I am a conservation biologist with a focus on vertebrate ecology, and I enjoy working with students and collaborators to employ varied field sampling and modeling techniques to tackle applied ecological questions, both inside and beyond the classroom. My teaching is influenced by a range of research and collaborative projects that emphasize finding solutions to challenges associated with biodiversity loss, habitat loss and fragmentation, and rare species and ecosystem conservation.
Recently, I’ve worked with university, agency, non-profit, and student collaborators to undertake regional, rare wildlife conservation planning efforts in the northeastern U.S., which include field sampling programs to help inform empirically-derived models that can then be used to inform conservation and management decisions at multiple spatial and temporal scales. With a background in Environmental Engineering, I enjoy bringing a quantitative lens to such problems, but I’m most excited about engaging partners from across disciplines to plan and implement conservation actions. Much of my work is focused in New England, but I explore ecological questions across a range of environmental conditions, from alpine systems in Québec and Newfoundland and Labrador, to tropical forest systems on the Yucatán peninsula, with a special focus on evaluating the effects of landscape composition, structure, and change on those systems.
I’m thrilled to be part of AUNE’s interdisciplinary and collaborative Environmental Studies Department where I have the opportunity to engage and learn with students and colleagues from within and beyond the Department and to try to tackle these and other challenging environmental problems inside and outside the classroom. Ecological and environmental systems are so complex that the most effective way to find solutions is to work together, building capacity with a vast array of skills, backgrounds, and perspectives.

I’m interested in a range of varied ecological questions with a particular emphasis on characterizing landscape pattern and evaluating how change in landscape composition and structure affects long-lived systems. I explore these questions through two disparate systems: freshwater turtles and alpine tundra. I work with students and colleagues to design ecological studies and develop empirically-derived models at multiple spatial and temporal scales to inform broad-scale, collaborative conservation planning initiatives, while simultaneously working with collaborators and stakeholders to implements those plans.
Conservation Planning for Blanding’s Turtles in the Northeast U.S.
Northeast Blanding’s Turtle Working Group. The Blanding’s turtle (Emydoidea blandingii) is a long-lived, semi-terrestrial turtle species of conservation concern throughout its range. Several isolated, disjunct populations occur in the northeastern U.S. These populations are limited in extent and occur in some of the most heavily developed parts of the region. Blanding’s turtles are listed as “Endangered” by the IUCN and a Species of Greatest Conservation Need in all five Northeast states in which they occur. Because they require diverse, interconnected wetland and terrestrial habitats across large areas, they are an important umbrella species, and conservation actions targeting Blanding’s turtle likely result in protection of many other species. As part of a regional conservation planning effort (sponsored by the USFWS Competitive SWG program), the Northeast Blanding’s Turtle Working Group developed and implemented a 5-state standardized monitoring protocol and used results to rank sites across the region, develop a “conservation network” of high priority Blanding’s turtle sites, and make management recommendations at the regional and site level. We are currently working to implement that plan. Learn more at: www.blandingsturtle.org

Conservation Planning and Implementation for the Wood Turtle (Glyptemys insculpta) and Associated Riparian Species of Greatest Conservation Need from Maine to Virginia
Wood Turtle Council. The wood turtle (Glyptemys insculpta LeConte) occurs in riverine, riparian, and terrestrial habitats from Nova Scotia to Virginia and west to Minnesota. Recent studies in the northeast region and adjacent Canada have reported population declines as well as elevated adult mortality caused by roadkill and agricultural machinery. Wood turtles have been identified by the Northeast Partners in Amphibian and Reptile Conservation (NEPARC) as a species of regional conservation concern because it is listed in >75% of northeast Wildlife Action Plans, and it is listed as Endangered by the IUCN. Scientists, conservationists, and agency representatives from 13 northeastern states are partnering to identify, protect, manage, and enhance functional riparian and riverine habitats for wildlife throughout the region.

