Hyalospheniformes
Hyalospheniidae is a group of testate amoebae and the sole family of the infraorder Hyalospheniformes. Hyalospheniid testate amoebae are considered important bioindicators, which is why they are frequently used for environmental monitoring and their fossils are studied to investigate the paleoecology. Phylogeny The following cladogram illustrates the evolutionary relationships between all hyalospheniid genera found through phylogenetic analysis, with the exception of '' Porosia'', a genus excluded from the analysis that appears to be closely related to '' Certesella'' and is therefore placed next to it in the cladogram. Classificaton The current taxonomy of the family recognizes 14 genera: * Infraorder Hyalospheniformes Lahr et al. 2019 ** Family Hyalospheniidae Schulze 1877 emend. Kosakyan & Lara 2014 *** ''Alabasta'' Duckert et al., 2018 *** '' Alocodera'' Jung, 1942 *** ''Apodera'' Loeblich & Tappan, 1961 *** '' Certesella'' Loeblich & Tappan, 1961 *** '' Cornutheca'' Kosakyan e ...

Hyalosphenia Papilio
Arcellinid testate amoebae or Arcellinida,http://www.microscopy-uk.org.uk/mag/artjun03/gsamoebae.html Testate amoebae, peat bogs and past climates. accessed 16 march 2007 Arcellacean or lobose testate amoebae are single-celled protists partially enclosed in a simple test (shell). Arcellinid testate amoebae are commonly found in soils, leaf litter, peat bogs and near/in fresh water. They use their pseudopodia, a temporary cell extension, for moving and taking in food. Like most amoebae, they are generally believed to reproduce asexually via binary fission. However a recent review suggests that sexual recombination may be the rule rather than the exception in amoeboid protists in general, including the Arcellinid testate amoebae. Test or shell Simple tests are made by secretion (autogenous tests), agglutination of foreign material (xenogenous tests), or sometimes a combination of both. Past environmental changes can be determined by analysing the composition of fossil tests, includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
