Although Xerophyta spekei is widely used for the management of diabetes among the Embu and Mbeere communities in Kenya, it has never been empirically evaluated for its hypoglycemic activity. This study was carried out to verify the hypoglycemic activity of dichloromethane (DCM) extract of Xerophyta spekei as well as its antioxidant activity using various in vitro techniques. Phytochemicals associated with its antioxidant activity were identified through GC-MS. Data were subjected to descriptive statistics and expressed as mean ± standard error of the mean (X̄ ± SEM). Comparison between various variables was performed by using unpaired Student’s t-test and one-way analysis of variance (ANOVA), followed by Tukey’s post-hoc test. The confidence interval was set at 95%. The obtained results were presented in tables and graphs. Results showed that there was no difference in α-amylase inhibition activity between the plant extract and the standard (IC50 525.9 ± 12.34 and 475.1 ± 9.115, respectively; p > 0.05). Besides, the glucose adsorption activity of the extract increased with an increase in glucose concentration (from 5.89 to 32.64 mg/dl at 5 mmol and 30 mmol of glucose, respectively; p < 0.05). The extract also limited the diffusion of glucose more than the negative control (7.49 and 17.63 mg/dl, respectively; p < 0.05). It also enhanced glucose uptake by yeast cells. In addition, the studied plant extract showed notable antioxidant activities. The therapeutic effects exhibited by this plant in managing diabetes mellitus and other ailments could be due to its antioxidant as well as its hypoglycemic activity. The study recommends the evaluation of X. spekei for in vivo hypoglycemic and antioxidant activities. Besides, the isolation of bioactive phytochemicals from the plant may lead to the development of new hypoglycaemic agents.","PeriodicalId":21726,"journal":{"name":"Scientifica","volume":"7 6","pages":""},"PeriodicalIF":3.2,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139147860","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}

Due to its pivotal role in energy transfer from lower to higher trophic levels, this species is a crucial component of the ecosystem's functioning. The ecological role of &lt;i&gt;Merluccius merluccius&lt;/i&gt;, off the Moroccan Mediterranean Sea (southern Alboran Sea), was investigated, exploring seasonal and ontogenetic shifts, geographical variations in prey composition, and feeding strategy. Between November 2020 and July 2022, a total of 402 hake specimens were collected by oceanographic bottom trawl surveys (MEDITS) that were carried out during warm and cold seasons to assess their diet and feeding habits. The sample was analyzed according to fish sizes and seasons, and qualitative/quantitative feeding indices were calculated. The trophic spectrum of &lt;i&gt;Merluccius merluccius&lt;/i&gt; included 24 prey items in total, mainly belonging to &lt;i&gt;Osteichthyes&lt;/i&gt; (12), &lt;i&gt;Crustacea&lt;/i&gt; (10), &lt;i&gt;Cephalopoda&lt;/i&gt; (1), and &lt;i&gt;Polychaeta&lt;/i&gt; (1), suggesting a generalist behavior of this predator as in numerous regions of the Mediterranean Sea, with several species that occasionally occurs in its diet. In the Moroccan Mediterranean Sea, &lt;i&gt;Osteichthyes&lt;/i&gt; proved to be the most important prey item (%IRI = 78.56) among the different zoological groups, followed by &lt;i&gt;Crustacea&lt;/i&gt; (%IRI = 16.22). The other food items were occasionally and randomly consumed, and cannibalism was low (0.8%). Hierarchical cluster analysis and nonmetric multidimensional scaling (nMDS) showed different feeding habits of two main groups separated at 60% similarity: small specimens &lt;10 cm TL, primarily feed on zooplanktonic prey, while medium and large specimens hold a diet based on &lt;i&gt;Osteichthyes&lt;/i&gt; with crustaceans. Furthermore, a significant positive relationship between hake and fish prey size was confirmed. Seasonally, mesopelagic &lt;i&gt;Osteichthyes&lt;/i&gt; were the main food prey in the summer season, while pelagic species were predominant during the autumn. SIMPER analysis revealed that the prey items contributing the most to the differences between seasons and length classes were &lt;i&gt;Engraulis encrasicolus&lt;/i&gt;, &lt;i&gt;Micromesistius