This publication should still entice a person attracted to microbial ecology, geobiology, biogeochemistry and the background of technological know-how. The translated textual content is followed by way of wide footnotes and through an Editor’s precis on the finish of every bankruptcy putting Baas Becking’s writing within the context of recent advancements within the box

Example text

Lakes of the second order have an incompletely developed hypolimnion, while lakes of the third order show no stratification, due to their shallowness. The word “tropical” in the third column should not be taken too literally, seeing as how the majority of tropical lakes seldom if ever have a temperature of 4 °C in the epilimnion. In the oceans, where, in addition to temperature, salinity level determines the specific gravity of the water, epi‐ and hypolimnions1 can also appear under certain circumstances.

However, as matters here are not as clear as with red algae, we will satisfy ourselves with just this short annotation. Buder (33) pointed out a different phenomenon which could possibly also be understood as passive complementary adaptation. Purple bacteria, which are also photosynthetic, are often found under a layer of green algae or duckweed. These organisms must therefore be able to utilize the light that is let through by the green cells above them. The absorption band widths of the chlorophyll and of the pigmentation of the purple bacteria are more or less complementary.

This is especially visible with concentrated brines, which, in this case, can be compared to heat sources [in how the salt influences gas solubility] (see Chapter X, Brine). Gas volumes under pressure of 1 atmosphere at 0 °C, soluble in a given volume of water. (Bunsen & Carius) Temp. 0 Especially in the field of environmental sciences, one needs to realize that solubility, in terms of liquids in equilibrium with gases, as determined by physicists and chemists, is only a point of departure. In nature, both over‐ and under‐saturation occur more often than not.
