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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
The response of avian predator populations to forest tent caterpillar (Malacosoma disstria; Lepidoptera: Lasiocampidae) outbreaks in Ontario, Canada
(2020)Outbreaks of insect defoliators have broad ecological effects on forested ecosystems because they can cause extensive mortality in host tree populations. They also represent peaks in the density of food for specialist ... -
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 ... -
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 ... -
Spatiotemporal effects of climate on the relationship between tree diversity and forest ecosystem functioning
(2020)Worldwide, forest ecosystem functioning and plant diversity have been altered by global environmental change. Understanding the relationship between biodiversity and ecosystem functioning with long-term environmental ... -
Trade-offs between economic gains and ecological functions following forest management alternatives in boreal forests
(2018)Intensive forest management activities that maximize economic gains could negatively impact the long-term sustainability of ecological functions and associated ecosystem services. Understanding the trade-offs between ... -
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 ...
