Previous crosses among 20 populations of <i>Gymnadenia conopsea</i> documented the strongest heterosis and the weakest inbreeding depression in sparse and small populations, consistent with fixation of mildly deleterious alleles by genetic drift. We genotyped the populations used for crosses, and used 1200–1728 SNPs to test the following predictions: (1) heterosis increases with genetic differentiation (<i>F</i>_<i>ST</i>) to donor populations and decreases with genetic diversity in the recipient population, (2) inbreeding depression increases with genetic diversity, and (3) genetic diversity increases, and mean <i>F</i>_<i>ST</i> to other populations decreases, with population size and density. Pairwise <i>F</i>_<i>ST</i> ranged from very low to moderate (0.005–0.20) and genetic diversity varied moderately among populations (proportion of polymorphic loci = 0.52–0.75). However, neither <i>F</i>_<i>ST</i> between populations, nor genetic diversity in the recipient population, were related to the strength of heterosis. There was also no association between genetic diversity and the strength of inbreeding depression. Genetic diversity increased and mean <i>F</i>_<i>ST</i> decreased with population size, consistent with reduced diversity and increased differentiation of small populations by genetic drift. The results indicate that the loci conferring heterosis are not mirrored by overall population differentiation, and limited additional information on potential source populations for genetic rescue is gained by the genetic data. Instead, the use of controlled crosses can directly reveal positive effects of introducing new genetic material, and is a simple method with high potential in conservation.</p>","PeriodicalId":55212,"journal":{"name":"Conservation Genetics","volume":"18 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142263030","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}

The Shawnee Hills Cavefish is hypothesized to be restricted to Illinois, Missouri, Kentucky and north-central Tennessee, whereas the Spring Cavefish is restricted to the Eastern Highland Rim of central Tennessee.

Our results corroborate the recognition and hypothesized distributions of the Shawnee Hills Cavefish and Spring Cavefish. Furthermore, we suggest the recognition of three Evolutionary Significant Units (ESUs) and two Management Units (MUs) within the Shawnee Hills Cavefish.

By combining perspectives from these entities with comprehensive literature review, we identified five guiding principles for conservation genetic and genomic research and explored the different elements of, and approaches to, collaboration. Our reflections suggest that there is a substantial overlap in research interests across the Australian conservation sector, and our findings show that collaboration is increasing. We discuss approaches to building collaborative partnerships, the reciprocal benefits of collaborating, and some remaining challenges associated with data generation, data collection, and cross-cultural considerations. We emphasise the need for long-term national resourcing for sample and data storage and consistency in collecting, generating and reporting genetic data.

Small and isolated populations have elevated risk of extinction due to demographic and genetic stochasticity. The Apostle Islands National Lakeshore features a genetically unique and culturally important population of archipelagic black bears (<i>Makwa; Ursus americanus</i>). While dispersal is central to population viability, previous studies of this population did not sample the adjacent mainland black bear population on the Red Cliff Reservation (<i>Gaa-miskwaabikaang</i>). Therefore, we lack robust estimates of dispersal, gene flow and overall connectivity among the islands and with the mainland population. In partnership with Red Cliff Band of Lake Superior Chippewa and the National Park Service, we non-invasively collected black bear hair, and used 17 microsatellite markers to genotype 141 black bears. We then estimated genetic diversity, population structure, dispersal, and conducted a pedigree network analysis to identify areas of the archipelago important for connectivity and reproduction. We found evidence of a well-connected archipelagic bear population structured into five clusters and characterized by moderate dispersal between islands and mainland. We found that three of the islands are disproportionately important for genetically connecting the archipelago, but the islands were nevertheless reliant upon the mainland for gene flow and genetic diversity. The high connectivity between islands and the mainland demonstrates a potential metapopulation dynamic, where islands may serve as a reservoir of individuals for the mainland and the mainland supplying individuals likely important for maintaining genetic diversity of island populations. Given the importance of island–mainland connectivity, future tribal and federal collaboration will be important to maintain a genetically and demographically viable population of black bears.</p>","PeriodicalId":55212,"journal":{"name":"Conservation Genetics","volume":"175 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142208226","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}

Four previously documented mtDNA haplotypes were identified: SI1 and ECI each had a single haplotype (BN and BL, respectively), while SI2 had two haplotypes (BA and BF). The mtDNA markers indicated substantial genetic differentiation among the populations, while differentiation using microsatellite data was moderate. The populations were assigned to three genetic groups: SI1, SI2, and the ECI. However, 39% of these individuals showed mixed ancestry, indicating ongoing gene flow despite natural and human-made barriers.

Genetic diversity indicators and empirical genetic data can provide different information for conserving genetic diversity. Genetic diversity indicators enable affordable tracking, reporting, prioritization and communication, although, being proxies, do not provide comprehensive evaluation of the genetic status of a species. Conversely, genetic methods offer detailed analysis of the genetic status of a given species or population, although they remain challenging to implement for most species globally, given current capacity and resourcing.

One recipient site, Elephant Mountain Wildlife Management Area (WMA), now the primary source-stock for translocations in Texas, was examined to measure its genomic ancestry compared to other DBS from the Great Basin, Mojave, and Sonoran deserts. Genomic data (5,434–62,749 single nucleotide polymorphisms) were used to estimate kinship, inbreeding, and effective population size across three time periods (2000, 2017, and 2019). Individuals genetically were most similar to DBS from the Gabbs Valley Range and Muddy Mountains, Nevada (Mojave DBS lineage). Strong signatures of inbreeding were not detected among individuals. In addition, genetic pedigree reconstruction revealed familial relationships, including a four-generation pedigree, and indicated 39.51% and 41.89% of individuals translocated in 2017 and 2019, respectively, were parent–offspring or full-sibling pairs, suggesting capture methods tend to sample highly related individuals.
