Metacommunity theory is an extension of metapopulation theory with the goal of understanding how ecological communities vary through space and time. One off‐shoot of metacommunity theory deals with understanding how community structure varies along biotic or environmental gradients. The Elements of Metacommunity Structure framework is a three‐tiered analysis of metacommunity structure that enables the user to identify metacommunity properties that arise in site‐by‐species incidence matrices. These properties can then be related to underlying variables that influence species distributions. The EMS framework is now implemented in metacom, an open source R package that allows for the analysis and plotting of metacommunities.
