IMPACTS OF CLIMATE CHANGE ON LIVESTOCK HEALTH AND WELFARE IN NIGERIA'S NORTH-EAST REGION

This paper studies the influence of climate change on health and welfare in Nigerian North-East livestock, covering direct and indirect impacts. An increased temperature, changing patterns of precipitation, and an increased humidity culminate into heat stress affecting the physiology, behaviour, and productivity of the livestock.Long-term exposure to extreme heat reduces feed intake, reproductive performance, and immune function due to metabolic disorders, oxidative stress, and increased vulnerability to diseases. Besides, climatic changes favored the dissemination of vector-borne diseases, such as trypanosomiasis and Rift Valley fever, further compromising the health status of livestock and creating zoonotic risks in humans.It also cites nutritional problems caused by higher fungal proliferation caused by climate and leading to mycotoxicoses in feeds. Such changes add pressure on the livelihoods of those depending on the livestock, especially small-scale farmers, who incur enhanced veterinary costs and mortality hence reducing food security.The impact is deep at the socio-economic level, as livestock farming is one of the most important sources of income and sustenance in the region. Thus, the paper calls for a multidimensional adaptive approach through improvements in the management of livestock, nutritional interventions, vector control, and disease surveillance systems to mitigate such challenges. This therefore further underlines the importance of policy development and community involvement in creating resilience and thus assuring a sustainable livestock farming system in the face of a changing climate. It is expected that these findings will inform policy, researchers, and other stakeholders on how to build adaptive capacity within the livestock sector in order to secure livelihoods and improve food security in Northeast Nigeria.

Online Algorithms for Matching Platforms with Multichannel Traffic

Two-sided platforms rely on their recommendation algorithms to help visitors successfully find a match. However, on platforms such as VolunteerMatch, which has facilitated millions of connections between volunteers and nonprofits, a sizable fraction of website traffic arrives directly to a nonprofit’s volunteering page via an external link, thus bypassing the platform’s recommendation algorithm. We study how such platforms should account for this external traffic in the design of their recommendation algorithms, given the goal of maximizing successful matches. We model the platform’s problem as a special case of online matching, where (using VolunteerMatch terminology) volunteers arrive sequentially and probabilistically match with one opportunity, each of which has a finite need for volunteers. In our framework, external traffic is interested only in their targeted opportunity; by contrast, internal traffic may be interested in many opportunities, and the platform’s online algorithm selects which opportunity to recommend. In evaluating the performance of different algorithms, we refine the notion of competitive ratio by parameterizing it based on the amount of external traffic. After demonstrating the shortcomings of a commonly used algorithm that is optimal in the absence of external traffic, we propose a new algorithm, adaptive capacity (AC), which accounts for matches differently based on whether they originate from internal or external traffic. We provide a lower bound on AC’s competitive ratio that is increasing in the amount of external traffic and that is close to (and, in some regimes, exactly matches) the parameterized upper bound we establish on the competitive ratio of any online algorithm. We complement our theoretical results with a numerical study motivated by VolunteerMatch data where we demonstrate the strong performance of AC relative to current practice and further our understanding of the difference between AC and other commonly used algorithms.

An Analyze of the Relationship Between Students’ Motivation, Self-efficacy, and Academic Resilience

Academic resilience represents a critical variable in educational success, reflecting students’ ability to adapt and thrive in the face of academic challenges. Numerous studies have addressed the issue of academic resilience, as understanding the mechanisms underlying academic resilience as essential for the development of effective interventions to support students. Academic resilience is a multifactorial construct, influenced by personal, social and contextual factors, which needs a complex approach. Being an essential competence for the entire life, the academic environment provides the fertile ground for its development. The present research investigates the extent to which perceived self-efficacy and motivation - both intrinsic and extrinsic - impact students’ academic resilience. The study aims to explore how those psychological constructs interact to support adaptive responses in demanding academic environments. A structural equation model was developed and tested on a sample of university students. The findings reveal that academic self-efficacy and intrinsic motivation has a significant and direct positive effect on academic resilience. At the same time, even extrinsic motivation seems to influence negatively the academic resilience, it resulted that it has no direct significant influence on academic resilience. The results underscore the importance of fostering self-efficacy and intrinsic motivation in educational settings, offering critical psycho-pedagogical insights for enhancing students’ adaptive capacities.

