Studies were carried out in subalpine meadows in the “Massif Néouvielle” in Central Pyrenees (France). Three habitats differing in humidity, temperature and soil pH were selected:1–dry and warm acidic soil, 2–medium dry, acidic soil, 3–wet and cold, neutral soil. One hun-dred and forty nematode species belonging to 7 orders, 21 families and 71 genera were found instudied material. Quantitative parameters: total number, numbers of families and genera of nematode communities from analyzed sites were poorly differentiated. However, great differences were found in composition and structure of studied communities. Dry and warm soil was domi-nated by nematodes of three orders: Areolaimida (27.02%), Dorylaimida (25.48%) and Tylenchida (24.32%), eudominants being genera: Aporcelaimellus, Paratylenchus and Prismatolaimus. Inmedium dry soil dominated Tylenchida (44.54%), Areolaimida (17.38%), Rhabditida (14.5%) and eudominants were: Acrobeloides, Rhabdolaimusand Rotylenchus. Enoplida (63.01%) dominated in wet and cold soil and eudominant was Rhabdolaimus. Shannon Index of diversity for genera in dry and warm soil was 3.77, in medium dry 4.24, and in wet and cold soil 3.06. Fourteen species were common for all three sites. Low values of Sørensen’s similarity index (below 40%) show alow similarity at aspecies level between communities from various sites.
