Die längsten erythrozyten fanden sich bei S. grandiceps , die breitesten und größten bei A. barani , die kür - zesten bei C. scabrum , die schmalsten bei M. kotschyi und die kleinsten bei C. scabrum . Die längsten und größ - ten erythrozytenkerne wurden bei M. heterocercus , die kürzesten, schmalsten und kleinsten bei M. kotschyi und die größten bei A. barani gemessen . Bezüglich des verhältnisses von Länge zu Breite, kamen die länglichsten erythrozyten bei S. grandiceps , die rundlichsten bei M. kotschyi vor. Die kern-plasma-relation zeigte bei C. sca - brum und M. heterocercus den größten, bei S. grandiceps den geringsten Wert. Die kern-plasma-relation türki - scher Geckos war ähnlich der bei türkischen Lacertiden. Zwischen den untersuchten Geckoarten bestanden beträchtliche unterschiede in der Gestalt der erythrozyten und ihrer kerne, während das für die Leukozytenmorphologie nicht zutraf. Lymphozyten waren die häufigsten Leukozyten bei allen Arten. Die kerne der eosinophilen und basophilen Granulozyten waren durch die starke körnung des Zytoplasmas undeutlich. Die thrombozyten waren bei allen Arten flach ellipsoidisch. ABstrACt size parameters of peripheral blood cells (erythrocytes, leucocytes, thrombocytes) obtained from blood smears stained with Wright’s stain are given for six species of turkish gekkonid lizards: Asaccus barani torki , AhmADZADeh , i LGAZ , A vCi & k umLutAs , 2011 , Mediodactylus heterocercus (B LAnForD , 1874) , Mediodactylus kotschyi (s teinDAChner , 1870) , Cyrtopodion scabrum (h eyDen , 1827) , Hemidactylus turcicus (L innAeus , 1758) and Stenodactylus grandiceps hAAs , 1952 . the longest erythrocytes were found in S. grandiceps , the widest and largest in A. barani , the shortest in C. scabrum, the narrowest in M. kotschyi and the smallest in C. scabrum . the longest and biggest erythrocyte nuclei were measured in M. heterocercus , the shortest, narrowest and smallest in M. kotschyi and the largest in A. barani. regarding their length-to-width ratio, the most oblong erythrocytes were found in S. grandiceps , the most roundish in M. kotschyi . the value of the nucleocytoplasmic ratio was highest in C. scabrum and M. heterocercus , and low - est in S. grandiceps . the nucleocytoplasmic ratio of the gekkonid erythrocytes was similar as in lacertids. Among the species studied, erythrocyte and nucleus morphology showed considerable variation, whereas, leukocyte morphology did not. Lymphocytes outnumbered the other leucocytes in all species. the nuclei of eosinophils and basophils were not distinct because of intense granulation of the cytoplasm. the thrombocytes were the shape of a flattened ellipsoid in all species. key WorDs reptilia: squamata: sauria: phyllodactylidae, Asaccus barani ; Gekkonidae, Cyrtopodion scabrum , Hemidactylus turcicus , Mediodactylus heterocercus , Mediodactylus kotschyi , Stenodactylus grandiceps , blood smears, blood cell morphology, physiology, turkey introDuCtion Blood analyses are widely used tools help to indicate ecosystem health ( Deem et in the diagnosis and monitoring of animal al. 2006). the cellular metabolism, its homeo - health and disease and the differentiation of static control mechanisms and cellular con - physiological processes ( Christopher et al. figuration are optimized for specific require - 1999). these techniques are applied with ments and temperature ranges.

