Coexistence of ecotypes, genetically divergent population units, is a widespread phenomenon, potentially affecting ecosystem functioning and local food web stability. In coastal Skagerrak, Atlantic cod (Gadus morhua) occur as two such coexisting ecotypes. We applied combination acoustic telemetry, genotyping, stable isotope analysis to 72 individuals investigate movement ecology niche putative ...

The use of molecular techniques in insect ecology has expanded rapidly, allowing ever morechallengingquestions tobeaddressed.Comparedto their abovegroundequivalents, root herbivoremolecular ecology has received less attention, despite essentially the same ecological questions being of importance in both the aboveand belowground ecosystems. Studies so far have concentrated on economically import...
