Multivariate analysis for assessment of the tree populations based on dendrometric data with an example of similarity among Norway spruce subpopulations
dendrometry hierarchical classification ordination Picea abies
2018/3/6
The new method for evaluation of tree populations presented here is based on a correlation analysis within a set of
dendrometric variables. The correlation analysis is carried out for each population...
Prevalence of Tree Regeneration by Sprouting and Seeding Along a Rainfall Gradient in Hawai’i
feral pig disturbance Sus scrofa tropical dry forest tropical wet forest
2015/11/13
Drought stress in tropical dry forests is thought to result in greater asexual regeneration via vegetative sprouting (e.g., basal, root, and branch layering) than occurs in
moister tropical forests. ...
HYBRIDIZATION AMONG DOMINANT TREE SPECIES CORRELATES POSITIVELY WITH UNDERSTORY PLANT DIVERSITY
canopy – understory interactions community genetics
2015/11/13
Premise of the study : Elucidating the factors that determine the abundance and distribution of species remains a central goal of
ecology. It is well recognized that genetic differences among indivi...
Generalized additive models as an alternative approach to the modelling of the tree height-diameter relationship
nonparametric method Norway spruce Petterson function
2015/7/2
Generalized additive models were tested using three types of smoothing functions as an alternative for
modelling the height curve. The models were produced for 23 forest stands of Norway spruce (Pic...
Aboveground biomass and nutrients in an 18-years-old stand of blue spruce (Picea pungens Engelm.) as a substitute tree species
aboveground biomass nutrients blue spruce substitute tree species stands
2015/4/14
Sample trees were taken for analyses from an 18-years-old blue spruce stand growing in the summit part of the Jizerské hory Mts. (Czech Republic). The sample trees were measured and dry matter and nut...
Can 13C stable isotope record of Norway spruce tree rings display the effect of environmental conditions?
Δ13C air pollution tree physiology Bohemian Forest Mts. soil pH aluminium soil acidification
2015/3/12
The Bohemian Forest Mts. (Šumava) were exposed to heavy atmospheric pollution in the last century. A possible negative effect of atmospheric pollution on tree physiology has been studied using th...
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...
DIFFERENTIAL RESPONSES TO GUANO FERTILIZATION AMONG TROPICAL TREE SPECIES WITH VARYING FUNCTIONAL TRAITS
functional traits guano inputs seabirds tropical forests
2015/11/13
Premise of the study : Seabirds often cause signifi cant changes to soil properties, and seabird-dominated systems often host
unique plant communities. This study experimentally (1) examined s...
Studies of Tree Architecture:Linking Tree Physiology and Forest Community Dynamics
canopy structure life-history strategy module morphological plasticity succession
2009/8/28
Tree architecture represents various ecological and physiological functions, such as acquisition of light, spatial distribution of vegetative and reproductive organs and pathway for water and nutrient...
