The brain is among the most energetically costly organs in the vertebrate body. The expensive-tissue hypothesis (ETH) predicts that increasing the size of another costly organ, such as the gut, should compensate for the cost of a small brain. To date, this hypothesis has mainly been tested in homoeothermic animals and in some ectothermic animals (e.g., fishes and anurans). Here, we undertake a test of the ETH by analyzing the relationship between brain size variation and length of the digestive tract in Hylarana guentheri . After controlling for geographical situation and body size, we did not find a correlation between brain mass and the length of the digestive tract in H. guentheri . Our findings suggest that the variation of brain size did not follow general patterns in this species and that the effect of diet quality cannot play a role in the variation of brain.

We analysed variation of dorsal yellow patterns in 2077 individuals that represented 23 populations from the northern parts of the Sudetes and the Carpathian Mountains. We distinguished four types of yellow patterns: spotted (50.1%), spotted-and-striped (42.8%), zig-zag (5.8%), and striped (1.3%). Spotted form dominated in the east (69.2%, the Carpathians) and its frequency decreased to the west (46.4%, the Sudetes), where spotted-and-striped forms became more common. The rarest in both mountain ranges (0.9% in the Carpathians, 1.3% in the Sudetes) was striped type. The exception was the westernmost population represented by 15.8% of the striped individuals. We did not find evidence of differences between yellow colouration variants and genotypes of 557 individuals defined by 10 microsatellite loci. No differences were found between females and males. We concluded that patterning does not constitute a unique feature at population and mountain ranges levels.

Salamandra atra atra is the most widespread subspecies of the Alpine Salamander, both in Italy and in the other parts of the species distribution range. However, in particular for Italian populations, its ecology and demographic parameters are poorly known. We studied biometry (length, mass, body condition index) and demography (population density, sex ratio, proportion of gravid females) of this fully terrestrial salamander in the “Paneveggio-Pale di San Martino” Natural Park in the Dolomites. We used removal methods to estimate abundance on a surface of about 1000 m 2 . Density estimate of adults was 472 salamanders/ha, which falls within the density estimates that are available for this taxon . Sexes did not differ significantly in size and body mass. Body sizes of adults included the maximum sized salamander recorded in Italy. There was a high rate of gravid females (50%), which were comparable in size with non-gravid females. Males and non-gravid females did not show significant differences in their body condition index.
苏门答腊蝾螈是阿尔卑斯蝾螈中分布最广的亚种，分布在意大利和物种分布范围的其他地区。然而，特别是对于意大利人口来说，其生态和人口参数鲜为人知。我们在多洛米蒂的“Paneveggio Pale di San Martino”自然公园研究了这种完全陆地蝾螈的生物计量学（长度、质量、身体状况指数）和人口学（种群密度、性别比、怀孕雌性的比例）。我们使用去除方法来估计约1000m2表面上的丰度。成年蝾螈的密度估计为472只/公顷，属于该分类单元的密度估计范围。性别在体型和体重上没有显著差异。成年蝾螈的体型包括意大利记录的最大体型蝾螈。怀孕的女性比例很高（50%），其体型与未怀孕的女性相当。雄性和未怀孕的雌性在身体状况指数上没有表现出显著差异。

Chicken turtles ( Deirochelys reticularia ) are generally characterized as having atypical reproductive characteristics relative to other sympatric emydids. However, the comparatively understudied western chicken turtle ( D. r. miaria ) has been shown to exhibit some reproductive characteristics that differ from the other subspecies. Therefore, we examined clutch and egg sizes from six D. r. miaria (13 clutches) in Oklahoma and compared the results to values that have been reported for the other two subspecies. Females nested up to three times per year, with clutches ranging from 8-13 eggs per clutch (mean = 10.9). The eggs were 19.4-25.3 mm wide (mean = 22.2 mm). These values are greater than the means reported for the other subspecies, but the differences were not statistically significant.

Facultative paedomorphosis occurs rarely in the genus Triturus compared to other European newts such as Ichthyosaura alpestris and Lissotriton spp., with most of observation related to single or few individuals per site. In this paper we report about body size, age and population size of two populations of Triturus carnifex with paedomorphs. Since one of the populations consisted of approximately 25% of paedomorphs, this is the first study about a population of large-bodied newts with a conspicuous number of paedomorphic individuals. We found evidences for an ecological causation of paedomorphosis, as well as further support for two recent findings about paedomorphosis: the reduction of sexual size dimorphism and the female-biased sex-ratio within paedomorphs.

