Information
Ecological parameter: living form
Parameter group: life related parameters
Explanation:
The parameter provides information on shape, size, level of organisation, colony, filament or bristle formation and for some taxa, feeding mode and systematics. Modified after "Harmonised Taxalist Germany (HTL) - Phytoplankton" (Mischke et al., 2020).
