Abundance of predatory aquatic invertebrates among leaf pack treatments from first experimental run.

The a priori contrasts are the same as those reported in Table 3:(1) Local matching at within-species scale: leaf packs containing leaves from one local vs. non-locally growing red alder tree;(2) High vs. low diversity within species: leaf packs containing 12 leaves from 1 red alder tree vs. 2 leaves from each of 6 red alder trees;(3) High vs. low species diversity: leaf packs containing leaves from either multiple alder or multiple hemlock vs. mixtures of alder/ hemlock;(4) contrasting multiple alder vs. multiple hemlock mixed individual packs(5) contrasting hemlock/alder vs. alder/ vine maple/ bigleaf maple mixed species packs;(6) local matching at between species scale: leaf packs contain species that match vs. mismatch those growing in the adjacent riparian forest.Abundance of predatory aquatic invertebrates among leaf pack treatments from first experimental run.
