However, it is known that some species enter a reproductive diapause when reared at constant temperature in the laboratory (e. g., the collembolan Hypogastrura tullbergi), and that this diapause can only be terminated by exposure to cold.
Population dynamics of two collembolan species in an Arctic tundra.
For example, one species of collembolan, Folsomia regularis, may constitute 60% of the total collembolan density in the polar desert .
The collembolan Vertagopus brevicaudus a "steppe" species; bbizonal steppe and tundra species; cthis group characterizes the southern tundra subzone; dthis group is relatively small, but is valuable in subdividing the tundra zone into subzones.
For example, one species of collembolan, Folsomia regularis, may constitute 60% of the total collembolan density in polar deserts.
Other noteworthy fauna include cave-dwelling species such as a collembolan Tricanthella frigida, an endemic found in Gavarnie cirque at 2,500 m, and coleopteran Tipnus unicolor and Speonomus bolivari.
