Population dynamics of two collembolan species in an Arctic tundra.    From Wordnik.com.  [General characteristics of arctic species and their adaptations in the context of changes in climate and ultraviolet-B radiation levels] Reference

For example, one species of collembolan, Folsomia regularis, may constitute 60% of the total collembolan density in polar deserts.    From Wordnik.com.  [Arctic environments north of the treeline] Reference

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.    From Wordnik.com.  [Pyrenees-Mont Perdu, France and Spain] Reference

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.    From Wordnik.com.  [Conservation of arctic species] Reference

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.    From Wordnik.com.  [Implications of current species distributions for future biotic change in the Arctic] Reference
