In the absence of immigration, founder effects, inbreeding and genetic drift are likely to contribute to local extinction risk. Management actions may also have a greater impact on small, closed populations. The demographic and social characteristics of a species can, however, delay the impact of threats. K’gari, a ~ 1 660 km² island off the Australian east coast and UNESCO World Heritage Site (Fraser Island 1842–2023), supports an isolated population of approximately 70–200 dingoes that represent an ideal opportunity to explore the small island paradigm. To examine temporal and spatial patterns of genetic diversity in this population we analysed single nucleotide polymorphism (SNP) genotype data (72 454 SNPS) for 112 K’gari dingoes collected over a 25-year period (1996 to 2020). Genetic diversity was lower in K’gari dingoes than mainland dingoes at the earliest time point in our study and declined significantly following a management cull in 2001. We did not find any spatial genetic patterns on the island, suggesting high levels of genetic connectivity between socially discrete packs. This connectivity, combined with the social structure and behaviour of dingoes, may act in concert to buffer the population from the impacts of genetic drift in the short term. Nevertheless, a general decline in genetic variation via inbreeding and drift has occurred over the past 20 years which we suggest should be considered in any future management planning for the population. Monitoring patterns of genetic variation, together with a clearer understanding of the social ecology of K’gari dingoes, will aid in the development of measurable genetic targets set over ecologically meaningful timelines, and help ensure continued survival of this culturally important population.</p>","PeriodicalId":55212,"journal":{"name":"Conservation Genetics","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140624620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Although both species are emergent, obvious and charismatic elements of the Antillean flora, they were only described within the last decade. <i>Sabal lougheediana</i> is in demographic crisis as a result of constant ungulate pressure prohibiting seedling establishment, while <i>S. antillensis</i> is thriving as a result of careful management. Given the surprisingly recent discovery of these two species, and the severity of the conservation concern, genomic data can help inform whether these taxa are in fact well-circumscribed species, and help to guide further conservation actions. To investigate genomic diversity, we employed RADSeq data from samples throughout the range of both species. Results show significant genetic distance and fixation between the two taxa as currently circumscribed, as well as reduced genetic diversity and increased inbreeding in both species. Multivariate analysis of genetic distance and Bayesian clustering analysis both show clear and significant separation of the two taxa. Parallel assay of ex situ collections informs how future development of germplasm reserves can help support conservation of both species. We provide recommendations to help conserve these two unique and distinct species.</p>","PeriodicalId":55212,"journal":{"name":"Conservation Genetics","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140624661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Habitat loss and fragmentation can be reflected in the patterns of genetic variation in the populations. White-lipped peccaries (WLPs, <i>Tayassu pecari</i>) are wide-ranging Neotropical ungulates with important ecological roles in the ecosystem suffering local extinctions worldwide. Here, we used a RAD-seq protocol to genotype 192 individuals. After filtering, we identified sets of SNP markers (ranging from 147 to 151,792 SNPs) to assess the genetic diversity and population structure of WLPs from Pantanal, Cerrado, and Atlantic Forest in Brazil. We found signals of loss (θw &lt; θπ) and lower genetic diversity (allelic richness, nucleotide diversity, and observed and expected heterozygosities) in the Central Cerrado and Atlantic Forest populations. Principal Component Analysis (PCA) and admixture analyses (NGSAdmix) using genome-wide and neutral SNP data sets showed three major genetic clusters according to the biomes. Multiple matrix regression with randomization (MMRR) analysis found an isolation-by-distance pattern explaining the neutral genetic differentiation. We used Latent Factor Mixed Models (LFMM) and Redundancy Analysis (RDA) to identify candidate SNPs involved in different biological processes, such as metabolism and immune and neuronal responses, mainly associated with temperature and precipitation variables. We found an adaptive population genetic structure, suggesting three adaptive units with significant patterns of isolation-by-distance and isolation-by-environment. Our results highlighted the importance of conservation strategies for maintaining the genetic diversity of WLP populations. Furthermore, conservation plans and translocation programs should preserve and consider the adaptive variation.</p>","PeriodicalId":55212,"journal":{"name":"Conservation Genetics","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140595633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Environmental DNA (eDNA) approaches can enhance the detection power of traditional biomonitoring methods for low-density, newly-established populations. In this study, we used species-specific Real Time PCR TaqMan assays to assess the presence of two endangered freshwater species, the white-clawed crayfish <i>Austropotamobius pallipes</i> and the Eurasian otter <i>Lutra lutra</i> at eight sites in four river catchments in Liguria (northwestern Italy). The Eurasian otter was considered extinct in the study area since the 1980s. However, recent, although scattered sightings indicated a recolonisation by a few individuals. The white-clawed crayfish populations declined drastically and became increasingly dispersed in the western part of Liguria. Our eDNA analysis confirmed the presence of both species in some of the selected rivers and detected Eurasian otter DNA where the species was not recorded through traditional monitoring methods.
