ABSTRACT: The study of functional diversity is a rapidly expanding area in ecology. We propose a workflow that can be used to examine changes in functional diversity with habitat disturbance by creating surface maps of functional diversity and suggest how this can be incorporated into land use management. We applied our new workflow to a forest beetle community of wood-boring beetle prey (Coleoptera: Cerambycidae) and their generalist beetle predators to examine changes in functional diversity with forest fragmentation. We predicted that habitat fragmentation would have a greater negative impact on predator beetle functional diversity than prey wood-borer functional diversity. Opposite to what we predicted, we found that the functional diversity of the prey was more negatively impacted by fragmentation than the predator functional diversity. Overall functional diversity was greatest with minimal forest fragmentation. Predator functional diversity was less restricted by habitat edge. The methods we developed are widely transferable to other communities, thus have broad implications in the development and application of functional diversity research. We propose that land management may be guided by revealing landscapes that are most appropriate for maximizing functional diversity of multiple communities or shifting the relative abundance within pest and beneficial functional groups with the use of three-dimensional plots or maps. Furthermore, this workflow can be applied to many other systems and used to drive policy decisions.
