Analysis of the Distribution Pattern of Asparagus in China Under Climate Change Based on a Parameter-Optimized MaxEnt Model

Asparagus (Asparagus officinalis L.) has high health and nutritional values, but the lack of scientific and rational cultivation planning has resulted in a decline in asparagus quality and yield. Important soil, climatic, anthropogenic, and topographic environmental factors influencing the distribution of asparagus cultivation were chosen for this study. The Kuenm package in the R language (v4.2.1) was employed to optimize the maximum entropy model (MaxEnt). Pearson’s correlation analysis, optimized MaxEnt, and geographic information spatial technology were then utilized to identify the main environmental factors that influence suitable habitats for asparagus in China. Potential distribution patterns, migration, and changes in trends concerning the suitability of asparagus in China under various historical and future climate scenarios were modeled and projected. Human activities and climate factors were found to be the primary environmental factors that influence the suitability distribution of asparagus cultivation in China, followed by soil and topographic factors. Historical suitable habitats covered 345.6 × 105 km2, accounting for 36% of China. These habitats are projected to expand considerably under future climatic conditions. This research offers a basis for the rational planning and sustainable development of asparagus cultivation.

Characteristics of the allergic disorder and sensibilization spectrum distributions in the Russian Federation taking into account climatic and geographical features of the regions

BACKGROUND: Environmental factors have a direct impact on the course and spread of allergic disorders. In recent decades, there has been an increase in the number of patients with allergic pathology, which is partly due to global environmental changes on the planet and insufficient consideration of the specific climatic and geographic environmental factors of the region where the patient lives. AIM: To study the characteristics of epidemiology, etiology and clinical course of allergic disorders in different regions of the Russian Federation. MATERIALS AND METHODS: To achieve this goal, a questionnaire survey of the Chief Consultants was conducted in 2019. Questionnaires were sent to all district, regional, republican centers, and cities of federal significance. The received data were analyzed and structured. RESULTS: Responses to the questionnaires were received from 49 regions of the Russian Federation, where a total of 1,468,105 patients with allergic diseases were registered during the study period. Significant discrepancies in the distribution of allergic disorders and the spectrum of etiologically significant allergens were revealed in different regions of the Russian Federation, reflecting their climatic and geographical peculiarities. There is an increase in respiratory forms of allergy, multisensitization and multi-organ allergic lesions. The Ural Federal District has the lowest number of cases of allergic rhinitis (p = 0.001) among the studied regions, and bronchial asthma is more common than other forms of respiratory allergy (p 0.001), while in the Southern Federal District the prevalence of this disease was statistically significantly lower than in the northern regions (p 0.001). Atopic dermatitis was more frequently registered in the Volga and Far Eastern Federal Districts (p = 0.009, p = 0.012), food allergy – in the Volga and Northwestern Federal Districts (p = 0.008, p = 0.003). In the North Caucasian and Siberian Federal Districts, food allergy was diagnosed least frequently (p = 0.001, p = 0.002). The Northwestern Federal District registered the smallest number of patients with sensitization to house dust allergens (p 0.001), and the Southern Federal District – to house dust mites (p = 0.004). The lowest number of patients with sensitization to weed pollen allergens was noted in the Northwestern Federal District (p 0.001). The Southern and North Caucasian Federal Districts dominate in terms of sensitization to weed pollen allergens (p 0.001, p = 0.001) and show a low percentage of sensitization to tree allergens (p 0.001) compared to other federal districts. Low sensitization of patients to mold allergens is noted in the Ural Federal District (p 0.001). The highest proportion of insect allergy is noted in the Siberian (p = 0.001), and the lowest – in the Central Federal District (p 0.001). The North Caucasian Federal District showed the lowest percentage of sensitization to food allergens (p = 0.04). Low availability of specialized care and insufficient prescription of pathogenetic allergen-specific immunotherapy were found in all federal districts of the Russian Federation. CONCLUSION: Different climatic and geographic regions of the Russian Federation differ from each other in the structure of allergic diseases and sensitization spectrum, which should be taken into account in the development of preventive, diagnostic and therapeutic measures in these territories.

