Ecological distribution of small mammals in the De Long Mountains of northwestern Alaska
Douglass RJ. 1984. Ecological distribution of small mammals in the De Long Mountains of northwestern Alaska. Arctic. 37(2):148-154
(Adapted from author's abstract.) The ecological distribution of small mammals (<200g) was studied in the foothill tundra of the De Long Mountains. Three species of shrews and five species of microtine rodents were trapped on 15 live-trapping grids during 1978 and 1979. During late summer, up to six species of small mammals were captured per habitat type which ranged from wet meadow through mesic shrubland to dry ridges. Following snowmelt most habitats contained only a single species and some contained none. Only four habitat types were continuously occupied by small mammals during both summers. Species diversity was variable among habitats. Average population densities for the microtines were low and varied according to habitat type.