Community-based ecological research and conservation of the Yucatán box turtle in Yucatán, Campeche, and Quintana Roo
The Yucatán box turtle (Terrapene carolina yucatana) is one of the southernmost, disjunct, and isolated representatives of the wide-ranging North American genus Terrapene (New World box turtles). The status of the Yucatán box turtle is believed to be more precarious than most other taxa in the T. carolina complex, because it is heavily collected as a pet, food source, and medicinal item (for the treatment of asthma) across much of its native range. Prescribed burns, deforestation, and habitat loss are additional pressures facing the subspecies, but little is known about its distribution, status, habitat preferences, or behavior. We have been developing long-term partnerships with scientists, land managers, local business owners, residents, teachers, and ranchers across Yucatán to 1) assess the distribution and relative abundance of Yucatán box turtles through surveys and interviews, 2) evaluate movement and behavioral patterns using radio-telemetry, 3) develop methods of population assessment and prioritization, and 4) gradually develop a realistic and collaborative conservation strategy with conservation partners and small villages in the center of the range.

Ecology and Management of the Gulf Coast Box Turtle (Terrapene carolina major)
The Gulf Coast box turtle (Terrapene carolina major Agassiz, 1857) is a medium-sized, semi-terrestrial emydid turtle native to portions of the north shore of Gulf of Mexico from the Panhandle region of Florida to eastern Texas. The T. c. major lineage is considered to be a modern form of the Pleistocene T. c. putnami, which ranged the Gulf Coastal Plain and reached carapace length of 300 mm, and most researchers conclude that the major lineage is an evolutionarily significant one because of the retained putnami traits (such as the plesiomorphic axillary scute and large body size) and semi-aquatic habitat preference. The typical form of the Gulf Coast box turtle is restricted to outlying coastal areas and islands between Gulf County, Florida, and Plaquemines Parish, Louisiana, and relatively little is known of rangewide abundance, local population densities, and individual responses to disturbances such as prescribed burns, which are conducted in slash pine plantation at intervals as frequent as every three years. We have initiated a long-term study of box turtle populations along the Apalachicola River in Gulf, Franklin, and Liberty Counties, Florida, and on offshore islands near the mouth of the Apalachicola River to evaluate the effects of landcover and disturbance frequency on the population structure of Gulf Coast box turtles.

Evaluating Recovery of the Northern Red-bellied Cooter The Massachusetts population of the Northern Red-bellied Cooter (Pseudemys rubriventris), formerly Plymouth Red-bellied Cooter, was listed as an endangered species on April 2, 1980. At the time of listing, cooters in Massachusetts were known from only 12 ponds in Plymouth County, MA, with an estimated population of approximately 200 individuals. To increase survival and recruitment by reducing predation rates, the Massachusetts Division of Fisheries and Wildlife (MADFW), in partnership with the USFWS, began a headstarting program (raising wild hatchlings in captivity for 9 months) that continues today. With UMass Amherst, MADFW, and the USFWS, we are assessing the effectiveness of the head start program, estimating current distribution and population status of the species, and identifying management actions necessary to promote species recovery.

Conservation of Alpine Biodiversity in Eastern North America
With Beyond Ktaadn (www.beyondktaadn.org), a non-profit organization that is committed to the conservation of alpine biodiversity in eastern North America through applied research, educational programs, and strong regional partnerships, I am collaborating with scientists throughout New England, Quebec, and Newfoundland and Labrador, to develop and institute studies and monitoring programs for plants and wildlife species on high elevation, treeless mountain systems across the region. Our work in the region led to a collaborative book, the Eastern Alpine Guide, published in 2012, and we are currently involved in a number of collaborative projects throughout the eastern alpine region which include botanical surveys, mammal community sampling via camera traps, amphibian and avian sampling using acoustic recorders, invertebrate sampling, phylogenetic analyses of plant species, rare plant species recovery efforts, and multi-scale habitat modeling on mountains in New Hampshire, Maine, Québec, and Newfoundland and Labrador. Beyond Ktaadn assisted with a GLORIA installation in the Gaspé region of Québec in 2011, a second installation in the White Mountain National Forest in 2014, and began an installation in the Monts Groulx (Uapishka) in 2010, which we plan to complete in 2015 or 2016. Beyond Ktaadn has a long-term commitment to alpine research and conservation, and as part of that plans to continue to collaborate with partner organizations to institute a network of long-term, low impact alpine biodiversity monitoring studies throughout the region in order to assess the effects of climate and landscape change on these rare and sensitive ecosystem types.
