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 ... -
Carbon dynamics of boreal mixedwoods in central Canada
(2009)Large amount of carbon (C) stored in boreal forest ecosystems plays an important role in the global carbon cycle. Forest ecosystem C is stored in four major pools: live vegetation (above-and below ground), dead woody ... -
Carbon storage dynamics and tree growth response to species diversity in boreal forests
(2018)The boreal forest plays a critical role in regulating the global carbon (C) cycle. Both wildfire and harvesting affect ecosystem C. However, the long-term recovery of forest C storage with a diverse range of overstory ... -
Climate change-associated temporal increase of tree mortality and its consequences in central and western Canadian boreal forests
(2014-01-22)Tree mortality influences forest structure, composition and ecosystem functions. To assess how recent climate changes affected tree mortality, observational studies conducted in old-growth forests have shown that tree ... -
Concepts, theories and models of succession in the boreal forest of Central Canada
(2009)Predicting plant community compositional responses to changing environmental conditions and disturbances is a key element of forecasting and managing for the effects of global climate change. With advances in ecological ... -
Drought effects on soil enzyme activity
(2021)Soil extracellular enzyme activity (EEA) is a strong predictor for soil health. EEA cycle nutrients within terrestrial systems, processing carbon, nitrogen, and phosphorous, while also mineralizing and stabilizing gas. ... -
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 ... -
Effect of harvest intensity on soil carbon and nutrients across global forests: a meta-analysis
(2018)Logging residues can retain important nutrients for tree growth after biomass harvesting. However, increasing the harvest intensity may decrease soil nutrient stores stocks and affect biomass productivity. Using 2207 ... -
Effects of species composition and season change on fine root length increase with stand development in Northwest Ontario
(2018)The root length is an important indicator to reflect the growth characteristics of the tree, but the root length is difficult to obtain through direct measurement, and the root as a sensitive organ of plants can indirectly ... -
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 ... -
The Fine root dynamics after stand-replacing fire and clearcutting in the boreal forest of central Canada
(2012-11-10)In boreal forest ecosystems, stand age is a key driver of forest ecosystem productivity, carbon storage/sequestration, and other ecosystem functions. The age-related decline of aboveground productivity is well known in ... -
Foliar nutrient resorption and litterfall production with stand age, overstory composition, and disturbance origin in boreal forests
(2015-01-13)Nutrient resorption (NuR) prior to developmental senescence allows for nutrient conservation in plants, driven primarily by genetics, development stage, climate and soil fertility, and litterfall is the vector for the ... -
Global environmental change effects on forest dynamics: lessons from permanent sample plot networks
(2019)Global environmental change caused by anthropogenic emissions of greenhouse gasses is a major threat to forest ecosystems globally. Before we can begin to adequately mitigate these threats, we first must understand how ... -
Holocene fire-climate-vegetation dynamics in Central Canadian Shield boreal forests of Northwestern Ontario, Canada / by Dominic Lafontaine-Senici.
(2014)The boreal forest is the largest terrestrial ecosystem in North America, one of the least disturbed by humans, and most disturbed by fire. This combination makes it an ideal system to explore the environmental controls on ... -
Influence of fire, logging, and overstory composition on understory abundance, diversity, and composition in boreal forests, Ontario Canada
(2006)Study area : Northwestern Ontario -
Influence of overstory composition on understory vegetation and resource environment in the boreal forests of Canada
(2010)Study areas : Thunder Bay Region, Northwestern Ontario ; Northeastern Quebec. -
Influence of riparian harvesting on boreal understory vegetation
(2014-01-22)In the boreal forest, understory vegetation accounts for the majority of floristic diversity and affects overstory succession and productivity, nutrient cycling, and wildlife habitat. In riparian forests, understory ... -
Linking environment, biodiversity, and ecosystem functions in forest ecosystems
(2014-12-16)The positive biodiversity and ecosystem functions relationship (BEF) has been well established, especially in controlled experiments. However, a coherent study to examine the multiple relationships in BEF in natural ... -
Nesting dynamics of the scarlet ibis (Eudocimus ruber) in Trinidad, West Indies
(2009)The effect of human disturbance on colonial waterbirds is a global issue. Many colonial waterbirds are migratory, and their protection depends on balancing conservation of their habitats and habits across many regions. ...