Macro- and microscopic anatomy of the digestive tract in the red-eared slider (Emydidae: Trachemys scripta elegans).

The red-eared sliders (Emydidae: Trachemys scripta) is characterised by a high adaptability to a variety of environment and threatens the habitat of Japanese native species. The ability to digest a variety of diets may attribute to the high adaptive capacity of this species to various environments, however, the digestive morphology remains scarcely described in red-eared sliders. In this study, we investigated the macro- and microscopic anatomy of the esophagus, stomach, small intestine, and large intestine in red-eared sliders. All segments of the digestive tract had longitudinal mucosal folds, the height and width of which varied in each segment of the digestive tract. The stomach had the highest and widest mucosal folds. The mucosal folds in the proximal-to-middle small intestine exhibited a zigzag shape, whereas those in the distal small intestine were linear. The wall of the digestive tract regularly consisted of mucosa, submucosa, tunica muscularis, and tunica adventitia or serosa. In each segment of the digestive tract, the epithelial structure was different. The esophagus and small intestine were lined by the pseudostratified columnar epithelium. In both segments, the basal part of the pseudostratified epithelium included proliferating cell nuclear antigen (PCNA)-positive proliferating cells. The stomach and large intestine were lined by the simple columnar epithelium. In the stomach and large intestine, PCNA-positive proliferating cells were present in the neck of the proper gastric gland and crypt-like structures, respectively. The proper gastric gland was composed of oxynticopeptic and mucous cells. This study revealed the detailed macro- and microscopic anatomy of the digestive tract in red-eared sliders. Overall, our findings may provide an anatomical basis for understanding the relationship between morphology and function in the digestive tract of turtles.

The study was carried out in District Nowshera with the aim of investigating the relationship between situational awareness and flood vulnerability reduction in Nowshera, Pakistan. The study is purely quantitative in nature, and the outcome of the quantitative data was collected from 384 respondents in the study area. Univariate and bivariate analysis methods with indexation have been used for the analysis of data. The findings of the study reveal that heightened situational awareness and risk knowledge substantially enhance flood preparedness, evacuation compliance, and adaptive capacity. The research identifies key contributing factors of situational awareness and risk knowledge, including knowledge about the causes and consequences of floods, awareness of flood-prone areas, structural integrity of buildings, land use planning, capacity building, and robust solid waste and sanitation systems at the community level. The findings established significant associations between these factors and flood vulnerability reduction. The study emphasizes the importance of community engagement, effective governance, and resilience measures in development planning to minimize flood vulnerability. The outcomes inform data-driven flood risk management strategies, underscoring the imperative of integrating situational awareness and risk knowledge to mitigate vulnerability and enhance resilience in susceptible communities like District Nowshera.

Pyroxsulam Resistance in Apera spica-venti: An Emerging Challenge in Crop Protection.

Apera spica-venti, a prevalent weed in Czech winter wheat fields, has developed resistance to ALS-inhibiting herbicides due to their frequent use. This study reports a biotype of A. spica-venti resistant to pyroxsulam, with cross and multiple resistance to iodosulfuron, propoxycarbazone, pinoxaden, and chlortoluron. Dose-response experiments revealed high resistance of both R1 and R2 biotypes to pyroxsulam, with resistance factors (RF) of 6.69 and 141.65, respectively. Pre-treatment with malathion reduced RF by 2.40× and 1.25× in R1 and R2, indicating the potential involvement of cytochrome P450 (CytP450). NBD-Cl pre-treatment decreased RF only in R2, suggesting possible GST involvement. Gene analysis revealed no mutations (at previously reported sites) or overexpression in the acetolactate synthase (ALS) gene. However, a significant difference in ALS enzyme activity between resistant and susceptible biotypes points to target-site resistance mechanisms. Studies with 14C-labeled pyroxsulam showed that reduced absorption and translocation were not likely resistance mechanisms. In summary, herbicide resistance in A. spica-venti appears to result from multiple mechanisms. Possible causes include target-site resistance from an unidentified ALS mutation (within coding or regulatory regions). Enhanced herbicide metabolism via CytP450s and GSTs is also a contributing factor. Further experimental validation is needed to confirm these mechanisms and fully understand the resistance. This evolution underscores the adaptive capacity of weed populations under herbicide pressure, emphasizing the need for alternative control strategies.

