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... |
