The southeastern United States experiences some of the greatest tornado fatality rates in the world, with a peak in the western portion of the state of Tennessee. Understanding the physical and social characteristics of the area that may lead to increased fatalities is a critical research need. Residents of 12 Tennessee counties from three regions of the state (N = 1804) were asked questions about their perception of climatological tornado risk in their county. Approximately half of participants underestimated their local tornado risk calculated from 50 years of historical tornado data...

Recent findings highlight the role of skin microbiome in modulating immune function and inflammatory response. This systematic review aims to investigate the effects of muds, already used for the treatment of several rheumatic and dermatologic conditions, on skin microbiome. Medline via PubMed, Embase, Cochrane Library, and Google Scholar were searched for articles about the effects of therapeutic muds on microorganisms of skin microbiome. Five studies were included in the review and critically appraised. Limited data suggest that muds have various properties that may explain their action on skin microbiome, with different effects on commensal and pathogenic microorganisms...

In this study, we addressed potential biases which can occur when sensorial scores of temperature, wetness and discomfort are repeatedly reported, in transient exercise conditions. We pointed out that, when repeatedly reported, previous sensorial scores can be set by the participants as reference values and the subsequent score may be given based on the previous point of reference, the latter phenomenon leading to a bias which we defined as 'anchoring bias'. Indeed, the findings shown that subsequent sensorial scores are prone to anchoring biases and that the bias consisted in a systematically higher magnitude of sensation as compared to when reported a single time only...

This study examines the extent to which people with different past thermal experience and "climatocultural" history systematically report different outdoor thermal sensations and thermal comfort patterns. After constructing two distinct climatocultural groups co-inhabiting the research setting (native Israelis vs. representatives of colder regions), and comparing their relative thermal preferences in both short-term and long-term observational experiments, we confirmed the existence of a strong correlation between affiliation to a certain climatocultural group and outdoor thermal sensation...

Contact skin temperature (Tsk ) sensors are calibrated under uniform thermal conditions but used in the presence of a skin-to-environment temperature gradient. We aimed to characterise the validity of contact Tsk sensors when measuring surface temperature under a range of environmental and fabric coverage conditions, to estimate practical temperature limits for a given measurement bias and to explore correcting for bias. Using two types of contact Tsk sensors (thermistors, n = 5; iButtons, n = 5), we performed experiments in three phases: (1) conventional calibration (uniform thermal environment) over 15-40 °C in 5 °C steps (at t = 0, and 24 h, 12 weeks later), (2) surface temperature measurements of a purpose-made aluminium plate (also 15-40 °C) at different environmental temperatures (15, 25, 35 °C) with different sensor attachments and fabric coverings to assess measurement bias and calculate correction factors that account for the next-to-surface microclimate temperature and (3) surface measurements (33...

Brazil is the major coffee producer in the world, with 2 million hectares cropped, with 75% of this area with Coffea arabica and 25% with Coffea canephora. Coffee leaf rust (CLR) is one of the main diseases that cause yield losses by reducing healthy leaf area. As CLR is highly influenced by weather conditions, this study aimed to determine the best linearization model to estimate the CLR apparent infection rate, to correlate CLR infection rates with weather variables, and to develop and assess the performance of weather-based infection rate models to be used as a disease warning system...

Rice is generally grown under completely flooded condition and providing food for more than half of the world's population. Any changes in weather parameters might affect the rice productivity thereby impacting the food security of burgeoning population. So, the crop yield forecasting based on weather parameters will help farmers, policy makers and administrators to manage adversities. The present investigation examines the application of stepwise multiple linear regression (SMLR), artificial neural network (ANN) solely and in combination with principal components analysis (PCA) and penalised regression models (e...

Changes in non-invasive stress biomarkers were studied in shaded (n = 8) and non-shaded (n = 8) Holstein bull calves exposed to extreme heat load conditions in a continental region. Ambient temperature and humidity data were recorded for the S and NS hutch and exercise pen environments. Temperature-humidity-index (THI) was also calculated. Respiratory rate, rectal temperature, heart rate, and the root mean square of successive differences between R-R intervals (RMSSD) were recorded as animal-based indicators during three periods: (1) day 1, control day, during which all calves were shaded for 24 h (shade removal from non-shaded calves at 2400 h); (2) day 2, heat stress day, with shade over shaded calves; and (3) days 3-5, post-stress period, with shade over shaded calves...

