foundation species
two-phase contrasts: shrub-open micro-environments

direct & indirect effects

regional gradient contrasting elevation & aridity

The hypothesis tested is that shrubs directly and indirectly buffer local changes in the microenvironment thereby functioning as refuges for other species within arid and semi-arid regions subject to dramatic
global change drivers.

plants & animals respond to shrubs in arid ecosystems

macro-differences = regional gradient

foundation species respond to macro-climate

however, foundation species modify micro-environmental conditions

two-phase micro contrasts important to animals

two-phase micro contrasts important to other plant species

species-specific responses to desert micro-environments

amplitude of change
biomagnification
scale
loss of interactions can precede loss of species
