Genetic population structure of the grass snake ( Natrix natrix ) in human-altered landscapes in Switzerland
Six novel polymorphic microsatellite loci are presented for the grass snake (Natrix natrix), a species with declining populations in many regions. The number of alleles per locus ranged from two toExpand
Grass Snake Population Differentiation over Different Geographic Scales
The findings indicate regular gene flow between N. natrix subpopulations and show that this species also moves across intensively used terrestrial habitat, suggesting that conservation actions in landscapes altered by humans should focus on the maintenance of a habitat mosaic. Expand

05. Population dynamics of grass snakes ( Natrix natrix ) at a site restored for amphibian reintroduction
Monitoring of grass snakes on a site in eastern England restored for an amphibian reintroduction found that the snakes were temporarily resident within a patch of high quality habitat and moved through home ranges that included the study site, suggesting annual survival may be underestimated.

Gender Differences in Seasonal Movement of Dice Snakes in Histria, Southeastern Romania
An archaeological excavation site among ancient ruins in Histria, south-eastern Romania, that harbours several thousand dice snakes (Natrix tessellata ), is the focus of various ongoing studies. TheExpand
Habitat selection and range size of grass snakes Natrix natrix in an agricultural landscape in southern England
The range sizes and habitat preferences of nine adult European grass snakes (Natrix natrix) were determined from radio-tracking data obtained within a landscape of mixed deciduous woodland and pastoral fields in southern England, with a strong preference for habitat boundaries and interfaces and an avoidance of woodland and fields that were used for grazing.

Snakes and Monocultures: Habitat Selection and Movements of Female Grass Snakes (Natrix Natrix L.) in an Agricultural Landscape
The results clearly demonstrate that monocultures are a component of the habitat of female Grass Snakes during their summer activity period in the study area, however, the marked preference for edge habitats, and the response to particular microhabitat features, emphasizes the importance of a mosaic of habitats and structural heterogeneity of edge habitats for the conservation of this snake population.

Spatial Biology of Northern Watersnakes (Nerodia sipedon) Living along an Urban Stream
Abstract Fifty Nerodia sipedon living along two kilometers of an urban stream in northeastern Pennsylvania were radio-tracked over three activity seasons, yielding more than 2520 relocations. HalfExpand

Growth rates, maturation and sexual size dimorphism in a population of grass snakes, Natrix natrix, in southern Sweden
Females were found to grow faster, and to reach a larger size than males, and female fecundity was found to increase with size. Expand

Home Range, Movements, and Activity of the Eastern Worm Snake, Carphophis Amoenus Amoenus
Movements of 10 eastern worm snakes (Carphophis amoenus amoenus) were studied using radioisotope tagging and tracing techniques. The study was conducted at Robinson Forest, Breathitt County,Expand
Comparative Ecology of the Common Garter Snake (Thamnophis s. sirtalis), the Ribbon Snake (Thamnophis s. sauritus), and Butler's Garter Snake (Thamnophis butleri) in Mixed Populations
Relationships between soil types and small mammal distribution, the relationship of water proximity and salamander distribution, and the density and arrangement of leaves and twigs in relation to breeding warblers suggest that a species may select certain features of the environment which will give it the requirements to survive and reproduce.
