Corporate uncertainty perception, innovation resilience and environmental performance: evidence from Chinese listed companies

ABSTRACT The twin crises of growing global environmental problems and frequent economic policy uncertainty have received widespread attention. However, the existing literature is limited to the impact of uncertainty on corporate environmental protection at the macro level and remains controversial. Based on the subjective perception perspective of firms, this paper explores the impact of corporate uncertainty perception on corporate environmental performance (EP) and the role of innovation resilience as a mechanism in it, using data from Chinese listed companies between 2007 and 2018. The study finds that uncertainty perception positively affects EP, which remains consistent even after conducting endogeneity and robustness tests. Heterogeneity tests reveal uncertainty perception’s stronger positive impact on EP among firms in eastern and central provinces, in maturity or decline stages, and with a focus on capital or technology. The mechanism analysis reveals that innovation resilience plays a positive moderating role in the relationship between uncertainty perception and EP. This paper addresses the controversy over the relationship between uncertainty and EP from corporate subjective perception perspective, improves the innovation resilience measure, enriches the mechanism of uncertainty perception’s role on EP, and expands the scope of application for strategic growth theory and resilience theory in organizational management.

The Relationship Between Air Pollution Components and Hospitalizations Due to Acute Pulmonary Embolism

Objectives: This study was conducted to examine the relationship between air pollution and pulmonary embolism in patients hospitalized in Urmia city. This cross-sectional study was conducted in West Azerbaijan province, Iran. According to the daily report from the meteorology center of West Azarbaijan province, the data on the concentrations of air pollutants, including PM10, NO2, O3, CO, and PM2.5 were extracted. Moreover, the files of patients without underlying risk factors hospitalized due to pulmonary embolism were extracted. Finally, admissions from 2 days before until 2 days after the polluted days were compared to hospitalizations on clean air days of the same month. Design: A cross-sectional study. Setting(s): Urmia, the capital city of the West Azerbaijan province in northwestern Iran. Participants: A total of 1275 patients without underlying risk factors hospitalized due to pulmonary embolism were included. Outcome measures: Admissions from 2 days before until 2 days after the polluted days were compared to hospitalizations on clean air days of the same month. Results: Out of 1779 patients admitted due to pulmonary embolism, 1275 patients met our inclusion and exclusion criteria. Based on the results, 403 patients (31.6%) were hospitalized in clean and healthy air (air quality index [AQI] of 0-50 and 50-100), 816 patients (64.1%) were hospitalized in unhealthy air (AQI: 150-101), and 56 patients (4.4%) were hospitalized in days with polluted air (AQI:151-200). According to Pearson’s correlation coefficient, there was a significant relationship between carbon monoxide (r=0.09, P=0.0001), sulfur dioxide (r=0.11, P=0.001), PM10 (r=0.28, P=0.001), and PM2.5 (r=0.45, P=0.0001) concentrations and the frequency of hospitalizations due to pulmonary embolism. Conclusions: There is a positive and significant relationship between air pollutants and the number of hospitalizations due to pulmonary embolism. Hence, preventive measures should be taken into account regarding the air pollution at the provincial and national levels.

