We quantified breeding-season home-range attributes and habitat selection of adult Great Gray Owls across multiple spatial (home-range and within-home-range level) and temporal (nesting and post-fledging; day versus night) scales in western Wyoming, USA. In 2018 and 2019 we outfitted adult male owls (n = 18) with GPS remote-download transmitters and collected hourly location data throughout the breeding season (1 May – 15 September). Using 50% and 95% kernel density estimates (KDE), mean core area was 1.2 km2 and mean home-range size was 6.2 km2 (n = 16). Resource selection analyses incorporated both remotely-sensed and microsite data. We conducted microsite surveys at used and available points within 95% KDE home ranges using a stratified random sample design (n = 661). Determining home-range and breeding habitat requirements will improve density estimates and facilitate the effective management of Great Gray Owls and their habitat. We found differing patterns between habitat selection at the home-range and within-home-range scales. \u0000 \u0000Featured photo by YNP on Flickr. https://flic.kr/p/SA17KT","PeriodicalId":217302,"journal":{"name":"The UW National Parks Service Research Station Annual Reports","volume":"359 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116518280","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}

Envisioning these forbidding regions occupied by humans in prehistory has drawn academic and public audiences alike. The history of these alpine regions is being rewritten the world over, due in part to recent archaeological discoveries made in the alpine regions of the Greater Yellowstone Ecosystem (GYE). These discoveries, some in the wilderness areas of Montana, have revealed a complex tapestry of prehistoric lifeways. Archaeological and paleobiological research in Montana’s GYE alpine regions by Dr. Craig Lee (INSTAAR/ PCRG), Dr. Rachel Reckin (USFS) and Scott Dersam (PCRG) have spearheaded these continued multi-disciplinary studies in the region. Their efforts have focused on the climatological, ecological, as well as cultural impacts of ice patch use and alpine habitation on patterns of prehistoric occupation in the region. The UW-NPS Research Station Small Grant funded archaeological research and reconnaissance of the alpine regions of Montana’s Beartooth wilderness during the summer 2019. The 2019-field season’s discoveries added significant knowledge to regional research in high elevation studies, documenting the highest known stone circles, ceramics, and Paleoindian hunting activities in Montana. \u0000 \u0000Featured photo from figure 4 in report.

Grand Teton National Park biologists have identified this topic (“effect of earlier plant flowering on pollinators and wildlife”) as one of their priority research needs. To address this, we assembled phenological observations of first flowering dates for 48 species collected by Frank Craighead, Jr. in the 1970 and 80s. We hypothesized many species would be flowering earlier now. In 2016 we began standardized observations in the same locations targeting the same species plus 62 for a total of 110. We compare four years of contemporary to historic observations to demonstrate shifts in phenology, and use local weather data to identify the key climatic drivers. The largest effect is observed in early spring flowers, which are blooming ~17 days earlier. Mid-summer flowers bloom ~12 days earlier, and berries bloom ~7 days earlier. Not all species are emerging earlier, particularly late summer flowering plants. Also individual species within these functional groups differ in their responses. The greatest drivers of early spring and mid-summer flowering are average spring temperature (March, April, May) and the day of snow melt timing. Late summer flowers respond more to the accumulation of Growing Degree Days. \u0000 \u0000Featured photo by Shawna Wolf, taken from the AMK Ranch photo collection.","PeriodicalId":217302,"journal":{"name":"The UW National Parks Service Research Station Annual Reports","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123206216","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}

After being functionally extirpated from the United States by the early 1900s, wolves have recently recolonized portions of their historic ranges and are increasingly coming into contact with a rapidly-growing human population. When carnivores encounter humans, the way they behave, and therefore the way they shape ecosystems, is likely to change. Unfortunately, our ability to predict how wolves will affect ecosystems in human-dominated areas is limited by an incomplete understanding of how and why carnivores respond to human influence. We are therefore investigating wolf kill sites across Jackson Hole, Wyoming, where we can disentangle the effects of multiple simultaneous human influences. Specifically, we are evaluating whether and how spatiotemporal patterns of wolf predation may change in response to unnatural physical infrastructure, disturbance from general human activity, potential threat of mortality, and human-altered prey distributions. Our ongoing field study will help managers anticipate effects of wolf predation in and around human-influenced areas while contributing novel information to theories of predation risk and predator-prey interactions. \u0000 \u0000Featured photo by YNP on Flickr. https://flic.kr/p/HGfKqs","PeriodicalId":217302,"journal":{"name":"The UW National Parks Service Research Station Annual Reports","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129700738","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}

