  • Amphibians and Reptiles of the Mediterranean Basin
    Chapter 9 Amphibians and Reptiles of the Mediterranean Basin Kerim Çiçek and Oğzukan Cumhuriyet Kerim Çiçek and Oğzukan Cumhuriyet Additional information is available at the end of the chapter Additional information is available at the end of the chapter http://dx.doi.org/10.5772/intechopen.70357 Abstract The Mediterranean basin is one of the most geologically, biologically, and culturally complex region and the only case of a large sea surrounded by three continents. The chapter is focused on a diversity of Mediterranean amphibians and reptiles, discussing major threats to the species and its conservation status. There are 117 amphibians, of which 80 (68%) are endemic and 398 reptiles, of which 216 (54%) are endemic distributed throughout the Basin. While the species diversity increases in the north and west for amphibians, the reptile diversity increases from north to south and from west to east direction. Amphibians are almost twice as threatened (29%) as reptiles (14%). Habitat loss and degradation, pollution, invasive/alien species, unsustainable use, and persecution are major threats to the species. The important conservation actions should be directed to sustainable management measures and legal protection of endangered species and their habitats, all for the future of Mediterranean biodiversity. Keywords: amphibians, conservation, Mediterranean basin, reptiles, threatened species 1. Introduction The Mediterranean basin is one of the most geologically, biologically, and culturally complex region and the only case of a large sea surrounded by Europe, Asia and Africa. The Basin was shaped by the collision of the northward-moving African-Arabian continental plate with the Eurasian continental plate which occurred on a wide range of scales and time in the course of the past 250 mya [1].

  • 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).

  • Reconstructing Ancestral Trait Values Using Squared
    426 T. Garland Jr., K. L. M. Martin, R. Diaz-Uriarte Usually, however, one is limited to a consideration of "ordinary" extant organisms as "models" for extinct forms (e.g., Ruben and Bennett, 1980; Burggren and Benis, 1990; Ruben, 1991; Ruben and Parrish, 1991; Janis and Wilhelm, 1993; Garland and Carter, 1994; 1 Hackstein and van Alen, 1996; Ruben et al., 1996). The purpose of this chapter is to illustrate some ways in which data on the RECONSTRUCTINGANCESTRAL TRAIT VALUES characteristics of living organisms can be combined with phylogenetic information and recently developed analytical methods to make USINGSQUARED-CHANGE PARSIMONY: PLASMA inferences about the characteristics of hypothetical ancestral OSMOLARITYAT THE ORIGINOF AMNIOTES organisms. For illustrative purposes, the phenotypic trait we consider is plasma osmolarity, which previous (nonphylogenetic) studies have shown to vary among phylogenetic lineages (clades) and in relation to ecology or habitat (e.g., freshurater versus saltwater). We have Theodore Garland, Jr. compiled from the literature osmolarity data for a total of 172 Karen L. M. Martin vertebrate taxa, including representatives of all major extant lineages (Figs. 1, 2, and append,^ 1). Some living forms are known to be Ramon Diaz-Uriarte highly derived as compared with their ancestors, and hence constitute "red herrings" with respect to mdcing inferences about extinct forms (Gans, 1970). Given data for a wide variety of extant organisms, therefore, which ones should be used as models for extinct forms-all or a subset? Moreover, how, exactly, should one go about making an inference regarding extinct organisms? Most simply, one could estimate the value of a trait in a hypothetical ancestor as the simple INTRODUCTION mean of the values observed in ils living descendants.

