How worms survive desiccation
While life requires water, many organisms, known as anhydrobiotes, can survive in the absence of water for extended periods of time. Although discovered 300 years ago, we know very little about the fascinating phenomenon of anhydrobiosis. In this paper, we summarize our previous findings on the desiccation tolerance of the Caenorhabditis elegans dauer larva. A special emphasis is given to the r...
متن کاملStability and Synthesis of Phospholipids during Desiccation and Rehydration of a Desiccation-Tolerant and a Desiccation-Intolerant Moss.
The fatty acid composition of the phospholipids from the desiccation-tolerant moss Tortula ruralis (Hedw.) Gaertn, Meyer and Scherb and the desiccation-intolerant moss Cratoneuron filicinum has been determined. No changes in composition occur in either moss as a consequence of rapid drying, but, after slow drying, there is a decline in some unsaturated fatty acids. Upon rehydration of T. rurali...
متن کاملExperimental Analysis of Desiccation Crack
A laboratory investigation on a scaled model of a landACT: l ti n a scaled o l f fill liner was conducted to provide data regarding the occurrence l i e e and extent of desiccation cracking of prototype liners. The crack t t of desi t e li rs. intensity factor, CIF, was introduced as a descriptor of the extent of t f , , as i tr as f the extent of surficial cracking. CIF is defmed as the rati...
متن کاملJunction formation during desiccation cracking.
In order to provide a sound physical basis for the understanding of the formation of desiccation crack networks, an experimental study is presented addressing junction formation. Focusing on junctions, basic features of the network determining the final pattern, provides an elemental approach and imparts conceptual clarity to the rather complicated problem of the evolution of crack patterns. Us...
متن کاملDesiccation tolerance in the moss Polytrichum formosum: physiological and fine-structural changes during desiccation and recovery.
BACKGROUND AND AIMS This study explores basic physiological features and time relations of recovery of photosynthetic activity and CO(2) uptake following rehydration of a desiccation-tolerant moss in relation to the full temporal sequence of cytological changes associated with recovery to the normal hydrated state. It seeks reconciliation of the apparently conflicting published physiological an...
