Some observations on harpacticoid populations, in relationship to the competitive exclusion principle OMA
Hauspie, R.; Polk, P..
In the field ecology of populations, two concepts are largely distributed and generally accepted:- the competitive exclusion principle states that organisms occupying similar ecological niches, come into competition and consequently cannot coexist. - the more two organisms are close to each other in phylogeny, the more they will tend to occupy similar niches. The results obtained from the study of populations of harpacticoids colonizing artificial substrata are somehow an illustration of these principles. Indeed, these species which coexist belong most of the time to different genera or even to different families.

Swimming behaviour patterns in certain benthic harpacticoids (Copepoda) OMA
Hauspie, R.; Polk, Ph..
During an investigation on the fouling of artificial substrata in a brackish-water biotope at Oostende (=Ostend), Belgium, it was found that some harpacticoid species, until now considered benthic, become pelagic at certain times. Also, we observed that these harpacticoids were swimming during certain periods and then were found in the plankton. Some observations about this phenomenon are discussed in this paper.
