ENGLISH ABSTRACT: This study investigates the phylogeographic structure of three co-distributed forest-living reptile species, the Pondo flat gecko (Afroedura pondolia), the forest thread snake (Leptotyphlops sylvicolus) and the Natal black snake (Macrelaps microlepidotus), by sampling specimens from the Eastern Cape and KwaZulu-Natal provinces of South Africa. Phylogenetic results, using Bayesian inferences and maximum likelihood, from the combined mitochondrial sequence data (ND4 and cyt b), along with population genetic analyses suggest the presence of broadly congruent biogeographic breaks among the study taxa. Sequence divergence values suggest that A. pondolia and L. sylvicolus represent species complexes comprising several cryptic species while M. microlepidotus exhibits population level differentiation. Divergence-time estimates indicate that cladogenesis within the study taxa occurred during the late Miocene to the Plio/Pleistocene climatic shifts, suggesting that cladogenesis was driven by climatic oscillations and suitable habitat fragmentation. We further investigate the species level divergence within A. pondolia and L. sylvicolus by including two partial nuclear loci (PRLR and RAG1) and employing several species delimitation methods (ABGD, bGMYC, PTP and STACEY). The species delimitation results were generally incongruent, estimating between two and 14 species nested within A. pondolia and between ten and 12 species nested within L. sylvicolus. In both taxa, the species hypotheses retrieved by STACEY based on the total-evidence data were preferred and used to define groups in the morphological analyses. In A. pondolia the multivariate morphological analyses indicate statistically significant differences among the four putative species, corroborating the presence of four species. In L. sylvicolus the morphological analyses exhibit large overlap among the ten putative species but indicate differences between grassland and forest species. The narrow distributions of the putative species identified in the present study have further implications for the conservation status of A. pondolia and L. sylvicolus and suggest that the fragmented forest habitat along the east coast of South Africa may harbor significantly higher levels of diversity than currently recognized.

▼ Thirty-three wild Victorian lace monitors, (Varanus varius), of unknown age and sex, were captured by noose pole or aluminium box trap from Cape Conran in East Gippsland, Victoria, Australia. In addition to establishing reference ranges for blood parameters, it was further examined whether such values were influenced by the expected differences in habitat food resource availability and by body size and body condition. The packed cell volume (PCV) for the lace monitors was 21-43.6%. Lymphocytes were the most common leukocyte. The haemoparasite Hepatozoon varanicola was found in all 33 blood samples. There was a significant difference in the serum glucose concentrations between the two methods of capture (higher concentration in box-trapped animals) presumably due to a physiological response to capture stress. The results of this study may be used as a basis for evaluation of health in lace monitors. Between January 2007 and June 2008 a total of 504 reptiles comprising four families and 57 species were sampled for the presence of Salmonella by cloacal or intestinal swabbing. Salmonella was identified in 139 (27.6%) of the 504 animals tested. Of the 504 reptiles examined, 210 were captive animals and 294 were wild specimens. Ninety-eight (46.8%) of the captive reptiles were found to be shedding Salmonella at the time of sampling. In contrast, only 41 (13.9%) of the wild reptiles were Salmonella positive. The prevalence of Salmonella was significantly higher in captive reptiles (P < 0.0001). Salmonella were not cultured from any of 60 wild freshwater chelonians or 48 wild southern water skinks (Eulamprus heatwolei). In general, snakes had the highest prevalence of Salmonella carriage with 72/104 (69.2%) animals shedding, lizards had an intermediate prevalence, with 65/299 (27.1%) individuals shedding and chelonians had the lowest prevalence with 2/101 (2%) animals shedding. It was also discovered that animals from Healesville Sanctuary were significantly more likely to be shedding Salmonella than reptiles from private collections (P = 0.001) and that Healesville Sanctuary reptile house animals were much more likely to shed Salmonella than animals that reside elsewhere in the park (P < 0.0001). Salmonella enterica subsp. enterica was more frequently identified in wild reptiles than captive reptiles (P = 0.033) and Salmonella enterica subsp. diarizonae was more frequently identified in captive reptiles than wild reptiles (P = 0.001). The results of this investigation suggest that wild reptiles in Australia are much less frequently carriers of Salmonella than captive reptiles and that diet and captivity may influence Salmonella excretion.

▼

During the· evolution of diapsids, the tarsus underwent considerable structural change. An analysis of the mechanics of each kind of tarsus based on x-ray studies of locomotion and studies of the structure of the pelvic limb in extant diapsids indicates that the early structural changes are related to the development of an intratarsal joint and consolidation of the metatarsus. Primitively, warping of the distal tarsal row was an integral part of the functioning of the tarsus. Key changes in the origin of the lizard tarsus were changes in the joints that eliminated the need for this movement of the distal tarsals. This was probably followed directly by the hooking of the fifth metatarsal and consolidation of the metatarsus. A distinctive type of tarsus is seen in the earliest rhynchosaurid Noteosuchus, the protorosaurian reptiles, the earliest archosaur Proterosuchus and in Trilophosaurus. This kind of tarsus is a suitable structural ancestor to the tarsus of advanced rhynchosaurids, archosaurs and possible sphenodontids. [...]

Pendant l'évolution des reptiles diapsides, le tarse s'est changé considérablement. Une analyse des mécaniques de chaque genre de tarse, fondée sur des études radiographiques de la locomotion et des études de la structure du membre postérieur des reptiles diapsides extants indiquent que les changements structuraux initiaux sont relatifs à l'évolution d'une articulation intertarsienne et au raffermissement de détatarse. La déformation primitive de la rangée tarsalienne faisait une partie intégrale du fonctionnement du tarse. Les changements importants dans l'origine du tarse du lézard étaient des changements de l'articulation qui ont éliminé la nécessite de ce mouvement des tarsaliens. C'était probablement suivi immédiatement par l'agrippement du cinquième métatarsien et la raffermissent du métatarse. Un type distinctif du tarse est observé dans le rhynchosaurien le plus primitif, Noteosuchus, les reptiles proterosauriens, l'archosaurien les plus primitifs, Proterosuchus, et dans Trilophosaurus. Ce genre de tarse est un ancêtre structural convenable au tarse des rhynchosauriens, des archosauriens et peut-être bien des sphenodontiens plus avances. [...]

