The Impact

Exploited marine ecosystems are a common feature of the modern world and area closures (marine reserves; MRs) have been suggested from both conservation and fishery management perspectives as a technique to rebuild over-fished populations. MRs provide an interesting experimental treatment where humans are excluded from resource harvesting. In the absence of exploitation, marine species have been observed to return to levels of abundance similar to historic accounts of virgin biomass (biomass under an exploitation level of 0). This thesis investigates the impact and potential of MRs in both New Zealand and Chile for achieving conservation and fishery management goals through the use of underwater observation, historic information, fishers’ ecological knowledge (FEK), bioeconomic fishery modeling and ecosystem modeling ... Overall, this thesis has investigated the effects of human coastal resource use in New Zealand and Chile from social, economic and ecological perspectives through the use of different techniques by synthesising both quantitative and qualitative information sources. MRs are a valuable tool from conservation, management and scientific perspectives as they can rebuild overexploited stocks and return the ecosystem to a more historic state. MRs also provide an understanding of the interaction between coastal resource use and ecosystem-wide changes, which is a crucial element for ecosystem-based management. This thesis has illustrated the importance of comparing present stock biomasses to historic baselines to understand the impacts of exploitation of coastal resources on marine ecosystems.

Organic Source

Zinc supplementation in rabbit diet favours deposition of this mineral in meat and, therefore, contributes to satisfying the daily requirements of Zn in humans that consume it. A trial was conducted to study the effect of two sources (ZnSO4 and Zn-methionate) and two concentrations of Zn, along with a control (without Zn supplementation), on weight gain, meat quality and muscle retention in New Zealand White (NZW) rabbits during fattening stage. Treatments were randomly assigned to 100 NZW rabbits 40 days old, in a completely randomised experimental design using a factorial arrangement of treatments (2×2+control). The experimental period was 30 d. In each experimental treatment, weight gain, feed consumption and meat quality were recorded, as well as the retention of Zn in serum, liver, loin and hind leg. Results showed no differences (P>0.05) in weight gain and food consumption, which can be attributed to diet-added Zn sources (ZnSO4 and Zn-methionate). Food conversion was better with the organic source at the highest concentration (P<0.05). Regarding meat quality, no differences were found (P>0.05) in hind legs for source effect and Zn concentration, while in loin, differences (P=0.02) were found in the colour parameter of L* and B* when the organic source of Zn (Zn-methionate) was supplied. Most retention of Zn on the loin occurred when a concentration of 25 mg Zn kg–1 of Zn-methionate was added, which could be important to provide larger amounts of Zn for human consumption.

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.

New Zealand White Rabbits

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.
