CCA ordination diagram of carabid communities and ecological variables (above axis I,II; below axis I,III). Only species with a weight range higher than 1% are represented. Species are named with the first three letters of their generic and the first three letters of their species names (e.g. ABA PAR: Abax parallelepipedus) and marked with stars. Ecological variables are represented by arrows. For species abbreviation see Table I. ALT: Altitude (m), TEMP: Temperature (◦ C), RAINFALL: rainfall (mm3) , FREEZEF: freeze free period (months), VEGP: vegetative period (months), HEIGHT: tree height (m), LEAFL: leaf litter layer cover (%), SHRUB: shrub cover (%), GRASS: grass cover (%), TREESPT: total number of tree species present.
