Fatty acid composition as an indicator of carnivory in Antarctic krill,Euphausia superba
Read more of: Fatty acid composition as an indicator of carnivory in Antarctic krill,Euphausia superbaIn a previous study at South Georgia, carnivory was invoked as a cause of high polyunsaturated fatty acid (PUFA) content of Antarctic krill, Euphausia superba. To examine this, krill were […]

The nature and origin of taxonomic diversity gradients in marine bivalves
Read more of: The nature and origin of taxonomic diversity gradients in marine bivalvesBivalves have been fundamental in developing the understanding of large-scale biodiversity patterns in the marine realm. A new study based on 29 regional bivalve faunas indicates that both latitudinal and […]

Intrinsic and extrinsic controls on the diversification of the Bivalvia
Read more of: Intrinsic and extrinsic controls on the diversification of the BivalviaAt the present day the Class Bivalvia comprises some 8000 species, sub-divided into approximately 700 genera, 107 families, and 41 superfamilies (Morton, 1996, and references therein). It represents one of […]

Evolution of taxonomic diversity gradients in the marine realm: evidence from the composition of Recent bivalve faunas
Read more of: Evolution of taxonomic diversity gradients in the marine realm: evidence from the composition of Recent bivalve faunasA major new inventory of living marine Bivalvia (Mollusca) is based on 29 regional faunas. These again pick out strong latitudinal and longitudinal gradients in taxonomic diversity, but there are […]

The terrestrial biota of Charcot Island, eastern Bellingshausen Sea, Antarctica: an example of extreme isolation
Read more of: The terrestrial biota of Charcot Island, eastern Bellingshausen Sea, Antarctica: an example of extreme isolationThis paper documents the previously undescribed terrestrial fauna (mites, nematodes, tardigrades) and flora (liverworts, mosses and lichens) of Marion Nunataks, Charcot Island (69°45’S 075°15’W). Species diversity in all groups is […]

The flora of the South Sandwich Islands, with particular reference to the influence of geothermal heating
Read more of: The flora of the South Sandwich Islands, with particular reference to the influence of geothermal heatingAim To carry out as comprehensive a survey as practicable of the flora (higher plants, mosses, liverworts, lichens, basidiomycete fungi and diatoms) of the isolated, volcanically active, South Sandwich Islands […]

The terrestrial micro-arthropod fauna of the South Sandwich Islands
Read more of: The terrestrial micro-arthropod fauna of the South Sandwich IslandsThe South Sandwich Islands are an isolated maritime Antarctic volcanic island arc 550-600km south-east of South Georgia. The terrestrial biology of the islands, with emphasis on the unique habitats associated […]

Survival of freezing by free-living Antarctic soil nematodes
Read more of: Survival of freezing by free-living Antarctic soil nematodesFree-living microbivorous nematodes become numerically dominant in Antarctic terrestrial faunas as environmental conditions become more severe, while also reaching very high levels of abundance in moist, vegetated habitats. Nematodes have […]

Refining the risk of freezing mortality for Antarctic terrestrial microarthropods
Read more of: Refining the risk of freezing mortality for Antarctic terrestrial microarthropodsIn studies of three common, freezing susceptible, Antarctic microarthropods, the springtail Cryptopygus antarcticus and the mites Alaskozetes antarcticus and Halozetes belgicae, we report (i) the consequences on cold tolerance of […]
