Annual survival of Sparrowhawks Accipiter nisus breeding in three areas of Britain
Read more of: Annual survival of Sparrowhawks Accipiter nisus breeding in three areas of BritainAnnual survival of breeding female Sparrowhawks Accipiter nisus was estimated by a capture-recapture procedure in three different areas, Eskdale and Annandale in southern Scotland and Rockingham Forest in east-central England.

Measurements of seasonal rates and annual budgets of organic carbon fluxes in an Antarctic coastal environment at Signy Island, South Orkney Islands, suggest a broader balance between production and decomposition
Read more of: Measurements of seasonal rates and annual budgets of organic carbon fluxes in an Antarctic coastal environment at Signy Island, South Orkney Islands, suggest a broader balance between production and decompositionWe report here the first comprehensive seasonal study of benthic microbial activity in an Antarctic coastal environment. Measurements were made from December 1990 to February 1992 of oxygen uptake and […]

Evidence for winter/spring denitrification of the stratosphere in the nitrate record of Antarctic firn cores
Read more of: Evidence for winter/spring denitrification of the stratosphere in the nitrate record of Antarctic firn coresA firn core from within the polar vortex in the Weddell Sea sector of Antarctica shows nitrate peaks that occur in the spring or early summer. They are far less […]

Plasma flow bursts in the nightside auroral zone ionosphere and their relation to geomagnetic activity
Read more of: Plasma flow bursts in the nightside auroral zone ionosphere and their relation to geomagnetic activityWe examine the nature of flows in the nightside auroral zone ionosphere and their relationship with concurrent geomagnetic activity by studying a three-hour interval of ground-based radar, magnetometer array and […]

Dielectric properties of frozen clay and silt soils
Read more of: Dielectric properties of frozen clay and silt soilsThe dielectric properties of a clay and a silt soil have been studied at low water saturations at temperatures between −100°C and −15°C. The frequency range of the study (20 […]

Dielectric properties of ice containing acid and salt impurity at microwave and low frequencies
Read more of: Dielectric properties of ice containing acid and salt impurity at microwave and low frequenciesWe compare the microwave and low-frequency (LF) dielectric conductivity of natural and artificial ice as a function of impurity concentration and temperature. We find a linear dependence of conductivity on […]
