ABSTRACT There are notable examples of repeated evolution of ecomorphs within groups of closely related species, these are typically viewed as remarkable cases of natural selection. In most cases, directional selection for certain phenotypic traits under specific (and differing) environmental conditions is implicated. Differing ecomorphological forms for closely related species (or for populations within a species) have been documented for several lineages of South African dwarf chameleons (Bradypodion), although this pattern is not ubiquitous across the genus. Within one species, Bradypodion pumilum, two ecomorphs have been observed, these differ in terms of morphology, performance, ecology and habitat, yet genetic differences (mtDNA) were not apparent, with shared haplotypes across the ecomorphs. We investigated whether more sensitive genetic markers (eight microsatellite loci) would show population level structure between ecomorphs, which could indicate lack of gene flow across the ecological (habitat) boundary. Our results suggest that the two ecomorphs are distinct at a population level, implying that gene flow is absent or reduced and that the two ecomorphs are on separate evolutionary trajectories. Given that mtDNA could not detect population structure, we infer that the ecological boundary between ecomorphs is relatively recent in evolutionary history. The two ecomorphs are distinctive in terms of their morphology, ecology, habitat and functional traits, these differences are likely driven and maintained by reproductive isolation across the habitat boundary.
摘要在亲缘关系密切的物种群中,有一些显著的生态形态重复进化的例子,这些例子通常被视为自然选择的显著案例。在大多数情况下,涉及在特定(和不同)环境条件下对某些表型性状的定向选择。南非矮变色龙(Bradypodion)的几个谱系记录了亲缘关系密切的物种(或一个物种内的种群)的不同生态形态,尽管这种模式在整个属中并不普遍。在一个物种Bradypodion pumilum中,已经观察到两种生态形态,它们在形态、性能、生态和栖息地方面有所不同,但遗传差异(mtDNA)并不明显,在不同的生态形态中存在共享的单倍型。我们研究了更敏感的遗传标记(8个微卫星基因座)是否会显示生态形态之间的种群水平结构,这可能表明缺乏跨生态(栖息地)边界的基因流动。我们的研究结果表明,这两种电子形态在种群水平上是不同的,这意味着基因流动不存在或减少,并且这两种生态形态处于不同的进化轨迹上。鉴于mtDNA无法检测种群结构,我们推断生态形态之间的生态边界在进化史上相对较新。这两种生态形态在形态、生态、栖息地和功能特征方面是不同的,这些差异可能是由跨越栖息地边界的繁殖隔离所驱动和维持的。

ABSTRACT We studied the composition and seasonal changes in diet and prey selection in the wall lizard Podarcis vaucheri of the Djurdjura Mountains throughout its activity period, from April to October 2014. The analysis of 238 faecal pellets revealed 1 206 prey items distributed in 19 prey categories. The most important prey categories were: Formicidae, Coleoptera, Aranea, Homoptera, and Orthoptera. Significant seasonal variation in the taxonomic composition of the diet and prey availability was found. A significant difference in diet composition was observed between males and females in spring. This lizard species displayed a more diverse dietary spectrum during this period, followed by a slight decrease in summer. However, a severe decrease in the food niche breadth was observed in autumn, resulting in a high consumption of ants. A comparison of diet composition and prey availability showed that lizards exhibited a clear selection of certain prey types, in contrast to what is often suggested for lacertid lizards.
摘要研究了2014年4 - 10月Djurdjura山沃切利壁蜥(Podarcis vaucheri)活动期间的组成、食性和猎物选择的季节变化。对238粒粪球进行分析,发现猎物1 206个,分布在19个猎物类别中。最主要的猎物类别为蚁科、鞘翅目、蜘蛛目、同翅目和直翅目。在食性和猎物可得性的分类组成上发现了显著的季节变化。春季雄性和雌性的日粮组成有显著差异。这种蜥蜴在这一时期表现出更多样化的饮食谱,随后在夏季略有减少。然而,秋季食物生态位宽度明显减小,导致蚂蚁的大量消耗。一项对饮食组成和猎物可获得性的比较表明,蜥蜴对某些猎物类型有明确的选择,这与通常认为的蛇蜥不同。

