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:	Understanding animals' selection of microhabitats is important in both ecology and biodiversity conservation. However, there is no generally accepted methodology for the characterization of microhabitats, especially for vegetation structure. We studied microhabitat selection of three Vipera snakes by comparing grassland vegetation structure between viper occurrence points and random points in three grassland ecosystems: V. graeca in mountain meadows of Albania, V. renardi in loess steppes of Ukraine and V. ursinii in sand grasslands in Hungary. We quantified vegetation structure in an objective manner by automated processing of images taken of the vegetation against a vegetation profile board under standardized conditions. We developed an R script for automatic calculation of four vegetation structure variables derived from raster data obtained in the images: leaf area (LA), height of closed vegetation (HCV), maximum height of vegetation (MHV) and foliage height diversity (FHD). Generalized linear mixed models revealed that snake occurrence was positively related to HCV in V. graeca, to LA in V. renardi and to LA and MHV in V. ursinii, and negatively to HCV in V. ursinii. Our results demonstrate that vegetation structure variables derived from automated image processing significantly relate to viper microhabitat selection. Our method minimizes the risk of subjectivity in measuring vegetation structure, enables the aggregation of adjacent pixel data and is suitable for comparison of or extrapolation across different vegetation types or ecosystems.

Cím:	Hide or die when the winds bring wings: predator avoidance by activity shift in a mountain snake / Dávid Radovics, Márton Szabolcs, Szabolcs Lengyel, Edvárd Mizsei
Dátum:	2023

Megjegyzések:	Background - Understanding predator-prey relationships is fundamental in many areas of ecology and conservation. In reptiles, basking time often increases the risk of predation and one way to minimise this risk is to reduce activity time and to stay within a refuge. However, this implies costs of lost opportunities for foraging, reproduction, and thermoregulation. We aimed to determine the main potential and observed predators of Vipera graeca, to infer predation pressure by estimating the incidence and the body length and sex distribution of predation events based on body injuries, and to assess whether and how the activity of V. graeca individuals is modified by predation pressure. Results - We observed n = 12 raptor bird species foraging at the study sites, of which Circaetus gallicus, Falco tinnunculus and Corvus cornix were directly observed as predators of V. graeca. We found injuries and wounds on 12.5% of the studied individuals (n = 319). The occurrence of injuries was significantly positively influenced by the body length of vipers, and was more frequent on females than on males, while the interaction of length and sex showed a significant negative effect. The temporal overlap between predator and viper activity was much greater for the vipers' potential activity than their realised activity. Vipers showed a temporal shift in their bimodal daily activity pattern as they were active earlier in the morning and later in the afternoon than could be expected based on the thermal conditions.Conclusion - The time spent being active on the surface has costs to snakes: predation-related injuries increased in frequency with length, were more frequent in females than in males and occurred in shorter length for males than for females. Our results suggest that vipers do not fully exploit the thermally optimal time window available to them, likely because they shift their activity to periods with fewer avian predators.
