  Whether or not biodiversity dynamics tend toward stable equilibria remains an
unsolved question in ecology and evolution with important implications for our
understanding of diversity and its conservation. Phylo/population genetic
models and macroecological theory represent two primary lenses through which we
view biodiversity. While phylo/population genetics provide an averaged view of
changes in demography and diversity over timescales of generations to
geological epochs, macroecology provides an ahistorical description of
commonness and rarity across contemporary co-occurring species. Our goal is to
combine these two approaches to gain novel insights into the non-equilibrium
nature of biodiversity. We help guide near future research with a call for
bioinformatic advances and an outline of quantitative predictions made possible
by our approach.
