| henipavirus and tioman virus antibodies in pteropodid bats, madagascar. | specimens were obtained from the 3 malagasy fruit bats, pteropus rufus, eidolon dupreanum, and rousettus madagascariensis. antibodies against nipah, hendra, and tioman viruses were detected by immunoassay in 23 and by serum neutralization tests in 3 of 427 serum samples, which suggests that related viruses have circulated in madagascar. | 2007 | 17370536 |
| parasitism by nycteribiidae and streblidae flies (diptera) of a malagasy fruit bat (pteropodidae): effects of body size and throat gland development on parasite abundance. | we examined the possible effects of host body size and throat gland development on the abundance of blood-feeding nycteribiid and streblid flies parasitizing a malagasy fruit bat, rousettus madagascariensis g. grandidier, 1928. data were collected in the parc national d'ankarana in northern madagascar during four visits: september 2014, 2015 (dry season), and january 2015, 2016 (wet season). two bat fly species were identified, eucampsipoda madagascarensis theodor, 1955 (nycteribiidae) and megas ... | 2017 | 28399201 |
| cone photoreceptor diversity in the retinas of fruit bats (megachiroptera). | older studies have claimed that bats including the megachiroptera (fruit bats or flying foxes) have pure-rod retinas and possess no cone photoreceptors. we have determined the presence and the population densities of spectral cone types in six megachiropteran species belonging to four genera: pteropus rufus, p. niger, p. rodricensis, rousettus madagascariensis, eidolon dupreanum, and epomophorus gambianus. spectral cone types and rods were assessed immunocytochemically with opsin-specific antibo ... | 2007 | 17522478 |
| using stable isotopes to infer the impacts of habitat change on the diets and vertical stratification of frugivorous bats in madagascar. | human-modified habitats are expanding rapidly; many tropical countries have highly fragmented and degraded forests. preserving biodiversity in these areas involves protecting species-like frugivorous bats-that are important to forest regeneration. fruit bats provide critical ecosystem services including seed dispersal, but studies of how their diets are affected by habitat change have often been rather localized. this study used stable isotope analyses (δ15n and δ13c measurement) to examine how ... | 2016 | 27097316 |
| karyotypic evolution in malagasy flying foxes (pteropodidae, chiroptera) and their hipposiderid relatives as determined by comparative chromosome painting. | pteropodidae and hipposideridae are 2 of the 9 chiropteran families that occur on madagascar. despite major advancements in the systematic study of the island's bat fauna, few karyotypic data exist for endemic species. we utilized g- and c-banding in combination with chromosome painting with myotismyotis probes to establish a genome-wide homology among malagasy species belonging to the families pteropodidae (pteropus rufus 2n = 38; rousettus madagascariensis, 2n = 36), hipposideridae (hipposider ... | 2016 | 27256929 |
| hidden diversity of nycteribiidae (diptera) bat flies from the malagasy region and insights on host-parasite interactions. | we present information on nycteribiidae flies parasitizing the bat families pteropodidae, miniopteridae and vespertilionidae from the malagasy region, contributing insight into their diversity and host preference. | 2017 | 29284533 |
| disentangling serology to elucidate henipa- and filovirus transmission in madagascar fruit bats. | bats are reservoirs for emerging human pathogens, including hendra and nipah henipaviruses and ebola and marburg filoviruses. these viruses demonstrate predictable patterns in seasonality and age structure across multiple systems; previous work suggests that they may circulate in madagascar's endemic fruit bats, which are widely consumed as human food. we aimed to (a) document the extent of henipa- and filovirus exposure among malagasy fruit bats, (b) explore seasonality in seroprevalence and se ... | 2019 | 30908623 |
| phylogeny and biogeography of western indian ocean rousettus (chiroptera: pteropodidae). | we examined patterns of genetic variation in rousettus madagascariensis from madagascar and r. obliviosus from the comoros (grande comore, anjouan, and mohéli). genetic distances among individuals on the basis of 1,130 base pairs of the mitochondrial cytochrome b (cytb) locus were estimated from specimens collected from 17 sites on madagascar, 3 sites on grande comore, 3 sites on anjouan, and 2 sites on mohéli. we observed little variation in madagascar and nearshore island samples (maximum 1.1% ... | 2010 | 32287379 |
| rates of hematophagous ectoparasite consumption during grooming by an endemic madagascar fruit bat. | few details are available on the consumption of ectoparasites, specifically bat flies (diptera: nycteribiidae and streblidae), by their chiropteran hosts while grooming. such details are important to document consumption rates of ectoparasites by their bat host provide details on the dynamics of host-parasite interactions. we present data on ectoparasite consumption rates for an endemic malagasy fruit bat (pteropodidae: rousettus madagascariensis) occupying a cave day roost colony in northern ma ... | 2018 | 29859123 |
