Two new derivatives of a recently-reported class of irregular diterpene have been discovered in New Zealand species of the Apiaceae family. 16-Acetoxyanisotomenoic acid (8) (3,3a,4,4-tetramethyl-3-{(Z)-5-acetoxy-4-methyl-3-pentenyl}-2,3,3a,4,5,6-hexahydro-1H-2-indenecarboxylic acid) and anisotomene-1,12-diol (11) (3,3a,4,4-tetramethyl-3-(2-hydroxy-4-methyl-3-pentenyl)-2,3,3a,4,5,6-hexahydro-1H-2-indenyl) methanol) have been obtained from the sub-alpine plants, Anisotome flexuosa and A. haastii respectively. 13 C nuclear magnetic esonance (n.m.r.) spectra of the anisotomene derivatives are complicated by line broadening. Molecular modelling of anisotomenoic acid (1) and anisotomenol (2) suggests that this is due to conformational exchange in the highly substituted bicyclo [4,3,0] non-1-ene ring system.

Kuschelysiusnew genus is described for four species, K. hollowayaenew species, K. durusnew species, K. verbalisnew species and K. nitensnew species, which are found in alpine regions along the length of the South Island of New Zealand. The genus most closely resembles members of the genus Eugnomus but is distinguished from them by the presence of a small pair of post-ocular tubercles and by having appressed scales on the dorsal surfaces. Some members of Kuschelysius appear to be flight-capable with well-developed hindwings, while others have reduced hindwings and are presumably flightless. Many specimens have been collected from the flowers of Dracophyllum traversii, Celmisia and other alpine plants, and the guts of examined specimens contained pollen. We hypothesise that the species of Kuschelysius are pollinators of the New Zealand alpine flora.

Our collaboration involves groups in Denmark, the U.S.A. Spain and of course New Zealand. Combining ground-based and satellite (IUEandHST) observations we aim to determine accurate and precise stellar fundamental parameters for the components of Magellanic Cloud Eclipsing Binaries as well as the distances to these systems and hence the parent galaxies themselves. This poster presents our latest progress.

The Type I simple cold block device was described by Bullivant and Ames in 1966 and represented the product of the first successful effort to simplify the equipment required to do sophisticated freeze-cleave techniques. Bullivant, Weinstein and Someda described the Type II device which is a modification of the Type I device and was developed as a collaborative effort at the Massachusetts General Hospital and the University of Auckland, New Zealand. The modifications reduced specimen contamination and provided controlled specimen warming for heat-etching of fracture faces. We have now tested the Mass. General Hospital version of the Type II device (called the “Type II-MGH device”) on a wide variety of biological specimens and have established temperature and pressure curves for routine heat-etching with the device.
