Global convection mapping using line-of-sight Doppler velocity data from the Super Dual Auroral Radar Network (SuperDARN) is now an accepted method of imaging high-latitude ionospheric convection. This mapping process requires […]
Recent work has suggested that in highly correlated systems, such as sandpiles, turbulent fluids, ignited trees in forest fires and magnetization in a ferromagnet close to a critical point, the […]
Cretaceous radiation of angiosperms from low to high palaeolatitudes, coupled with the break-up of Gondwana, played a major role in establishing and maintaining biogeographic patterns across the southern hemisphere. Uncertainties […]
Silicic volcanic rocks are associated with most, if not all, continental flood basalt provinces and volcanic rifted margins, where they can form substantial parts of the eruptive stratigraphy and have […]
Oxygen consumption and ammonia excretion of the Antarctic fish Notothenia corikeps (18.4 cm L-F) increased respectively two and fourfold above fasting levels 24 h after feeding with a single meal […]
1. The oceanography of the South Georgia region is principally that of the Southern Ocean rather than the South Atlantic. A combination of factors, including advection, local bathymetry and high […]
1. Estimating food consumption is central to defining the ecological role of marine predators. This study developed an algorithm for synthesizing information about physiology, metabolism, growth, diet, life history and […]
Four case studies are used to examine the relationships of water, ice nucleators and desiccation in the cold survival of invertebrates and the viability of frozen plant material: the freeze […]
1. The food consumption of an animal. both at the individual and the population level, is an essential component for assessing the impact of that animal on its ecosystem. As […]
A series of measurements were taken from 50 random examples of the arborescent sponges Raspailia rainosa and Stelligera stuposa at a number of sites and depths at Lough Hyne, Co. […]
