Today, however, oak woodlands occupy only a small percentage of their former extent, and so efforts are underway to restore them. This study examined growth of young trees, frequency of acorn production (an index of recruitment potential), and seedling recruitment in two bur oak cohorts, planted in 2007 and 2009, in a mostly unmanaged setting undergoing old field succession. Documenting the variation in growth response is important for predicting rates of establishment and recruitment in woodland restorations where bur oaks are planted with little to no subsequent intervention. Trees grew an average 40.59 cm/year in the 2007 cohort, and 30.49 cm/year in the 2009 cohort. For both cohorts, height was a function of age (2007 cohort: r2 = 0.793; 2009 cohort: r2 = 0.616). In 2022, diameter at breast height (DBH) was a strong predictor of tree height (2007 cohort: r2 = 0.776; 2009 cohort: r2 = 0.927). There was great variation in fruit production among individual trees: annual acorn production varied from ∼1 to ∼45 % of trees in the 2007 cohort and from ∼4 to ∼24 % of trees in the 2009 cohort. In 2022, 81.25 % of randomized 4 m x 4 m quadrats contained bur oak seedlings. It is encouraging that acorn production commenced just a few years after planting and that substantial recruitment from seed began within ten years, suggesting that bur oak stands so established can become self-sustaining. These results can inform restoration ecologists who wish to reestablish native oak stands but may lack the time and resources to provide much follow-up.","PeriodicalId":23234,"journal":{"name":"Transactions of the Kansas Academy of Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139271493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The protection of biodiversity in freshwater environments ensures economically beneficial ecosystem services are maintained. Freshwater ecosystems are hotspots for biodiversity and have higher levels of imperiled organisms compared to terrestrial and marine systems. The objective of this study was to develop an aquatic environmental DNA (eDNA) protocol that increases detection sensitivity to target rare and endangered aquatic organisms in Kansas. The Cylindrical Papershell mussel (Anodontoides ferussacianus) was listed as endangered in Kansas in 2019 and was used for protocol development due to its contracting distribution and low population density. While this species was used in the development of the protocol, the objective of this protocol is not restricted to this species. Following this protocol, Cylindrical Papershell DNA was detected at a sensitivity of 1.7 parts per billion in 1 L of water. Increasing detection sensitivity will be necessary for successful conservation strategies as we proceed through the Anthropocene due to compounding costs associated with monitoring and managing an increasing number of declining populations. This protocol, in conjunction with traditional sampling efforts, will aid in future monitoring and recovery plans of native aquatic species.","PeriodicalId":23234,"journal":{"name":"Transactions of the Kansas Academy of Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139273466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, estimating animal density requires information on the decay rate of dung and the animal's defecation rate. Before the arrival of Europeans, the American Bison (Bison bison) was one of the most widespread megafauna in North America. Yet, we are unaware of any study that has quantified the fundamental measurements of dung decay and deposition rates in bison. This study aimed to determine the dung decay rate and defecation rate of bison to estimate population size and habitat usage. The decay rate of bison dung was tracked by revisiting cohorts of dung piles throughout the year for an average of 184 days using a five-class classification system to track the decay process. Only 23 of our 78 dung piles fully decayed within the 168 to 211 days of tracking, with an average of 101 days for decay, which is substantially slower than similar megafauna, such as cattle and cape buffalo. However, using a decay class system instead of full decay is useful in tracking bison habitat usage because dung transitions to class 4 over a consistent 25 to 30 days. Based on video recordings in autumn, the average defecation rate of bison was calculated to be approximately 10.7 dung piles per animal per day. These results can be used to track bison habitat usage in grassland ecosystems, with especially high accuracy of usage in the last 30 days.","PeriodicalId":23234,"journal":{"name":"Transactions of the Kansas Academy of Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139271894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
