Table II
Nested subset-analysis of the pollination web calculated via NTC (Atmar and Patterson, 1995), BINMATNEST (Rodriguéz-Gironés and Santamaría, 2006) and NESTEDNESS (Ulrich, 2006a), T = temperature in degrees, Trandom = randomized mean temperature (1000 iterations), N = degree of nestedness, P = level of significance.
