Lake trout and their egg predators' ability to locate spawning substrate using olfaction
(2014-01-22)Lake trout spawning sites, and the substrate on these sites, are structurally unique in many ways. These sites are generally at the end of the fetch of a lake, close to shore (1 m) and composed of small to medium sized ... -
Landscape genetic analysis of population structure and barriers to gene flow in boreal woodland caribou (Rangifer tarandus caribou)
(2023)This study examines patterns of population genetic structure and gene flow of boreal woodland caribou (Rangifer tarandus caribou), which are experiencing declining population sizes across North America. Compared to ... -
Landscape indicators of Old Tower Road archaeological site (DbJm-6), Thunder Bay District
(2015-10-21)This thesis addresses two research objectives. The first investigates landscape factors in the paleo-environment which may have influenced the geographic positioning of an archaeological site near Thunder Bay. The time ... -
Late Holocene paleovegetation and fire history of Northern Lake of the Woods and the Woodland Period
(2023)This thesis analyzes two Late Holocene lake sediment cores which were collected from the vicinity of two archaeological sites in northeastern Lake of the Woods, Ontario: the Bundoran Site (DjKn-5) and the Bud Site (DjKn-6). ... -
Late Paleoindian biface manufacture: a case study from the Mackenzie I site (DdJf-9) near Thunder Bay, Ontario
(2015-06-15)The Mackenzie Sites appear to form part of the Late Paleoindian Lakehead Complex that occupied the unglaciated peninsula between Glacial Lakes Agassiz and Minong during the terminal Pleistocene. A number of sites and ... -
