Booroola Merino, Border Leicester and Collinsville Merino rams were joined in three successive years to Collinsville ewes and ewe progeny from all three groups were subsequently joined with Dorset Horn rams at Leeton Agricultural Research Station. When data were analysed for performance at up to five joinings and lambings, there were significant differences among the ewe groups in ovulation rat...

A great number of radioactive cesium were released into sea water after Fukushima Accident. We modified the Regional Oceanic Modelling System (ROMS) to reproduce the dispersion process of the cesium in oceans. The simulated water concentration was in good agreement with observation. In order to explore the nuclear impact of these contaminant in ocean, we established a food web model to calculat...

Groups of adult lactating Border Leicester cross Merino ewes which had lambed in the spring and had been milked mechanically after the lambs had been weaned at birth, were joined with Dorset Horn rams approximately 60 days after parturition. The ewes had been treated with progestogen sponges and pregnant mare’s serum gonadotrophrin (750 and 1500 I.U.) prior to the time of first or second expect...

Gary Brassington is first introducing this newsletter with a paper telling us about the international summer school for “observing, assimilating and forecasting the ocean” which will be held in Perth, Western Australia in 11-22 January 2010 (http://www.bom.gov.au/bluelink/summerschool/). The course curriculum will include topics covering the leading edge science in ocean observing systems, as w...
