Over het archief
Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.
Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

| Abstract |
Biological and chemical-physical data were obtained from burrows of the red swamp crawfish, Procambarus clarki, and the adjacent ponds and ditches during the burrowing period. Burrows constructed by mature and immature crawfish were of the same general pattern. Burrows usually consisted of an undulating downward channel, varying in depth, devoid of a connection with the adjacent pond or ditch. The tunnel was covered by a chimney or mud plug at the top and was enlarged at its deepest part into a chamber. Variance in the diameter of the channel seemed correlated with the total body-length of the inhabiting crawfish. Fauna present in burrow water consisted mainly of planktonic crustaceans. In general, the animal groups in burrows were similar to those present in the adjacent pond or ditch but fewer species and numbers occurred in the burrows. The benthic fauna in the burrows were dominated by Oligochaetes whereas aquatic insect larvae, mainly Diptera dominated in the ponds and ditch. |
