    A Guide to the Reptiles and Amphibians of Egypt
    Book Description:

    Reptiles and amphibians are among Egypt’s most successful wildlife, found in almost every habitat in the country, from homes to fields and the desert itself. For the first time, A Guide to the Reptiles and Amphibians of Egypt provides concise, reliable, and up-to-date information on all of Egypt’s principal species, with detailed material on their taxonomy, identification, natural history, and ecology. Based on fifteen years of fieldwork, this guide is a valuable tool for experts and amateurs alike in the identification, study, and conservation of these fascinating animals. With an easy-to-use key, high-quality maps, and over 100 color illustrations, this field guide covers 110 species—including tortoises and turtles, lizards, snakes, and crocodiles—found in Egypt. Each entry contains concise information about the species, including English, Latin, and Arabic names; world and Egypt distribution; distinguishing features; habitat and ecology; behavior; and conservation status. Included too are line drawings to illustrate key identification features and differences between species. With a comprehensive bibliography for further research, the guide supplies the accuracy and scientific rigor that scientists look for, while providing an accessible approach for generalists and amateurs. For biologists, nature lovers, and anyone interested in Egypt’s rich natural heritage, A Guide to the Reptiles and Amphibians of Egypt is an ideal reference tool.

    The knowledge of our biodiversity resources is still far from complete. Understanding and accounting for our biodiversity is essential if we are to develop meaningful and effective strategies and actions for their future conservation. The present treatise is an excellent example of biodiversity survey, which updates and consolidates our knowledge about an important part of the Egyptian fauna, the herpetofauna. This fauna deserves special attention particularly the amphibia, turtles and tortoises, which are among the most threatened groups of biota worldwide.

    The introductory chapter provides a synoptic outline of the scene of Egypt: its diverse deserts, oases, Nile Valley and...

  5. Introduction
    (pp. xi-xii)

    The Egyptian fauna has been documented and investigated for a long time, probably longer than any other fauna in the world, dating back to pharaonic times. The herpetofauna received special attention from the ancient Egyptians, who depicted many reptile species in their inscriptions, such as CobrasNajasp., Horned ViperCerastes cerastes, Nile CrocodilesCrocodylus niloticus, and Dab LizardsUromastyxsp. Throughout the eighteenth and nineteenth centuries Egypt was a popular destination for naturalists and explorers, becoming an important source of material used in describing many taxa after the establishment of the Linnaean nomenclature system. In more recent times, Egyptian...

  6. Chapter 1 The Egyptian Setting
    (pp. 1-2)

    Egypt occupies the northeastern corner of the African continent, with a surface area of just over one million square kilometers (1,019,600 km), or about 3% of the total area of Africa (Zahran and Willis 1992). The country is situated within the largest and driest desert region on the globe, with one of the world's largest rivers running through it. Egypt can be divided into four major terrestrial physiographic regions: the Nile Valley, Western Desert, Eastern Desert, and Sinai (Kassas 1993); and two marine regions: the Mediterranean and Red Sea. Perhaps the most outstanding feature of Egypt’s landscape is the Nile...

  7. Chapter 2 Evolution of Egypt’s Landscape and Its Herpetofauna
    (pp. 3-6)

    The contemporary Egyptian landscape is the outcome of millions of years of geological evolution. However, the events that took place since the early Miocene (25 MYBP) have had the greatest impact in shaping the present-day structural framework of Egypt (Said 1990). It is in this period that Egypt reached roughly its current shape and size, the Nile River was born, and the Arabian Plate drifted away from Africa to open up the Red Sea.

    The Red Sea, the principal migration barrier between Arabia and Africa, is relatively young (Joger 1987). Early Miocene rifting produced the Gulf of Suez and widened...

  8. Chapter 3 The Contemporary Egyptian Herpetofauna
    (pp. 7-12)

    The contemporary Egyptian herpetofauna encompasses at least 118 species, composed of nine species of amphibians, sixty-one lizards, thirty-nine snakes, one crocodile, seven species of turtles and a tortoise. In total the current work adds almost 20% to the previously reported fauna, including some twenty species not reported in the last published herpetofaunal review of the country (Saleh 1997).

    Contributions to the herpetological knowledge of Egypt leading up to this volume include six new species:Bufo kassasii, Hemidactylus foudaii, H. mindiae, Tarentola mindiae, Tropiocolotes bisharicus,andT. nubicus. An additional fourteen species are reported from Egypt for the first time (in...

  9. Chapter 4 Herpetofaunal Habitats of Egypt
    (pp. 13-18)

    Egypt enjoys a considerable diversity of habitats and vegetation types, despite its predominantly hyper-arid environment, and this habitat diversity supports a corresponding diversity of faunal elements (Kassas 1993). This can be attributed to the fairly varied landscape of the country, and its geographic position, which places Egypt under the influence of several climatic patterns. The contemporary assemblage of habitats in Egypt is the outcome of complex ecological processes, and interactions between the physical environment, climate, and biota over millennia.

    The vast majority of Egypt's territory is made up of desert. Despite their image as lifeless, monotonous parts of the world,...

  10. Chapter 5 Conservation
    (pp. 19-20)

    Most Egyptian reptile and amphibian species are not protected by law. Law 4 for 1994 is the main legislation currently offering protection to species of wildlife. The main weakness in current legislation is in the executive regulations, which designate a list of protected species based on scattered decrees issued previously by the Ministry of Agriculture. Only fifteen species are thus specifically protected by Egyptian legislation:Uromastyx aegyptia, U. ocellata, U. ornate, Chamaeleo africanus, C. chamaeleon, Varanus griseus, V. niloticus, Eryx colubrinus, E. jaculus, Walterinnesia aegyptia, Crocodylus niloticus, Testudo kleinmanni, Chelonia mydas, Eretmochelys imbricata,andTrionyx triunguis. Some of these species...

  11. Chapter 6 Methodology
    (pp. 21-24)

    More than ten thousand reptile and amphibian specimens originating from Egypt were examined in the various institutions visited, and in the author’s private collection. Material collected from Egypt of all 118 taxa recorded in the country was examined, with the exception ofLycophidion capense, Dolichophis jugularis,andLepidochelys olivacea. Materials and literature resources in the following institutions were utilized: Natural History Museum, London; Field Museum of Natural History, Chicago; National Museum of Natural History, Washington, D.C.; Museum of Comparative Zoology, Cambridge, Massachusetts; California Academy of Sciences, San Francisco; Museum of Vertebrate Zoology, Berkeley; and Koenig Museum, Bonn. Important specimens from...

  12. Chapter 7 Amphibia
    (pp. 25-26)

    The amphibian fauna of Egypt is rather poor, which is not surprising given that 95% of the country consists of desert. Toads and frogs (Anura) are the only amphibians known from Egypt: tailed amphibians (Caudata) have not been found in the country. In total there are 4 toads and 3 frogs known from Egypt....

    (pp. 53-114)

    Mostly nocturnal lizards. There are at least 24 species belonging to 7 genera known to be represented in Egypt. Gekkonids are well diversified in arid lands because of their special capacity for tolerating the harsh desert conditions. Most Egyptian taxa are nocturnal, allowing them to avoid the tough conditions of the daytime. Because of their nocturnal and reclusive habits they are also not very well studied. During the past 8 years 5 gecko species new to science have been described in Egypt. Geckos inhabit all habitats of the country, from littoral scrub, sand dunes, and mountains to the mesic habitats...
