Scolytinae/Platypodinae species species richness in 50 × 50 km grid cells across mainland USA with associated predictor variables

A list of georeferenced Scolytinae and Platypodinae occurrence records in the USA was extracted from the Bark and Ambrosia Beetles of the Americas Database. In addition to geographical coordinates, each record included species, status of nativeness (native or non-native in the USA), principal host type (either conifer or angiosperm), and feeding guild (true bark beetles, ambrosia beetles, and “other”. The geographic coordinates of all occurrence records of individual Scolytinae/Platypodinae species were used to calculate species richness in 50 × 50 km grid cells (in cases of multiple records of the same species inside one grid cell, only one record was considered). The final data thus consisted of 3,376 cells. The dataset also includes values of environmental and socio-economic predictor variables: (i) average annual mean temperature [°C]; (ii) annual precipitation total [mm]; (iii) human population density [no. inhabitants per cell]; (iv) average income per capita ; (v) total length of..., , # Scolytinae/Platypodinae species species richness in 50 × 50 km grid cells across mainland USA with associated predictor variables
