Quelques aspects du peuplement thécamoebien des sols de la province de Québec (Canada)

Abstract

A census of Thecamoebae in 295 soil samples, mostly from the Province of Quebec (Canada), has yielded a total of 143 species and varieties. As a whole, these Thecamoebae populations differ little from those found in comparable biotopes throughout the world. A new family, Distomatopyxidae, and a new genus, Puytoracia (Euglyphidae), have been studied.Biogeographic, biocenotic, and ecological aspects are discussed. Mathematical analysis (factor analysis of affinities) has led to the definition of 16 associations of species for the various biotopes.
