Diapause and overwintering of two spruce bark beetle species

Publications Posted on: July 19, 2017
Diapause, a strategy to endure unfavourable conditions (e.g. cold winters) is commonly found in ectothermic organisms and is characterized by an arrest of development and reproduction, a reduction ofmetabolic rate, and an increased resistance to adversity. Diapause, in addition to adaptations for surviving low winter temperatures, significantly influences phenology, voltinism and ultimately population growth.

Environmental effects on germination of Carex utriculata and Carex nebrascensis relative to riparian restoration

Publications Posted on: June 06, 2012
Seasonal riparian seedbed temperatures were measured and germination of Carex utriculata and C. nebrascensis seeds was tested in relation to chilling, perigynia removal, incubation temperature, and light to help guide propagation and direct seeding of these species for riparian restoration.
