Bridging macroecology and macroevolution in the radiation of sigmodontine rodents

Renan Maestri, André L. Luza, Sandra M. Hartz, Thales R.O. De Freitas & Bruce D. Patterson
Investigations of phenotypic disparity across geography often ignore macroevolutionary processes. As a corollary, the random null expectations to which disparity is compared and interpreted may be unrealistic. We tackle this issue by representing, in geographical space, distinct processes of phenotypic evolution underlying ecological disparity. Under divergent natural selection, assemblages in a given region should have empirical disparity higher than expected under an evolutionarily-oriented null model, while the opposite may indicate constraints on phenotypic evolution. We...
