Concepts
18 concepts
fire regime
Pattern of fire occurrence including frequency, intensity, and timing that shapes ecosystem dynamics
montane ecosystem
Mountain ecosystem characterized by specific elevation, climate, and vegetation adapted to montane conditions
root turnover
stand structure
The horizontal and vertical distribution of components of a forest stand including the height, diameter, crown layers, and stems of trees, shrubs, herbaceous understory, snags, and down woody debris
vapor pressure deficit
The difference between the amount of moisture in the air and how much moisture the air can hold when it is saturated, indicating evaporative demand
allometric relationships
Mathematical relationships that describe how tree dimensions and biomass scale with each other
individual tree detection
Automated algorithms for identifying and delineating individual trees from LiDAR point cloud data
spectral sensitivity
stable isotope mixing model
Analytical framework using isotopic signatures to determine proportional contributions of different water sources to plant water uptake
Mancos Shale
age-detrended growth
Growth measurements adjusted to remove the effect of age-dependent growth patterns, allowing isolation of environmental factors on growth
establishment success
The ability of young trees to successfully establish and survive in a given environment
internode length
The distance between branch whorls on conifers, used to measure annual growth
structure from motion photogrammetry
Technique using overlapping images from different perspectives to construct 3D models of forest structure
LiDAR
Light detection and ranging technology using laser pulses to create detailed 3D maps of vegetation structure
