Wayne Vogler and Nikki Owen recently published their paper 'Grader grass (Themeda quadrivalvis): changing savannah ecosystems' in Proceedings of the 16th Australian Weeds Conference. Grader grass is an invasive exotic 'high biomass' grass from India that is increasing its distribution in northern Australia. It is unpalatable and can dominate ecosystems, thereby decreasing grazing animal production, degrading conservation areas and increasing fire intensity and hazard. They studied aspects of its biology at a field site in north Queensland where the initial biomass of the grass layer was found to be 70% grader grass. Grader grass also produced 80% of the seed input into this ecosystem during the first growing season. These factors, in combination with a large viable seed bank and rapid germination at the start of the wet season, demonstrate the potential of grader grass to dominate and degrade the savannah ecosystems of northern Australia.

Tunneling magnetoresistance (TMR) in Ga(0.9)2Mn(0.08)As/Al-O/Co40Fe40B20 trilayer hybrid structure as a function of temperature from 10 to 50 K with magnetic field vertical bar H vertical bar <= 2000 Oe has been studied. TMR ratio of 1.6% at low fields at 10 K was achieved with the applied current of 1 mu A. The behavior of junction resistance was well explained by the tunneling resistance across the barrier. Strong bias dependences of magnetoresistance and junction resistance were presented. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3068418]
