The sea ice fraction in the interior of the pack, especially in winter, is important for climate studies and for validation of sea ice models. When ice concentration is high, […]
No Lepidoptera (butterflies and moths) are known to be residents of South Georgia. This paper presents new records of three lepidopterans on the island. Two, Agrotis ipsilon (Noctuidae) and Plutella […]
We describe a terrestrial faunal community including only Tardigrada and Rotifera, present on inland nunataks of Ellsworth Land, Antarctica (∼75°–77° S, 70°–73° W). The fauna is exceptional in its simplicity, […]
Many phyla of marine invertebrates are difficult to identify using conventional morphological taxonomy. Larvae of a wider set of phyla are also difficult to identify as a result of conservation […]
The continued retreat of ice shelves on the Antarctic Peninsula has been widely attributed to recent atmospheric warming, but there is little published work describing changes in glacier margin positions. […]
Background Animal mitochondrial genomes are physically separate from the much larger nuclear genomes and have proven useful both for phylogenetic studies and for understanding genome evolution. Within the phylum Arthropoda […]
The biologically damaging solar ultraviolet (UV) radiation (quantified by the DNA-weighted dose) reaches the martian surface in extremely high levels. Searching for potentially habitable UV-protected environments on Mars, we considered […]
The dynamic behaviour of the outer electron radiation belt makes this area of geo-space a candidate for the concept of self-organized criticality. It is shown here that frequency distributions of […]
Although albatrosses are paradigms of oceanic specialization, their foraging areas and migration routes when not breeding remain essentially unknown. Our continuous remote tracking of 22 adult gray-headed albatrosses for over […]
Here we present an operational method to improve accuracy and information content of ground-based measurements of stratospheric NO2. The motive is to improve the investigation of trends in NO2, and […]
We describe in situ observations on nesting by the Scotia Sea (or blackfin) icefish Chaenocephalus aceratus (Lönnberg) that constitute the first substantive evidence of egg brooding and parental care by […]
Simultaneous iron resonance lidar density profiles, OH intensity images and MF-radar wind measurements have been used to determine the horizontal and vertical components of high-frequency (
