The implications of food hardness for diet in bats

Summary 1.Neotropical bat communities are characterized by a broad species diversity, which can be achieved and maintained only through partitioning of the available resources. 2. Here patterns of trophic resource utilization within a single neotropical savanna bat community are investigated. Moreover, the physical properties of food items (i.e. hardness), its variation with food size, and whether food hardness differs between items consumed by the bats in this community are investigated experimentally. 3. The results show that food hardness increases with the size of the food item, and that distinct differences exist in the amount of force needed to crush different food items (beetles vs other insects vs fruits). 4. Using previously published data on bite forces from species in the same community it is explored whether food hardness may play a role in shaping the diets of the bats in the community. The combined data on bite forces and food hardness indicate that food hardness can both directly and indirectly limit dietary diversity in bats. 5.The results also indicate that dietary specialization may potentially result in a decrease in trophic breadth for some species through its effect on bite performance.

“…Although Artibeus, Carollia, and Glossophaga generally feed on plant sources, it is clear that they also frequently consume significant quantities of insects (Arata et al 1967, Fleming et al 1972, Howell 1974, Howell & Burch 1974, rev. by Rasweiler 1975, 1977, rev.…”

“…With the exception of the Sierra Nevada de Santa Marta, all localities fall within highly altered ecosystems (IAvH 2004). Vereda El Hormiguero (ICN 4398) is located in a sugar cane agricultural system, even at the time of the capture of the specimen (Arata et al 1967). San Juan de Rioseco (AMNH 69187) and Vereda La Huerta (MUD 587) are mountainous areas with a landscape composed of ranching pastures, small agricultural fields, and fragments of natural forests.…”

The Anoura geoffroyi species complex is composed of 3 large species: A. geoffroyi, A. peruana, and A. carishina. Several inconsistencies arise from the description of A. carishina, and given the lack of a comparison with the dentition and external characters of A. latidens, here we compare the taxonomic characters of these species. To understand the position of A. carishina in the morphospace occupied by large Anoura, we conducted a Principal Component Analysis on 12 craniodental and 11 external variables. We complement our results with further analysis of traits thought to be diagnostic for these species, including 1) an elliptical Fourier transformation analysis of the shape of the third upper premolar (P4), 2) a comparison of the area of the second (P3) and third (P4) upper premolars, and 3) a comparison of maxillary toothrow angles. We find that A. carishina is morphologically indistinguishable from A. latidens, and that there is broad overlap in morphology between A. latidens and A. geoffroyi. However several characters found in A. latidens are lacking in A. geoffroyi, including a triangular shape to the P4 caused by a medial-internal cusp enclosed by the base of the tooth, a lack of development of the anterobasal cusp in the P3, a smaller braincase, and a shorter rostrum. We reassess the distribution of Anoura latidens in Colombia, adding new records and correcting previously-published records that were misidentified. Overall, our results suggest that a stable taxonomy for the group should consider A. carishina as a junior synonym of A. latidens, and that, although A. latidens is distinguishable from A. geoffroyi, further genetic and taxonomic work is needed in to clarify species limits within the A. geoffroyi species complex.El complejo de especies Anoura geoffroyi se compone de 3 especies, A. geoffroyi, A. peruana, y A. carishina. La descripción de Anoura carishina posee varias inconsistencias, y dado que no se realizó una comparación con A. latidens, realizamos una comparación de los caracteres taxonómicos de ambas especies. Para entender la posición de A. carishina en el morfoespacio ocupado por los Anoura grandes realizamos un Análisis de Componentes Principales usando 12 variables cráneo-dentales y 11 variables externas. Complementamos nuestros resultados con 1) un análisis de transformación elíptica de Fourier de la forma del tercer premolar superior (P4) 2) una comparación del área del segundo (P3) y tercer (P4) premolares superiores y 3) una comparación de los ángulos de las hileras dentales maxilares. Encontramos que A. carishina es morfológicamente indistinguible de A. latidens y que existe una amplio superposición en la morfología de A. latidens y A. geoffroyi. Sin embargo, la forma del P4, una cúspide anterobasal no desarrollada en el P3, y caracteres relacionados con una caja craneana menos inflada y un rostro corto son útiles en distinguir A. latidens de A. geoffroyi. Reevaluamos la distribución de Anoura latidens en Colombia, al agregar nuevos registros y corrigiendo registros previamente publicados que se encontraban mal identificados. En general, nuestros resultados sugieren que una taxonomía estable para el grupo debería considerar a A. carishina como un sinónimo junior de A. latidens, que A. latidens es distinguible de A. geoffroyi utilizando medidas cráneo-dentales y resalta la necesidad de estudios genéticos para esclarecer las relaciones filogenéticas entre A. latidens y el complejo de especies A. geoffroyi.
