APPENDIX 1. Fruit characteristics and distribution at sites of plant species. Species names follow Beadle, Evans and Carolin (1984). List is alphabetical by genus but not otherwise sorted. 'Disp. type' means dispersal morphology (see text): 1 = no special morphology, 2 = air-resistance, 3 = vertebrate-adapted fleshy fruit, 4 = ant-adapted food body, 5 = both ballistic and ant-adapted, 6 = ballistic, 7 = uncertain, 8 = exozoochore, 9 = both vertebrate and ant-adapted. Growth forms: 1 = herbs and shrubs usually less than 50 cm tall; 2 = shrubs 50-200 cm tall; 3 = shrubs growing to more than 2 m tall, and trees; 4 = climbers, twiners and vines. Weights+s.d. of whole diaspores are based on minimum of 5 mature fruits unless otherwise noted. Weights were measured to three significant figures and are given in mg. The components are 'disp struc' -- structures clearly functioning to procure dispersal; embryo and endosperm - - tissues providing metabolic reserve for the developing seedling; and 'other struc' -- any tissues not in either of the other categories, for example the testa which could not be clearly attributed either to a dispersal adaptation or to an establishment adaptation. Oven-dry weight is given as a percentage of fresh weight for each of these components. Cases when there were multiple embryos within a diaspore, and other complications, are dealt with in the footnotes. When fresh weights of the three components add to less than fresh weight of whole diaspores, three reasons can account for this: there are several seeds per diaspore and component weights are given on a per-seed basis (this is footnoted when it occurs); or the seed(s) dissected were smaller than average; or seed components, usually fleshy parts, lost water during dissection before they could be weighed. Presence at the eight sites (1-4 relatively fertile soil, 5-8 infertile soil) is given to the nearest percentage cover, or '+' indicates less than 0.5% cover.
