Ecological parameter: locomotion and substrate relation according to Tachet

Parameter group: life & body related parameters

Explanation:
The trait provides combined information on invertebrate locomotion and related substrate type. Organisms can be free-living or attached, temporarily or permanently. The category "flier" includes active fliers (e.g. aquatic adults of water bugs or beetles able to fly), but also passive fliers, i.e. aquatic organisms passively dispersed by birds (e.g. leeches, parasites of vertebrates) acting as carriers. Aquatic invertebrates can also be swimmers over (e.g. Gerridae) or under (e.g. Anophelinae) the water surface, swimmers in open water (e.g. Baetidae), crawlers over the bottom substrate (e.g. Blephariceridae, Ancylidae), burrowers within the first centimetres of the benthic fine sediment, or interstitial inhabitants (i.e. endobenthic), temporarily living in hyporheic habitats (e.g. Leuctra major).