▼ La resistencia antimicrobiana es un fenómeno de gran importancia a nivel mundial, debido a sus consecuencias en la salud tanto humana como animal y también por las consecuencias económicas que genera. Entre las bacterias que presentan multirresistencia se encuentra Salmonella spp., patógeno distribuido mundialmente, generalmente transmitido por los alimentos, pero también por contacto directo o indirecto con su reservorios animales. Dentro de estos, adquieren relevancia los reptiles por ser portadores asintomáticos de la bacteria, constituyendo un reservorio que cada vez adquiere mayor importancia debido a la creciente popularidad que presentan como mascota en las familias actuales. En Chile existen escasos estudios sobre resistencia antimicrobiana en cepas de Salmonella spp. aisladas de reptiles que asocien genes a la resistencia fenotípica, razón por la cual, el objetivo del presente estudio apunta a la detección de genes de resistencia antimicrobiana en cepas de Salmonella spp. aisladas de reptiles en cautiverio, en la Región Metropolitana en Chile. Para ello, se realizó una prueba de susceptibilidad antimicrobiana por el método de Kirby-Bauer y posteriormente, mediante la técnica de PCR, se buscaron 11 genes de resistencia en las cepas en análisis, independiente de su fenotipo. Dentro de los genes a detectar, 3 de ellos están asociados a resistencia a beta-lactámicos (blaTEM, blaOXA y blaPSE-1), 4 a resistencia frente a estreptomicina (aadA1, aadA2, strA y strB), 3 para resistencia a tetraciclinas (tet(A), tet(B), tet(C)) y un gen que confiere resistencia a cloranfenicol (cmlA). Se observó una elevada sensibilidad fenotípica, donde el 23,5% de las cepas fue resistente a estreptomicina. De las 34 cepas analizadas, sólo se detectó el gen blaTEM en un 61,7%. El resto de las cepas resultaron negativas a la detección de los otros genes en análisis. La alta sensibilidad detectada puede deberse a fenómenos de curación plasmidial, mutaciones cromosomales, regulación de la expresión génica, entre otros, como mecanismo de restauración del fitness bacteriano en cepas conservadas en un medio carente de presión selectiva. Se concluye que las cepas analizadas presentan elevada sensibilidad fenotípica frente a beta-lactámicos, tetraciclinas, cloranfenicol y estreptomicina, encontrando sólo cepas portadoras del gen blaTEM.; Antimicrobial resistance is a phenomenon of great importance worldwide because of its impact on both human and animal health and the economic consequences it generates. Among resistant bacteria is Salmonella spp., worldwide distributed pathogen, usually transmitted by food, but also by direct or indirect contact with animal reservoirs. Within these, reptile become relevant because they are asymptomatic carriers of the bacteria, forming a reservoir that increasingly becomes more important due to the growing popularity as pets in today's families. In Chile there are few studies on antimicrobial resistance in strains of Salmonella spp. isolated from reptiles that associated genes to phenotypic resistance,…

▼ Las especies invasoras son actualmente la segunda mayor amenaza para la biodiversidad siendo un componente generalizado y significativo del cambio ambiental global causado por los seres humanos. Si bien durante las últimas décadas se describe una declinación de las poblaciones de reptiles y anfibios a nivel mundial, son cada vez más los registros de especies de estos grupos que se desplazan a nuevos hábitats muchas veces generando efectos negativos sobre estos ambientes. Tarentola mauritanica o salamanqueja común, es una especie de reptil que ha sido reportada como introducida en diferentes países incluyendo Chile, donde al parecer de manera accidental se transportaron individuos junto con materiales importados para el Metro de Santiago. Con el fin de confirmar molecularmente la presencia de esta especie, determinar su origen y describir su fauna parasitaria, en el presente estudio se capturó a individuos de la población encontrada en la ex Ciudad de Niño en la comuna de San Miguel, Región Metropolitana. Mediante la secuenciación de un segmento de 12S y 16S ARNr fue posible confirmar que Tarentola mauritanica mauritanica es la especie introducida en nuestro país. Asimismo, utilizando secuencias obtenidas de congéneres desde diferentes zonas de su distribución natural, se realizaron análisis filogenéticos para determinar la procedencia de este reptil. Dada la baja diversidad genética mitocondrial descrita para esta especie en el clado europeo, no fue posible obtener esta información. Finalmente, se observó que los individuos capturados presentaron menor diversidad y densidad parasitaria que lo descrito para la especie en su distribución natural, lo cual concuerda con lo reportado para diferentes especies introducidas a nivel mundial; Nowadays invasive alien species are considered the second major threat to biodiversity and a significant component of the global environmental change induced by human population. Even though it has been described a declination of reptile and amphibian populations worldwide there is an increasing amount of reports from these animals moving to new habitats causing negative effects over the colonized environments. Tarentola mauritanica (Moorish Gecko) is a reptile that has been reported as introduced in different countries around the world. Apparently, they arrived to Chile traveling together with imported materials for the Subway (Metro de Santiago). The aim of the present study was to confirm using molecular methods the presence of T. mauritanica in Chile, to determinate its origin and to describe its parasites. The samples were taken from the gecko population located in ex Ciudad de Niño (Comuna de San Miguel, Región Metropolitana, Chile). Sequencing fragments from 12S and 16S rRNA it was confirmed that Tarentola mauritanica mauritanica is the alien introduced species in our country. Likewise, phylogenetic analysis were conducted comparing the obtained sequences with others from individuals within their natural distribution to determine the origin of this population. Nevertheless, it…

