  • Exploring the Host Specificity and Diversity of Haemogregarines in the Canary Islands Beatriz Tomé1,2*, Ana Pereira1,2, Fátima Jorge3, Miguel A
    Tomé et al. Parasites & Vectors (2018) 11:190 https://doi.org/10.1186/s13071-018-2760-5 RESEARCH Open Access Along for the ride or missing it altogether: exploring the host specificity and diversity of haemogregarines in the Canary Islands Beatriz Tomé1,2*, Ana Pereira1,2, Fátima Jorge3, Miguel A. Carretero1, D. James Harris1 and Ana Perera1 Abstract Background: Host-parasite relationships are expected to be strongly shaped by host specificity, a crucial factor in parasite adaptability and diversification. Because whole host communities have to be considered to assess host specificity, oceanic islands are ideal study systems given their simplified biotic assemblages. Previous studies on insular parasites suggest host range broadening during colonization. Here, we investigate the association between one parasite group (haemogregarines) and multiple sympatric hosts (of three lizard genera: Gallotia, Chalcides and Tarentola) in the Canary Islands. Given haemogregarine characteristics and insular conditions, we hypothesized low host specificity and/or occurrence of host-switching events. Methods: A total of 825 samples were collected from the three host taxa inhabiting the seven main islands of the Canarian Archipelago, including locations where the different lizards occurred in sympatry. Blood slides were screened to assess prevalence and parasitaemia, while parasite genetic diversity and phylogenetic relationships were inferred from 18S rRNA gene sequences. Results: Infection levels and diversity of haplotypes varied geographically and across host groups. Infections were found in all species of Gallotia across the seven islands, in Tarentola from Tenerife, La Gomera and La Palma, and in Chalcides from Tenerife, La Gomera and El Hierro. Gallotia lizards presented the highest parasite prevalence, parasitaemia and diversity (seven haplotypes), while the other two host groups (Chalcides and Tarentola) harbored one haplotype each, with low prevalence and parasitaemia levels, and very restricted geographical ranges.

  • A Phylogenetic History of the Tenerife Skink Chalcides Viridanus: a Multi-Locus Coalescent Approach
    A Phylogenetic History of the Tenerife Skink Chalcides viridanus: A multi-locus Coalescent Approach Matthew Woods A thesis submitted in partial fulfilment of the requirements of Liverpool John Moores University for the degree of Masters of Philosophy. March 2015 Abstract Previous studies on the Tenerife skink Chalcides viridanus found clear links between observed within-island cladogenesis and the geological history of the island. Since these studies there have been many advances in conceptual, numerical and methodological approaches in phylogenetic analyses. This study aims to revisit the phylogeography of the Tenerife skink, using more current *BEAST analysis techniques, and attempt to resolve some unanswered questions about population history of this species. Specifically, using previously unused nuclear gene markers to obtain a more robust phylogeographical history of the species, using new techniques to estimate whether any historic changes in population size can be linked to known geological events and whether there is enough evidence to reclassify any discovered genetic clades as distinct species. A multi-locus approach was undertaken, using more informative mtDNA gene fragments (Cyt- b & ND1 & 2, totalling 1566bp) as well as the sequencing of 5 nuclear loci (PRLR-555bp, Rag- 1-761bp, RELN-583bp, EXPH-796bp and SELT-414bp). These sequences were combined with the latest Bayesian methods to estimate divergence times, historical changes in population structure and infer species boundaries. Results from the BAPS and *BEAST analyses identified three main population groups within the island, the geographical distribution of two of which were restricted to the areas representing the ancient precursor islands Teno & Anaga in the North West and North East of Tenerife, respectively.

    BIOGRAPHICAL SKETCH AND BIBLIOGRAPHY OF STEPHEN D. BUSACK Stephen D. Busack Rochester, New York SMITHSONIAN HERPETOLOGICAL INFORMATION SERVICE NO. 154 2018 . SMITHSONIAN HERPETOLOGICAL INFORMATION SERVICE The first number of the SMITHSONIAN HERPETOLOGICAL INFORMATION SERVICE series appeared in 1968. SHIS number 1 was a list of herpetological publications arising from within or through the Smithsonian Institution and its collections entity, the United States National Museum (USNM). The latter exists now as little more than the occasional title for the registration activities of the National Museum of Natural History. No. 1 was prepared and printed by J. A. Peters, then Curator-in-Charge of the Division of Amphibians & Reptiles. The availability of a NASA translation service and assorted indices encouraged him to continue the series and distribute these items on an irregular schedule. The series continues under that tradition. Specifically, the SHIS series distributes translations, bibliographies, indices, and similar items judged useful to individuals interested in the biology of amphibians and reptiles, and unlikely to be published in the normal technical journals. We wish to encourage individuals to share their bibliographies, translations, etc. with other herpetologists through the SHIS series. If you have such an item, please contact George Zug [zugg @ si.edu] for its consideration for distribution through the SHIS series. Our increasingly digital world is changing the manner of our access to research literature and that is now true for SHIS publications. They are distributed now as pdf documents through two Smithsonian outlets: BIODIVERSITY HERITAGE LIBRARY. www.biodiversitylibrary.org/bibliography/15728 All numbers from 1 to 131 [1968-2001] available in BHL.

