Information

Ecological parameter:  saprobity according to Tachet

Parameter group: sabrobic preference parameters

Explanation:
Following the saprobity system of water quality (Kolkwitz & Marsson 1909; Sládeček 1973), this trait describes the distribution of taxa along a gradient of organic matter availability/contamination from xenosaprobic (i.e. the lowest water saturation rate with decomposing organic substances in any water body; 1) to polysaprobic (i.e. the richest water bodies in decomposable organic matter; 5) systems. Indirectly, this trait provides information on the sensitivity of invertebrates to organic contamination. Five categories have been defined.