The district Toba Tek Singh is located in the center of Punjab province. It occupies 2nd important position in national citrus production after Sargodha, with citrus orchard area of 11412 hectares and annual production of 160758 tons. Citrus productivity in Pakistan, in general, and Toba Tek Singh, in particular, is far below its its potential which could be attributed to several factors but poor soil health and inadequate soil fertility may be considered an important reason. A comprehensive nutrient indexing survey of thirty citrus orchards grown in different parts of district Toba Tek Singh was conducted to evaluate the soil characteristics and plant nutrient status. GPS coordinates of selected sites were recorded prior to sampling. Soil samples were collected at 0-20 cm, 21-40 cm and 41-60 cm depth using standard procedure. Five soil samples were collected from each site to get a composite sample for each depth. The leaf samples were collected from the 7-month-old non-fruiting branches of plants around the tree canopy during the month of September, 2022. Five healthy and uniform citrus trees were sampled from each site to get a composite leaf sample. The soil samples were analyzed for pH, electrical conductivity (EC), soil organic matter (SOM) and calcium carbonate (CaCO3). The soil and leaf samples were analyzed for macro and micronutrients. It was found that most of orchard soils of district Toba Tek Singh were moderately alkaline (pH 7.52-8.90), slight to strong calcareous (2-15% CaCO3), non-saline (0.77-3.0 dS m-1 EC) and low in SOM (0.23-1.49%) with low to medium nitrogen (0.01-0.06%) and phosphorus (0.58-10.52 mg kg-1) while medium to high potassium (56.47-315.34 mg kg-1). The sampled soils were low to marginal in boron (0.09-0.72 mg kg-1), copper (0.05-0.59 mg kg-1), iron (0.23-10.75 mg kg-1) and zinc (0.03-1.83 mg kg-1) while adequate in manganese (1.35-26.20 mg kg-1). Leaf analysis revealed that almost 50% orchards were deficient in phosphorus (0.05-0.23%) and potassium (0.40-1.76%), while having low to marginal values of copper (1.96-20.99 mg kg-1), zinc (4.13-31.96 mg kg-1), boron (3.12-95.40 mg kg-1), manganese (42.62-96.46 mg kg-1) but adequate iron (171-552 mg kg-1). The surveyed orchard soils were mostly alkaline calcareous, deficient in organic matter and having low to moderate macro and micronutrients.

Time trends and disparities of obesity and related national policies and programs in Nepal: a systematic review

ObjectiveOverweight and obesity prevalence has increased in low-income countries. This study systematically reviewed the obesity trend, disparities, and prevention and control efforts in Nepal. MethodsWe searched PubMed and Google Scholar for articles and reports published between January 1, 2004 and December 31, 2022. Additional information on National policies and programs related to obesity prevention was retrieved from governmental websites and consultation with relevant experts. Overweight and obesity were defined using the World Health Organization body mass index cut points. Thirty-two studies and reports were included. ResultsOverall, overweight and obesity rates increased in all groups in Nepal although nationally representative data remained limited. The combined overweight and obesity (OW/OB) and obesity rates in women aged 15‒49 years increased from 8.5% to 22.2% and from 0.9% to 5.1% between 2006 and 2016, respectively. OW/OB and obesity rates in men were 17.1% and 2.5% based on data from the 2016 Demographic and Health Survey. OW/OB rate in under-five children increased from 0.6% to 2.8% between 2006 and 2016. Obesity rates for school-age (5‒9 years) boys and girls in 2016 were 2.4% and 2.8%, respectively, and were 1.1% and 1.4% for male and female adolescents aged 10‒19 years, respectively. OW/OB prevalence was much higher among women, residents in urban areas and central provinces, and in higher socioeconomic status groups. Projected prevalence of OW/OB and obesity for 2030 in adults aged 15‒49 was 44.7% and 8.3%, respectively, while it was 2.2% for OW/OB in preschool children. Policies and direct interventions that specifically focused on obesity prevention and control are limited. ConclusionsOW/OB prevalence in Nepal has increased during the past 1.8 decades, disproportionately affecting population groups. Existing interventions mostly focused on undernutrition with some indirect implications for obesity prevention. In the future, Nepal needs to develop population-based programs for obesity prevention.

Health-related quality of life among Moroccan women after vaginal birth and cesarean section: Cross-sectional study

