The Conservation and Management of Wolverine (Gulo gulo) Populations in Northern Idaho to Help Prevent Human Caused Extirpation from the Contiguous United States
Thu, 05/02/2013 - 11:21
Abstract: Wolverines (Gulo gulo) were once a thriving species in the North Western United States, but large scale trapping and poison programs in the early 1900s lead to the species near extinction. Since then, populations in the United States have been struggling to maintain a strong presence in Idaho. Its current listing as threatened on the Endangered Species Act prohibits hunting and trapping, but more management is needed to sustain populations. Human development and recreation activities have caused wolverines to disperse from its nature range. Using habitat preservation techniques on current and historical wolverine habitat, increase availability and connectivity will improve dispersal. Close relationship with state officials will provide protection regarding land use, recreation, hunting, trapping and harassment. Public education will teach residents ways they can help prevent wolverine populations from further decline. Extensive research and population monitoring are needed due to the currently declining populations and the low fecundity of the species.

Monitoring the Zebra Mussel Invasion Front: Use of New Technology
Thu, 02/09/2012 - 15:39
Abstract: Zebra mussels are invasive mollusks that are affecting the well-being of the water bodies in the United States. This study uses environmental DNA (eDNA) is a sensitive early detection system that may be useful in monitoring their spread. The purpose of this study is to determine the effectiveness of eDNA technology in identifying infested water bodies, to determine if zebra mussel DNA is in the Adirondack water bodies not known to be infested, if the water chemistry of these water bodies is favorable for zebra mussel establishment, and if the eDNA technology is transferable to an institution like Paul Smith’s College. Eighteen lakes, all in New York State were sampled, fifteen of which are located in the Adirondack Park. DNA was extracted from water and plankton samples and species specific primers were used for PCR amplification to determine if zebra mussel DNA was present. Of seven samples taken from sites known to be infested, five of these tested positive for zebra mussel eDNA. Four lakes not known to be infested within the Park also tested positive for zebra mussel eDNA. Based on zebra mussel risk parameters (water chemistry) applied to 1,469 Adirondack water bodies, less than 3% are at risk of zebra mussel establishment. However it is possible that established populations could occur at microsites that may have locally high levels of calcium and higher pH.
