“…Siltation of stone surfaces adversely affects algal grazers (e.g., see Rabeni & Minshall 1977; and this along with a paucity of suitable substrata (i.e., cobbles), may account for the low densities of Aphwphila neozelandica, Leptophlebiidae, Pycnocentrodes spp., Pycnocentria evecta, and Potamopyrgus antipodarum found in runs of the Kiripaka. The high densities of Paracalliope fluviatilis and Megaleptoperla diminuta in runs are consistent with reports of their presence in streams with a shallow gradient and moderate to slow flow (e.g., see McLellan 1977;Winterbourn & Stark 1978;.…”

The macroinvertebrate faunas of runs and riffles in three North Island streams were studied during February 1984. In all three streams, both habitats supported similar numbers of taxa and all species found in runs were also present in riffles. No more than two taxa in any one stream were exclusive to riffles, and of these, only the trichopteran Costachorema xanthoptera was exclusive to that habitat whenever it was found. In two of the streams (Rangitukia and Waitakaruru), the mean total densities of macroinvertebrates supported by runs and riffles were not significantly different. However, in Kiripaka Stream, higher total densities were found in riffles than in runs. Most of the taxa (63-68%) in each stream had similar densities in runs and riffles, but some (20-30%) were more abundant in riffles and a few (6-12%) were more abundant in runs. Of the nine major taxonomic groups recorded, only Ephemeroptera had consistently higher relative abundances in riffles than runs, whereas Gastropoda and Amphipoda had consistently higher relative abundances in runs. The distribution and abundance of macroinvertebrates are discussed in relation to environmental and biotic factors. The relevance of the data to invertebrate sampling programmes is also discussed.

“…It is likely that new species were formed by adaptation to new alpine habitat types during the rapid uplift of the Southern Alps 3-5 Ma (Arensburger et al 2004). Similar patterns with hotspots of local endemics are found among the alpine stoneflies (McLellan 1977;McCulloch et al 2010). The Lyperobius or 'speargrass' weevils are predominantly found in higher montane, subalpine and alpine grasslands, or herbfields and rocky habitats in the South Island (Craw 1999).…”

Alpine zones are threatened globally by invasive species, hunting, and habitat loss caused by fire, anthropogenic development and climate change. These global threats are pertinent in New Zealand, with the least understood pressure being the potential impacts of introduced mammalian predators, the focus of this review. In New Zealand, alpine zones include an extensive suite of cold climate ecosystems covering c. 11% of the land mass. They support rich communities of indigenous invertebrates, lizards, fish, and birds. Many taxa are obligate alpine dwellers, though there is uncertainty about the extent to which distributions of some species are relicts of wider historical ranges. The impacts of introduced mammalian predators are well described in many New Zealand ecosystems, though little is known about the impacts of these predators on alpine fauna. Here we review the importance of alpine habitats for indigenous fauna and the impacts of introduced mammalian predators; and develop a conceptual model explaining threat interactions. Most evidence for predation is anecdotal or comes from studies of species with wider ranges and at lower altitudes. Nevertheless, at least ten introduced predator species have been confirmed as frequent predators of native alpine species, particularly among birds and invertebrates. In the case of the endangered takahe (Porphyrio hochstetteri) and rock wren (Xenicus gilviventris), stoats (Mustela erminea) are primary predators, which are likely to be impacting significantly on population viability. We also document records of mammalian predation on alpine lizards and freshwater fish. While the precise impacts on the long-term viability of threatened species have not been evaluated, anecdotal evidence suggests that predation by mammals is a serious threat, warranting predator control. Future research should focus on predicting when and where mammalian predators impact on populations of indigenous fauna, furthering our understanding of the alpine predator guild particularly through adaptive management experiments, and exploring interactions with other threats.

Zelandobius edensis n. sp. is described from a spring-fed creek in the headwaters of the Rangitata River catchment, South Canterbury, New Zealand. Adult males exhibit varying degrees of brachyptery and the only female collected also had short wings. Larvae are easily identified by their covering of long translucent hairs not found in other members of the Zelandobius confususgroup. The link between adult and nymph was confirmed by comparing 600-base-pair sequences of the mitochondrial gene, cytochrome c oxidase 1. Observations suggest the life cycle may be strongly synchronised by temperature constraints on nymphal growth and development, and/or a short season suitable for feeding and reproduction by the terrestrial adults.