BackgroundDuring the postpartum period, understanding women's well-being, specifically their Health-related Quality of Life (HRQoL), is vital for comprehensive healthcare. ObjectivesOur study aims to explore the HRQoL and its associated factors in Moroccan women after vaginal birth (VB) and cesarean section (CS). Study designIn this cross-sectional study we assessed the HRQoL and its associated factors among Moroccan women who gave birth at the provincial hospital center of Settat. We gathered data from 566 women, using the EQ-5D-5L instrument alongside questionnaires about socioeconomic and obstetrical aspects. The assessment was conducted utilizing the improved Relative to an Identified Distribution (RIDIT) approach, and we employed a multiple linear regression model to pinpoint the associated factors. ResultsA total of 566 women were included in our study. Our results revealed that the HRQoL in women who underwent CS was significantly lower than in VB women (EQ-5D index score = 0.30 ± 0.28 vs 0.61 ± 0.31; p < 0.0001). Similarly, the CS reduced the EQ-VAS score (mean difference = −10.73 ± 3.78; p < 0.0001). The CS was associated negatively with problems in mobility (ARI = 55 % [42–67], p < 0.0001), autonomy (ARI = 67 % [57–80], p < 0.0001), and usual activities (ARI = 56 % [42–69], p < 0.0001). Also, CS was associated with pain/discomfort (ARI = 47 % [34–60], p < 0.0001) and anxiety/depression (ARI = 3 % [-5.8-12.6], p = 0.31). The women who had birth complications had the worst HRQoL (EQ-5D index score = 0.32) compared to those who had no complications (EQ-5D index score = 0.56). Likewise, women who had postpartum complications had the worst HRQoL (EQ-5D index score = 0.39 vs EQ-5D index score = 0.54). ConclusionThe results highlighted that mode of birth, childbirth complications, and postpartum complications are strongly associated with women's HRQoL. The EQ-5D-5L dimensions were affected after delivery. Hence, there is a requirement to create specialized initiatives for overseeing postpartum HRQoL, aiming to enhance the quality of maternal healthcare.

Distributional effects of expressway access on rural entrepreneurial activities in China

Transportation infrastructure development, such as expressways, could impact economic development in local and neighboring regions differently. However, there is limited evidence of these impacts on rural and developing areas. Here, we use Heyuan, a rural region in China, as the case to examine the effects of expressway access on entrepreneurial activity. Using detailed township-level panel data from 2004 to 2016 and a multiple-period DID model with spatial effects, we find that opening entrances and exits significantly promotes entrepreneurial activities in local towns but suppress them in adjacent towns. Furthermore, we find that the development of expressways leads to a greater concentration of firms in the provincial centers of towns with better economic development. The development of expressways has had a significant boost on tertiary industries. This study shows that the construction of highways attracts entrepreneurial activities to regions with better conditions, and this maximizes economic efficiency but at the expense of creating regional economic imbalances. Therefore, this model may be the primary model of China's economic development in the future.

Implementation of the Sakti application (agency-level financial application system) in Government financial management at the statistical center of Gorontalo province

The purpose of this research is to identify the application and constraints of the application of SAKTI application in government financial management at BPS Gorontalo Province. The research data was collected through observation, interviews, and documentation. The results showed that BPS Gorontalo Province has implemented the use of the SAKTI application and has been running since the application launch was carried out on January 2, 2022. Judging from the organizational readiness, interpretation, and application have not run optimally. This is because there are factors that affect the implementation of the use of the SAKTI application in state financial management at BPS Gorontalo Province, including a rather complicated operating process (there are many stages), inadequate human resources in terms of numbers, there are even employees who hold concurrent positions, and information technology facilities and infrastructure in supporting the application implementation are quite adequate, but the obstacles that users often face are from the application itself, which quite often experiences server downtime.

The relationship between spiritual health and quality of life among COVID-19 patients with long-term complications in the post-coronavirus era.

COVID-19 has varied manifestations and can cause complications that affect quality of life. Spiritual health may be a source of adaptation for these patients. This study investigated the relationship between spiritual health and quality of life among COVID-19 patients with long-term complications in the post-coronavirus era. This study enrolled 475 COVID-19 patients through convenience sampling from medical facilities located in the Central Province of Iran. Data collection occurred between November 2022 and July 2023. A demographic checklist was utilized to ascertain the presence of potential COVID-19 complications. Patients exhibiting at least one long-term complication of COVID-19 were classified into the group with complications, while those without such complications were categorized into the group without complications. Subsequently, spiritual health and quality of life were assessed utilizing Paloutzian and Ellison's Spiritual Well-Being Scale and the 36-item Short Form Health Survey (SF-36), respectively. Statistical analysis was conducted using SPSS-20. The mean scores of spiritual well-being and quality of life for participants without COVID-19 complications were 70.87 ± 22.44 and 61.30 ± 18.33, respectively. In contrast, the mean spiritual health scores and quality of life for participants with COVID-19 complications were 41.20 ± 12.49 and 33.66 ± 1.46, respectively. Moreover, spiritual well-being was positively associated with quality of life among COVID-19 patients (p < 0.05). This study indicates that COVID-19 complications can impair patients' spiritual health and quality of life, leaving them vulnerable and distressed. However, patients with higher spiritual health can cope better and enjoy a higher quality of life, despite challenges. Therefore, this study highlights the importance of addressing the spiritual needs of patients with COVID-19 complications and providing them with adequate support and care.

