Christopher J. Hein, Duncan M. FitzGerald, Emily A. Carruthers, Byron D. Stone, Allen M. Gontz
2011, Conference Paper, The Proceedings of the Coastal Sediments 2011
Barrier islands develop through a variety of processes, including spit accretion, barrier elongation, and inlet filling. New geophysical and sedimentological data provide a means of documenting the presence of a paleoinlet within a barrier lithosome in the western Gulf of Maine, illuminating the process of backbarrier infilling and its effect...
Novel primers for complete mitochondrial cytochrome b genesequencing in mammals
Ashwin Naidu, Robert R. Fitak, Adrian Munguia-Vega, Melanie Culver
2011, Molecular Ecology Resources (12) 191-196
Sequence-based species identification relies on the extent and integrity of sequence data available in online databases such as GenBank. When identifying species from a sample of unknown origin, partial DNA sequences obtained from the sample are aligned against existing sequences in databases. When the sequence from the matching species is...

Development of a pan-Arctic monitoring plan for polar bears: Background paper
Dag Vongraven, Elizabeth L. Peacock
2011, Report
Polar bears (Ursus maritimus), by their very nature, and the extreme, remote environment in which they live, are inherently difficult to study and monitor. Monitoring polar bear populations is both arduous and costly and, to be effective, must be a long-term commitment. There are few jurisdictional governments and management...
