The Influence of Family Nurturing Environment on Children's Emotions and Behaviors

This paper explores the impact of family upbringing environment on children's emotions and behaviors, and analyzes its theoretical framework and research findings. Firstly, we delve into the concept of family upbringing environment, including factors such as family atmosphere, parenting styles, and family support systems. Subsequently, we systematically review relevant literature, discussing the mechanisms through which different family upbringing environments influence children's emotions and behaviors. We find that warm and supportive family environments typically promote healthy emotional development in children and contribute to the formation of positive behavioral patterns; conversely, hostile and indifferent family environments may lead to emotional problems and behavioral abnormalities in children. Further analysis indicates that the influence of family upbringing environment on children extends beyond emotions and behaviors, profoundly impacting their psychosocial development. Finally, this paper proposes suggestions for future research, aiming to deepen understanding of the comprehensive impact of family upbringing environment on children and provide more effective intervention strategies for promoting children's healthy development.

Naegleria fowleri 98 Percent Fatal a Comprehensive Survey

Naegleria fowleri, colloquially termed the "brain-eating amoeba," presents a formidable public health concern due to its astonishingly high fatality rate of 98%. This abstract provides a thorough examination of the various aspects surrounding Naegleria fowleri, encompassing its morphology, life cycle, transmission routes, clinical manifestations, diagnostic methods, treatment strategies, and preventive measures. Naegleria fowleri, an amoeboid protist, thrives in warm freshwater environments, predominantly in regions with elevated temperatures. Infections occur when contaminated water enters the nasal passages, leading to primary amebic meningoencephalitis (PAM), an acute and often fatal condition affecting the central nervous system. The clinical course of PAM is rapid, with symptoms escalating from initial flu-like manifestations to severe neurological impairment within days. Diagnosis of PAM remains challenging, relying on specialized laboratory techniques such as polymerase chain reaction (PCR) and immunofluorescence assays. Despite efforts to develop effective treatments, mortality rates remain alarmingly high, emphasizing the critical importance of preventive measures. Avoiding freshwater activities in warm, stagnant water bodies, utilizing nose clips or plugs during water-related activities, and ensuring proper disinfection of recreational water sources are key strategies in mitigating the risk of the risk of Naegleria fowleri infections and reducing its devastating impact on public health.

Associations between residential daytime indoor temperature and self-reported sleep disturbances in UK adults: A cross-sectional study

BackgroundIn the past few decades, research on the association between indoor temperature and sleep has primarily used laboratory rather than field data collected in epidemiological cohorts. MethodsSecondary data on 2493 individuals aged 43 years was obtained from the National Survey of Health and Development (NSHD). Logistic regression models were used to investigate the associations between temperatures (indoor at home, spot measurement when the nurses visited during the day; and outdoor, monthly average) and self-reported sleep disturbances, adjusting for socio-demographics, health variables, housing variables, and temperature-related variables. ResultsAssociations were found between daytime indoor temperature with difficulty initiating (OR: 0.95, 95%CI: 0.91–0.98) and maintaining sleep (OR: 0.96, 95%CI: 0.93–0.99). Compared with neutral indoor temperatures (17–28 °C), low indoor temperature (≤17 °C) was associated with difficulty initiating sleep (OR: 1.79, 95%CI: 1.21–2.65). Stratified analysis results across tertiles showed that associations with difficulty initiating (OR: 0.87, 95%CI: 0.77–0.99) and maintaining sleep (OR: 0.88, 95%CI: 0.79–0.98) were observed respectively in the lowest (≤20 °C) and highest tertile (≥23 °C) of indoor temperature. There was no association between outdoor temperature and self-reported sleep disturbances in this study. ConclusionIn this first UK-based epidemiology study investigating temperature and sleep, self-reported sleep disturbances were associated with residential daytime indoor temperatures. Low indoor temperature had significantly higher odds ratio for difficulty initiating sleep compared with the neutral indoor temperature. A warmer indoor environment might be more suitable for sleep maintenance than sleep initiation. Indoor temperature in this study was a superior indicator of sleep disturbances than outdoor temperature. Although these findings are based on a UK sample, they may be relevant to other high-income settings with similar housing stock and climatic conditions.

