Morphology, Biometry, Ecology and Biogeography of Five Species of Difflugia Leclerc, 1815 (Arcellinida: Difflugiidae), from Tiete River, Brazil

並列摘要


Difflugia corona Wallich, 1864; D. gramen Penard, 1902; D. lanceolata Penard, 1890; D. claviformis Penard, 1899 and D. gigantea Chardez, 1967 collected at the Tiete River Ecological Park (Brazil) are redescribed and compared to previous descriptions regarding morphology, biometry, ecology and geographical distributions. The biometrical measures and analysis based on a large number of individuals shows that natural populations of testate amoebae may be highly variable. Distinguishing traits for each species are discussed. The five Difflugia species inhabit quite a large range of micro habitats. The geographic distribution for each species is reviewed.
