Concepts
21 concepts
specific leaf area
The ratio of leaf area to dry mass, often associated with dry conditions as it reduces surface area and water loss from the leaf
aboveground primary productivity
Net production of plant biomass above ground surface measured as standing crop minus losses to herbivores
environmental variability
Temporal variation in environmental conditions measured as standard deviation of temperature and vegetation indices
stamen length
body size variation
Variation in organismal body size both within and between species, influenced by environmental and genetic factors
functional traits
Measurable morphological and physiological characteristics of organisms that influence ecological performance
species range limits
The geographic or environmental boundaries beyond which species cannot persist, potentially influenced by biotic interactions
body size
Rensch's Rule
leaf economics spectrum
Describes consistent and strong correlations among plant functional traits reflecting the ecological tradeoffs and constraints of plants around resource use
phenophases
Distinct phases of bee flight period: emergence from nests, timing of peak abundance of foragers, and senescence
stomatal conductance
environmental filtering
litter quality
root mass depth distributions
NPP
LM
space-for-time substitution
Assumption that spatial differences in environmental conditions can predict temporal responses to environmental change
nonlinear process interactions
wood traits
Gloger's rule
A relationship between plumage coloration and climate variation, predicting that darker coloration due to pigmentation occurred in warmer, more humid tropical regions while lighter colors occurred in ...
