  This is the first published invertebrate survey focusing on a low-altitude shrubland community in New Zealand. Invertebrates were collected from a remnant native shrubland (450 m) protected by the Brookdale Conservation Covenant, Rock and Pillar Range, Otago, New Zealand in late summer/autumn 1999. Sampling was carried out by beating 30 randomly chosen shrubs of each of two native species: Olearia bullata H. D. Wilson & Garnock-Jones (Asteraceae) and Coprosma propinqua A. Cunn. (Rubiaceae). Fifty pitfall traps were also set under the same shrubs and on nearby open patches of exotic grassland. Three Phyla, six Classes, 25 Orders and approximately 280 species were recorded. An annotated list of taxa is presented, and plant/host associations plus other observations on the fauna are discussed. Approximately 90% of the identified species were endemic, emphasising the importance of such remnant habitats for the protection of New Zealand's biodiversity.

• AgF-mediated Hofmann-type reaction of N-tosyl cyclic imides with silicate esters

  A facile and efficient AgF-mediated Hofmann-type reaction of N-tosyl cyclic imides with silicate esters was developed. The N-tosyl cyclic imides undergo a Hofmann-type rearrangement/alkoxylation reaction in which the silicate ester acted as the alkoxy source. This reaction proceeds under simple and mild conditions to generate a series of anthranilic acid-derived carbamates in moderate to good yields