▼ The evolution of snakes (Squamata: Serpentes) represents a major transition in squamate reptiles and involves extensive modifications in the body plan. Functional morphology and phylogeny are integrated to discuss adaptive morphological traits in the origin of snakes and in the evolution of the venom-injecting apparatus among lizards, which is convergent with that in snakes. The focus of these analyses is to determine how to best optimize morphological traits on the phylogeny and to use character distribution in terminal taxa to estimate ecological adaptation in ancestral nodes. To study the locomotion transition from lizards to snakes, 45 virtual models of the squamate bony labyrinth in the inner ear were reconstructed. The results show morphological diversifications of the vestibular region among burrowers, generalists and marine swimmers. The vestibule is enlarged in fossorial species, and reduced in marine snakes and the marine lizard Platecarpus coryphaeus. To quantify the morphological differences and provide tractable methods to reconstruct locomotion in ancestral snakes, I performed three-dimensional geometric morphometric analysis of the 45 samples, using six landmarks and 22 semilandmarks. ANOVA tests on the Procrustes coordinates supported differences among fossorial, generalist, and aquatic locomotion categories. Phylogenetic signal was insignificant in the Procrustes coordinates. Using a phylogeny with the 44 extant samples as terminal taxa, I reconstructed shape coordinates of all internal nodes. Reconstructed shape of the vestibular region of key ancestral nodes in snakes preferred a terrestrial origin for crown-group snakes. Morphological proxies used in this study can be applied to stem snakes to estimate locomotion. Methodologically, this study provides a novel approach to resolve the question whether snakes become limbless on land or in the oceans. Evolution of the venom-injection apparatus in lizards is discussed, based on new material of Estesia mongoliensis. A total-evidence phylogenetic analysis of anguimorph lizards is performed with 86 anguimorph taxa coded to 435 morphological characters and four genes. The matrix includes eight new morphological characters. The total-evidence phylogeny suggests that Estesia Mongoliensis is a basal monstersaur whose crown groups are Heloderma, the only living venomous lizards. Presence of tooth flanges with venom grooves is recognized as a new monstersaurian synapomorphy in this study. Estesia mongoliensis has venom grooves comparable to extant Heloderma, but has a deeper root-to-tip groove in the caudal tooth carina, revealing morphological variations of lizard venom delivery apparatus that are not recorded in extant species.

▼ A popularidade dos rÃpteis em cativeiro tem aumentado nos Ãltimos anos, principalmente como animais de estimaÃÃo. Diversas espÃcies de microrganismos tÃm sido isoladas desses animais, os quais podem atuar como carreadores e disseminadores de importantes patÃgenos humanos, mas pouco se conhece sobre a sua microbiota fÃngica. Diante disso, o objetivo deste trabalho foi realizar o isolamento de espÃcies de Candida em amostras clÃnicas obtidas de jabutis (Chelonoidis spp.) e tartarugas marinhas (Chelonia mydas, Caretta caretta, Lepidochelys olivacea, Eretmochely imbricata), bem como avaliar a sensibilidade aos antifÃngicos de uso clÃnico e os seus fatores de virulÃncia. Para tanto, foi colhido material da cavidade oral e da cloaca de 77 animais, com auxÃlio de swabs, sendo 120 amostras de jabutis (n=60) e 34 amostras de tartarugas marinhas (n=17). O isolamento das cepas foi feito em Ãgar Sabouraud dextrose 2% com cloranfenicol e a identificaÃÃo foi realizada, posteriormente, atravÃs de mÃtodos morfolÃgicos e bioquÃmicos. A capacidade de cepas de Candida spp. secretar fosfolipases e proteases tambÃm foi testado, atravÃs da cultura em Ãgar gema de ovo e meio base para teste de protease, respectivamente. Um total de 12 cepas foi obtido de tartarugas marinhas, as quais foram identificadas como pertencentes Ãs espÃcies C. parapsilosis (n=4), C. guilliermondii (n=4), C. tropicalis (n=2), C. albicans (n=1) e C. intermedia (n=1). Quanto aos jabutis, foram isoladas 66 cepas de C. tropicalis (n=27), C. famata (n=27), C. albicans (n=7), C. guilliermondii (n=4) e C. intermedia (n=1). ApÃs a identificaÃÃo, as cepas foram submetidas ao teste de sensibilidade atravÃs do mÃtodo de microdiluiÃÃo em caldo, segundo o documento M27-A3, ante aos antifÃngicos anfotericina B, itraconazol e fluconazol. As concentraÃÃes inibitÃrias mÃnimas para anfotericina B, itraconazol e fluconazol variaram de 0,03125-0,5 μg/mL, 0,03125->16 μg/mL e 0,125->64 μg/mL, respectivamente. Ao todo, obtiveram-se 19 cepas resistentes aos derivados azÃlicos (14 cepas de C. tropicalis e 5 cepas de C. albicans). Quanto Ã produÃÃo de proteases, 11% das cepas secretaram estas enzimas. Por fim, somente 5% das cepas produziram fosfolipases. Desta forma, o presente estudo sugere que esses animais sÃo carreadores de Candida spp. resistentes a derivados azÃlicos e produtoras de fatores de virulÃncia, podendo atuar como fonte de infecÃÃo para humanos e outros animais Advisors/Committee Members: Ãrika Helena Salles de Brito, Maria Fatima da Silva Teixeira, Raimunda SÃmia Nogueira Brilhante.