  • A Molecular Study of the Genus Agama (Squamata : Agamidae)
    Russian Journal of Herpetology Vol. 19, No. 2, 2012, pp. 115 – 142 A MOLECULAR STUDY OF THE GENUS Agama (SQUAMATA: AGAMIDAE) IN WEST AFRICA, WITH DESCRIPTION OF TWO NEW SPECIES AND A REVIEW OF THE TAXONOMY, GEOGRAPHIC DISTRIBUTION, AND ECOLOGY OF CURRENTLY RECOGNIZED SPECIES Oleg Mediannikov,1 Sébastien Trape,2 and Jean-François Trape1,3 Submitted March 25, 2011. We conducted field studies in 15 West African countries and collected one thousand specimens of lizards of the genus Agama. Based on these collections, literature, molecular analysis of selected specimens, and examination of Linnean type-specimens of A. agama, we review the phylogeny, taxonomy, geographic distribution and ecology of the West African species of the genus Agama. Seventeen different species are recognized in the genus Agama in West Africa, northern Cameroon and Chad: A. africana, A. agama, A. boensis, A. boueti, A. boulengeri, A. castroviejoi, A. cristata, A. doriae benueensis, A. gracilimembris, A. insularis, A. lebretoni, A. paragama, A. sankaranica, A. weidholzi, and three new species. We design a lectotype for A. agama (Linnaeus, 1758) and attribute to A. wagneri, sp. nov., the populations from northern and central Cameroon of the A. agama complex. Agama parafricana, sp. nov., is described from wet savanna areas of Togo and Benin. Agama sylvanus from south- ern Ghana is a junior synonym of A. africana. Agama cf. impalearis from northern Niger and Mali corresponds to an nondescribed species. Agama boensis is resurrected from the synonymy of A. sankaranica. According to biogeographic areas, four species are Sahelian, seven species are Sudanian, four species are Guinean, and two species are ubiquitous.

  • Evolution of Developmental Sequences in Lepidosaurs
    Evolution of developmental sequences in lepidosaurs Tomasz Skawi«ski and Bartosz Borczyk Department of Evolutionary Biology and Conservation of Vertebrates, University of Wroclaw, Wrocªaw, Poland ABSTRACT Background. Lepidosaurs, a group including rhynchocephalians and squamates, are one of the major clades of extant vertebrates. Although there has been extensive phylo- genetic work on this clade, its interrelationships are a matter of debate. Morphological and molecular data suggest very different relationships within squamates. Despite this, relatively few studies have assessed the utility of other types of data for inferring squamate phylogeny. Methods. We used developmental sequences of 20 events in 29 species of lepidosaurs. These sequences were analysed using event-pairing and continuous analysis. They were transformed into cladistic characters and analysed in TNT. Ancestral state reconstructions were performed on two main phylogenetic hypotheses of squamates (morphological and molecular). Results. Cladistic analyses conducted using characters generated by these methods do not resemble any previously published phylogeny. Ancestral state reconstructions are equally consistent with both morphological and molecular hypotheses of squamate phylogeny. Only several inferred heterochronic events are common to all methods and phylogenies. Discussion. Results of the cladistic analyses, and the fact that reconstructions of heterochronic events show more similarities between certain methods rather than phylogenetic hypotheses, suggest that

  • Heat Tolerance of Reptile Embryos in a Changing World: Physiological Mechanisms and Ecological Effects
    Heat tolerance of reptile embryos in a changing world: Physiological mechanisms and ecological effects by Joshua Matthew Hall A dissertation submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Doctor of Philosophy Auburn, Alabama August 8, 2020 Keywords: Anolis, climate change, critical thermal maximum, developmental plasticity, heat stress, lethal temperature, oxygen-limited thermal tolerance, urbanization Approved by Daniel Warner, Chair, Assistant Professor, Department of Biological Sciences Craig Guyer, Professor Emeritus, Department of Biological Sciences Haruka Wada, Assistant Professor, Department of Biological Sciences Jim Stoeckel, Associate Professor, School of Fisheries, Aquaculture, and Aquatic Sciences Tracy Langkilde, Professor, Department of Biology, Pennsylvania State University ABSTRACT Aspects of global change (e.g. climate change, urbanization) create stressful thermal environments that threaten biodiversity. Oviparous, non-avian reptiles have received considerable attention because eggs are left to incubate under prevailing conditions, leaving developing embryos vulnerable to increases in temperature. Though many studies assess embryo responses to long-term (i.e. chronic) incubation temperatures, few assess responses to acute exposures which are more relevant for many species and may become more common due to global change. Because warming temperatures cause increases in both mean and variance of nest temperatures, it is crucial to consider embryo responses to both chronic and acute heat stress. Currently, there are no standard metrics or terminology for determining heat stress of embryos. This impedes comparisons across studies and species and hinders our ability to predict how species will respond to warming temperatures. In Chapter 1, I compare various methods that have been used to assess embryonic heat tolerance in reptiles and provide new terminology and metrics for quantifying embryo responses to both chronic and acute heat stress.

