“…This is consistent with studies such as Aranguren et al [78], which proposed that N. albiventris can be considered a potential insect controller in disturbed areas close to dry forests in the Neotropics. The performance in the BF associated with the depth of the dentary and the biomechanical action of the jaw could be fundamental in the differences in foraging behavior, diet, and ecological niches within the sympatric species of Noctilio, Molossus, Molossops and Myotis [33,[76][77][78]. Because limited habitat or food availability drives interand intraspecific competition [63], such morphological differences may optimize the use of resources and reduce diet overlap in various species, thus facilitating their coexistence [79].…”

“…This measure reflects differences in the size and development of temporal muscle fibers [75], and larger temporal fibers are related to increased body size and BF, due to a positive relationship with muscle mass [23,33,[75][76][77].

In Neotropical bats, studies on bite force have focused mainly on differences in trophic ecology, and little is known about whether factors other than body size generate interspecific differences in bite force amongst insectivorous bats and, consequently, in their diets. We tested if bite force is related to skull morphology and also to diet in an assemblage of Neotropical insectivorous bats from tropical dry forests in the inter-Andean central valley in Colombia. It is predicted that the preference of prey types among insectivorous species is based on bite force and cranial characteristics. We also evaluated whether skull morphology varies depending on the species and sex. Cranial measurements and correlations between morphological variation and bite force were examined for 10 insectivorous bat species. We calculated the size-independent mechanical advantage for the mandibular (jaw) lever system. In all species, bite force increased with length of the skull and the jaw more than other cranial measurements. Obligate insectivorous species were morphologically different from the omnivorous Noctilio albiventris, which feeds primarily on insects, but also consumes fish and fruits. Our results show that bite force and skull morphology are closely linked to diets in Neotropical insectivorous bats and, consequently, these traits are key to the interactions within the assemblage and with their prey.

“…Estos resultados coinciden con los reportados por Ferguson et al (2003) para selvas de El Petén guatemalteco, García-Licona et al (2014), Esparza-Olguín y Martínez-Romero (2018) para selvas de la región de Calakmul y van Breugel et al (2006) para selvas de Marqués de Comillas, Chiapas. La heterogeneidad en la estructura horizontal y vertical podría contribuir a la gran cantidad de murciélagos que se albergan en la cueva, al considerar que se ha reportado que la abundancia y diversidad de murciélagos se relaciona de forma positiva con la heterogeneidad y diversidad florística en bosques, además de influir en su conducta particularmente en lo relacionado con el vuelo (Aranguren et al 2011, Jung et al 2012. Los valores de área basal reportados en este estudio son en general menores a los reportados por otros autores para selvas de la región de Calakmul (García-Licona et al 2014, Esparza-Olguín y Martínez-Romero 2018) quienes reportan valores entre 22.6 y 37.4 m 2 ha −1 .…”

RESUMEN. La diversidad de la vegetación aledaña al refugio El Volcán de los Murciélagos no ha sido descrita, por lo que el objetivo fue determinar su composición florística, diversidad estructural y la biomasa almacenada. Se establecieron ocho sitios de muestreo, cercanos y lejanos al borde. Se censaron 2 844 individuos en un área de muestreo de 5 000 m 2. La riqueza de especies fue de 84, distribuidas en 34 familias. Las especies más abundantes fueron Croton oerstedianus, Eugenia winzerlingii y Drypetes lateriflora, siendo Astronium graveolens la única especie en la NOM-059-SEMARNAT-2010. El área basal varió entre 9.55 y 26.05 m 2 ha −1 y la densidad entre 4 288 y 8 272 ind ha −1. La estructura horizontal y vertical, presentan un patrón en forma de J-invertida. Los valores de diversidad estructural tienen una relación positiva con la acumulación de biomasa, que varió entre 4.23 y 51.95 Mg ha −1. Los resultados indican que la heterogeneidad y diversidad de la vegetación circundante a la cueva El Volcán de los Murciélagos, constituyen características del hábitat que influyen en las especies de murciélagos que habitan la cueva. Las condiciones estructurales y la diversidad correlacionados con la acumulación de biomasa, refuerzan la necesidad de generar estrategias de conservación para este refugio multiespecífico.

“…Likewise, frugivores such as Artibeus lituratus (Olfers 1818), Carollia perspicillata (Linnaeus 1758) and Sturnira lilium (E. Geoffroy 1810) have preference for Ficus, Piper and Solanum, respectively (Fleming 1986;Saldaña-Vázquez et al 2019), yet they complement their diets by consuming other fruits, nectar and insects (Giannini and Kalko 2004). However, few cases of insectivorous bats that consume plant items have been reported (Aranguren et al 2011;Felix et al 2013;Novaes et al 2015).…”

“…There is increasing evidence that bats can perform multiple functions other than the role assigned to their guild (Aranguren et al 2011;Frick et al 2013;Novaes et al 2015;Castillo-Figueroa 2020b). This is especially surprising in species with highly specialized diets, as is the case of insectivores that present particular morphological, physiological and behavioral adaptations to consume animal food items.…”

First evidence of frugivory in Gardnerycteris crenulatum (Chiroptera: Phyllostomidae)

Gardnerycteris crenulatum is a bat species restricted to South America, being particularly rare in lowland rainforests. It is characterized by a diet composed mainly of arthropods and small vertebrates, with no confirmed evidence of fruit consumption. Here, we provide the first records of seeds in the diet of G. crenulatum. The seeds were found in the feces of two individuals captured in late-successional forests in the Colombian Amazon (one pregnant female and one adult male), that belonged to Piper sp. (n = 125) and Cecropia engleriana (n = 3). In germination experiments, only Piper seeds germinated (8%). Insectivores can potentially perform other functions than the role assigned to their corresponding guild. More research is needed on the natural history and ecology of G. crenulatum to elucidate its possible role as seed disperser.