Acclimation to warming but not hypoxia alters thermal tolerance and metabolic sensitivity in an estuarine crustacean

Coastal species are challenged by multiple anthropogenic stressors. Plasticity may buffer the effects of environmental change, but investigation has largely been restricted to single-stressor performance. Multistressor studies have often been short-term and relatively less is known about the consequences of plasticity under one stressor for performance under another. Here, we aimed to test for the effects of thermal or hypoxic acclimation on thermal tolerance in the amphipod Gammarus chevreuxi. Animals were chronically exposed to raised temperature or hypoxia prior to determination of upper thermal limits and routine metabolic rate (RMR). Warm acclimation increased all metrics of thermal tolerance, but hypoxic acclimation had no effect. Different responses to the two stressors was also observed for the thermal sensitivity of RMR. Consequently, this species possesses the ability to increase thermal tolerance via plasticity in response to chronic warming but increasing duration of hypoxic episodes will not confer cross-tolerance to a warming environment.

Temperature-size responses during ontogeny are independent of progenitors' thermal environments.

Warming generally induces faster developmental and growth rates, resulting in smaller asymptotic sizes of adults in warmer environments (a pattern known as the temperature-size rule). However, whether temperature-size responses are affected across generations, especially when thermal environments differ from one generation to the next, is unclear. Here, we tested temperature-size responses at different ontogenetic stages and in two consecutive generations using two soil-living Collembola species from the family Isotomidae: Folsomia candida (asexual) and Proisotoma minuta (sexually reproducing). We used individuals (progenitors; F0) from cultures maintained during several generations at 15 °C or 20 °C, and exposed their offspring in cohorts (F1) to various thermal environments (15 °C, 20 °C, 25 °C and 30 °C) during their ontogenetic development (from egg laying to first reproduction; i.e., maturity). We measured development and size traits in the cohorts (egg diameter and body length at maturity), as well as the egg diameters of their progeny (F2). We predicted that temperature-size responses would be predominantly determined by within-generation plasticity, given the quick responsiveness of growth and developmental rates to changing thermal environments. However, we also expected that mismatches in thermal environments across generations would constrain temperature-size responses in offspring, possibly due to transgenerational plasticity. We found that temperature-size responses were generally weak in the two Collembola species, both for within- and transgenerational plasticity. However, egg and juvenile development were especially responsive at higher temperatures and were slightly affected by transgenerational plasticity. Interestingly, plastic responses among traits varied non-consistently in both Collembola species, with some traits showing plastic responses in one species but not in the other and vice versa. Therefore, our results do not support the view that the mode of reproduction can be used to explain the degree of phenotypic plasticity at the species level, at least between the two Collembola species used in our study. Our findings provide evidence for a general reset of temperature-size responses at the start of each generation and highlight the importance of measuring multiple traits across ontogenetic stages to fully understand species' thermal responses.

Group 2i Isochrysidales thrive in marine and lacustrine systems with ice cover

Global warming is causing rapid changes to the cryosphere. Predicting the future trajectory of the cryosphere requires quantitative reconstruction of its past variations. A recently identified sea-ice-associated haptophyte, known as Group 2i Isochrysidales, has given rise to a new sea-ice proxy with its characteristic alkenone distributions. However, apart from the occurrence of Group 2i Isochrysidales in regions with sea ice, and the empirical relationship between C37:4 alkenone abundance and sea-ice concentration, little is known about the ecology of these haptophyte species. Here, we systematically mapped the spatial and temporal occurrence of known Group 2i Isochrysidales based on environmental DNA in both marine and lacustrine environments. Our results indicate Group 2i is widely distributed in icy marine and lacustrine environments in both Northern and Southern Hemisphere, but is absent in warm environments. Temporally, Group 2i is part of the sea-ice algae bloom during the cold seasons, in contrast to other Isochrysidales that bloom in open waters during warm seasons. Our results indicate that ice is a prerequisite for the occurrence of the psychrophilic Group 2i haptophytes in marine and lacustrine ecosystems and further affirms its value for past ice reconstructions.

