Table 1 Oribatid mite species found during this study, their mean body size and arboreal life style (0 = mainly ground living; 0.5 = both living at the ground [notably dead wood] and on bark/cryptogams; 0.75 = living in cryptogams or mainly arboreal; and 1 = arboreal) and the species’ mean abundances (per 60 cm branch) for each branch category (Y/O: young- vs old-crown branches; a/c: alone vs in contact with contrasting age class).

From: Large body size constrains dispersal assembly of communities even across short distances

  1. In bold: dominant species (representing together 74% of total oribatid abundance). Note that for the rarer species, zero abundance will reflect rarity rather than complete absence from the tree.
