The Antarctic Treaty area is under international consensus-based governance through the Antarctic Treaty Consultative Meeting (ATCM), which first provided for the designation of Antarctic Specially Protected Species (SPS) in 1964. Over the past 60 years, only the fur seals (genus <em>Arctocephalus</em>) and Ross seal (<em>Ommatophoca rossii</em>) have been listed as SPS, with the fur seals subsequently having been de-listed in 2006. The SPS conservation tool has therefore remained little used by the ATCM. The Committee for Environmental Protection (CEP) was established to provide advice on environmental issues to the ATCM. Through its Five-year Work Plan and Climate Change Response Work Programme, the CEP agreed to develop management actions to maintain or improve the conservation status of threatened species, e.g., through SPS Action Plans. To help the CEP in its work, we examined the history of SPS designation under the Antarctic Treaty system, considered the current conservation status of Antarctic species as provided in the IUCN Red List of Threatened Species and considered how the SPS conservation tool might be utilised in the future to safeguard Antarctic biodiversity. Consideration of SPS designation for the macaroni penguin <em>Eudyptes chrysolophus</em> population within the Antarctic Treaty area might be appropriate. However, the emperor penguin <em>Aptenodytes forsteri</em> should remain a priority for SPS designation in order to minimise further anthropogenic pressures on this climate change-vulnerable species.</div></div>","PeriodicalId":55375,"journal":{"name":"Biological Conservation","volume":null,"pages":null},"PeriodicalIF":4.9,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142560799","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}

Bats—a remarkably rich and diverse group—use habitat from fine (< 0.5 km) to broad (> 4 km) scales, and thus identifying their responses to changing landscapes can highlight a variety of management implications. We conducted a literature review of >170 peer-reviewed studies from five continents of landscape-scale studies in bats. We used cluster analysis to highlight study trends and identify biases and knowledge gaps in landscape-scale studies of bats. Species in the families Vespertilionidae and Phyllostomidae, which represent 51 % of extant bat diversity, were the focus of two thirds of studies; other families were underrepresented. Tropical and subtropical Africa and Asia, notable for their high bat species richness, were underrepresented in studies. Although considered by few studies, context-dependent demographic data, including temporal and behavioral parameters (e.g., age, season) were important for explaining bat-landscape interactions. No one-size-fits-all set of variables or scales exists for bats, and even closely related species vary in their responses to variable-scale combinations. However, variables that quantify habitat size and presence of patch edges were often strong predictors of bat use. Based on this review, researchers should consider a range of scales including broad scales (>5 km), landscape and bioclimatic variables, and archiving data for future studies across temporal scales. We provide a list of recommendations that can help researchers and conservationists improve inferences in determining the landscape associations of bats species and other taxa.</div></div>","PeriodicalId":55375,"journal":{"name":"Biological Conservation","volume":null,"pages":null},"PeriodicalIF":4.9,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142572568","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}

Focusing on the Italian peninsula inside the Mediterranean global biodiversity hotspot, we (i) investigated the patterns of genetic diversity of endemic terrestrial vertebrates, (ii) assessed how much genetic diversity is currently covered by protected areas considering both nuclear and mitochondrial DNA, and (iii) estimated the impact of projected range shifts caused by climate changes on the conservation of genetic diversity patterns. We found that protected areas cover <20 % of the areas of high genetic diversity for most of the investigated taxa, and fail to cover almost all multispecies genetic diversity hotspots. Furthermore, our results showed that mitochondrial DNA is not a reliable proxy for nuclear genome diversity, and its use in spatial conservation planning might lead to ineffective initiatives. Finally, we estimated that the extent of genetic diversity covered by protected areas will dramatically decline in the near future (2050).

Baited tubes were deployed to monitor the presence/absence of shrews by collecting their scats in lakes with and without fish in the western Italian Alps. Only two species, the Valais shrew (<em>Sorex antinorii</em>) and the Eurasian water shrew (<em>Neomys fodiens</em>), were found inhabiting the lakes' edges, where they fed on aquatic insect subsidies. The results indicate a significant pattern of exclusion between shrews and introduced fish. This negative association was especially evident in the presence of large-bodied fish (i.e., salmonids), but also of small fish (i.e., cyprinids). Consistently, compared to naturally fishless lakes, those with fish exhibit a lower availability of aquatic prey, representing a significant portion of the diet of both shrew species. Overall, our findings suggest that the impact on shrews may be mediated by a complex interplay of competition and predation between fish and shrews. Fish impacts may extend beyond the lakes to insectivorous mammals in surrounding areas.

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.

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.

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.

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.
