文摘
- •
The whole Ebro Estuary, a salt wedge Mediterranean estuary, was exhaustively sampled.
- •
Ordination methods and GAMs identified two macroinvertebrate communities associated to fresh and saline conditions.
- •
The macroinvertebrate community of the Ebro Estuary experienced a total replacement distribution pattern from fresh to salt water.
- •
The ecological boundary of the Ebro Estuary fitted an ecotone model.
- •
The minimum species richness value was located in the surroundings of the null point, namely salt wedge tip.
