Abstract: This report describes a clinical approach and observed behavioral and histologic changes in a pair of Timon lepidus treated with follitropin alfa to induce breeding. Hormonal treatments are very rarely used to treat infertility in reptiles; otherwise in other species as well as in human medicine they, as artifcial insemination, are one of the most important solutions. The conclusion of this case report suggests a possible therapy for this problem. A pair of 3-year-old ocellated lizards (Timon lepidus) was evaluated for mating reluctance. After hibernation, the male was introduced into the female’s cage. The female immediately showed aggresive behavior toward the male. This same procedure was successively tried without any positive results. After multiple failed attempts and about 1 month after the end of hibernation, we initiated therapy. We used follitropin alfa, a hormone identical to follicle-stimulating hormone (FSH), obtained by DNA recombination of ovarian cells of the Chinese hamster (Cricetulus griseus). Follitropin alfa often is used in human medicine in patients afficted by hypogonadism or insuffcient plasma levels of gonadotropins. By the eleventh day of treatment, the owner observed a behavior change that could be referred to as reproductive activity of the male. The female did not exhibit any aggressive behavior toward the male. Ten days after treatment, the owner reported the death of both specimens, due to a management mistake (i.e., both subjects were housed in the sun without shelter from excessive heat). Postmortem examination showed an increase in size of the gonads of both animals and no other organ alteration. In conclusion, in this clinical case it is possible that the increase in testicular activity and sexual segment of the kidney, could be due to the administration of FSH. As a result we can assert that, at least in the organs taken into consideration, there has not been found any toxicity, linked to the administration of gonadotropin in the short period. This case report could be used as a starting point for additional studies of mating in captive reptiles. References 1. Edwards TM, Gunderson MP, Milnes MR, Guillette, LJ.

The Mojave desert tortoise (Gopherus agassizii) is federally protected as threatened under the Endangered Spe- cies Act. Recently, numerous energy-development projects (primarily solar and wind) have gained approval to construct facilities in areas inhabited by desert tortoises. In an attempt to minimize the impact on desert tortoises, many projects propose to displace tortoises from the project sites and relocate them to other areas. Many steps must be taken to minimize the risks to the tortoises being moved, as well as to tortoises they might encounter after translocation from the project site. Among the many precautionary steps is assessing the health of tortoises at both the project and recipient sites, as well as at any reference sites as may be required for specifc projects. A standardized approach to health assessment data collection is necessary in order to monitor populations across projects and over temporal and spatial scales. In efforts to train biologists to perform consistent health assess- ments, sample collection, data collection, and reporting, the Health Assessment Training Class was developed. Students are trained on proper tortoise handling, biosecurity, anatomy and diseases, identifcation of abnormal clinical signs, body condition scoring, subcarapacial venipuncture and other sample collection, sample process- ing, and overall data collection and reporting. Students are also trained on rehydration techniques, including epicoelomic fuid administration. There are both lectures and hands on training followed by a written and hands on practical exam. Since the frst class in 2011, 114 students have completed the class and 68 currently are certi- fed to perform the health assessments.

The chytrid fungi (B. dendrobatidis, B. salamandrivorans) and viruses (Ranavirus sp) are responsible for mass mortalities in amphibians.1,2 Recently many feld and experimental studies in West Europe have shed light into the epidemiology and pathogenesis of these microorganisms. So far, similar studies and data are scarce3,4 or absent from East Europe and the Balkan Peninsula. Greece, in the southern tip of the Balkan Peninsula, offers a unique habitat for 23 amphibian species. Few of them (P.cretensis, P. ceringensis, L. helverseni) are endemic and their population is considered endangered or fragile.5 Our team has sampled more than 300 amphibians of different species and habitats, from mainland and insular Greece, in order to investigate the possible presence and distribution of these pathogens. From each individual, a skin, oral and cloacal swab was collected under standard methodology. Endemic and endangered animals received special attention in our study. During the feld sampling the team followed international biosecurity guidelines. All amphibians were returned unharmed to their original habitat. The samples were examined with conventional and real-time PCR, following standard methodology.6,7 So far we have traced B. dendrobatidis in 7% of the examined anurans (Bufotes viridis, Pelophylax ridibundus, P. epeiroticus, P. cretensis and Rana catesbeiana) from three different areas. No other pathogens were so far detected. The future of the project and the latest results will be presented and discussed. References 1.

