Hermann’s tortoise (Testudo hermanni) is listed as “Near threatened” in the IUCN Red list of endangered species. The importance of protecting the Hermann’s tortoise populations and its habitats have led to the inclusion of the species within CITES Convention (Annex II), Annex A of EU Wildlife Trade Regulation, Annex II of the Bern Convention and Annexes II and IV of the EU Habitats Directive. To assess the distribution and status of the eastern Hermann’s tortoise (Testudo hermanni boettgeri) in Croatia, historical and recent records were gathered and analyzed. The species was recorded in all three biogeographical regions in the country, but it’s native to the Mediterranean and a small part of the Alpine region. With the increase of recent surveys and the use of citizen science platforms, the known range of the species in Croatia was increased by 35.8% and is now encompassing 123 10 × 10 km EEA reference grid cells. Most records (66%) originate from lower elevations (up to 199 m), and the highest was recorded at 570 m. Sparse forests are the most preferred habitats, followed by semi-open habitats, such as grasslands and shrubs. The most serious threat to the species is natural succession due to the increased abandonment of traditional farming and grazing. Other threats include touristic infrastructure and urban development, transportation, illegal collecting, and invasive species. The Area of Occupancy calculated using 2 × 2 km grids resulted in an AOO of 1,372.00 km2, while Extent of Occurrence (EOO) is calculated to be 18,145.07 km2. The current network of National protected areas includes 14% of the species’ AOO while the designated Natura 2000 areas include 29.30% of its AOO. We propose to designate an additional 10 Natura 2000 areas to help with the long-term protection of the species.
赫尔曼龟(Testudo hermanni)在国际自然保护联盟濒危物种红色名录中被列为“近危”。由于保护赫尔曼陆龟种群及其栖息地的重要性,该物种已被纳入《濒危物种公约》(附件二)、《欧盟野生动物贸易条例》附件A、《伯尔尼公约》附件二以及《欧盟栖息地指令》附件二和附件四。为了评估东部赫尔曼龟(Testudo hermanni boettgeri)在克罗地亚的分布和地位,收集并分析了历史和近期的记录。该物种在该国所有三个生物地理区域都有记录,但它原产于地中海和阿尔卑斯山地区的一小部分。随着最近调查的增加和公民科学平台的使用,克罗地亚已知的物种范围增加了35.8%,目前包括123个10×10公里的欧洲经济区参考网格单元。大多数记录(66%)来自低海拔(高达199米),最高记录为570米。稀疏林是最受欢迎的栖息地,其次是半开放栖息地,如草地和灌木。对该物种最严重的威胁是由于越来越多地放弃传统农业和放牧而导致的自然演替。其他威胁包括旅游基础设施和城市发展、交通、非法采集和入侵物种。使用2×2km网格计算的占用面积产生了1372.00 km2的AOO,而发生范围(EOO)计算为18145.07 km2。目前的国家保护区网络包括14%的物种AOO,而指定的Natura 2000区域包括29.30%的AOO。我们建议额外指定10个Natura 2000区域,以帮助对该物种进行长期保护。

The characteristics of microhabitats in streams can drive the distribution of tadpoles. We experimentally examined microhabitat selection of tadpoles of Dryophytes plicatus. We used a series of choice experiments to test if tadpoles had preferences for particular substrate types, substrate colors, and vegetation. Tadpoles of D. plicatus had a strong preference for mud substrates over sand, gravel, and rock substrates and preferred darker substrates over lighter substrates. Dryophytes plicatus tadpoles used the non-vegetated side of an aquarium more than the vegetated side. Our experimental results matched previous field observations in the case of the preference for mud substrates but differed from the field observations for substrate color and vegetation, suggesting that basic underlying preferences may be modified by various factors in nature or by learning or conditioning.
溪流中微小栖息地的特征可以驱动蝌蚪的分布。我们对褶皱苔藓植物蝌蚪的微生境选择进行了实验研究。我们使用了一系列的选择实验来测试蝌蚪是否对特定的基质类型、基质颜色和植被有偏好。褶皱蛙的蝌蚪强烈喜欢泥底质而不是沙子、砾石和岩石底质,喜欢深色底质而非浅色底质。褶皱蝌蚪干苔藓植物更多地使用水族馆的无植被一侧,而不是有植被一侧。在偏爱泥基质的情况下,我们的实验结果与之前的实地观察结果相匹配,但与基质颜色和植被的实地观察不同,这表明基本的潜在偏好可能会受到自然中各种因素或学习或条件的影响。

