Bat flies: source of supplement nutrients for an endemic Malagasy fruit bat
Among frugivorous vertebrates, the nutritional composition of consumed fruits often needs supplementing by other food types, such as leaves, pollen or invertebrates, to meet dietary requirements. The endemic Malagasy fruit bat, Rousettus madagascariensis (Pteropodidae), actively feeds on their dipteran fly ectoparasites, principally of the family Nycteribiidae and Streblidae, during grooming activities. Since bat flies take blood meals from their hosts, the consumption of these flies by bats might represent a mechanism of recycling and reducing the loss of important nutritional components, such as minerals or proteins and fatty acids. The contribution of these ectoparasites to the diet of R. madagascariensis is 4–10% of the daily protein requirements. This is an important proportion for a species considered to be exclusively frugivorous.
期刊介绍:
Tropical Zoology is an international zoological journal publishing original papers in the field of systematics, biogeography, phylogeny, ecology and conservation of all terrestrial and aquatic animal Phyla from tropical and subtropical areas.
Only papers with new information, high quality and broad interest are considered. Single species description and checklists are not normally accepted. Review papers are welcome. The journal is owned by the Istituto di Ricerca sugli Ecosistemi Terrestri of the Consiglio Nazionale delle Ricerche, Florence, Italy (CNR-IRET) who performs research into the structure and functioning of aquatic and terrestrial ecosystems, focusing in particular on anthropogenic pressure and global change. The knowledge amassed forms the scientific basis for identifying the most appropriate protective and corrective interventions, and provides support for the bodies entrusted with formulating policies for environmental protection and recovery.