The genus Anguis is known to be mainly continental in the Mediterranean area, and accordingly it has never been recorded in Western Mediterranean islands. Here we report for the first time the presence of the slow worm in a Western Mediterranean island, the Ile Sainte-Marguerite from Lerins archipelago (southeastern France). The molecular analysis of ND2 and PRLR genes assigned the specimens to A. veronensis Pollini, 1818 and showed that they are genetically related to the mainland population from Les Mayons, in mainland France.

Skeletochronology is a reliable tool for assessing several parameters in amphibian populations. We used skeletochronology to determine the age structure, growth rate, age at first reproduction, and longevity of Levantine frog Pelophylax bedriagae populations from different localities in Denizli, Turkey. All examined individuals (N = 161) exhibited Lines of Arrested Growth in the bone cross-sections. Age structure and age at first reproduction were similar among localities and sexes, while longevity and growth rates showed significant variation among localities. Obtained results were compared with literature data on age-related and grow parameters in Pelophylax bedriagae and cognate species.

Fungal infections are causing widespread population declines and extinctions in all vertebrate classes. Among them, an important fungal disease chytridiomycosis, caused by the pathogenic chytrid Batrachochytrium dendrobatidis ( Bd ). With an aquatic infectious phase, Bd does not survive desiccation for long, but may be transported by non-amphibian carriers. Such mechanism is key to understand amphibian-chytrid dynamics and may contribute to local amphibian conservation action plans. Therefore, we surveyed Bd in reptiles from two different Brazilian rainforests, looking for possible Bd carriers. We sampled 35 individuals belonging to 11 squamate families, five from the Atlantic Forest and 30 from the Amazon. We detected Bd in one adult lizard, Placosoma glabellum . This lizard feeds, shelters, and breeds in the leaf-litter, and moves between Atlantic Forest streams. Hence, it may be carrying Bd from stream to stream, and also spreading the pathogen to direct-developing amphibians, which have no contact with water bodies and are more susceptible to chytridiomycosis than aquatic species. This is the first record of a non-amphibian chytrid carrier in South America. We suggest that additional field and museum samplings will contribute to understand whether Bd can actually infect reptiles, and how reptile carriers can affect chytrid dynamics in the wild.

Knowledge about endoparasites of snakes is essential to understand the ecology of both parasites and hosts. Herein, we present information on helminths parasitizing the black false boa Pseudoboa nigra in northeastern Brazil. We examined 32 specimens from five Brazilian states (Ceara, Piaui, Pernambuco, Maranhao and Rio Grande do Norte). We found six helminths taxa: two acanthocephalans ( Acanthocephalus sp. and Oligacanthorhychus sp.), three nematodes ( Hexametra boddaertii, Physaloptera sp. and Physalopteroides venancioi ), and one cestode ( Ophiotaenia sp . ). All parasites are reported for the first time infecting P. nigra , providing relevant information on infection patterns in this snake.

Batrachochytrium dendrobatidis ( Bd ) is a fungal pathogen which causes the emerging infectious disease chytridiomycosis. Bd presents low host specificity and threatens amphibians worldwide, thus systematic inventory is the key in order to detect and mitigate the effects of the disease. Extensive data collection was conducted in Hungary in 2009-2015 from fourteen different areas. Combined data – recent field sampling on sixteen taxa and the examination of archived Bombina spp. specimens – from 1360 individuals were analysed with qPCR. Two sentinel taxa, Bombina variegata and the members of the Pelophylax esculentus complex were marked to monitor the occurrence of Bd in two core areas (Bakony Mts and Hortobagy National Park, respectively) of sampling. Climatic variables were also examined in core areas to test their effect on prevalence and infection intensity. Among the sixteen sampled amphibian taxa seven tested positive for Bd and the overall prevalence in Hungary was 7.46%. Among the ethanol-fixed Bombina spp. individuals Bd was not detected. In the first core area (Bakony Mts) the overall prevalence in B. variegata was 10.32% and juvenile individuals showed significantly higher prevalence than adults. On the other hand there was a significant negative relationship between infection prevalence and monthly mean air temperature. Finally, in the other core area (Hortobagy National Park) the overall prevalence in P. esculentus complex was 13.00%, and no differences were found in prevalence or infection intensity between sexes, sampling years or age classes.
