Description: Numbers of species on 42 British Isles, Area, Elevation, # of soil types, latitude, and distance from Britain. Authors fit: linear, log transformed, and "mixed" models (presumably adding small distance to Britain for the isle of Britain. Model 1: No variables transformed Model 2: All variables transformed Model 3: Only Area log transformed Model 4: Species and # soil types not transformed, all others log transformed Model 5: S not transformed, all IV's and their log transfromed Model 6: S and A log transformed, none of others transformed Model 7: All variables transformed except # soil types See second source for model with Britain removed Variables/Columns Island 1-20 Area 21-30 /* sq. km */ Elevation 32-38 /* max in meters */ Number of soil types 44-46 Latitude 50-54 /* Midpoint of Lat Range in Degrees North */ Distance from Britain 57-62 /* kilometers */ Number of species 65-70
