Effective tropical freshwater biodiversity conservation requires prioritised and concerted action that is informed by science, but efforts to synthesise the available expertise and knowledge remain lacking to date. Here, we identify the most important challenges for freshwater conservation in the tropical biodiversity hotspot Sundaland, and provide roadmaps towards addressing them. A Delphi technique for consensus building, adopted across a panel of 18 experts, identified challenges under the categories of threats, research needs, and social and policy-related challenges. Threats were ranked by their importance in terms of the spatial extent, severity and persistence, while research needs, and social and policy-related challenges were ranked according to how severely they impede conservation. The top-ranked challenges were (1) threats: deforestation, agriculture, urbanisation, water management; (2) research needs: lack of data on freshwater biodiversity, systematic biology, understanding multiple stressors and resilience of freshwater ecosystems; and (3) social and policy-related challenges: low priority of freshwater biodiversity, lack of expertise, lack of systematic conservation planning, and growth of population and affluence. Addressing these challenges requires an approach that integrates improved communication and collaboration among researchers and stakeholders, scientific outreach to improve public appreciation of freshwater biodiversity and build capacity, implementation of best practices to mitigate negative human impacts, systematic conservation planning, and adoption of novel tools and technologies to address important knowledge gaps. This work can serve as a model for prioritising conservation actions in other regions that lose biodiversity at similarly rapid rates.</div></div>","PeriodicalId":55375,"journal":{"name":"Biological Conservation","volume":"299 ","pages":"Article 110839"},"PeriodicalIF":4.9,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142578358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

It ensures a species to adapt to warming and increasingly stochastic environments, and to recover following extreme events. Here we investigate the selective effects of spatial management on intraspecific genetic and phenotypic variation of two sympatric but genetically distinct Atlantic cod ecotypes in a Norwegian fjord. We found that phenotypic differences between sympatric cod genotypes were mainly driven by morphological and metabolic traits. Offshore cod had higher metabolic maintenance costs at cool temperatures but lower aerobic capacity at warm acclimation than coastal ecotypes, indicative of thermal constraint of aerobic physiological processes beyond metabolic maintenance. Offshore cod also had larger and thicker peduncles and better body condition. We found that protection benefits from the no-take zone (NTZ) of the Tvedestrand marine protected area were independent of individual space-use size, but instead resulted from ecotype-specific differences in habitat occupation. Results specifically show that the current delimitations of the NTZ do not cover habitats occupied by the coastal and highly resident cod ecotype which shows greater metabolic thermal tolerance but is considered to already be in a depleted state. Our study exemplifies why protecting intraspecific diversity is directly relevant for management implementations aimed at reducing the impact of further selection pressures such as ongoing environmental change. Careful investigation of intraspecific diversity and integration of such knowledge to fisheries management and design of protected areas may prevent unwanted additional selective pressures and contribute to offer broad protection to genotypes and phenotypes.</div></div>","PeriodicalId":55375,"journal":{"name":"Biological Conservation","volume":"299 ","pages":"Article 110831"},"PeriodicalIF":4.9,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142555053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Previous research has focused on the trade of bats (Chiroptera) for food and medicine but little is known about the online, international trade in bat taxidermy and specimens, which is thought to be an emerging threat. We aimed to characterise this trade by sampling two major e-commerce platforms over an 18-month period. We used an automated pipeline, whereby data were accessed programmatically; filtered using a neural-network classifier; and the locations and species mentioned in relevant listings were identified using Named Entity Recognition. We retrieved 40,412 relevant results, representing 2363 and 2116 unique listings from Etsy and eBay, respectively. Although the accuracy of listings could not be verified, most (57 %) provided species-level information. Hence, 47 bat species were listed for sale, of which 32 are not currently identified by the IUCN Red List as traded for any purpose. The highest number of listings were sold from USA, Hong Kong and the UK, whilst traded species' ranges were predominantly located in South East Asia. We provide one of the first longitudinal datasets on the online bat trade, indicating that several species are being traded at potentially high volumes, with demand from North America and Europe driving exploitation in South East Asia. This is concerning for highly-traded species which occur at low densities, such as the painted wooly bat <em>Kerivoula picta</em>. Our automated pipeline can be used for subsequent monitoring of this trade, or could be adapted for monitoring of trade in other taxa.</div></div>","PeriodicalId":55375,"journal":{"name":"Biological Conservation","volume":"299 ","pages":"Article 110827"},"PeriodicalIF":4.9,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142527337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Therefore, this paper proposes a method to identify conservation and restoration priority areas to supplement existing PAs. A case study was conducted focusing on Yunnan, southwestern China, which intersects with three world biodiversity hotspots. First, the spatial ranges for 3768 representative conservation plant species were mapped using species distribution models. Subsequently, planning units were classified into three restorability categories, namely no-need restoration, potentially restorable and non-restorable units, according to land cover changes between 2000 and 2020. Then, conservation and restoration priority areas were identified by applying a two-step systematic conservation planning process. Finally, replacement cost analysis was applied to compare the effectiveness of existing PAs and the overall 30 % priority areas. Northwestern, southwestern, and southeastern Yunnan have high biodiversity conservation values. Especially in eastern and southeastern Yunnan, large amounts of restoration priority areas were identified. Conservation and restoration priority areas account for 15.80 % and 3.69 % of Yunnan's land, respectively. Compared to existing PAs, conservation priority areas can increase the number of species covered from 2461 to 3277, and further to 3566 when including restoration priority areas. Compared to existing PAs, the mean species coverage in the overall 30 % priority areas has increased from 27.28 % to 72.69 %. Notably, 12.86 % of existing PAs were identified as restoration priority areas. This study indicates that in addition to conservation measures, implementing restoration strategies in high conservation-value areas is equally important.</div></div>","PeriodicalId":55375,"journal":{"name":"Biological Conservation","volume":"299 ","pages":"Article 110826"},"PeriodicalIF":4.9,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142527336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