Pelophylax plancyi (Lataste, 1880), Pelophylax chosenicus (Okada, 1931) and Pelophylax hubeiensis (Fei & Ye, 1982) were described chronologically from East Asia. The three species have similar morphological and molecular characteristics, but the taxonomic relationships amongst them have long been ambiguous. To deal with this taxonomic issue, we examined newly-obtained topotypic specimens of P. plancyi, P. chosenicus and P. hubeiensis for morphological comparison. Furthermore, we investigated the phylogeny of pond frogs in Eurasia by Bayesian Inference and Maximum Likelihood analyses of a fragment consisting of mitochondrial DNA gene 16s and provided a molecular phylogeny of the genus Pelophylax. There were no morphological and molecular differences between P. plancyi and P. chosenicus, but both morphological and molecular differences between P. hubeiensis and P. plancyi. Hence, we conclude that P. chosenicus is a junior synonym of P. plancyi and P. hubeiensis is a separate species from P. plancyi.
从东亚按时间顺序描述了平氏Pelophilax plancyi(Lataste,1880)、乔氏Pelophylax chosenicus(Okada,1931)和湖北氏Pelophalax hubeiensis(Fei&Ye,1982)。这三个物种具有相似的形态和分子特征,但它们之间的分类学关系长期以来一直模糊不清。为了解决这个分类学问题,我们检查了新获得的平盖P.plancyi、乔氏P.chosenicus和湖北P.hubeiensis的拓扑型标本进行形态学比较。此外,我们通过对线粒体DNA基因16s片段的贝叶斯推断和最大似然分析,研究了欧亚大陆池塘蛙的系统发育,并提供了Pelophylax属的分子系统发育。平盖P.plancyi和乔氏P.chosenicus之间没有形态和分子差异,但湖北平盖P.hubeiensis和平盖P.plancyi之间存在形态和分子上的差异。因此,我们得出结论,乔氏P.chosenicus是平盖P.plancyi的初级异名,湖北平盖P.hubeiensis是平盖P.的一个独立物种。

The European leaf toed Gecko, Euleptes europaea, is a strictly nocturnal species endemic to the western Mediterranean and has long been considered a rock-specialist as it is associated with this habitat during its entire daily and life cycle. In this study, we report observations of arboreal behaviour in E. europaea, collected during field research over a 40-year period from across the entire species range. We provide a review of the available information on this topic that contributes to a refined view of the habitat uses and arboreal abilities of this species. Arboreal behaviour in E. europaea was observed throughout the year, across different macrohabitats, on a wide variety of tree, shrub, and bush species, on various parts of the plant (trunk, branches, fronds, twigs, leaves), and at different height from the ground. Remarkably, E. europaea shows an extraordinarily agile arboreal locomotion associated with striking morphological adaptations to an arboreal lifestyle, namely a prehensile tail bearing a terminal adhesive pad that supplements grasping force, an equilibrium asset, and scansor adhesion both in static condition and during escape. We conclude that E. europaea is a climbing gecko (opposed to ground dwelling), occupying both rocky and arboreal microhabitats. While the evolutionary origin and ecological drivers of the arboreal behaviour of E. europaea remains to be fully investigated, this realization has important implications for designing fieldwork research and management strategies for conservation.
欧洲叶趾壁虎(Euleptes europaea)是地中海西部特有的夜行动物,长期以来一直被认为是岩石专家,因为它在整个日常生活和生命周期中都与这个栖息地有关。在这项研究中,我们报告了在整个物种范围内40年的野外研究中收集的欧洲e.o europaea树栖行为的观察结果。我们对这一主题的现有信息进行了回顾,有助于对该物种的栖息地利用和树栖能力有一个更好的认识。在不同的大生境中,在各种各样的乔木、灌木和灌木物种上,在植物的不同部位(树干、树枝、叶子、小枝、叶子),以及在离地面不同的高度上,全年都观察到欧洲e.o europaea的树栖行为。值得注意的是,E. europaea表现出一种非常敏捷的树栖运动,这与对树栖生活方式的惊人形态适应有关,即一条可抓握的尾巴,其末端有一个粘附垫,可以在静态状态和逃逸状态下补充抓握力、平衡资产和扫描粘附力。我们认为欧洲壁虎是一种攀爬壁虎(与地面壁虎相反),既占据岩石微生境,也占据树栖微生境。虽然尚不清楚欧洲东洋树栖行为的进化起源和生态驱动因素,但这一认识对设计野外调查和保护管理策略具有重要意义。

