Tolerance of high temperature and associated effects on reproduction in euedaphic Collembola.Studies show that tropical and mid-latitude terrestrial ectotherms are more vulnerable to global warming than species from high latitudes.  However, thermal tolerance studies from these regions still lack soil invertebrates.  In the present study, we investigated six euedaphic species of Collembola (of the genera Onychiurus and Protaphorura) sampled across latitudes ranging from 31° N to 64° N and determined their upper thermal limit (UTL) by static assays.
