Prospects for a comprehensive inventory of global biodiversity would be greatly improved by automating methods species delimitation. The general mixed Yule–coalescent (GMYC) was recently proposed as potential means increasing the rate exploration. We tested this method with simulated data and applied it to group poorly known bats ( Hipposideros ) from Philippines. then used echolocation call characteristics evaluate plausibility boundaries suggested GMYC. In our simulations, GMYC performed...
Karst landscapes are biologically diverse and unique ecosystems that especially important to bats. As in other parts of Southeast Asia, cave roosting bats the Philippines have suffered extensive human disturbance, as a result, may be declining. Here we contributed region-wide effort assess status by surveying well-known caves forest on limestone Bohol Island central Philippines. We also assessed disturbance through physical signs interviews. observed acoustically detected representing total...
Museums hold most of the world's valuable biological specimens and tissues collected, including type material that is often decades or even centuries old. Unfortunately, traditional museum collection storage methods were not designed to preserve nucleic acids held within material, reducing its potential viability value for many genetic applications. High-throughput sequencing technologies associated applications offer new opportunities obtaining sequence data from samples. In particular,...
Differences in body size, echolocation call frequency and location may result diet partitioning among bat species. Comparisons between island populations are one way to evaluate these competing hypotheses. We conducted a species-level analysis of three Rhinolophus Hipposideros species on the Philippine islands Cebu, Bohol Siquijor. identified 655 prey (MOTUs) guano from 77 individual bats. There was high degree overlap species' diets despite differences size frequency. For example, 3...
Parks and other protected areas in tropical forests often include secondary forest, cropland, pasture. Documentation of the impact such anthropogenic disturbance is essential for effective management. We re-sampled bats within Mount Isarog Natural Park (MINP), a area southeastern Luzon, Philippines, seventeen years after survey old- second-growth forest agro-pastoral was conducted 1988. By employing harp traps tunnel trap, addition to mist nets as used earlier study, we aimed document...
High-flying insectivorous bats, as wide-ranging generalist insectivores, are valuable consumers of high-altitude migrating pests rice in Southeast Asia. Here, we documented the behavior relatively low-flying bats over irrigated to elucidate their potential role predators rice-associated pest insects Philippines. Specifically, tested local-scale effects stage, particularly seedling and late vegetative stages, time night on acoustic activity foraging near ground level within three functional...
Abstract Molecular tools have confirmed the presence of morphologically cryptic bat species initially detected by divergent echolocation calls. Here we document two sympatric, genetically distinct populations bats whose calls were similar in peak frequency. They differed only slightly with respect to size, skull and wing morphology, noseleaf shape, but individuals, all identified as Rhinolophus arcuatus , fell into groups exhibiting 3–4% sequence divergence cytochrome b gene. The coexistence...
We used a combination of capture methods—harp traps, tunnel trap, and mist nets—to sample the bat assemblage at two locations (disturbed lowland forest 620 m old-growth montane 1450 m) on Mount Banahaw, Luzon Island, Philippines. placed harp traps nets ridges across trails streams in ravines. The trap was over streams. Over 13 nights, we captured 300 individuals representing 23 species, including possibly undescribed rhinolophid species. Seventy percent all net captures were frugivores...
Rice is the dominant food staple and an important economic resource throughout Asia. Lowland rice production also provides wetland habitats in support of biodiversity that may provide ecosystem services back to agroecosystem. This review summarizes literature on benefits amphibians, birds, bats, rodents context Southeast Asia The evidence these taxonomic groups contribute cultural, regulatory, provisioning smallholder farmers allow for through reduced use chemical inputs into crops. We...
Bats of the genus Kerivoula (Mammalia, Chiroptera) are widespread in Philippines with four reported species, but have been poorly known due to a paucity specimens. We provide first molecular phylogeny for Philippine Kerivoula, which supports existence distinct clades that we treat as species (K. hardwickii, K. papillosa, pellucida, and whiteheadi); these overlap broadly geographically. Each may be recognized on basis cytochrome b sequences external craniodental morphology. Detailed...
The seasonal roost use of Philippine horseshoe bats (Family: Rhinolophidae) is poorly known.Here, we monitored an undisturbed rock crevice comprised four Rhinolophus species on Mount Makiling, Philippines, to document changes in colony size and composition.Evening emergences were videotaped using IR spotlight IR-sensitive camera acoustically recorded ultrasonic detector.Emergence counts ranged from average 7,965 the wet season 177 dry season.Higher emergence season, presence post-lactating...
Abstract The acoustic environment can serve as a niche axis, structuring animal behaviour by providing or obscuring salient information. Meadow katydid choruses occupy the ultrasonic, less studied, realm of this milieu, form dense populations in some habitats and present potential sensory challenge to co‐occurring ultrasonic‐hearing animals. Aerial‐hawking insectivorous bats foraging immediately over vegetation must listen for echoes their prey other cues amidst chorus din. We experimentally...
