Figure 3. Earthworm cocoon (A), juvenile (B), and live adult (C) counts in soil within split bin mesocosms. Small points are counts per soil condition in each bin (n = 3), larger symbols represent averages, and whiskers represent standard deviation. The vertical lines on each plot indicate the average counts in the control bins. Point symbols and colors represent soil condition (filled gray = NS- = non-saline with baseline OM, filled black = S- = saline with baseline OM, open gray = NS+ = non-saline with elevated OM, and open black = S+ = saline with elevated OM). P-values on the right-hand side of the figure are for paired t-tests across treatments within bins and for t-tests between each treatment side and the control bins. P-values <0.05 are indicated in bold. Average counts and p-values are interpreted to rank earthworm occurrence across treatments.