Genetic response of a perennial grass to warm and wet environments interacts and is associated with trait means as well as plasticity.

Potential for rapid evolution is an important mechanism allowing species to adapt to changing climatic conditions. Although such a potential has been largely studied in various short-lived organisms, to what extent we can observe similar patterns in long-lived plant species, which often dominate natural systems, is largely unexplored. We explored potential for rapid evolution in Festuca rubra, long-lived grass with extensive clonal growth dominating in alpine grasslands. We used field sowing experiment simulating expected climate change in our model region. Specifically, we exposed seeds from 5 independent seed sources to novel climatic conditions by shifting them along a natural climatic grid and explored genetic profiles of established seedling after 3 years. Data on genetic profiles of plants selected under different novel conditions indicate that different climate shifts select significantly different pools of genotypes from common seed pools. Increasing soil moisture was more important selective pressure than increasing temperature or interaction of the two climatic factors. This can indicate negative genetic interaction in response to the combined effects, or that the effects of different climates are interactive rather than additive. The selected alleles were found in genomic regions likely affecting function of specific genes or their expression. Many of these were also linked to morphological traits (mainly to trait plasticity) suggesting these changes may have a consequence for plant performance. Overall, these data indicate that even long-lived plant species may experience strong selection by climate, and their populations thus have the potential to rapidly adapt to these novel conditions.

Strong microwave squeezing above 1 Tesla and 1 Kelvin.

Squeezed states of light have been used extensively to increase the precision of measurements, from the detection of gravitational waves to the search for dark matter. In the optical domain, high levels of vacuum noise squeezing are possible due to the availability of low loss optical components and high-performance squeezers. At microwave frequencies, however, limitations of the squeezing devices and the high insertion loss of microwave components make squeezing vacuum noise an exceptionally difficult task. Here we demonstrate direct measurements of high levels of microwave squeezing. We use an ultra-low loss setup and weakly-nonlinear kinetic inductance parametric amplifiers to squeeze microwave noise 7.8(2) dB below the vacuum level. The amplifiers exhibit a resilience to magnetic fields and permit the demonstration of large squeezing levels inside fields of up to 2 T. Finally, we exploit the high critical temperature of our amplifiers to squeeze a warm thermal environment, achieving vacuum level noise at a temperature of 1.8 K. These results enable experiments that combine squeezing with magnetic fields and permit quantum-limited microwave measurements at elevated temperatures, significantly reducing the complexity and cost of the cryogenic systems required for such experiments.

Residents or Tourists: Is the Lactating Mammary Gland Colonized by Residential Microbiota?

The existence of the human milk microbiome has been widely recognized for almost two decades, with many studies examining its composition and relationship to maternal and infant health. However, the richness and viability of the human milk microbiota is surprisingly low. Given that the lactating mammary gland houses a warm and nutrient-rich environment and is in contact with the external environment, it may be expected that the lactating mammary gland would contain a high biomass microbiome. This discrepancy raises the question of whether the bacteria in milk come from true microbial colonization in the mammary gland ("residents") or are merely the result of constant influx from other bacterial sources ("tourists"). By drawing together data from animal, in vitro, and human studies, this review will examine the question of whether the lactating mammary gland is colonized by a residential microbiome.

