Ungulate predation and ecological roles of wolves and coyotes in eastern North America
Understanding the ecological roles of species that influence ecosystem processes is a central goal of ecology and conservation biology. Eastern coyotes have ascended to the role of apex predator across much of eastern North America since the extirpation of wolves and there has been considerable confusion regarding their ability to prey on ungulates and their ecological niche relative to wolves. This study investigated intrinsic and extrinsic influences on per capita kill rates of white-tailed deer and moose during winter by sympatric packs of eastern coyotes, eastern wolves, and admixed canids in Ontario, Canada to clarify the predatory ability and ecological roles of the different canid top predators of eastern North America.
Capacity shortfalls hinder the performance of marine protected areas globally
Marine protected areas (MPAs) are increasingly being used globally as a tool to conserve marine resources. However, the extent to which MPAS areeffectively managed and how management influences conservation outcomes have not been investigated. This study composed a global database of management and fish population data to asses: MPA management processes; the effects of MPAs on fish populations; and relationships between management processes and ecological effects.
BIG ANIMALS and SMALL PARKS - Implications of Wildlife Distribution and Movements for Expansion of Nahanni National Park Reserve
This WCS report describes the ‘boundary problem’ of Nahanni National Park Reserve in the Northwest Territories of Canada where it’s small size and narrow shape presents a challenge for protection of wide ranging species. Surveys were conducted on the distribution and seasonal movements of grizzly bears, Dall’s sheep, and woodland caribou to inform decisions on park expansion and land use planning.
Carnivores and Corridors in the Crowsnest Pass
This Alberta Species at Risk Report examines the habitat use and movements of grizzly bears and cougars in the Crowsnest Pass of southern Albert, a region with high habitat fragmentation due to human land uses.
Caribou and the North - A Shared Future
The book explores the reason for the interlinked fate of caribou and the North, as it relates to migratory tundra caribou, boreal forest caribou, and mountain caribou in Canada and the U.S. Climate change coupled with widespread oil, gas, and mineral development adds new pressure for the region’s iconic wildlife.
Dead or alive - animal sampling during Ebola hemorrhagic fever outbreaks in humans
This article provides guidelines for identifying animal sources of disease outbreaks, specifically sources of Ebolavirus (EBOV) during outbreaks of human Ebola hemorrhagic fever (EHF). Guidance is given on sampling animals when resources are limited, when targeting specific species, and when rapid diagnosis of EBOV in animal reservoirs is necessary.
Lynx Survey in the Adirondack Park
This article describes a survey to determine whether there is a population of Canada lynx within the area around the High Peaks region of the Adirondacks. The survey involved a non-invasive technique using the natural cheek-rubbing behavior of cats for hair collection and DNA analysis. This was a follow-up survey to the release of 83 translocated lynx by a team of biologists from SUNY ESF in the late 1980's.
Natural Solutions - Protected areas helping people cope with climate change
This book articulates how protected areas contribute significantly to reducing impacts of climate change and what is needed for protected area management to be even more effective. The message of this book is to convey the importance of the impacts of climate change on biodiversity to policy makers to encourage effective policies and funding mechanisms.
Noninvasive Survey Methods for Carnivores
This book is a comprehensive guide for wildlife researchers who seek to conduct carnivore surveys using the most up-to-date scientific approaches. Twenty-five experts from across North America discuss strategies for implementing surveys across a broad range of habitats, providing input on survey design, sample collection, DNA and endocrine analyses, and data analysis.
Projecting transition probabilities for regular public roads at the ecoregional scale - A Northern Appalachian, Acadian case study
This article investigates the growth of public roads in Maine over a 17-year period to select the best model to predict future road growth. The selected model predicted 0.5 million km of new roads in the Northern Appalachian / Acadian ecoregion for the next two decades. This type of model will assist planning agencies and conservation organizations to protect against biodiversity threats due to road expansion.