ABSTRACT The Endangered Pickersgill’s Reed Frog (Hyperolius pickersgilli) is endemic to South Africa and restricted to the KwaZulu-Natal (KZN) coast. The natural habitat of H. pickersgilli is limited to fragmented patches of coastal reed-bed wetland, the majority of which continues to undergo transformation and degradation caused by urbanisation, agriculture, mining and forestry. These changes have resulted in the steady reduction of suitable, quality habitat and severe fragmentation. In the current study we employed mitochondrial DNA and species-specific microsatellites markers (developed in the current study) to investigate the genetic structure and diversity of H. pickersgilli. Genetic markers revealed moderate to high levels of genetic diversity throughout the remnant groups and absence of specific phylogeographic structure among individuals sampled across twelve localities throughout the range of the species. Results from the current study indicate that gene flow between H. pickersgilli individuals is not restricted, whereby neighbouring groups may interact with each other through continued migration, thereby facilitating possible range expansion should habitat be available. However, the need for continued conservation of the H. pickersgilli population through the protection and management of its natural habitats should remain a top priority in order to conserve representative levels of genetic diversity.
摘要:濒临灭绝的皮克斯吉尔苇蛙(Hyperolius pickersgilli)是南非的特有种,仅限于夸祖鲁-纳塔尔(KZN)海岸。H.pickersgilli的自然栖息地仅限于零散的沿海芦苇床湿地,其中大多数湿地仍在经历城市化、农业、采矿和林业造成的转型和退化。这些变化导致了适宜的优质栖息地的不断减少和严重的破碎化。在当前的研究中,我们使用线粒体DNA和物种特异性微卫星标记(在当前研究中开发)来研究H.pickersgilli的遗传结构和多样性。遗传标记显示,在整个物种范围内的12个地点取样的个体中,整个残余群体的遗传多样性处于中等至高水平,并且缺乏特定的系统地理结构。目前的研究结果表明,H.pickersgilli个体之间的基因流动没有受到限制,因此相邻群体可以通过持续迁徙相互作用,从而在有栖息地的情况下促进可能的范围扩大。然而,需要通过保护和管理其自然栖息地来继续保护H.pickersgilli种群,这仍然是一个首要任务,以保护具有代表性的遗传多样性水平。

ABSTRACT West Africa is a region characterised by high species diversity and endemism, making it an ideal region to study the evolution of genetic and phenotypic differentiation. Species in this region often vary in morphology and genetics; however, the specific drivers of these differences have not been clearly identified. Focusing on populations in Ghana, we tested for correlations between geography, genetic diversity, morphology and ecology in the West African rainbow lizard (Agama picticauda). Genetic data were collected from 102 specimens using double-digest restriction site-associated DNA sequencing (ddRADseq) and the final data matrix included 5 976 loci and 20 624 single nucleotide polymorphisms (SNPs). Morphological data were collected from 42 specimens and included 6 meristic and 4 mensural characters. Ecological data were obtained from the WorldClim database to a resolution of 30 arcseconds. Population structure analyses supported up to five distinct populations of A. picticauda in Ghana. Discriminant function analyses were used to classify samples using the morphological data and ecological data. Ecology showed the strongest correlation with population genetic structure, whereas morphological data were only able to weakly differentiate three populations. We discuss the factors that might be responsible for correlations between phenotypes and genotypes in the context of A. picticauda natural history.
摘要西非是一个物种多样性和地方性较高的地区,是研究遗传和表型分化进化的理想地区。该地区的物种在形态和遗传学上往往各不相同;然而,这些差异的具体驱动因素尚未明确。以加纳的种群为重点,我们测试了西非彩虹蜥蜴(Agama picticauda)的地理、遗传多样性、形态和生态之间的相关性。使用双消化限制性位点相关DNA测序(ddRADseq)从102个样本中收集遗传数据,最终数据矩阵包括5 976个基因座和20 624个单核苷酸多态性(SNPs)。从42个标本中收集了形态学数据,包括6个分生组织和4个月经特征。生态数据是从WorldClim数据库中获得的,分辨率为30角秒。人口结构分析支持了加纳多达五个不同的画眉草种群。判别函数分析用于利用形态数据和生态数据对样本进行分类。生态学与种群遗传结构的相关性最强,而形态学数据只能微弱地区分三个种群。我们在A.picticauda自然史的背景下讨论了表型和基因型之间相关性的可能因素。

