摘要

The activity of soil microarthropods during winter were studied in alpine tundra and subalpine forest ecosystems in Colorado, USA. Microarthropods were collected in pitfall traps from soils beneath shallow and deep snowpack to assess the effect of soil surface temperature on activity in these respective ecosystems. Overall, microarthropod activity was positively correlated with soil surface temperature; pitfall collections with greater numbers of microarthropods were correlated with higher temperatures. However, this relationship was less evident in the alpine tundra than in the subalpine forest, suggesting that microarthropods were less sensitive to the range of temperatures observed here. Results indicate that microarthropods beneath snowpack inalpine tundra are as active as those observed in the subalpine forest, and that microarthropod activity in these ecosystems should be enhanced by increases in winter precipitation.
