“…Sturnira erythromos may use distinct thermal strategies, including daily torpor, to maintain a favorable energetic equation in cool highlands (Soriano et al . ). These responses at the physiological level can be linked with the evolutionary history of the lineage, and if so, the patterns uncovered are deeply rooted in time and tied to the phylogeny of Sturnira and its Andean origin (see Velazco & Patterson ).…”

We evaluated altitudinal segregation in two Sturnira species as a mechanism allowing their coexistence. Tests were devised to discern between interspecific interactions and regional responses to geographic and environmental variables, using extensive capture data from 18 montane rain forest sites. No significant correlation between captures was found. Additionally and according to the hypothesis of historical occupation of highland versus lowland forests, each species has shown specificity in their response to the geographical and environmental variables. Our results indicated that abundance patterns in these bats likely result from the regional distribution of each species rather than local interactions between them, a pattern that may have ancient roots within the group.Abstract in Spanish is available in the online version of this article.

“…There is limited information on the metabolic responses to temperature of Glossophaginae bats from laboratory studies. The existing research has determined lethal temperatures, and/or metabolic curves (Scholander curves) for only seven species, and we do not have values of critical and lethal temperatures for all of them (Arends, Bonaccorso, & Genoud, 1995;Carpenter & Graham, 1967;Cruz-Neto & Abe, 1997;McManus, 1975;McNab, 1969;Soriano, Ruiz, & Arends, 2002). The trait best studied in the laboratory is the lower critical temperature, for which we have data for only six species (Anoura latidens, Choeroniscus godmani, Glossophaga soricina, G. longirostris, Leptonycteris yerbabuenae, and L. curasoae).…”

The thermal niche of a species is one of the main determinants of its ecology and biogeography. In this study, we determined the thermal niche of 23 species of Neotropical nectar‐feeding bats of the subfamily Glossophaginae (Chiroptera, Phyllostomidae). We calculated their thermal niches using temperature data obtained from collection records, by generating a distribution curve of the maximum and minimum temperatures per locality, and using the inflection points of the temperature distributions to estimate the species optimal (STZ) and suboptimal (SRZ) zones of the thermal niche. Additionally, by mapping the values of the STZ and SRZ on a phylogeny of the group, we generated a hypothesis of the evolution of the thermal niches of this clade of nectar‐feeding bats. Finally, we used the characteristics of their thermal niches to predict the responses of these organisms to climate change. We found a large variation in the width and limits of the thermal niches of nectar‐feeding bats. Additionally, while the upper limits of the thermal niches varied little among species, their lower limits differ wildly. The ancestral reconstruction of the thermal niche indicated that this group of Neotropical bats evolved under cooler temperatures. The two clades inside the Glossophaginae differ in the evolution of their thermal niches, with most members of the clade Choeronycterines evolving “colder” thermal niches, while the majority of the species in the clade Glossophagines evolving “warmer” thermal niches. By comparing thermal niches with climate change models, we found that all species could be affected by an increase of 1°C in temperature at the end of this century. This suggests that even nocturnal species could suffer important physiological costs from global warming. Our study highlights the value of scientific collections to obtain ecologically significant physiological data for a large number of species.

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.
