Molecular identification of unusual pathogenic yeast isolates by large ribosomal subunit gene sequencing: 2 years of experience at the United Kingdom Mycology Reference Laboratory
Read more of: Molecular identification of unusual pathogenic yeast isolates by large ribosomal subunit gene sequencing: 2 years of experience at the United Kingdom Mycology Reference LaboratoryRapid identification of yeast isolates from clinical samples is particularly important given their innately variable antifungal susceptibility profiles. We present here an analysis of the utility of PCR amplification and […]

Is the Scotia Sea a centre of Antarctic marine diversification? Some evidence of cryptic speciation in the circum-Antarctic bivalve Lissarca notorcadensis (Arcoidea: Philobryidae)
Read more of: Is the Scotia Sea a centre of Antarctic marine diversification? Some evidence of cryptic speciation in the circum-Antarctic bivalve Lissarca notorcadensis (Arcoidea: Philobryidae)The bivalve Lissarca notorcadensis is one of the most abundant species in Antarctic waters and has colonised the entire Antarctic shelf and Scotia Sea Islands. Its brooding reproduction, low dispersal […]

Growth in the slow lane: protein metabolism in the Antarctic limpet Nacella concinna (Strebel 1908)
Read more of: Growth in the slow lane: protein metabolism in the Antarctic limpet Nacella concinna (Strebel 1908)Growth rates in Antarctic ectotherms are generally considered to be low in comparison to temperate and tropical species. Food consumption plays a major role in determining animal growth rates, but […]

Diversity and species distribution of polychaetes, isopods and bivalves in the Atlantic sector of the deep Southern Ocean
Read more of: Diversity and species distribution of polychaetes, isopods and bivalves in the Atlantic sector of the deep Southern OceanWe examined deep-sea benthic data on polychaetes, isopods and bivalves from the Atlantic sector of the Southern Ocean. Samples were taken during the expeditions EASIZ II (1998), ANDEEP I and […]

Interplanetary transfer of photosynthesis: an experimental demonstration of a selective dispersal filter in planetary island biogeography
Read more of: Interplanetary transfer of photosynthesis: an experimental demonstration of a selective dispersal filter in planetary island biogeographyWe launched a cryptoendolithic habitat, made of a gneissic impactite inoculated with Chroococcidiopsis sp., into Earth orbit. After orbiting the Earth for 16 days, the rock entered the Earth’s atmosphere […]

Isolation of diverse viable fungi from the larvae of the introduced chironomid Eretmoptera murphyi on Signy Island
Read more of: Isolation of diverse viable fungi from the larvae of the introduced chironomid Eretmoptera murphyi on Signy IslandThe chironimid midge Eretmoptera murphyi has been introduced to Signy Island and has since become established at a single site. Viable propagules of a diverse range of micro-fungi were recovered […]

External nutrient inputs into terrestrial ecosystems of the Falkland Islands and the Maritime Antarctic region
Read more of: External nutrient inputs into terrestrial ecosystems of the Falkland Islands and the Maritime Antarctic regionAntarctic terrestrial ecosystems are nutrient-poor and depend for their functioning in part on external nutrients. However, little is known about the relative importance of various sources. We measured external mineral […]

Evidence for a CO increase in the SH during the 20th century based on firn air samples from Berkner Island, Antarctica
Read more of: Evidence for a CO increase in the SH during the 20th century based on firn air samples from Berkner Island, AntarcticaTrends of carbon monoxide (CO) for the past 100 years are reported as derived from Antarctic firn drilling expeditions. Only one of 3 campaigns provided high quality results. The trend […]

Using likelihood to test for Lévy flight search patterns and for general power-law distributions in nature
Read more of: Using likelihood to test for Lévy flight search patterns and for general power-law distributions in nature1. Ecologists are obtaining ever-increasing amounts of data concerning animal movement. A movement strategy that has been concluded for a broad variety of animals is that of Lévy flights, which […]