Finding boundaries in the sea: The Main and Small Gap of the Emperor Seamount Chain as a biogeographic boundary for bathyal benthic fauna

Studies on the bathyal fauna of northern Pacific waters suggested that a transition or boundary between the North Pacific Province and Central Pacific Provinces would be found somewhere along the Emperor Seamount Chain. Strong currents flow west to east across the seamount chain in a region known as the Main Gap and it was proposed that any larvae produced either north or south of the Main Gap would not be capable of crossing the gap. An expedition to test the hypothesis that a faunal change would be found in the vicinity of the Main Gap was conducted in 2019. Eleven ROV dives were conducted, one on an unnamed seamount at the southern edge of Hess Rise, and 10 dives on seven seamounts along the Emperor Seamount Chain. Six dives were on seamounts north of the Main Gap, while four (including the dive on Hess Rise) were on the southern side. Of the six northern dives, three were at deeper depths (∼2000–1800 m) and three were shallower (∼1500–1100 m); of the southern dives two were at the deeper depths and two were shallower. One shallower dive occurred on Jingu Seamount, situated on the southern edge of the Main Gap. Analysis of the fauna from both collected specimens and annotations of the dive video produced four clusters: a, the four dives south of the Main Gap; b, the three deeper dives north of the Main Gap; c, the shallower dive at Jingu Seamount; and d, the four shallower bathyal dives north of the Main Gap. It was concluded that the bathyal fauna underwent a significant change from north to south across the area of the Main Gap and the adjacent Small Gap, in the area of 37–39 °N, covering distances as small as 75 km or as much as 400 km.

TBE In Italy

Italy is considered a low-incidence country for tick-borne encephalitis (TBE) in Europe.1 Areas at higher risk for TBE within Italy are geographically clustered in the forested and mountainous regions and provinces of the northeastern part of the country, as suggested by TBE case series published over the last decade. 2–4 A national enhanced surveillance system for TBE has been established since 2017.5 Before this, information on the occurrence of TBE cases at the national level in Italy was lacking. Both incidence rates and the geographical distribution of the disease were mostly inferred from endemic areas where surveillance was already in place, and from ad hoc studies and international literature. TBE has been recorded in Italy since 1967, with foci of infections in the northeast (Trento, Belluno and Gorizia) and central (Florence and Latina) provinces.6–9 TBE presence in central Italy has not been confirmed by further studies on ticks and serosurveys conducted afterwards,10,11 nor by human cases, posing concerns about possible misdiagnosis.

Late Triassic to Early Jurassic carbon isotope chemostratigraphy and organo-facies evolution in a distal to proximal transect of the North German Basin

AbstractThroughout the Latest Triassic and the Early Jurassic, major changes in paleogeography, climate and eustatic sea-level impacted on the development of shelf depositional environments. Secular trends in environmental conditions were punctuated by transient perturbations that occurred in relation to large-scale volcanic events, such as the emplacement of the Central Atlantic Magmatic Province at the Triassic/Jurassic boundary and the Karoo–Ferrar Large Igneous Province in the early Toarcian. We here present bulk organic (HAWK programmed pyrolysis) and organic carbon isotope (δ13Corg) data for three drill cores recovering Latest Triassic and Early Jurassic strata (Rhaetian to Toarcian). Study sites are located in the northeastern part of the Central European Epicontinental Sea and were positioned along a distal–proximal transect of the North German Basin. This allows discussing the differential response of depositional settings and organo-facies toward secular and transient environmental change. Biostratigraphically anchored trends in δ13Corg values allow the precise correlation along the transect, as well as with distant sites. At all North German locations, diagnostic secular trends in δ13Corg are punctuated by transient negative carbon isotope excursions, reflecting perturbations of the global carbon cycle at the Triassic/Jurassic boundary and in the early Toarcian. Stratigraphic gaps occurred during sea-level lowstands and are most pronounced at shallow proximal sites. Programmed pyrolysis data indicate spatiotemporal organo-facies trends that on a temporal scale occurred in response to sea-level and climate trends, while spatial patterns were governed by basin morphology and paleobathymetry. Substantial marine organic matter accumulations occurred at high sea level during the Toarcian only, and were most continuous at distal sites. Graphical Abstract

