Anoxia tolerance in high Arctic terrestrial microarthropods
Abstract. 1. Ten Arctic species of Collembola and two species of cryptostigmatic mites survived anoxia at 5 °C over periods ranging from 1 to 36 days. 2. Highly active, surface‐dwelling collembolans such as Isotoma anglicana , Isotoma tschernovi , and Sminthurides malmgreni were the most susceptible...

| Summary: | Abstract. 1. Ten Arctic species of Collembola and two species of cryptostigmatic mites survived anoxia at 5 °C over periods ranging from 1 to 36 days. 2. Highly active, surface‐dwelling collembolans such as Isotoma anglicana , Isotoma tschernovi , and Sminthurides malmgreni were the most susceptible to anoxia. Mites and Collembola living deeper in the soil or in wet habitats, such as Camisia anomia and Hypogastrura viatica , were most tolerant. Tolerance, however, appears more closely linked to taxonomic relatedness than to ecological groupings per se , although the two may coincide. 3. Implications for life‐history strategies, including metabolic cold adaptation in its broadest sense, are discussed. |
