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 hundred and forty nematode species belonging to 7 orders, 21 families and 71 genera were found in studied 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 dominated by nematodes of three orders: Areolaimida (27.02%), Dorylaimida (25.48%) and Tylenchida (24.32%), eudominants being genera: Aporcelaimellus, Paratylenchus and Prismatolaimus. In medium dry soil dominated Tylenchida (44.54%), Areolaimida (17.38%), Rhabditida (14.5%) and eudominants were: Acrobeloides, Rhabdolaimus and 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 a low similarity at a species level between communities from various sites.
