HETEROTROPHIC FLAGELLATES FROM FRESHWATER AND MARINE HABITATS OF SOUTH PATAGONIA AND TIERRA DEL FUEGO, CHILE

摘要

The species composition and morphology of free-living heterotrophic flagellates from freshwater, brackish, hypersaline and marine habitats of southern Chile were studied. Seventy-seven species and eight forms were found. The greatest number of species was observed in freshwater bodies: in a temporary spring shallow and well-warmed pond, Tierra del Fuego (31 species), and in a sphagnum bog, mainland Chile (29 species). A similarity analysis of the flagellate communities by species composition in different types of habitat showed the dependence of the formation of a community of heterotrophic flagellates on water mineralization. Micrographs and morphological descriptions for 25 species (Hyperamoeba flagellata, Bicosoeca cylindrica, B. exilis, B. lacustris, B. maris, B. vacillans, Paraphysomonas aff. bandaiensis, P. longispina, Anthophysa vegetans, Cercomonas gigantica, Paracercomonas metabolica, Metromonas grandis, M. simplex, Thaumatomastix triangulata, Thaumatomonas seravini, Spongomonas uvella, Histiona aroides, Reclinomonas americana, Percolomonas denhami, Heteronema globulifera, Petalomonas ornata, Distigma senni, Developayella elegans, Amastigomonas griebensis, Kathablepharis remigera) are given.
