Microplastics in Antarctic krill (Euphausia superba) from Antarctic region

Science of the Total Environment, 2023
Pollution of microplastics (MPs) has become a potential threat to Antarctic marine ecosystems. However, the occurrence of MPs in Antarctic krill (Euphausia superba), a keystone species in Antarctic ecosystems, remains unclear. In this study, the abundance and characteristics of MPs were examined in Antarctic krill samples (n = 437) collected from two ...

NAIL GROWTH IN ANTARCTIC REGIONS

Australasian Journal of Dermatology, 1983
SummaryFinger nail and great toe nail growth was observed in 42 subjects: 28 over 11 months of an expedition at an Antarctic Station and 14 over 10 months on a Sub‐antarctic island. The mean rates of finger nail growth were 109.8μm per day and 106.4 μm per day respectively, and great toe nail growth was approximately half the finger nail growth at both

THE GENUS MICROCOSTATUS IN THE ANTARCTIC REGION

Diatom Research, 2010
The genus Microcostatus was erected in 1998 by Johansen & Sray to accommodate a small number of tiny naviculoid species belonging to the former section Naviculae minusculae, characterized by the presence of the typical microcostae, a series of external transapical costae near the axial area, the possession of a simple raphe system and the lack of a ...

The Acarology of the Antarctic Regions

1965
In more than one sense both the Antarctic continent and the Sub-Antarctic islands are white spots on the map. The existence of such areas has always inspired men to enlarge our knowledge, and several expeditions have been equipped to explore the unknown lands of Antarctica.

The genus Stauroneis (Bacillariophyceae) in the Antarctic region

Journal of Biogeography, 2005
AbstractAim  To provide a detailed biogeography of the diatom genus Stauroneis in the Antarctic and sub‐Antarctic regions and to establish the biogeographical relationships between the different constituent locations to test the application of a precise and refined taxonomy in generating accurate polar biogeographies.Location  The Antarctic and sub ...
