The present study was designed to obtain information about life history traits of Lacerta viridis in the Belen population with an altitude of 292 m. In the adult sample (21 males and 15 females), the age ranged from 3 – 10 (X = = 6.97) years for both sexes collectively, 5 – 10 (X = 7.43) years in males, 3 – 8 (X = 6.33) years in females and not differed significantly between sexes. Age at sexual maturity was 2 – 3 years for both sexes. However, a confirmation is required with some sexual characters (e.g., the presence of eggs for female, developed hemipenes for male) for age at sexual maturity in both sexes. The mean body size (SVL) was not significantly different between sexes. There was no correlation between SVL and age for males while there was a positive correlation for females. A male-biased sexual size dimorphism (SSD = 0.07) was observed in the population of L. viridis.

For the first time, a record of Italian Wall Lizard Podarcis siculus (Rafinesque-Schmaltz, 1810) in Krasnodar is noted. The origin of this lizard, presumably, is associated with the importation of large-sized planting material. In addition, for the first time, reproduction of Red-eared Slider, Trachemys scripta elegans (Wied-Neuwied, 1839), in the nature was revealed near Sochi; the data from the moment of oviposition to the emergence of newborns from nesting chambers were collected. The size and color characteristics of T. scripta found in Sochi are described. Active resettlement allowed T. scripta to occupy the entire Imeretinskaya Lowland and the valley of the lower reaches of the Psou River. Monitoring of Podarcis siculus in the environs of Sochi indicates an increase in the range by almost eight times, with a modern habitat area of 200.6 ha. The high population density and a large number of young individuals clearly show the transition of the species from alien to invasive status. A new find in November 2021 of Mediterranean House Gecko, Hemidactylus turcicus (Linnaeus, 1758) indicates the strengthening of this exotic animal in the resort and a slight expansion of the range, about 1 km east of the initial record in Sochi. All of the listed species are, to varying degrees, synanthropic, what also contributes to their active distribution in the region.
首次记录了克拉斯诺达尔的意大利壁蜥蜴Podarcis siculus（Rafinesque Schmaltz，1810）。据推测，这种蜥蜴的起源与进口大型种植材料有关。此外，在索契附近首次发现了红耳滑块在自然界中的复制品Trachemys scripta elegans（Wied Neuwied，1839）；收集了从产卵到新生儿从巢室中出现的数据。介绍了在索契发现的脚本虫的大小和颜色特征。积极的重新安置使T.scripta占领了整个Imeretinskaya低地和普苏河下游的山谷。对索契周边地区冰足虫的监测表明，该范围增加了近8倍，现代栖息地面积为200.6公顷。高种群密度和大量年轻个体清楚地表明了该物种从外来状态向入侵状态的转变。2021年11月，地中海之家壁虎的一项新发现，即半趾壁虎（林奈，1758），表明这种外来动物在度假胜地的实力增强，范围略有扩大，距离索契最初记录以东约1公里。所有列出的物种在不同程度上都是通人的，这也有助于它们在该地区的活跃分布。

The Koyna Toad, Beduka koynayensis, was described some 50 years ago as Bufo koynayensis. Due to taxonomic changes in the generic position now the species is considered under the recently established genus Beduka. Although the terrestrial toad species are morphologically cryptic and difficult to identify them based on morphological characters alone the members of Beduka are exceptions due to clear body colour patterns and habitat specificity. Even though the species is well studied in terms of reproductive biology, call pattern and life history traits there is a lacuna in the understandings of its range of distribution, morphological and genetic variations due to limited field samples available in the museums and the genetic data availability in the GenBank. Based on the fresh collections around the type locality, here we report morphological variations across the different populations within the species. With the 16S rRNA generated in the study discussions are made on the genetic variations across its range of distribution utilizing the unpublished sequences available in the GenBank.

