“…We obtained body size data, in grams, for 751 of 799 bat species plus a few distinct subspecies (making up 804 bat terminals) represented in our phylogenetic hypothesis, from specific sources (Schober and Grimmberger 1997;Bonaccorso 1998;Churchill 1998;Smith et al 2003;Gannon et al 2005;Goodman et al 2006;Aguirre 2007;Decher and Fahr 2007;dos Reis et al 2007;Garbutt 2007;Pacheco et al 2007;Zhang et al 2007;Magalhaēs and Costa 2009;Lim et al 2010;Harvey et al 2011;Mendes 2011;Threlfall et al 2011;Hasan et al 2012;Patterson and Webala 2012;Thong et al 2012;Kruskop 2013;Monadjem et al 2013;Dammhahn and Goodman 2014;Huang et al 2014;Kawai et al 2014;Lu et al 2014;Sedlock et al 2014 ; Table SI.1).

Evolution of Body Mass in Bats: Insights from a Large Supermatrix Phylogeny

Bats are atypical small mammals. Size is crucial for bats because it affects most aerodynamic variables and several key echolocation parameters. In turn, scaling relationships of both flight and echolocation have been suggested to constrain bat body size evolution. Previous studies have found a large phylogenetic effect and the inclusion of early Eocene fossil bats contributed to recover idiosyncratic body size change patterns in bats. Here, we test these previous hypotheses of bat body size evolution using a large, comprehensive supermatrix phylogeny (+800 taxa) to optimize body size and examine changes reconstructed along branches. Our analysis provides evidence of rapid stem phyletic nanism, an ancestral value stabilized at 12 g for crown-clade Chiroptera followed by backbone stasis, low-magnitude changes inside established families, and massive body size increase at accelerated rate in pteropodid subclades. Total variation amount explained by pteropodid subclades was 86.3%, with most changes reconstructed as phyletic increases but also apomorphic decreases. We evaluate these macroevolutionary patterns in light of the constraints hypothesis, and in terms of both neutral and adaptive evolutionary models. The reconstructed macroevolution of bat body size led us to propose that echolocation and flight work as successive, nested constraints limiting bat evolution along the body size scale.
