Summary
Abstract: Environmental physiology of three species of springtails (Hexapoda:
Collembola): (1) Isotoma klovstadi (Isotomidae), (2) Cryptopygus cisantarcticus
(Isotomidae) and (3) Friesia grisea (Neanuridae). We measured supercooling
points, diurnal shifts in supercooling points, cold tolerance, critical thermal
minima and maxima, tolerance to desiccation and haemolymph osmolality for all
three species, as well as total proteins, responses to and recovery from
desiccation, osmoregulatory ability, heat and cold shock responses and fine
scale spatial variation in physiology of Isotoma klovstadi.