The combined effects of climate, soil, and rhizospheric microorganisms determine the quality and suitable production zones of Stellaria dichotoma L. var. lanceolata Bge. in China

BackgroundStellaria dichotoma L. var. lanceolata Bge. (S. lanceolata) is a psammophytic plant endemic to the northwest region of China and has now developed into a cultivated economic crop. It is the original plant species used in traditional Chinese medicine as Yinchaihu. Recently, the lack of scientifically guided production zoning has exacerbated the arbitrary introduction and expansion of S. lanceolata cultivation, resulting in significant changes to its habitat and quality.MethodsThis study utilizes distribution data of wild S. lanceolata along with data from 33 environmental factors to analyze the primary habitat factors influencing the species' distribution using the Maxent model, simulating both current and future suitable production zones. Additionally, amplicon sequencing was employed to investigate changes in rhizospheric soil microorganisms across different cultivation sites and years. Furthermore, metabolomics, near-infrared spectroscopy, and the quantification of active ingredient content were used to assess the effects of various suitable zones on S. lanceolata.ResultsThe migration trends of S. lanceolata toward the central and eastern regions of Inner Mongolia revealed that elev, bio_4, bio_13, bio_11, and S_clay are the primary ecological and soil factors influencing suitability zoning, contributing a cumulative rate of 80.5%. The rhizosphere microbial environment shifted significantly from high to medium suitability habitats. As cultivation duration increased, the diversity of fungi and bacteria and the functional genera within the rhizosphere exhibited significant changes. Notably, there were substantial alterations in metabolic processes and substance accumulation during the transition from high to medium and low suitability zones, resulting in the identification of 281 and 370 differential metabolites, respectively. Additionally, the near-infrared spectral characteristics and active ingredient content of S. lanceolata in high suitability zones displayed distinct specificity. In particular, the contents of total flavonoids (2.772 mg·g−1), dichotomines B (0.057 mg·g−1), and quercetin-3-O-β-D-glucoside (0.312 mg·g−1) were notably higher, with the overall quality score surpassing that of other suitable zones. ConclusionThis study revealed the key climatic, soil, and rhizosphere microbial environmental factors influencing the quality formation of S. lanceolata and the selection of suitable production zones, offering guidance for sustainable development and production zone planning.Graphical

Epidemiological characteristics of respiratory syncytial virus infection in children in Nanchang and its correlation with climate environmental factors

To explore the epidemiological characteristics of respiratory syncytial virus (RSV) infection in children in Nanchang and its correlation with climate environmental factors. The clinical data were collected from children with acute respiratory infection in Nanchang who were tested for RSV at Jiangxi Provincial Children's Hospital from January 2019 to December 2023, along with climate environmental data for the same period. The epidemiological characteristics of RSV and their correlation with climate environmental factors were investigated. A total of 178 127 children underwent RSV testing from January 2019 to December 2023, with a positive detection rate of 8.35% (14 873/178 127). The positive detection rate in males was 8.92% (10 137/113 660), which was higher than that in females (7.35%, 4 736/64 467). The differences in RSV positive detection rates among different age groups were statistically significant (P<0.001), with the highest rate observed in the 0 to <3 months age group (14.38%, 3 328/23 142). Peaks in RSV positive detection occurred during winter and spring periods in 2019, 2020, and 2022, while in 2023, it occurred in spring and summer periods, with no seasonality noted in 2021. The RSV positive detection rate showed a positive correlation with average humidity, average atmospheric pressure, monthly PM2.5, and monthly carbon monoxide levels (P<0.05), while it showed a negative correlation with average wind speed, average temperature, and maximum 8-hour ozone levels (P<0.05). In Nanchang, the RSV positive detection rate in children with acute respiratory infection is higher in males than in females. Among children of all age groups, the infants aged 0 to <3 months have the highest detection rate of RSV. RSV infection predominantly occurs in winter and spring periods. Lower temperatures, lower wind speeds, higher humidity, and elevated levels of PM2.5 and carbon monoxide may increase the risk of RSV infection in children.

