Electronic supplement 1Species of benthic invertebrates collected at the 17 study sites within OtagoHarbour, South Island, New Zealand. * Denotes 49 common species whose mean abundance was entered as dependent variable in separate multiple regression analyses (see Fig. 2). Information on main feeding type (predator, deposit-feeder, filter-feeder and grazer) and general mode of life (in- or epifaunal) was extracted from a range of local handbooks and electronic library databases or based on personal observation
