Record #191590:

Coole Überlebenskünstler / Jürg Zettel.

Title: Coole Überlebenskünstler / Jürg Zettel.
Translated title: Cool survival artist.
Author(s): Zettel, Jürg.
Date: 2010.
Language: German.
In: Alpen : Zeitschrift des Schweizer Alpen-Clubs. (2010.), Vol. 1 (2010)
Abstract: Describes habitat, behaviour and life cycle of Isotoma saltans and other alpine glacier flea species (Onychiurus alborufescens, e.g.). Isotoma saltans (order Collembola) measures 1.5-2.5 mm and can jump several centimetres. Describes physiological adaptions, such as glycoproteins providing freezing resistance down to -20°C and special enzymes and cellular structures enabling movement at -15°C. Fleas inhabit small fissures in glacier surface, pools of meltwater, or shaded undersides of supraglacial rocks in summer (where eggs are typically found) and die rapidly above 12°C. Winter is spent at glacier/snow interface. Speculates that diet consisting of wind-blown organic matter (particularly conifer pollen) and algae may provide chemicals that inhibit freezing of gut contents.