DEVELOPMENT OF VEGETATION PHENOPHASES IN SOME PLUM CULTIVARS GROWN IN THE CRAIOVA AREA

The paper studied the development of the vegetation phenophases in three plum cultivars (ˈAndreeaˈ, ˈRecordˈ and ‘Čačanská lepotica’), analyzing how climatic variations and environmental factors affect their development. The BBCH scale was used to record the different phenophases. The number of days from November 1 to budding, the duration of budding, the duration of the flowering period, the number of days from the appearance of the fruits to the ripeness for consumption were calculated and it was found that the phenological stages occurred without too great differences from one cultivar to another. This is due, on the one hand, to the fact that the three cultivars were grafted on the same rootstock, and on the other hand, to the close fruit ripening period.

Comparative Analysis of Some Morpho-cultural Characters of Venturia inaequalis (Apple Scab Pathogen) under Kashmir Conditions

Apple (Malus × domestica Borkh.) represents one of the most widely cultivated and economically important temperate fruit crops in the world. However, its cultivation faces significant challenges due to various fungal pathogens, particularly apple scab inflicted by Venturia inaequalis, which has a profound impact on the yield and quality of apple, resulting in substantial economic loss. The pervasive nature of V. inaequalis and its ability to damage crops poses a serious threat to sustainable apple production. In this study, the morpho-cultural characteristics of V. inaequalis were systematically analyzed and compared between the Shopian and Baramullah districts of the Kashmir Valley. Ten isolates from each district were grown on Malt Extract Agar (MEA) and Potato Dextrose Agar (PDA) for comparative analysis. The colonies were characterized by a compact hue ranging from greyish-green to blackish and exhibited a densely velvety texture. Mycelial growth was predominantly aerial, with some isolates displaying partial irregularity in colony margins, while others exhibited greater uniformity. The mean colony radii for potato dextrose agar and malt extract agar media was measured as 23.01 mm and 28.50 mm for the Shopian district, and 28.09 mm and 33.33 mm for the Baramullah district, respectively. The mean conidial spore density was recorded at 27.87 spores/cm² for the Baramullah district and 34.67 spores/cm² for the district Shopian, respectively. This variation could be attributed to several factors, including genetic diversity within the pathogen populations, differences in altitude, climate, and other environmental factors, the selection pressure exerted by fungicide applications, the emergence of novel pathogen races, and phenotypic plasticity driven by the differing agricultural practices and microclimatic conditions in the respective regions.

PV Based Single Stage Cascaded Seven Level Modular Multilevel Converter with ZSV Control for Grid Interfaced System

Objectives: Climatic perturbation and environmental factors affect solar power generation. When these solar panels are connected to the grid it causes power quality issues such as voltage harmonics, voltage distortion, etc. These problems are addressed in this paper using a distributed MPPT algorithm.

Partial shading is conquered by using distributed MPPT. Findings: The simulation of the proposed system is performed for a three-phase system. The three-phase Cascaded Modular Multilevel Converter is connected to the grid through two loads which are controlled by a Zero Sequence Voltage Controller. Power quality parameters such as current, harmonics, and power are analyzed for the proposed system. Novelty: THD analysis for a five-level cascaded H bridge converter and the proposed systems are compared and presented. Keywords: Photo voltaic, Cascaded seven-level modular multilevel converter, Zero sequence control, Maximum power point tracking, Voltage Source Converter

