We studied the relationship between the geographic distribution of the Pallas’ spadefoot (Pelobates vespertinus) and the soil temperature regime at the eastern boundary of this species’ range (south-western West Siberia and northwest Kazakhstan). This species overwinters underground, burrowing down to 1.5 m or deeper and has poor frost tolerance – it is unable to withstand temperatures below 0 °C,

Different snake species may be active at various times of the day. In Europe, most snake species are predominantly diurnal, but about a third are partially or principally crepuscular and/or nocturnal. Here, we report the first instance of multiple in situ observations of the crepuscular and nocturnal activity of V. ammodytes in Bulgaria. Overall, usually as a result of general herpetological surveys

A hitherto unknown feeding mode among snakes is described for the colubrid snake Oligodon fasciolatus in Northeast Thailand. Three cases of O. fasciolatus using enlarged posterior maxillary teeth to cut open the abdomen of a live poisonous toad Duttaphrynus melanostictus and eat its organs are described. The snakes and toads fought vigorously, and the toads secreted toxic white liquid on the dorsum

The genus Microgecko Nikolskii, 1907 (Gekkonidae) currently includes eight species distributed from western Iran to north-western India and Pakistan. During field research in Iraq, we found a population of the genus near to the Darbandikhan Lake in the north-eastern part of the country. Because members of the genus are characterized by a higher level of morphological and genetic diversity, we investigated

Research on navigation in animals is hampered by conflicting results and failed replications. In order to assess the generality of previous results, male Bufo bufo were collected during their breeding migration and translocated to two testing sites, 2.4 and 2.9 km away, respectively, from their breeding pond in the north of Vienna (Austria). There each toad was tested twice for orientation responses

Clutch size and number of clutches per reproductive cycle are important life history traits that can be influenced by anatomical, physiological, evolutionary, and ecological factors. This report on the clutch size and number of clutches of an endemic Mexican whiptail lizard, Aspidoscelis costatus costatus (Cope, 1878), is based on a study of population at an unusually high elevation for a member of

In Chile, the presence of Mourning Gecko, Lepidodactylus lugubris Duméril & Bibron, 1836 has been recognized for Easter Island (Rapa Nui) from late 19th century. Here, we report the first observation of a juvenile specimen of L. lugubris in an urban zone of Santiago, Región Metropolitana, mainland Chile, representing the southernmost non-insular record in America for this invasive species. Moreover

Two previously known northernmost localities of Sharp-snouted rock lizard in Montenegro were the entrance of the Komarnica Canyon (Nevidio), and the middle part of the Tara River Canyon (village Tepca). It was presumed that Komarnica and Piva canyons were once corridors for the spreading of this species from the Eastern Adriatic sub-Mediterranean area to the Tara River Canyon in the north. However

Between December 2015 and December 2017 a total of 63 sea turtles were recorded as being stranded along the Algerian coast. The loggerhead sea turtle Caretta caretta was the most commonly stranded species (n = 44) (69.8%), followed by the leatherback Dermochelys coriacea (n = 18) (28.6%) and the green turtle Chelonia mydas (n = 1). There was a slight dominance of the adult size class for stranded loggerhead

Information on species richness and community structure is invaluable for guiding conservation and management of biodiversity, but is rarely available in the megadiverse biodiversity conservation hotspot of Philippines – particularly for amphibians and reptiles. This study provides the first report and characterisation of amphibians and reptile communities across primary habitat types of the Victoria-Anepahan

The phylogenetic relationships and possible origin of a putative non-native population of Podarcis muralis in Ukraine were assessed based on sequences of the mitochondrial gene cytochrome b. Phylogenetic analysis showed that the Ukrainian lizards belong to two distinct mitochondrial lineages (haplogroups), both occurring within the Central Balkan clade, which includes most of central and south-eastern

We analysed several morphological characters of 84 road-killed D. caspius individuals from different areas of southern Romania. Most presented asymmetries in the total number of temporal scales, the temporal row and the periocular and labial scales. Almost a quarter of snakes had scars, located especially on the head and tail; many individuals had multiple injuries. The lowest rate of individuals with

The southwestern part of the Balochistan Province is a faunal extension of the Iranian Plateau in Pakistan, harboring more than one-third of Pakistan’s known amphibian and reptile species. We carried out field visits in five districts of southwestern Balochistan during 2013–2017 to investigate the scale and hotspots of reptile poaching. We encountered 73 illegal collectors possessing 5,369 live reptiles

We report recent observations, two new locality records and an updated overview of the distribution of Dopasia buettikoferi (Lidth de Jeude, 1905) from Borneo, as well as photographic documentation of this species showing colouration and patterns in living individuals and the holotype. This note represents the first complete compilation of distributional knowledge of this rarely-encountered member

The poorly known semi-fossorial snake Blythia reticulata is a small, oviparous, worm-eating species found in northeastern India and neighboring countries. Here we report on multiple new distribution localities that extend the known geographic range of the species. In addition, we provide new information on the reproductive biology of the species based on egg-laying behavior data from a captive gravid

Information on demographic and life-history traits of endangered vertebrate species, such as sea turtles, is crucial for planning management and conservation actions. We applied skeletochronology of phalanges to estimate the age of loggerhead turtles, Caretta caretta, found dead stranded along the beaches of Campania (western Mediterranean) from 2013 to 2017. To obtain maturity data, we examined gonads

It is shown that the location data for the terra typica restricta of Testudo graeca and for the terra typica designata for Testudo graeca are based on an incorrectly assigned location. In fact, the original place corresponds to Santa Cruz, known today as Agadir (Morocco) and not the old Spanish fortress of Santa Cruz near Oran in Algeria. Accordingly, populations of Testudo graeca from the Agadir environment

This study presents the first molecular evidence of Macrovipera razii from central Zagros, more than 300 km north-west of its prior records in southern Iran. Molecular analyses based on mitochondrial cytochrome b sequences identified the individuals from central Zagros as a lineage of M. razii. Specimens from the new localities are separated by a genetic distance of 1.46% from the known populations

Acoustic species recognition in anurans depends on spectral and temporal characteristics of the advertisement call. The recognition space of a species is shaped by the likelihood of heterospecific acoustic interference. The dendrobatid frogs Allobates talamancae (Cope, 1875) and Silverstoneia flotator (Dunn, 1931) occur syntopically in south-west Costa Rica. A previous study showed that these two species
