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

An energy budget was constructed for the marine nematode Monhystera disjuncta. Respiration was measured with a modified Cartesian diver technique, in which the nematodes were kept in agar inside the diver 'head'. The relationship between respiration and body weight was: R=1.53 W0.75. Body growth was exponential during the juvenile phase, with a growth rate equal to 0.61 d-1. After maturation the growth rate fell to 0,17 d-1. Food uptake was measured in experiments with radiolabeled bacteria. In one series of experiments the accumulation of radiolabel in the nematodes was followed. In a second series the decrease in labeling was followed when pre-labeled nematodes fed on unlabeled bacteria. A model for label uptake permitted the calculation of assimilation efficiency and consumption rates. Consumption rates thus measured, correspond well to those calculated from the growth, reproduction and respiration rates. Assimilation efficiency was low, around 25%. Production efficiency (P/(P+R)) was high: 60% for the population at stable age distribution, and up to 75% for reproducing females. This seems to be a general feature in nematodes.
