In this study, our aim is to examine the correlates of ant species density in oak woodlands and grasslands in California and southern Oregon. At approximately 25 sites along a latitudinal gradient from southern California to southern Oregon, we will use standard sampling techniques to estimate species density. Specifically, at each site, we will place a grid of 25 pitfall traps with 5 m x 5 m spacing. Pitfall traps are plastic vials buried flush with the soil, partially filled with soapy water, and left out for 48 hours. At each site, we will also estimate the number of plant species within the grid and the canopy cover of the grid. For each site, we will compile climate data from local weather stations and use GPS units to determine a sites latitude, longitude, and elevation. All of these parameters will be entered into a multiple regression model to examine which combination of factors best predict ant species density. We hope to set up at least 2 sites within your reserve. We will use wire flags while at the site, but will remove them within about 48 hours.
