In this paper, a framework is suggested to rationally examine the compensatory measures for ES use losses and tested with actual offset cases in developing countries, focusing on endangered coral ecosystems. In the framework, we first evaluate the necessity of compensatory measures for the losses of coral ES (CES) uses then suggest the restoration measures of CES uses instead of provisions for livelihood supports. The restoration measures include the provision of alternative sites and improvements to reduce the environmental load of the uses. The framework revealed that the necessity of compensation measures and the suitable restoration measure are varied depending on the original location and type of the CES uses, even within small areas. Together with optimum offset site selection, restriction of the destructive CES uses, integrating existing community-based resource management schemes, these careful considerations of CES in biodiversity offset provides hint that enable local people to achieving a balance between conservation and use. However, state of CES uses and corals should be monitored to ensure the framework effect. We further discuss the condition to apply this framework.","PeriodicalId":143839,"journal":{"name":"International Journal of Biodiversity and Conservation","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117110681","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}

Still, the global fungal species richness is full of uncertainties as evidenced by various estimates. Estimating fungal species richness and diversity is raising many questions related to the sampling effort (in space and time). This study aims to determine the effect of the sampling technique on the diversity measure and natural productions of wild macromycetes in the soudano-guinean forests. Six concentric plots different in the sizes and in the shape were installed in the Isoberlinia doka dominated woodlands. We recorded the number of fruit bodies and the fresh biomass of the species for each plot from June to October 2017. Dendrometric parameters were assessed by counting individual trees with dbh ≥ 10 within plots. A mixed linear model was applied through lme4 package to assess the influence of the size and shape of the plots on the abundance and species richness of macromycetes. An analysis of variances was used to assess the influence of the size and shape of the plots on the fresh biomass. Results showed that the abundance is higher in square plots at sizes 400 and 625m² but the biomass does not different significantly from one shape of plot to another (P = 0.228). Fresh biomass is higher in rectangular plots compared to the square and circular ones. Highest values of specie richness are obtained in the 25 m² for circular plots.","PeriodicalId":143839,"journal":{"name":"International Journal of Biodiversity and Conservation","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122679055","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}

However, significant lion populations and their suitable habitats in many of their former ranges in Ethiopia have declined over time due to socioeconomic uncertainty and the resulting ecological imbalances. Despite this general trend, it is equally noted that there is a lack of verifiable data which depicts the past and current status of African lions. Thus, very little is known about the species in question in most of its ranges. Available published and unpublished reports and manuscripts on the target species were reviewed in order to examine and document the status of the African lion in Ethiopia. From our review, we concluded that the lion numbers are still low and declining whilst considerable ranges have been identified through the field assessments conducted in the last two decades. African lions in Ethiopia have been under serious threat from various anthropogenic activities and it is therefore recommended to effectively implement the national conservation action plan for lion and undertake further field assessment on its habitats. This study suggests the establishment of a national Red list category for the threatened species based on the final reports of our assessments.","PeriodicalId":143839,"journal":{"name":"International Journal of Biodiversity and Conservation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129762616","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}

Many of the understudied regions face increasing threats from urban development, pollution, and potentially climate change, among other factors. The objective of this study was to examine the diversity of lichens on Mt. Cameroon. To achieve this objective, eight collection sites were surveyed on two flanks of the mountain at elevations ranging from 3 to 2178 m above sea level. The visual estimate sampling method using circular plots was adopted for the survey. Voucher specimens were collected in triplicate and deposited in the herbaria in Limbe and the University Buea. Lichens were identified by studying the morphology and chemical spot test. The morphology of the thallus and reproductive structures were examined under the stereomicroscope at 10×. The K-test, C-tests and KC-spot test were performed for each specimen with KOH and Ca(OCl) 2 . The abundance rating scale, species diversity, similarity and richness indices were computed. Identification by molecular, morphological and chemical spot tests produced a total of 89 species, 22 site-specific species, 52 genera belonging to 27 families and 11 orders. Four lichen specimens were identified to genus level and eighty-five to species level. According to the Cameroon lichen database, 82 of these are new discoveries. Parmeliaceae, Heterodermia, Usnea and Dirinaria applanata dominated the area. The identified species occurred in six growth forms and from nine substrates types. Foliose and corticolous lichens were most represented. Among the sites surveyed, Upper Buea situated on the leeward flank at high altitude >1000 m, recorded the highest diversity and site-specific species.","PeriodicalId":143839,"journal":{"name":"International Journal of Biodiversity and Conservation","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114536773","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}

It is also found in Benin. Its oil is rich in the essential fatty acids (Omega 3, 6), fat-soluble vitamins (A, D, E and K) and trace elements, essential for human health. Currently, few people know about this oil, likely explaining its almost total absence in rural markets in Benin. The species is also neglected, as little scientific data is available on it in Benin, particularly regarding knowledge on its uses where it occurs. With the aim of filling this gap, ethnobotanical surveys were undertaken to assess the uses of the species, identify factors explaining the variation of its ethnobotanical value, and determine its availability and accessibility for local people. Data were analysed using the relative frequency of citation and generalised linear models. In total, eight uses were enumerated, of which six were for medicinal uses and one for cosmetic and handcraft respectively, and mainly based on its stem. The stem of R. heudelotii was mainly used for handcraft by Nagot and Holli socio-linguistic groups and mainly by men from the Pobe phytodistrict. Although individuals of R. heudelotii were absent in southern Benin, its kernel is mainly used for cosmetics and medicine by people from the Fon socio-linguistic group in this region. Field data suggest that the kernels and oil of R. heudelotii in this region mainly come from Cameroon and Côte d’Ivoire. The distance travelled to access the species at the time of this study is two times higher than 30 years before and positively correlated with the use-value (r=0.66, P-value<0.001). Our findings suggest that R. heudelotii is marginally used in Benin, and this might be a threat for its conservation and related knowledge.","PeriodicalId":143839,"journal":{"name":"International Journal of Biodiversity and Conservation","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122778264","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}

This paper introduces three cases such as Ha Long Bay, in Vietnam, Galapagos Islands and Shirakami-Sanchi in Japan which are the sites of world heritage. The paper presents the different values of stakeholders towards world natural heritage. In particular, the paper discusses how the universal values of world heritage and the values of stakeholders including local communities affect the protection of world heritage. Then, based on the recognition of the different values, future issues and perspectives regarding the coordination of interests among stakeholders are discussed. In today's world, where there are different values, sometimes conflicts among stakeholders happen with each other and it is of course needed to respect and mutually understand these different values. On the other hand, the international framework, the World Heritage Convention, is a global standard with outstanding universal value, although its characteristics are diverse. For registered sites, the global \"external\" endorsement should require local communities at the sites to comply with new global standards. At the same time, external global standards will force new changes on the ground in registered sites. It is important to think how to overcome conflicts between different values and to create new values through interaction between external and local values.","PeriodicalId":143839,"journal":{"name":"International Journal of Biodiversity and Conservation","volume":"291 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117325759","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}
