Open WL Archief (OWA)

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

Spatial structures of juvenile and adult cohorts of the gastropod Hydrobia ulvae were investigated over a surface area of several km² in an intertidal mudflat at the end of the recruitment period. Three cohorts (average shell lengths of 3.9 ± 0.89 mm, 1.8 ± 0.43 mm and 1.1 ± 0.18 mm for cohorts I, II and III, respectively) were identified by a statistical analysis and their spatial distributions were characterised. Cohorts of juveniles (cohorts II and III) showed a patchy distribution pattern, whereas the cohort of adults (cohort I) was homogeneously distributed over the study area. These marked differences in spatial distribution of cohorts are likely to have a strong effect on estimates of local demographic processes, and hence of population dynamics.