Parental emotional warmth and non-suicidal self-injury among Chinese adolescents: The mediating effect of bullying involvement and moderating effect of the dark triad

Previous studies have mostly explored the relationship between negative parenting styles and non-suicidal self-injury (NSSI), while little research has investigated the role of parental emotional warmth in NSSI. The present study constructed two moderated mediation models and explored the effects of multiple factors, involving family, peer, and individual aspects, on NSSI. A random cluster sampling of 955 adolescents (490 boys, Mage = 13.33 years, SD = 1.29) was surveyed using questionnaires to measure parental emotional warmth, bullying perpetration and victimization, the dark triad, and NSSI. The results showed that parental emotional warmth was negatively associated with NSSI. Bullying perpetration and bullying victimization mediated the relationship between these two, respectively. Moreover, the dark triad moderated the relationships between bullying perpetration and NSSI, as well as bullying victimization and NSSI, and further moderated both mediating pathways. That is, for adolescents with lower levels of the dark triad, parental emotional warmth is more conducive to reducing the risk of NSSI by decreasing bullying involvement. Accordingly, there is a need for educators to provide youth with as much emotional support as possible and create a warm and healthy environment for growing up, which might help to prevent and mitigate their NSSI.

Does climate shape geographical morphological variation of spines in Neotropical spiny rats (Rodentia, Echimyidae, Trinomys)?

Abstract Flattened and flexible spiny hairs, the aristiforms, evolved independently in some lineages of rodents, but unlikely capable of causing severe damage to predators. Their biological roles are not yet clearly known and some different thermoregulatory functions have been proposed, often associated with severe climatic conditions but not yet tested. In this study we investigated whether climate may be a major factor shaping geographic variation of length and width of aristiform hairs of 2 species of Neotropical spiny rats of the genus Trinomys (Echimyidae) occurring in eastern Brazil: T. albispinus and T. setosus. Results revealed clinal variation in these hairs. While bioclimatic factors and geographic distance together accounted for up to a third of the morphometric variation, the exclusive impact of climate was limited, explaining only up to 3% of the observed variation. However, considering the close association between climate and geographic distance, the role of climate in shaping aristiform hair cannot be discounted. While our results did not fully support the hypothesis that well-developed, wide spiny hairs are selected for greater protection against rain for underhairs, they marginally supported their role in facilitating heat loss in warm environments by facilitating water condensation. More consistently, results show that narrow spiny hairs tended to evolve in cold environments, likely enhancing thermal insulation. The length of aristiform hair in T. albispinus also appeared to respond to this function, becoming longer in cold and high-altitude regions. However, we cannot rule out the possibility of an evolutionary response correlated with selection on underhairs. Future experimental studies should test the thermoregulatory function of flexible spiny hairs and investigate the geographic variation of these structures in other rodent species.

Initiation and suppression of Taconis oscillations in tubes with junctions and variable-diameter tube segments

Taconis oscillations represent spontaneous, usually unwanted excitations of acoustic modes in narrow pipes going from warm ambient environment into cold cryogenic space. These oscillations can drastically magnify heat leak and create vibrations undesirable for measurement instruments. In this study, modifications of a classical constant-diameter-tube Taconis setup are investigated. Specifically, variable-diameter tubes were found to strongly affect excitation, with wider tube segments in the warm environment encouraging oscillations, while additions of properly chosen pipe network configurations can supress the oscillations. The low-amplitude thermoacoustic theory, previously developed for thermoacoustic engines and refrigerators, was adapted for modelling Taconis phenomena, accounting for finite-length segments with temperature evolution where thermal-to-acoustic energy conversion takes place. Experiments were conducted using primarily hydrogen as a working fluid to validate theoretical predictions. With the rapid development of various hydrogen storage and transfer systems, it is expected that Taconis oscillations may become an issue, and this study provides an initial modelling framework to assess this phenomenon in hydrogen systems.

