Substrate preference : in sandy lowland streams 1 an experimental approach

Research output: Contribution to conferencePosterProfessional

Abstract

Hydromorphological conditions in lowland streams will change due to an increase of discharge peaks. Substrate stability, which is a key parameter at habitat scale for macroinvertebrates, will decrease. This poster shows laboratory experiments that were used to examine substrate preferences of three species of Trichoptera that represent stream specialists (Halesus radiatus, Micropterna sequax and Chaetopteryx villosa), and three stream ubiquists (Anabolia nervosa, Limnephilus lunatus and Mystacides longicornis). Knowledge on preferences is needed as reference to evaluate hydromorphologic disturbance
