Isotoma arctica
Schött, H, 1893
Isotoma arctica is a of (Collembola) in the Isotomidae, first described by H. Schött in 1893. The species epithet 'arctica' indicates its association with Arctic regions. Springtails are small, wingless hexapods that play important roles in soil decomposition and nutrient cycling. As a member of the Isotoma, it likely exhibits the elongated body form typical of this group, though specific morphological details for this species require direct examination of or specialized literature.

Taxonomic Note
The GBIF match and Catalogue of Life both confirm Isotoma arctica Schött, 1893 as an accepted within the Isotomidae. The original description by Schött (1893) would require consultation for specific diagnostic characters. The Isotoma is diverse and species-level identification often requires examination of chaetotaxy, structure, and other microscopic features.
Arctic Collembola Ecology
Arctic springtails, including in Isotoma, are adapted to cold environments with short growing seasons. They typically inhabit the soil and litter layer, where they contribute to decomposition processes. Many Arctic Collembola exhibit cold strategies including freeze avoidance or freeze tolerance, though specific physiological data for I. arctica is not available in the provided sources.