Skin diseases among adults in Tasiilaq, East Greenland

ABSTRACT Cold climate and unique genetic and environmental factors may influence the prevalence of skin diseases in Greenland. However, there is a lack of epidemiological studies on skin diseases in the adult Greenlandic population. To address this unmet need a cross-sectional study, run by dermatologists from Denmark, the UK, and Switzerland estimated the prevalence and clinical manifestations of skin diseases among adults in East Greenland in May 2022. All adults ≥18 years in the town of Tasiilaq were invited, and 295 individuals aged 18–78 years participated (22.5% of the overall adult population in Tasiilaq). Two-hundred and three participants (69%) had visible signs of current skin disease, and among these, 242 cases of dermatoses were identified. The most common skin diseases were hand eczema (22.4%), lichen simplex (9.5%), discoid eczema (7.1%), psoriasis, atopic dermatitis and acne vulgaris (5.8% each). Scabies was the most frequent infectious skin disease (4.4%). No cases of skin cancer were identified. Atopic dermatitis and psoriasis presented with disease that was of limited extent and different from the classical presentations. Skin diseases showed a high prevalence among adults in East Greenland, and some of them were severe. This indicates a noteworthy public health problem that warrants better access to dermatologist support.

Spatial and Temporal Patterns of Vegetation Water Use Efficiency and Its Response to Climatic and Environmental Factors in Gansu Province

Vegetation water use efficiency (WUE) is a crucial indicator for elucidating the interconnections between the carbon and water cycles of ecosystems and for discerning the response of vegetation ecosystems to climate change. Gansu Province in northwestern China is facing significant ecological water-related challenges. However, the response of vegetation WUE to climate environmental factors in this region remains unclear. In this study, the MODIS vegetation gross primary productivity (GPP) and evapotranspiration (ET) datasets were used to calculate the vegetation WUE in Gansu Province and, combined with meteorological data, Theil–Sen median trend analysis and partial correlation analysis were used to determine the spatial and temporal characteristics of vegetation WUE in this region and its response to climate environmental factors. Finally, the random forest model was used to rank the importance of climate environmental factors. The results indicate the following: (1) The average values of vegetation WUE, GPP, and ET in Gansu Province from 2000 to 2020 were 1.46 gC·mm−1·m−2, 510.22 gC·m−2, and 343.68 mm, respectively, and their spatial distribution was high in the southeast and low in the northwest, which was closely related to the distribution of vegetation in the region. (2) Over the past 20 years, the vegetation WUE in this region showed a slowly decreasing trend in general, with a decrease rate of 16.57%. There were significant differences in the WUE of different vegetation types, among which forest WUE was the highest and grassland WUE the lowest. (3) The trend prediction of WUE in Gansu Province was performed by using the rescaled extreme difference method, and the Hurst index was 0.45, which means that the vegetation WUE in this region is expected to increase in the future. (4) In general, precipitation was the main factor influencing the change in vegetation WUE in Gansu Province, followed by vapor pressure deficit (VPD), temperature, and soil moisture. This study provides strategy support for the coupling process of vegetation ecosystems and the sustainable development of agriculture and animal husbandry in Gansu Province and has scientific reference value for promoting and planning the sustainable development of vegetation in arid and semi-arid areas.

Monitoring Land Cover Dynamics and Forest Degradation in South Sumatra Peatlands from 2015 to 2023 by Remote Sensing Application

