Species-area relationship
The positive relationship between species richness and the surveyed area, described by the power-law S=cA^z where c is the intercept and z measures the rate of community turnover
community composition
The identity and relative abundance of species within an ecological community
spatial clustering
Alpine plants growing in clumps with multiple species interacting in close proximity, affecting microhabitats and species interactions
trait filtering
Environmental processes that filter trait values admitted by changing abiotic and biotic conditions, maintaining trait distributions through phenotypic plasticity and local adaptation
herbivore preference
Selective feeding behavior of herbivores that favors certain plant traits or genotypes over others
phylogenetic distance
Evolutionary divergence time between species measured in millions of years, calculated from molecular phylogenetic reconstructions
facilitation
Constant Connectance in Space model
Model developed to determine LARs based on SAR and simple properties of food webs including species richness, number of links and connectance
temperature buffering
When clustered plants experience facilitative interactions that cause leaves to be cooler relative to surrounding soils
sex-specific climate response
Differential responses between sexes to environmental variation potentially creating imbalance in the frequency of males and females
