Benthic fauna community structure changes induced by the invasive species Marenzelleria spp. in Odense Fjord

STUDY SITE AND METHODS: Seden Strand is a shallow (<1.5m) brackish (10-15psu) estuary in the inner part of Odense Fjord. The sediment is mainly made of sand and in the southern part sand-silt. Since 1998, one sample was sampled at each site between May and August each year. Organisms retained on a 1mm sieve were identified and counted. Results presented here were processed with Primer 6.
