Grazing Behaviour

The effect of contrasting white clover contents on diet selection by grazing sheep provides an insight into grazing behaviour mechanisms. When sheep have a choice between ‘strips’ containing either 70% white clover or 100% grass they consistently choose to graze the former. When clover is intermingled with grass in normal sheep-grazed swards evidence for selective grazing is less clear. The objectives of this experiment were, firstly, to define the pattern of discrimination in response to variation in the contrast in clover content between alternative swards. And, secondly, to test whether the pattern is affected by the mean clover content about which the range is established.The ‘base’ levels of clover content: 30 and 60% together with 7 ‘contrast’ levels from -30 to +30% of ‘base’ level were planned. Swards of equal content were included as controls. Thus the 30% base was contrasted with 0, 10, 20, 30, 40, 50 and 60%; and the 60% base with 30, 40, 50, 60, 70, 80 and 90% white clover. Each combination of treatments was repeated at two nitrogen levels: C and 30 kg N/ha and the whole replicated twice. The experimental area was at Grasslands Division, Palmerston North, New Zealand. The pasture comprised well-established Ruanui ryegrass - Huia white clover with some weed species. Fifty-six plots (5.6 x 3.5 m), each containing 2 ‘contrast’ areas at 2.8 x 3.5 m were sprayed with different herbicides on 29 July 1983 to achieve the above contrasts.

Sissano Lagoon

A Mw 7.1 earthquake off the north coast of New Guinea, generated a locally very destructive tsunami at 08:49 17th July 1998 UTC (6:49 PM local time). More than 2189 people died, and no structures were left standing along 19 km of coast. A reconnaissance team from the N.Z. Society for Earthquake Engineering visited the area a month after the event. Over three days, they examined effects of the tsunami on structures and landforms, measured profiles and sampled deposits. A fast moving wall of sand-laden water left fishing nets and other detritus in trees up to 17.5 m above sea level. Concrete was stripped to the reinforcing, and some trees were ripped out and carried more than a kilometre. The team saw evidence of new subsidence of -300-400 mm on the landward side of the spit fronting Sissano Lagoon. The site is in an active sedimentary basin, the Aitape Trough with 4,500-m thickness of Neogene sediments, between the Bewani fault zone and the Wewak Trench. The area may have subsided 3 times this century. In situ stumps of drowned trees in the lagoon record one of the earlier events. The low-angle Harvard University CMT solution (Mw 7.1, depth -6.0 km, -10° landward dip on fault with northward displacement) is consistent with the tectonic setting and pattern of aftershocks. Elastic modelling of the energy release with -2 m horizontal displacement over 600 km2, suggests -400 mm subsidence (landward) and -600 mm uplift (seaward in >3 km water depth). The team suggests that convergent flow of the displaced water into the area of subsidence focused wave energy on the coast and generated the locally very high wave. The spit fronting Sissano Lagoon is unsafe for habitation. There is potential for coseismic coastal subsidence to focus tsunami in other areas with similar tectonic settings. This potential suggests that both eastern and western New Zealand coasts have a serious hazard from local tsunami that is presently underestimated for the western coastline because of the lack of historical occurrences.

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.

There are different methods and devices for the increase of the videosignal information in SEM. For example, with the help of special pure electronic [1] and opto-electronic [2] systems equipotential areas on the specimen surface in SEM were obtained. This report generalizes quantitative universal method for space distribution representation of research specimen parameter by contour equal signal lines. The method is based on principle of comparison of information signal value with the fixed levels.Transformation image system for obtaining equal signal lines maps was developed in two versions:1)In pure electronic system [3] it is necessary to compare signal U (see Fig.1-a), which gives potential distribution on specimen surface along each scanning line with fixed base level signals εifor obtaining quantitative equipotential information on solid state surface. The amplitude analyzer-comparator gives flare sport videopulses at any fixed coordinate and any instant time when initial signal U is equal to one of the base level signals ε.

This cytochemical study was designed to investigate early metabolic changes in the aortic wall that might lead to or accompany development of atherosclerotic plaques in rabbits. The hypothesis that the primary cellular alteration leading to plaque formation might be due to changes in either carbohydrate or lipid metabolism led to histochemical studies that showed elevation of G-6-Pase in atherosclerotic plaques of rabbit aorta. This observation initiated the present investigation to determine how early in plaque formation and in which cells this change could be observed.Male New Zealand white rabbits of approximately 2000 kg consumed normal diets or diets containing 0.25 or 1.0 gm of cholesterol per day for 10, 50 and 90 days. Aortas were injected jin situ with glutaraldehyde fixative and dissected out. The plaques were identified, isolated, minced and fixed for not more than 10 minutes. Incubation and postfixation proceeded as described by Leskes and co-workers.
