To disentangle the mechanisms producing the biological diversity seen in nature, ecologists increasingly seek to integrate ecology and evolution (Jetz et al., 2012;McGill et al., 2019;Wiens & Donoghue, 2004). Mapping traits onto phylogenies is essential for such integration, as mapping traits reveals the rates and tempo of evolution of behavioral, morphological, and ecological characteristics (Bollback, 2006). Knowledge of trait evolution has often been applied to evaluate the evolutionary mechanisms producing, for example, the appearance of ecological innovations and the bursts behind evo-

We evaluated whether evolution is faster at ecotones as niche shifts may be needed to persist under unstable environment. We mapped diet evolution along the evolutionary history of 350 sigmodontine species. Mapping was used in three new tip-based metrics of trait evolution–Transition Rates, Stasis Time, and Last Transition Time–which were spatialized at the assemblage level (aTR, aST, aTL). Assemblages were obtained by superimposing range maps on points located at core and ecotone of the 91 South American ecoregions. Using Linear Mixed Models, we tested whether ecotones have species with more changes from the ancestral diet (higher aTR), have maintained the current diet for a shorter time (lower aST) and have more recent transitions to the current diet (lower aLT) than cores. We found higher aTR, aST and aLT at ecotones than at cores. Although ecotones are more heterogeneous, both environmentally and in relation to selection pressures they exert on organisms, ecotone species change little from the ancestral diet as generalist habits are necessary toward feeding in ephemeral environments. The need to incorporate phylogenetic uncertainty in tip-based metrics was evident from large uncertainty detected. Our study integrates ecology and evolution by analyzing how fast trait evolution is across space.

Evoregions: Mapping Shifts in Phylogenetic Turnover Across Biogeographic Regions

Abstract: Biogeographic regionalization offers context to the geographical 1 0 evolution of clades. The positions of bioregions inform both the spatial location of 1 1 clusters in species distribution and where their most important boundaries are.
