“…Our study focused on reconstructing the likely diet of the extinct phyllostomid N. magdalenensis by comparing its dental morphology with that of modern members of this family. Phyllostomidae is recognized as the greatest adaptive radiation of any mammalian family (Monteiro and Nogueira 2011; Rossoni et al 2017; Fleming et al 2020). Adoption of novel dietary niches and morphological innovation have been linked to the diversification of this family (Freeman 2000; Dumont et al 2012; Rossoni et al 2019; Hedrick et al 2020).…”

“…Adoption of novel dietary niches and morphological innovation have been linked to the diversification of this family (Freeman 2000; Dumont et al 2012; Rossoni et al 2019; Hedrick et al 2020). Representing less than 15% of modern global bat diversity (~200 species), phyllostomid bats have successfully colonized almost every dietary niche found in the entire chiropteran order, with the exception of piscivory (Monteiro and Nogueira 2011; Rossoni et al 2017; Fleming et al 2020). Previous studies have suggested that different phyllostomid clades adapted to nectarivory convergently, reflecting the ecomorphological evolvability in phyllostomids (Datzmann et al 2010; Rojas et al 2016).…”

With 14 species recorded, the Miocene La Venta bat fauna is the most diverse bat paleocommunity in South America. It includes the oldest plant-visiting bat in the New World and some of the earliest representatives of the extant families Phyllostomidae, Thyropteridae, and Noctilionidae. La Venta's Notonycteris magdalenensis is an extinct member of the subfamily Phyllostominae, a group of modern Neotropical animalivorous bats, and is commonly included in studies of the evolution of Neotropical bats, but aspects of its biology remain unclear. In this study, we used multivariate dental topography analysis (DTA) to reconstruct the diet of N. magdalenensis by quantitatively comparing measures of molar complexity with those of 25 modern noctilionoid species representing all major dietary habits in bats. We found clear differences in molar complexity between dietary guilds, indicating that DTA is potentially an informative tool to study bat ecomorphology. Our results suggest N. magdalenensis was probably an omnivore or insectivore, rather than a carnivore like its modern relatives Chrotopterus auritus and Vampyrum spectrum. Also, we reconstructed the body mass of N. magdalenensis to be ~95 g, larger than most insectivorous bats, but smaller than the largest carnivorous bat (V. spectrum). Our results confirm that N. magdalenensis was not a specialized carnivore. It remains to be demonstrated that the specialized carnivory ecological niche was occupied by the same lineage of phyllostomines from at least the middle Miocene. Combining our diet and body-mass reconstructions, we suggest that N. magdalenensis exhibits morphological pre-adaptations crucial for the evolution of specialized carnivory.

“…However, insectivorous phyllostomids evolved to occupy different regions of morphospace than other noctilionoid insectivorous bats in the Americas (Hedrick et al, 2019). Moreover, many insectivorous noctilionoids tend to have foraging strategies specialised for substrate gleaning, whereas other insectivorous bats in the Americas tend to specialise for aerial hawking (Fleming et al, 2020; Jones et al, 2016; Norberg & Rayner, 1987). While the role of antagonistic interactions between different insectivorous bat groups in the Americas during their evolution has been discussed (Imlau‐Cardoso et al, 2022; Ramos Pereira & Palmeirim, 2013), future studies focussing on exploring the interdependence in the morphological evolution of different insectivorous bats in the Americas could shed light on the role of ecological interactions during bat diversification.…”

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.

“…We analyzed the influence of niche evolution and dispersal limitation on the distribution of species diversity of Phyllostomidae, a species-rich and ecological diverse family of bats. Phyllostomid bats are predominantly distributed in the Neotropics, from California to northern Argentina and Chile (Fleming et al 2020). The family has 222 known species (Simmons and Cirranello 2020), displaying a large array of dietary and morphological specializations to feed on fruits, nectar, and other parts of plants, as well as on insects, vertebrates, and blood (Monteiro and Nogueira 2011, Baker et al 2012, Rossoni et al 2019, Fleming et al 2020.…”

The imprint left by niche evolution on the variation of biological diversity across spatial and environmental gradients is still debated among ecologists. Furthermore, understanding to what extent dispersal limitation may reinforce or blur such imprint is still a gap in the ecological knowledge. In this article we introduce a simulation approach coupled to approximate Bayesian computation (ABC) that parameterizes both the adaptation rate of species' niche positions over the evolution of a monophyletic lineage and the intensity of dispersal limitation associated with the variation of species alpha diversity among assemblages distributed across spatial and environmental gradients. The analytical tool was implemented in the R package 'mcfly' (www.r‐project.org). We evaluated the statistical performance of the analytical framework using simulated datasets, which confirmed the suitability of the analysis to estimate adaptation rate parameter but showed to be less precise in relation to the dispersal limitation parameter. Also, we found that increased dispersal limitation levels improved the parameterization of the adaptation rate of species' niche positions in simulated datasets. Further, we evaluated the role played by niche evolution and dispersal limitation on species alpha diversity variation of Phyllostomidae bats across the Neotropics. The framework proposed here shed light on the links between niche evolution, dispersal limitation and gradients of biological diversity, and thereby improved our understanding of evolutionary imprints on current biological diversity patterns.
