A novel study in Acadia National Park seeks to help visitors reduce the risk of tickborne disease <\/em><\/p>\n

When UMaine social scientist Sandra De Urioste-Stone<\/a> and her students conducted climate change research in Mount Desert Island\u2019s Acadia National Park (ANP) in 2015-16, many of the park visitors interviewed said one of their greatest concerns for future visits was the perceived threat posed by ticks and the possibility of contracting Lyme disease.<\/p>\n

This in turn led to a new Mitchell Center-funded interdisciplinary project De Urioste-Stone and her colleagues are currently conducting in ANP to develop a model that integrates data from biological, climate, and social science research and will be used to identify ecological and sociocultural factors that influence the risk of human exposure to Lyme disease transmission.<\/p>\n

The model, which could eventually be replicated in other National Parks, would provide park rangers, interpreters, and managers with solid information to share with park visitors that would make them aware of areas of high-risk for tick bites, and help them make informed travel decisions.<\/p>\n

In 2015, the U.S. Centers for Disease Control ranked Maine third in documented incidences of human Lyme disease (only Connecticut and Delaware ranked higher), and outdoor recreation could be adversely impacted as some visitor groups become afraid of activities that may expose them to ticks.<\/p>\n

\u201cWe\u2019re trying to see how we can use a variety of techniques from our different disciplines to integrate biophysical and social science data so it\u2019s comparable and can be used in other park locations,\u201d says De Urioste-Stone, assistant professor of nature-based tourism in the School of Forest Resources and Mitchell Center faculty fellow.<\/p>\n

For the social science component of the project, graduate students Lydia Horne and Alyssa Soucy, and undergraduates Asha DiMatteo-LePape and Hope Kohtala go out weekly and talk to park visitors about their knowledge and risk perceptions about ticks and tickborne diseases and tally where in the park visitors have been and what type of recreation activities they\u2019ve done, such as hiking particular trails. They also ask what kind of protective behaviors visitors practice with tickborne disease in mind, including such actions as using repellents or wearing long pants tucked into socks.<\/p>\n

They conduct what\u2019s called two-stage cluster sampling, meaning they randomly select the dates, times, and locations when they\u2019re in different parts of the park, and once in those locations, they randomly select visitor groups. \u201cThat allows us to make sure we\u2019re randomly selecting participants and are then able to generalize to a larger population of visitors to Acadia National Park,\u201d notes De Urioste-Stone.<\/p>\n

Partnering with De Urioste-Stone is Allison Gardner<\/a>, assistant professor of arthropod vector biology in the School of Biology and Ecology and Mitchell Center faculty fellow who studies the ecology of ticks and mosquitoes. Other team members include Danielle Levesque<\/a>, an assistant professor of mammalogy and mammalian health in the School of Biology and Ecology, and Sean Birkel<\/a>, a research assistant professor in the Climate Change Institute who works on climate modeling.<\/p>\n

\u201cThe main goal of our research is to develop a risk map for exposure to blacklegged ticks (also known as deer ticks) in Acadia, which requires that we identify the factors that affect their distribution,\u201d Gardner says.<\/p>\n

The tick survey component of the study is designed using 20 core sites, the same sites used in the most recent published census of ticks in Acadia 30 years ago. An additional 30 sites were used to collect ticks once in July when the nymphs\u2014 the life-stage that is most likely to transmit infectious diseases to humans\u2014are active. Leading the fieldwork are two of Gardner\u2019s students\u2014master\u2019s student Sara McBride and undergraduate Honors student Lucy Guarnieri. All the ticks collected over the summer will be tested for Borrelia burgdorferi<\/em>, the pathogen that causes Lyme disease.<\/p>\n

The species distribution model will show where in the park ticks would be expected to be found based on such factors as the type of vegetation, local temperatures and the presence of small mammals.<\/p>\n

Referring to potential park visitors, Gardner adds, \u201cIf we can\u00a0provide\u2014and disseminate through trusted sources\u2014accurate information about risk of exposure to ticks and Lyme disease, we hope park visitors will be less likely to make decisions about whether and where to spend time outdoors out of fear or misinformation.\u201d<\/p>\n

Moving beyond Acadia<\/strong><\/p>\n

External partners include ANP, the Maine Medical Center Research Institute, and the National Park Service. Danielle Buttke, one of only two epidemiologists assigned to oversee public health prevention and response in the National Park Service, is a member of the project.<\/p>\n

In her support for the project Buttke writes, \u201c[The work] will be an important step toward developing much-needed public health resources, and the impact would extend far beyond the borders of Acadia National Park as we would distribute the findings of this study and any developed materials to all participating parks and our 330 million visitors.\u201d<\/p>\n

Says De Urioste-Stone, \u201cDanielle is very interested in integrating social science with biophysical data, and is particularly interested in what we can learn from Acadia that could be applicable to other parks.\u201d<\/p>\n

Gardner notes, too, that the impetus for her crossover into the social science realm began when she started attending the weekly Mitchell Center Sustainability Talks<\/a> shortly after arriving from the University of Illinois.<\/p>\n

\u201cMy experience with the Mitchell Center got me interested in conducting interdisciplinary research in teams of natural and social scientists,\u201d she says. \u201cA few years ago, it is not necessarily where I would have envisioned my research moving in my early career, but now all of my projects involve collaborations with social scientists.\u201d<\/p>\n

Other related research on ticks being conducted by UMaine\/Mitchell Center associates<\/strong><\/p>\n

Allison Gardner and Carly Sponarski<\/a>, assistant professor of human dimensions of wildlife and fisheries conservation and Mitchell Center faculty fellow, are part of another UMaine tick project<\/a> that recently received funding from the U.S. Department of Agriculture to develop and test land management practices to protect Maine forest workers from exposure to tickborne diseases.<\/p>\n

Sandra De Urioste-Stone, Pauline Kamath<\/a>, assistant professor of animal health in the School of Food and Agriculture, and Anne Lichtenwalner<\/a>, director of the UMaine Animal Health Laboratory, are part of a research project to study the moose-winter tick system through Interdisciplinary Undergraduate Research Collaborative<\/a> and Research Reinvestment Fund (RRF) Graduate Student grants.<\/p>\n

Gardner, Danielle Levesque, and Sean Birkel are part of an interdisciplinary research project to study the impacts of temperature and snowpack on overwinter survival of blacklegged ticks, supported by an RRF Graduate Student Assistantship grant.<\/p>\n