We describe the advertisement call of the Nanling horned frog, Boulenophrys nanlingensis for the first time, based on recordings obtained from four individuals. One of these individuals, which was identified using its dorsum pattern, was recorded twice after nine months. Distinct shifts in the temporal parameters and call rate were observed from calls of the re-captured individual, which was suspected to be related to temperature and social context. However, due to the limited sample size, further research is needed to confirm these findings. We highlight the potential of mark-recapture method using dorsum pattern for studying and monitoring the Nanling horned frog and other megophyinid frogs.
根据四个个体的记录,我们首次描述了南岭角蛙Boulenophrys nanlingensis的广告叫声。其中一个个体是通过其背模式识别的,在九个月后被记录了两次。从重新捕获的个体的呼叫中观察到时间参数和呼叫率的明显变化,这被怀疑与温度和社会背景有关。然而,由于样本量有限,还需要进一步的研究来证实这些发现。我们强调了利用背模式的标记再捕获方法在研究和监测南岭角蛙和其他甲壳类蛙方面的潜力。

Atlantolacerta andreanskyi (Werner, 1929) is an endemic lizard from the High Atlas Mountains region of Morocco. A previous molecular assessment of this species using mitochondrial and nuclear DNA markers uncovered extensive genetic diversity with seven lineages indicative of a species complex. A morphological assessment of six of these lineages did not establish simple diagnostic features, and proposed these should be considered as a cryptic species, while highlighting the need for greater sampling across the range. In this study, we sampled 8 individuals from 5 previously unsampled localities and carried out genetic analyses to compare these populations to the known variation. Phylogenetic reconstruction based on mitochondrial DNA markers (12S rRNA and ND4) corroborates the previously described lineages and identified a new one. Interestingly, the two samples that account for this newly identified lineage have been collected from distinct localities – M’goun and Toumliline – that form a sister taxon to the population of Jbel Azourki.
anantolacerta andreanskyi (Werner, 1929)是摩洛哥高阿特拉斯山脉地区的一种地方性蜥蜴。先前使用线粒体和核DNA标记对该物种进行的分子评估揭示了广泛的遗传多样性,有7个谱系表明一个物种复合体。对其中6个谱系的形态学评估并没有建立简单的诊断特征,并提出这些谱系应被视为隐种,同时强调需要在整个范围内进行更大的采样。在这项研究中,我们从5个以前未采样的地点取样了8个个体,并进行了遗传分析,将这些种群与已知变异进行了比较。基于线粒体DNA标记(12S rRNA和ND4)的系统发育重建证实了先前描述的谱系,并鉴定了一个新的谱系。有趣的是,解释这一新发现谱系的两个样本是从不同的地方收集的——M 'goun和Toumliline——它们形成了Jbel Azourki种群的姐妹分类群。

We present new natural history data on abundance and movements (daily and seasonal) during the pre-breeding (March-June) and breeding-post-breeding season (July-September) of two poorly studied frog species of the Himalayas, Nanorana vicina and Allopaa hazarensis. We estimated 185 Murree Hills Frogs and 90 Hazara Frogs within the study area (0.79 ha). The daily and seasonal movement data showed that the two species moved either between neighboring ponds or remained in an array of smaller ponds (within an area of 120 m2) along the stream bank. About 75% of movements were < 29.5 m in N. vicina and < 50.87 m in A. hazarensis during pre-breeding season while < 41.5 m in N. vicina and < 81 m in A. hazarensis during breeding-post-breeding season. We suggest inclusion of amphibian habitat requirements and ensuring stream connectivity in urban planning and development projects in the area to prevent the local extinction of the endemic species. In the future, more robust and long-term studies, encompassing more streams situated within a wider area, would help clarify dispersal, colonization, metapopulation structure, and dynamics of these endemic frogs of the forested montane streams in the Himalayan Foothills.
我们提供了关于喜马拉雅山脉两种研究不足的蛙类Nanorana vicina和Allopaa hazarensis在繁殖前(3-6月)和繁殖后(7-9月)的丰度和运动(每日和季节性)的新的自然历史数据。我们估计研究区域(0.79公顷)内有185只Murree Hills蛙和90只Hazara蛙。每日和季节移动数据显示,这两个物种要么在相邻的池塘之间移动,要么留在河岸的一排较小的池塘中(面积为120平方米)。在繁殖前季节,约75%的移动在N.vicina中<29.5米,在A.hazarensis中<50.87米,而在繁殖后季节,在N.vicino中<41.5米,在A.hazarensi斯中<81米。我们建议在该地区的城市规划和发展项目中纳入两栖动物栖息地要求,并确保溪流连通性,以防止当地特有物种的灭绝。未来,更有力和长期的研究,包括位于更大区域内的更多溪流,将有助于澄清喜马拉雅山麓森林山地溪流中这些特有蛙类的扩散、定殖、集合种群结构和动态。