In April and May 2019, we examined seven tadpole samples of two bufonid species Duttaphrynus stomaticus (one site) and Duttaphrynus himalayanus (six sites) taken in the Yamuna River and its tributaries, and the Bhagirathi River at altitudes from 687 m up to 2448 m above sea level; the western part of the Garhwal Himalaya, Uttarakhand, India. Seven categories of larval deformities were recorded: scoliosis, kyphosis, shortened tail, rounded tip of the tail, bifurcated tip of the tail, opercular chamber defect, and edema. The occurrence of malformed tadpoles calculated from a sample size ranged from 3.3 to 13.6%. Water mineralization levels were fluctuated in the limits 37 – 330 mg/dm3, exceeding 100 mg/dm3 in three cases. There was no significant correlation between share of abnormal animals or abnormalities frequency and mineralization as well as with altitude. Mass occurrence of malformed tadpoles was revealed in two places: the Aglad Nadi (= Algar River, 10%, site 1, 687 m) and the town Purola (9.9 – 11.8%, sites 2 and 3, 1339 – 1349 m). Both places were associated with human activity: cattle grazing and residential agrolandscape, respectively. Enlarged rate of anomalies on the town territory may be explained by a synergy between complex of drivers (mineralization, fertilizers and pesticides) that can lead to amplification of general impact on larval morphogenesis. Thus, we reported the first record of mass larval abnormalities in amphibians for the Garhwal in particular and for the Himalaya in general. Formerly published data evidenced that another malformation hotspot of amphibians was situated at the Western Ghats, peninsular India.

Phrynocephalus lizards are well-known for their remarkable tail movements. Possible function of such displays still remains unclear. We present a new approach for studying displays of Phrynocephalus, analyzing them as a sequence of movements. Here, we describe four tail movements of Phrynocephalus guttatus on the basis of observations on the population from the surroundings of Astrakhan, Russia. We found that movement sequences are structured and two main stereotyped patterns for movement sequences are suggested to distinguish depending on function they perform — aggressive or submissive. We also explain differences in preference and structure of movement sequences for lizards of different sex and age groups from the point of their social status.

We studied the helminths parasitizing the individuals of the Turkish smooth newt, Lissotriton schmidtleri (n = 60) and the Balkan crested newt, Triturus ivanbureschi (n = 40) collected from two localities in İzmir, Turkey. Of the 100 newts, 20 (20%) were infected. We detected only one species of parasites, Megalobatrachonema terdentatum (Nematoda: Kathlaniidae), with a prevalence of 0.13% and 0.30% in L. schmidtleri and T. ivanbureschi, respectively. Triturus ivanbureschi represents a new host record for M. terdentatum. Also we present new locality records for both hosts and helminth species.

Recent publications provided some detailed insight into the genus Smithophis, but a paucity of information still exists on the distributional range, conservation, biology, and life history of the members of this genus from the northeast part of India. In the present study, we present new distribution records of the two sympatric Smithophis species, S. atemporalis and S. bicolor from Mizoram State, north-east India. We also provide an updated morphology and descriptions of hemipenes in both the species based on 32 specimens newly collected during the course of our studies (2008 – 2020). The occurrence of a distinct color forms in S. bicolor is documented.

Amphibian migrations are mainly associated with seasonal movements between terrestrial and aquatic (breeding) habitats, but inter-pond migrations during the breeding season present a rarely observed and understudied phenomenon. In 2018 and 2019, a total of 501 individual newts (168 females and 333 males) from two ponds were captured using funnel traps, the ventral side of each newt was photographed and recaptures were identified using the image recognition software Hotspotter ver. 1.0. The distance between ponds was 200 m, with a slight downward slope from pond 1 to pond 2 and terrestrial vegetation consisting of shrubs, grassy patches and trees. All recorded inter-pond migrations were males (three and two individuals in 2018 and 2019, respectively). Between years, ten males were recorded to move between ponds, three of which were identical to individuals that also migrated between ponds within a single season. The observed behavior is discussed in terms of rarity, distance and time of migration.