Most Peat Hydrological Units (PHU) in South Sumatra, Indonesia, have been threatened by degradation from climate changes, human activities, and environmental factors. This study mapped land cover using Random Forest Classification and identified forest degradation using NDFI (Normalized Difference Forest Index) change analysis in several PHUs of the South Sumatra peatland from 2015 to 2023. We combined Sentinel-1, Sentinel-2, and Landsat-8 data for the land cover classification. Meanwhile, we utilized Landsat-8 to identify forest degradation. Our findings indicate that tree cover significantly decreased in 2015, 2019, and 2023, coinciding with severe drought conditions driven by El Niño events. A significant decrease in forest cover in 2019 was suggested by low tree cover, up to 47.1% of the total area of 1.054 million ha. Therefore, grassland and bare/sparse vegetation had more significant coverage percentages, reaching 22.89% and 11.40%, respectively, in 2019. Deforestation varied but generally decreased from 2015 to 2023, according to the analysis of NDFI changes. Vegetation regrowth increased notably from 2016 to 2020 and remained relatively stable afterward. In addition, forest disturbance decreased from 2015 to 2020 but slightly increased in the last few years. Although two PHUs have encountered more severe degradation, their peatland ecosystems included inside them have distinct characteristics. Specifically, the PHU of Sungai Saleh – Sungai Sugihan encompasses cultivated areas, whereas the PHU of Sungai Sugihan – Sungai Lumpur comprises protected areas. These findings highlight the need for restoration and sustainable land management to prevent further degradation

The genetic diversity and evolution analysis of the Hainan melioidosis outbreak strains

Melioidosis is a zoonotic disease, with its outbreaks being rare and indicative of an unusual concurrence of extreme climate and natural environmental factors. An outbreak of melioidosis cases emerged in Hainan following Typhoon “Dianmu” from October to December 2021, presenting an opportunity to identify the environmental sources of infection for these cases due to its nature as a well-defined point-source cluster. To investigate the relationship between the occurrence of these melioidosis cases and the environment, we extracted the entire genome of 25 clinical strains and conducted MLST typing, followed by whole genome sequencing and analysis of molecular genetic information for four ST46 genotypes from these strains. Phylogenetic and evolutionary relationships between Hainan sequence types (STs) and those found in other endemic regions were analyzed using IslandPath-DIMO, PHASTER, e-BURST, PHYLOViZ, and the maximum likelihood method. Notably, a total of 25 clinical strains were identified, encompassing 12 STs (ST46, ST1105, ST1991, ST30, ST1992, ST50, ST164, ST55, ST70, ST1993, ST1545, and ST58), with ST1991, ST1992, and ST1993 being newly discovered subtypes. PHYLOViZ clustering analysis divided the strains into two groups (A and B), both closely related to the Asian region. Phylogenetic tree analysis further revealed that most of the strains in this study were closely related to those found in Australia and Thailand. Analysis of patient information and visits to their residences suggested that contaminated water sources might be the primary source of infection during this outbreak.Our findings underscore that extreme weather events, such as typhoons, significantly increase the infection rate of B. pseudomallei, along with its genetic diversity, necessitating additional prevention strategies to control these B. pseudomallei infections.

Sustainable investments in volatile times: Nexus of climate change risk, ESG practices, and market volatility

Climate change poses an unprecedented threat to global stability, presenting complex political, economic, and social risks. As financial markets become increasingly intertwined with sustainability considerations, understanding the implications of climate risk is paramount. This study investigates the relationships between climate change risk (CCRISK), environmental, social, and governance (ESG) factors, and the United Kingdom's stock market volatility (SMVOL). Using data from 2012 to 2021, we employ a robust analytical approach, including ordinary least squares and a generalised method of moments, to assess these relationships. Our findings reveal several key insights. First, we prove a positive and statistically significant relationship between CCRISK and SMVOL, indicating that firms with higher CCRISK tend to exhibit higher SMVOL. Second, we demonstrate a negative and statistically significant relationship between ESG scores and SMVOL, suggesting that firms with higher ESG scores tend to experience lower SMVOL. Furthermore, we introduced a moderation analysis examining how specific ESG dimensions moderate the CCRISK-SMVOL relationship. Our results reveal nuanced interactions, emphasising that different ESG dimensions influence the relationship differently. The findings offer strategic insights for investors, policymakers, and the advancement of sustainable finance.

