Ecological parameter: microhabitat - vertical distribution

Parameter group: habitat related parameters

Explanation:
The parameter indicates whether the habitat of a species -– regardless of the actual choriotope - –is more associated with the interstitial zone (space between the subtrate particles) or the substrate surface.

Type of assignment: single category assignment system ()