ABSTRACT The anatomy of African lacertid lizards (Lacertidae: Eremiadini) is poorly known, which has hindered a better understanding of their evolutionary relationships. This applies especially to the East African clade, which includes the genera Nucras, Latastia, Philochortus, Pseuderemias and Heliobolus. We present a detailed description of the skull osteology of the genus Heliobolus using X-ray microcomputed tomography and compare its morphology to the above lacertid taxa. Because the genus Heliobolus includes species of doubtful validity and affinities (Heliobolus neumanni and Heliobolus nitidus), we also present a detailed intrageneric comparison and construct a morphological character matrix that we analyse against a phylogenetic backbone derived from previous molecular studies. Heliobolus lugubris and Heliobolus spekii can be well characterised as a monophyletic group on the basis of a short postorbital and a continuously broad posterior margin of the parietal, differing from H. nitidus and other members of the East African clade in an overall low degree of ossification and reduced ventral extension of the frontal bone. Our preliminary phylogenetic analysis suggests that the genus Heliobolus is currently polyphyletic. We propose that the name H. neumanni be officially retracted, because specimens assigned to this species show very different morphologies relative to each other and are placed in different parts of the tree in our analysis. Also, the type specimen is lost and no specimens were collected from the type locality. H. nitidus shows a signal towards the genus Latastia. A definitive, new generic assignment of H. nitidus must await further investigations based on molecular data.
摘要非洲撕裂蜥蜴(撕裂蜥蜴科:Eremiadini)的解剖结构鲜为人知,这阻碍了人们更好地了解它们的进化关系。这尤其适用于东非分支,包括Nucras属、Latastia属、Philochortus属、Pseuderemias属和Heliobolus属。我们使用X射线微计算机断层扫描对Heliobolus属的头骨骨学进行了详细描述,并将其形态与上述撕裂分类群进行了比较。由于Heliobolus属包括有效性和亲缘关系可疑的物种(Heliobolusneumanni和Heliobolussnitidus),我们还进行了详细的属内比较,并构建了一个形态特征矩阵,我们根据先前分子研究得出的系统发育主干进行分析。lugubris和spekii Heliobolus可以很好地描述为一个单系群,其特征是眶后较短,顶骨后缘持续较宽,与H.nitidus和东非分支的其他成员不同,其骨化程度总体较低,额骨的腹侧延伸减少。我们的初步系统发育分析表明,Heliobolus属目前是多系的。我们建议正式收回H.neumanni这个名字,因为在我们的分析中,分配给这个物种的标本显示出彼此非常不同的形态,并且被放置在树的不同部分。此外,模式标本丢失,没有从模式地区采集到任何标本。H.nitidus显示了一个朝向Latastia属的信号。根据分子数据,必须等待进一步的研究,才能确定新的H.nitidus属。

ABSTRACT Leaf-litter skinks of the genus Panaspis are currently represented in the oceanic islands of the Gulf of Guinea by two species, Panaspis africana and P. annobonensis. Here we describe a third species, Panaspis thomensis sp. nov., endemic to São Tomé Island. Data from previous studies and a new phylogenetic analysis using the mitochondrial 16S gene shows that the new species is genetically divergent and reciprocally monophyletic with respect to P. africana. Morphological data (scalation and morphometry) identify consistent, yet subtle, phenotypic differences between the two island populations. We also confirm that P. annobonensis represents a valid species, sister to the species pair P. africana + P. thomensis sp. nov., based on both molecular and morphological evidence. This description raises the number of known Panaspis species in the Gulf of Guinea oceanic islands to three, with consequences for the interpretation of local endemicity.

摘要Panaspis属的落叶皮蛙目前在几内亚湾的海洋岛屿上有两个物种,非洲Panaspis和安诺博南P.annobonensis。在这里,我们描述了第三个物种,Panaspis thomensis sp.nov.,圣多美岛特有种。来自先前研究的数据和使用线粒体16S基因进行的新的系统发育分析表明,该新物种与非洲P.africana在遗传上是不同的,并且是相互单系的。形态学数据(分级和形态计量学)确定了两个岛屿种群之间一致但微妙的表型差异。我们还证实,P.annobonensis代表了一个有效的物种,是物种对P.africana的姐妹 + P.thomensis sp.nov.,基于分子和形态学证据。这一描述将几内亚湾海岛上已知的Panaspis物种数量提高到了三种,这对解释当地特有性产生了影响。ZooBank——Panaspis thomensis:lsid:ZooBank.org:act:A1E69D28-CF4C-4070-BBCC-91E39C21DBA6

