Temperature adaptations of Siberian Pterostichus species (Coleoptera: Carabidae)
Year: 2013
Type: article
Abstract: Thermopreferenda and supercooling points of the following Siberian species of Carabidae were examined: Pterostichus vermiculosus, P. montanus, P. brevicornis, P. kaninensis, P. dilutipes, P. subaeneus (= wagneri), P. ehnbergi, P. magus and P. drescheri.Thermopreferenda of the different species were invariable over their area of distribution and correlated with their distribution within natural zones and altitudinal bells. Species examined had no seasonal changes of thermopreferenda. Instar specific thermopreferenda were observed.The species examined demonstrated slight seasonal dynamics in supercooling points (SCP). All individual's were freeze intolerant. Age variations in SCPs were observed. Larvae demonstrated lower supercooling temperatures than adults, but there were no differences in SCPs between the sexes. The seasonal and age dynamics of the supercooling point temperature were similar for ail species of Pterostichus.
