| 1 | Detection and characterization of diverse alpha-and betacoronaviruses from bats in China显示文摘Bats have been implicated as important reservoir hosts of alpha- and betacoronaviruses. In this study, diverse coronaviruses(CoVs) were detected in 50 of 951(positive rate 5.3%) intestinal specimens of eight bat species collected in four provinces and the Tibet Autonomous Region of China by pan-coronavirus RT-PCR screening. Based on 400-nt RNA-dependent RNA polymerase(Rd RP) sequence analysis, eight belonged to genus Alphacoronavirus and 42 to Betacoronavirus.Among the 50 positive specimens, thirteen gave rise to CoV full-length Rd RP gene amplification for further sequence comparison, of which three divergent sequences(two from a unreported province) were subjected to full genome sequencing. Two complete genomes of betacoronaviruses(JTMC15 and JPDB144) and one nearly-complete genome of alphacoronavirus(JTAC2) were sequenced and their genomic organization predicted. The present study has identified additional numbers of genetically diverse bat-borne coronaviruses with a wide distribution in China. Two new species of bat CoV, identified through sequence comparison and phylogenetic analysis, are proposed. | Lin Xu Fuqiang Zhang Weihong Yang Tinglei Jiang Guanjun Lu Biao He Xingyu Li Tingsong Hu Gang Chen Yun Feng Yuzhen Zhang Quanshui Fan Jiang Feng Hailin Zhang Changchun Tu | 2016 | Virologica Sinica2016，31，1： | 6 |
| 2 | Coexistence of two sympatric and morphologically similar bat species Rhinolophus affinis and Rhinolophus pearsoni显示文摘Ecologists have long focused on the coexistence of sympatric species. Here, we investigated two horseshoe bat species, Rhinolophus a nis and Rhinolophus pearsoni inhabited in the same cave, for their foraging strategies, niche di erentiation, prey selection, and their coexistence status. These two species of horseshoe bats were di erent in the dominant frequency of their echolocation calls, but similar in their morphology. We found evidence for prey selectivity although there was a high degree of overlap in prey categories and sizes. R. a nis and R. pearsoni foraged on 16 and 7 categories insects, respectively, with Pyralidae, Geometridae, Melolonthidae dominating their diets. The degree of trophic niche overlap was 0.69. Pairwise comparisons suggested that there was no obvious di erentiation in prey categories and size. However, high prey availability in the environment (Simpson diversity index = 0.79 and Margalef richness index = 4.12) contributed to their coexistence by dampening the interspeci c competition. Since there are one or more mechanisms facil- itating species coexistence in a community, our results suggest that the spatial niche di erentiation in foraging microhabitats and in for- aging habitats at landscape scale may promote the coexistence of the two bat species. However, additional eld data are needed to con rm this speculation. | Tinglei Jiang Jiang Feng Keping Sun Jing Wang | 2008 | Progress in Natural Science:Materials International2008，18，5： | 5 |
| 3 | Patterns and causes of geographic variation in bat echolocation pulses显示文摘Evolutionary biologists have a long-standing interest in how acoustic signals in animals vary geographically,because divergent ecology and sensory perception play an important role in speciation.Geographic comparisons are valuable in determining the factors that influence divergence of acoustic signals.Bats are social mammals and they depend mainly on echolocation pulses to locate prey,to navigate and to communicate.Mounting evidence shows that geographic variation of bat echolocation pulses is common,with a mean 5-10 kHz differences in peak frequency,and a high level of individual variation may be nested in this geographical variation.However,understanding the geographic variation of echolocation pulses in bats is very difficult,because of differences in sample and statistical analysis techniques as well as the variety of factors shaping the vocal geographic evolution.Geographic differences in echolocation pulses of bats generally lack latitudinal,longitudinal and elevational patterns,and little is known about vocal dialects.Evidence is accumulating to support the fact that geographic variation in echolocation pulses of bats may be caused by genetic drift,cultural drift,ecological selection,sexual selection and social selection.Future studies could relate geographic differences in echolocation pulses to social adaptation,vocal learning strategies and patterns of dispersal.In addition,new statistical techniques and acoustic playback experiments may help to illustrate the causes and consequences of the geographic evolution of echolocation pulse in bats. | Tinglei JIANG Hui WU Jiang FENG | 2015 | Integrative Zoology2015，10，3： | 2 |
| 4 | Bats adjust temporal parameters of echolocation pulses but not those of communication calls in response to traffic noise显示文摘Many studies based on acute short-term noise exposure have demonstrated that animals can adjust their vocalizations in response to ambient noise.However,the effects of chronic noise over a relatively long time scale of multiple days remain largely unclear.Bats rely mainly on acoustic signals for perception of environmental and social communication.Nearly all previous studies on noise-induced vocal adjustments have focused on echolocation pulse sounds.Relatively little is known regarding the effects of noise on social communication calls.Here,we examined the dynamic changes in the temporal parameters of echolocation and communication vocalizations of Vespertilio sinensis when exposed to traffic noise over multiple days.We found that the bats started to modify their echolocation vocalizations on the fourth day of noise exposure,with an increase of 42-91%in the total number of pulse sequences per day.Under noisy conditions,the number of pulses within a pulse sequence decreased by an average of 17.2%,resulting in a significantly slower number of pulses/sequence(P<0.001).However,there was little change in the duration of a pulse sequence.These parameters were not significantly adjusted in most communication vocalizations under the noise condition(all P>0.05),except that the duration decreased and the number of syllables/sequences increased in 1 type of communicative vocalization(P<0.05).This study suggests that bats routinely adjust temporal parameters of echolocation but rarely of communication vocalizations in response to noise condition. | Shengjing SONG Aiqing LIN Tinglei JIANG Xin ZHAO Walter METZNER Jiang FENG | 2019 | Integrative Zoology2019，14，6： | 1 |
| 5 | Vocal performance reflects individual quality in male Great Himalayan leaf-nosed bats(Hipposideros armiger)显示文摘Signals containing parameter trade-offs are likely to be honest indicators of signaler quality because they are difficult to produce.Signals with a trill-rate/bandwidth trade-off have been described for many songbird species,one mouse,and one non-human primate species.However,there were no reports about whether there is a vocal performance trade-off in social calls of bats.This study investigated(1)a possible vocal performance trade-off in territorial calls of male Great Himalayan leaf-nosed bats,Hipposideros armiger,recorded from 9 locations in south China,and(2)the relationships between vocal performance(vocal deviation and consistency)and caller’s quality(body mass)to determine whether vocal performance honestly indicates a caller’s quality.Vocal deviation measures the deviation of a call relative to an extreme call and vocal consistency measures the spectral consistency across a string of syllables.Our results showed a significant negative correlation between syllable repetition rate and frequency bandwidth,suggesting a vocal performance trade-off similar to the one in songbirds.Further,there was a significant negative relationship between body mass and vocal deviation,but no significant correlation between body mass and vocal consistency.This study provides thefirst empirical evidence for a vocal performance trade-off of social calls in bats,and the potential for the level of performance to indicate caller quality. | Congnan SUN Chunmian ZHANG Jeffrey RLUCAS Hao GU Jiang FENG Tinglei JIANG | 2022 | Integrative Zoology2022，17，5： | 0 |
