Arg) using secondary information and data harvested from previously published studies found online. Data gathered showed that H. brasiliensis is subject to a plethora of economically important diseases mainly of fungal origin, classified as leaf, stem and branch, panel and root disease. Some fundamental causal organisms of leaf diseases in H. brasiliensis includes Pseudocercospora ulei, Oidium heveae, Colletotrichum gloeosporioides and Corynespora cassiicola. Corynespora leaf fall caused by Corynespora cassiicola is currently accepted as the leaf disease which causes about 45% of yield loss to rubber in mostly Asian and African continents. The symptoms of South American Leaf Blight (SALB) range from discoloration of lamina to death of tree when untreated. Leaf disease symptoms range from white powdery patches to shriveling and falling off of tender leaves and translucent brownish yellow spots in semi-matured leaves in Oidium leaf disease. Colletotrichum leaf disease symptoms range from necrosis of tender leaves of young plants to defoliation and death of entire plant. Disease control is achieved by the use of chemicals and planting of disease-resistant varieties. Some phylloplane fungi are prospective biological control agents. The best treatment to manage Corynespora leaf fall disease (CLFD) in nurseries is the introduction of overhead shading coupled with application of the fungicide mancozeb. Diseases affecting the leaves of H. brasiliensis can be devastating and can lead to loss of multiple rubber trees and reduction in the latex production of the trees. Therefore, adequate preventive, curative and control measures against the diseases should be taking to ensure maintenance of a healthy rubber tree plantation.","PeriodicalId":15093,"journal":{"name":"Journal of Applied Sciences and Environmental Management","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139227133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study revealed the socio-demographic characteristics of community members of Idanre Forest Reserve. Data obtained shows that majority of the community members were aware of Idanre forest reserve and the attitudes and involvement of the local community towards conservation at Idanre forest reserve was negative. Factors that determined local people’s attitudes include assess to benefits obtained from the park. The impact of these benefits on attitudes was shown by the willingness of the people to assist the park management in promoting wildlife conservation. It was concluded that the factors responsible for the negative attitudes and involvement of local members towards nature conservation of Idanre Forest Reserve were majorly the lack of substantial benefits from the reserve and also the unfriendly nature of management. A bottom-top approach is hereby recommended, through regular involvement of local community leaders in major aspect of decision making.","PeriodicalId":15093,"journal":{"name":"Journal of Applied Sciences and Environmental Management","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139217587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nephrectomy and alcohol significantly increased MDA and significantly decreased SOD, CAT and GPx; furthermore, post unilateral nephrectomy administration of alcohol caused advanced significant elevation of MDA as well as advanced significant depletion of SOD, CAT, and GPx of the kidney tissue. This study demonstrated for the first time that post-unilateral nephrectomy intake of alcohol enhances kidney oxidative stress by increasing kidney lipid peroxidation (MDA) and inhibiting its antioxidants (SOD, CAT, GPx); forming basis for campaigning against alcohol intake after unilateral nephrectomy as well as folk treatment with alcohol which may involve an individual that underwent nephrectomy.","PeriodicalId":15093,"journal":{"name":"Journal of Applied Sciences and Environmental Management","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139222542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research findings highlight a predominant presence of married female marketers in the 25-30 age bracket, primarily equipped with secondary school education. Catfish (Clarias gariepinus) emerge as the favoured fish species, and the primary mode of transportation to these markets is public. Notably, refrigeration stands as the preferred storage method for unprocessed fish, with peak sales occurring in the afternoons during the dry season. Among the key discoveries, inadequate financial resources surface as the predominant external challenge faced by marketers, impacting the efficiency of their operations. To address these findings, we recommend the formation of cooperatives to facilitate access to financial resources through banks and government agencies. Additionally, investments in essential infrastructure such as smoking facilities (smoking kilns) are essential to mitigate adverse health effects on marketers. Furthermore, government intervention through educational seminars and awareness programs is suggested to empower smoked fish marketers to enhance their marketing strategies. Lastly, the implementation of price control measures is advised to mitigate price fluctuations faced by producers, retailers, and consumers, fostering a more stable and equitable market environment.","PeriodicalId":15093,"journal":{"name":"Journal of Applied Sciences and Environmental Management","volume":"175 12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139222681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
