...Christian C. Voigt; Felix Matt SUMMARY We estimated the effect of nitrogen stress on the nitrogen isotope enrichments in wing membrane and blood of two nectar-feeding bats( Glossophaga soricina and Leptonycteris curasoae ) by offering a nitrogen-poor diet with a high δ 15 N andδ 13 C. Before...

... 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 rates. To test the hypothesis that isotope turnover is higher in nectar-feeding bats, because of their high mass-specific metabolic rates...

... flower bats( Leptonycteris curasoae Martinez and Villa) during hovering flight in normodense and hypodense gas mixtures. Additional experiments examined the effects of supplemental oxygen availability on maximum flight performance. Bats failed to sustain hovering flight at normoxic air densities...
