Mangroves have been exploited beyond their sustainable potential due to increasing reliance on natural resources. The goal of this study was to see how anthropogenic activities affect faunal and floral distribution. The sites chosen for the study were mangrove areas of Shiroda and Assolna in south Goa. The mangroves of the two sites studied, showed variations in the physicochemical parameters of the water due to the anthropogenic activities associated with it. Anthropogenic activities caused more perturbations in the Shiroda mangrove ecosystem. The water quality at Shiroda site was altered by having high concentration of calcium and sulphates. Hardness, TDS and calcium exceeded the permissible limits. Both studied sites showed similar species indices of fauna but differed in richness. Species diversity of crustaceans, Aves, mammals and Actinoptergii was higher for Assolna as compared to Shiroda. From the present study, it can be inferred that ecological disturbance on account of anthropogenic activities decreases the species richness and evenness of specific fauna.","PeriodicalId":272222,"journal":{"name":"New Visions in Biological Science Vol. 2","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114681002","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 chromatographic profile was determined by high performance liquid chromatography, the quantification of flavonoids and antioxidant activity were performed by spectrophotometric method. It was observed in the extracts of all analyzed structures, of the two species (M. flexuosa and M. armata), the presence of flavonoids and also antioxidant activity. The phytochemical profile of the wine evidenced the presence of secondary metabolites reported in other structures of M. flexuosa. In the chromatographic analysis, it was observed that the evaluated extracts have between three and nine compounds. Further studies must be carried out to identify the active compounds in both species.","PeriodicalId":272222,"journal":{"name":"New Visions in Biological Science Vol. 2","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130587546","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}

His comments have been used by creationists and other opponents of the theory, even though he himself did not support their views. In this paper Hoyle’s critique of one aspect of Neo-Darwinism is analyzed to see what merits it may have. The conclusion is that while Hoyle’s mathematics is impeccable, and thus his critique based on them has merit, he did not carry his own reasoning far enough and specifically failed to consider the possibility of large variations in selective value. This may have been due to his belief that such variations would be extremely unlikely, due to an assumption that such variations would be governed by a normal distribution. However, if a heavy-tailed distribution is involved, such variations become feasible. The net result is that evolution in its early stages may have involved large jumps, which, though infrequent, would move it along. The objective of this study is to analyze the impact of Hoyle’s results and how they are affected by modern knowledge of heavy-tailed distributions.","PeriodicalId":272222,"journal":{"name":"New Visions in Biological Science Vol. 2","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134350261","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}
