We estimated the relative contribution of fruits and insects as sources of dietary protein in two species of Neotropical frugivorous bats (Artibeus jamaicensis and Sturnira lilium) using stable carbon and nitrogen isotope analyses. An insectivorous species (Pteronotus parnellii) was also included for comparison. We found constant patterns in stable carbon and nitrogen isotope composition in blood that separated the two species of frugivorous bats from the insectivorous bat. When we used these…

The role of nitrogen from fruit pulp in the nutrition of the frugivorous bat Carollia perspicillata.
TLDR
This analysis suggests that by selecting certain fruit species, frugivorous bats may not need to supplement their diets with insects, and test the hypothesis that nitrogen requirements are met before energy requirements when bats ingest enough fruit to meet their energy requirements.
Comparative analysis of the digestive efficiency and nitrogen and energy requirements of the phyllostomid fruit-bat (Artibeus jamaicensis) and the pteropodid fruit-bat (Rousettus aegyptiacus)
TLDR
All evidence seems to indicate that fruit bats are E maximizers, ingesting more E than required and regulating storage by adjusting metabolic output, and it is suggested that true maintenance E requirements are substantially lower than what was observed.
Trophic relationships among high Arctic seabirds: insights from tissue-dependent stable-isotope models
TLDR
Isotopic estimates suggest greater dependence on lower-trophic-level prey by murres, fulmars, kittiwakes and guillemots than previously established through convenhonal dietary techniques.
Seasonal changes in diets of coastal and riverine mink: the role of spawning Pacific salmon
TLDR
It is indicated that riverine mink depended on salmon (carcasses and fry), with little seasonal or individual var...
Norway rats as predators of burrow-nesting seabirds : Insights from stable isotope analyses
TLDR
Strong correlations between liver and muscle isotope values for both 13 C and 15 N are found, suggesting that dietary preferences within individuals remained relatively constant and have important ramifications for dietary investigations of introduced fauna and their effect on native scabirds on oceanic slands.
Geographic Variation in Carbon Composition of the Pallid Bat, Antrozous pallidus, and its Dietary Implications
TLDR
Although the pallid bat probably visits flowers to eat insects, it is a legitimate pollinator of bat-adapted CAM plants and may represent an early stage in the evolution of nectarivory and frugivory in the Vespertilionidae.
Annual and seasonal changes in diets of martens: evidence from stable isotope analysis
TLDR
Investigation of seasonal and annual changes in diets of martens in response to the changing abundance of small rodents on Chichagof Island, Southeast Alaska concluded that martens, as true generalist predators, switched to alternative prey when their principal food was not readily available on a seasonal or annual basis.
Stable-carbon and nitrogen isotope ratios of songbird feathers grown in two terrestrial biomes : Implications for evaluating trophic relationships and breeding origins
TLDR
Foodweb δ 15 N analysis in each biome indicated that the stable isotope approach could be applied successfully to delineate trophic relationships involving birds and will be a useful tool for investigating the degree of frugivory or nectarivory in birds.
STABLE ISOTOPES IN ANIMAL ECOLOGY: ASSUMPTIONS, CAVEATS, AND A CALL FOR MORE LABORATORY EXPERIMENTS
TLDR
The purpose of this communication is to identify the assumptions on which these inferences are based, to characterize the conditions in which they are not met, and to suggest the laboratory experiments that are needed to validate them.
