Variation in Carbon Content among the Major Tree Species in Hemiboreal Forests in Latvia
living biomass greenhouse gas inventory Norway spruce Scots pine birch European aspen
2023/12/15
This study was designed to estimate the variation in non-volatile carbon (C) content in different above- and belowground tree parts (stem, living branches, dead branches, stumps, coarse roots and smal...
Understory Plant Abundance Is More Important than Species Richness in Explaining Soil Nutrient Variation Following Afforestation on the Eastern Loess Plateau, China
afforestation soil organic carbon total nitrogen total phosphorus understory vegetation biomass
2023/12/1
Afforestation plays an important role in controlling soil erosion and nutrient loss on the Loess Plateau in China. However, previous studies on soil nutrient changes have mainly focused on the effects...
Topography Affects Tree Species Distribution and Biomass Variation in a Warm Temperate, Secondary Forest
biomass variation forest dynamics plot habitat classification topography torus translation
2024/2/28
A thorough understanding of carbon storage patterns in forest ecosystems is crucial for forest management to slow the rate of climate change. Here, we explored fine-scale biomass spatial patterns in a...
Investigating the variation of diameter and height of Populus sp. clone I-214 under various fertilization treatments in northern Greece – a case study
biomass production Entisols fertilizers general linear model multivariate procedure young poplar trees
2017/4/6
The study of young poplar tree characteristics like initial diameter and height as well as mineral fertilization that promotes the rapid growth of trees for biomass production was the aim of this rese...
Variation of wood density in Turkish hazel (Corylus colurna L.) grown in the Czech Republic
Corylus colurna L wood density variability
2015/4/14
The aim of this study was to investigate the wood density of Turkish hazel (Corylus colurna L.), an introduced species in the Czech Republic. Sample trees coming from a Czech site were tested for basi...
Variation of conducting area in stems of European larch (Larix deciduas) growing in fresh mixed coniferous forest and fresh mixed forest sites
conducting area European larch mean ring conducting area relative conducting area social class of tree position
2015/3/20
The paper presents an attempt to determine conducting area (CA), relative conducting area (CA.k–1) and mean ring conducting area (CAar) on discs cut at breast height from stems of larch trees growing ...
Disturbances in variation of the annual ring width of Norway spruce in the Polish Western Beskids Mountains
tree-ring ring width variation Norway spruce Polish Beskids Mountains
2015/2/6
Changes in radial increment of Norway spruce in 25 stands more than 100 years old were analysed. Stands were growing on sites of different exposure situated at 450–1,200 m above sea level in the Polis...
Variation of the tree ring micro-hardness demonstrated on spruce wood
wood tree ring micro-hardness penetration strength
2015/2/2
Micro-hardness was used for the study of wood structure (Norway spruce) in the line perpendicular to tree rings (radial surface). The steel indentor 0.25 mm in diameter with flat head was used for thi...
Growth Characteristics, Biomass and Chlorophyll Fluorescence Variation of Garhwal Himalaya’s Fodder and Fuel Wood Tree Species at the Nursery Stage
Scarcity Fodder and Fuel Wood Species Screening Growth Biomass Chlorophyll
2013/3/4
Fodder and fuel wood deficiency in the Himalayan region is well recognized. Rural inhabitants are exploiting these forest resources for their livelihood for generations which leads to severe deforesta...
Forest Tree Species Diversity Depends on Individual Variation（图）
Forest Tree Species Diversity Individual Variation
2010/3/4
Models clearly show that the coexistence of competing species depends on those species responding differently to the availability of resources. Then why do studies comparing competing tree species dra...
