(1) Disease is often viewed as a density-dependent factor expected to limit population numbers, but field evidence from mammals is generally lacking. (2) Mandibular swellings in reindeer on South Georgia […]
During 4- to 8-day periods at sea, half of 2595 dives of three king penguins were more than 50 meters and two dives exceeded 240 meters. The at-sea metabolic rate, […]
Bryum cf. algens Card, was collected by SCUBA divers from 9-31 m in the benthos of perennially ice-covered Lake Vanda (77°32′S, 161°35′E), Wright Valley, southern Victoria Land, Antarctica. It occurred […]
Terrestrial myriametric radiation (non-thermal continuum) observed by the GEOS 1 spacecraft is used to determine the radial profile of plasma density at the equatorial plasmapause. The method utilises the properties […]
We present a shear wave model of the West Antarctic upper mantle to ∼200 km depth with enhanced regional resolution from the 2016-2018 UK Antarctic Seismic Network. The model is […]
1. The oxygen consumption of four species of inshore gastropods from Signy Island, Antarctica was measured at −1.7 and +0.5°C in seawater. The limpet Nacella concinna (Strebel) showed a decrease […]
The heat and ice balances of a temperate sub-Antarctic cirque glacier were measured through the 1973–74 melt season at an altitude midway between the climatic firn limit and the snout. […]