poutassou&lt;/i&gt;, &lt;i&gt;Boops boops&lt;/i&gt;, &lt;i&gt;Macroramphosus scolopax&lt;/i&gt;, gobids, &lt;i&gt;Gadiculus argenteus&lt;/i&gt;, and most of &lt;i&gt;Crustacea&lt;/i&gt;. The diet does not appear to be influenced by sex (&gt;0.05). A trophic level (TROPH) of 4.1 was calculated, indicating that the species is a top predator (quaternary consumers). The TROPH values ranged between 2.58 and 4.38 from juveniles to adults, increasing asymptotically with the size of specimens. In contrast to what has previously been found in other Mediterranean regions, where ichthyophagous hake feed mostly on pelagic &lt;i&gt;Osteichthyes&lt;/i&gt;, such as &lt;i&gt;Engraulis encrasicolus, Sardina pilchardus&lt;/i&gt;, and &lt;i&gt;Micromesistius poutassou&lt;/i&gt;, the study points up the vital role played by Atlantic horse mack","PeriodicalId":21726,"journal":{"name":"Scientifica","volume":"2023 ","pages":"8865128"},"PeriodicalIF":3.2,"publicationDate":"2023-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10764652/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139098633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is a notable absence of comprehensive research on these services. Assessing carbon sequestration in private forests can have economic advantages for forest owners by promoting resource conservation and contributing to greenhouse gas reduction. This study aims to estimate and compare carbon stocks in private forests located in two distinct physiographic regions of Nepal while also identifying the factors influencing these carbon stocks. The analysis focuses on 16 private forests (with 0.1 to 0.5 hectares) each from Chitwan district (Terai region) and Kavrepalanchok district (Hilly region). Field data collection involved direct measurements of tree and sapling diameter at breast height (DBH), as well as height and class of trees and poles, utilizing a total enumeration method. These collected values were utilized to calculate aboveground biomass (AGTB), aboveground sapling biomass (AGSB), belowground biomass, and carbon stock. Private forests of Terai region were dominated by Shorea borneensis, Tectona grandis, and Dalbergia sissoo, whereas the Hilly region was dominated by Pinus patula, Alnus nepalensis, Schima wallichii, and Quercus leucotrichophora. The aboveground biomass carbon in the Terai region's private forests was estimated to be 83.53 t·ha−1, while in the Hilly region, it was 37.32 t·ha−1. The belowground biomass carbon in the Terai region's private forests was found to be 21.72 t·ha−1, compared to 9.70 t·ha−1 in the Hilly region. Consequently, the estimated total carbon stock in the Terai and Hilly regions' private forests was 105.25 t·ha−1 (386.26 t·ha−1 CO2-eq) and 47.02 t·ha−1 (172.57 t·ha−1 CO2-eq), respectively. Carbon sequestration in the Terai region's private forests was discovered to be 2.24 times higher than that in the Hilly region. These findings underscore the significant potential of private forests, which can generate economic benefits through carbon trading and leverage mechanisms such as REDD+/CDM to promote sustainable conservation practices.","PeriodicalId":21726,"journal":{"name":"Scientifica","volume":"22 23","pages":""},"PeriodicalIF":3.2,"publicationDate":"2023-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138601810","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}

AQ had the greatest arthropod diversity (<i>H</i> = 2.642), dominated by <i>Olios</i> spp., followed by BL (<i>H</i> = 2.444), dominated by a tettigonid species, <i>Oxytate</i> spp. and <i>Psechrus</i> spp. PN was third (<i>H</i> = 1.411), dominated by <i>Dicaldispa</i> spp. PNEN had the lowest (<i>H</i> = 1.3500), dominated by an ant species. Contrastingly, PNEN had the highest plant diversity (<i>H</i> = 2.614) and PN, the lowest (<i>H</i> = 0.879). In AQ, BL, and PN, the arthropod diversity was linearly dependent on plant diversity (<i>R</i><sup>2</sup> = 0.423, <i>p</i> ≤ 0.001), whereas it was not so when PNEN was also included (<i>R</i><sup>2</sup> = 0.008, <i>p</i> ≤ 0.001). This shows that higher plant diversity contributes to greater arthropod diversity in ecosystems where human intervention is minimal. But this pattern was not visible in PNEN, which is an artificially created ecosystem.