Recent studies have been equivocal in determining whether long-lived seabirds are able to respond to chick nutritional status and regulate provisioning rates accordingly. With some exceptions, albatrosses and petrels that […]
Vlasov simulations of the current-driven ion-acoustic instability produced in Maxwellian and non-Maxwellian (Lorentzian, kappa = 2) electron-ion plasma with number density 7 x 10(6) cm(-3), reduced mass ratio m(i)/m(e) = […]
Increasingly, output from numerical weather prediction (NWP) models is being used for real-time weather forecasts for the Antarctic and for Antarctic-related climate diagnostics studies. Evidence is presented that indicates that […]
The trend towards large size in marine animals with latitude, and the existence of giant marine species in polar regions have long been recognized, but remained enigmatic until a recent […]
The biodiversity of the pelagic bacterioplankton community of a maritime Antarctic freshwater lake was examined by cultivation-dependent and cultivation-independent techniques to determine predominant bacterioplankton populations present. The culture-dependent techniques used […]
This review seeks to highlight the potential importance of viruses in Antarctic ecosystems and describe the limited scope of Antarctic virus studies to date, including studies of marine, terrestrial and […]
The bacterioplankton community structure in Moss Lake, a maritime Antarctic oligotrophic lake, was determined with vertical depth in the water column, during the ice-free period on Signy Island in the […]
A -190-nT negative bay in the geomagnetic X component measured at Macquarie Island (-65degreesA) showed that an ionospheric substorm occurred during 09:58 to 11:10 UT on 27 February 2000. Signatures […]
Small outcrops of the basement of the Deseado Massif, consisting of weathered, altered granitoids and their metasedimentary host rocks, were dated by the U-Pb zircon method using thermal ionization mass […]
Rb-Sr and Sm-Nd whole-rock data for granitoids and orthogneisses from the western part of the Sierras Septentrionales of the southern Buenos Aires province yield an errorchron of 2009 +/- 71 […]
Schistidium is the richest moss genus in the Antarctic consisting of twelve species, one of which, S. deceptionense Ochyra, Bednarek-Ochyra, & Lewis Smith, is here described as new to science […]