Specifically, turtles and tortoises are generally perceived as providing no nest protection once the eggs are laid. Here, we describe observations of nest guarding by female gopher tortoises (Gopherus poly- phemus). Nest guarding among reptiles is considered uncom- mon (Reynolds et al. 2002).

Despite their family-wide homology of Z-specific gene content, previous cytogenetic studies revealed significant variability in the size, morphology, and heterochromatin distribution of their W chromosome. However, there is little evidence about the accumulation and distribution of repetitive content on lacertid chromosomes, especially on their W chromosome. In order to expand our knowledge of the evolution of sex chromosome repetitive content, we examined the topology of telomeric and microsatellite motifs that tend to often accumulate on the sex chromosomes of reptiles in the karyotypes of 15 species of lacertids by fluorescence in situ hybridization (FISH).

Genetic origins and population status of desert tortoises in Anza-Borrego Desert State Park, California: initial steps towards population monitoring. California Department of Parks and Recreation, Colorado Desert District, Borrego Springs, California. 89 pages. i FOREWORD The Desert tortoise (Gopherus sp.) was formally reported to science in 1861, and became the official California state reptile in 1972. Recent studies reveal three species, the Mojave desert tortoise (G. agassizii), Sonoran Desert tortoise (G. morafkai), and Sinaloan desert tortoise (G. evgoodei) (Murphy et al. 2011, Edwards et al. 2016; Figure 1). Range-wide declines in the Mojave desert tortoise population led California to prohibit the collection of this species in 1961. Despite this, it was emergency listed as federally endangered and state listed as threatened in 1989, and subsequently listed as federally threatened in 1990 (Federal Register 55, No 63, 50 CFR Part 17).

The modern European lizard fauna started to set up in the Miocene and a rich fossil record is known from Neogene and Quaternary sites. At least 12 lizard and worm lizard families are represented in the European fossil record of the last 23 Ma. The record comprises more than 3000 occurrences from more than 800 localities, mainly of Miocene and Pleistocene age. By the beginning of the Neogene, a marked faunistic change is detectable compared to the lizard fossil record of Palaeogene Europe. This change is reflected by other squamates as well and might be related to an environmental deterioration occurring roughly at the Oligocene/ Miocene boundary. Nevertheless, the diversity was still rather high in the Neogene and started to decrease with the onset of the Quaternary glacial cycles. This led to the current impoverished lizard fauna, with the southward range shrinking of the most thermophilic taxa (e.g., agamids, amphisbaenians) and the local disappearance of other groups (e.g., varanids). Our overview of the known fossil record of European Neogene and Quaternary lizards and worm lizards highlighted a substantial number of either unpublished or poorly known occurrences often referred to wastebasket taxa.

    Timon lepidus Region: 1 Taxonomic Authority: (Daudin, 1802) Synonyms: Common Names: Ocellated Lizard English Perleidechse German Lagarto Ocelado Spanish Sardao Portuguese Lezard ocelle French lucertola ocellata Italian Order: Sauria Family: Lacertidae Notes on taxonomy: This species was included in the genus Lacerta, but it is now placed in the genus Timon (Mayer and Bischoff 1996; Fu 1998, 2000; Harris et al. 1998; Harris and Carretero 2003), though Montori and Llorente (2005) retain it in Lacerta. It consists of a number of distinct genetic lineages of uncertain taxonomic status. Paulo (2001) suggested that the subspecies Timon l. nevadensis is a distinct species, but other lines of evidence are more indicative of subspecific status (Mateo et al, 1996; Mateo and López-Jurado 1994). General Information Biome Terrestrial Freshwater Marine Geographic Range of species: Habitat and Ecology Information: This species is widely found in Portugal and Spain; it is found as This species is found in open and dry areas of woodland, scrubland, isolated populations in southern, south-central and western France olive groves, vineyards, meadows, arable areas and sandy or rocky (north to Oleron Island), and in extreme northwestern Italy. It also sites. It is generally present in areas that have refuges such as bushes, occurs on some Atlantic islands along the Spanish and Portuguese stone walls, rabbit burrows and other holes. The females lay clutches of coasts. It is present on a few Mediterranean islands. It ranges from sea five to twenty two eggs. level up to 2,500m asl. The subspecies T.l. oteroi is endemic to Salvora Island in northwestern Spain.