</p>","PeriodicalId":21726,"journal":{"name":"Scientifica","volume":"2023 ","pages":"7608236"},"PeriodicalIF":3.2,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10667053/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138462552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Indonesia, ranked eighth globally as a producer of oranges, is one of the countries with high genetic diversity of oranges. This diversity is distributed across various regions of Indonesia, including South Sulawesi. Despite the advancements in DNA-based molecular marker techniques for assessing genetic diversity, information on orange diversity in South Sulawesi is currently unavailable and under-researched. In this study, random amplified polymorphic DNA (RAPD) markers were utilized to analyze the genetic diversity of oranges in five production centers in South Sulawesi. Leaf samples of 13 orange varieties were collected from the five production centers: Pangkep, Sidrap, Bantaeng, North Luwu, and Selayar in South Sulawesi, Indonesia. Genomic DNA extraction from the orange leaves followed the protocol of the DNA Mini Kit Geneaid. DNA amplification was carried out using the RAPD method with 14 primers: OPE-04, OPH-04, OPH-15, OPN-14, OPN-16, OPR-08, OPR-20, OPW-06, OPW-09, OPX-07, OPX-11, OPX-17, UBC-18, and UBC-51. The RAPD primers yielded 109 amplified fragments ranging in size from 200 to 2000 base pairs (bp), and all RAPD primers showed 100% polymorphism. The genetic diversity value (He) of oranges in South Sulawesi was moderate (0.236). Cluster analysis based on a similarity coefficient of 77% divided the 175 orange genotypes into five groups. The most closely related genotypes were SB6 and SB7, exhibiting 100% similarity, followed by genotypes JS8 and JS9 and JS13 and JS17, with genetic similarities exceeding 99% for each pair. Genotypes P9 and SI5 displayed the highest genetic distance, with a similarity coefficient of 57%. The dendrogram diagram can serve as a basis for selecting desired plant traits in the improvement of plant characteristics through both conventional breeding and genetic engineering activities.","PeriodicalId":21726,"journal":{"name":"Scientifica","volume":" 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135340951","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}

A total of 100 informants were sampled from four study sites, and questionnaire surveys, semistructured interviews, ranking, and transect walk techniques were employed for data collection in midland, lowland, and highland agroecology and natural forests, riverine forests, and farmlands. Vast sources of the traditional healing knowledge of plant species conveyed from one generation to the next by word of mouth were from a family. A total of 101 medicinal plant species were identified from the study site, which belong to 95 genera and 49 families. These medicinal plants are used to treat about 35 types of human ailments. Families Fabaceae and Poaceae were represented by the highest number of medicinal plant species, followed by the <i>Asteraceae</i>, <i>Lamiaceae</i>, and <i>Euphorbiaceae</i> species. Out of the total medicinal plants' species, 46.53% were herbs and 33.66% were shrubs. Most of them have medicinal properties in their leaf, root, seed, bark, stem, latex, sap seed, and fruits. Medicine from these plant parts is prepared in fresh, dried, and both fresh and dried states. The highest informant consensus was documented for the plant <i>Ocimum lamiifolium</i> used by 75% of informants for its medicinal value in treating fibril illness. <i>Cucumis ficifolius</i> and <i>Eucalyptus globules</i> are used by 41% and 39% of informants ranking second and third, respectively, for their medicinal value. This study revealed that indigenous knowledge of traditional medicine is still popular among local communities in the study area. The conservation strategy practiced by local people is not enough to tackle the erosion of plant species from their habitats. Thus, the conservation of these plants and the associated knowledge base is very essential.</p>","PeriodicalId":21726,"journal":{"name":"Scientifica","volume":"2023 ","pages":"5575405"},"PeriodicalIF":3.2,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10632060/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72015322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
