Bats (Chiroptera: Noctilionoidea) Challenge a Recent Origin of Extant Neotropical Diversity.
Biogeographic analyses revealed the importance of the Neotropics in noctilionoid diversification, and the critical role of dispersal, and simulations modeling constant speciation and extinction rates for the phylogeny systematically showed more speciation events in the Quaternary. Expand
When did plants become important to leaf‐nosed bats? Diversification of feeding habits in the family Phyllostomidae
It is proposed that during the evolution of phyllostomids switches to new feeding mechanisms to access to abundant and/or underexploited resources provided selective advantages that favoured the appearance of ecological innovations independently in different lineages of the family. Expand
The role of frugivory in the diversification of bats in the Neotropics
The direction of the relationship of intrinsic factors (specialization for frugivory and body size) with diversification of noctilionoid bats depends on the biogeographical context, whereas the direction ofthe relationship of extrinsic factors (geographical range and number of ecoregions) with diverification is consistent in both mainland and the West Indian lineages.

Evolving through day and night: origin and diversification of activity pattern in modern primates
The present research contributes to further disentangle the adaptive role of activity patterns in primate evolution, suggesting a low flexibility of diurnal and nocturnal patterns and the key importance of cathemeral activity as transitional state to shift between more specialized activity patterns. Expand
Eating down the food chain: generalism is not an evolutionary dead end for herbivores.
It is shown that analysing ecological traits and diversification requires accounting for macroevolutionary regimes and within- and between-clade variation in evolutionary rates, and overcomes the high false-positive rates of other methods and illuminates the roles of herbivory and specialisation in speciation.

Breeding system and pollination by mimicry of the orchid Tolumnia guibertiana in Western Cuba
The behavior, preferences and movement patterns of Centris bees among these plants, as well as the morphological data, suggest that, as previously thought, flowers of T. guibertiana mimic the Malpighiaceae S. diversifolium, but orchid pollination in one of the studied populations appears to depend also on the presence of O. agrophylla.

Associations between sex-organ deployment and morph bias in related heterostylous taxa with different stylar polymorphisms.

Striking variation in the expression of heterostyly in Glandora and Lithodora is associated with biased morph ratios, which probably result from pollinator-mediated mating asymmetries within populations. Expand
A meta-analysis of the effects of habitat loss and fragmentation on genetic diversity in mammals

- 1 January 2019
A metaanalysis is conducted to test if genetic diversity of mammalian populations that live in fragments is lower than those living in continuous habitats and to explore which species traits could be related with the observed patterns, which allow a better understanding of which mammalian species are more susceptible to the negative effects of habitat loss and fragmentation.

Bayesian hierarchical models suggest oldest known plant-visiting bat was omnivorous

This is the first study to corroborate with fossil data that highly specialized nectarivory in bats requires an omnivorous transition and develop Bayesian models to infer skull length based on dental measurements. Expand
Breeding system and factors limiting fruit production in the nectarless orchid Broughtonia lindenii.
Considering that this orchid completely lacks nectar and that the local assemblage of pollinators and predators influenced its reproduction, a minor importance of resource constraints in this epiphyte (with long-lasting reserve structures) is confirmed at least for a short time. Expand