  • A Review of Southern Iraq Herpetofauna
    Vol. 3 (1): 61-71, 2019 A Review of Southern Iraq Herpetofauna Nadir A. Salman Mazaya University College, Dhi Qar, Iraq *Corresponding author: [email protected] Abstract: The present review discussed the species diversity of herpetofauna in southern Iraq due to their scientific and national interests. The review includes a historical record for the herpetofaunal studies in Iraq since the earlier investigations of the 1920s and 1950s along with the more recent taxonomic trials in the following years. It appeared that, little is known about Iraqi herpetofauna, and no comprehensive checklist has been done for these species. So far, 96 species of reptiles and amphibians have been recorded from Iraq, but only a relatively small proportion of them occur in the southern marshes. The marshes act as key habitat for globally endangered species and as a potential for as yet unexplored amphibian and reptile diversity. Despite the lack of precise localities, the tree frog Hyla savignyi, the marsh frog Pelophylax ridibunda and the green toad Bufo viridis are found in the marshes. Common reptiles in the marshes include the Caspian terrapin (Clemmys caspia), the soft-shell turtle (Trionyx euphraticus), the Euphrates softshell turtle (Rafetus euphraticus), geckos of the genus Hemidactylus, two species of skinks (Trachylepis aurata and Mabuya vittata) and a variety of snakes of the genus Coluber, the spotted sand boa (Eryx jaculus), tessellated water snake (Natrix tessellata) and Gray's desert racer (Coluber ventromaculatus). More recently, a new record for the keeled gecko, Cyrtopodion scabrum and the saw-scaled viper (Echis carinatus sochureki) was reported. The IUCN Red List includes six terrestrial and six aquatic amphibian species.

Box 4783, Abu Dhabi, United Arab Emirates Abstract.—This paper provides an updated checklist of the United Arab Emirates (UAE) native and alien herpetofauna. The UAE, while largely a desert country with a hyper-arid climate, also has a range of more mesic habitats such as islands, mountains, and wadis. As such it has a diverse native herpetofauna of at least 72 species as follows: two amphibian species (Bufonidae), five marine turtle species (Cheloniidae [four] and Dermochelyidae [one]), 42 lizard species (Agamidae [six], Gekkonidae [19], Lacertidae [10], Scincidae [six], and Varanidae [one]), a single amphisbaenian, and 22 snake species (Leptotyphlopidae [one], Boidae [one], Colubridae [seven], Hydrophiidae [nine], and Viperidae [four]). Additionally, we recorded at least eight alien species, although only the Brahminy Blind Snake (Ramphotyplops braminus) appears to have become naturalized. We also list legislation and international conventions pertinent to the herpetofauna. Key Words.— amphibians; checklist; invasive; reptiles; United Arab Emirates INTRODUCTION (Arnold 1984, 1986; Balletto et al. 1985; Gasperetti 1988; Leviton et al. 1992; Gasperetti et al. 1993; Egan The United Arab Emirates (UAE) is a federation of 2007).

  • 19 GEKKONIDAE Cyrtopodion Scabrum Heyden, 1827 Keeled Rock Gecko PREDATION on 22 July 2009 at 09H00 I Observed an Adult Cyrtopod
    AFRICAN HERP NEWS 49, DECEMBER 2009 GEKKONIDAE Cyrtopodion scabrum Heyden, 1827 Keeled Rock Gecko PREDATION On 22 July 2009 at 09h00 I observed an adult Cyrtopodion scabrum fall prey to a Great Grey Shrike ( Lanius excubitor ) whilst exposed and moving between rocks recently disturbed during maintenance activities. C. scabrum are generally viewed as anthropogenous nocturnal semi-terrestrial geckos that forage on insects around sources of artificial light (Werner, 1991; Disi et al., 2001). This small to medium sized gecko is widely distributed from Eritrea through to Pakistan including most of the Arabian Peninsula (Leviton et al. , 1992; Disi et al. , 2001). As a smallish nocturnal gecko it’s predators are expected to be many although diurnal avian predators were not expected. The situation which led to this specific individual’s demise was out of the ordinary. During maintenance work at the King Khalid Wildlife Research Centre in central Saudi Arabia, approximately 80 km north of Riyadh, I noticed a C. scabrum moving around on rocks after having been disturbed, seemingly searching for an alternative hiding place. Whilst I was observing this an adult Great Grey Shrike perched nearby and showed interest in the distressed gecko, although it was initially put off by my presence. After a while hunger overcame prudence and the shrike attacked the gecko, seized it behind the head and consumed it, including the tail which the gecko had shed on being caught. Shrikes are often considered raptor-like passerines preying mainly on a diverse range of invertebrates (mainly insects) and small vertebrates (Cramp & Perrins, 1993) including smaller birds (e.g.