Molecular Analysis of the Species Dracocephalum moldavica L.

There is a growing global trend in the consumption of cultivated medicinal and aromatic plants and an increasing demand for medicinal plants for the production of herbal medicines, health products, dietary supplements, and cosmetic products. The raw plant material from medicinal plant crops is insufficient to meet the needs of this industry. There is a preference for cultivated plant material because most pharmaceutical companies prefer raw materials that meet the required quality standards. Therefore, expanding the cultivation of medicinal plant and introducing new species into cultivation is becoming an important objective. These efforts are complemented by other advantages of cultivation (e.g., modern mechanized agricultural techniques, irrigation, fertilization, and mechanized harvesting). Molecular characterization of the species Dracocephalum moldavica, was focused on analysing the genetic structure of a cultivated plant population. Genetic analysis can provide important data regarding intra- and interpopulation genetic polymorphism, closely correlated with the adaptive capacity of the species to different pedo-climatic conditions, as well as the biosynthetic capacity of pharmacologically active compounds. This enables the accurate identification and selection of new valuable genotypes. Molecular analysis can be performed using DNA molecular markers, among which SSR (simple sequence repeats) and ISSR (inter simple sequence repeats) markers are frequently used due to their high reproducibility, relatively low cost, and avoidance of radioactivity (as is the case with other molecular markers). In this study, ISSR markers revealed genetic polymorphism of cultivated plants.

Building Community Resilience and Adaptive Capacity Through Investments in Tourism and Conservation

This study applies human ecology theory to examine community resilience and adaptive capacity in a nature-based tourism destination. Data were collected through a survey of 207 residents in Corrientes, Argentina in communities where internationally recognized efforts to drive tourism, protect large landscapes, and restore natural resources have taken place. The results of the analysis revealed six domains of community resilience through a confirmatory factor analysis and illustrated that tourism and conservation investments increase tourism involvement, which leads to direct and indirect paths of increases in community resilience and adaptive capacity. Multivariate relationships were detected between tourism involvement and four of the six identified community resilience domains, and between tourism involvement and adaptive capacity through three community resilience domains acting as mediating variables. Using human ecology theory as a framework, this study provides insights into how communities’ adaptive capacity develops through residents’ engagement in entrepreneurial and self-organization opportunities offered by tourism.

Exploring organizational resilience as a quality indicator in social services: A cross-sectional study

Social Services are vital for addressing adversity and safeguarding vulnerable individuals, presenting professionals with complex challenges that demand resilience, recovery, and continual learning. This study investigates Organizational Resilience within Community Social Services, focusing on strategic planning, adaptive capacity, and user perspectives. A cross-sectional study involved 534 professionals and service users from Community Social Services Centers in Spain. Centers were selected based on the characteristics of their population and the representativeness of their geographic location. The study utilized the Benchmark Resilience Tool (BRT) to evaluate Organizational Resilience and the SERVPERF questionnaire to gauge user-perceived service quality. The results demonstrate satisfactory levels of Organizational Resilience and user satisfaction, while also highlighting key areas for enhancing resilient strategies: reinforcement of personnel for thinking outside the box or in the resources available to the organization to face unexpected changes. These findings suggest the need to develop and optimize measures that improve the organization’s ability to adapt to and recover from adverse situations, ensuring a positive user experience. Emphasizing the importance of resilience in Social Services as a quality predictor, future research should explore innovative strategies to bolster Organizational Resilience. The findings emphasize the need to strengthen resilience in Social Services, enhancing practice, policy, and adaptability to support vulnerable populations.

