A plethora of different theories, models, and concepts make up the
field of community ecology. Amid this vast body of work, is it
possible to build one general theory of ecological communities?
What other scientific areas might serve as a guiding framework? As
it turns out, the core focus of community ecology--understanding
patterns of diversity and composition of biological variants across
space and time--is shared by evolutionary biology and its very
coherent conceptual framework, population genetics theory. The
Theory of Ecological Communities takes this as a starting point to
pull together community ecology's various perspectives into a more
unified whole. Mark Vellend builds a theory of ecological
communities based on four overarching processes: selection among
species, drift, dispersal, and speciation. These are analogues of
the four central processes in population genetics theory--selection
within species, drift, gene flow, and mutation--and together they
subsume almost all of the many dozens of more specific models built
to describe the dynamics of communities of interacting species. The
result is a theory that allows the effects of many low-level
processes, such as competition, facilitation, predation,
disturbance, stress, succession, colonization, and local extinction
to be understood as the underpinnings of high-level processes with
widely applicable consequences for ecological communities.
Reframing the numerous existing ideas in community ecology, The
Theory of Ecological Communities provides a new way for thinking
about biological composition and diversity.