In the Hawaiian Islands, stemming these losses has proven difficult as the highly specialized avifauna are often impacted – among other things – by poorly understood trophic disruptions as well as persistent climatic shifts. Here we investigate these dynamics by examining the trophic positions of 7 different taxa of producers and consumers across the last century in the subalpine māmane (<em>Sophora chrysophylla</em>) forest ecosystem on the island of Hawaiʻi. From museum collections and contemporary sampling, we analyzed the stable nitrogen (δ¹⁵N) values of producers and consumers to identify trophic and source amino acids and derive trophic enrichment constants specific to this food web. This enables us to reconstruct the diet of the palila (<em>Loxioides bailleui</em>), a critically endangered finch whose population recently declined 90 %. Our results show that from 1890 to 2006, the palila trophic position declined from 2.6 to 2.2, with cascading implications for its diet. Bayesian mixing model reconstructions indicate that palila trophic position changes likely arose from a 76 % decline (69.3 % to 16.6 % of diet) in the consumption of native moth caterpillars, and a 172 % increase (30.7 % to 83.4 %) in native plants. From the available ecosystem variables, exploratory Bayesian multiple regressions selected surface temperature changes, and the interactions of surface temperatures with drought and caterpillar parasitism as the primary drivers of these trophic changes.

Through novel interdisciplinary research that integrates botany, ecology, remote sensing, history, and ethnology, we explored two villages (Radenka, Suvi Do) with different ethnic backgrounds. Our primary objectives were to assess grassland plant diversity, correlate it with applied farming practices, and highlight the importance of interdisciplinary research in conservation of semi-natural grasslands. We focused on vascular plants, bryophytes, and lichens that occur within randomly selected nested plot series, covering seven different spatial scales. The semi-natural grasslands in both villages exhibited remarkable plant diversity compared to other temperate meso-xeric and mesic grasslands in Europe. Integral parts of the historic farming system, such as the ancient practice of spring and autumn grazing of hay meadows, are still preserved there. Similarly, the timing of mowing and grazing based on traditional feasts continues to be observed. However, comparison of management intensity over the last 36 years indicates gradual abandonment in all studied parcels, due to severe depopulation, decline in livestock numbers, and a shift from milk to meat production. We advocate encouraging traditional grassland management practices to maintain high plant diversity.
