Climatic niche data for presences and pseudo-absences of four desert plant species

Presence data for four plant species (Bromus rubens, Layia platyglossa, Phacelia tanacetifolia, and Salvia columbariae) scraped from the Global Biodiversity Information Facility for a section of Southern California along with matching climatic data from WorldClim. Pseudo absences were randomly selected within the same extent as the presence data (latitude: 35.28531- 36.56198; longitude: -120.2184- -116.7162) using the biomod2 package in R. WorldClim version 2.1 climate data was extracted at a resolution of 0.5 minutes (~1 km2) and pseudo absences were selected from the raster pixels not containing any presences. The number of pseudo absences selected was based on three times the number of presences for each species. All temperatures are in degrees Celsius. Data Headings: long = longitude lat = latitude ops_type = whether obersavation is a true presence or psuedo absence species = plant species presence = 1 for presence, 0 for absence bio1 = Mean annual temperature bio2 = Mean diurnal range (mean of max temp - min temp) bio3 = Isothermality (bio2/bio7) (* 100) bio4 = Temperature seasonality (standard deviation *100) bio5 = Max temperature of warmest month bio6 = Min temperature of coldest month bio7 = Temperature annual range (bio5-bio6) bio8 = Mean temperature of the wettest quarter bio9 = Mean temperature of driest quarter bio10 = Mean temperature of warmest quarter bio11 = Mean temperature of coldest quarter bio12 = Total (annual) precipitation bio13 = Precipitation of wettest month bio14 = Precipitation of driest month bio15 = Precipitation seasonality (coefficient of variation) bio16 = Precipitation of wettest quarter bio17 = Precipitation of driest quarter bio18 = Precipitation of warmest quarter bio19 = Precipitation of coldest quarter
