Unexpected absence of island endemics: Long-distance dispersal in higher latitude sub-Antarctic Siphonaria (Gastropoda: Euthyneura) species
Read more of: Unexpected absence of island endemics: Long-distance dispersal in higher latitude sub-Antarctic Siphonaria (Gastropoda: Euthyneura) speciesAim We assess biogeographical patterns, population structure and the range of species in the pulmonate genus Siphonaria across the sub‐Antarctic. We hypothesized that locally endemic cryptic species will be found […]

Analysis of physical and biogeochemical control mechanisms on summertime surface carbonate system variability in the western Ross Sea (Antarctica) using in situ and satellite data
Read more of: Analysis of physical and biogeochemical control mechanisms on summertime surface carbonate system variability in the western Ross Sea (Antarctica) using in situ and satellite dataIn this study, carbonate system properties were measured in the western Ross Sea (Antarctica) over the 2005–2006 and 2011–2012 austral summers with the aim of analysing their sensitivity to physical […]

Snow algae communities in Antarctica – metabolic and taxonomic composition
Read more of: Snow algae communities in Antarctica – metabolic and taxonomic compositionSnow algae are found in snowfields across cold regions of the planet, forming highly visible red and green patches below and on the snow surface. In Antarctica, they contribute significantly […]

Prospects for metazoan life in sub-glacial Antarctic lakes: the most extreme life on Earth?
Read more of: Prospects for metazoan life in sub-glacial Antarctic lakes: the most extreme life on Earth?About 400 subglacial lakes are known from Antarctica. The question of whether life unique of subglacial lakes exists has been paramount since their discovery. Despite frequent evidence of microbial life […]

Experimental validation of in silico predicted RAD locus frequencies using genomic resources and short read data from a model marine mammal
Read more of: Experimental validation of in silico predicted RAD locus frequencies using genomic resources and short read data from a model marine mammalBackground Restriction site-associated DNA sequencing (RADseq) has revolutionized the study of wild organisms by allowing cost-effective genotyping of thousands of loci. However, for species lacking reference genomes, it can be […]

Krill (Euphausia superba) distribution contracts southward during rapid regional warming
Read more of: Krill (Euphausia superba) distribution contracts southward during rapid regional warmingHigh-latitude ecosystems are among the fastest warming on the planet1. Polar species may be sensitive to warming and ice loss, but data are scarce and evidence is conflicting2,3,4. Here, we […]

Current logistical capacity is sufficient to deliver the implementation and management of a representative Antarctic protected area system
Read more of: Current logistical capacity is sufficient to deliver the implementation and management of a representative Antarctic protected area systemAntarctica’s terrestrial ecosystems are vulnerable to impacts resulting from climate change and local human activities. The Antarctic Treaty System (ATS) provides for the designation of protected areas through the Protocol […]
