tincta did not have the same trophic position in the microbial food web, probably resulting from their different feeding strategies. the testate amoebae Hyalosphenia papilio and Nebela tincta along a narrow fen-bog gradient using digestive. Additionally, isotope analyses suggested that H. Gilbert D (2012) Characterizing the feeding habits of the testate amoebae Hyalosphenia papilio and Nebela tincta along a narrow. Nonmetric Multidimensional Scaling analysis clearly demonstrated that the two species did not have the same feeding habit along the “fen-bog” gradient, and furthermore that a significant spatial split exists in the feeding behavior of H. papilio, the most frequently ingested prey were ciliates (55%) and microalgae (35%). tincta were spores and mycelia of fungi (55%), microalgae (25%) and cyanobacteria (8.5%). However, this pattern might only reflect the past sampling bias towards. tincta 13 samples 75-164 x m L/W1.2-1.4 2003-2008: Nebela sp. Using DNA-barcoding for sorting out protist species complexes: a case study of the Nebela tincta-collaris-bohemica group (Amoebozoa Arcellinida. Among identified food sources, those most frequently ingested by N. The relative proportion of protist groups in these global estimates is mirrored by that of our list of Antarctic protists - ciliates (55 of the total of these groups globally vs 41 in Antarctica), Amoebozoa (31 vs 36), Cercozoa (9 vs 17) and Excavata (5 vs 6). 245 x 198 m L/W Komado marsh Showa & Tajima Fukushima, 2007 N. papilio was described from top segments, and that of N. Pseudostome ranging from linear to strongly curved, bordered by a thin organic lip (rim, collar or fringe). Diagnosis: Test rounded, ovoid-pyriform, or wide-pyriform, rarely with a keel (partial or complete) or other lateral expansions, with or without wavy lateral margins. Owing to their vertical distribution, the feeding habit of H. Genus Nebela (Leidy, 1874) sensu Kosakyan et al., 2016. amoebae (Protists) in Sphagnum in North-western Poland in. Observations of digestive vacuole content and stable isotope analyses (¹☼ and ¹⁵N) were used to establish the feeding behavior of both testate amoeba species. Characterizing the Feeding Habits of the Testate Amoebae Hyalosphenia Papilio and Nebela Tincta Along a Narrow Fen-Bog Gradient. within the Nebela tincta-bohemica-collaris group have been re-classified Kosakyan et al. Samples were collected in living “top segments” (0-3cm) and early declining “bottom segments” (3-6cm) of Sphagnum fallax peat. Structure of the Tree of Life page.Population dynamics and feeding habits of the testate amoebae Nebela tincta and Hyalosphenia papilio were studied along a short “fen” to “bog” gradient in a Sphagnum-dominated mire (Jura, France). The Tree of Life is that each branch can be further subdivided intoĭescendent branches, that is, subgroups representing distinct geneticįor a more detailed explanation of the different ToL page types, have a look at the Major distinction between a branch and a leaf of The numbers along the branches represent respectively the bootstraps obtained by maximum likelihood method and the posterior probabilities as calculated with Bayesian analyses. and related taxa testate amoebae COI sequences based on 677 nucleotide positions.

Données écologiques sur quelques Hyalospheniidae et Paraquadrulidae (Thécamoebiens) des sols (Deuxième partie: genre Nebela). the Testate Amoebae Hyalosphenia papilio and Nebela tincta along a Narrow Fen-Bog Gradient. The reversible nature of variability in protists was demonstrated by Heal (1963), who induced an increase in shell size in the testate amoeba Nebela tincta.
