“…The dispersion of pioneer plants such as Solanum, Cecropia, and Ficus, shows the importance of bats in the succession processes in different environments (Garcia et al 2000;Muller & Reis 1992). The PERMANOVA results did not indicate differences in the seasonal analyses, but it is important to highlight that other studies revealed higher consumption in rainy periods, when food supply sources greatly increase, especially of Piperaceae species (Passos et al 2003;Mello et al 2004) We found that the richness of fruits consumed by bats was greater than that found in anthropized areas of Cerrado (Martins et al 2014;Torres et al 2018), but it was lower than that recorded in preserved areas of the Atlantic Forest (Laurindo et al 2018). Those results were expected because warmer and humid tropical areas usually present a greater diversity of fleshy fruits (Chen et al 2017).…”

Fruit bats have a high seed dispersal capacity contributing to the establishment of numerous plant species. In this work we examined the frugivorous diet of phyllostomid bats in the Cavernas do Peruaçu National Park, north of Minas Gerais, Brazil, an ecotone region of Caatinga and Cerrado biomes. Four expeditions were carried out between December 2008 and November 2009, totalling 80 nights of sampling, to collect data and feces from captured bats. The highest number of fecal samples were provided by Artibeus planirostris and Carollia perspicillata. Four plant families were registered, the largest number for Cecropiaceae, followed by Solanaceae; Piperaceae, and Moraceae.

“…We found a change in the direction of the effect of forest cover on the abundance from the 0.5 km to the 1.25 km scale. This suggests that at local scales A. planirostris requires enough forest cover to provide roosting sites and food resources (Mendes et al 2016), whereas at the larger extent the forest cover may reduce its opportunity to exploit available fruit resources in the deforested matrix (Torres et al 2018). Besides, the negative relationship with grass cover at the largest scale, 2 km, suggests a detrimental effect of extremely deforested landscapes on the abundance even for long-distance dispersal bats such as A. planirostris (Meyer et al 2016).…”

Land-use intensification imposes selective pressures that systematically change the frequency of wild population phenotypes. Growing evidence is biased towards the comparison of populations from discrete categories of land uses, ignoring the role of landscape emerging properties on the phenotype selection of wild fauna. Across the largest urban-rural gradient of the Colombian Orinoquia, we measured ecomorphological traits of 216 individuals of the Flat-faced Fruit-eating Bat Artibeus planirostris, to evaluate the scale of effect at which landscape transformation better predicts changes in phenotype and abundance of an urban-tolerant species. Forest percentage at 1.25 km was the main predictor affecting abundance, wing aspect ratio, and body mass of this phyllostomid; but the direction of the effect differed between abundance and ecomorphological traits. Although landscape factors explained changes in the forearm length at all spatial scales, the effect was sex-dependent and the most important predictor was forest percentage at 0.5 km. Our results indicate that landscape elements and spatial scale interact to shape ecomorphological traits and the abundance of A. planirostris. Interestingly, the scale of effect was congruent among all biological responses. A pattern that likely arises since species’ abundance can reflect the variation on phenotype under different environmental filters across landscape scenarios.

“…Morphological traits of plants and frugivores such as fruit and seed sizes and bill gape are important factors defining fruit consumption by animals (Wheelwright 1985). Small fruits are accessible to a wider variety of frugivores and plants with this trait, as well as small seeds, tend to play a central role in communities (Torres et al 2018, Sebastián-González 2017, Vizentin-Bugoni et al 2021. Thus, outplanting of native plants with small fruits (and seeds) may be an interesting strategy to attract and support a greater diversity of frugivores.…”

The diversity of fruits and frugivorous species is especially high in tropical regions where frugivory and seed dispersal interactions are particularly critical for the structure and functioning of terrestrial communities. However, the increasing urbanization in tropical areas has caused profound landscape changes, affecting species interactions and associated ecosystems functions. Here, we present an overview of the studies on frugivory and seed dispersal in tropical urban areas, discussing emergent patterns and processes underlying plant-frugivore interactions as well as major research gaps. Our review highlights an uneven geographical distribution of studies, which are more frequent in the Neotropics in comparison to Indomalayan and Afrotropical regions. We found that in tropical urban areas: (i) the most frequently studied group are flying frugivores (birds and bats), (ii) fruits of Myrtaceae, Moraceae, and Arecaceae are most frequently reported as consumed by frugivores, (iii) introduced plants are often present in frugivores’ diets, and become more common with urbanization, (iv) frugivores niche breadths vary with seasonality in fruit availability, (v) a higher diversity of fruits are consumed by frugivores in (or near) habitats that preserve more natural characteristics, such as higher proportion of green areas. Since suitable habitats within cities are highly variable in size, shape, connectivity, patterns of human activity, vegetation management and socioeconomic contexts, we recommend future studies to sample gradients in such variables. Furthermore, as new urban areas are often planned in advance, ‘before-after impact’ studies may be particularly insightful to understand how frugivores respond to urbanization and how to create frugivore-friendly areas without promoting undesirable (invasive) plants. Although the scarcity of studies and their geographical bias limit generalizations across distinct tropical regions, based on our review we provide a preliminary list of broad recommendations of management practices towards creating biodiversity-friendly urban areas.