Features of Coronary Atherosclerosis in Patients with Coronary Artery Disease Residing in the Far North

Aim: To evaluate the features of coronary artery disease (CAD) in patients in the Far North and determination of the potential impact of extreme climatic factors on the development of coronary atherosclerosis. Material and Methods. Using the “Register of performed coronary angiography operations”, 5,679 patients with coronary artery disease were selected, who underwent coronary angiography at the Tyumen Cardiology Research Center. The main study group consisted of 2,590 patients permanently residing in the YamaloNenets Autonomous Okrug and 3,089 patients residing in the South of the Tyumen Region. Results. Patients with permanent residence in the Yamalo-Nenets Autonomous Okrug were on average younger (53.20 ± 7.49 versus 56.79 ± 8.34 years, p &lt; 0.001), men were more common among them. In the extreme North there were more smokers (40.7 vs. 32.0%, p &lt; 0.001) and alcohol users (19.7 vs.15.0%, p &lt; 0.001), and more frequent myocardial infarction in anamnesis (57.1 vs. 48.2%, p &lt; 0.001). At the same time, in patients permanently residing in the South of the Tyumen Region, a burdened hereditary history of CAD was more often determined, and the frequency of arterial hypertension and dyslipidemia was higher. In groups balanced by baseline clinical and demographic characteristics, including CAD risk factors, patients from the Yamal-Nenets Autonomous Okrug had more frequent lesions of the three main coronary arteries: anterior descending artery (42 vs. 35%, p &lt; 0.001), circumflex artery (25 vs. 23%, p = 0.038) and right coronary artery (42 vs. 38%, p = 0.007). It should be noted that in balanced groups in patients permanently residing in the Far North, occlusive lesions of the coronary arteries were statistically significantly more likely to be determined (54 vs. 47%, p &lt; 0.001). Also, between the compared groups, statistically significant differences were found in the type of left ventricle (LV) myocardial remodeling, but these differences were not determined in the balanced groups. Also, in the group of patients permanently residing in the Far North, there was a trend towards a decrease in the LV ejection fraction (53.6 ± 8.6% vs. 54.2 ± 8.7, p = 0.074).Conclusion. In patients with verified coronary artery disease living in the Far North, a more frequent and pronounced atherosclerotic lesion of the coronary bed is determined. These pathological changes are probably due to the complex impact of unfavorable natural and climatic environmental factors.

Application and efficacy of beidellite clay for the adsorption and detoxification of deoxynivalenol (vomitoxin)

The incidence of mycotoxin occurrence throughout the entire lifespan of some agricultural products could be due to climatic conditions and environmental factors (including high temperature, drought, and heavy rainfall) that enhance growth of fungi. Deoxynivalenol (DON) which is also referred to as vomitoxin is a mycotoxin produced from many Fusarium species. DON ranks high among the prominent mycotoxins in cereal products and is a ubiquitous toxin in livestock feeds. DON's adverse effects present major health challenges in both livestock and humans. The use of natural sorbents including smectite clays, is an economically feasible strategy to mitigate mycotoxin toxicities. Previous studies have demonstrated the potential of edible clays as protective components of human food and animal feed to alleviate toxicity associated with short-term exposure to mycotoxins including DON. Hence, this study was designed to investigate the sorption mechanisms of DON onto the binding surfaces of beidellite clay, assessing essential binding parameters such as enthalpy, free energy, binding capacity, affinity, and plateau surface density. These markers were used to predict availability of DON under the experimental conditions. Furthermore, the protection of beidellite clay against DON-induced toxicity was carried out using living organisms susceptible to DON toxicity, including Hydra vulgaris and Lemna minor. These studies investigated the dose-dependent detoxification of DON by 0.05–2 % inclusion of beidellite. Beidellite exhibited more than 75 % protection in Lemna minor and 53 % in Hydra vulgaris validating that this clay is effective in detoxifying DON. During emergencies, or after disasters, inclusion of edible clay like beidellite in food, water or capsules could reduce bioavailability of DON and halt potential exposures to humans and animals.

