Aquatic organisms, such as dragonflies (Odonata), have therefore either had to adapt to disturbed and modified secondary habitats, such as farms, golf courses, storm-water remediation basins, and community-park ponds, or risk extirpation. The species that readily adapt to these habitats are usually widespread common species. However, other aquatic habitats inadvertently created at abandoned work sites often evolve distinctive characteristics over time that provide refuge for species rarely or never found at deliberately created pond habitats. For 17 years, we have monitored the diverse Odonata fauna at several floristically distinct ponds formed in depressions left from the dredging of the Chesapeake and Delaware Canal in the 1960s. Among the species found are ones not known elsewhere locally or ones found in unusual abundance at 1 or more of the ponds, though infrequently encountered regionally. These dredge-spoil ponds are important for conserving regional Odonata biodiversity by providing unique habitats in an increasingly urbanized environment.","PeriodicalId":49742,"journal":{"name":"Northeastern Naturalist","volume":"29 1","pages":"262 - 294"},"PeriodicalIF":0.4,"publicationDate":"2022-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46941275","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}

First detection of individuals tagged in previous years (i.e., returnees) revealed synchronous upstream run timing in both rivers during 2015 and 2018. Greater delays of migrants attempting passage through the periodically submerged tide gate prompted temporary removal of 1 flapper door during 2016–2019 runs. During a 7-day period following door removal, the number of individuals passing per day increased 4- to 6-fold during 2016–2017 and less than 2-fold during 2018–2019. More than 80% of returnees passed the periodically submerged gate following door removal, decreasing mean delay to less than that of migrants attempting passage of the constantly submerged gate. Most individuals passed the periodically submerged gate during mid-flood daily tide phases and none passed during low-tide outflow due to high water velocities. Passage of the constantly submerged gate occurred during all tide phases, with 77% passing during ebb and low tides. The constantly submerged tide gate provided greater windows of opportunity, resulting in relatively shorter delays compared to the periodically submerged tide gate. Long-term monitoring in this study highlighted the effectiveness of temporary and/or adaptive mitigation when addressing issues in river connectivity and fish passage.","PeriodicalId":49742,"journal":{"name":"Northeastern Naturalist","volume":"29 1","pages":"239 - 261"},"PeriodicalIF":0.4,"publicationDate":"2022-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49066073","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}

Commonly, White-Footed Deermice are ecological generalists, and North American Deermice are ecological specialists. In the Inner Bluegrass Region of Kentucky, these 2 species are sympatric in agroecosystems habitats, including the University of Kentucky North Farm. This farm was the most trapped location in central Kentucky from 1950 to 1968, with results indicating the White-Footed Deermoouse was the more common of these species. Trapping from 1995 to 2015 found that North American Deermice were caught rarely. Our study examined agroecosystems habitats at the UK North Farm, including all perennial and annual habitats, to determine the relative abundance and habitat use by both these species. In our study, North American Deermice was the most commonly captured species; it was trapped rarely in perennial habitats but much more frequently in annual crops. Perennial clover fields and Medicago sativa (Alfalfa) were the 2 exceptions; however, these are short crops with exposed soil between rows. Essentially, North American Deermice were observed in the agricultural equivalent of early successional habitat. In contrast, White-Footed Deermice were captured in both perennial and annual habitats, but more commonly in perennial habitats, the exception being annual Salvia hispanica (Chia) fields where dense, green plants produced a thick canopy. Overall, the best predictor of habitat for North American Deermice was bare, exposed soil, whereas the best predictor for White-Footed Deermice was dense growth and overhead cover.","PeriodicalId":49742,"journal":{"name":"Northeastern Naturalist","volume":"29 1","pages":"229 - 238"},"PeriodicalIF":0.4,"publicationDate":"2022-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48688796","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}

Constructed living shoreline marshes can serve as successful management solutions when implemented correctly, but studies comparing these created estuarine habitats to their natural marsh counterparts are needed to assess their ecological functionality. We compared adult Palaemonetes pugio (Daggerblade Grass Shrimp) population demographics and diets from 13 pairs of living shoreline and natural marsh sites in the southwestern portion of the Chesapeake Bay. No significant differences were observed in demographics including abundance, weight, length, number of gravid females, and egg abundance and quality. Gut-content analysis detected significantly more terrestrial debris in shrimp from living shorelines, but the omnivorous dietary needs appeared met in all marsh sites. Overall, shrimp populations differed more among site pairs from different shorescape settings than between created and natural marshes from the same settings, suggesting that living shorelines are approaching ecosystem functionality similar to natural marsh habitats. However, the observed negative effect of agricultural land use on shrimp abundance and the discovery of microplastics in gut contents from all sites sampled indicate the need for further consideration of human impacts in both constructed and natural coastal habitats.","PeriodicalId":49742,"journal":{"name":"Northeastern Naturalist","volume":"29 1","pages":"207 - 228"},"PeriodicalIF":0.4,"publicationDate":"2022-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45324206","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}

We used both field techniques and molecular methods to assess biodiversity in a stream in southwest Virginia. We used emergence traps to collect organisms that emerged from the stream as reproducing adults over a 4-week period and collected environmental samples (e.g., water, sediment) to sequence the DNA found in the samples. Emerging aquatic insect abundance, richness, and diversity increased over time. More family richness was detected using environmental DNA (eDNA) than traditional field sampling; however, many families detected using field techniques were not recovered using eDNA, furthering support that both protocols are necessary for fully documenting biodiversity. We did not have much success in identifying eDNA sequences to species with high sequence similarity, suggesting that invertebrate biodiversity of southwest Virginia is not well-documented in open-source DNA sequence databases. In addition to documenting insect biodiversity, we measured the levels of heavy metals in the stream sediment. Sediment values for cadmium, chromium, copper, mercury and lead were within regulatory limits and were not significantly correlated with biodiversity measures.","PeriodicalId":49742,"journal":{"name":"Northeastern Naturalist","volume":"29 1","pages":"171 - 197"},"PeriodicalIF":0.4,"publicationDate":"2022-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43934795","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}
