Arthropods play an important role in providing ecosystem services and are integral to terrestrial food webs. Given their importance, recent evidence suggesting widespread declines in arthropod populations has received considerable attention from scientists, politicians, and the public. While pollinator declines have been documented in North America, most evidence of declines has come from international studies. We are examining long-term changes in arthropod populations in Illinois using a 21-year data set of standardized sweep net samples taken in > 500 randomly selected forest, grassland, and wetland sites. In addition to temporal trends, we are investigating the importance of weather variables, landscape context, and plant-community composition for influencing arthropod populations.
