To investigate how the body size attributes of marine nematodes indicate the environmental changes in mangroves, we studied the variations in body size and biomass size composition of marine nematodes in a subtropical mangrove ecosystem. The results revealed that median values of body length, width, length-to-width ratio, and individual dry weight were 956.88 μm, 40.98 μm, 22.51, and 0.24 μg, respectively. In summer, adults and juveniles exhibited a predominance of smaller-sized slender individuals, while in winter, large stout individuals were more common. Correspondingly, the biomass size spectra skewed towards smaller-size classes in summer, whereas in winter, they skewed towards larger-size classes. The body size attributes and biomass size composition of nematodes significantly correlated with environmental variables, effectively indicating the environmental changes, especially changes in interstitial water temperature and sediment pheophorbide. The reduction in body size was a prominent response of mangrove nematodes to temperature rise. The total biomass of nematodes and their carbon contribution have been calculated based on body length and width. This document will provide essential information to estimate the carbon stock of nematodes and their contribution to the blue carbon sink in mangrove ecosystems. Analysis based on body size is species-independent and more beneficial for promoting the application of nematodes in environmental implication and monitoring.</div></div>","PeriodicalId":54264,"journal":{"name":"Global Ecology and Conservation","volume":"59 ","pages":"Article e03545"},"PeriodicalIF":3.5,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143680426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

This study assesses the impact of ILs in the Brazilian Legal Amazon on mining-induced deforestation by comparing it to a counterfactual scenario in the absence of ILs. The results indicate that ILs are effective in avoiding mining-induced deforestation, preventing the accumulated deforestation of approximately 25 million hectares between 2004 and 2019. This corresponds to 20 % of all ILs’ territories and 4.7 % of the Brazilian Legal Amazon extension. Although their effectiveness has declined over the years, this underscores the importance of ILs in protecting nature and indigenous communities.

Using on-board video data, we recorded 675 bird risky crossing events over two years of data collection, totalling 127 journeys and 34,250 km of cumulative travel.

Our findings reveal that certain HSR infrastructure features, such as the presence of tall embankments and surrounding landscape such as nearby open lands (crops and shrubland), significantly increase the frequency of risky crossings. Additionally, we found that species associated with human modified landscapes were particularly prone to these risky crossings, whereas forest birds were rarely observed performing risky crossings. These results highlight that birds’ collision risk is influenced by the biotic changes caused by the HSR.

Our in-depth bibliometric analysis based on multiple online search engines covered the period 1992–2021 and yielded 1064 articles, of which 245 were selected for this review. Publications recorded on DFM came from 25 countries, covering four of the five African sub-regions. Approximately 77 % of the retained publications came from East Africa alone. Community participation, institutional arrangements, and contribution of DFM to forest conservation and community livelihoods were the main foci of the studies. Apart from the Village Land Forest approach, which devolves full power to local communities in Tanzania, most DFM schemes in Africa are implemented through deconcentration or delegation, whereby the local communities are primarily used as a workforce. This resulted in low interest among local people in forestry activities and limited implementation of DFM following the cessation of the initial DFM projects. Our analysis also highlighted gaps in knowledge about DFM regarding adjacent land use, conflict resolution, and ethnobotnical study. Our findings should guide scholars in their future research, as well as decision-makers in developing sound community-based management strategies for tropical forests in the context of their overexploitation and rapid degradation.

Glacial relicts, small populations of arctic-alpine species at the margin of their ecological range are considered reliable indicators of climate change impact. The habitats where they occur are also usually threatened by land use. They are thus an ideal system to study the effect of these two key drivers. We used four vascular plant species (<em>Trifolium spadiceum, Traunsteinera globosa, Gentiana lutea</em> and <em>Bellidiastrum michelii)</em> from wet and cold environments, and used species distribution models to study the effects of climate change on their ranges, incorporating high-resolution environmental data on climate, topography, and geology, alongside species occurrence data from long-term monitoring in SW-Germany. The resulting suitability maps were masked with land use maps, to assess the additional effects of land use. To obtain projections of potential future distributions we additionally modelled distribution under future climate and land use scenarios. Across various future climate scenarios, the suitable area for all species decreased by an average of 60 % on average due to climate change. Land use alone, significantly reduces suitable space, decreasing it by an average of 72 % under current and future climate and land use change scenarios. Despite the severe susceptibility to climate change, our findings reveal an additional, equal or even stronger influence of land use on the distribution of glacial relicts that will precipitate their decline.

To address this uncertainty, we apply a novel vulnerability assessment framework to show how land use configuration modifies the extent of potential harms arising from climate change to gallery forests, an important vegetation type in tropical savannahs. We highlight how the spatial distribution of climate change (specifically, change in annual rainfall) interacts with the spatial distribution of land use (specifically, cropland), as well as the biophysical context of the study site (the W-Arly-Pendjari transboundary protected area in West Africa), to shape the vulnerability of gallery forests to changes in rainfall in the region. Due to the pathways by which rainfall change and land use interact, vulnerability is especially elevated in core protected areas, warranting particular attention from conservation managers.

Bangladesh, a densely populated, tenuous place for human-wildlife coexistence, constitutes ∼ 30 % of the fishing cat’s known distribution range. Based on systematic surveys of media reports (n = 361; 2005–2021), we implemented a novel application of predictive modeling to map fishing cat presence, and hotspots of human–fishing cat negative interactions across Bangladesh. The distribution of fishing cats was best explained by the extent of wetlands and dry-season precipitation.
