| Popis: | The author correlates the results of a twenty-one day pitfall trap program, where wolf spiders were trapped from the various habitats of the Moab area, Utah. Species partitioning land biotic associations are discussed for the six species found in the study area. A seemingly habitat restricted color variation of Pardosa sternalis (Thorell) is described. This report summarizes the results of a twenty-one day trapping program and correlates the biotic associations and relative abundance of ground dwelling wolf spiders of the desert floor. No prior studies have been reported on the spiders which live on the desert floor. Chew (1961) dealt solely with the spiders associated with the vegetation of the desert shrub community. The study area included the Arches National Monument near Moab, Utah, and the nearby Canyonlands National Park. The trapping period was from 15 June to 15 July, 1966. The Moab area, with elevation of 4,042 feet, is part of the Colorado plateau Province; it has an annual average temperature of 54.1 degrees Fahrenheit and an annual temperature range of -24 to 111 degrees Fahrenheit. The average annual precipitation is 9.52 inches, including an annual snowfall of 16.5 inches.' The region is subject to great fluctuation and extreme variation in both temperature and rainfall between the various seasons of the year. The summers are hot and dry with cool nights, while the winter is cold and windy. Most of the pre- cipitation falls as snow in January to May. June and July are the dry periods. HABITATS OF THE STUDY AREA. Six habitats are recognized in this portion of the Colorade Plateau Province: Rock Formations, Pinyon-Juniper Woodland, the Desert Shrub Community, the Washes, 1 "Climatic Summary of the United States" (U.S. Weather Bureau, section 21). |
