The complex ecological interactions that structure natural communities are shaped by organismic effects on external environments (habitat construction) and by individual phenotypic adjustments (eco-devo responses). This chapter examines the community-level consequences of organismic impacts on shared resources and conditions, and of plastic trait expression. An initial section introduces the context dependence of ecological interactions. The next section explains how both habitat construction and eco-devo responses contribute to the community properties of functional diversity and complementarity. Examples illustrate the roles of species-specific environmental effects, ecological facilitation, and trait-mediated interactions such as plastic (facultative) character displacement. The chapter goes on to discuss the community consequences of habitat construction through two detailed case studies, reef-building corals and native plants, noting the impacts of coral bleaching and plant invasions. A second pair of case studies examines the community consequences of trait plasticity, focusing on plastic aspects of plant–pollinator mutualisms and on induced plant defenses.

Keywords: niche construction; ecosystem engineers; phenotypic plasticity; facilitation; functional complementarity; trait-mediated interactions; coral reefs; invasive plants; plant–pollinator interactions; induced defenses
