Abstract - Etheostoma punctulatum (Stippled Darter) was recently redescribed to recognize 2 additional species, E. autumnale (Autumn Darter) and E. mihileze (Sunburst Darter), as part of the E. punctulatum species complex. 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.
摘要--Etheostoma punctulatum（条纹箭鱼）最近被重新描述，将另外 2 个物种 E. autumnale（秋箭鱼）和 E. mihileze（旭日箭鱼）认定为 E. punctulatum 种群的一部分。由于阿肯色技术鱼类保藏中心（ATFC）所保藏的条纹镖鱼标本是在重新描述之前和之后采集的，因此这次分类学更新使得阿肯色技术鱼类保藏中心（ATFC）所保藏的条纹镖鱼标本不准确。经过重新评估，我们发现 ATFC 中并不包含任何现在被认为是条纹镖鱼的标本，而是包含了 2 个新描述的物种和被误认为是 Nothonotus juliae（Yoke Darter）的标本。我们的结论是，采集到的标本包括 54 条秋短吻鳄、96 条旭日短吻鳄和 220 条轭短吻鳄。此外，外部的定量和定性特征并不完全符合描述该新物种的研究中提出的预期趋势。这项研究是一个很小但很明显的例子，说明了整理和更新像 ATFC 这样的自然历史藏品的重要性，因为它们在生物地理范围变化、物候变化、进化变化等多个不同的研究领域发挥着至关重要的作用。

Abstract - Etheostoma striatulum (Striated Darter) is an increasingly rare darter found in the middle-to-upper regions of the Duck River watershed in Tennessee. 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.

Abstract - The Fungal, Lichen, and Myxomycete Collections of the University of North Carolina (UNC) at Chapel Hill Herbarium (NCU) contain 952 type specimens, representing 607 names, which, based on current taxonomy and nomenclature, amount to 596 unique taxa. 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.
摘要 - 北卡罗来纳大学（UNC）教堂山标本馆（NCU）的真菌、地衣和粘菌收藏有 952 个模式标本，代表 607 个名称，根据目前的分类法和命名法，相当于 596 个独特的分类群。这些丰富的模式标本是 William C. Coker、Alma Holland Beers、John N. Couch 和其他 UNC 真菌学家在 20 世纪上半叶对真菌进行分类研究的成果。本目录是这些类型标本的汇编，另外还收录了那些曾研究过这些标本的真菌学家打算作为类型标本的无效出版名称标本。此外，还收录了打算作为无效出版物中分类群类型的原始材料标本，这些标本没有被后来验证分类群的作者收录在出版物中。在北卡罗来纳大学保藏的真菌类型中，牛肝菌、棒状真菌、石膏样真菌、水螅状真菌和隔膜真菌的代表性尤为突出。已为 Clavaria atroumbrina 指定了一个标准模式。自2014年以来，北卡罗来纳大学向世界各地的机构借出了1000多件藏品，其中包括100多种类型。

-Pinus spp. (pine) forests are common throughout the southeastern US, and many of these forests are managed to improve habitat for Odocoileus virginianus (White-tailed Deer) and Meleagris gallopavo (Wild Turkey). 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.
