Appendix D. Details on the magnitude and pattern of midge infall around Lake Mývatn, Iceland 2008–2011.
Table D1. Sample size, mean, and standard error of total midge infall per cup (g dw/yr) as measured by lethal aerial traps along transects around Lake Mývatn, Iceland from May–August 2008–2011. Distance classes are approximate distances (meters) at which traps were set from the lake edge.
