Megjegyzések:	Understanding the factors that determine the abundance of populations is of key importance in conservation biology, ecology, and biogeography. For grassland-associated species, such as the Hungarian meadow viper (Vipera ursinii rakosiensis), habitat management is particularly important. We aimed to study the effects of the three most common types of grassland management (grazing, mowing, and mowing + grazing) on the abundance of reptile species in meadow viper habitats in Kiskunság National Park, in Hungary. We surveyed grasslands repeatedly (n = 15 occasions) for reptiles in one autumn and one spring season in three 1-ha quadrates per grassland management type. We recorded all reptiles and their activity related to operative temperatures and analyzed data by n-mixture models. All reptile species known to occur in the habitats were observed during the surveys, but only the green lizard, sand lizard, and Hungarian meadow viper reached the minimum number of observations required for detailed analyses. Grazing had a strong positive effect on the abundance of Hungarian meadow vipers and sand lizards, while both mowing and mowing + grazing rotation had a negative effect. None of the grassland management types affected green lizard abundance. Our results suggest that grazing is the ideal type of grassland management for the endangered Hungarian meadow viper and the sand lizard. Mowing and mowing + grazing should be replaced by grazing to ensure the effectiveness of habitat management for conservation and to maintain healthy populations of grassland-associated reptile species.

Megjegyzések:	The Hungarian meadow viper (Vipera ursinii rakosiensis) is an endangered subspecies of Vipera ursinii, which faces high predation pressure, partially due to avian species. To create a systematic method for estimating the measure of predation pressure, we developed a geometric morphometric approach to identify both undamaged and damaged vertebrae of snake species found in Hungarian meadow viper habitats from raptor feeding remains. We used linear discriminant analysis with a reference material of vertebrae from identified snake species as training data. We also tested its efficiency by predicting the identification results of different simulation levels based on vertebra completeness. We practiced this method on vertebrae of unknown species of snakes obtained from nests and pellets of short-toed snake eagles (Circaetus gallicus, n = 9), common buzzards (Buteo buteo, n = 14) and Montagu's harriers (Circus pygargus, n = 3). The identification approach showed high accuracy, even in the case of missing landmarks to some extent. We identified vertebrae remnants of Natrix natrix (n = 172, 83.9%), Coronella austriaca (n = 10, 4.9%) and V. u. rakosiensis (n = 23, 11.2%). Both, the reptile specialist C. gallicus and the generalist B. buteo proved to be preying on V. u. rakosiensis, while samples of C. pygargus did not contain any snake remains despite of previous observations of V. ursinii predations. Our approach is applicable for other studies and taxa as well, therefore can be a practical tool for classification of incomplete vertebrae, which is otherwise hardly identifiable. Furthermore, it could be applied to help estimate predation pressure on endangered snake species.
