This study highlights the ecology, natural history, and a new distribution record by providing a unique habitat occurrence record in karst ecosystem and describes a tail anomaly of the endemic Mamanwa Bent-toed Gecko Cyrtodactylus mamanwa in the province of Dinagat. The detection of a new population on Unib Island in the southwestern Dinagat extends the previously known distribution of this gekkonid by approximately 100 km south from its known distribution.

We provide the first comprehensive data on the questionable distribution of the genus Pelophylax and the family Ranidae from Pakistan. Based on a literature review and two specimens of the genus from Tasp, Panjgur District in Pakistani Balochistan (USNM 26194–95), stored in the Smithsonian National Museum of Natural History, Washington, DC, USA, we discuss the possible occurrence and affiliation of these frogs in the context of Central Asia. Our comparison shows that the nearest records of Pelophylax in relation to the Tasp specimens are reported from more than 280 km (air-line) away in Iran and Afghanistan, which are currently separated by hot and mostly desert environments. We suggest that possible surviving populations of this genus may still be present in Balochistan (Rakhshan River) or Khyber Pakhtunkhwa (Kabul River) Provinces of Pakistan. This would, however, need further field investigations.
我们提供了关于巴基斯坦蛙科和Pelophylax属可疑分布的第一个全面数据。根据文献综述和保存在美国华盛顿特区史密森尼国家自然历史博物馆的两个来自巴基斯坦俾路支省潘杰古尔区Tasp的该属标本(USNM 26194–95),我们讨论了这些蛙类在中亚的可能发生和隶属关系。我们的比较表明,与Tasp标本有关的Pelophilax的最接近记录是在280多公里外的伊朗和阿富汗报告的,这两个国家目前被炎热的沙漠环境隔开。我们认为,该属可能存活的种群可能仍存在于巴基斯坦的俾路支省(Rakhshan河)或开伯尔-普赫图赫瓦省(Kabul河)。然而,这需要进一步的实地调查。

A second observation on the reproduction of Blythia reticulata was based on three eggs found on a forest path among leaf litter and successfully incubated. Given the limited knowledge on the natural history of the species, including its breeding biology, we provide information on egg measurements (n = 3; length = 25.54 ± 1.05 mm; width = 11.79 ± 0.37 mm; weight = 1.94 ± 0.24 g) and the first data on hatchling biometrics (n = 3; snout-vent length = 106 ± 1.73 mm; tail length = 14 ± 1.00 mm; weight = 1.13 ± 0.09 g) from Mizoram State, northeastern India.
第二次观察是基于在森林小路上的落叶堆中发现的三个成功孵化的卵。鉴于对该物种的自然历史,包括其繁殖生物学的了解有限,我们提供了卵测量的信息(n = 3;长度= 25.54±1.05 mm;宽度= 11.79±0.37 mm;体重= 1.94±0.24 g)和第一次孵化生物特征数据(n = 3;口鼻长度= 106±1.73 mm;尾长= 14±1.00 mm;体重= 1.13±0.09克),产自印度东北部米佐拉姆邦。

This study provides distribution data for 12 species of reptiles in the Southern Bug eco-corridor located within the steppe zone, Mykolaiv Oblast (province), Ukraine. We compiled 935 records from published literature (324), from public databases (68), and from 12 field surveys we made in 2016–2020 (543). All records were mapped on to a grid of 10×10 km, representing the 294 cells of the studied area. We present new distributional data for Podarcis tauricus. For all the other species, our records add new localities that fall within areas where these reptiles were previously reported. Species richness and Shannon’s H’ index show that herpetofauna diversity was higher in the areas along the Southern Bug River. The maximum number of records within a single cell was 118 (for 10 species) in this oblast. Also the high number of identified reptile chorotypes (nine) within the Mykolaiv Oblast revealed that southern Ukraine is an important zoogeographical territory in Europe. These data provide the basis for future biogeographical and ecological studies and conservation priorities.
本研究提供了乌克兰米科莱夫州(省)草原区南虫生态走廊中12种爬行动物的分布数据。我们从已发表的文献(324)、公共数据库(68)和2016-2020年进行的12次实地调查(543)中汇编了935份记录。所有记录都被映射到10×10km的网格上,代表研究区域的294个细胞。我们提出了新的分布数据,牛蒡。对于所有其他物种,我们的记录增加了新的地点,这些地点属于之前报道过这些爬行动物的地区。物种丰富度和Shannon’s H’指数表明,南布格河沿岸地区的爬虫类动物多样性较高。在这个母细胞中,单个细胞内的最大记录数为118个(10个物种)。此外,在米科莱夫州发现的大量爬行动物类群(9个)表明,乌克兰南部是欧洲重要的动物地理区域。这些数据为未来的生物地理学和生态学研究以及保护优先事项提供了基础。

