Mitchell et Lara.Ĭopyright © 2012 Elsevier GmbH. For less abundant species like Nebela tincta we found an increase of biomass in all treatments, compared to control plots. The average abundance of Nebela collaris sensu lato was 29582 ind. mixotrophy, respectively) could explain such variability. 2003 Formats Abstract Population dynamics and food preferences of the testate amoeba species complex Nebela tincta major-bohemica-collaris (Nebela collaris sensu lato) were described from a Sphagnum peatland over one growing season. The variability of their functional traits (heterotrophy vs. However, it is difficult to compare all these. was sensitive to pollution by Cu in activated sludge and in sediments. was sensitive to industrial pollution and Nebela tincta was sensitive to NO 2. Plate-less specimens of Nebela tincta have also been found in my samples. was sensitive to urban pollution, Centropyxis sp. This species has earlier been called Hyalosphenia tincta. papilio differs markedly between them, irrespective to ecological settings. Nebela tincta occuring in Sphagnum, is often found without plates, its structu-reless test and lateral pits giving it a strong resemblance to a Hyalosphenia. Feeding Behavior of Testate Amoeba Specimens along the Ecological Gradient. homotypic synonym: Hyalosphenia tincta Leidy 1879. They produce a decay-resistant test, or shell, which can be identified to species in most cases and recovered from sediments in quantities sufficiently large to permit estimation of relative abundance. (2016), and to revive it now as the valid senior subjective synonym of. tincta were significantly less abundant in top segments than in bottom segments (fen area: an average of 160 50 and. Nebela tincta Taxonomy ID: 318538 (for references in articles please use NCBI:txid318538) current name. Testate amoebae are common inhabitants of moist soils, wetland, and lacustrine habitats. It is no longer found in its original meaning in major compendia such as Grospietsch (1958) and Tsyganov et al. rotunda (Penard 1890), describe three new species: N. Nebela tincta (Leidy, 1879) (Awerintzev, 1906) fell into disuse, being used as valid name for the last time by Sudzuki (1964). tincta-collaris group and some obscure, easily overlooked species such as N. collaris (Ehrenberg 1848) Kosakyan et Gomaa, change N. We redefine Nebela tincta (Leidy) Kosakyan et Lara and N. We therefore revise the taxonomy of the group. We show here that small variations in test morphology that have been often overlooked by traditional taxonomy correspond to distinct haplotypes. Time To Try A Slick New Text Editor Called Tincta Mac. Our goals were (1) to clarify the taxonomy and the phylogenetic relationships within this group, and (2) to evaluate if individual genotypes corresponded to specific morphotypes and the extent of phenotypic plasticity. How to Disable McAfee Anker Nebula Soundbar Review Chock Full of Features but Lacking Range. We examined the relationship between morphological and genetic diversity within this species complex by combined analyses of light microscopy imaging and Cytochrome Oxidase Subunit 1(COI) sequences obtained from the same individual amoeba cells. The taxonomic validity of characters used to define species within this group is debated and causes confusion in studies of biogeography, and applications in palaeoecology. Nebela tincta-collaris-bohemica (Arcellinida) is a species complex of small to medium-sized (ca.100 μm) testate amoebae common in peat bogs and forest soils. 1-10 Online.Species identification by means of morphology is often problematic in protists. The Revised Classification of Eukaryotes. Name Homonyms Nebela Leidy, 1874 Bibliographic ReferencesĪdl, S.
