Abstract
ABSTRACT The geographic distribution of species of Glyptasida Casey, 1912 ranges from along the western edge of the Great Plains from southern Canada to northern Jalisco, Mexico and west into Utah. Species and habitat associations of these beetles are here analyzed using a powerful geospatial dataset created by layering four habitat attributes (land cover, elevation, precipitation, and temperature) with locality data from museum specimens. Individuals of Glyptasida are associated with shrubland and grassland of temperate and tropical biomes. Species are found between 380 and 3,035 m elevation, in areas receiving 15–92 cm of precipitation and experiencing temperatures between -7° and 30°C annually. The distribution of Glyptasida conforms to the elevation and precipitation patterns in shrubland and grassland areas. Distribution cuts across temperature patterns, and therefore temperature does not appear to restrict the distributions of Glyptasida species. Geospatial considerations indicate favorable conditio...
