It will be crucial to continue to integrate biological and social science research to achieve management goals focused on enhancing recreation and conservation in environments shared by humans and bats

Tropical Trees as Islands: Diversity Accumulation of Armored Scale Insects (Hemiptera: Diaspididae) on Trees as a Function of Forest Age

Armored scale insects (Hemiptera: Diaspididae) are some of the most invasive insects in the world. These cryptic plant parasites are most often encountered in managed agricultural ecosystems, but very little is known about their distribution, abundance, and diversity in tropical rainforest canopies, where they are likely to have their highest diversity. Because these ubiquitous insects are extreme generalists with undirected dispersal, their diversity (alpha and beta) accumulation can conceivably be modeled according to tenets derived from island biogeography theory. For example, one expectation is that older established trees should boast a higher species diversity and abundance than younger ones. Other aspects of island biogeography theory have been unexplored, especially in regards to expected phylogenetic patterns of community structure. In this study we combine an intense ecological survey with a community phylogenetics approach to examine these unexplored aspects. Specimens were collected in an intensive survey from both (1) a tropical rainforest canopy using a canopy access crane in the Daintree Rainforest in Australia; and (2) an adjacent five year-old reforestation plot that had a similar diversity and constituency as the mature plot. We use a combination of systematic environmental sampling and molecular and morphological species delimitation techniques to compare and contrast the abundance, diversity, and community phylogenetics of these two habitats in order to address this question

Hard Choices: Navigating the Economic Shock of Unemployment

During the Great Recession of 2007 to 2009, millions of Americans faced severe economic hardship, forcing difficult decisions about how to stabilize their families' financial well-being and prevent downward economic mobility. Americans with savings were forced to weigh immediate needs against long-term investments, choosing whether to deplete personal assets in order to stay afloat. Those without wealth to fall back on were in an even more precarious position, leading them to turn to family assistance, debt, and other public and private supports when available.This study examines how families weather economic shocks through a close focus on one particular event -- the experience of unemployment, with specific attention to differences by race and family income. The analysis used a nationally representative sample of working-age families from the Panel Study of Income Dynamics or PSID, following the same households from 1999 to 2009. To provide greater insight into the challenges and choices families faced, the report also drew on a unique longitudinal data set of in-depth interviews with 51 families that endured one month or more of unemployment between 1998 and 2012

Can Farmers and Bats Co-exist? Farmer Attitudes, Knowledge, and Experiences with Bats in Belize

Bats (Chiroptera) are often viewed negatively by the public. Negative public perceptions of bats may hinder efforts to conserve declining populations. In Belize, the presence of vampire bats (Desmodus rotundus and Diphylla ecaudata) exacerbates the potential for conflicts with humans because of the increased rabies transmission risks. To mitigate these risks, the Belize government provides farmers with assistance to trap and remove vampire bats. In June 2018, we surveyed farmers (n = 44) in and adjacent to the Vaca Forest Reserve in Belize to learn more about their attitudes, knowledge, and experiences with bats. This information may provide new insights and approaches to address farmers’ concerns and enhance bat conservation efforts in Belize. Farmers held negative attitudes toward bats, exhibited low knowledge of their ecosystem services, and supported the trapping and use of toxicants to control bat populations to reduce the risk of rabies transmission between vampire bats and livestock. Farmers with livestock had more negative attitudes toward bats than farmers without livestock. Despite farmers reporting depredation incidences with fruit-eating and vampire bats, farmers expressed more negative attitudes toward vampire bats. We recommend that conservation education efforts target all stakeholders in the reserve to increase awareness about the importance of bats to ecosystems and highlight the dangers of indiscriminate trapping. Cumulatively, this may lead to positive attitude changes toward bats and their conservation

Early changes in brain structure correlate with language outcomes in children with neonatal encephalopathy.

Global patterns of brain injury correlate with motor, cognitive, and language outcomes in survivors of neonatal encephalopathy (NE). However, it is still unclear whether local changes in brain structure predict specific deficits. We therefore examined whether differences in brain structure at 6 months of age are associated with neurodevelopmental outcomes in this population. We enrolled 32 children with NE, performed structural brain MR imaging at 6 months, and assessed neurodevelopmental outcomes at 30 months. All subjects underwent T1-weighted imaging at 3 T using a 3D IR-SPGR sequence. Images were normalized in intensity and nonlinearly registered to a template constructed specifically for this population, creating a deformation field map. We then used deformation based morphometry (DBM) to correlate variation in the local volume of gray and white matter with composite scores on the Bayley Scales of Infant and Toddler Development (Bayley-III) at 30 months. Our general linear model included gestational age, sex, birth weight, and treatment with hypothermia as covariates. Regional brain volume was significantly associated with language scores, particularly in perisylvian cortical regions including the left supramarginal gyrus, posterior superior and middle temporal gyri, and right insula, as well as inferior frontoparietal subcortical white matter. We did not find significant correlations between regional brain volume and motor or cognitive scale scores. We conclude that, in children with a history of NE, local changes in the volume of perisylvian gray and white matter at 6 months are correlated with language outcome at 30 months. Quantitative measures of brain volume on early MRI may help identify infants at risk for poor language outcomes

