Metabolic rate and body size: a new view on the 'surface law' for basic metabolic rate.

In larger animals a considerable part of the total body mass (e.g. body water, dissolved substances, mineral and organic deposits) does not consume significant amounts of oxygen.

Presence and significance of lithium in the brown shrimp, Crangon crangon (L.).

1. In female (non-ovigerous and ovigerous) brown shrimps, Crangon crangon, whole animal lithium levels are about 20% higher than in males, which indicates that lithium has a special function in the female reproductive system. 2.

Some aspects of element turnover in living organism.

The net uptake and loss of any element by a living organism can be described as the quotient of the total amount of the element, present in the organism, and its residence time in the organism. Theoretically it can be derived that the residence time tau i, equals Vi1-b/kappa, in which b, the morphometric coefficient, is related to size and shape of the organism (volume Vi); kappa, the turnover coefficient, is related to its metabolic activity. The net uptake or excretion, phi i, of an element then follows from phi = kappa Ci Vib, Ci being the (average, whole animal) concentration of the element.
