Asian Herpetological Research 2019年第3期10卷 158-169页

The Tokay Gecko, Gekko gecko(Linnaeus, 1758) is widely distributed in Asia and there have been concerns regarding locally decreasing populations due to overexploitation for traditional Chinese medicine. Previous studies of the genetic relationships of G. gecko populations included few populations from Thailand. Here we investigated the phylogeographic patterns of G. gecko from different regions in Thailand using mitochondrial cytochrome b sequences. Phylogenetic analyses revealed two lineages: one(Lineage A) comprising populations from Laos, Vietnam, and Thailand;and a second(Lineage B) comprising three genetically distinct groups within Thailand alone. Some Thai populations were found to have both lineages represented within them. Highly significant genetic differentiation(FST) showed geographic population structuring in Lineage B, indicating limited gene flow among groups in Thailand. Although G. gecko has a wide distribution and is well adapted to human habitation, the observed genetic structure could potentially be explained by geographic barriers such as mountain ranges. In Lineage A, our study provided primary phylogeographic evidence for lineage mixture that might be a result of human-mediated transport. Future research should include more extensive sampling across the geographic distribution of G. gecko and a landscape genetics approach could be applied for conservation planning.

Asian Herpetological Research 2015年第3期6卷 189-198页

We provide the first description of the ultrastructure of the spermatozoa of Gekko japonicus, Gekko chinensis and Hemidactylus bowrigii for further understanding of the phylogenetic relationships of gekkonidae. Mature spermatozoa of the three species differ in the occurrence and shape of epinuclear electron-lucent zone, nuclear space, neck cylinder and mitochondria. G. japonicus and G. chinensis have similar spermatozoan ultrastructure while H. bowrigii differs from these two species. In addition, these three species have neck cylinder with mitochondria in neck region and dense bodies arranged in grid with mitochondria in the midpiece, which may be the autapomorphies of the family gekkonidae. Statistical analyses reveal that： total length of the spermatozoa was significantly different between G. japonicus and G. chinensis, as well as between G. japonicus and H. bowrigii（F2,57 = 23.66, P 〈 0.0001）; G. japonicus and H. bowrigii differ in head length（F2,43 = 4.64, P 〈 0.05） and the width of nuclear base（F2,22 = 3.97, P 〈0.05）. In addition, the midpiece length（F2,33 = 23.66, P 〈 0.01） of the spermatozoa was significantly different between H. bowrigii and G. japonicus, and also between H. bowrigii and G. chinensis. Lengths of perforatorium, acrosomal complex and nuclear rostrum and the width of nuclear shoulder are similar in all three species. Our results indicated that the sperm ultrastructure contained intra and intergeneric variabilities which is helpful for better understanding their genetic relationships.

The Caspian bent-toed gecko, Tenuidactylus caspius, belonging to the family gekkonidae, is widely distributed across the northern half of Iran, especially along the southern coastal region of the Caspian Sea. It is regarded as a commensal species throughout its entire distribution. We investigated genetic variation and relationships among different populations of this species in Iran. Fragments of the mitochondrial cyt b（547 bp） and ND4（831 bp） genes were sequenced and analyzed in 64 and 28 specimens, respectively, from 21 geographically distant localities. Cyrtopodion scabrum was used as the outgroup taxon. The data showed no significant genetic variation within the populations of T. caspius in Iran. Nevertheless, populations of Khorasan and Semnan（especially Shahrood） in northeastern Iran showed greater divergence（p-distance = 2.1%） from other Iranian populations. The low genetic variation and homogeneous structure among populations of T. caspius on either side of the Elburz Mountains suggests that this species most likely has achieved its current distribution recently and as a result of anthropogenic activities.

Our study investigated the diet of the southernmost gecko in the world, Homonota darwini. Fifty-three specimens were captured during spring and summer in four locations in Patagonia, Argentina. The stomach contents of the specimens were identified, and we tbund that prey consisted of six main groups： Coleoptera, Hymenoptera, Homoptera and Araneae, and the adults and larvae of moth Lepidoptera. Lepidoptera was the major dietary component. The presence of ants and moths as common prey suggests an ambush feeding strategy. In spring, females consumed more ants than males although no other dietary differences between males and females were evident. We tbund nine geckos with empty stomachs and six parasitized by nematodes. Presence of empty stomachs corroborates previous observations of other nocturnal geckos and non-gecko lizards. Reduced foraging success of nocturnal lizards could be due to difficulty in prey detection due to dim light, reduced or erratic activity of insect prey at night, or shorter activity times of geckos relative to diurnal success. Sex and season were not associated with the incidence of empty stomachs. Principal component analysis showed that four food alternatives correlated with season. The constraint of nocturnality, coupled with low night-time temperatures restricting feeding to only a few hours after sunset, appear to have caused a generality of diet which may limit energy acquisition. We conclude that H. darwini is an arthropod generalist and likely an ambush forager, as are many other nocturnal gekkonids

