  author={J K Emerson and Alison McCombe Roark},
ABSTRACT Bat guano supports an assemblage of organisms that varies depending on the species of bat producing it. To determine whether these differences in community structure may be due to differences in guano composition, we analyzed guano from frugivorous (Pteropus rodricensis), sanguivorous (Desmodus rotundus), and insectivorous (Tadarida brasiliensis) bats. We found no differences among species in organic matter or lipid of guano. Desmodus guano contained more carbon (C) than Pteropus guano… 

The Life Hidden Inside Caves: Ecological and Economic Importance of Bat Guano

Bats are emblematic hosts of caves. 'ese small flying mammals deserve special attention because their presence has a great economic and ecological impact; they introduce organic matter, the guano, in

Guano exposed: Impact of aerobic conditions on bat fecal microbiota

The results suggest that with careful sample analysis protocols, a more efficient passive collection strategy is feasible; for example, guano could be collected on tarps placed near the roost entrance and greatly reduce the cost of sample collection by allowing more sites or roosts to be surveyed with a fraction of trained personnel, time, and effort investments needed.

Novel Viruses Found in Antricola Ticks Collected in Bat Caves in the Western Amazonia of Brazil

The viral metagenomic investigation of adult ticks showed that single-stranded negative-sense RNA viruses were the dominant group of viruses identified in the investigated ticks, and members of the Nairoviridae family were in clear majority constituting 88% of all viral reads in the data set.

Explaining diversity patterns in dark waters – a study of aquatic caves in Yucatán, Mexico

The trends found in this survey suggest that bats could be important as fertilizers of the caves although mechanistic links that mediate the flux of nutrients need to be confirmed experimentally.


Abstract Caves are important sites of fossil preservation, especially for Quaternary vertebrates. Taphonomic processes operating in caves are not well understood and have never been experimentally

Cave-dwelling bat assemblage of Polillo Island, eastern Philippines

lmost half of Philippine bat fauna (35 species) are known to use caves as roosting sites. Caves in the Philippines are significant livelihood source, from extractive utilization to ecotourism

Correspondence between bats population and terrestrial cave-dwelling arthropods community in Tasikmalaya karst area

Trogloxenes particularly bats play an important role in subterranean habitat. They provide organic material and induce cave microclimate that influence cave-dwelling biota, including arthropods. This

Efficacy of Bat Guano on Growth and Yield of Some Hybrid Sunflower (Helianthus Annus, L.) Cultivars in Sudan

All studied characters of the two cultivars have similarly responded to the application of theTwo types of fertilizers and further studies are recommended to assess the benefits from the use of Bat Guano as a fertilizer.



Trophic structure and natural history of bat guano invertebrate communities, with special reference to Brazilian caves

The trophic structure and natural history of bat guano invertebrate communities in Brazilian caves was compared with information concerning bat guano communities in other caves throughout the world.

Coprophagy in a cave-adapted salamander; the importance of bat guano examined through nutritional and stable isotope analyses

It is predicted that coprophagy may be common in subterranean vertebrates where it is not currently recognized, because many temperate subterranean environments are often energy poor and this limitation is thought to select for increased diet breadth.

Diversity and distribution of spiders associated with bat guano piles in Morrinho cave (Bahia State, Brazil)

Species richness of spiders was positively correlated with the area of the guano piles and silverfish abundance, and negatively correlation with the distance from the cave entrance, while pH of the piles did not show correlation with any other parameters.

The diet of Pteropus voeltzkowi, an endangered fruit bat endemic to Pemba Island, Tanzania

The germination rate of bat-ingested seeds was higher than that for seeds from ripe fruit, and this appeared to be linked to selective ingestion of viable seeds by bats.

Mineral and Nitrogen Concentrations in Feces of Some Neotropical Bats

Concentrations of nitrogen and minerals in individual fecal pellets of Noctilio leporinus directly reflect composition of the fish, crustaceans, beetles, or moths originally consumed. Among

Chitinase in Insectivorous Bats

Chitinase in summer may help to separate parts of insects by breaking down softer connective tissue and in winter it may break down remnants of chitin left over from summer foraging and could even serve as a supplemental source of energy and nutrients.

Folivory in Fruit-Eating Bats, with New Evidence from Artibeus jamaicensis (Chiroptera: Phyllostomidae)

The authors' observations that A. jamaicensis selects and chews leaves high in protein and rejects protein-poor, fibrous pellets, support the hypothesis that these bats extract liquid fractions which contain a reliable source of dietary protein.

Nutritional Values of 14 Fig Species and Bat Feeding Preferences in Panama1

The guild of fruit-eating bats on BCI included ten common species with diets dominated by figs, supporting the idea that although no single species of fig may be sufficient to sustain frugivores, a mix of fig species can provide a complete set of nutrients.