Сравнительный анализ показателей системы внешнего дыхания у жителей-северян в возрастном аспекте

This study aimed at the specific performance of respiration system based on the ontogeny. Four hundred and fifty-two male residents of Magadan aged 15-74 participated in a comprehensive age-associated survey that involved 4 groups: adolescents, early adults, workable men of mature age and the elderly. The lungs volumetric and velocity characteristics were analyzed using computer spirometry. Most indicators of external respiration proved to be significantly age specific. The maximum values were observed in the early adulthood followed by a fall in men of older age groups. The revealed changes indicated lowered reserve capabilities of the respiration performance with increasing duration of residence under the North conditions and suggested reduced adaptabilities of the body owing to the chronic adverse effects of natural and climatic environmental factors. Keywords: North, adaptation, respiration system, men.

Predicting the Potential Distribution of Hypericum perforatum under Climate Change Scenarios Using a Maximum Entropy Model.

H. perforatum, as one of the Traditional Chinese Medicinal materials, possesses a variety of pharmacological activities and high medicinal value. However, in recent years, the wild resources of H. perforatum have been severely depleted due to global climate change and human activities, and artificial cultivation faces problems such as unstable yield and active ingredient content. This poses a serious obstacle to the development and utilization of its resources. Therefore, this experiment took H. perforatum as the research object and used 894 distribution records of H. perforatum and 36 climatic environmental factors, using the MaxEnt model and GIS technology to explore the main climatic factors affecting the distribution of H. perforatum. Additionally, by utilizing the principles of ecological niche theory, the potential suitable distribution regions of H. perforatum across past, present, and future timelines were predicted, which can ascertain the dynamics of its spatial distribution patterns and the trend of centroid migration. The results indicate that the main environmental factors affecting the geographical distribution of H. perforatum are solar radiation in April (Srad4), solar radiation in September (Srad9), mean temperature of driest quarter (Bio9), solar radiation in November (Srad11), annual mean temperature (Bio1), and annual precipitation (Bio12). Under future climate scenarios, there is a remarkable trend of expansion in the suitable distribution areas of H. perforatum. The centroid migration indicates a trend of migration towards the northwest direction and high-altitude areas. These results can provide a scientific basis for formulating conservation and sustainable use management strategies for H. perforatum resources.

Organic carbon in Mollisols of the world − A review

Mollisols represent 29 % of agricultural land and they are considered to be one of the most fertile soils in the world. Here, we compare soil organic carbon (SOC) concentrations and pools of Mollisols for the globe, the USA and Poland, and review how differences are caused by climate, land use, and key environmental factors. Globally, the mean thickness of the A horizon in Mollisols is 50 cm. At 0–30 cm the mean SOC concentration is 2.3 %, SOC pool is 84 t ha−1, and clay content calculated at 0–50 cm soil depth is 21 %. Mollisols in the USA have an A horizon thickness of 36 cm and have a mean clay content of 27 % (0–50 cm). SOC concentrations are 2.0 and 1.7 % and SOC pools are 85 and 116 t ha−1 at 0–30 and 0–50 cm soil depth, respectively. Mollisols in Poland have SOC concentrations of 1.8 and 1.5 % at 0–30 and 0–50 cm soil depth, respectively, and lower clay content (17 %) at 0–50 cm depth. The SOC pool at 0–30 cm depth is 74 t ha−1 whereas it is 106 t ha−1 at 0–50 cm. At the global scale, the highest SOC concentrations and pools are in Mollisols from Eastern Europe (including Ukraine and Western Russia) and Asia, while the lowest SOC pools are found in Mollisols from South America. The Mollisols in Western and Central Europe and North America have similar SOC pools, although Mollisols in North America have higher SOC concentrations and lower A horizon thickness. Globally, the mean pH value of Mollisols is 7.1, and the pH is slightly lower in Mollisols of the USA (6.9 ± 0.9). The SOC concentrations and pools are strongly and positively correlated with clay content. Soil moisture and temperature regimes determine SOC concentration and pools in Mollisols, and higher SOC concentrations and pools are in Mollisols with frigid and frigid-cryic soil temperature regimes as well as aquic, xeric, and aridic soil moisture regimes. Mollisols under grassland have the largest SOC pools compared to those cultivated or under forest. The important environmental factors on SOC concentrations and pools in Mollisols worldwide are soil texture, land use, and soil temperature regime.

