The techniques for estimating hmF2 from M(3000)F2 are reviewed with particular stress put upon those in which the effects of underlying ionization are accounted for by a correction (ΔM) to […]
Water turnover rates were measured in gentoo and macaroni penguins breeding sympatrically on South Georgia Island. At the time of this study, adult male macaronis were attending the nest while […]
The role of the sexes in incubation, their changes in body weight and associated energy costs were studied in the Wandering Albatross at South Georgia. Males incubate significantly more than […]