We resurrect the nominal taxon Boiga ranawanei Samarawickrama, Samarawickrama, Wijesena et Orlov, 2005 as a valid species endemic to Sri Lanka. We uphold the view that B. ranawanei is conspecific with what was previously considered as the Sri Lankan population of ‘B. beddomei’. The revised concept of B. beddomei as a species endemic to the Western Ghats of India and altogether absent from Sri Lanka necessitated the Sri Lankan ‘B. beddomei’ population be conferred with the available nomen B. ranawanei. We also report on further specimens of the two Indian species closely associated with B. ranawanei – B. beddomei that was associated in a nomenclatural sense and B. flaviviridis that is associated in a taxonomic sense. Here, we expand the descriptions of B. beddomei and especially that of B. flaviviridis based on many more additional specimens from several localities across Peninsular India. We again update the key to this group with the inclusion of B. ranawanei. We perform Species Distribution Modelling (SDM) to elaborate on the recorded and simulated distribution range envelopes of the Indian taxa (B. flaviviridis, B. beddomei, B. nuchalis, B. thackerayi) in the B. ceylonesis group. Thus we explain the geographical discontinuity among these taxa to further corroborate our findings on their taxonomic statuses.
我们恢复了Boiga ranawanei Samarawickrama，Samarawicklama，Wijesena et Orlov，2005年的名义分类单元，作为斯里兰卡特有的有效物种。我们坚持这样的观点，即B.ranawanei与之前被认为是“B。贝多梅。B.beddomei是印度西高止山脉特有物种，斯里兰卡完全没有。贝多梅的人口被授予可用的名称B.ranawanei。我们还报告了两个印度物种的进一步标本，这两个物种在命名意义上与ranawanei B.beddomei密切相关，在分类学意义上与黄病毒B.flaviviridis密切相关。在这里，我们根据来自印度半岛几个地方的更多额外标本，扩展了对B.beddomei的描述，尤其是对B.flaviviridis的描述。我们再次更新了这个组的密钥，包括B.ranawanei。我们进行了物种分布建模（SDM），以详细说明B.ceylonsis群中印度分类群（B.flaviviridis、B.beddomei、B.nuchalis、B.thackerayi）的记录和模拟分布范围包络。因此，我们解释了这些分类群之间的地理不连续性，以进一步证实我们对其分类地位的发现。

We uphold the view that B. ranawanei is conspecific with what was previously considered as the Sri Lankan population of ‘B. beddomei’. The revised concept of B. beddomei as a species endemic to the Western Ghats of India and altogether absent from Sri Lanka necessitated the Sri Lankan ‘B. beddomei’ population be conferred with the available nomen B. ranawanei. We also report on further specimens of the two Indian species closely associated with B. ranawanei – B. beddomei that was associated in a nomenclatural sense and B. flaviviridis that is associated in a taxonomic sense. Here, we expand the descriptions of B. beddomei and especially that of B. flaviviridis based on many more additional specimens from several localities across Peninsular India. We again update the key to this group with the inclusion of B. ranawanei. We perform Species Distribution Modelling (SDM) to elaborate on the recorded and simulated distribution range envelopes of the Indian taxa (B. flaviviridis, B. beddomei, B. nuchalis, B. thackerayi) in the B. ceylonesis group. Thus we explain the geographical discontinuity among these taxa to further corroborate our findings on their taxonomic statuses.","PeriodicalId":48693,"journal":{"name":"Russian Journal of Herpetology","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41793312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lankascincus dorsicatenatus is an endemic species of litter-skink distributed throughout the wet zone of Sri Lanka (elevations from 15 to 800 m a.s.l.). The recent resurrection of Lygosoma megalops by the recent description of its neotype designated by Batuwita (2019), presently lost, destabilized the taxonomic status of Lankascincus dorsicatenatus. Amarasinghe et al. (2022) synonymized Lygosoma megalops with Lankascincus fallax, and accepted Lankascincus dorsicatenatus as a valid taxon. Deraniyagala (1953) described Sphenomorphus dorsicatenatus based on a holotype and three paratypes. All the types are lost except one paratype at the National Museum of Sri Lanka, Colombo, Sri Lanka (NMSL), but it is in bad condition. Therefore, with a comparative discussion on the status of ‘Lankascincus megalops‘, here we designate a neotype for Lankascincus dorsicatenatus for clarification of the taxonomic status and stabilize the nomen. A discussion on the distribution and conservation of Lankascincus dorsicatenatus is also provided.