We describe a new species of Eleutherodactylus (subgenus Syrrhophus) from Guerrero, Mexico, based on morphological and molecular data, as well as advertisement call analysis. Eleutherodactylus franzisp. nov. has unique features including widely expanded fingertips, indistinct, but visible lumbo-inguinal glands, an immaculate white venter and dark reticulations on a cream dorsal background colouration. The new species belongs to the Eleutherodactylus nitidus species group. Eleutherodactylus franzisp. nov. is micro-endemic, restricted to a small range in karstic hillsides on the southern extreme of the Mexican Transverse Ranges. We discuss conservation needs of this species, which we provisionally classify as Critically Endangered.
根据形态学和分子特征以及广告叫声分析,描述了一种来自墨西哥Guerrero的Eleutherodactylus (Syrrhophus亚属)新种。Eleutherodactylus franzisp。11月有独特的特征,包括广泛扩大的指尖,不清楚,但可见的腰腹股沟腺,一个完美无瑕的白色腹和深色网状在奶油背背景色。该新种属于伊拟龙属(Eleutherodactylus nitidus)种群。Eleutherodactylus franzisp。11月是微地方性的,局限于墨西哥横向山脉南端喀斯特山坡的一个小范围。我们讨论了这个物种的保护需求,我们暂时将其列为极度濒危物种。

The golden Alpine salamander Salamandra atra aurorae Trevisan, 1982 is an endemic subspecies found in Sette Comuni and Vezzena plateau in Veneto, Italy. We describe an aggressive interaction between two males which fought for four minutes, trying to go on top of each other and rubbing their chin on the antagonist’s head. This is the first documented case of aggressive behaviour in Salamandra atra aurorae.

Microhabitat sharing for basking between squamate species in Poland 波兰鳞片物种之间共享晒太阳的微栖息地
IF 0.9 4区 生物学 Q3 ZOOLOGY Pub Date : 2023-03-27 DOI: 10.3897/herpetozoa.36.e94064

Aggregations (e.g. group basking) by snakes are usually limited to specific life cycle phases (e.g. mating) or are a consequence of drastic environmental changes (e.g. habitat destruction), high prey densities or highly limited resources within an environment (e.g. basking sites, wintering dens). Here, we report intra- and interspecific observations of four reptile species (primarily Natrix natrix and Vipera berus) sharing basking sites at the confluence of the rivers Dunajec and Poprad near the town of Stary Sącz in southern Poland. From a total of 84 records in the field between 2020–2022, there were 11 interactions from 24 July 2020 to 1 May 2022. Previous studies have indicated direct competition or interference in many species, which we did not observe. There is a noticeable lack of such observations of microhabitat sharing for basking between squamate species in scientific literature. Hence, the accumulation of such observations has the potential to reveal new insights into the behaviour and ecology of N. natrix and V. berus.
蛇的聚集(例如集体晒太阳)通常局限于特定的生命周期阶段(例如交配),或者是环境剧烈变化(例如栖息地破坏)、猎物密度高或环境中资源高度有限(例如晒太阳的地点、越冬窝点)的结果。在这里,我们报告了四种爬行动物(主要是Natrix Natrix和Vipera berus)在波兰南部Stary Sãcz镇附近的Dunajec河和Poprad河交汇处共享日光浴场所的种内和种间观察结果。在2020年至2022年期间,该领域共有84项记录,从2020年7月24日到2022年5月1日,共有11次互动。先前的研究表明,许多物种存在直接竞争或干扰,但我们没有观察到。在科学文献中,明显缺乏对鳞片物种之间共享微栖息地晒太阳的观察。因此,这些观察结果的积累有可能揭示对N.natrix和V.berus的行为和生态学的新见解。
