2. Comparison of the cold hardiness of two larval Lepidoptera (Noctuidae)

   Diapause larvae of the European corn borer (Ostrinia nubilalis (Hubn.)) and the related Mediterranean noctuid Sesamia cretica Led. possess sufficient supercooling ability to avoid freezing over their normal environmental temperature […]

3. Known, new and probable Snow Petrel breeding locations in the Ross Dependency and Marie Byrd Land

   Snow Petrels (Pagodroma nivea) breed circurnpolarly in Antarctica. Watson et al. (1971), Harper et al. (1984) and Marchant & Higgins (1990) list breeding sites in the Ross Dependency (160°E-150°W) and […]

4. Reproductive biology of caridean decapods from the Weddell Sea

   Data on reproductive biology are presented for five benthic caridean shrimps from the high Antarctic (Chorismus antarcticus, Notocrangon antarcticus, Nematocarcinus lanceopes, Lebbeus antarcticus and Eualus kinzeri). The first three species […]

5. Precipitation nitrogen at maritime Signy Island and continental Cape Bird, Antarctica

   The mineral nitrogen (NH4-N + NO3-N) in precipitation occurring at continental and maritime Antarctic sites has been determined. Precipitation at sites remote from animal activity contained much less mineral N […]

6. Retention of precipitation nitrogen by Antarctic mosses, lichens and fellfield soils

   Retention of mineral elements in precipitation by mosses and lichens involving ion exchange and chelation mechanisms is a source of nutrients for these biota growing on rocks and nutrient poor […]

7. Glacier fluctuations on South Georgia during the 1970s and early 1980s

   South Georgia is a highly glacierized island with a range of glacier types including corrie, valley and tidewater ice bodies. Glaciologically, it occupies a strategic location between South America and […]

8. Dynamics of plasma nutrients and metabolites in moulting macaroni (Eud yptes chrysolophus) and gentoo (Pygoscelis papua) penguins

   1.1. Dynamics of plasma nutrients and metabolites in moulting macaroni (Eudyptes chrysolophus) and gentoo (Pygoscelis papua) penguins were studied.2.2. The late moult macaroni and gentoo penguins had significantly elevated levels […]

9. How unstable is the West Antarctic ice sheet?

   In the late 1970s, many people still thought that a cooling trend in the Northern Hemisphere heralded the next ice age. But some were already claiming that rising atmospheric CO2 […]