The Spermophilus dauricus is a rodent species that feeds on the tender parts of plants and seeds. It is also a natural carrier of the hepatitis B virus and the main host of the plague bacillus Yersinia pestis threatening human health and the cultivated ecosystems. Based on ecological niche modeling (ENM) for the MaxEnt model and ArcGIS for the Spatial Analyst model, we quantified the potential risk zone and spatial pattern of the S. dauricus outbreak during 2000-2015. We analyze the temporal and spatial variation for different levels of risk zones...

Calculating many agroclimatic metrics, e.g., chill or heat accumulation in orchards, requires continuous records of hourly temperature. Such records are often unavailable, with farm managers and researchers relying on daily data or hourly records with gaps. While procedures for generating idealized temperature curves exist, interpolating hourly records has long been a challenge. The SolveHours procedure combines measured hourly temperatures, idealized daily temperature curves and proxy data to fill gaps in such records...

The length of the snow-free season is a key factor regulating plant phenology and shaping plant community composition in cold regions. While global warming has significantly advanced the time of snowmelt and the growth period at all elevations in the Swiss Alps, it remains unclear if it has altered the likelihood of frost risk for alpine plants. Here, we analyzed the influence of the snowmelt timing on the risk of frost exposure for subalpine and alpine plants shortly after snowmelt, i.e., during their most vulnerable period to frost at the beginning of their growth period...

The present paper aimed to show the thermoregulatory responses of locally adapted Morada Nova sheep with different coat colors that were exposed to direct solar radiation in an equatorial semiarid region. Animals were classified into four groups according to the coat color as follows: (1) dark red, (2) intermediate red, (3) light red, and (4) white coats. Forty Morada Nova ewes were observed in for 7 consecutive months. The experimental variables measured were rectal temperature (RT), skin surface temperature (ST), respiratory rate (RR), skin surface evaporation (CE), respiratory evaporation (RE), and heat exchange by convection (HC) and radiation (R)...

Human comfort in outdoor spaces (HCOS) is linked to people's psychological responses to environmental variables. Previous studies have established comfort ranges for these variables through interviews and questionnaires, reaching only limited populations. However, larger amounts of data would not only generate more robust results in local studies, but it would also allow for the possibility of creating an approach that could be applied to a wider range of weather conditions and different climates. Therefore, this study describes a new methodology to assess people's perception of weather based on human responses to weather conditions extracted from tweets, with the purpose of establishing comfort ranges for environmental variables...

Climate change is expected to influence plant productivity particularly through changes in the timing of budburst. Nonetheless, knowledge about the intraspecific variation of the timing of budburst and its relationship with climate is insufficient for most tree species. Based on the common garden experiments of Fagus crenata, we investigated the interrelationships between the day of budburst, cumulative degree-days (temperature sum), chilling duration, and photoperiod at the timing of budburst for the trees of different combinations of 11 sites of seed origin and seven experimental sites in Japan...

Climate sensitivity of populations at the margins of their distribution range is of key importance to understand species' responses to future warming conditions. Pinus cembra is of particular interest being a typical high-elevation taxon, spread with mostly scattered populations within its actual range, but still overlooked in traditional dendrochronological researches due to low tree-ring variability and climate sensitivity. With a different approach, we analyzed time series of xylem anatomical traits, split into intra-ring sectors, and used daily climate records over 89 years (1926-2014) aiming to improve the quality and time resolution of the climate/growth associations...

This article addresses the use of photographic comparison as a complementary visual appraisal method in an outdoor thermal perception survey. This survey was carried out during a Ph.D. research exploring how materials and vegetation influence thermal comfort in outdoor public spaces. Objective and subjective thermal perception parameters were combined and quantitative and qualitative research methods were used. The quantitative methods included microclimatic measurements, whilst the qualitative methods comprised observations and spatially localised interviews based on a questionnaire and the photographic comparison...

In order to provide a reference for reconstructing the paleoclimate of the northeastern Indian Ocean, 36 airborne pollen samples were analyzed using methods for airborne pollen, and 26 surface water samples were analyzed using a lab method for surface water. We found that little pollen is airborne over the Indian Ocean in spring, but airborne pollen types and concentrations can help to deduce paleomonsoon strength and direction. The conclusions included the following: (1) Pollen in the sediment was transported mainly via ocean currents instead of the early summer or spring wind...

Ruptured abdominal aortic aneurysm (rAAA) is a life-threatening condition with a high mortality rate. Seasonal variations in the incidence of rAAA and the influence of atmospheric pressure have been studied throughout decades; however, the conclusions are contradictory. Therefore, we aimed to conduct a meta-analysis and systematic review of literature on seasonal variations in rAAA incidence and the influence of atmospheric pressure. Studies investigating seasonal variations in rAAA incidence and influence of atmospheric pressure were retrieved...
