Littoral macroinvertebrate communities of dune lakes in the far north of New Zealand

摘要: The littoral macroinvertebrate faunas of 17 dune lakes on the Aupouri Peninsula in northern New Zealand were examined. Land cover individual catchments was principally sand dunes and scrub, plantation forest, pasture, or a mixture forest pasture. Sampling concentrated sedge beds, submerged macrophytes surface sediment layers zone. Sixty-eight invertebrate taxa recorded, 11–30 per lake. Relative abundance major faunal groups differed considerably among but core group common species found three quarters them. Neither community composition, nor various measures richness related significantly to catchment land classes. A feature lake fauna occurrence introduced Gastropoda eight self-introduced insect species, including five dragonflies. One latter, Hemicordulia australiae, all made up 3% invertebrates collected.