MINERALOGICAL AND PHYSICO-CHEMICAL CHARACTERISATION OF CLAY MATERIALS FROM KWILU-NGONGO (Kongo-Central, DR Congo)

Clay materials collected from two sites (Camp-Beton and Kwilu-Bricks) in the Kwilu-Ngongo region located between 5°30’0’’S and 14°40’60’’E, in the Kongo Central province (DRC), Ten samples selected and subjected to mineralogical, physico-chemical and geotechnical studies with a view to their characterization. Mineralogical analysis by X-ray diffraction made it possible to identify the following minerals: quartz, feldpasth, iron oxide and simple clay minerals including kaolinite. In addition to this kaolinite we also find illite, chlorite and vermiculite. The partical size analysis led to the differentiation of three fractions including: the fine clay fraction, the silty fraction and the sandy fraction. As for the Atterberg Limits, the plasticity Limit ranges from 17 to 30% while the average plasticity index is 13 %. Chemical analyzes made it possible to identify the major oxides elements below: SiO2, Al2O3, TiO2, Fe2O3, K2O, Na2O and MgO.

AN ASSESSMENT OF PESTICIDE POISONING INCIDENCES PRESENTED AT HEALTH CARE FACILITIES IN MASHONALAND CENTRAL PROVINCE, ZIMBABWE

Acute Pesticide Poisoning (APP) is a significant problem in developing countries, causing loss of productivity and fatalities in the agricultural sector. However, limited information on the connection between pesticide use, APP, and deaths in Zimbabwe is available. This study aimed to evaluate incidents that resulted in APP and identify the specific pesticides that caused them at Health Care Facilities (HCFs) in Mashonaland Central Province. Researchers conducted a survey asking standardized questions to gather information on APP cases from 93 HCFs. Descriptive statistics and chi-square association tests for APP cases in the targeted HCFs were calculated using IBM SPSS version 22. The study found that 43% of APP cases were due to pesticides belonging to the World Health Organization (WHO) class II acute toxicity category, while 26.1% were caused by Highly Hazardous Pesticides (HHPs). Most of the cases were due to intentional poisoning (87.1%), with the majority (55.9%) of APP incidents being males. The highest APP cases were recorded in the 21-30 age group (38.8%), followed by the 31-40 age group (32.8%). These results emphasize the significant impact of intentional poisoning by WHO class II type pesticides, particularly HHPs, on the incidence of APP in Zimbabwe. To mitigate the impact of HHPs on human health, it is recommended that the government of Zimbabwe consider pesticide risk reduction measures, such as stricter pesticide registration criteria, import restrictions, and the promotion of less toxic alternatives. These findings highlight the urgent need for policymakers, researchers, and other stakeholders in the agricultural sector to work collaboratively towards creating a safer and more sustainable farming environment in Zimbabwe.

Health service use in major trauma survivors: A population-based cohort study from Ontario, Canada.

