Assessing above- and belowground competitive effects in pure and mixed stands of jack pine (Pinus banksiana) and black spruce (Picea mariana)
(2009)Ecological principles of niche, competition and competitive reduction suggest that competition in mixed stands composed of pine and spruce may experience positive interactions through (1) vertical stratification of canopy ... -
Ecologically-based taper equations for major tree species in Manitoba
(2004)Kozak's variable exponent taper equation was fitted for balsam poplar (Populus balsamifera L.), trembling aspen (Populus tremuloides Michx.), white spruce (Picea glauca (Moench) Voss), black spruce (Picea mariana (Mill.) ... -
Effective root growth potential of jack pine (Pinus banksiana Lamb.) container stock / by Alan M. Wiensczyk
(1989)The effective root growth potential (RGP) of both potted and outplanted jack pine seedlings grown in Lannen-Sokeri FH-408 paperpots and Can-Am #2 Multipots was measured on three test dates during the summers of 1986 and ... -
Effects of Photoperiod, Soil Moisture and Soil Temperature on the Northward Migration Potential of Jack Pine under the Scenario of Doubled Atmospheric CO2 Concentration
(2016)Climate envelope models predict that boreal trees can potentially migrate northward by as much as 10º by 2100 as a consequence of the predicted climate change associated with the doubling of atmospheric CO2 concentration, ... -
Effects of soil temperature on a coupled photosynthesis-stomatal conductance model for four boreal tree species
(2000)In order to examine the effects of soil temperature on a coupled photosynthesis-stomatal conductance model, seedlings of trembling aspen (Populus tremuloides Michx), jack pine (Pinsu banksiana Lamb. ), black spruce (Picea ... -
An Examination of bark beetles and their associated blue stain fungi on boreal jack pine (Pinus banksiana) and white spruce (Picea glauca) in the Thunder Bay Region
(2009)Blue stain, caused by members of the Ophiostomatales, is of concern to the forest industry because it can quickly devalue timber by penetrating deep into the sapwood and creating dark blue to black staining. These fungi ... -
Genecology of jack pine in north central Ontario
(1995)To understand the pattern of adaptive variation of jack pine in north central Ontario better, short-term provenance tests were established. Seed was collected from 64 sites to the east and west of Lake Nipigon and grown ... -
Ground speed : its influence on the direct seeding of jack pine (Pinus banksiana Lamb.) with the Bracke scarifier
(1993)The effects that ground speed and obstacle height have upon microsite creation by the Bracke scarifier and upon the seeding characteristics of the integral seeder were studied. The study was conducted in a former gravel ... -
Pollen pool heterogeneity in jack pine (Pinus banksiana Lamb.) : a problem for estimating population outcrossing rate? / Yong-Bi Fu
(1990)Pollen pool heterogeneity, which violates an assumption of the mixed-mating model, is one of the major problems facing population geneticists concerned with measuring plant mating systems. In the present study, isozyme ... -
The influence of acid rain and drought on early growth and development of jack pine and balsam poplar
(1994)The influence of "acid rain" (watering with tap water acidified to pH 3.0 ) and drought on jack pine seedlings and balsam poplar cuttings growing in two different soil types was studied in a short-term greenhouse experiment. ...
