Moult scores were collected from colour‐ringed individuals of known reproductive status of the two species of giant petrel, Macronectes halli and M. giganteus, at Bird Island, South Georgia between 1978–81. […]
The breeding biology and population dynamics of the two species of giant petrels, Macronectes halli and M. giganteus, were studied at Bird Island, South Georgia during 1978–81. The mean laying […]
During geomagnetic storms different partial pressure gradients in the auroral ionosphere may result in H+, He+, O+ and molecular ions drifting with different velocities along the Earth’s magnetic field line. […]