Little is known about how major trauma survivors access health services in the years following their injury. Our study sought to characterize patterns of health services use in trauma survivors following discharge from a provincial trauma center and to identify sociodemographic factors associated with service utilization. We conducted a population-based retrospective case-control study using linked administrative data on trauma survivors' population-based controls between April 1, 2011, and March 31, 2021. For each major trauma survivor, we matched four cases based on age and sex. The primary outcome was the composite rate (sum) of health service use episodes including outpatient visits to family physicians and specialists, emergency department visits, and acute care hospital admissions during the 5-year period following discharge from the trauma center. We used multivariate regression to compute rate ratios comparing the rates of health service use in trauma survivors versus controls and to assess for associations between sociodemographic variables and health services use. The study cohort consisted of a total of 273,406 individuals: 55,060 trauma survivors and 218,346 controls. Trauma survivors were predominately males (71%) with a median age of 46 years (interquartile range, 26-65 years). Health service use in trauma survivors peaked within a year of hospital discharge but remained increased throughout the follow-up period. Trauma survivorship was associated with a 56% increase in overall health services use (adjusted rate ratio, 1.56; 95% confidence interval, 1.55-1.57), including an 88% increase in hospital admissions (adjusted rate ratio, 1.88; 95% confidence interval, 1.85-1.92). Male sex and rural residence were associated with a reduced overall use of health services but greater use of emergency department services. Major trauma survivors have long-term health services needs that persist for years after discharge from the trauma center. Future research should focus on the understanding why trauma survivors have prolonged health services requirements and ensure that care needs are aligned with service delivery.

Petrogenesis of volcanic rocks from the Quaternary Eifel volcanic fields, Germany: detailed insights from combined trace-element and Sr–Nd–Hf–Pb–Os isotope data

Quaternary rocks from the East and West Eifel volcanic fields in western Germany are a key suite of intraplate volcanic rocks that can provide insights into volcanism of the Central European Volcanic Province (CEVP) and into continental intraplate volcanism in general. We present a comprehensive dataset for Eifel lavas including isotope as well as major and trace element data for 59 samples covering representative compositions of the different volcanic fields. In line with previous studies, the lavas are all SiO2-undersaturated, alkaline-rich and mainly comprise primitive basanites, melilitites, and nephelinites (Mg# ≥ 57). Geochemical compositions of samples from both volcanic subfields display distinct differences in their trace-element as well as radiogenic isotope compositions, largely confirming previous subdivisions. Coupled trace-element and radiogenic Sr–Nd–Hf–Pb–Os isotope compositions can now provide firm evidence for spatially heterogeneous mantle sources and compositionally distinct magmatic pulses. Within the West Eifel Field, Sr–Nd–Pb isotope compositions of the younger (≤80 ka), ONB-suite (olivine-nephelinite-basanite) are similar to FOZO (FOcal ZOne) or the EAR (European Asthenospheric Reservoir) and resemble compositions that have been previously reported from plume-sourced ocean island basalts (OIB). In marked difference, older (700 Ma to 80 ka) volcanic rocks from the F-suite (Foidite) in the West Eifel field and from the entire east Eifel Field tap a more enriched mantle component, as illustrated by more radiogenic Sr isotope (86Sr/87Sr up to 0.705408) and variable Pb isotope compositions (206Pb/204Pb = 18.61–19.70, 207Pb/204Pb = 15.62–15.67 and 208Pb/204Pb = 38.89–39.76). Combined trace-element compositions of ONB-suite samples are in good agreement with results from batch melting models suggesting a hybrid composition of Eifel magmas formed through mixing 10% of a FOZO-like melt with 90% of a DMM-like melt, similar to melts from the Tertiary HEVF. However, radiogenic Sr–Nd–Pb isotope compositions of F-suite and EEVF and some ONB lavas require the admixture of melts from lithospheric mantle sources. Elevated Nb/Ta and Lu/Hf ratios in combination with variable 187Os/188Os ratios can now demonstrate the presence of residual carbonated eclogite components, either in the lithosphere or in the asthenospheric mantle. Finally, by combining geochemical and temporal constraints of Tertiary and Quaternary volcanism it becomes evident that CEVP volcanism in central and western Germany has resulted from compositionally distinct magmatic pulses that tap separate mantle sources. Although the presence of a mantle plume can neither be fully confirmed nor excluded, plume-like melt pulses which partially tap carbonated eclogite domains that interact to variable extents with the lithosphere provide a viable explanation for the temporal and compositional cyclicity of CEVP volcanism.

