The aim of this study is to model potential connectivity between core habitats in the BGFB. First, seven key variables influencing elephants’ choice of corridors were mapped as rasters and ranked using the analytical hierarchy process. Suitability indices were then assigned to the variables based on their relative influence on corridor choice. A total resistance raster was calculated using the weighted sum method. Finally, the Linkage Mapper was used to map potential corridors between pairs of protected areas. Nine potential corridors were identified, with Euclidean distances ranging from 3.89 to 13.50 km, cost-weighted distances from 13.20 to 34.75 km and least-cost path from 4.10 to 16.23 km. The Bia Game Production–Krokosua Hills and Bia NP–Bia North corridors, with centrality scores of 19.16 Amps and 13.14 Amps, respectively, were identified as the most critical corridors in maintaining connectivity. Krokosua, Bia Tano, Ayum, Bonkoni and Bosam Bepo forest reserves, with centrality scores ranging from 36 to 69 Amps, were identified as the critical core areas for maintaining connectivity. This result provides the first comprehensive geospatial dataset on habitat connectivity in the BGFB, which will inform conservation efforts and guide the effective management of habitat corridors to restore population connectivity and support elephant conservation.</p>\u0000 </div>","PeriodicalId":7844,"journal":{"name":"African Journal of Ecology","volume":"63 2","pages":""},"PeriodicalIF":1.1,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study takes the initial step toward developing sustainable harvest strategies by quantifying suitable habitat, estimating each country's contribution to total suitable habitat, estimating the effectiveness of protected areas to capture suitable habitat, and exploring predictor variables affecting the suitable habitat of mopane worms. We employed presence-only modelling to develop an ensemble model that combines generalised additive models (GAM), maximum entropy (MaxEnt), and random forests (RF), resulting in both a full and a restricted ensemble model. The restricted model was constrained to the southern African mopane savannah (<i>Colophospermum mopane</i>) to evaluate potential populations that can sustain harvest within mopane savannah. The full and restricted ensemble models classified 15.1% and 40% of the model landscape as suitable for mopane worms, respectively. Under the restricted model, Zimbabwe contributed 26.8% to the suitable habitat, followed by Botswana (25.3%), South Africa (15.4%), Namibia (14.7%) and Mozambique (11.1%).

This editorial highlights the active role of African IP in biodiversity conservation and food system resilience, emphasising the urgent need to forge equitable partnerships across knowledge systems rather than subordinating TEK to scientific knowledge (SK). TEK, embedded in centuries of observation and cultural practices, informs ecological processes and sustainable resource use. However, climate change, land dispossession and cultural erosion, among other drivers, threaten these knowledge systems and the communities that uphold them. A collaborative approach that respects Indigenous sovereignty can foster interdisciplinary conservation efforts. This aligns with ongoing efforts at the international scene, such as the Kunming–Montreal Global Biodiversity Framework, which explicitly recognises the rights of IP, as well as those of other local communities in multiple conservation targets, including land rights, traditional knowledge and access to justice. The challenge remains: How can these international commitments translate into equitable, rights-based conservation on the ground? It is crucial to ensure that conservation policy and practice are consistent with the United Nations Declaration on the Rights of Indigenous Peoples and uphold moral responsibility. Equally important is fostering shared interests between conservationists and IP by engaging in open dialogue about conflicts of interest and building trust with Indigenous communities. By integrating these principles, conservation and ecological sciences can move beyond theoretical commitments to genuine, participatory conservation efforts that respect and sustain IP's stewardship of nature.</p>","PeriodicalId":7844,"journal":{"name":"African Journal of Ecology","volume":"63 2","pages":""},"PeriodicalIF":1.1,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aje.70030","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143481507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, diverse taxonomic groups worldwide are affected by vehicle collisions, including reptiles, amphibians, mammals and birds. Ecologically, WVC results in population declines and can differentially affect animal populations. Yet, monitoring biodiversity and examining the factors influencing its alterations enable society to make informed decisions on conservation and enhance the management of human–wildlife conflicts. Effective mitigation techniques necessitate knowledge about the location and timing of traffic casualties involving wildlife. The objectives of this study were as follows: (i) to analyse the trends in WVC and (ii) to forecast future scenarios of WVC in the Hurungwe Safari Area (HSA), located in the Mid Zambezi Valley, Zimbabwe. The study aims to develop evidence-based strategies tailored to the local context and feasibility for reducing WVC frequency and severity. We used WVC data for 22 different species collected by the Zimbabwe Parks and Wildlife Management Authority (ZPWMA), Marongora Field Station. This study performed a trend analysis and then forecast future WVC using time series methods. We used K-means to determine clusters in the species data. Time series forecasting was performed using the Autoregressive Integrated Moving Average (ARIMA), a popular statistical method used for time series forecasting. Our results indicated an exponential growth in the number of WVC for some animal species, that is, civet, buffalo, hyena and waterbuck by the year 2030. Modelling trends in WVC is important for protecting wildlife, enhancing road safety and reducing economic costs. It informs conservation efforts, guides effective management strategies like wildlife crossings, and raises public awareness about the impact of driving on ecosystems. This data ultimately promotes coexistence between humans and wildlife.</p>\u0000 </div>","PeriodicalId":7844,"journal":{"name":"African Journal of Ecology","volume":"63 2","pages":""},"PeriodicalIF":1.1,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143455941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We collected visual and auditory count data over 13 years from 19-point count stations systematically located across the wetlands and applied distance analysis to assess the abundance and distribution of GSW across years and wetlands. Then, we employed Generalised Additive Mixed Models (GAMM) to assess the relationship between GSW abundance and specific factors known to impact wetlands: trampling by large mammals, the presence of non-wetland plant species, or the absence of water. Additionally, we investigated how wetland sizes influenced this relationship. We found that the focal wetlands within VNP support an approximate mean of 3.143 (95% CI: 2.578–3.831) clusters of GSW per hectare, hosting a mean of 3.634 (95% CI: 2.960–4.462) individuals per cluster.
