POPULATION DYNAMICS AND HABITAT USE BY GRAY BATS IN AN ANTHROPOGENICALLY ALTERED LANDSCAPE

Habitat loss resulting from land use change is among the greatest threats to biodiversity. Yet, in some cases, imperiled wildlife species may benefit from anthropogenic disturbance. The expansion of urbanization, agriculture, renewable energy, and mining practices impact conservation efforts for threatened and endangered bat species, and particularly species that are affected by white nose syndrome (WNS). The federally endangered gray bat (Myotis grisescens) is a cavernicolous species that is susceptible to WNS. Due to their unique roosting and foraging requirements, gray bats inhabit a small portion of the accessible caves within their geographic range. As habitat loss persists, gray bats have been documented using anthropogenic structures in the absence of suitable, naturally occurring roosts. To better understand why gray bats select certain anthropogenic structures we examined the population dynamics of a gray bat colony and their use of microclimate characteristics inside a stormwater system in southeast Kansas. We described changes in temperature and relative humidity inside the roost and performed capture-mark-recapture surveys to estimate within-season population dynamics. Temperatures within the primary roost sites were on average warmer than outside temperatures, and relative humidity was We also used acoustic surveys and occupancy models to evaluate the effects of landscape composition, vegetation structure, and food availability on gray bat habitat use. The best-supported occupancy models showed a negative association with percent agriculture cover and distance from the roost site, and a positive association with canopy density, percent developed and forest cover. The stable microclimate inside the stormwater system likely provided the energetic benefits necessary for female gray bats to produce offspring. The anthropogenically altered landscape, including disturbance from surface mining, likely created the roosting and foraging habitat required for gray bats. The value of abandoned mined lands and other disturbed ecosystems should be considered when developing conservation strategies for imperiled species

Professional appraisal of online information about children’s footwear measurement and fit : readability, usability and quality

Parents increasingly use the internet to seek health information, share information and for purchasing textiles and footwear. This shift in footwear purchasing habits raises concern about how (and if) parents are getting their children's feet measured, and what support strategies are in place to support the fit of footwear. In response to this, some companies and healthcare organisations have developed resources to support home measurement of foot size, and link these measures to footwear selection, measurement and fitting. The aim of this research was to undertake an appraisal of web-based resources about measurement and fit of children's footwear, focussing specifically on readability, usability and quality. Search terms relating to children's foot measurement were compiled and online searching was undertaken. Search results were saved and screened for relevance. Existing resources were categorised based on their source e.g. a footwear company or a health website. The 15 most commonly identified resources were reviewed by a professional panel for readability, content, usability and validity. One researcher also assessed the accessibility and reading ease of the resources. Online resources were predominantly from commercial footwear companies (54%). Health information sources from professional bodies made up 4.2% of the resources identified. The top 15 resources had appropriate reading ease scores for parents (SMOG Index 4.3-8.2). Accessibility scores (the product of the number of times it appeared in search results and its ranking in the results) were highest for commercial footwear companies. The panel scores for readability ranged from 2.7 to 9 out of 10, with a similar range for content, usability and validity. Information for parents seeking to purchase footwear for their children is readily available online but this was largely dominated by commercial footwear companies. The quality and usability of this information is of a moderate standard; notable improvements could be made to the validity of the task the child is asked to undertake and the measures being taken. Improvements in these resources would improve the data input to the selection of footwear and therefore have a beneficial impact on footwear fit in children.

Searching for online information on the fit of children’s footwear during the COVID-19 pandemic: an analysis of Google Trends data

Background Selecting footwear with appropriate fit in children is challenging due the changes with foot size and dimensions which occur throughout childhood. Access to appropriate footwear is important but recent challenges with the COVID-19 pandemic resulted in closure of retail stores for prolonged periods where parents/carers could not physically purchase footwear for their children and the footwear industry suffered disruption to their supply chain, and falls in retail sales. Simultaneously increased use of social media platforms for health information seeking throughout the pandemic have been documented. This likely would have included parents/carers seeking information online to support footwear purchases for their children. The primary aim of this work was to explore how searches for online fitting information for children changed throughout the COVID-19 pandemic lockdown periods. A secondary aim was to identify how searches were influenced by footwear style. Methods We employed Google Trends to obtain search engine traffic related to footwear fitting information for children. We collected data spanning the three years pre, during and post the main national lockdown for three eight-week windows: (1) first eight weeks of the U.K. national lockdown; (2) the first eight weeks of the calendaryear; (3) the eight weeks leading up to children going back-to-school for the new academic year in the U.K. The search terms reflected parents/carers searching for footwear fit information relating to children and were grouped by style of footwear: children, infants, babies and toddlers as well as school shoes. Results We identified increased searching for footwear fit information for children during the pandemic, which reduced following post pandemic in all except the searches which related to school shoes. We saw reductions in searching related to fit of school shoes as schools closed indefinitely and an increase in online searches with the pandemic. This was also maintained post-pandemic despite shops reopening, suggesting that some of these changes in information reflect new consumer behaviours which may continue. Conclusions Increased searches for online resources regarding footwear fit highlights the importance of ensuring high quality accessible online information on footwear fit is available to support those buying footwear for their children