ABSTRACT Pachydactylus is the most species-rich reptile genus in southern Africa. Most species are habitat specialists adapted to hyper-arid conditions of the Namibian and north-western South African xeric regions. Although a fair number of phylogenetic studies and taxonomic revisions have been published, some species still remain rather enigmatic. In the ten years since the taxonomic revision of the weberi group, some of the species have not been recorded and our knowledge on their distribution, phylogenetic affinities, or intraspecific variability is limited or non-existent. Pachydactylus goodi is one such species. In this study, we report a newly discovered population of P. goodi in the Richtersveld National Park, South Africa, which considerably extends the known range of the species. In addition, the results of our phylogenetic analyses indicate that P. goodi is paraphyletic with respect to P. atorquatus. Although there is a striking colour polymorphism observed between these two species, the level of genetic differentiation within the goodi-atorquatus clade is comparable with intraspecific variability observed in other Pachydactylus species. As a result of these findings, which are further supported by morphological similarity of the two species, we conclude that they represent a single species and synonymise P. goodi with P. atorquatus.
厚趾龙是非洲南部种类最丰富的爬行动物属。大多数物种是适应纳米比亚和南非西北部干旱地区极度干旱条件的栖息地专家。尽管已经发表了相当数量的系统发育研究和分类修订,但一些物种仍然相当神秘。近十年来,有些物种尚未被记录,我们对它们的分布、系统发育亲缘关系和种内变异的认识有限或不存在。厚趾龙就是这样一个物种。在这项研究中,我们报告了在南非Richtersveld国家公园新发现的P. goodi种群,这大大扩展了该物种的已知范围。此外,我们的系统发育分析结果表明,与阿托尔库塔相比,古迪假单胞菌是副葡萄球菌。尽管在这两个物种之间观察到显著的颜色多态性,但在good -atorquatus进化枝内的遗传分化水平与在其他厚趾足物种中观察到的种内变异相当。由于这些发现,进一步支持了两种形态的相似性,我们得出结论,它们代表一个单一的物种,并将P. goodi与P. atorquatus同义。

ABSTRACT Since 1957, all padlopers were considered Homopus, which was an anomaly, because only two species have four claws on the front and hind limbs. The revival of the genus Chersobius for the five-toed species (signatus, boulengeri and solus) now limits Homopus to the four-toed species (areolatus and femoralis). Molecular data indicate that Homopus is paraphyletic with two well-supported clades: the four-toed Homopus in one clade and the five-toed Chersobius together with Chersina angulata in a second clade. There are numerous distinct morphological and ecological differences between the genera. All Chersobius species have a single, large inguinal scute, whereas the number is variable in Homopus. The midline pectoral scute of Chersobius is consistently longer, and the nuchal scute shorter, than in Homopus. The fourth to fifth vertebral suture is narrow in Homopus and broad in Chersobius. Forelimb scales also differ with 3–4 large rows and 5–6 smaller rows, respectively, in Homopus and Chersobius. Chersobius males have a plastral concavity and Homopus males not. Two Chersobius species (C. signatus and C. boulengeri) are distinguishable from Homopus by having 12 or more marginal scutes, whereas Homopus species have 11 or fewer. The glans penes are respectively V-shaped and heart-shaped in Homopus and Chersobius. Ecological differences include that Chersobius species are rupicolous and inhabit arid regions, whereas Homopus species inhabit more mesic habitats. Homopus females produce multi-egg clutches and tend to be bigger compared to single-egg clutching Chersobius females. Females of all species are larger than conspecific males, and all males have larger shell openings than females have. ZooBank—urn:lsid:zoobank.org:pub: 18229454-6662-46F3-8B15-836BF2AC38EB
自1957年以来,所有的padlopers都被认为是Homopus,这是一个异常,因为只有两个物种的前肢和后肢上有四个爪子。五趾物种(signatus, boulengeri和solus)的Chersobius属的复兴现在将同趾物种限制在四趾物种(areolatus和femoralis)。分子数据表明,同形人属具有两个分支:一个分支为四趾同形人属,另一个分支为五趾切氏同形人属和角切氏同形人属。这两个属之间有许多明显的形态和生态差异。所有的Chersobius物种都有一个单一的,大的腹股沟鳞片,而在Homopus中,数量是可变的。与同人猿相比,Chersobius的胸甲中线一贯较长,颈甲较短。第四至第五椎骨缝线在同足猴中狭窄,在切索比猴中宽阔。同人目和切氏目的前肢鳞片也不同,分别有3-4大排和5-6小排。切索比乌斯的雄性有子宫凹陷,而同人猿的雄性则没有。两个Chersobius种(C. signatus和C. boulengeri)与Homopus有12个或更多的边缘鳞片,而Homopus种有11个或更少的边缘鳞片。同人目和切索比目的龟头分别为v形和心形。生态上的差异包括Chersobius种是多生境的,生活在干旱地区,而Homopus种生活在多生境。同人猿的雌性可以产多枚卵,与只产一枚卵的Chersobius雌性相比,它们的体型往往更大。所有物种的雌性都比同种雄性大,所有雄性的壳开口都比雌性大。ZooBank-urn: lsid zoobank.org:酒吧:18229454 - 6662 - 46 - f3 - 8去往b15 - 836 bf2ac38eb