Abstract Sequences from fragments of the 12s ribosomal RNA and cytochrome b mito- chondrial genes were used to analyze phylogenetic relationships among geckos of genus Turentolu from the Canary Islands. A surprisingly high level of within island differentiation was found in T. delulundii in Tenerife and T. boettgeri in Gran Canaria. Molecular differentiation between populations of T. ungustimentulis on Lanzarote and Fuerteventura, and between Moroccan and Iberian Peninsula T. muuritunicu, also indicate that at least two subspecies should be recognized within each of them. Phylogenetic relationships among these species reveals a higher level of differentiation and a more complex colonization pattern than those found for the endemic genus Gullotiu. Lack of evidence for the presence of T. boettgeri bischoffi on the island of Madeira does not seem to support the origin of T. delulundii, T. gomerensis and the canarian subspecies of T, boettgeri from this island, whereas molecular data confirms that T. ungustimentulis is a sister species of the continental T.

ABSTRACT Dietary studies can reveal valuable information on how species exploit their habitats and are of particular importance for insular endemics conservation as these species present higher risk of extinction. Reptiles are often neglected in island systems, principally the ones inhabiting remote areas, therefore little is known on their ecological networks. The Selvagens gecko Tarentola (boettgeri) bischoffi, endemic to the remote and integral reserve of Selvagens Archipelago, is classified as Vulnerable by the Portuguese Red Data Book. Little is known about this gecko's ecology and dietary habits, but it is assumed to be exclusively insectivorous. The diet of the continental Tarentola species was already studied using classical methods. Only two studies have used next-generation sequencing (NGS) techniques for this genus thus far, and very few NGS studies have been employed for reptiles in general. Considering the lack of information on its diet Submitted 10 April 2019 and the conservation interest of the Selvagens gecko, we used morphological and Accepted 22 October 2019 Published 2 January 2020 DNA metabarcoding approaches to characterize its diet.

This is probably the most well known location on Tenerife as it is where most people see their first Blue Chaffinches and we were not to be disappointed. Also at this location we saw the only Great Spotted Woodpecker of the tour plus a few Canaries, a Tenerife Kinglet and a few African Blue Tits. After departing from Las Lajas we continued climbing and entered the Las Cañadas National Park which is a spectacular drive through volcanic scenery. On the drive we encountered quite a few endemic plants including Pinus canariensis and Spartocytisus supranubius that were common and easily recognized and Echium wildpretii, Pterocephalus lasiospermus, Descurainia bourgaeana and Argyranthemum teneriffae which were rather unimpressive as they were not yet flowering but we were compensated by the fabulous views across the ancient caldera.

Studies on tongue of reptilian species Psammophis sibilans, Tarentola annularis and Crocodylus niloticus. Int. J. Morphol., 29(4):1139-1147, 2011. SUMMARY: Three different reptilian species Psammophis sibilans (Order Ophidia), Tarentola annularis (Order Squamata and Crocodylus niloticus (Order Crocodylia) are used in the present study. Their tongue is removed and examined morphologically. Their lingual mucosa examined under scanning electron microscopy (SEM) as well as processed for histological investigation. Gross morphological studies revealed variations of tongue gross structure being elongated with bifurcated end in P. sibilans or triangular flattened structure with broad base and conical free border in T. annularis or rough triangular fill almost the floor cavity in C. niloticus. At SEM, the lingual mucosa showed fine striated grooves radially arranged in oblique extension with missing of lingual papillae. Numerous microridges are detected above the cell surfaces in P. sibilans. T. annularis exhibited arrangement of conical flattened filiform papillae and abundant of microridges. However in C. niloticus, the lingual mucosa possessed different kinds of filiform papillae besides gustatory papillae and widespread arrangement of taste buds.

  • Checklist of Amphibians and Reptiles of Morocco: a Taxonomic Update and Standard Arabic Names
    Herpetology Notes, volume 14: 1-14 (2021) (published online on 08 January 2021) Checklist of amphibians and reptiles of Morocco: A taxonomic update and standard Arabic names Abdellah Bouazza1,*, El Hassan El Mouden2, and Abdeslam Rihane3,4 Abstract. Morocco has one of the highest levels of biodiversity and endemism in the Western Palaearctic, which is mainly attributable to the country’s complex topographic and climatic patterns that favoured allopatric speciation. Taxonomic studies of Moroccan amphibians and reptiles have increased noticeably during the last few decades, including the recognition of new species and the revision of other taxa. In this study, we provide a taxonomically updated checklist and notes on nomenclatural changes based on studies published before April 2020. The updated checklist includes 130 extant species (i.e., 14 amphibians and 116 reptiles, including six sea turtles), increasing considerably the number of species compared to previous recent assessments. Arabic names of the species are also provided as a response to the demands of many Moroccan naturalists. Keywords. North Africa, Morocco, Herpetofauna, Species list, Nomenclature Introduction mya) led to a major faunal exchange (e.g., Blain et al., 2013; Mendes et al., 2017) and the climatic events that Morocco has one of the most varied herpetofauna occurred since Miocene and during Plio-Pleistocene in the Western Palearctic and the highest diversities (i.e., shift from tropical to arid environments) promoted of endemism and European relict species among allopatric speciation (e.g., Escoriza et al., 2006; Salvi North African reptiles (Bons and Geniez, 1996; et al., 2018).

It is widespread in most of the anthropogenic areas, where it shows predating behavior and male territoriality, especially during breeding season. In this note, we report an atypical aggregation of this species found in the streetlamps of the most frequented area of a campsite in Ronda, Malaga, Spain. There are previously reported T. mauritanica diurnal aggregations in retreat sites, but not much information can be found related to the interaction among reptiles in small places with high prey availability. This unusual tolerance to the presence of other males in such a reduced but suitable place for predating as a spotlight near humid facilities could be explained as an adaptive strategy to increase their success in hunting.
