Lake expansion and wetland flooding on the Great Slave Lake Plain
chercheur principal: Armstrong, Terry
Année(s) de permis: 2014 2013 2012 2011 2010
Résumé: The primary objective is to examine changes in lake area in the ecoregion, investigate whether recent changes are part of a longer-term cycle related to large-scale weather patterns or due to permanent changes to the climate and hydrology of the region. Data collection in the field will consist of taking core samples from trees in the area. This technique involves using a hollow drill to cut i...

The role of predation in nesting success of black brant and lesser snow geese
chercheur principal: Armstrong, Terry
Année(s) de permis: 1993 1992 1991
Résumé: This ongoing study will involve observing glaucous gulls as they prey on nests of black brant and lesser snow geese. I will attempt to determine why the gulls seem to be more successful when attacking the nests of brant than those of snow geese. I will examine the feeding behaviour of the gulls and the defense behaviour of the geese. I will also examine the nesting success and clutch sizes of b...
