Dinarolacerta mosorensis and D. montenegrina are allopatric and closely related rock lizards endemic to the Dinaric Mountains of the Balkan Peninsula. We analysed their habitat characteristics and relative abundances in the mountains of Montenegro. We found significant differences in structural features of the microhabitat used both between populations of D. mosorensis and the two species. Dinarolacerta mosorensis was associated with relatively more shaded and damper spots on rocks closer to vegetation and leaf litter, while D. montenegrina was found in more open, rocky situations. There were significant differences in relative abundance between the sampling sites. Generally, the studied lizards were more abundant at sites with greater percentage of leaf litter and lower percentages of bare ground and small rocks, despite the lower frequency of available refuges in these places. Our results provide basic information that could assist in the adoption of adequate management practices for protection or restoration of habitat attributes relevant to these vulnerable (D. mosorensis) and endemic species. © 2017 Deutsche Gesellschaft für Herpetologie und Terrarienkunde e.V.

The Mosor rock lizard (Dinarolacerta mosorensis) is a distinctly flattened endemic species that occupies discontinuously distributed rocky areas at high elevations in the Dinaric Mountains of the Balkans. The body size, age structure, longevity, survival rates and growth patterns of this species were studied using skeletochronology and back-calculation methods. The modal age was found to be 5 years for males and 6 years for females, while the maximal longevity was found to be 9 years in both sexes. The age and body length were positively correlated in both sexes. Both sexes reached maturity at 3 years, with a snout-vent length of 53.3 and 56.5 mm for males and females, respectively. The growth coefficient had significantly higher values in females (0.54) than in males (0.40). The asymptotic size of females was lower (66.01 mm) than that of males (70.82 mm). The growth rate of females decreased soon after maturation whereas males continued to grow for a longer time. Juveniles had lower survival rates than adults (0.5 vs 0.7). The effective age at maturity (13.5 months) was significantly greater than that for the small lacertid lizards living at the low altitudes of a Mediterranean climate, greater than but within the range of values predicted for those living at low altitudes of a temperate climate, and lower than but within the range of values predicted for montane small lacertids.

This study analyzes the degree of morphological differentiation among populations of the common toad Bufo bufo in the central part of the Balkan Peninsula. Variations in a number of morphometric and qualitative characters in 14 population samples were analyzed using univariate and multivariate statistics. We found a high degree of female-biased sexual size dimorphism. Morphological variation among the samples was more expressed in morphometric than in qualitative characters. The significant size differences that exist between northern and southern population groups could be the result of phenotypic plasticity. Our results do not support a clear split between northern and southern populations, contrary to the current taxonomic treatment of these groups as B. b. bufo and B. b. spinosus, respectively.

We present basic data on the female reproductive traits and diet of the lacertid lizard Algyroides nigropunctatus from Bisage island in Lake Skadar (Montenegro) in late spring. Individual females commonly laid clutches of three (range 2 - 5) eggs with an average mass of 0.40 g. At least two clutches were produced in a breeding season. The female body size had no effect on clutch and egg size. There was no evidence of the predicted trade-off between egg size and clutch size. The diet was composed of various types of invertebrates, basically small arthropods, and also small amounts of plant material. Araneae and Coleoptera were the most common and the most important food items. © NwjZ, Oradea, Romania, 2013.

We applied a geometric morphometrics approach to examine sexual size and shape dimorphisms (SSD and SShD) in dorsal and ventral skull portions and cephalic scales (pileus) in the lacertid lizard Algyroides nigropunctatus. We found significant sexual dimorphism in all three structures that are mostly attributable to allometry. Males and females share allometric trajectories for the pileus and dorsal portion of the skull, i.e. the significant differences in shape between sexes are due to differences in size. Regardless of sex, allometric shape differences between small and large individuals show negative allometry in the anterior parts and more pronounced positive allometry of the parietal region in the dorsal skull and pileus. We observed a marginally significant divergence in sex-specific allometric trajectories of the ventral skull. The similar patterns of covariation between the ventral skull and the dorsal skull portion and pileus indicate close relationships between the skull bones and cephalic scales. The stronger covariation between the ventral and dorsal skull portion in males compared to females raises the question whether sexual dimorphism in the structure of morphological variation of the lizard skull exists.

In this paper, we present the results of a study conducted in the Great Ulcinj Beach area, including its hinterland and Ada Island. In the study area, we recorded 10 species of amphibians (Lissotriton vulgaris, Bombina variegata, Bufo bufo, Pseudepidalea viridis, Hyla arborea, Pelophylax ridibundus, Pelophylax lessonae, Pelophylax shqipericus, Rana dalmatina, and Rana temporaria) and 20 species of reptiles (Testudo hermanni, Emys orbicularis, Mauremys rivulata, Caretta caretta, Hemidactylus turcicus, Lacerta viridis, Lacerta trilineata, Podarcis muralis, Podarcis melisellensis, Anguis fragilis, Pseudopus apodus, Natrix natrix, Natrix tessellata, Hierophis gemonensis, Dolichophis caspius, Zamenis longissimus, Elaphe quatuorlineata, Malpolon insignitus, Telescopus fallax, and Vipera ammodytes). Mauremys rivulata and Telescopus fallax were recorded for the first time in this area. © TÜBİTAK.