High CO2 exposure due to facemask wear is unlikely to impair cognition even in a warm environment after a long-term adaptation

There is a lack of consensus regarding the impact of elevated indoor CO2 exposure on cognition. COVID-19 provided an opportunity to study responses to long-term elevated CO2 exposure from facemask wear. Such an opportunity allows us to avoid exposing participants to elevated CO2 levels not typically experienced in real-life settings, potentially increasing the ecological validity of our experimental design. Further, the worsening warmness during summer necessitates studies and understanding of peoples’ cognition with combined stressors of both heat and CO2 accumulation. In this work, we recruited 60 college students to understand whether facemask wear elevates local CO2 levels and, if so, the extent to which it impacts cognition in warm conditions. Subjects remained in a controlled summer environmental room (temperature 31.5 °C, relative humidity 30 %) for 90 min with or without facemasks. Participants completed six cognitive tests in a random order and answered surveys using computer-based software. Ten experimental subjects had a second 30 min visit to measure CO2 concentration at the ala of the nose with and without surgical masks. The results show that wearing a surgical mask sharply increased CO2 concentration near the nose by 15,000 ppm. Our analysis showed that the experimental group with facemask wear did not exhibit significantly different cognition performance except for short-term memory which was higher instead of lower than the control group. Participants with facemask wear showed significantly lower risk-taking, possibly attributed to thermal discomfort. Nevertheless, no significance in cognition or decision-making was observed after controlling the familywise error rate using the Bonferroni correction. We hypothesize that the insignificant difference might be caused by adaptation to long-term wear and high CO2 exposure in daily life during COVID-19, which cannot be revealed in the studies prior to the pandemic.

Development of a novel composite phase change material based on paints and brick for energy storage applications in agricultural greenhouses

This study addresses challenges associated with supercooling, phase separation, and inadequate thermal properties in Na2SO4·10H2O (SSD) by expanding the application of inorganic hydrate salt phase change materials within agricultural greenhouses. A novel composite phase change material, Na2SO4·10H2O-Al2O3 (NAPCM), was successfully synthesized using the vacuum impregnation method. NAPCM was strategically incorporated into paints and hollow bricks, leading to the creation of innovative phase change paint and phase change bricks designed for efficient thermal energy storage in agricultural greenhouses. The investigation revealed the homogeneous dispersion of porous Al2O3 particles in SSD, effectively preventing phase separation in NAPCM and ensuring its durable shape stability. The interaction between SSD and porous Al2O3 remained purely physical, with porous Al2O3 acting as an effective modifier to adjust various thermal properties of SSD. Optimal mass ratio determination for the combination of paint and NAPCM particles resulted in a 9:1 ratio, ensuring the uniform distribution of NAPCM particles within the paint matrix. This achieved a particle size averaging 290.93 μm with no discernible leakage features. The phase change paint exhibited an impressive solid content of 56.62 %, demonstrating exceptional resistance to water, alkali, salt, and abrasion. In thermal plate testing, the phase change paint significantly decelerated the heating rate. Infrared thermal imaging observations depicted circular areas with temperatures notably lower than their surroundings, indicating NAPCM's ability to impede heat absorption during the heating process, thereby reducing the rate of temperature change. The phase change paint also exhibited a slower cooling rate in the cooling test. Simultaneously, phase change bricks demonstrated superior thermal insulation compared to ordinary bricks. Throughout the heat storage phase, the temperature of the phase change greenhouse wall was lower than that of an ordinary greenhouse, while in the heat release phase, it was higher. The phase change greenhouse, relative to its ordinary counterpart, demonstrated superior insulation effects, creating a warm environment conducive to plant growth. This advancement enhances the energy storage performance of agricultural greenhouses, providing a novel solution for improving energy efficiency and environmental sustainability.

