Item Open Access Arthropod diversity and abundance on a suburban remnant of the Shortgrass Steppe(Colorado State University. Libraries, 2005) Hartley, Laurel, author; SGS-LTER, Colorado State University, publisherArthropod censuses are recorded on the Shortgrass Steppe Long Term Ecological Research site and Pawnee National Grasslands as a part of long term ecological monitoring. As the front range becomes developed, remnants of the shortgrass steppe become surrounded by human habitation. Subsequently there are increased efforts to control "pest" insect species, an increase in water availability, changes in insect food sources, and changes in predator species. These environmental changes are likely to affect arthropod communities. Long term monitoring of arthropod communities on a remnant shortgrass steppe enclosed by development may provide baseline data useful for local agencies creating management plans for natural areas along the front range.Item Open Access Arthropod studies on the Shortgrass Steppe LTER: past, present and future(Colorado State University. Libraries, 2000) Hartley, Laurel M., author; Kaplan, Nicole E., author; Lindquist, Mark D., author; Stapp, Paul, author; SGS-LTER, Colorado State University, publisherArthropods play important roles in the ecology of shortgrass steppe as consumers, prey and detritivores. Here we describe past, ongoing, and future studies of arthropods conducted as part of the Shortgrass Steppe (SGS) LTER project in north-central Colorado. Our goals are to increase awareness of our arthropod research and existing datasets, and to identify opportunities for collaboration and cross-site comparisons with LTER researchers. Arthropods have been the focus of much short-term comparative and experimental research on the site, but we know of only two long-term studies. Since 1995, insects and spiders have been sampled monthly during summer (May- September) in live pitfall traps along a 1-km transect spanning a representative topographical gradient (catena). This project continues research conducted by other SGS-LTER scientists from 1990-1994 to investigate spatial dynamics of darkling beetle (Tenebrionidae) populations. A second project initiated in 1998 involves monthly summer sampling of macroarthropods in small pitfall grids in grassland and saltbush vegetation. This study was implemented to track changes in relative abundance of arthropod prey, and grids are located on trapping webs used for rodent population studies. In addition, we maintain on-site a small but growing reference collection of representative arthropods, which is mostly used to train field assistants and support other research projects.
