env_layers.zip this file contains the environmental data used in species distribution modeling in "STRONG PREMATING REPRODUCTIVE ISOLATION DRIVES INCIPIENT SPECIATION IN MIMULUS AURANTIACUS" Sobel and Streisfeld, Evolution Within the folder, there are 10 .asc files that contain the gridded environmental data specific to San Diego County, CA, USA. Files come from the following sources: 1) bias.asc: a bias layer incorporated into distribution modeling to account for variation in grid size of Worldclim layers across relatively large spans of latitude. 2) bio1.asc: Annual Mean Temperature 3) bio4.asc: Temperature Seasonality 4) bio5.asc: Max Temperature of Warmest Month 5) bio6.asc: Min Temperature of Coldest Month 6) bio12.asc: Annual Precipitation 7) bio15.asc: Precipitation Seasonality 8) bio16.asc: Precipitation of Wettest Quarter 9) bio17.asc: Precipitation of Driest Quarter 10) geology.asc: basic geologic bedrock material climate data are from: 8 Bioclim layers from the publicly available Worldclim current conditions (~1950-2000) 30 arc-second resolution Global Climate Data database address: http://www.worldclim.org/bioclim accessed: February 1, 2012 Geology data were from: US Geologic Survey address: www.usgs.gov accessed: February 1, 2012 Geology data are coded as numerical categories, with the following key: VALUE ROCKTYPE 0 andesite 1 argillite 2 greenschist 3 sandstone 4 diorite 5 peridotite 6 intermediate volcanic rock 7 gabbro 8 alluvium 9 water 10 slate 11 schist 12 mafic volcanic rock 13 serpentinite 14 landslide 15 dune sand 16 blueschist 17 glacial drift 18 conglomerate 19 phyllite 20 limestone 21 mudstone 22 shale 23 dacite 24 granodiorite 25 gneiss 26 sand 27 greenstone 28 plutonic rock 29 metasedimentary rock 30 chert 31 melange 32 quartzite 33 basalt 34 rhyolite 35 siltstone 36 hornfels 37 metavolcanic rock 38 felsic volcanic rock 39 tephrite (basanite) 40 dolostone 41 trachybasalt 42 peraluminous granite 43 mica schist 44 quartz monzonite 45 orthoquartzite 46 granite 47 marble 48 anorthosite 49 tonalite 50 quartz diorite 51 pelitic schist
