Concepts

SPAD measurement of leaf chlorophyll concentration indicating photosynthetic capacity

Chemical composition of plant litter that determines its decomposability, typically characterized by C:N ratios and lignin content

Distribution of metabolic rates over individuals in a community, obtained by summing over abundance

Loss of cellular electrolytes through compromised cell membranes, used as indicator of heat stress damage

Ability of plants to survive exposure to elevated temperatures, measured as lethal temperature causing 50% electrolyte leakage (LT50)

Distinct layers in soil profile with different physical and chemical properties

The rate at which temperature decreases with elevation, typically expressed as degrees Celsius per kilometer