▼ A herpetofauna do Cerrado foi investigada ao longo de extensa área da bacia do rio Tocantins de três formas distintas e complementares. Primeiro, uma amostragem rápida realizada em 11 áreas situadas entre o Planalto Central em Goiás e o norte da depressão do Tocantins na divisa dos estados de Tocantins e Maranhão obteve dados menos completos, porém em toda a extensão estudada. Segundo, na parte central da área a UHE LEM, foi intensamente amostrada, obtendo-se uma lista completa de espécies para a área e dados sobre sua distribuição na paisagem. As informações reunidas também permitiram identificar alguns dos impactos causados pelo empreendimento. Terceiro, nesta área, seis pontos foram amostrados bimestralmente ao longo de três anos, permitindo obter informações mais finas sobre o efeito do habitat, da sazonalidade e do deslocamento da fauna pelo enchimento do reservatório nas assembléias de anuros e lagartos. Os dendrogramas construídos com índices de similaridade de Jaccard entre áreas do Cerrado e de outras paisagens neotropicais adjacentes relativamente bem amostradas indica que a fauna de serpentes, lagartos e anuros do Cerrado forma um grupo em relação outras paisagens, subdivido em dois grupos. Um deles está asssociado às depressões de baixa altitude, o outro aos planaltos centrais ou meridionais. No norte do Cerrado a riqueza de espécies é maior, ocorrendo espécies compartilhadas com a Amazônia ou com a Caatinga. No sul, ocorrem espécies com distribuição meridional. O número de espécies geralmente aumenta das áreas meridionais mais áridas para as áreas mais chuvosas próximas ao Equador. Os grupos aquáticos, fossoriais e arborícolas são especialmente mais diversos nas áreas equatoriais. O Cerrado da Depressão do Tocantins é, após as áreas Amazônicas, geralmente a área mais rica em espécies. Lagartos de alta temperatura corporal são mais freqüentes nos cerrados abertos situados nos interflúvios; espécies mais sensíveis a desidratação e de menor temperatura corporal ocorrem nas florestas de fundo de vale. No baixo curso dos rios, nas planícies aluviais e terraços registraram-se abundâncias elevadas de anuros de reprodução aquática, que usam habitats abertos ou florestados. Nas áreas de relevo mais encaixado das cabeceiras estes espécies são menos freqüentes. Os lagartos são menos afetados pelas sazonalidade climática que os anuros. Na estação chuvosa, especialmente em dezembro, ocorreram picos de freqüência de ocorrência, de atividade e maior riqueza de anuros. A reprodução e os nascimentos ocorrem concentrados na estação chuvosa na maioria das espécies, mas esta é especialmente mais concentrada nesta época nos anuros. A diferenciação filogenética dos nichos termo-hídricos das espécies de anuros e lagartos nas assembléias permite a partilha de recursos no tempo e no espaço. Os nichos termo-hídricos das espécies variam entre espécies com maior temperatura corporal e resistência elevada à desidratação e espécies com menor temperatura corporal e baixa resistência a desidratação. A organização espaço temporal das… Advisors/Committee Members: Rodrigues, Miguel Trefaut Urbano.

▼ Amphibian and reptile declines have been documented from across the globe in recent decades. This is a result of anthropogenically driven effects including transformation of the landscape, habitat destruction, environmental degradation, road mortality, leaching of chemicals and pollutants into the environment, genetic isolation and disease. More recently, several well-studied declines affecting snakes have been documented in the literature. Most studies emanate from North America and Europe, with a small percentage from Australia. Due to the absence of long-term site monitoring in Africa, the extent of snake population declines is mostly unknown and at best, speculative. My study aimed to provide baseline data on snakes from South Africa based on long-term field observation and accumulative data spanning a period of approximately 30 years, from 1988 – 2018. In my experience, I have noted perceived declines in several geographical regions, including species-specific declines. Whilst the primary focus of this study was on snakes, these declines extend to other amphibian and reptile species, and brief reference is made to these in the specific site studies. Firstly, in Chapter 1, I reviewed the published literature globally pertaining to snake conservation, population ecology and documented snake population declines and the contributing factors thereof. The causes of decline are complex and often interlinked, having a cascading effect. For example, a population of snakes isolated by roads and urban development will become genetically isolated, leading to weakened immunity and increased stresses, making them susceptible to disease and overloaded parasite burdens. Therefore, a population experiencing declines is affected by several interlinking causes. All contributing factors must be carefully analysed to initiate mitigation measures to prevent further decline. Secondly, in Chapter 2, I reviewed our current understanding of global snake diversity, conservation and systematics to quantify species diversity and conservation trends in extant snake species. We are far from understanding true snake species diversity with numerous new species being described by science annually. Systematics and taxonomy, including phylogenetic relatedness, are all crucial aspects required to facilitate and implement effective conservation measures if we are to conserve world snake diversity. Thirdly, in Chapter 3, I have presented snake data pertaining to road mortality based on a study undertaken along the R516 national road in Limpopo Province, South Africa. Road mortality has been identified as a contributing factor of snake population declines in many regions of the globe. The increasing network of roads and associated vehicular traffic is cause for concern, not only in protecting snakes, but other faunal species as well. In Chapters 4 and 5, I examined data from personal archived records taken at two different, well-defined, field study sites – one site situated in a former grassland habitat in Gauteng Province, which is now… Advisors/Committee Members: Downs, Colleen Thelma.

