Influence of substrate type and physico‐chemical conditions on macroinvertebrate faunas and biotic indices of some lowland Waikato, New Zealand, streams
TL;DR: In this article, the authors measured physico-chemical parameters and sampled macroinvertebrate faunas on inorganic substrates, wood, and macrophytes to investigate factors influencing invertebrate distribution and abundance in Waikato, New Zealand, lowland streams, and evaluated six biotic indices and a rapid bioassessment protocol for lowland stream environments.
Macroinvertebrate-wood associations during decay of plantation pine in New Zealand pumice-bed streams: stable habitat or trophic subsidy?
TL;DR: It is indicated that wood in pumice-bed streams enhances habitat for lotic invertebrates, and invertebrate community succession as wood passes through different stages of decay, and suggested that inputs of pine woody debris can provide a trophic subsidy to pum Icebed streams in production forest environments.
Diet of the crayfish Paranephrops zealandicus in bush and pasture streams : insights from stable isotopes and stomach analysis
TL;DR: Crayfish stomachs from streams in both native bush and exotic pasture settings were dominated by allochthonous material, and stable isotope analysis indicated a greater importance for invertebrate prey in terms of assimilation and incorporation into crayfish biomass.
Distribution of benthic invertebrates in acid, brown water streams in the South Island of New Zealand
TL;DR: Benthic assemblages were not associated strongly with measured physicochemical factors but streams in close proximity tended to have similar faunas, suggesting that the availability of suitable colonizers sets the limits to species richness and is important in determining the composition of benthicassemblages at a particular locality.
Composition and flight periodicity of adult caddisflies in New Zealand hill‐country catchments of contrasting land use
TL;DR: Flight periodicity may partly be a functional response to larval food availability, and several species of Trichoptera showed site specificity and most of these were found at the native forest site.
