This taxonomic update rendered the collection of Stippled Darters in the Arkansas Tech Fish Collection (ATFC) inaccurate since the stored specimens were collected well before and just after the redescriptions. Upon reassessment, we found that the ATFC did not contain any specimens now considered as Stippled Darters but, instead, contained specimens of the 2 newly described species and misidentified Nothonotus juliae (Yoke Darter). We concluded that the collection consisted of 54 Autumn Darters, 96 Sunburst Darters, and 220 Yoke Darters. Additionally, external quantitative and qualitative characteristics did not exactly follow the expected trends as laid out in the study that described the new species. This study serves as a small, but clear, example of the importance of curating and updating natural history collections like that of the ATFC, for they play a vital role in a number of different areas of study including biogeographic range changes, phenological shifts, evolutionary changes, and more.","PeriodicalId":49490,"journal":{"name":"Southeastern Naturalist","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141685737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

This rarity, coupled with a lack of collection and sampling, has put them in review for listing under the Endangered Species Act. Because of the Striated Darters' reclusive and cryptic behavior, conventional techniques tend to be less effective for detection, requiring more precise and sensitive methods. To provide information regarding distribution and occupancy within the Duck River, we used molecular detection of species-specific environmental DNA to test for presence of the species at historical sampling sites. Assessments indicate that Striated Darter is persisting in all tributaries of historical occurrence, with the addition of 4 new tributaries. However, given that 16 sites produced positive signals for less than a third of qPCR replicates, it appears that 60% of these populations are persisting at low detection levels. Detection was positively correlated with turbidity, which could be explained by their preference for lower-velocity habitats. Our results will assist with identifying critical-habitat locations for the update on the status of Striated Darter while also aiding in the standardization of eDNA-assay development for rare and cryptic species.","PeriodicalId":49490,"journal":{"name":"Southeastern Naturalist","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141687109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

This wealth of type specimens is a legacy of the taxonomic research on fungi conducted by William C. Coker, Alma Holland Beers, John N. Couch, and other UNC mycologists in the first half of the 20th century. This inventory is a compilation of these types plus specimens for invalidly published designations that were intended as types by the mycologists who worked on these specimens. Also included are original material specimens intended as types for taxa in invalid publications, which were not included in the publications by subsequent authors validating the taxa. Fungal groups particularly well represented in the types held at NCU are boletes, clavarioid fungi, gasteroid fungi, hydnoid fungi, and septobasidia. A lectotype is designated for Clavaria atroumbrina. Since 2014, more than 1000 collections including >100 types have been loaned by NCU to mycologists at institutions around the world.","PeriodicalId":49490,"journal":{"name":"Southeastern Naturalist","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141684955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Previous studies have investigated the influ - ence of forest management on deer and turkey habitat, but several aspects of understory vegetation response to management are not well understood. We measured understory composition and structure, overstory basal area, and deer-forage availability at 8 sites in summer 2020. Previous history of dormant-season fire increased grass and decreased vine coverage, but forb and understory tree coverage were not influenced. Vegetation providing visual obstruction for turkey nesting and deer fawning was correlated with increased coverage of semiwoody and woody plants. Forb coverage averaged 14% and was positively correlated with deer nutritional carrying capacity (NCC) using a 14% protein constraint. Conversely, NCC with a 6% protein constraint correlated with shrub and vine coverage. Sunlight available to the understory was most strongly influenced by hardwood overstory and midstory trees. Our results indicate that understory composition strongly influences forage and cover and that pine stands that are not intensively managed generally provided limited resources for deer and turkeys.","PeriodicalId":49490,"journal":{"name":"Southeastern Naturalist","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141267104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