  • Dimensions of Home Range Structure of Agama Agama in the Savanna Region of Nigeria
    Herpetological Conservation and Biology 15(2):318–324. Submitted: 20 December 2018; Accepted: 18 May 2020; Published: 31 August 2020. DIMENSIONS OF HOME RANGE STRUCTURE OF AGAMA AGAMA IN THE SAVANNA REGION OF NIGERIA SAFIANU RABIU Department of Biological Sciences, Bayero University Kano, 1 Gwarzo Road, PMB 3011, Kano 700241, Nigeria, e-mail: [email protected] Abstract.—Home Range (HR) evaluations provide data related to animal searches for food, mates, and other resources. In grasslands of Nigeria where populations of the semi-arboreal African Rainbow Lizard (Agama agama) are dense, I measured three dimensions of HR: home range area (HRA), home range length (HRL), and vertical height (VH). I surveyed 3–4 h in each of four sites between 0600–1300 and 1600–1800 over 6 d each month (June 2015 to May 2016). I recorded sighting grid coordinates and vertical positions of the lizards. After correction to 95% resolution, I programed the coordinates to calculate HRL (and VH) by Adjusted HRL method, and calculated HRA by Minimum Convex Polygon (MCP) method. Highest daily mean HRA (618 m2), HRL (63 m), and VH (262 cm) were for mature males during the dry season. Mature females, juvenile males, and juvenile females, in decreasing order, had lower means for all three dimensions of HR. Age, sex and age-sex classes, as well as seasonal changes had significant influences on mean values of HRA, HRL, and VH. Regression analysis indicated that HRL is a significant predictor of HRA. There were age-sex class frequency overlays in all HR dimensions. I recommend a multi-dimensional approach to HR investigations for A.

    Integrative inference of evolutionary patterns of desert biodiversity: a spatial and temporal multi- D scale approach using herpetofauna from North-Africa Duarte Nuno Vasconcelos Gonçalves Programa Doutoral em Biodiversidade, Genética e Evolução Departamento de Biologia 2017 Orientador José Carlos Alcobia Rogado de Brito, Investigador Principal, CIBIO-InBIO Coorientador Salvador Carranza Gil Dolz Del Castellar, Tenured Scientist, IBE (CSIC-UPF) Nota prévia Na elaboração desta tese, e nos termos do número 2 do Artigo 4o do Regulamento Geral dos Terceiros Ciclos de Estudos da Universidade do Porto e do Artigo 31º do D.L. 74/2006, de 24 de Março, com a nova redação introduzida pelo D.L. 230/2009, de 14 de Setembro, foi efetuado o aproveitamento total de um conjunto coerente de trabalhos de investigação já publicados ou submetidos para publicação em revistas internacionais indexadas e com arbitragem científica, os quais integram alguns dos capítulos da presente tese. Tendo em conta que os referidos trabalhos foram realizados com a colaboração de outros autores, o candidato esclarece que, em todos eles, participou ativamente na sua conceção, na obtenção e análise de dados, e discussão de resultados, bem como na elaboração da sua forma publicada. Este trabalho foi apoiado pela Fundação para a Ciência e Tecnologia (FCT) através da atribuição da bolsa de doutoramento (SFRH/BD/78402/2011). Acknowledgements The successful conclusion of this thesis would not have been possible without the support of several institutions, but also many people with whom I have contacted during these last few years. From academics, family and friends, and random passersby like a reckless one-eye moto-taxi driver, I got valuable insights into life that have proved and certainly will continue to prove very useful for the times to come inside and outside academia.
