“…2014), its forests are in critical danger as they have only 16 % of their natural vegetation intact, 4 % semi-natural vegetation, and 80 % has been transformed (Etter et al, 2017;Latorre et al, 2014). The main activities of transformation and loss of habitat are of anthropic origin, such as large-scale agricultural crops (silvopastoral systems and monocultures), extensive livestock, illicit crops, and rapid urban growth (Hernández et al, 2021;Velosa et al, 2018).…”

Introduction: The effects of habitat transformation have been widely studied and the effects are well-known at different levels of biological organization. However, few studies have focused on responses to this process at the level of multiple taxa in diverse taxonomic and functional groups. Objective: To determine variations in insect assemblages in a landscape mosaic of Colombian Orinoquia foothills. Methods: We assessed amount of natural habitat and landscape composition in four types of vegetation of Colombian foothills in the Orinoquia region (three each on the highest and lowest rain periods). We collected butterflies with hand nets and used baited pitfall traps for dung beetles and ants. Results: Precipitation caused species turnover to different degrees in the three taxa; and connectivity between different types of plant cover, amount of natural habitat, and pasture type play a fundamental role in the maintenance of insect biodiversity in modified ecosystems of the foothills of the Colombian Orinoquia. However, the assemblages responded differently to habitat change. Conclusions: While connectivity, natural habitat, and pastures affect insect assemblages, the lack of a common pattern shows that several insect groups must be studied for monitoring biodiversity and for conservation.

“…Además de los ambientes naturales, en Colombia se han registrado murciélagos en ambientes rurales y urbanos (Pérez-Torres et al, 2009;Calongue et al, 2010;Sánchez, 2011;Garcés-Restrepo et al, 2016;Ramírez-Mejía et al, 2020), y posiblemente se encuentran murciélagos en todos los ambientes dominados por los humanos del país. Aunque buena parte de la Orinoquía y la Amazonía no ha sido examinada con detalle, la información disponible sugiere que sus comunidades de murciélagos son diversas, y particularmente hacia el piedemonte pueden incluir un alto número de especies (Rivas-Pava et al, 1996;Estrada-Villegas & Ramírez, 2013;Ramírez-Chaves et al, 2013;Sánchez, 2017;Morales-Martínez et al, 2018;Hernández-Leal et al, 2021).…”

La ganadería es importante para la economía colombiana y fundamental para la nutrición de su población, y esto también es cierto para sus regiones orinoquense y amazónica. Desafortunadamente, la ganadería ha tenido consecuencias ambientales negativas, incluyendo pérdidas de biodiversidad, y dichos impactos negativos tienen el potencial de comprometer la misma producción ganadera. Por ello la necesidad de incorporar la biodiversidad en esta actividad en esas regiones naturales ricas en biodiversidad. Con esto en mente, se revisó información relacionada con los beneficios prestados por los murciélagos en diferentes sistemas agrícolas y la interacción ganadería-murciélagos. La información consultada indica que los murciélagos son valiosos controladores de insectos plaga en múltiples sistemas agrícolas y hay ejemplos que sugieren que también lo hacen en sistemas ganaderos. Dada la riqueza de murciélagos insectívoros en la Orinoquia y Amazonia, hay un alto potencial para que ellos se conviertan en aliados de la ganadería en estas regiones. Para ello se recomienda: 1) realizar campañas pedagógicas para mejorar la actitud de los ganaderos hacia los murciélagos, 2) mantener o establecer controles específicos a los murciélagos vampiros, 3) analizar la dieta de murciélagos que pueden consumir especies plaga, 4) desarrollar estudios que permitan identificar cómo diferentes sistemas de producción y manejos del paisaje afectan la actividad y calidad de hábitat para los murciélagos, y 5) desarrollar experimentos para evaluar la adición de refugios artificiales para los murciélagos y experimentos de exclusión para determinar su valor para la ganadería.

“…Bats are unique in that they are the only flying mammals and are the dominant aerial nocturnal vertebrates. In the Neotropics, there is a high diversity of species and trophic groups [18][19][20][21]. Their feeding strategies are associated with numerous physiological and morphological traits that facilitate the exploitation of food resources, and they have a diverse cranial morphology that appears to be related to changes in the bite force (BF) [22,23].…”

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.
