Feeding biology of a predatory and a facultatively predatory nematode (<i>Enoploides longispiculosus</i> and <i>Adoncholaimus fuscus</i>) OMA
Moens, T.; Verbeeck, L.; Vincx, M..
This paper reports on the feeding biology of a predatory and of a facultatively predatory nematode, <i>Enoploides longispiculosus</i> and <i>Adoncholaimus fuscus</i>, respectively. Both species represent genera which are common and abundant in the littoral of the North Sea and in adjacent estuaries. Observations on the foraging behaviour of both species are given, and for the former species, a range of prey from its natural habitat is identified. Respiration was determined using a polarographic oxygen electrode technique and compared to consumption determined as predation rates on the monhysterid nematode <i>Diplolaimelloides meyli</i>. The daily C-loss due to respiration accounted for 15% of the measured C-consumption...

Selective attraction of marine bacterivorous nematodes to their bacterial food OMA
Moens, T.; Verbeeck, L.; de Mayer, A.; Swings, J.; Vincx, M..
This paper explores the role of selective attraction to food in determining the spatial (micro)distribution of closely related nematode species. The attractiveness of 3 different bacterial strains to 4 species of Monhysteridae, <i>Diplolaimelloides meyli, Diplolaimella dievengatensis, Monhystera</i> sp. and <i>Geomonhystera disjuncta</i>, was studied in a multiple choice design. In our study area, the 4 nematode species considered are associated with <i>Spartina anglica</i> detritus decay and have partially overlapping microhabitat preferences. As they all belong to the same feeding guild, they are potential competitors for food. Each of the 4 nematode species was attracted to the bacterial strain B1, but important...
