Amphibian whole life cycle predictors - 10m resolution

Amphibian whole life cycle predictors include 6 variable types: (1) Topographic – slope °: derived from the Swiss Topographical Landscape model (swissTLM 3D 2015) at 2 m resolution (elevation uncertainty ± 0.5m) and, subsequently, aggregated to a median value; (2) Hydrologic: two predictors including nearest distance to water m (all water-related objects and rasterized lotic, lentic and reedbeds from the regional cadastral maps – AV: Daten der Amtliche Vermessung) and runoff coefficient C (between 0 and 1 relating amount of runoff to amount of precipitation, mapped AV: Daten der Amtliche Vermessung data against literature values for different land covers); (3) Edaphic – soil moisture variability (not available): can gathered from the spatial modelling of Ecological Indicator Values in Switzerland (Descombes et al., 2020) and resampled from 100m to 10m; (4) Vegetation: we calculated the median and standard deviation of the Normalized Difference Vegetation Index (NDVI) from all available cloud free Sentinel-2 pixels available between April and October for the years 2016 to 2019 (Drusch et al., 2012) and the median vegetation height m (not available) can gathered from Ginzler and Hobi (2015); (5) Land-use derived: includes three predictors, grassland density grassland/cell (not available) - can be gathered from Pazur et al. (2021), total grasslands area evaluated using a spatial weight matrix and a 250m neighborhood radius around each cell; urbanization buildings/cell – average building density for a 250m neighborhood around each cell based on the AV: Daten der Amtliche Vermessung ; and traffic intensity vehicles/day – average daily vehicle count (Nationales Personenverkehrsmodells); (6) Movement-ecology related: includes three predictors of proximity – nearest forest distance m; nearest rock-gravel and sandy area (RGS) distance m and nearest road distance m (considering any road type) – all calculated based on the AV: Daten der Amtliche Vermessung maps.
