Effects of resource diversity on active dispersal behaviour of 3 cryptic species of the nematode Litoditis marina

Our study investigated the effects of food diversity on effective dispersal of three sympatric cryptic species of the marine nematode complex Litoditis marina (Pm I, Pm III and Pm IV) using microcosms consisting of a local patch (i.e. inoculation plate), connection tube, and distant patch (i.e. dispersal plate). The patches had either identical or varying food-diversity treatments (Escherichia coli, low, medium, or high-diversity food).
