Information

Ecological parameter: geochemical imprinting

Parameter group: habitat related parameters

Explanation:
Describes the focus of distribution of a species with respect to its geochemical character. The focus of distribution is indicated in the pH spectrum.

Abbreviations:
Category name: Abbreviations: Explanation:
acidobiont ACB occurrence at pH< 7, optimum at pH < 5.5
acidiphil ACF occurrence at pH around 7, predominant distribution at pH < 7
circumneutral CN occurrence in the range around pH 7
alkaliphil ALF occurrence around pH 7, predominant distribution at pH > 7
alkalibiont ALB occurrence exclusively pH > 7, optimum at pH 8.5
indifferent IND distribution in the pH spectrum without recognizable optimum
