Numerous studies have investigated the effects of infestation on benthic communities; however, because Zebra Mussels were already established within these systems, it is possible that results were influenced by ecosystem-wide changes in water clarity and suspended nutrient concentrations. In this study, we placed tiles with artificial Zebra Mussel druses in Lake Bemidji, which did not have a well-established Zebra Mussel population at that time, to investigate the effects of benthic habitat modification on macroinvertebrate communities and carbon accumulation. We used control (n = 0 druses) tiles as well as 3 treatment tiles—low (n = 247), medium (n = 428), or high (n = 610) number of individuals per tile—to examine how Zebra Mussel density affected macroinvertebrate communities and carbon accumulation. Macroinvertebrate abundance (ANOVA: P < 0.001) was higher on the treatments compared to the control tiles. However, macroinvertebrate density was highest on control tiles (one-way test: P = 0.002), and treatment did not influence overall community structure (NMDS: P = 0.111) or macroinvertebrate diversity (ANOVA: P = 0.630). Furthermore, organic matter ash-free dry mass (AFDM) density was highest on control tiles (one-way test: P = 0.021), while treatment did not influence invertebrate AFDM density (one-way test: P = 0.098). These results indicate that while macroinvertebrates are able to exploit the additional habitat provided by druses, biological processes such as water filtration, carbon transfer, and benthification facilitated by living Zebra Mussels were also likely crucial in restructuring benthic communities to the extent observed in previous studies.","PeriodicalId":49742,"journal":{"name":"Northeastern Naturalist","volume":"30 1","pages":"347 - 367"},"PeriodicalIF":0.4,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43774213","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}

Our objective was to examine differences in relative behavioral frequencies between the forested and urban habitat. Using focal-animal sampling techniques, we observed 17 distinct behaviors. Four behaviors showed significant difference between habitats: pause, vertical pause, forage, run. We attribute these differences to the characteristics of the landscape. Pause and vertical pause occurred in the urban habitat more often than expected, most likely due to the openness and lack of protection from predators overhead. Foraging was more frequent within the urban habitat, perhaps due to greater variety, distribution, and availability of anthropogenic food sources. Run behavior was less prevalent in the urban habitat, likely because chipmunks and other animals have become accustomed to human presence. Our work supports findings by others that indicate wildlife that persist in human-modified environments display behavioral differences influenced by habitat.","PeriodicalId":49742,"journal":{"name":"Northeastern Naturalist","volume":"30 1","pages":"295 - 303"},"PeriodicalIF":0.4,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46810939","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}

Furthermore, the sensitivity of this forest-type to changes in climate and pollution exposure is unknown. We collected xylem increment cores from 4 conifer species (Thuja occidentalis [Northern White Cedar], Juniperus virginiana [Eastern Red Cedar], Pinus strobus [Eastern White Pine], and Tsuga canadensis [Eastern Hemlock]) and 4 hardwood species (Quercus rubrum [Northern Red Oak], Quercus alba [White Oak], Fagus grandifolia [American Beech], and Fraxinus americana [White Ash]) within and close to a cedar–pine forest along the eastern shore of Lake Champlain in Vermont and correlated radial tree growth to precipitation, snow, temperature, and pollution data to assess which factors influenced growth during the time period 1937–2016. We examined growth and possible environmental drivers of it for a variety of species to evaluate how unique these may be for the cedar and pine trees emblematic of the limestone-bluff community. For both conifers and hardwoods, precipitation exhibited the strongest positive correlations with growth and occurred with greater frequency compared to other climate and pollution parameters. Snow was positively associated and temperature was negatively associated with growth for all species. Despite growing over calcium-rich bedrock, and especially for the conifers, pollution seemed to limit growth in years prior to pollution reductions enacted following the 1990 Amendments to the Clean Air Act.","PeriodicalId":49742,"journal":{"name":"Northeastern Naturalist","volume":"30 1","pages":"244 - 268"},"PeriodicalIF":0.4,"publicationDate":"2023-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48677329","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}

On Mount Desert Island, ME, a population of Spotted Salamanders breed in an aggregation of pools located atop a coastal rock cliff that is subject to seawater intrusion from nearby wave action. We periodically measured salinity concentrations (in ppt) of 7 pools with the highest breeding activity from 2016 to 2021 to quantify pool salinities within and between 5 breeding seasons. Our findings confirm that this breeding habitat experiences sporadic and extreme bouts of salt intrusion from the adjacent ocean, causing salinity levels to vary markedly and unpredictably (0.1 ppt to 32.5 ppt) on a spatiotemporal scale. The presence of salamanders exhibiting apparent normal behavior in salinities greater than 12 ppt suggest an upper threshold of salt tolerance in this population that exceeds purported upper thresholds for the majority of amphibians studied to date. Future experimental work on this population holds great promise to deepen our understanding of the underlying mechanisms of salt tolerance in coastal populations of amphibians from both a physiological and evolutionary perspective.","PeriodicalId":49742,"journal":{"name":"Northeastern Naturalist","volume":"30 1","pages":"212 - 225"},"PeriodicalIF":0.4,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42045563","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}