The Natural State of Gardez City

The present research has been investigated in relation to (the natural state of Gardez city, the center of Paktia province), which was used in the form of quantitative and qualitative research in the year 2021 in the Department of Geography. The city of Gardez is one of the highest centers of the provinces of Afghanistan, whose average height is 2,350 meters, after the center of Bamyan province, whose height is 2,550 above sea level. Therefore, Gardez is the second highest among all the centers in the provinces of Afghanistan. The existence of heights, low points and mountains around Gardez, such as Sulaiman Ghar and Spin Ghar Mountains, has affected the climate of this region. Gardez has an area of about (750) square kilometers. In terms of elevations and lowlands, Gardez can be divided into three parts: mountains, mountain slopes and low-altitude areas, and its famous mountains are Spin Ghar and Suleiman Ghar and other mountains around Gardez called. The local areas are mentioned; it consists of Spin Ghar and Suleiman Ghar Mountains, all these mountains contain 244, 3518 hectares of land in Gardez. Generally, in Gardez, the slopes of these mountains form grassland areas and the low areas are land. Agricultural areas, residential areas, urban areas and government facilities. The Gardez Sea continues its path from the northeast to the southwest of Gardez and has water in the winter and spring seasons, and at the end, after travelling 110 kilometers, the Gardez Sea passes through the Sardah Dam in Ghazni province and stands in the water. The seat falls.

Staphylococcus warneri, an unconventional plant pathogen involved in canker disease of almond and other Prunus species

AbstractBacterial canker disease of stone fruits is a major concern in stone fruit‐growing countries worldwide. Pseudomonas spp. and Xanthomonas arboricola pv. pruni (Xap) are the primary pathogens involved in this disease. In spring, summer and autumn 2016, symptoms like those produced by Pseudomonas spp. and Xap were observed in almond, apricot, peach and nectarine orchards in central provinces of Iran (Qom, Isfahan, and Chaharmahal and Bakhtiari). Gram‐positive cocci bacterial isolates were obtained from symptomatic trees. Following hypersensitivity and pathogenicity tests, isolates were divided into pathogenic and nonpathogenic groups, demonstrating the pathogenicity of some isolates on saplings of almond, peach and apricot. Multilocus sequence analysis was performed using the partial sequence of 16S rRNA region and four housekeeping genes, namely tuf, gap, dnaJ and rpoB, to determine the taxonomic classification of isolates, and revealed that pathogenic isolates identified as Staphylococcus warneri, while nonpathogenic isolates identified as S. warneri, S. epidermidis, S. hominis and S. saprophyticus. The isolates were further characterized by phenotypic and biochemical tests as well as by antibiotics assays. The unusual nature of the identified microorganism in the present study lies in the fact that, unlike most plant‐pathogenic agents, S. warneri is recognized worldwide as a cause of bacterial infections in humans and animals. Taken together, the bacterial canker disease caused by S. warneri appears to be a newly emerging disease of apricot, peach and almond trees.

Prediction of Potential Suitable Distribution Areas for an Endangered Salamander in China.

Climate change has been considered to pose critical threats for wildlife. During the past decade, species distribution models were widely used to assess the effects of climate change on the distribution of species' suitable habitats. Among all the vertebrates, amphibians are most vulnerable to climate change. This is especially true for salamanders, which possess some specific traits such as cutaneous respiration and low vagility. The Wushan salamander (Liua shihi) is a threatened and protected salamander in China, with its wild population decreasing continuously. The main objective of this study was to predict the distribution of suitable habitat for L. shihi using the ENMeval parameter-optimized MaxEnt model under current and future climate conditions. Our results showed that precipitation, cloud density, vegetation type, and ultraviolet radiation were the main environmental factors affecting the distribution of L. shihi. Currently, the suitable habitats for L. shihi are mainly concentrated in the Daba Mountains, including northeastern Chongqing and western Hubei Provinces. Under the future climate conditions, the area of suitable habitats increased, which mainly occurred in central Guizhou Province. This study provided important information for the conservation of L. shihi. Future studies can incorporate more species distribution models to better understand the effects of climate change on the distribution of L. shihi.
