However, differences were detected in the comparison between degrees of fullness, demonstrating that there is significant influence of plastic ingestion in the stomachs volume. It is possible that the discrepant frequencies of occurrence of gut fullness were due to false satiation effects and blockage of the digestive tract provided by the fibres. \u0000 \u0000 \u0000 \u0000 Key words: Pollution, decapoda, ecology, brachyura.","PeriodicalId":143839,"journal":{"name":"International Journal of Biodiversity and Conservation","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121224306","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}

There was upper elevation observed in both richness and diversity of plant species compared to the others with significant P<0.05. Grazing intensity also has significant impact on both species’ diversity, density and area coverage. This shows that the area heavily grazed had less diversity richness and coverage compared to the less grazed (p<0.001) area.

In Cameroon, there is dearth of information on the impacts of ecotourism on biodiversity conservation of protected areas. The main thrust of this study is to examine local population's perceptions of the impact of ecotourism on biodiversity conservation in and around the Campo Ma'an National Park (CMNP). Data were collected from both primary and secondary sources. Primary data were gotten from household survey (N=124), focus group discussions (N=8) and key informant interviews (N=16). From the findings, 44.4% of the local population perceived ecotourism activities contributing to biodiversity conservation of CMNP against 55.6% with contrary views. Spearman rank correlation coefficients and Chi-square test statistics indicated that, variables plausibly influencing local population's perception of ecotourism impact on biodiversity conservation in and around CMNP were age (p<0.10), gender (p<0.50), main occupation (p<0.10), secondary occupation (p<0.10), time spent in the community (p<0.50), and number of children (p<0.50). From the logistic regression model, the main variables affecting the local population's perception were age, gender and time spent in the community. This study recommends the development of ecotourism friendly policies that can accelerate Public Private Partnership for a participatory and sustainable ecotourism approach for biodiversity conservation and livelihood enhancement in and around the CMNP. It also recommends the development of a gender sensitive ecotourism that will fair opportunities for rural women to benefit from ecotourism activities. \u0000 \u0000 \u0000 \u0000 Key words: Ecotourism, biodiversity conservation, perception, adjacent population, national parks, Campo Ma'an National Park, South Cameroon.","PeriodicalId":143839,"journal":{"name":"International Journal of Biodiversity and Conservation","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121061163","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 objective of this study was to assess socio-economic contributions of agroforestry system to smallholder farmers around Jimma town, Southwest Ethiopia. A total of 199 households were proportionally sampled from the three selected sites (Mazora, Waro kolobo, and Merawa). A semi-structured questionnaire was used to collect data from sampled households. Data collected were analyzed using descriptive statistics and an econometric model. The results show that tree-based agroforestry, land-use practice is an integral part of smallholder farmers’ livelihoods in the study sites, and furthermore a tree has socio-economic benefits. An average household income from trees was estimated to be 2592, 4652 and 1922 ETB in Mazora, Waro kolobo, and Merawa sites, respectively. Smallholder farmers appreciated trees more importantly from the socio-economic points of view in home garden, pasture land and woodlot, across sites. Education level, tree planting experience, and major livelihood positively and significantly influenced income derived from tree products, while livestock possession was negatively and significantly affecting income in the study sites. In general, tree-based agroforestry land use practice is the most crucial for improving smallholder farmer’s livelihoods.