Despite this, concerns exist regarding the presence of for-profit entities within national parks. While private businesses may be more responsive to consumers, their presence raises questions regarding equity, access, and perceptions of ownership. The purpose of this study was to assess factors that may influence visitor’s perceptions of appropriateness regarding (a) current and (b) future concessioner activities within Grand Teton National park (GTNP). Regression analyses indicate the importance of personal values, rather than actual experiences (positive or negative) with concessions in shaping perceived appropriateness of future concessions activity. Satisfaction with concessions services, amount of concessions activity that respondents perceived in the park in the present, and trust in GTNP were all non-factors in determining anticipated future appropriateness. Instead, a belief that concessions activity would increase, social liberalism, economic conservatism, and place identity with GTNP were related to perceptions that concessioner activity at GTNP would be inappropriately high in the future. Although the regression predicting future beliefs was robust (R2 = 0.43), no variables significantly predicted current beliefs (R2 = 0.05). \u0000 \u0000Featured photo by Grand Teton on Flickr. https://flic.kr/p/2jf3fa9","PeriodicalId":217302,"journal":{"name":"The UW National Parks Service Research Station Annual Reports","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128983503","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, despite two decades of research, there is still debate as to whether wolves (Canis lupus) have indirectly benefited aspen (Populus tremuloides) by reducing herbivory from elk (Cervus canadensis). As such, the purpose of this study was to investigate the role of top-down and bottom-up forces on aspen recruitment in northern Yellowstone. The UW-NPS grant funds were used to conduct a genetic analysis of 59 aspen stands in an effort to determine whether genetic variation is one control of aspen recruitment. During summer 2018, 122 leaves were collected and sent to the Mock Lab at Utah State University. The samples will undergo DNA extractions at 12 microsatellite loci, which will provide us with genotype and ploidy level, with the genotype at a resolution to distinguish clones. Concurrently, we measured aspen heights and browse rates, as well as soil moisture. The median aspen height in 2018 was 110 cm (SD=135), and the browse rate was 0.45. Stands varied in volumetric water content (VWC), ranging from a mean VWC of 2.7% to 45.2%. \u0000 \u0000Featured photo by Yellowstone National Park on Flickr. https://flic.kr/p/efXLV2","PeriodicalId":217302,"journal":{"name":"The UW National Parks Service Research Station Annual Reports","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124728514","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}

Similarly, nocturnal insects are disproportionately attracted to night lighting, trapping them until they die of exhaustion. The advent of new lighting technology which may decrease the impacts of night lighting on bats and insects by primarily producing light at wavelengths these animals are not sensitive to (i.e. in the red portion of the spectrum) is promising, however no studies have shown this at a large scale, and not in North America. Similarly, many studies on the effects of lights on bats, in general, have been on European species, and thus our overall understanding of how North American species are affected is low. Grand Teton National Park, Wyoming, provides an excellent natural system to study the effects of lights on bat behavior, as well as to test possible mitigation methods, as the park supports a large community of over a dozen species, as well as sizeable human infrastructure that generates night light. From June through September, 2019, we undertook a large-scale, blocked experiment examining bat activity and space use in Colter Bay Village under both traditional street-lighting, as well as new “bat friendly” street lighting. Using both passive echolocation records and radiotelemetry, we collected data that will allow us to examine the ability of red LED streetlights to mitigate artificial light’s negative impacts on bats and insects. \u0000 \u0000Featured photo from figure 2 in report.","PeriodicalId":217302,"journal":{"name":"The UW National Parks Service Research Station Annual Reports","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127302264","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}