Impact of Rainfall and Temperature as Aspects of Climate Change on Maize Production in Zimbabwe

Zimbabwe experiences variations in maize production such that production fell below 2.2 million tonnes between 2010 and 2021, making maize importation necessary despite implementing resilient agricultural practices for strengthening capacity for adaptation to climate change. This study sought to analyze impact of climate change on maize production in Zimbabwe from 1971 to 2021. The study focused on determination of long-run, short-run, and causality relationships between climate and non-climatic variables and maize production. The study used ADF unit root test to test stationarity of data. Autoregressive distributed lag model was employed to analyse long-run and short-run relationships, while Granger causality test was applied to analyse causal linkages. Results showed that in the long-run mean temperature (p = 0.001) and area (p = 0.017) were significant factors which affected maize production, while precipitation (p = 0.05) and area (p = 0.05) were significant factors which affected maize production in the short-run. Also, results from Granger causality test showed that there was a unidirectional causal linkage between precipitation and maize production (p-= 0.004), and a unidirectional causal linkage between maize production and area under maize production (p-= 0.027). Generally, findings highlight the need for Government to invest in irrigation system to reduce over reliance on rain-fed maize production.

CORRECTION OF EXOGENOUS RISK FACTORS FOR PERIODONTAL LESIONS IN PATIENTS WITH NON-ALCOHOLIC FATTY LIVER DISEASE AND THEIR SPOUSES

Reduction of periodontal adaptive capacity to the constant action of exogenous factors occurs against the background of non-alcoholic fatty liver disease. Correction of such factors creates favorable conditions for the treatment and prevention of comorbid pathology. The study involved 44 married couples and 25 somatically healthy patients who were clinically examined by a dentist and a gastroenterologist, and questioned about their eating habits and oral care. It was determined that the most common habit among the subjects was the abuse of simple carbohydrates. In 88.6% of patients in the main group, inflammatory periodontal disease was diagnosed, the most common clinical form in 61.3% of patients was chronic generalized periodontitis of the second degree of severity, while in the observation group such pathology was detected in 43.1% of patients (13.6% had chronic catarrhal gingivitis, 20.4% had chronic generalized periodontitis of the first degree). After 12 months of implementation of treatment and prevention measures, there was a significant decrease in the presence of various combinations of habits in patients of both groups with positive dynamics of inflammatory diseases of periodontal tissues.

Диагностика устойчивого развития экономики Китая на основе методов статистического анализа

The article presents the results of diagnosing the sustainable economic development of China through the application of correlation-regression analysis. The methodology proposed by the authors encompasses five stages: defining objectives, data collection and preparation, performing correlation and regression analysis, interpreting results, and assessing economic sustainability. The aim of diagnosing the sustainable development of the national economy is to identify optimal management strategies and facilitate informed economic decisions under conditions of limited resources. The indicators of sustainability utilized in this analysis consist of static indicators spanning the years 2010 to 2022, identified based on the sustainable development model formulated by the International Commission on Environment and Development. In accordance with the criteria of correlation-regression analysis, 23 single-factor linear regression models were selected. Elasticity coefficients were calculated to assess the impact of the factor on the stability of the economy. Based on the results of the analysis, two distinct groups of factors were delineated: those that strengthen and those that undermine the sustainability of China’s economy. Moreover, measures for optimizing sustainable development strategies are proposed, aimed at strengthening the resilience and adaptive capacity of the economic system in the face of evolving challenges.

