Introduced invasive pests are perhaps the most important and persistent catalyst for changes in forest composition. Infestation and outbreak of the hemlock woolly adelgid (Adelges tsugae; HWA) along the eastern coast of the USA, has led to widespread loss of hemlock (Tsuga canadensis (L.) Carr.), and a shift in tree species composition toward hardwood stands. Developing an understanding of the geographic distribution of individual species can inform conservation practices that seek to maintain functional capabilities of ecosystems. Modeling is necessary for understanding changes in forest composition, and subsequent changes in biodiversity, and one that can be implemented at the species …

Evaluation Of A Waistband For Attaching External Radiotransmitters To Anurans, Luke Alexander Groff, Amber Pitt, Robert Baldwin, Aram J K Calhoun, Cynthia Loftin Jul 2015

Evaluation Of A Waistband For Attaching External Radiotransmitters To Anurans, Luke Alexander Groff, Amber Pitt, Robert Baldwin, Aram J K Calhoun, Cynthia Loftin

Publications

Radiotelemetry provides fine-scale temporal and spatial information about an individual's movements and habitat use; however, its use for monitoring amphibians has been restricted by transmitter mass and lack of suitable attachment techniques. We describe a novel waistband for attaching external radiotransmitters to anurans and evaluate the percentages of resulting abrasions, lacerations, and shed transmitters. We used radiotelemetry to monitor movements and habitat use of wood frogs (Lithobates sylvaticus) in 2006 and 2011–2013 in Maine, USA; American toads (Anaxyrus americanus) in 2012 in North Carolina, USA; and, wood frogs, southern leopard frogs (L. sphenocephalus), and green frogs (L. clamitans) in 2012 …


University Of Maine Proposal For Joining The Nsf Center For Advanced Forestry Systems, Robert G. Wagner, Aaron R. Weiskittel Apr 2015

University Of Maine Proposal For Joining The Nsf Center For Advanced Forestry Systems, Robert G. Wagner, Aaron R. Weiskittel

University of Maine Office of Research Administration: Grant Reports

University of Maine (UM) is planning to join the existing multi-university Industry/University Cooperative Research Center (I/UCRC) entitled "The Center for Advanced Forestry Systems" (CAFS) which was established in 2007 with four member institutions: North Carolina State University (lead university), Oregon State University, Purdue University and Virginia Tech. The primary focus of the proposed research site within CAFS will be modeling the productivity of managed natural forests. This research focus will be addressed at multiple scales ranging from the individual tree to the regional forest. UM has a long history of applied research in the management of naturally regenerated forests as …

Extent And Severity Of Caliciopsis Canker In New England, Usa: An Emerging Disease Of Eastern White Pine (Pinus Strobus L.), Isabel A. Munck, William Livingston, Kyle Lombaerd, Thomas Luther, William D. Ostrofsky, Stephen Wyka, Kirk Broders, Jennifer Weimer Jan 2015

Extent And Severity Of Caliciopsis Canker In New England, Usa: An Emerging Disease Of Eastern White Pine (Pinus Strobus L.), Isabel A. Munck, William Livingston, Kyle Lombaerd, Thomas Luther, William D. Ostrofsky, Stephen Wyka, Kirk Broders, Jennifer Weimer

Forest Resources Faculty Scholarship

Caliciopsis canker is an emerging problem in Pinus growing regions of Eastern North America. The fungal disease caused by Caliciopsis pinea is associated with overstocked stands and poor sites, but few quantitative data are available. The objective of this study, therefore, was to assess the extent and severity of Caliciopsis canker and to explore environmental variables associated with disease to identify areas at risk of damage. During 2014, 58 sites across New England with >75% P. strobus basal area in public lands were surveyed. Most sites (72%) had Caliciopsis canker signs or symptoms. Caliciopsis pinea was successfully identified with molecular …
