“…We also tested for differences in patterns of morphological divergence linked to sympatry across groups with different dietary adaptations, as they relate to group-specific patterns consistent with CD or CC in noctilionoid bats. We predicted that: (i) sympatry would have a negative significant effect on morphological divergence, consistent with CC in Neotropical bats (Shi et al, 2018;Verde Arregoitia et al, 2018), (ii) the effect of sympatry on morphological divergence would vary across dietary groups, reflecting differences in the evolutionary trajectories of each group, and (iii) our results would be consistent across all-species (macro scale) and sister-species only (micro scale), as previously reported in bats (Shi et al, 2018).…”

“…Interestingly, our results also supported the presence of CC in phytophagous (frugivorous and nectarivorous) bats, exhibiting a negative correlation with coexistence. Character convergence has previously been reported in phytophagous phyllostomid bats (Shi et al, 2018; Verde Arregoitia et al, 2018). Evidence of morphological CC in phytophagous phyllostomid bats suggests ecological competition was not a driver of their morphological diversification.…”

“…Future studies could expand this framework to include other bat lineages to further test whether ecological competition played a role on chiropteran evolution. It is also worth mentioning that CC to reduce competition can differentially affect a variety of traits (Pfennig & Pfennig, 2010; Tobias et al, 2014), which could partially explain mixed findings across previous studies and ours (Campbell et al, 2007; Dragu et al, 2019; Shi et al, 2018; Verde Arregoitia et al, 2018). Exploring CC along multiple axes of adaptation (e.g.…”

“…Indeed, to date the study of morphological evolution in noctilionoid bats has tended to explore intrinsic and extrinsic and biological and ecological drivers of diversification in isolation from one another (Dragu et al, 2019; Dumont et al, 2012; Freeman, 1988; Santana et al, 2012; Shi et al, 2018; Verde Arregoitia et al, 2018), overlooking the unique evolutionary trajectories of different bat dietary groups and/or clades. For example, phytophagous noctilionoid bats diversified in the Neotropics throughout the Cenozoic without any other competing tetrapod group (Arita et al, 2014; Rojas et al, 2016).…”

AimThe remarkable ecomorphological diversity of the bat superfamily Noctilionoidea is the result of a diet‐mediated adaptive radiation. Stemming from a putatively insectivorous ancestor, noctilionoid bats diversified to adapt to the widest range of dietary ecologies among mammals. The high concentration of noctilionoid diversity in the Neotropics raises the question as to whether competitive ecological interactions influenced their diversification. However, patterns of morphological diversification along gradients of coexistence in Noctilionoidea are understudied. Here, we assessed the effect of dietary adaptations on patterns of morphological divergence associated with coexistence in noctilionoid bats.LocationThe Americas and the Caribbean.TaxonBat superfamily Noctilionoidea.MethodsUsing a set of five dental morphological traits and a sample of 108 species, we quantified morphological distances between noctilionoid species pairs to reveal patterns of morphological divergence along gradients of range overlap and dietary similarity. We incorporate phylogenetic information to control for the effects of species' relatedness on morphological distances.ResultsOverall, we found a significant association between morphological divergence, coexistence and diet. Decomposing the correlation between morphological divergence and sympatry across dietary groups, our results revealed distinctive patterns consistent with both character convergence and divergence. Specifically, we found evidence of character convergence in herbivorous species and character divergence in omnivorous species.Main ConclusionsOur results indicate that the morphological diversification of noctilionoid bats followed parallel evolutionary trajectories of directional (both divergent and stabilising) and nonselective evolution linked to dietary adaptations.

“…Las tierras bajas de la DN se inundaron a principios del Pleistoceno (Harmon, 2005); por ello, la región montañosa entre Costa Rica y Panamá debió ser inaccesible para S. hondurensis. Cabe recordar que tanto los datos genéticos como los datos morfológicos disponibles en la literatura, respaldan la presencia de S. hondurensis desde México hasta la región montañosa central de Honduras (Clare et al, 2011;Iudica, 2000;Jones y Phillips, 1964;Miranda, 2012;Velazco y Patterson, 2013;Verde-Arregoitia et al, 2018;Torres-Morales et al, en prensa), mientras que los datos genéticos entre Costa Rica y Panamá que se pensaba correspondían a S. ludovici (de la que S. hondurensis se consideraba sinónima), actualmente corresponden a S. burtonlimi especie hermana de S. hondurensis (Velazco y Patterson, 2013, 2014.

ResumenSturnira hondurensis es una de las 2 especies de murciélagos del género que se distribuyen desde Centroamérica hasta el norte de México; recientemente fue reconocida a nivel de especie, pero sus límites de distribución geográfica son inciertos. Con la finalidad de conocer estos límites, se modeló su nicho ecológico para determinar su distribución geográfica actual. Se encontró que para S. hondurensis, el límite sur se localiza en la Cordillera Central de Panamá, con una disyunción en la depresión de Nicaragua, mientras que hacia el norte, los límites se encuentran desde las sierras Madre Occidental y Madre Oriental en México, con excepción de la península de Yucatán.

Competition has long been recognized as a central force in shaping evolution, particularly through character displacement. Yet research on character displacement is biased, as it has focused almost exclusively on pairs of interacting species while ignoring multispecies interactions. Communities are seldom so simple that only pairs of species interact, and it is not clear whether inferences from pairwise interactions are sufficient to explain patterns of phenotypes in nature. Here, we test for character displacement in a natural system of freshwater fishes in western Mexico that contains up to four congeneric species of the genus Poeciliopsis. We analyzed body shape differences between populations with different numbers of competitors while accounting for confounding environmental variables. Surprisingly, we found evidence for convergent character displacement in populations of P. prolifica, P. viriosa, and P. latidens. We also found that the convergence in body shape was not consistently in the same direction, meaning that when three or more competitors co-occurred, we did not find more extreme body shapes compared with when there were only two competitors. Instead, when three or more competitors co-occurred, body shape was intermediate between the shape found with a pair of species and the shape found with no competitor present. This intermediate shape suggests that evolution in multispecies communities likely occurs in response to several competitors rather than to simple pairwise interactions. Overall, our results suggest that competition among multiple species is more complex than simple pairwise competitive interactions.
