A novel miniature confocal microscope/Raman spectrometer system for biomolecular analysis on future Mars missions after Antarctic trials
Read more of: A novel miniature confocal microscope/Raman spectrometer system for biomolecular analysis on future Mars missions after Antarctic trialsBiomolecules, such as the productive and protective pigments of photosynthetic organisms, are good biomarkers in extreme Antarctic deserts as analogues of early Mars. Laser Raman technology at long wavelengths which […]

Molecular evidence for genetic mixing of Arctic and Antarctic subpolar populations of planktonic foraminifers
Read more of: Molecular evidence for genetic mixing of Arctic and Antarctic subpolar populations of planktonic foraminifersBipolarity, the presence of a species in the high latitudes separated by a gap in distribution across the tropics, is a well-known pattern of global species distribution. But the question […]

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 […]