Habitat selection has long been a central theme in ecology and has historically considered both physiological responses and ecological factors affecting species establishment. Investigating habitat selection patterns at different scales can provide important information on the relative roles of the environmental factors influencing the organisms’ abilities to use their surrounding habitat. This work aimed at investigating which environmental factors determine habitat selection by Rhinella icterica tadpoles, and also took the opportunity to investigate how the scale in which tadpoles and environmental data are sampled might influence the habitat selection results. A total of 2.240 tadpoles were counted in the whole sampling area, and while substrate cover and depth were the variables that better explained the abundance of tadpoles at the larger scale (plot level), depth and water turbidity better explained tadpoles’ abundance at the smaller scale (subplot level). The results suggest that avoiding predation by matching the background color is a likely process explaining tadpoles’ occupancy at both scales. Depth is known to influence tadpole habitat use in the tropics, and although its combination with turbidity and substrate cover varied between scales, our study suggests that sampling at different scales might not affect the inferred ecological processes driving habitat selection. This information might also be useful to predict tadpoles’ responses to micro-environmental perturbations and help in guiding the choice of parameters that should be taken into account when analyzing the effects of habitat degradation in Atlantic Forest amphibian populations.
生境选择一直是生态学的中心主题,历史上考虑了影响物种建立的生理反应和生态因素。研究不同尺度的生境选择模式,可以为了解环境因素对生物利用周围生境能力的影响提供重要信息。本研究旨在探讨哪些环境因素决定了黄角鼻虫蝌蚪的栖息地选择,并借此机会研究蝌蚪和环境数据的采样规模如何影响栖息地选择结果。整个采样区共计数蝌蚪2.240只,基质覆盖和深度是更能解释大尺度(样块水平)蝌蚪丰度的变量,而深度和水浊度更能解释小尺度(亚样块水平)蝌蚪丰度的变量。结果表明,通过匹配背景颜色来避免捕食可能是解释蝌蚪在两个尺度上占据的一个过程。众所周知,深度会影响热带地区蝌蚪栖息地的利用,尽管其与浊度和底物覆盖的结合在不同尺度上有所不同,但我们的研究表明,不同尺度的采样可能不会影响推断的驱动栖息地选择的生态过程。这些信息也可能有助于预测蝌蚪对微环境扰动的反应,并有助于指导在分析大西洋森林两栖动物种群栖息地退化影响时应考虑的参数的选择。

We summarised the records of Tarentola mauritanica in Albania. The first record for the country was published in 1989 from Sazan Island; however, it was never confirmed again. Another population was found recently in an urban habitat of Vlorë City near the main city port, probably of human-mediated origin.

Understanding population dynamics is vital in amphibian conservation. To compare demography and movements, we conducted a capture-recapture study over three spring seasons in two populations of Salamandra salamandra in the Vienna Woods. The study sites differ in topography, vegetation, and the type of breeding waters. Population density in a beech forest traversed by a stream was more than twice as high as in an oak-hornbeam forest with temporary pools. Movement distances were on average higher at the latter site whereas home range estimates were similar for both sites. The sexes did not differ significantly in the observed movement patterns at either site. Annual apparent survival was mostly high (~0.85), but the estimate for females from the low-density site was lower (~0.60), indicating a higher rate of emigration or mortality.
了解种群动态对两栖动物保护至关重要。为了比较人口统计学和迁徙,我们在维也纳森林的两个萨拉曼德拉蝾螈种群中进行了一项为期三个春季的捕获-再捕获研究。研究地点的地形、植被和繁殖水域的类型各不相同。一条小溪穿过的山毛榉林的人口密度是有临时水池的橡树角木林的两倍多。后一个地点的移动距离平均较高,而两个地点的家庭范围估计值相似。在两个部位观察到的运动模式中,性别没有显著差异。年表观生存率大多较高(~0.85),但对低密度地区女性的估计较低(~0.60),表明移民率或死亡率较高。

Bite force can be an important aspect of a lizard’s organismal performance, and is likely to be subject to influence by ambient conditions including an individual’s thermal environment. We examined the effects of body temperature (Tb) on initial bite force of rock- and crevice-dwelling individuals of three species of lizards: Abronia graminea (Anguidae), Barisia imbricata (Anguidae), and Xenosaurus fractus (Xenosauridae) from Mexico. In B. imbricata and X. fractus from one site (Xochititan, Puebla) initial bite force was greatest at intermediate Tb. In contrast, X. fractus from a second site (Tlatlauquitepec, Puebla) showed a weak tendency for initial bite force to increase with Tb. Initial bite force in A. graminea was not affected by Tb. Taking our results together, we infer that initial bite force in rock- or crevice-dwelling lizards is often, but not always, related to Tb.
咬合力可能是蜥蜴机体性能的一个重要方面,并且可能受到环境条件的影响,包括个体的热环境。本文研究了温度(Tb)对三种生活在岩石和缝隙中的墨西哥蜥蜴Abronia graminea (Anguidae)、Barisia imbricata (Anguidae)和Xenosaurus fractus (Xenosauridae)个体初始咬力的影响。在同一地点(Xochititan, Puebla)的brbricata和X. fractus中,初始咬合力在中等结核时最大。相比之下,来自第二个地点(Tlatlauquitepec, Puebla)的X. fractus显示出较弱的初始咬合力随Tb增加的趋势。结核杆菌对禾本科单粒稻的初始咬合力没有影响。综合我们的研究结果,我们推断,生活在岩石或裂缝中的蜥蜴的初始咬合力通常与结核有关,但并非总是如此。

Some skin secretions with adhesive properties allow frogs to distract predators and escape; their nature is poorly studied. Here, we report the sticky skin secretion released by the Patagonian frog Eupsophus vertebralis when stressed. This secretion contained ~ 50% proteins spanning 25–250 kDa and required a fast setting time to turn into strong adhesive, which worked well on synthetic and biological materials. Lap-shear assays with Eupsophus glue secretion showed average shear strength of 3.34 MPa, comparable to cyanoacrylate (5.47 MPa). These properties suggest its biotechnological value for practical applications in industrial and medical sectors.
一些具有粘附性的皮肤分泌物使青蛙能够分散捕食者的注意力并逃脱;它们的性质研究得很少。在这里,我们报道了巴塔哥尼亚蛙在受到压力时释放的粘性皮肤分泌物。这种分泌物含有约50%的蛋白质,长度为25-250 kDa,需要快速凝固时间才能变成强粘接剂,在合成材料和生物材料上都很有效。经拉剪实验显示,狗狗胶的平均剪切强度为3.34 MPa,与氰基丙烯酸酯(5.47 MPa)相当。这些特性表明其在工业和医疗部门的实际应用具有生物技术价值。
