  • A Comparative Study of the Thermal Tolerance of Tadpoles of Iberian Anurans
    Universidade de Lisboa Faculdade de Ciências Departamento de Biologia Animal A comparative study of the thermal tolerance of tadpoles of Iberian anurans Helder Santos Duarte Mestrado em Biologia da Conservação 2011 Universidade de Lisboa Faculdade de Ciências Departamento de Biologia Animal A comparative study of the thermal tolerance of tadpoles of Iberian anurans Helder Santos Duarte Mestrado em Biologia da Conservação 2011 Dissertação orientada por Prof. Dr. José Pedro Sousa do Amaral e Prof. Dr. Rui Rebelo Departamento de Biologia Animal, Faculdade de Ciências, Universidade de Lisboa i ABSTRACT The study of climate change and its impacts on biodiversity is essential for a correct and responsible assessment of population declines and potential extinction risks. Being the most threatened group of vertebrates, amphibians are being put on the edge mainly by habitat destruction and emerging infectious diseases, and possibly even more so with the added effects of global warming. We suggested that populations of anurans on latitudinal extremes of their Iberian geographic distribution would have differential responses to heat stress, whether by phylogenetic inertia or by physiological adaptation of individuals. We tested for this prediction by measuring the Critical Thermal maxima (CTmax) of 15 anuran species from the Iberian Peninsula. In seven of these species, we studied populations from the northern and southern extremes of their distributions. CTmax of Iberian anurans defined thermally distinct groups that reflect their thermal ecology and breeding phenologies. CTmax ranges show an association to geographic distribution range in the majority of species. Upper thermal tolerances did not exhibit a phylogenetic pattern and revealed to be a conservative character within species.

Unexpectedly, our genetic analyses show thatA. maurus presents a low level of variability in the mitochondrial genes with no clear geographical structuring. The low genetic variation in mtDNA can be explained by a much broader climatic suitability during the Last Glacial Maximum that allowed the connection among populations and subsequent homogenization as a consequence of gene flow.

  • 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].

  • Ageing and Growth of the Endangered Midwife Toad Alytes Muletensis

Our work presents, for the first time, growth curves and measurements of mean longevity, growth rates and age at maturity for the Vulnerable midwife toad Alytes muletensis. Von Bertalanffy growth models were used to estimate longevity and growth rate parameters. Females had a mean (±SD) longevity of 4.70 ± 0.19 yr, significantly higher than that of males (3.24 ± 0.10 yr). The maximum estimated longevity was 18 yr for both males and females. The age distribution indicated that males reached sexual maturity at the age of 1 yr, and most females at 2 yr. There were significant differences in growth rate between sexes, with higher values in females during the first 4 yr of life, and similar values in both sexes thereafter. These life-history traits were compared with equivalent measures in the closely related amphibian genera Bombina and Discoglossus.

Alytes muletensis is a frog endemic to the Balearic island of Majorca (or Mallorca). Its tadpole lives in semi-per- manent plunge pools which remain after mountain streams have dried up. Little is known about the morphology of the different members of the Alytidae and the relationships of its members are still unclear. Alytidae are among the most basal anurans, and improved knowledge of their larval morphology can contribute to our understanding of the morphological evolution of anurans. Herein, I describe the external morphology as well as skeletal and muscular features of a tadpole of A. muletensis at Gosner stage 25 by using standard histology, clearing and staining and 3D-reconstruction based on serial sections. The tadpole displays different discoglossoid traits such as the presence of two portions of the M. levator mandibu- lae externus, the separation of hypobranchial elements by the basibranchial, and the absence of the M. constrictor branchia- lis IV, among others. Unusual is the absence of the M. constrictor branchialis I as well as the absence of the M. intermand- ibularis. Remarkable is the presence of the admandibular cartilage as an additional skeletal element of the lower jaw.

  • The Rediscovered Hula Painted Frog Is a Living Fossil
    ARTICLE Received 30 Oct 2012 | Accepted 30 Apr 2013 | Published 4 Jun 2013 DOI: 10.1038/ncomms2959 The rediscovered Hula painted frog is a living fossil Rebecca Biton1, Eli Geffen2, Miguel Vences3, Orly Cohen2, Salvador Bailon4, Rivka Rabinovich1,5, Yoram Malka6, Talya Oron6, Renaud Boistel7, Vlad Brumfeld8 & Sarig Gafny9 Amphibian declines are seen as an indicator of the onset of a sixth mass extinction of life on earth. Because of a combination of factors such as habitat destruction, emerging pathogens and pollutants, over 156 amphibian species have not been seen for several decades, and 34 of these were listed as extinct by 2004. Here we report the rediscovery of the Hula painted frog, the first amphibian to have been declared extinct. We provide evidence that not only has this species survived undetected in its type locality for almost 60 years but also that it is a surviving member of an otherwise extinct genus of alytid frogs, Latonia, known only as fossils from Oligocene to Pleistocene in Europe. The survival of this living fossil is a striking example of resilience to severe habitat degradation during the past century by an amphibian. 1 National Natural History Collections, Institute of Archaeology, Hebrew University of Jerusalem, Jerusalem 91904, Israel. 2 Department of Zoology, Tel Aviv University, Tel Aviv 69978, Israel. 3 Division of Evolutionary Biology, Zoological Institute, Technical University of Braunschweig, 38106 Braunschweig, Germany. 4 De´partement Ecologie et Gestion de la Biodiversite´, Muse´um National d’Histoire Naturelle, UMR 7209–7194 du CNRS,55 rue Buffon, CP 55, Paris 75005, France. 5 Institute of Earth Sciences, Hebrew University of Jerusalem, Jerusalem 91904, Israel.