Generalization of predator recognition:Velvet geckos display anti-predator behaviours in response to chemicals from non-dangerous elapid snakes

引用

Current Zoology 2010年第3期56卷 337-342页

作者： Jonathan K. WEBB Weiguo DU David PIKE Richard SHINE School of Biological Sciences University of Sydney NSW 2006 Australia Department of Environmental Sciences School of Life Sciences Hangzhou Normal College 310036 Hangzhou Zhejiang China

Many prey species detect chemical cues from predators and modify their behaviours in ways that reduce their risk ofpredation. Theory predicts that prey should modify their anti-predator responses according to the degree of threat posed by thepredator. That is, prey should show the strongest responses to chemicals of highly dangerous prey, but should ignore or respondweakly to chemicals from non-dangerous predators. However, if anti-predator behaviours are not costly, and predators are rarelyencountered, prey may exhibit generalised antipredator behaviours to dangerous and non-dangerous predators. In Australia, mostelapid snakes eat lizards, and are therefore potentially dangerous to lizard prey. Recently, we found that the nocturnal velvetgecko Oedura lesueurii responds to chemicals from dangerous and non-dangerous elapid snakes, suggesting that it displays generalisedanti-predator behaviours to chemicals from elapid snakes. To explore the generality of this result, we videotaped the behaviourof velvet geckos in the presence of chemical cues from two small elapid snakes that rarely consume geckos: the nocturnalgolden-crowned snake Cacophis squamulosus and the diurnal marsh snake Hemiaspis signata. We also videotaped geckos in trialsinvolving unscented cards (controls) and cologne-scented cards (pungency controls). In trials involving Cacophis and Hemiaspischemicals, 50% and 63% of geckos spent long time periods (> 3 min) freezing whilst pressed flat against the substrate, *** half the geckos tested exhibited anti-predator behaviours (tail waving, tail vibration, running) in response to Cacophis(67%) or Hemiaspis (63%) chemicals. These behaviours were not observed in control or pungency control trials. Our resultssupport the idea that the velvet gecko displays generalised anti-predator responses to chemical cues from elapid *** responses to predator chemicals may be common in prey species that co-occur with multiple, ecologically similar,

During extensive field work in the Zagros Mountains, western Iran, from October 2013 to November 2014, twenty five localities in different areas of the Kermanshah Province were investigated. Nineteen specimens of Schmidtler＇s dwarf gecko, Microgecko helenae fasciatus, were collected from six localities in western and southeastern regions of the Kermanshah Province. This new collection verifies the presence of M. h. fasciatus in the area after the description of Schmidtler and Schmidtler of the holotype specimen in 1972. All of the collected specimens are consistent with the described specimens in diagnostic characters, as have a uniform dorsal pattern with five distinct dark crossbars and white posterior margins as well as the higher number of dorsal scales between axilla and groin. Detailed morphology of the new specimens is discussed and compared with those of rare previous records. Taxonomy, distribution, and habitat types of this tiny gecko in the western foothills of the Zagros Mountains are also discussed.

Tail Autotomy Does Not Increase Locomotor Costs in the Oriental Leaf-toed Gecko Hemidactylus bowringii

引用

Asian Herpetological Research 2012年第2期3卷 141-146页

作者： Guohua DING Tianbao FU Zongshi ZHOU Xiang JI Jiangsu Key Laboratory for Biodiversity and Biotechnology College of Life Sciences Nanjing Normal University

Tail autotomy is a defense mechanism used by many lizards to evade predators, but it entails costs. We used the oriental leaf-toed gecko Hemidactylus bowringii as a model animal to evaluate locomotor costs of tail autotomy. We removed the tail about 5 mm from the tail base from each of the experimental geckos(adult males) initially having intact tails. Tailless experimental geckos and tailed control geckos were measured for overall speed and sprint speed in both vertical and horizontal directions. Overall speed and sprint speed did not differ between tailless and tailed geckos. The influence of locomotor direction on both overall speed and sprint speed was significant, with horizontal speed being greater than vertical speed. The interaction between tail condition and locomotor direction was not significant in overall speed, but was significant in sprint speed. Tailless geckos had faster vertical sprint speed than the tailed individuals. Of the 130 field-caught adults, 59 had previously lost their tails, with most(about 61%) of them shedding their tails near the tail base. Neither the proportion of geckos with tail autotomy nor the frequency distribution of locations of the tail break differed between the sexes. Our data show that tail loss of H. bowringii occurs frequently in nature. However, tail loss does not incur locomotor costs in this gecko.
