We conducted vegetation surveys and examined incidental encounter data of a variety of snake and game bird species on a managed pine barren in Montague, MA, from 2008 to 2018. We recorded 73 observations, including 44 Coluber constrictor constrictor (Northern Black Racer) and 7 Meleagris gallopavo (Wild Turkey) nests. All of our observations were in managed habitats (Scrub Oak, treated Pitch Pine, and powerline corridors) which had low (<30%) tree canopy cover. Observed densities of Northern Black Racers did not significantly vary among these open-canopy habitats, or with time since treatment between 2 to 8 years since initial harvest in treated Pitch Pine. We did not conduct extensive surveys in unmanaged, closed-canopy Pitch Pine forests; thus, we were unable to determine the relative use by racers and game birds of unmanaged versus managed habitats. Nevertheless, snakes and game birds were using and nesting in the managed habitats at least to some extent. Our findings on racers and game birds from this study are preliminary, but combined with results from other studies, they suggest that ecosystem management in pine barrens can benefit snakes and game birds, along with a wide variety of other taxa.","PeriodicalId":49742,"journal":{"name":"Northeastern Naturalist","volume":"29 1","pages":"11 - 27"},"PeriodicalIF":0.4,"publicationDate":"2022-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46634949","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}

Global climate models (GCMs) indicate that winters will continue to warm and lose snow in the future, but uncertainty remains regarding the magnitude of warming. Here, we project future trends in winter indicators under lower and higher climate-warming scenarios based on emission levels across northeastern North America at a fine spatial scale (1/16°) relevant to climate-related decision making. Under both climate scenarios, winters continue to warm with coincident increases in days above freezing, decreases in days with snow cover, and fewer nights below freezing. Deep snow-packs become increasingly short-lived, decreasing from a historical baseline of 2 months of subnivium habitat to <1 month under the warmer, higher-emissions climate scenario. Warmer winter temperatures allow invasive pests such as Adelges tsugae (Hemlock Woolly Adelgid) and Dendroctonus frontalis (Southern Pine Beetle) to expand their range north-ward due to reduced overwinter mortality. The higher elevations remain more resilient to winter warming compared to more southerly and coastal regions. Decreases in natural snowpack and warmer temperatures point toward a need for adaptation and mitigation in the multi-million-dollar winter-recreation and forest-management economies.","PeriodicalId":49742,"journal":{"name":"Northeastern Naturalist","volume":"1 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48303839","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}

The mountain regions of Maine, the rest of northern New England and New York’s Adirondacks, and eastern Canada (Fig. 1) are within a day’s drive of the largest metropolitan areas in the US and Canada, yet are recognized as being largely unfragmented and intact. Many mountain ecosystems are protected from local pressures such as human development, agriculture, and other anthropogenic change via conservation efforts or de facto due to inaccessible terrain, but other stressors such as climate change are affecting these fragile and unique systems. The northeastern US is warming faster than most other regions of the world, and these trends are projected to continue (Karmalkar and Bradley 2018). Although detailed data are lacking from Maine’s mountains, research has shown that midto high-elevation areas, as well as more northerly regions, are experiencing the largest climate changes (Pepin et al. 2015). These changes are affecting biodiversity and ecosystem services at all levels (Weiskopf et al. 2020). Thus, mountain ecosystems are of great interest for scientific research that tests hypotheses about species interactions, landscape ecology, physical processes (hydrology, geochemistry), climate-change refugia and tipping points, and physiological response of biota in an extreme environment. These issues were explored in several regional events over the past 5 decades. On April 29, 1972, the first Maine Mountain Conference convened in Augusta, ME, “for the purpose of discussing the nature of the Maine mountain environment and also the present and future uses of these areas” (Maine Mountain Committee 1972).","PeriodicalId":49742,"journal":{"name":"Northeastern Naturalist","volume":"28 1","pages":"ii - ix"},"PeriodicalIF":0.4,"publicationDate":"2022-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47939985","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}