Association analyses of the MAS-QTL data set using grammar, principal components and Bayesian network methodologies

<p>Abstract</p> <p>Background</p> <p>It has been shown that if genetic relationships among individuals are not taken into account for genome wide association studies, this may lead to false positives. To address this problem, we used Genome-wide Rapid Association using Mixed Model and Regression and principal component stratification analyses. To account for linkage disequilibrium among the significant markers, principal components loadings obtained from top markers can be included as covariates. Estimation of Bayesian networks may also be useful to investigate linkage disequilibrium among SNPs and their relation with environmental variables.</p> <p>For the quantitative trait we first estimated residuals while taking polygenic effects into account. We then used a single SNP approach to detect the most significant SNPs based on the residuals and applied principal component regression to take linkage disequilibrium among these SNPs into account. For the categorical trait we used principal component stratification methodology to account for background effects. For correction of linkage disequilibrium we used principal component logit regression. Bayesian networks were estimated to investigate relationship among SNPs.</p> <p>Results</p> <p>Using the Genome-wide Rapid Association using Mixed Model and Regression and principal component stratification approach we detected around 100 significant SNPs for the quantitative trait (p<0.05 with 1000 permutations) and 109 significant (p<0.0006 with local FDR correction) SNPs for the categorical trait. With additional principal component regression we reduced the list to 16 and 50 SNPs for the quantitative and categorical trait, respectively.</p> <p>Conclusions</p> <p>GRAMMAR could efficiently incorporate the information regarding random genetic effects. Principal component stratification should be cautiously used with stringent multiple hypothesis testing correction to correct for ancestral stratification and association analyses for binary traits when there are systematic genetic effects such as half sib family structures. Bayesian networks are useful to investigate relationships among SNPs and environmental variables.</p

A relocatable ocean model in support of environmental emergencies

During the Costa Concordia emergency case, regional, subregional, and relocatable ocean models have been used together with the oil spill model, MEDSLIK-II, to provide ocean currents forecasts, possible oil spill scenarios, and drifters trajectories simulations. The models results together with the evaluation of their performances are presented in this paper. In particular, we focused this work on the implementation of the Interactive Relocatable Nested Ocean Model (IRENOM), based on the Harvard Ocean Prediction System (HOPS), for the Costa Concordia emergency and on its validation using drifters released in the area of the accident. It is shown that thanks to the capability of improving easily and quickly its configuration, the IRENOM results are of greater accuracy than the results achieved using regional or subregional model products. The model topography, and to the initialization procedures, and the horizontal resolution are the key model settings to be configured. Furthermore, the IRENOM currents and the MEDSLIK-II simulated trajectories showed to be sensitive to the spatial resolution of the meteorological fields used, providing higher prediction skills with higher resolution wind forcing.MEDESS4MS Project; TESSA Project; MyOcean2 Projectinfo:eu-repo/semantics/publishedVersio

Oncology EDGE Task Force on Prostate Cancer Outcomes: A Systematic Review of Outcome Measures for Functional Mobility

Background: The medical treatment of prostate cancer results in multiple impairments in body structure and declines functional abilities, resulting in activity limitations and participation restrictions. Measurement of functional mobility is an essential outcome measure in survivorship care. Purpose: The purpose of this systematic review is to make recommendations of the best measurement tools to assess functional mobility in men treated for prostate cancer based on psychometric properties and clinical utility. Methods: Multiple electronic databases were searched from February to March 2014. Studies of tools used to assess functional mobility were included if they met the following criteria: reported psychometric properties, were clinically feasible methods, and were published in the English language. Each outcome measure was reviewed independently and rated by 2 reviewers separately. A single Cancer EDGE (Evaluation Database to Guide Effectiveness) Task Force Outcome Measure Rating Form was completed for each category of functional mobility assessment, and a recommendation was made using the 4-point Cancer EDGE Task Force Rating Scale. Results: Of the original 38,373 articles found, 87 were included in this review. Conclusion: Seven tests are highly recommended by the Oncology EDGE Task Force, based on good clinical utility and psychometric properties: 2-Minute Walk Test; 6-Minute Walk Test; 10-Meter Timed Walk; the Timed-Up and Go (TUG); 5 times sit to stand; the Short Performance Physical Battery; and the Physical Performance Battery for Patients with Cancer
