Effects of species mixtures on fine root production in a young boreal forest
(2019)
1. Fine roots (< 2 mm) play a key role in terrestrial ecosystem processes. Species diversity
loss has been recognized as one of the primary global change drivers that can have
profound negative effects on ecosystem ...
The dynamic effects of tree species diversity on nitrogen in soil
(2019)
The availability of nitrogen in soil is one of the most important factors for tree
growth. Although tree species mixtures are known to increase forest productivity, it
remains unclear how they affect soil nitrogen. In ...
A script for the automatic delineation of canopy gaps from raster images and incorporation of analysis with Ontario’s FRI datasets
(2019)
This thesis project serves as a tool for resource managers looking to delineate gaps in the forest canopy, where a Canopy Height Model raster is available. Once identified, analysis is performed in order to assess the ...
Impacts of different harvesting methods on forest environment
(2019)
Harvesting methods are an important component of forestry management. Determining the impact of harvesting methods on forest environment can help us to do it more efficiently. In this paper, the methods, impact and intensive ...
Mycoparasites and decay fungi: a study of their ecological interactions on wood blocks of Betula papyrifera
(2020)
Decay fungi are an extremely important part of the forest ecosystem and provide essential ecosystem services including the breakdown of complex organic compounds and nutrient release. However, this important group of fungi ...
A review of the biological significance of coarse woody debris in forest ecosystems and its positive impact on forest characteristics
(2020)
Coarse Woody Debris (CWD) is considered any woody decay that has fallen on the forest floor. This important piece of forest ecology has a large influence on a variety of forest characteristics. This thesis first evaluates ...
Factors affecting the structure and function of forest ecosystem: disturbance and climate change
(2021)
This paper discusses the effects of climate change and disturbance on forest ecosystems.
At present, the increasing temperature caused by global warming and the occurrence of various
fire events has posed a huge challenge ...
Windthrow and forest regeneration, structure, and composition in boreal forests
(2020)
Windthrow is a self-identified disturbance factor in forests, which has a huge
ecological and economic impact.
This paper discusses the influence of windthrow on boreal forests and analyzes the
changes of tree ecosystems ...
Analysis on the influencing factors of forest natural regeneration in northern China
(2021)
The purpose of this paper is to clarify that the differences in natural regeneration
between the two forests in northern China are caused by precipitation, altitude, temperature, and canopy density. Similarly, the ...
Effects of the nitrogen deposition on the forest ecosystems: an overview
(2023)
Human activities exacerbate the production and emission of reactive nitrogen and lead to
the increase and globalization of nitrogen deposition. At present, the interference of
human activities in the global nitrogen cycle ...
