Low turnover rates of carbon isotopes in tissues of two nectar-feeding bat species.
Stable isotopes of carbon are commonly used to characterize dietary preferences in animals. Because turnover rates of carbon isotopes are related to metabolic rate, we wanted to determine the rates at which carbon isotopes are exchanged in tissues of two species of nectar-feeding bats (Leptonycteris curasoae and Glossophaga soricina), both of which have relatively high mass-specific metabolic r...
متن کاملA new species of nectar-feeding bat, genus Lonchophylla, from the Caatinga of Brazil (Chiroptera, Phyllostomidae)
We describe Lonchophyllainexpectata sp. n. from the Caatinga of Brazil. This new species can be distinguished from all known species of Lonchophylla that occur in Brazil by dental traits, cranial size, and fur colour. Specimens of Lonchophyllainexpectata have been misidentified as Lonchophyllamordax; but Lonchophyllainexpectata is a pale-venter species, similar in external appearance to Lonchop...
متن کاملNectar-feeding bird and bat niches in two worlds: pantropical comparisons of vertebrate pollination systems
Methods An extensive literature review was conducted to compile data bases on the regional and local species richness of nectar-feeding birds and bats, pollinator sizes, morphology, and diets. Coefficients of variation (CVs) were used to quantify the morphospace occupied by the various families of pollinators. The extent to which plants have become evolutionarily specialized for vertebrate poll...
متن کاملAlcohol discrimination and preferences in two species of nectar-feeding primate
Recent reports suggest that dietary ethanol, or alcohol, is a supplemental source of calories for some primates. For example, slow lorises (Nycticebus coucang) consume fermented nectars with a mean alcohol concentration of 0.6% (range: 0.0-3.8%). A similar behaviour is hypothesized for aye-ayes (Daubentonia madagascariensis) based on a single point mutation (A294V) in the gene that encodes alco...
متن کاملA new species of nectar-feeding bat, genus Lonchophylla, from westernColombia and western Ecuador (Mammalia: Chiroptera: Phyllostomidae)
—The twelve recognized species of nectar-feeding bats of the genus Lonchophylla occur in lowand middle-elevation, humid, Neotropical forests. Morphological and morphometrical analyses of specimens formerly lumped with Lonchophylla mordax O. Thomas (1903) support recognition of Lonchophylla concava Goldman (1914) as a separate species and reveal a third species from the western Pacific lowlands ...