Predicting the Impact of Climate Change on the Future Distribution of Paederus fuscipes Curtis, 1826, in China Based on the MaxEnt Model.

Paederus fuscipes Curtis, 1826, belongs to the Coleoptera order, Staphylinidae family, and Paederus genus (Fabricius, 1775). It has a wide distribution and strong invasive and environmental adaptation capabilities. As a predatory natural enemy of agricultural and forestry pests, understanding its suitable habitat is crucial for the control of other pests. This study, for the first time, uses the MaxEnt model and ArcGIS software, combining known distribution information of P. fuscipes and climate environmental factors to predict the current and future suitable habitat distribution of this insect. The key environmental variables affecting the distribution of P. fuscipes have been identified as mean diurnal range (mean of monthly (max temp-min temp)) (bio2), isothermality (Bio2/Bio7) (*100) (bio3), minimum temperature of the coldest month (bio6), temperature annual range (bio5-bio6) (bio7), mean temperature of the driest quarter (bio9), mean temperature of the coldest quarter (bio11), precipitation of the wettest month (bio13), precipitation of the driest month (bio14), and precipitation seasonality (coefficient of variation) (bio15). The highly suitable areas for P. fuscipes in China are mainly distributed in the hilly regions of Shandong, the North China Plain, and the middle and lower reaches of the Yangtze River Plain, with a total suitable area of 118.96 × 104 km2, accounting for 12.35% of China's total area. According to future climate change scenarios, it is predicted that the area of highly and lowly suitable regions will significantly decrease, while moderately suitable regions will increase (except for the 2090s, SSP2-4.5 scenario). These research findings provide important theoretical support for pest control and ecological conservation applications.

Climate factors associated with cancer incidence: An ecological study covering 33 cancers from population-based registries in 37 countries

Cancer etiology is multifactorial, with climate change and environmental factors such as extreme weather events and ozone layer destruction potentially increasing cancer risk. Investigating climate factors with cancer incidence can provide valuable insights for prevention and future disease burden prediction. We conducted a population-based ecological study using data from the World Health Organization’s Cancer Incidence in Five Continents (CI5plus, 89 cancer registries from 1998 to 2012) and the Surveillance, Epidemiology, and End Results (SEER, 607 US counties from 2000 to 2018) Program. We tracked climate factors through satellite-based remote sensing, including green space, stratospheric ozone concentration, solar radiation, precipitation, and temperature. We performed linear panel regression models to estimate the effects of both long-term exposure, lag effect, and change rate of climate factors on cancer incidences. We adjusted for smoking prevalence, air pollution, and gross domestic product (GDP) per capita to account for potential confounding factors. Our study included more than 430 million underlying populations across 37 countries. Higher green space exposure (per 0.1-unit normalized difference vegetation index, NDVI) was associated with decreased incidence of lung cancer (up to 6.66 cases [95%CI 4.38–8.93] per 100,000) and prostate cancer (up to 10.84 cases [95% CI 7.73–13.95] per 100,000). Increased solar radiation was associated with a higher incidence of melanoma, but a lower incidence of prostate cancer. No evidence was found to suggest associations between temperature or precipitation and cancer incidence. However, a rapid increase in temperature was linked to higher incidences of corpus uteri cancer and melanoma. Long-term exposure and rapid changes in climate factors may influence changes in cancer incidence, particularly lung and prostate cancers. While some associations were supported by existing evidence (such as solar radiation and melanoma), further research is necessary to investigate the etiology of novel cancer risk factors.
