A comparison of the abundance and diversity of fossil pigments in wetland and woodland humus layers.

Abstract

Describes a study in Minnesota showing that the preservation of photosynthetic pigments or their derivatives deposited in woodland humus layers and bog or swamp peats depends greatly on the degree of soil waterlogging on approximately neutral to moderately acid sites. Highly acid Sphagnum bogs do not favour preservation to the same degree, although pigment diversity is about equal in Thuja occidentalis/Larix laricina swamps and Picea mariana/Sphagnum bogs. Analysis of fossil pigments can provide evidence of swamp or bog intervals in the evolution of aquatic ecosystems.