Veterinarska medicina - Mikrobiologija / Veterinary medicine - Microbiology

Salmonele predstavljaju veoma važne patogene mikroorganizme ljudi i životinja koji su odgovorni za 93,8 miliona infekcija i 155.000 smrtnih slučajeva ljudi godišnje u svetu. Uzročnik vedine slučajeva salmoneloze ljudi je hrana, ali su i brojne infekcije posledica direktnog ili indirektnog kontakta sa životinjama. Gmizavci predstavljaju značajni rezervoar velikog broja podvrsta i serovarijeteta Salmonella spp., a brojni radovi potvrđuju mogudnost prenošenja ovih bakterija sa gmizavaca na ljude. Cilj ove disertacije je bio da se ustanovi prisustvo i raširenost serovarijeteta Salmonella spp. i njihove rezistencije prema antimikrobnim sredstvima. Od aprila 2012. do aprila 2016. godine bakteriološki su ispitivani brisevi i feces 317 gmizavaca i vodozemaca, slobodnih u prirodi, držanih u zoološkom vrtu ili gajenih kao kudni ljubimci (152 kornjače, 76 guštera, 73 zmije i 16 žaba) poreklom od 42 različite vrste i izolovano je ukupno 57 sojeva Salmonella enterica (18,93%) od 301 gmizavca, za razliku od vodozemaca gde su svi uzorci bili negativni. Salmonella enterica je izolovana kod 24 kornjače (15,79%,), 14 guštera (18,42%) i 19 zmija (26,03%), a nakon serotipizacije 41 soj je identifikovan kao S. enterica subsp. enterica (I) i 16 kao S. enterica subsp. diarizonae (IIIb). Ukupno je serotipizacijom utvrđeno prisustvo 24 različita serovarijeteta Salmonella enterica, od kojih po prvi put u Srbiji 10 serovarijeteta, a jedan determinisani serovarijetet se ne nalazi u White-Kauffmann-Le Minor tabeli. Kod sojeva Salmonella nije utvrđena rezistencija prema ispitivanim antimikrobnim sredstvima. Salmonella Enteritidis, Salmonella Hadar i Salmonella Thompson koje su otkrivene kod gmizavaca spadaju u serovarijetete Salmonella koje dovode do infekcija ljudi. Dobijeni rezultati nedvosmisleno ukazuju da gmizavci, kako slobodni u prirodi tako i u zoološkom vrtu ili držani kao kudni ljubimci, mogu predstavljati rezervoar Salmonella spp., što je od velikog epidemiološkog značaja usled zoonoznog potencijala uzročnika. Otkrivanje retkih i egzotičnih serovarijeteta Salmonella spp. ukazuje na neophodnost sprovođenja daljih sveobuhvatnih istraživanja i sistematskog pristupa u razjašnjenju uloge gmizavaca u epidemiologiji salmoneloze.

▼ Many animals possess the remarkable ability to change colour, and this ability has several potential functions, including communication, social signalling, and camouflage. However, the functional significance and drivers of colour change are still poorly understood in many taxa. In this study, I applied laboratory and field approaches to examine an important, but understudied potential function of colour change in terrestrial ectotherms: thermoregulation. I quantified colour change in response to temperature in wild-caught bearded dragon lizards (Pogona vitticeps), which are known for their marked individual colour change and geographic colour variation. For comparison, I also quantified the extent of non temperature-dependent colour change from dark to light states elicited during social interactions and at different times of the day. I found that lizards showed substantial animal-visible (UV-Vis) and near infrared (NIR) skin reflectance change in response to temperature for dorsal but not ventral body regions. By contrast, lizards showed the greatest capacity for colour change on the ventral body regions under other (non temperature-dependent) circumstances. I then used biophysical models to predict the thermal benefit of colour change to a bearded dragon lizard, and found that in the morning, under environmental conditions characteristic of the field site during the breeding season, the maximum temperature-dependent change in dorsal reflectivity would result in a 9% increase in the rate of heating. Although this temperature-dependent colour change may therefore aid thermoregulation, colour change is likely to be less important as a mechanism for bearded dragons to thermoregulate than other mechanisms such as behavioural changes in posture and shuttling between sun and shade. Therefore, colour change may have primarily evolved to enhance social signalling or camouflage, but subsequently been co-opted for thermoregulation. To further understand the relative importance of the different functions of colour change to a bearded dragon in the wild, and how they accommodate these functions when they conflict, I quantified colour change in 11 free-ranging bearded dragons (Pogona vittceps) over an 8-week period during the breeding season (October 9th– November 28th, 2013). In addition to taking daily snapshots of multiple lizards over the entire field study, I followed a single lizard through an entire day (‘day in the life’), and modelled the effect of different thermoregulatory behaviours on core body temperature. From this, I found that lizards showed a significant and consistent relationship between their dorsal skin coloration and both background coloration and either core body temperature or skin temperature. However, background colour explained the most variation in lizard colour, and there was no evidence that these lizards exhibit temperature-dependent background choice. Furthermore, the focal lizard that was followed through the entire day behaved very similarly to a predicted modelled “thermoregulating” lizard,…

▼ Biodiversity loss is the most critical environmental problem threatening ecosystem, animal, and human health today. Increases in extinction rates have been observed over the past 50 years, with reptile losses occurring twelve times faster than traditional extinction rates. This demonstrated biodiversity loss is secondary to climate change, habitat destruction, infectious disease, invasive species, poaching, and unsustainable trade. Approximately 20% of all reptiles are threatened with extinction and population declines are approaching rates similar to the current amphibian extinction crisis. Preventing the extinction of reptiles will require humans to acknowledge these losses and develop plans to preserve these evolutionary sentinel species. Assisted reproductive technologies (ART) are well developed in a handful of species, and these technologies have become integral parts of conservation programs for threatened and endangered species. The creation of functional and sustainable reproductive assistance programs for reptiles using ART will strengthen our conservation capacity. Combining ART with an understanding of reproductive physiology will enable scientists to capture genetic material from different animals housed at different institutions, overcoming reproductive barriers. Subsequent gamete transport will reduce the need to transport animals from stressful or dangerous environments for breeding. Additionally, these gametes could be stored indefinitely to preserve genetic diversity. The goal of this research was to systematically apply ART to male reptiles. Semen was safely and successfully collected from veiled (Chamaeleo calyptratus) and panther chameleons (Furcifer pardalis) using electroejaculation. The annual reproductive cycles of these two chameleons were characterized under captive conditions, and both species follow season breeding cycles. Human chorionic gonadotropin can be used to increase circulating plasma testosterone concentrations in veiled chameleons. Short-term cooled semen storage can be done in red-eared sliders (Trachemys scripta elegans) and diamondback water snakes (Nerodia fasciata) using Ham’s F10, INRA 96, and sperm washing buffer; green anole (Anolis carolinensis) semen could not be stored using these same extenders. Red-eared slider turtle spermatozoa motility was lost following cryopreservation, but plasma membrane integrity remained. Reptile survival is dependent on how we plan today. ART will help us develop programs to preserve the genetics of these sentinel animals.

