Surface litter (a) litter decomposition (% of initial mass remaining); (b) litter N concentration; (c) litter N release (% of initial N remaining) and (d) termite activity (bags per plot, per harvest), for A. semialata and A. gayanus litter at the soil surface, in native and invaded plots. Open symbols represent A. semialata litter and solid symbols represent A. gayanus litter. Solid lines represent native plots, and broken lines represent invaded plots. Values are means ± SE (n = 5).