Long-term species-level observations indicate the critical role of soil moisture in regulating China's grassland productivity relative to phenological and climatic factors

As a sensitive indicator of climate change and a key variable in ecosystem surface-atmosphere interaction, vegetation phenology, and the growing season length, as well as climatic factors (i.e., temperature, precipitation, and sunshine duration) are widely recognized as key factors influencing vegetation productivity. Recent studies have highlighted the importance of soil moisture in regulating grassland productivity. However, the relative importance of phenology, climatic factors, and soil moisture to plant species-level productivity across China's grasslands remains poorly understood. Here, we use nearly four decades (1981 to 2018) of in situ species-level observations from 17 stations distributed across grasslands in China to examine the key mechanisms that control grassland productivity. The results reveal that soil moisture is the strongest determinant of the interannual variability in grassland productivity. In contrast, the spring/autumn phenology, the length of vegetation growing season, and climate factors have relatively minor impacts. Generally, annual aboveground biomass increases by 3.9 to 25.3 g∙m2 (dry weight) with a 1 % increase in growing season mean soil moisture across the stations. Specifically, the sensitivity of productivity to moisture in wetter and colder environments (e.g., alpine meadows) is significantly higher than that in drier and warmer environments (e.g., temperate desert steppes). In contrast, the sensitivity to the precipitation of the latter is greater than the former. The effect of soil moisture is the most pronounced during summer. Dominant herb productivity is more sensitive to soil moisture than the others. Moreover, multivariate regression analyses show that the primary climatic factors and their attributions to variations in soil moisture differ among the stations, indicating the interaction between climate and soil moisture is very complex. Our study highlights the interspecific difference in the soil moisture dependence of grassland productivity and provides guidance to climate change impact assessments in grassland ecosystems.

Urban hedges facilitate spontaneous woody plants

Most trees and other woody plants growing within urban areas are deliberately cultivated native or non-native plants. Opportunities for spontaneous establishment and spread of woody species are scarce in an urban environment, especially if the establishment begins from seeds. We hypothesized that urban hedges might offer safe sites for the spontaneous establishment of woody plants, which reach the hedges through propagule dispersal. We recorded the species composition of urban hedges in Maribor (NE Slovenia) in a gradient from the city centre outwards and evaluated the species’ invasive potential and ecological requirements, along with hedge characteristics. Results show that hedges facilitated the survival and growth of 69 woody plants from 28 families. Among these, 62% were non-native and 10% were locally invasive. Most of recorded non-native woody plants were ornamentals. Moreover, for native species, we show that the stressful, warmer urban environment mostly facilitates the establishment of species in the genera Hedera and Acer. Comparison of non-native and native plants showed the former are more drought and heat tolerant than the latter. We further show that with distance from the city centre, the number of bird-dispersed species increases, in contrast to the wind-dispersed species. Additionally, our results suggest evergreen hedges may be less permeable to wind-dispersed propagules than deciduous hedges. Next, we stress the importance of paved surfaces and urbanization, selecting for the thermophile, drought tolerant, wind-dispersed woody plants that find refuge in urban hedges. Our results suggest urban hedges can facilitate the establishment of a wide range of woody plant species.

Enhancing Nurse's Knowledge- A Programme on Prevention of Neonatal Hypothermia

Introduction: Newborns are less efficient in regulating their body temperature due to poor their heat-regulating mechanisms. Thermal stability of the neonate is crucial, and awareness of the significance of a warm environment has resulted in better care of the neonate. Objective: The study aimed to determine the efficacy of a structured teaching programme regarding the prevention of neonatal hypothermia among nurses. Material and Methods: A pre-experimental, (one-group pre-test and post-test) research design was conducted in the Government Multispeciality Hospital, Chandigarh, India. Sixty nurses were chosen through the non-probability purposive sampling technique. The instrument employed for the study includes demographic variables and a self-structured knowledge questionnaire. Results: The pre-test degree of knowledge regarding the prevention of neonatal hypothermia among 60 nurses shows that 58.3% had fair knowledge and 41.7% had good knowledge. The post-test knowledge scores showed that out % of 60 nurses, 75% possessed very good knowledge, while 25% had good knowledge. The comparison of both tests' knowledge scores using the Wilcoxon rank test resulted in a p-value = <0.001, which indicates that the result is highly significant. Furthermore, the chi-square test was applied to find out whether or not there was a statistical association between the knowledge scores and their demographic variables. It was determined that the p-value for both the knowledge scores was found to be greater than 0.05 which is insignificant. Hence, there is no association found between both sets of knowledge scores with their demographic variables. Conclusion: The structured teaching programme culminated in enhancing knowledge among nurses regarding preventing neonatal hypothermia.