ABSTRACT Wormian bones are accessory bones found between cranial elements. These rare bones vary greatly in size, shape and placement. Wormian bones are well-known in mammals, notably in humans and chimpanzees, but not in lizards. Here we examine the genus Zygaspis, a southern African amphisbaenian with complex cranial sutures, for the presence of Wormian bones. Skulls from seven of the eight species of Zygaspis were examined for the presence of Wormian bones. Because of their small size, complex sutures and delicate nature, high-resolution X-ray computed tomography was used to produce 3D models of the skulls. We discovered three Wormian bones in the interdigitated frontoparietal suture of Z. kafuensis. This discovery is the first known record of Wormian bones in a lizard and it is one of the few reports of them in the Squamata. The presence of Wormian bones in a head-first, burrowing squamate allows for a possible functional role to be hypothesised. Additional studies on a variety of squamate taxa are now needed, particularly in burrowing groups with interdigitated sutures, to improve our understanding of these rare cranial elements.
沃米安骨是发现于颅骨元素之间的附属骨骼。这些罕见的骨头在大小、形状和位置上都有很大的差异。Wormian骨骼在哺乳动物中很常见,尤其是在人类和黑猩猩中,但在蜥蜴中则不然。在这里,我们检查了Zygaspis属,一种具有复杂颅骨缝合线的南非两栖动物,是否存在Wormian骨骼。对八种Zygaspis中的七种的头骨进行了Wormian骨骼的检查。由于它们体积小、缝合复杂、性质细腻,高分辨率X射线计算机断层扫描被用于制作头骨的3D模型。我们在卡氏Z.kafuensis的额顶叉缝中发现了三块Wormian骨头。这一发现是已知的第一个蜥蜴Wormian骨骼的记录,也是Squamata为数不多的关于它们的报告之一。Wormian骨头存在于一只头部优先、洞穴化的乳鸽中,这使得人们可以假设其可能的功能作用。现在需要对各种鳞片分类群进行更多的研究,特别是在具有叉指缝合线的洞穴群中,以提高我们对这些罕见颅骨元素的理解。

ABSTRACT Donald G. Broadley was one of Africa’s most prolific recent authors. He produced over 410 articles, including numerous comprehensive and detailed taxonomic reviews of lizard and snake genera. A review of his scientific publications spanning over 50 years of herpetological research reveals three phases. The first (1958–1981) saw Don describe his first new reptile and the completion of numerous important generic revisions. The second phase (1982–1991) was a period of relative taxonomic quiescence, but saw the compilation of major faunal overviews, including two books, the monographic Amphibia Zambesiaca (with J.C. Poynton, 1985–1991), and a checklist of the reptiles of Tanzania (with Kim Howell, 1991). The third and final phase of Don’s career (1992–2015) saw him at the peak of both his collaborative and authoritative stage. His outlook embraced sub-Saharan Africa, although always with a bias towards eastern and southern Africa. Appendices include: a detailed bibliography of his herpetological publications; a chronological list of all the scientific taxa he described; and details of the numerous current patronyms named in his honour. He described 123 taxa, including 115 species/subspecies and 8 genera/subgenera. As of 2016 there are 16 patronyms (five amphibians, nine reptiles and two invertebrates) named in his honour.
唐纳德·g·布罗德利是非洲近年来最多产的作家之一。他发表了410多篇文章,其中包括许多全面而详细的蜥蜴和蛇属分类评论。回顾他50多年来的爬行动物研究的科学出版物,可以发现三个阶段。第一次(1958-1981),唐描述了他的第一个新的爬行动物,并完成了许多重要的通用修订。第二阶段(1982-1991年)是分类学相对平静的时期,但完成了主要动物群概述的汇编,包括两本书:专著《赞比亚两栖》(与J.C. Poynton合著,1985-1991年)和坦桑尼亚爬行动物清单(与Kim Howell合著,1991年)。唐职业生涯的第三个也是最后一个阶段(1992-2015)见证了他在合作和权威阶段的巅峰。他的观点包括撒哈拉以南非洲,尽管总是对东部和南部非洲有偏见。附录包括:他的爬虫类出版物的详细参考书目;他所描述的所有科学分类群的时间顺序表;以及众多以他命名的父姓的细节。描述了123个分类群,包括115个种/亚种和8个属/亚属。截至2016年,有16个父名(5个两栖动物,9个爬行动物和2个无脊椎动物)以他的名字命名。
