Community ecology studies the patterns of changes in biodiversity, species structure, and the number of individual populations in a spatial and temporal aspect. The article discusses some modern theories of community ecology (neutral theory, patch dynamics, M. Vellend's ideas about four basic processes in communities similar to processes of population genetics [selection, drift, dispersal, selection], etc.).

In most places on Earth, many similar species are found coexisting. This key observation is often explained in terms of ecological differences in how species interact with their shared environment, that is, in terms of their niche differences. Niche differences can to lead to stable coexistence in contrast to the ecological drift predicted by the neutral theory of community ecology. Coexistence becomes stabilized as density feedback within species is strengthened relative to density feedback between species. Coexistence is reflective of two distinct niche comparisons, niche overlap, and species relative average fitness. In general, low niche overlap (dissimilarity in use of the environment) and similar average fitnesses (similar average performance) favor coexistence. For a unified theory of species coexistence, it is shown how the Lotka–Volterra competition model can reflect and quantify several types of niche comparison, including comparisons of resource use, susceptibility to natural enemies, and temporal variation in activity.

Community Ecology provides a broad, up-to-date coverage of ecological concepts at the community level and is suitable for advanced undergraduates, graduate students, and ecological researchers. The field of community ecology has undergone a transformation in recent years, from a discipline largely focused on processes occurring within a local area to a discipline encompassing a much richer domain of study, including the linkages between communities separated in space (metacommunity dynamics), niche and neutral theory, the interplay between ecology and evolution (eco-evolutionary dynamics), and the influence of historical and regional processes in shaping patterns of biodiversity. To fully understand these new developments, however, students continue to need a strong foundation in the study of species interactions, and how these interactions are assembled into community modules and ecological networks. Trait-based assembly rules are presented as another approach to understanding community assembly, especially for real-world communities that may contain hundreds of species. This new edition fulfils the book’s original aims, both as a much-needed up-to-date and accessible introduction to modern community ecology, and in identifying the important questions that are yet to be answered. This research-driven textbook introduces state-of-the-art community ecology to a new generation of students, adopting reasoned and balanced perspectives on as-yet-unresolved issues. Pictures and graphics throughout the text allow students to visualize advanced concepts.
