INTRODUCTION In a previous paper (Croghan, 19586) the very great osmo-regulating ability of Artemia has been described. It is clear that in concentrated media the animal must have very well-developed active mechanisms both for excreting NaCl and for taking up water to compensate for the passive movements of these substances into and out of the animal. The staining of localized parts of Crustace...
1. The patterns of myoplasmic water and solute regulation were examined in several species of marine decapod crustaceans acclimated to various salinities. Three osmoconformers (Callianassa cahformemsis, Cancer antennarius, Emerita analoga) and one weak osmoregulator {Pachygrapsus crassipes) were studied. 2. Although haemolymph water and solute activities varied with adaptational salinity in the...
Organisms across the tree of life use a variety of mechanisms to respond to stress-inducing fluctuations in osmotic conditions. Cellular response mechanisms and phenotypes associated with osmoadaptation also play important roles in bacterial virulence, human health, agricultural production and many other biological systems. To improve understanding of osmoadaptive strategies, we have generated ...
Cells are continuously sensing and processing information from their environments and responding to it in sensible ways. The communication networks on which such information is handled often consist of systems of chemical reactions, such as signaling pathways or metabolic networks. This thesis studies the dynamics of systems of chemical reactions in the context of biological cells. The first pa...
