Brown Bear (Ursus arctos) Predation of Broad Whitefish (Coregonus nasus) in the Mackenzie Delta Region, Northwest Territories
Download2009
On 2 October 2007, we observed evidence of at least one brown bear (Ursus arctos) predating and caching broad whitefish (Coregonus nasus) at Pete’s Creek, a tributary of the Mackenzie River, Northwest Territories. While predation on whitefish by brown bears has been reported as traditional...

Fall 2015
The boreal ecotype of woodland caribou (Rangifer tarandus caribou) is federally listed as Threatened due to population declines throughout its distribution. High mortality rates of neonate calves (≤ 4 weeks old) due to predation are a key demographic factor contributing to population declines...

Characterizing adaptive morphological features and resource selection of Rocky Mountain Sculpin (Cottus sp.), a species at risk in Canada
DownloadFall 2017
Freshwater biodiversity is presently one of the world’s largest conservation concerns. Both direct and indirect human activities contributing to waterway modifications, climate change, and habitat alteration are causing major declines in freshwater fish species richness and abundance. While these...

Mariana B. Nagy-Reis, Mark A. Lewis, William F. Jensen, Mark S. Boyce
Understanding the underlying mechanisms driving population demographics such as species-habitat relationships and the spatial scale in which these relationships occur is essential for developing optimal management strategies. Here we evaluated how landscape characteristics and winter severity...

Diagenetic Controls on Hydrothermal Fluid Flow in the Osiris, Isis, and Isis East Carlin-Type Gold Showings, Nadaleen Trend, Yukon
DownloadFall 2015
Following ATAC Resources Ltd.’s 2010 discovery of the gold prospects in the Nadaleen Trend (Central Yukon), company geologists and consultants determined that Precambrian carbonate rocks within the trend contain large endowments of gold located in the hinges of anticlines and fault zones. ...

Disentangling the relative effects of structural complexity and substrate composition on fish habitat selection in coral reef environments
DownloadFall 2021
Identifying features of biogenic habitats (i.e. made of living plants and animals) that attract and retain resident species is a key theme in ecology with important implications for habitat conservation and restoration. Using corals (class Anthozoa, phylum Cnidaria) —a group of foundational...

Effects of hunting on the demographics, movement, and habitat selection of American black bears (Ursus americanus)
Download2008
I conducted a large-scale experiment to determine the effects of hunting on the demographics and behaviour of American black bears (Ursus americanus ). I monitored 290 bears, a subset of which were equipped with VHF and GPS radio-collars, in 2 hunted areas and an adjoining unhunted area in the...

Environmental Controls on Alternating Aragonite-calcite Laminations in Notch-speleothems from Cayman Brac, Cayman Islands, British West Indies
DownloadFall 2017
Speleothems that grow in semi-exposed surface environments, such as wave-cut notches, are not well understood despite their widespread distribution. The +6.4 m-high wave-cut notch on Cayman Brac, that formed ~ 125 ka ago, is decorated with stalactites, stalagmites, and columns that grew between...

Factors affecting larval growth and development of the boreal chorus frog Pseudacris maculata
DownloadFall 2010
The boreal chorus frog (Pseudacris maculata) is a widespread species but we know little of its ecology. I examined the nature and existence of competitive mechanisms operating between larvae of the boreal chorus frog and wood frog (Lithobates sylvaticus) from field, mesocosm and laboratory venues...
