Dispersal ecology and evolution provides a timely and wideranging overview of the fast expanding field of dispersal ecology, incorporating the very latest research. Seed attractiveness, measured as dispersal probability, was found to be related to broad interspecific differences in composition of elaiosome phytochemistry, to high concentrations of elaiosome fatty acids, and to larger diaspore width, length, mass, and elaiosome length.
