(A) Seven ecosystems with foundation species were sampled: coastal (seagrass, blue mussel, cordgrass), freshwater (watermilfoil, water-starwort) and terrestrial (Spanish moss, marram grass). (B) Food webs were constructed for both bare and foundation species-dominated replicate areas. (C) From each foundation species structured-food web, nodes (species) were randomly removed until the s…

Two important measures ecologists use to describe the composition of a community are species richness and relative abundance (or species evenness). In general, ecologists think that more diverse ecological communities are more stable (that is, more able to recover after a disturbance) than less diverse communities.

This scale-dependent process can be described with different diversity metrics, some of which we will explore in this chapter; others will be introduced later.

Ecologists study the organization and function of communities from the scale at many spatial and temporal scales. Communities are complex systems that can be characterized by community structure (the number and size of populations and their interactions) and community dynamics (how the members and their interactions change over time). Scientists study ecology at the community level to understand how interactions between species and
