Nematode populations of seven soils with grazed pasture were sampled monthly for 12-36 months and two of the soils received irrigation; a total of 46 nematode genera were identified from the 13 site-yeras. Diversity, evenness and simailarity of the faunae were assessed. Diversity was not related to pasture productivity and evenness was negatively correlated with the abundance (16-44%) of the domninant genus. Genra present were 21-35, but baried from 21 to 27 in one soil during 3 yr. In this group of soils under pasture Czekanowski's similarity coefficient showed repolicated sampling within a soil generally yielded nematode faunae more simailar to each other than to faunae in other soils, while analysis of variance showed genera to be more influenced by site than month. |
