The honey bee Apis mellifera is a model organism for studying learning and memory in insects. Although much work has been done to study olfactory learning using the proboscis extension reflex paradigm, we currently lack a high throughput method to st

Imperfect detection leads to underestimates of species presence and decreases the reliability of survey data. Imperfect detection has not been examined in detail for boreal forest understory plants, despite widespread use of surveys for rare plants p

Riparian ecotones at lakeshore edges are prominent features on the hetero- geneous boreal forest landscape. We introduce a new method (the critical values approach), which incorporates inherent variability in interior forest, to quantify distance of

We examined the impacts of harvesting and mechanical site preparation (MSP) on soil chemical properties of mixed-wood boreal forest sites in west central Alberta. Treatments included: 1) disc trencher, hinge, and trench microsites; 2) ripper plow, hi

In their recently published discussion paper, Lieffers and Stadt (2003) comment on an article in which we documented aging errors in understory white spruce (Picea glauca (Moench) Voss) in the boreal mixedwood (Peters et al. 2002). We believe that th

Rates of net assimilation and related ecophysiological parameters were measured three times during the 1988 growing season on a total of 80 black spruce (Piceamariana (Mill.) B.S.P.) and 80 tamarack (Larixlaricina (Du Roi) K. Koch) trees from two pea
