Acoustic properties of four central boreal tree species for potential use in instruments
(2023)
In resonance wood, acoustic velocity, density profiles, and ring characteristics
play an important role. Multiple factors cause variation of these properties, like the
difference between juvenile wood and mature wood, ...
Increasing fruit production in wild populations of pawpaw (Asimina Triloba (L) Dunal) trees in southern Ontario
(2023)
The pawpaw (Asimina triloba (L) Dunal) is a unique native understory tree
species found in the Deciduous and Carolinian forest regions in Southern
Ontario. It is at the edge of its range in Ontario, most of the population ...
Investigation of adaptive variation of black spruce in 29-year height growth of Black Spruce in a northwestern Ontario provenance trial
(2023)
Seed sources from across northwestern Ontario were used to establish a black spruce
provenance trial at the former Thunder Bay Forest Nursery located on 25th Sideroad,
Thunder Bay. The heights of these trees were measured ...
Stigma resistance versus self-stigma in university students with mental health problems
(2023)
Self-stigma is the process by which an individual is aware of, agrees with, and internalizes

aware of societal stigma, yet ...
Assessing the vulnerability of south-central Ontario’s maple syrup industry to climate change: a multidisciplinary approach
(2023)
Productivity of Ontario’s maple syrup industry is tied to a specific climate window. As
climate continues to change, there is growing concern over the industry’s vulnerability given its
reliance on stable climate conditions ...
A framework to avoid maloperation of transformer differential protection under geomagnetic disturbances
(2023)
Geomagnetically Induced Currents (GICs), which are generated due to Geomagnetic
Disturbances (GMDs), can saturate the cores of power transformers and their associated
Current Transformers (CTs). To avoid maloperation of ...
Modulation scheme investigation for high-power medium-voltage current source converter based drives
(2023)
Pulse width modulated (PWM) current source converter (CSC) based drives are commonly used in high-power (1-10 MW), medium-voltage (MV) (2.3-6.6 kV) applications.
These drives feature a simple converter structure, inherent ...
Natural regeneration in Norway spruce and red pine plantations in Dufferin County Ontario - a case study
(2023)
Norway spruce has been demonstrated to be a highly productive species in
eastern temperate regions of Canada and is commonly utilized for the afforestation of
poor soils. However, literature on the understory regeneration ...
Effect of tree species diversity on species growth rate in the Saskatchewan boreal forest
(2023)
Diverse ecosystems are crucial to combating climate change. This study aims to examine
the impacts of tree species diversity on growth rate of seven boreal tree species. Data from
permanent sample plots located in the ...
The effects of mechanical site preparation, unscarified and refill land types on the growth and establishment of planted seedlings
(2023)
This study examines the effects of different site types
of tree planting blocks on the growth and establishment of
planted seedlings within the Black Spruce Forest, north of
Thunder Bay, Ontario. Measurements of planted ...
