Although native to Africa, oil palm is grown throughout the humid tropics, and the largest producers are now in Southeast Asia. In many regions of cultivation, oil palm has been identified as a leading cause of deforestation and biodiversity loss. In Sierra Leone, oil palm grows wild in secondary forest and fallow land, as well as in plantations; research into its impact on biodiversity is limited. The effects of natural (wild) and plantation oil palm on the avifauna of southeastern Sierra Leone was examined. Over a two-year period, point-count surveys of birds were conducted on six occasions during the wet and dry seasons. Four plots were established in each of the six land-use types: Primary Forest, secondary forest, farm-bush with few oil palms, farm-bush with many oil palms, small plantations and larger plantations. Results from the study suggest that small-scale oil palm plantations, even under traditional low-intensity management, have a reduced avifauna compared to farm-bush. The difference between secondary forest and farm-bush is small, suggesting that traditional management of oil palm as a “non-timber forest product” is less detrimental to biodiversity.","PeriodicalId":143839,"journal":{"name":"International Journal of Biodiversity and Conservation","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139201372","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}

Rehabilitation of degraded land is challenging due to moisture limitations and drought. This study evaluated rangeland-based integrated watershed management. Three soil and moisture conservation structures were applied, and multi-purpose tree/shrub species like Faidherbia albida, Melia azedarach , and Moringa stenopetala were planted. Data on indigenous plant species regeneration, diversity, species richness and biomass, survival rate, and height growth of planted tree species were collected. After the intervention, the indigenous plant species' regeneration, diversity, and richness significantly increased. The mean indigenous plant species richness, biomass, and basal cover were highest in half-moon followed by soil level bund and, lowest in control. The survival rate and the height growth of all planted MPTs species were better under Negarim and half-moon and lowest under control treatments. This suggests that soil and moisture conservation structures are more suitable than the conventional method of rehabilitation of indigenous plant species and tree planting. Even though the survival and growth of tree seedlings were best under Negarim, the herbaceous diversity, biomass, and basal cover of herbaceous were low, and construction of this structure was labor incentives than the other two structures.","PeriodicalId":143839,"journal":{"name":"International Journal of Biodiversity and Conservation","volume":"307 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139307970","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}

Despite this prevalence, research on rural women’s experiences with human-wildlife conflicts is limited. To address this research gap, this study examined the impacts of HWC on rural women from two villages neighboring Mikumi National Park (MNP) in Southeast Tanzania. A total of 20 adult female victims of human-wildlife conflicts (HWC) were purposely selected and interviewed to understand the impacts of human-wildlife conflicts in their lives. Findings indicate that loss of grassland and water within MNP borders exacerbated by climate change are pushing wild animals from MNP to seek food in nearby villages, causing frequent human-wildlife tensions. Crop damages, livestock killings, household food insecurity, and fears for physical safety were found to be significant impacts of HWC increasing rural women’s vulnerability to poverty. Despite these conservation threats, most interviewed HWC victims receive very little support from conservation authorities threatening the survival of wild animals from MNP. For peaceful co-existence, the study recommends empowering rural women with conservation training on HWC prevention and investment in the large-scale restoration of degraded lands and water sources to reduce competition over natural resources between humans and wildlife.","PeriodicalId":143839,"journal":{"name":"International Journal of Biodiversity and Conservation","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125963385","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}

During the peak period of stress (July and August), mean photosynthesis rates of both species were lower than during more moderate weather in early summer and in autumn. Leaf fluorescence analyses indicated that the mean F v /F m values, combining the data for both species, were fairly similar across the 5 months suggesting that the quantum yield efficiency of photosystem II may be less susceptible to climate stress. However, there was a significant positive correlation between ET 0 /RC values and net photosynthesis rate (r = 0.68, n =10, p = 0.03). This indicates that some of the variation in photosynthesis rates between species across the summer weather pattern may be accounted for by the rate of transfer of electrons from PS II through the intermediate quinone to the site of CO 2 fixation as measured by the ET 0 /RC variable. Dark respiration rates were lower for both species during the most severe heat and drought in July and August.","PeriodicalId":143839,"journal":{"name":"International Journal of Biodiversity and Conservation","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139353255","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}

To achieve this, a household survey was conducted using simple random sampling technic where each household was given equal opportunity of being selected to take part in the survey. Line transects questionnaires and a selection of some Participatory Rural Appraisal (PRA) tools were used to source information. A total of 600 questionnaires were administered in 10 villages. The results showed no significant contribution of MCNP activities to livelihood of the local people. Implemented innovative income programs had not yet attained optimum production level. Household income level was perceived to have increased slightly. Previous income activities that impacted negatively conservation such as small-scale logging and shifting cultivation have been abandoned and replaced mainly by innovative income programs such as agroforestry farming, mixed crop farming and sustainable debarking of Prunus africana . However, the sustainability of the innovative income activities would require a more practical match making approach for management.","PeriodicalId":143839,"journal":{"name":"International Journal of Biodiversity and Conservation","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124700615","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 evaluate the effects of tillage practices (conventional tillage and no-tillage) and fertilizer types (synthetic, organic, and no fertilizer) on soil MBC. The field experiment, located in Buea, was arranged in a split-plot design with three replications and had tillage systems as main plots and fertilizer types as sub-plots. Soil samples were collected at 0–15 cm depth at an interval of 4 (early season), 8 (mid-season) and 12 (late season) weeks during the 2020 and 2021 minor and major growing seasons respectively, for the determination of soil MBC by the chloroform fumigation and extraction method. The findings of the study showed that the main effect of tillage practice and fertilizer types was unsignificant (p>0.05) in the 2020 and 2021 study season throughout the sampling period. Plots under zero tillage with control experiments (No.Till:CON) recorded the highest soil MBC in the 2020 season (201 kg -1 respectively) while in the 2021 season, plots under zero tillage with organic fertilization (No.Till:ORG) recorded the highest (400.4 mg kg -1 ) soil MBC. Soil MBC was higher in the 2021 season than in the 2020 season. These findings suggest that the use of compost in combination either conventional tillage or no-tillage in farms in the study area could potentially enhance soil MBC.","PeriodicalId":143839,"journal":{"name":"International Journal of Biodiversity and Conservation","volume":"95 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":"128885183","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}
