Shrubland communities dominated by manuka (Leptospermum scoparium J. Forst. and G. Forst.) and kanuka (Kunzea ericoides var. ericoides ((A. Rich) J. Thompson) are widespread throughout New Zealand. They frequently colonise disturbed land surfaces and are important for erosion mitigation, and also for their capacity to act as a carbon (C) sink. We here investigate C and nitrogen (N) cycling in 3 stands (~26–56 years old) that had established on a repeatedly burned forest site on a Podzolic Orthic Pumice soil in the Turangi area, central North Island. For comparison, limited measurements of N cycling were also made at other manuka–kanuka sites on non-volcanic soils. Leaf N concentrations at the Turangi site were 11.8–13.9 g/kg, and lower than those at many of the other manuka–kanuka stands. Total annual litterfall and N content increased with stand age, as did total N concentrations in FH material and mineral soil (0–100 mm depth). Total C concentrations in mineral soil did not, however, differ significantly in the 3 stands. Levels of soil microbial C and N, rates of carbon dioxide production, and metabolic coefficients (qCO2 values) suggest C cycling could be fairly rapid at this site. In contrast, rates of net mineral-N and nitrate-N production were low to very low compared with those in similar pumice soils under angiosperm–conifer forests, and in the non-volcanic soils under other manuka–kanuka stands. Low N availability and tight N cycling at the Turangi site are thereby strongly suggested. No definitive explanation for the atypically low N availability at this site is apparent, although the possible effects of previous forest burnings may have been a contributing factor. The continued growth of these shrubs, nevertheless, shows they can compete successfully for the N that does become available through gross N mineralisation in the Turangi ecosystem.

The New Zealand fauna of Eriophyoidea (Acari: Prostigmata) is updated with a checklist. One new genus, six new species, three new combinations, one new record and some new distribution records of eriophyoid mites from New Zealand are described and illustrated, namely Disella rebeeveri sp. nov. on Kunzea ericoides (Myrtaceae); Cecidophyopsis hendersoni (Keifer, 1954), rec. nov. on Yucca glauca and Y. elephantipes (Agavaceae); Nameriophyes sapidae gen. nov. & sp. nov. on Rhopalostylis sapida (Palmae); Eriophyes bennetti sp. nov. on Fuchsia excorticata (Onagraceae); Eriophyes georgeae sp. nov. on Brachyglottis elaeagnifolia (Asteraceae); Aceria flynni sp. nov. on Kunzea ericoides (Myrtaceae); Aculops propinquae (Manson, 1984), comb. nov. on Coprosma propinqua (Rubiaceae); Aculus corynocarpi (Manson, 1984), comb. nov. on Corynocarpus laevigatus (Corynocarpaceae); Aculus heatherae (Manson, 1984), comb. nov. on Raukaua simplex (Araliaceae), Leptospermum scoparium (Myrtaceae) and Syzygium maire (Myrtaceae); Aculus lalithi sp. nov. on Melicope ternate (Rutaceae). A key to the New Zealand species of Eriophyes is provided.

Observations of wild plants and herbarium specimens suggest that hybridism is a feature of the Australasian Kunzea ericoides (Myrtaceae) complex. In this study 73 artificial cross combinations were attempted with New Zealand material of Leptospermum scoparium, five Kunzea species, two varieties and six informally recognised entities within the New Zealand K. ericoides complex. The results of these crosses are documented, and for five hybrids spanning the intergeneric, interspecific and intraspecific crosses attempted, we provide a more detailed assessment based on morphology, molecular (nrDNA and chloroplast) sequence variation, and genomic in situ hybridisation (GISH). This is the first time GISH has been used in the Myrtaceae. Hybrids were easily generated between the New Zealand members of the K. ericoides complex, but not between them and the Australian K. ericoides complex. We were unable to produce hybrids between the New Zealand K. ericoides complex and two more distantly related Australian species, K. baxteri and K. parvifolia. Intergeneric crosses between New Zealand plants of Leptospermum scoparium, Kunzea sinclairii and an informally recognised variant K. aff. ericoides (b) were successfully produced, but failed to flower. The molecular evidence and observations after GISH show that even when low levels of sequence divergence exist, genome differentiation, to different extents, can be observed. The results confirm some suspected New Zealand hybrid complexes. However, while hybrids were easily generated artificially, natural instances of hybridism appear to be largely confined to those habitats significantly disturbed since European settlement of both countries.
