Plankton patchiness and its effect on larger-scale productivity
Read more of: Plankton patchiness and its effect on larger-scale productivityWe investigate systematically the effect of small-scale biological and physical processes on the generation of plankton patchiness, and on the biological production averaged over scales much larger than those of […]

Regional variability of ice core dust composition and provenance in Greenland
Read more of: Regional variability of ice core dust composition and provenance in GreenlandMineralogical and isotopic composition (Sr and Nd) of six dust samples, obtained from six widely spread ice-coring sites in Greenland, were analyzed in order to investigate the regional geographic variability […]

Activity and dormancy in relation to body water and cold tolerance in a winter-active springtail (Collembola)
Read more of: Activity and dormancy in relation to body water and cold tolerance in a winter-active springtail (Collembola)Ceratophysella sigillata (Collembola, Hypogastruridae) has a life cycle which may extend for >2 years in a temperate climate. It exists in two main morphs, a winter-active morph and a summer-dormant […]

Water status and thermal analysis of alginate beads used in cryopreservation of plant germplasm
Read more of: Water status and thermal analysis of alginate beads used in cryopreservation of plant germplasmEncapsulation and dehydration techniques using alginate beads are used increasingly for the pre-treatment of various plant materials for cryopreservation to improve survival post-cryogenic storage. This study reports the effects of […]

Water or ice? – the challenge for invertebrate cold survival
Read more of: Water or ice? – the challenge for invertebrate cold survivalThe ecophysiology of cold tolerance in many terrestrial invertebrate animals is based on water and its activity at low temperatures, affecting cell, tissue and whole organism functions. The normal body […]