Adaptation of sterile wheat plants to soil under conditions of root treatment with exometabolites of basidiomycetes

In 2023-2024 the adaptation of wheat at the in vitro stage to ex vitro was studied after transfer to soil and root treatment (50 ml) with the сulture filtrate (CF) of xylotrophic basidiomycetes: Phellinus igniarius PI1, Ganoderma lucidum GL, Ganoderma applanatum GA, Fomes fomentarius FF2 and Lentinula edodes LE. Treatment with CF (without dilution, diluted 10 and 100 times) was carried out when planting the plants in the soil and on the 25th day of their growth. The adaptive capacity of sterile plants to soil was assessed by the survival rate, growth indicators and the content of polyphenols in plant tissue. G. lucidum CL, regardless of 10-and 100-fold dilution, reduced the survival (by 40–60 %) and subsequent growth of wheat (tillering by 1.4–1.6 times, stem biomass by 1.2–7.3 times аnd root growth by 1.8–3.5 times relative to the control without treatment with CF). Against the background of various concentrations of F. fomentarius and L. edodes CF, tillering increased by 1.3–2,0 times, the mass of the aboveground part by 1.3–1.5 times, and roots by 2–6 times. The content of polyphenols in plants depended on the fact of treatment with CF and the type of fungi: in the aboveground part it varied from 16.8 to 25.4 mg/g, in the roots from 19.0 to 29.1 mg/g. In the total structure of polyphenols, the proportion of free forms in the aboveground biomass was 23.7–43.1 % and in the roots – 5.1–9.2 %. An increase in the level of free polyphenols was noted in wheat roots upon application of CF of all tested fungi (except G. lucidum GL). A conclusion was made about the effect of CF on the efficiency of adaptation of sterile plants to soil during the transition period in vitro/ex vitro – positive for F. fomentarius FF2 and L. edodes LE, negative for G. lucidum GL, no significant effect for P. igniarius PI1 and G. applanatum GA.

Climate and soil conditions shape farmers’ climate change adaptation preferences

AbstractClimate change poses a significant threat to agriculture and challenges farmers’ adaptive capacity. Understanding how farmers evaluate and prioritize different climate change adaptation measures under consideration of their natural environment is crucial yet widely overlooked. This study determines the relative importance that farmers attach to different adaptation measures and explores the role of climatic and soil conditions in this context. It uses a best‐worst scaling experiment with German arable farmers in combination with geospatial climate and soil information. Findings reveal a preference for incremental adaptation measures over more transformative ones. However, preferences varied considerably with average local temperature, precipitation, and soil quality. The finding that farmers’ adaptation preferences are highly diverse and context‐specific calls for tailored policies. It is crucial for policymakers to have a thorough understanding of farmers’ adaptation preferences. Based on the results, the study discusses multiple actions that policymakers can take to incentivize farmers to favor more effective adaptation measures.

Youth and Climate Change in Pastoralist Communities in the IGAD's Karamoja Cluster: The Case Study of Turkana County, Kenya

Purpose: This study explores the interaction between youth, climate change, and pastoralism in Turkana County, a climate change hotspot within the IGAD's Karamoja Cluster. The study primarily examines youth's knowledge of climate change, its impacts on their lives, and their involvement in climate action initiatives. Methodology: The study utilizes a mixed-methods approach, combining quantitative data from semi-structured questionnaires with qualitative insights gathered from interviews and focus group discussions. Data collection was conducted in both rural and peri-urban areas in Turkana County, supplemented by a review of secondary information from governmental and non-governmental organizations involved in climate action. Findings: The findings reveal a complex association between youth awareness of climate change, its direct impacts on their livelihoods, and their involvement in climate action. Many youths have superficial knowledge of climate issues, and there is, therefore, a critical need for enhanced education and capacity-building to deepen their understanding of climate change, local and national policies, and global climate processes and actions. Unique Contribution to Theory, Practice, and Policy: The study is grounded on theoretical frameworks of Social-Ecological Theory and Capability Theory to guide the analysis of youth, climate change, and pastoralist livelihoods. This study makes significant contributions to both academic literature and policy development by providing nuanced insights into the role of youth in climate action within the context of pastoralist communities. It underscores the importance of supporting youth-led initiatives and ensuring access to resources that will support them in promoting resilience in the face of climate change. The study's policy implications are particularly noteworthy, as it recommends integrating climate education into local curricula, prioritizing investment in youth-led climate action, and fostering collaboration among young people, local authorities, NGOs, and international organizations. By addressing the unique challenges faced by the youth in pastoralist settings, the findings aim to inform strategic interventions that improve community climate resilience and sustainable development. This study, therefore, advocates for the inclusion of youth perspectives in climate policy discussions, emphasizing their potential as critical change agents in promoting adaptive capacity and sustainable livelihoods within their communities.