▼ Las mascotas exóticas, especialmente los reptiles -ampliamente distribuidos por el mundo representan un alto riesgo para la Salud Pública, debido principalmente a su condición de portadores intestinales de Salmonella spp., estimándose que del total de casos de salmonelosis un 7% se asocia al contacto con reptiles (SAR). Del total de SAR un 15% aproximadamente presenta un cuadro invasivo, los cuales incluyen septicemia, meningitis, infección en cartílagos e inclusive la muerte. La invasividad de Salmonella se encuentra asociada a genes de virulencia, que se organizan principalmente en la isla de Patogenicidad 2 (SPI-2) de su genoma. En consideración a lo anterior el propósito de este estudio fue detectar genes de virulencia asociados a invasividad, en cepas de Salmonella spp. aisladas desde reptiles en cautiverio de la Región Metropolitana. En este estudio se seleccionaron cuatro genes de virulencia (spiA, sseG, ssaB, sscB) asociados a invasividad, específicamente a la sobrevivencia de esta bacteria al interior de macrófagos y su diseminación sistémica. De las 34 cepas analizadas, el perfil más frecuente encontrado fue spiA/sscB/sseG (35,2%), seguido por sscB/sseG/ssaB (8,8%), siendo los genes mayormente detectados sseG (91%), ssaB (71%) y sscB (61%), mientras que el gen spiA fue menor su detección (31%). Estos resultados constituyen la primera aproximación molecular de la potencial virulencia de cepas de Salmonella aislada desde reptiles en Chile. Se discuten los resultados con la variabilidad genética en cepas de diferentes fuentes animales y el hombre.; Exotic pets, especially reptiles, are widely distributed throughout the world, particularly in Chile, where a high percentage are intestinal carriers of Salmonella spp. (About 50%), representing a risk to public health. Thus, it is estimated that of all cases of salmonellosis in humans, about 6-7% is associated with contact with reptiles (RAS). Of total RAS, about 15% has a box-invasive, which include septicemia, meningitis, infection in cartilage and even death. Salmonella invasiveness is encoded in virulence genes that are organized primarily in Pathogenicity Island 2 (SPI-2). The purpose of this study was to detect genes associated with invasiveness virulence in Salmonella strains, isolated from reptiles in captivity in the Metropolitan Region. In this study, four virulence genes (spiA, sseG, ssaB, sscB) associated with invasiveness, and therefore, belonging to the pathogenicity island 2 were selected. These genes are related to the survival of the bacteria within macrophages and their systemic dissemination. Of the 34 strains tested, the most common profile was spiA/ sscB/ sseG (35.2%), followed by sscB/sseG/ssaB (8.8%), the most prevalent genes sseG (91%), ssaB (71%) and sscB (61%), while the spiA obtained a lower prevalence (31%). These results provide the first molecular approach of potential virulence of Salmonella strains isolated from reptiles in Chile. The results with the genetic viability in different strains of animals and humans sources are…

▼ The cephalic scale sensilla are mechanoreceptors poorly studied in snakes; therefore, their role as sensory system for snakes is still unknown. There is a lot of variance in the density and distribution of the sensilla on each cephalic scale, then, we hypothesize that these variations could support the evolutionary relationships in some species of the subfamily Dipsadinae. To test this hypothesis, we used 10 individuals from seven species, six from the subfamily Dipsadinae and one from the subfamily Colubrinae (outgroup). The evolutionary relationships between these species were obtained from a phylogenetic tree, constructed with sequences of the gen Cytochrome b obtained from NCBI. For the density and distribution of the sensilla, the outer layer of keratin was removed from four cephalic scales: parietal, genial, supralabial and infralabial. Later, we used optical microscopy and heatmaps to quantified and illustrate the distribution of sensilla on the scales. In addition, the density of the sensilla on each scale was correlated with the total length of the snakes. Finally, using this data, we established the phylogenetic signal through the statistical tests Blomberg's K and Pagel's. Results show three different general distributions of the sensilla on the scales: around the borders, a homogeny distribution and forming groups in one border. We found also a negative correlation between the length of the snakes and the density of sensilla on some of the scales in three of the species. In addition, the use of the sensilla as a tool to establish evolutionary relationships showed that only the genial scale has a phylogenetic signal according to both tests; and supralabial and infralabial scales only with the Blomberg's K test. Finally, according to our results is possible to conclude that the density of the sensilla on the genial scale has a phylogenetic signal, and it is a morphological trait that supports the molecular phylogeny of the subfamily Dipsadinae Advisors/Committee Members: Molina Escobar, Jorge Alberto, director/asesor.

