AbstractOur objectives are to examine the influence of the difference in stress tolerance among species on patterns of nestedness and to test whether a set of several small ponds supports more species than a few large ponds of equal area. Although fish species assemblages for each group of all fish, tolerant and intolerant species were significantly nested, intolerant species showed stronger nested tendency than tolerant species, suggesting that the tolerance of species can influence the patterns of nestedness. These results suggest that the tolerance of species can influence the patterns of nestedness. As for the comparison of cumulative species richness in small ponds and large ponds, although small ponds supported more species for tolerant species, there was little difference for intolerant species.