PENGEMBANGAN KUALITAS PRIBADI KONSELOR SECARA PROFESIONAL DALAM PELAYANAN BIMBINGAN KONSELING: LITERATURE REVIEW

The goal in providing counseling services is to provide conditions which can help clients develop psychological strength to evaluate his behavior now, and can get that behavior now and can get behavior more effective. The process of learning to behave effectively is facilitated by creating warm counseling environment and application of various counseling procedures. To achieve this requires quality interpersonal relationships both between counselor and counselee. Counseling as a profession depicted by the counselor's appearance. A professional counselor is a figure who can present himself as a role model. Among competencies counselor, the most important thing is the personal quality of the counselor, because the counselor used as a person who must be able to display his true identity complete, precise and meaningful, and build good interpersonal relationships so that it becomes the driving force for the success of the service. Personal counselor is wrong one of them is an "instrument" that can determine positive results in counseling process, because the core of the therapeutic process in counseling is the relationship built between the counselor and the counselee. So personal qualities counselor is essential for counselors to achieve their goals optimal in the counseling process.

Biological soil crusts are more prevalent in warmer and drier environments within the Great Basin ecoregion: implications for managing annual grass invasion

Biological soil crusts (biocrusts) can thrive under environmental conditions that are stressful for vascular plants such as high temperatures and/or extremely low moisture availability. In these settings, and in the absence of disturbance, cover of biocrusts commonly exceeds cover of vascular plants. Arid landscapes are also typically slow to recover from disturbance and prone to altered vegetation and invasion by exotic species. In the sagebrush ecosystems, cover of annual, exotic, invasive grasses are lower where cover of biocrusts and vascular plants are greater, suggesting that biocrusts play a role in helping arid sites avoid conversion to dominance by invasive grasses. The conceptual framework for assessing ecological resistance and resilience (R&R) is used across the region to estimate the risk of invasion by annual grasses and the likelihood of recovery of native plants following disturbance. However, this framework does not currently account for biocrusts. We used data collected by the Bureau of Land Management Assessment, Inventory, and Monitoring program to relate biocrusts, specifically the presence of lichens and mosses, to the R&R framework. Lichens frequently occur on warm, dry sites, classified as lower R&R. Mosses frequently occur on sites classified as moderate or moderately low R&R. Without management practices that favor biocrusts in low‐moderate R&R, these areas may be more vulnerable to transitioning from being dominated by shrubs to annual grasses. Under climate change scenarios, the area occupied by lower R&R sites is likely to increase, suggesting that the role of biocrusts in maintaining site resistance to invasion may also increase.

Global meta-analysis reveals overall higher nocturnal than diurnal activity in insect communities

Insects sustain key ecosystem functions, but how their activity varies across the day–night cycle and the underlying drivers are poorly understood. Although entomologists generally expect that more insects are active at night, this notion has not been tested with empirical data at the global scale. Here, we assemble 331 quantitative comparisons of the abundances of insects between day and night periods from 78 studies worldwide and use multi-level meta-analytical models to show that insect activity is on average 31.4% (CI: −6.3%–84.3%) higher at night than in the day. We reveal diel preferences of major insect taxa, and observe higher nocturnal activity in aquatic taxa than in terrestrial ones, as well as in warmer environments. In a separate analysis of the small subset of studies quantifying diel patterns in taxonomic richness (31 comparisons from 13 studies), we detect preliminary evidence of higher nocturnal richness in tropical than temperate communities. The higher overall (but variable) nocturnal activity in insect communities underscores the need to address threats such as light pollution and climate warming that may disproportionately impact nocturnal insects.