Stratigraphic and fossil evidence indicates that these animals, like their modern counterparts, were able to coexist in the same environment for over ~50 million years from the Early Jurassic (~180 million years ago) to the Early Cretaceous (~130 million years ago). Marine reptile ecosystems were often very diverse, and included animals from different lineages, of disparate body-size and inferred ecology living alongside each other in the same environment. This unusual diversity suggests that marine reptiles formed complex ecosystems, and may have occupied analogous ecological roles today held by large fish, sharks, crocodiles, sirenians, and cetaceans. However, these comparisons are essentially qualitative, as they are based on the recurring convergent morphologies of skulls, mandibles and dentitions in aquatic tetrapods. Yet, they have never been quantitatively tested. Furthermore, although we have a comprehensive understanding of the anatomy, systematics, phylogenetic relationships, physiology and feeding ecology of these extinct animals, little is still known about the structure and evolution of their ecosystems. Thus, we do not understand what enabled marine reptiles to form complex assemblages, how their fauna changed through time, and more importantly how climatic and environmental changes shaped their long-term evolution. Answering these questions is essential because understanding past marine ecosystems may inform on whether and how modern ones can adjust to changes in the ocean temperature, chemistry and sea-level. In order to establish the reliability of these comparisons, in this project, I consider the evolution of the diverse marine reptile fossil assemblage of the Jurassic Sub-Boreal Seaway (JSBS) of the UK. The fossil record of the JSBS is an ideal case-study for many reasons. Firstly, it is a well-documented, high-diversity ecosystem, represented by hundreds of well-preserved specimens collected from the world-famous Oxford Clay Formations (OCF Callovian-early Oxfordian, late Middle to early Late Jurassic) and Kimmeridge Clay Formation (KCF - Kimmeridgian to Tithonian, Late Jurassic). These specimens have been intensively collected since the XIX century, and are available in museum collections. Secondly, the fossil record of the JSBS covers a continuous interval of ~18 million years (middle Callovian-early Tithonian ~166-148 million years ago) of marine reptile evolution, in a single seaway, during a time of well-documented environmental changes. These changes in sea-level, temperature and chemistry happened in concert with drastic changes in the composition between the OCF and KCF marine reptile faunas across the Middle-Late Jurassic boundary. Unfortunately, to date, the attempts to understand whether there is a correlation between these events have been hampered by the scarcity of fossils material from the intermediate…

Le développement des activités industrielles et agricoles du siècle dernier a eu pour conséquence le rejet de substances chimiques dans l’environnement, qui contaminent les écosystèmes, et peuvent s’accumuler dans les plantes, les sédiments, et le long des chaînes alimentaires. Il apparait primordial d’effectuer une évaluation du risque écologique associé à la présence de ces composés dans les milieux naturels et les espèces sentinelles sont des outils judicieux pour déterminer l’exposition des individus et évaluer les conséquences sur les organismes. Les amphibiens et les reptiles possèdent des caractéristiques écologiques et biologiques qui les rendent potentiellement intéressants en tant qu’espèces sentinelles. L’objectif des études présentées dans cette thèse est de déterminer la disponibilité de certaines substances dans l’environnement, et d’évaluer les effets de la contamination environnementale sur les organismes en utilisant plusieurs espèces de reptiles et d’amphibiens, (i) en mesurant les niveaux de polluants accumulés dans les tissus d’espèces de reptiles ; (ii) en évaluant l’influence d’un habitat contaminé sur la morphologie d’adultes de crapaud commun (Bufo bufo) ; (iii) en mesurant de manière expérimentale l’impact d’une molécule fréquemment retrouvée dans l’environnement sur le développement de têtards de crapaud commun. Nos résultats montrent d’une part que les reptiles accumulent efficacement les polluants organiques et les éléments traces métalliques dans leurs tissus, et permettent d’évaluer efficacement la contamination globale d’une zone, mais aussi de mettre en évidence des pollutions ponctuelles localisées. D’autre part, nos travaux montrent une influence de l’habitat agricole sur la morphologie du crapaud commun, potentiellement causé par la présence de contaminants dans ces milieux. Enfin, nous avons pu mettre en évidence un effet de concentrations faibles d’AMPA, métabolite principal du glyphosate, sur le développement de têtards de crapaud commun. Les amphibiens constituent donc des organismes efficaces pour étudier l’impact de la contamination de l’environnement sur les caractéristiques individuelles. Nos travaux montrent ainsi l’utilité de certaines espèces de reptiles et d’amphibiens comme espèces sentinelles de la présence de contaminants dans l’environnement et de leur impact potentiel sur les organismes. Les travaux en écotoxicologie qui portent sur ces organismes restent trop rares, et il est impératif de développer la recherche dans ce domaine, pour participer de manière efficace à l’évaluation du risque environnemental.

The development of industrial and agricultural activities over the last century has resulted in the release of chemicals into the environment, which contaminate ecosystems and can accumulate in plants, sediments and across food webs. As such, it is essential to conduct an assessment of the ecological risk associated with the presence of these compounds in natural environments. Achieving this can be aided through the study of sentinel species, which can be used…

Au cours des dernières décennies, d'énormes quantités de haies, de lisières ont étédétruites en Europe tandis que le régime des incendies majeurs augmente dans les milieuxméditerranéens. La perte de ces milieux de type lisières s'accompagne d'une chutecatastrophique de la biodiversité. Notamment par la perte des refuges disponibles pour lafaune. Cette thèse s'intéresse à l'importance des abris à différentes échelles et sur différentsmodèles biologiques. Premièrement, l'influence de la disponibilité en abris au pied des haiessur la biodiversité a été démontrée à l'aide d'inventaires et grâce à une expérimentation surle terrain. Pour cela, une nouvelle approche d'inventaire qui combine les avantages desinventaires rapides et des techniques non létales a été mise au point. A une échelleintermédiaire, l'impact positif de l'ouverture du milieu forestier sur des populations dereptiles a été mis en évidence. Enfin, un suivi au niveau individuel de tortues d'Hermann apermis de suivre les conséquences de modifications l'habitat suite à un incendie majeur ; ilsuggère que les habitats brûlés restent favorables sur le long terme.En conclusion, l'importance des abris pour la biodiversité a été démontrée à plusieurséchelles d'espace, de temps et de précision. La conséquence pratique est que les fichestechniques de gestion des haies et des lisières devraient en tenir compte, ce qui n'est pas lecas actuellement.

