Copepods come in first: rapid colonization of new temporary ponds
The sequence in which new colonists reach an empty habitat can be crucial for future development and species structure of communities. It is therefore important to assess species composition and abundance in the initial stages of habitat existence. In the present study we focussed on colonization of...

The sequence in which new colonists reach an empty habitat can be crucial for future development and species structure of communities. It is therefore important to assess species composition and abundance in the initial stages of habitat existence.

To confirm that no egg-bank was present, we conducted hatching experiments using sediment cores from six new ponds and two reference sites.
