Focusing on the ecological mechanisms that underpin ES delivery allows bundles of services to be identified, bridging a critical gap with management. target.onselectstart = disable_copy_ie; var elemtype = e.target.tagName; which of these scenarios describes all trophic cascades quizlet Long-term potentiation (LTP) is a persistent increase in synaptic strength following high-frequency stimulation of a chemical synapse. Biomass is simply the amount of matter that's stored in the bodies of a group of organisms. Climate change is having, and will continue to have, impacts on biogeochemical cycles, which will alter future impacts on climate and affect our capacity to cope with coupled changes in climate, biogeochemistry, and other factors.