  • Systematics and Biogeography of Stenodactylus Geckos
    Metallinou et al. BMC Evolutionary Biology 2012, 12:258 http://www.biomedcentral.com/1471-2148/12/258 RESEARCH ARTICLE Open Access Conquering the Sahara and Arabian deserts: systematics and biogeography of Stenodactylus geckos (Reptilia: Gekkonidae) Margarita Metallinou1, Edwin Nicholas Arnold2, Pierre-André Crochet3, Philippe Geniez4, José Carlos Brito5, Petros Lymberakis6, Sherif Baha El Din7, Roberto Sindaco8, Michael Robinson9 and Salvador Carranza1* Abstract Background: The evolutionary history of the biota of North Africa and Arabia is inextricably tied to the complex geological and climatic evolution that gave rise to the prevalent deserts of these areas. Reptiles constitute an exemplary group in the study of the arid environments with numerous well-adapted members, while recent studies using reptiles as models have unveiled interesting biogeographical and diversification patterns. In this study, we include 207 specimens belonging to all 12 recognized species of the genus Stenodactylus. Molecular phylogenies inferred using two mitochondrial (12S rRNA and 16S rRNA) and two nuclear (c-mos and RAG-2) markers are employed to obtain a robust time-calibrated phylogeny, as the base to investigate the inter- and intraspecific relationships and to elucidate the biogeographical history of Stenodactylus, a genus with a large distribution range including the arid and hyper-arid areas of North Africa and Arabia. Results: The phylogenetic analyses of molecular data reveal the existence of three major clades within the genus Stenodactylus, which is supported by previous studies based on morphology. Estimated divergence times between clades and sub-clades are shown to correlate with major geological events of the region, the most important of which is the opening of the Red Sea, while climatic instability in the Miocene is hypothesized to have triggered diversification.

  • Synanthropic Spiders, Including the Global Invasive Noble False Widow
    www.nature.com/scientificreports OPEN Synanthropic spiders, including the global invasive noble false widow Steatoda nobilis, are reservoirs for medically important and antibiotic resistant bacteria John P. Dunbar1,5*, Neyaz A. Khan2,5, Cathy L. Abberton3, Pearce Brosnan3, Jennifer Murphy3, Sam Afoullouss4, Vincent O’Flaherty2,3, Michel M. Dugon1 & Aoife Boyd2 The false widow spider Steatoda nobilis is associated with bites which develop bacterial infections that are sometimes unresponsive to antibiotics. These could be secondary infections derived from opportunistic bacteria on the skin or infections directly vectored by the spider. In this study, we investigated whether it is plausible for S. nobilis and other synanthropic European spiders to vector bacteria during a bite, by seeking to identify bacteria with pathogenic potential on the spiders. 11 genera of bacteria were identifed through 16S rRNA sequencing from the body surfaces and chelicerae of S. nobilis, and two native spiders: Amaurobius similis and Eratigena atrica. Out of 22 bacterial species isolated from S. nobilis, 12 were related to human pathogenicity among which Staphylococcus epidermidis, Kluyvera intermedia, Rothia mucilaginosa and Pseudomonas putida are recognized as class 2 pathogens. The isolates varied in their antibiotic susceptibility: Pseudomonas putida, Staphylococcus capitis and Staphylococcus edaphicus showed the highest extent of resistance, to three antibiotics in total. On the other hand, all bacteria recovered from S. nobilis were susceptible to ciprofoxacin. Our study demonstrates that S. nobilis does carry opportunistic pathogenic bacteria on its body surfaces and chelicerae. Therefore, some post-bite infections could be the result of vector- borne bacterial zoonoses that may be antibiotic resistant. Bacterial infections represent a major threat to human health.