A randomised pilot feasibility study of eye movement desensitisation and reprocessing recent traumatic episode protocol, to improve psychological recovery following intensive care admission for COVID-19

© 2022 The Intensive Care Society. This is the accepted manuscript version of an article which has been published in final form at https://doi.org/10.1177/17511437221136828Background: Approximately 50% of intensive care survivors experience persistent psychological symptoms. Eye-movement desensitisation and reprocessing (EMDR) is a widely recommended trauma-focussed psychological therapy, which has not been investigated systematically in a cohort of intensive care survivors: We therefore conducted a randomised pilot feasibility study of EMDR, using the Recent Traumatic Episode Protocol (R-TEP), to prevent psychological distress in intensive care survivors. Findings will determine whether it would be possible to conduct a fully-powered clinical effectiveness trial and inform trial design. Method: We aimed to recruit 26 patients who had been admitted to intensive care for over 24 h with COVID-19 infection. Consenting participants were randomised (1:1) to receive either usual care plus remotely delivered EMDR R-TEP or usual care alone (controls). The primary outcome was feasibility. We also report factors related to safety and symptom changes in post-traumatic stress disorder, (PTSD) anxiety and depression. Results: We approached 51 eligible patients, with 26 (51%) providing consent. Intervention adherence (sessions offered/sessions completed) was 83%, and 23/26 participants completed all study procedures. There were no attributable adverse events. Between baseline and 6-month follow-up, mean change in PTSD score was −8 (SD = 10.5) in the intervention group versus +0.75 (SD = 15.2) in controls (p = 0.126). There were no significant changes to anxiety or depression. Conclusion: Remotely delivered EMDR R-TEP met pre-determined feasibility and safety objectives. Whilst we achieved group separation in PTSD symptom change, we have identified a number of protocol refinements that would improve the design of a fully powered, multi-centre randomised controlled trial, consistent with currently recommended rehabilitation clinical pathways.

Enhancing comfort of resident physicians treating adults with intellectual and developmental disabilities by facilitating meaningful interactions

BackgroundMany physicians feel uncomfortable caring for patients with intellectual and developmental disabilities (IDD). While some residency training programs include lecture content on IDD, few provide structured experiences with individuals with IDD. One strategy for improving comfort is “contact theory:” increasing interactions with “dissimilar” people can lead to decreased negative attitudes toward that population.ObjectiveEvaluate the impact of an interactive session on resident physicians’ comfort with adults with IDD.MethodsSmall groups of resident physicians and artists with IDD collaborated on art projects during the noon conference. A prospective pre-post-intervention survey, including the validated Interaction with Disabled Persons Scale (IDP), evaluated residents’ comfort with patients with IDD before and after the session.Results53 residents completed both pre- and post-conference surveys. Mean IDP scores decreased from 78.7 (10.9) to 75.8 (9.5; p < 0.01), indicating decreasing discomfort. The mean level of comfort interacting with individuals with IDD increased from uncomfortable 3.6 (1.2), before the intervention, to comfortable 4.4 (1.2) after the intervention (p = <0.01). The mean level of comfort treating individuals with IDD increased from uncomfortable 3.5 (1.1) to comfortable 4.1 (1.3) after the intervention (p < 0.01).DiscussionProviding resident physicians with real-life connections with people with IDD was associated with increased comfort. If statistically significant improvements occurred after one session, future studies should evaluate if additional experiences with people with IDD could have more substantial, lasting impacts on future doctors’ comfort with and willingness to care for patients with IDD

Engaging stakeholders in wildlife disease management: Hunters' willingness to adopt and support biosecurity actions to prevent the spread of rabbit hemorrhagic disease

Rabbit hemorrhagic disease virus 2 (RHDV2) is a highly contagious virus that primarily infects rabbits and hares (lagomorphs) and poses a serious threat to lagomorph populations and hunting. Wildlife agencies in the United States rely on hunters to report RHDV2-related mortalities and engage in voluntary biosecurity actions to prevent the spread of RHDV2. From April 2021 to April 2022, we conducted a nationwide survey of 22,511 hunters to ascertain their willingness to engage in voluntary biosecurity actions and support government-mandated biosecurity measures. Respondents expressed greatest willingness to report suspicious lagomorph deaths to wildlife agencies. Respondents' willingness to engage in or support biosecurity actions was positively correlated with their risk perceptions pertaining to lagomorph deaths and the economic impacts of RHDV2, perceptions of the importance of biosecurity, and trust in state agencies to manage RHDV2. We found evidence that respondents' willingness to engage in or support biosecurity actions was also positively correlated with their knowledge of RHDV2. Wildlife agencies should clearly communicate about RHDV2 and its adverse impacts on lagomorphs, biodiversity, and hunting to engage hunters in biosecurity measures. Hunters can provide valuable information about lagomorph population trends and mortality events in the areas they hunt, a cost-effective method to augment agency surveillance.DATA AVAILABILITY STATEMENT : Deidentified data that support the findings of this study are available at Hannah G.
