The Malvernian igneous complex of the Malvern Hills consists mainlyof plutonic rocks and their locally deformed equivalents. The igneous rocks are calc-alkaline and range from ultra mafic diorite to granite […]
Peripheral blood and haemopoietic tissues of spleen and kidney of the icefish, Chaenocephalus aceratus were examined using LM and EM techniques. The peripheral blood contained cellular elements from all the […]
(1) Two superficially similar chalk grasslands in the Breckland of East Anglia provided very different habitats for the abundant terrestrial isopod Armadillidium vulgare (Latreille). At Lakenheath Warren the site was […]
Background. The study of altitudinal gradients provides insights about species diversity, distribution patterns and related drivers. The Magellanic sub-Antarctic ecoregion has a steep elevational gradient, peaking at around 1,000 m […]
In this article, we analyze the impacts of climate change on Antarctic marine ecosystems. Observations demonstrate large-scale changes in the physical variables and circulation of the Southern Ocean driven by […]
Antarctic krill, Euphausia superba, have a circumpolar distribution but are concentrated within the south-west Atlantic sector, where they support a unique food web and a commercial fishery. Within this sector, […]
The Utah State University (USU) Advanced Mesospheric Temperature Mapper (AMTM) was deployed at the Amundsen‐Scott South Pole Station in 2010 to measure OH temperature at ~87 km as part of […]
In this paper, we provide a comprehensive overview of the state-of-knowledge of dust flux and variability in time and space in different sectors of East Antarctica during the Holocene. By […]
Seasonal variations in temperature and moisture in moss peat were monitored in the field at Signy Island, Antarctica. When simulated in intact peat cores in vitro after frozen storage, these […]
Marine planktonic primary production was studied in Borge Bay, Signy Island, the Antarctic, during the period January 1972–February 1974. Productivity was measured in situ by the radiocarbon uptake method. In […]