Abo-Eleneen2 1Department of Zoology, Faculty of Science, Mansoura University, Egypt. 2 Department of Zoology, Faculty of Science, Beni-Suef University, Beni-Suef, Egypt. Accepted 31 January, 2013 The aim of this study is to show the osteological characters of the fore- and hind-limbs and the locomotion features in some reptilian species: Laudakia stellio, Hemidactylus turcicus, Acanthodatylus scutellatus, Chalcides ocellatus, Chamaeleo chamaeleon, collected from different localities from Egypt desert and Varanus griseus from lake Nassir in Egypt. In the studied species, the fore- and hind-feet show wide range of variations and modifications as they play very important roles in the process of jumping, climbing and digging which suit their habitats and their mode of life. The skeletal elements of the hand and foot exhibit several features reflecting the specialized methods of locomotion, and are related to the remarkable adaptations. Locomotion is a fundamental skill for animals. The animals of the present studies can take various forms including swimming, walking as well as some more idiosyncratic gaits such as hopping and burrowing. Key words: Lizards, osteology, limbs, locomotion. INTRODUCTION In vertebrates, the appendicular skeleton provides (Robinson, 1975).

Instead, we examine the rate of production (productivity of Biological Sciences, University of Reading, hereafter) calculated as the total mass of offspring produced in a year. We test ReadingRG6 6AS, UK whether productivity is influenced by proxies of adult mortality rates such as insularity and fossorial habits, by measures of temperature such as environmental and body temperatures, mode of reproduction and activity times, and by environ- mental productivity and diet. We further examine whether low productivity is linked to high extinction risk. Location World-wide. Methods We assembled a database containing 551 lizard species, their phyloge- netic relationships and multiple life history and ecological variables from the lit- erature. We use phylogenetically informed statistical models to estimate the factors related to lizard productivity. Results Some, but not all, predictions of metabolic and life-history theories are supported. When analysed separately, clutch size, relative clutch mass and brood frequency are poorly correlated with body mass, but their product – productivity – is well correlated with mass. The allometry of productivity scales similarly to metabolic rate, suggesting that a constant fraction of assimilated energy is allocated to production irrespective of body size.

In this study a total number of 11 specimens of Mediodactylus ilamensis were collected from type locality (Zarin-Abad) as well as a new locality in Dinar- Kooh Preserved area, Abdanan Township approximately 27 km on an aerial line in the east of type locality. To investigate morphological variation and reveal sexual dimorphism we employed 32 metric and meristic characters. The most important morphological characteristics of this species are as follow: all scales of the body, with the exception of intermaxillaries, nasals, chin shields, and upper and lower labials, strongly keeled; postmentals absent, dorsal crossbars broad and equal to, or wider than, interspaces; scales of frontal and supraocular regions toward snout are multi-keeled (in some scales up to six keels) and polyhedral. Of the studied morphological characters only two are different significantly between males and females: number of active precloacal pores and ear diameter (vertical).

Important nomenclatural actions pro- posed include the designation of a lectotype for the nomen Stenodactylus guttatus ensuring continuity of the prevailing usage of S. petrii, and the proposal of maintaining prevailing usage of Stenodactylus sthenodactylus by applying to the International Commission of Zoological Nomenclature to set aside the existing name-bearing type and replace it with a neotype corresponding with that usage. Key words: Reptiles, Gekkonidae, Stenodactylus, North Africa, taxonomy, lectotype, neotype Introduction The gekkonid genus Stenodactylus Fitzinger, 1826 comprises 12 currently recognized species distributed across Northern Africa, Arabia and the Middle East, extending around the Arabian Gulf to coastal southwestern Iran (Arnold 1977, 1980; Metallinou et al.
