Environmental variability is the main driver for the variation of biological characteristics (life-history traits) of species. Therefore, life-history traits are particularly suited to identify mechanistic linkages between environmental variability and species occurrence and can help in explaining ecological patterns. For ground beetles, few studies directly related species traits to environmen...
OVERVIEW There has been little research on the importance of Seasonally Frozen Ground (SFG), including permafrost, to many of the major processes in mountain environments. One reason has been the difficulty in measuring and estimating the areal extent of surface frost that occurs under seasonal snowpacks.