Revaluation of the genetic diversity–area relationship by integrating nucleotide and haplotype diversity

Abstract Understanding the genetic diversity–area relationship (GAR) is essential for comprehending how species adapt to environmental changes, as genetic diversity is an indicator of a species' adaptive potential. Variation in environmental adaptation capacity exists among species and animal taxa with different distribution areas, highlighting the importance of understanding the GAR. To obtain a more comprehensive understanding of the GAR in terrestrial vertebrates, we assessed both haplotype diversity–area and nucleotide diversity–area relationships using 25,453 cytochrome c oxidase subunit I (COI) sequences from 142 amphibian species, 574 bird species, and 342 mammal species. We found that both measures of genetic diversity increased with species range size across major animal groups. Nevertheless, the GAR did not differ among animal groups, while haplotype diversity performed better than nucleotide diversity in profiling the GAR, as indicated by higher R2 values. The difference in the modelling fit may stem from the distinct biological and mathematical significance of nucleotide diversity and haplotype diversity. These results suggest that the GAR follows similar rules among different animal taxa. Furthermore, haplotype diversity may serve as a more reliable indicator for assessing the potential effects of area size changes on animal populations and provide better guidance for conserving genetic diversity.

Characteristics of metabolic syndrome in the servicemen with erosive esophagitis in wartime conditions

Background. Among the well-known factors contribu­ting to the prevalence of erosive esophagitis, the leading one is an increase in the number of individuals with obesity and insulin resistance. The assessment of metabolic syndrome in the servicemen of the Armed Forces of Ukraine with erosive esopha­gitis in wartime conditions is of particular importance, as the effectiveness of their professional activities depends on it. The purpose of the study: to evaluate the body composition and insulin resistance in the servicemen of the Armed Forces of Ukraine with erosive esophagitis, taking into account the level of the stress index, exhaustion and adaptative capacity of the body. Materials and me­thods. The study included 24 men aged 33 to 57 years, the average age was (42.7 ± 2.1) years. All military personnel were assessed for maladjustment, increased cardiovascular risk, anxiety, and fatigue using the cardiorhythmography method based on the ana­lysis of heart rate variability on the CONTEC8000GW system. Body composition was assessed using Tanita MC-780МА (Japan) scales-analyzers whose mechanism is based on the technique of bioimpedance analysis with computer processing. Insulin resistance was evaluated using the HOMA-IR index, for the calculation of which the level of insulin was determined by enzyme-linked immunosorbent assay systems of the Xema company (Ukraine) on the Stat Fax 303 Plus analyzer (USA). Results. According to precise diagnostics, half of the servicemen of the Armed Forces of Ukraine with erosive esophagitis were diagnosed with vegetative imbalance, which was manifested by an increase in the stress index in 37.5 % of cases, a disruption or violation of adaptation in 25.0 %, and exhaustion of the body in 54.2 % of cases. The HOMA-IR index was 1.5 times higher (p = 0.006) compared to that of the control group. 37.5 % of the servicemen of the Armed Forces of Ukraine with erosive esophagitis showed signs of metabolic syndrome. Correlation analysis revealed relationship of heart rate variability with body composition indicators (body mass index, fat mass, and amount of visceral fat). In addition, an increase in insulin resistance is associated with an increase in the stress index and cardiovascular risk, as well as a decrease in the adaptive capacity of the body and its exhaustion. Conclusions. The correlations found between indicators of heart rate variability, insulin resistance and body composition will allow for the development of a personalized approach to the management of the servicemen of the Armed Forces of Ukraine with erosive esophagitis.
