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 |
An Oslofjord benthic community showed a range of variability for its constituent populations from small to large fluctuations over a two-year period. The five common species completing at least one turnover of all individuals within the time span studied showed stable equilibria, being persistent within bounds of ±10% of the transformed mean. Althougb rare species were highly variable in abundance and the dominance patterns of common species changed over time, overall, the community showed a consistent pattern of tbe distribution of individuals among species. Adjustment occurred within the cominunity so that increases in the abundance of some species were accompanied by decreases in the abundance of others to maintain the overall pattern. It is suggested that this consistency of pattern describes a community at dynamical equilibrium where species are able to fluctuate in abundance but, by means of adjustment of densities, a stable pattern holds. |
