Title

Multitrophic interactions within and across ecosystems

Abstract

Identifying the drivers and consequences of multitrophic interactions is critical to understanding how ecosystems function and respond to perturbations. Multitrophic interactions range from the simple to the highly complex and vary in scale from organism to ecosystem.  Here I provide examples of how multitrophic interactions regulate processes driving biogeochemical cycles and community dynamics across this spectrum of ecological complexity and spatial scale, and how they respond to management interventions and components of climate change. I will give examples of interactions connecting soil organisms, plants, herbivores and seabirds.
