Non-genetic data supporting genetic evidence for the eastern wolf
L. David Mech
2011, Northeastern Naturalist (18) 521-526
Two schools of thought dominate the molecular-genetics literature on Canis spp. (wolves) in the western Great Lakes region of the US and Canada: (1) they are hybrids between Canis lupus (Gray Wolf) and Canis latrans (Coyote), or (2) they are hybrids between the Gray Wolf and Canis lycaon (Eastern Wolf)....

The role of demographic compensation theory in incidental take assessments for endangered species
Conor P. McGowan, Mark R. Ryan, Michael C. Runge, Joshua J. Millspaugh, Jean Fitts Cochrane
2011, Biological Conservation (144) 730-737
Many endangered species laws provide exceptions to legislated prohibitions through incidental take provisions as long as take is the result of unintended consequences of an otherwise legal activity. These allowances presumably invoke the theory of demographic compensation, commonly applied to harvested species, by allowing limited harm as long as the...
The relation of harvesting intensity to changes in soil, soil water, and stream chemistry in a northern hardwood forest, Catskill Mountains, USA
Jason Siemion, Douglas A. Burns, Peter S. Murdoch, Rene H. Germain
2011, Forest Ecology and Management (261) 1510-1519
Previous studies have shown that clearcutting of northern hardwood forests mobilizes base cations, inorganic monomeric aluminum (Alim), and nitrate (NO3--N) from soils to surface waters, but the effects of partial harvests on NO3--N have been less frequently studied. In this study we describe the effects of a series of partial...

Here, we conduct a literature review and a small meta-analysis of wave attenuation data, and we find...
Nest survival of American Coots relative to grazing, burning, and water depths
Jane E. Austin, Deborah A. Buhl
2011, Avian Conservation and Ecology (6) 1-14
Water and emergent vegetation are key features influencing nest site selection and success for many marsh-nesting waterbirds. Wetland management practices such as grazing, burning, and water-level manipulations directly affect these features and can influence nest survival. We used model selection and before-after-control-impact approaches to evaluate the effects of water depth...
