Abstract
A total of 243 samples from hemlock-hardwood, boreal forest and alpine tundra associations of New York, Vermont, New Hampshire and Maine [USA] were analyzed for species of Bakernema, Criconema and Criconemoides and for selected edaphic factors. The hemlock-hardwood formation contained 13 spp. of these genera, but the boreal forest and alpine tundra contained only Criconema menzeli and Criconemoides sphagni. C. axeste, C. rusticum and C. xenoplax were associated primarily with mineral soils that have high pH, low moisture after drainage, and organic matter content of less than 15%. C. sphagni was associated with organic soils that had low pH, high moisture after drainage and organic matter content greater than 15%. [The remaining species were B. inaequale, Criconema fimbriatum, C. octangulare, C. proclivis, C. seymouri, Criconemoides merassatus, C. longula and C. petasus].