During the last decencies, massive amounts of hedgerows and forest hedges have beendestroyed in Europe whereas increasing fire regimes threatened Mediterranean habitats.The loss of these hedge habitats is concomitant to a drastic loss of biodiversity. Notablythrough the decrease of shelter available to the fauna. This thesis aims to investigate therole of refuges considering different scales and biological systems. First, the positiveinfluence of the availability of shelter at the base of hedgerows on biodiversity has beendemonstrated using surveys and a field experiment. For that, a novel technique has beendeveloped by combining the advantages of rapid biodiversity assessments with non-lethalprocedures. At an intermediary scale, the positive impact of habitat opening on ophidianpopulations has been shown in a forest context. Finally, individual monitoring of Hermanntortoises allowed us to examine the impact of a major fire in habitat changes; the resultssuggest that burnt habitats remain suitable on the long term.In conclusion, the importance of refuges on biodiversity have been demonstrated atdifferent time, spatial and accuracy scales. In practice, technical recommendations shouldtake into account this key element to manage hedgerows and other hedge habitats; thiscurrently not the case.

▼ Phenetic relationships among populations of the mud turtles ofthe Kinosternon scorpioides and K.. leucostomum complexes in Mexico andCentral America were examined using multivariate statisticaltechniques.Thirty-one mensural and five qualitative characters were measuredon the external surfaces of 3,062 adults of the two species complexes.The geographic ranges of the species complexes were divided by riverdrainage into populations for statistical analyses. Fifty-eight populationswere defined for the K. scorpioides complex, and 22 for J<.leucostomum.Each complete statistical analysis included a multiple discriminantanalysis, a canonical analysis, and a phenetic distance (D2 )analysis. Six complete analyses were run, one each on males and femalesof: (1) j<. integrum and its closest relatives; (2) K.scorpioides; and (3) J<. leucostomum. Mensural data were standardizedfor size by dividing each character by carapace length; a comparisonof ratio vs. regression standardization in K. leucostomum analyses revealedno statistically significant differences in the resultsobtained.Characters selected by the discriminant analyses and their functionalsignificance are discussed. A highly intercorrelated charactercomplex is described which suggests relatively high, wide carapacestend to be associated with extensive plastrons. It is hypothesizedthat this character complex is a terrestrial adaptation associatedwith seasonal aquatic environments; a test using a multiple regressionanalysis of environmental variables against relative plastralarea confirms the hypothesis.Females of all taxa tend to have more globular shells, more extensiveplastrons, and less emarginate anal notches than males.Canonical and distance analyses suggest that K. integrum isclosely related but phenetically distinct from two undescribed speciesfrom Sonora and Sinaloa, and Oaxaca, Mexico. A population from theRio Purificacion in coastal Jalisco is phenetically distinctive, butintegrum populations are otherwise relatively homogeneous.Kinosternon scorpioides consists of four phenetically distinctsubspecies in Mexico and Central America: (1) K. s^ cruentatum insouthern Mexico, Belize, and Guatemala; (2) K. ￡. abaxillare in theRio Grande de Chiapas; (3) K. alboqulare in most of Central Americaabove the Isthmus of Panama; and (4) K. s_. scorpioides on the Isthmusof Panama and northern South America.The Kinosternon leucostomum complex consists of one species, K.leucostomum, with two subspecies: (1) JK. 1_. 1 eucostomum in Atlanticdrainages of southern Mexico to eastern Nicaragua; and (2) K. JLpostinquinale in Atlantic and Pacific drainages from the Rio San Juanin Nicaragua, southward to northwestern South America.Lists of synonymies, diagnoses, and discussions of taxonomichistory are given for each taxon. Descriptions and discussions ofgeographic range and natural history are given for each species.The following are proposed as logical and parsimonious distributionalhistories.

L’étude de la composition isotopique de l’oxygène de l’émail des dents de vertébrésconstitue une méthode fiable de reconstitution des paléotempératures, grâce àl’interdépendance entre le δ18O de l’apatite des dents, le δ18O des fluides corporels, del’eau ingérée et la température du milieu. L’amélioration et la miniaturisation des techniquesanalytiques a permis d’augmenter la résolution du signal reconstitué, depuis les variations detempérature sur de grandes échelles de temps jusqu’aux variations saisonnières durant laformation de la dent. Cependant, ces variations du δ18O de la dent ne sont pas uniquementdépendantes des variations de température du milieu, mais peuvent également êtreaffectées par d’autres paramètres climatiques, comme la répartition des précipitations aucours de l’année, ou biologique, comme le mode de minéralisation de la dent, l’alimentation,la physiologie de l’animal ou des migrations.Les paramètres biologiques peuvent être estimés dans le cas de taxons possédantdes parents proches dans la faune actuelle. Par exemple, la connaissance des processus deformation et de minéralisation des dents de bovinés actuels permet d’interpréter le signalisotopique de l’oxygène enregistré dans les dents de bovinés fossiles. Ainsi, l’analyse dedents de Bison priscus provenant de l’aven de Coudoulous (Lot, France) a permis dereconstituer les variations saisonnières de température au cours de l’avant-dernier épisodeglaciaire (MIS 6) au Pléistocène moyen, lorsque la région servait de terrain de chasse àHomo neanderthalensis. Le climat était à cette époque plus froid de 4°C en moyenne, maisavec des saisons nettement plus contrastées. Ainsi, si les températures estivales étaientidentiques aux valeurs actuelles, les températures hivernales étaient plus basses de 6-7°C.En milieu marin, les variations saisonnières de température affectent uniquement leseaux de surface. Les plaques dentaires de myliobatidés, un groupe de raies pélagiquesvivant principalement entre 0 et 100 mètres de profondeur, sont un outil potentiel pourreconstituer la paléosaisonnalité. L’étude de plaques dentaires de Myliobatis et deRhinoptera actuels montre que la composition isotopique des dents de ces animauxenregistre des variations de température et de δ18O des eaux de surface. Ainsi, il est doncpossible de reconstituer les caractéristiques des masses d’eau traversées par l’animal. Cetoutil a également un intérêt paléoécologique car il permet de mettre en évidence d’éventuelscomportements migratoires, comme chez certains myliobatidés actuels. L’étude despécimens d’Aetomylaeus provenant du Pliocène de Montpellier (Hérault, France) montredes températures 5°C plus élevées par rapport aux v aleurs actuelles.
