FIGURES 47–56 in Taxonomic and ecological characterization of two Ulnaria species (Bacillariophyta) from streams in Cyprus
FIGURES 47–56. SEM outside (Figs. 47, 49–54) and inside views (Figs. 48, 55–56) of Ulnaria acuscypriacus sp. nov. Figs. 47–48. Complete thecas: note the central area. Figs. 49–51. Details of the endings: Note the rimoportula and the biseriate striae. Figs. 52–53. Details of the apices of frustules in oblique position: Note the apical pore fields (number and arrangement of porelli) and the copulae with a single row of poroids at the advalvar side. Fig. 54. Central part of the valve: Note the central area, some ghost striae, and the striae closest to the central area becoming biseriate towards the valve margin. Fig. 55. Central part of the valve. Fig. 56. Apex: Rimoportula and ocellolimbus. Scale bars: Fig. 47 = 50 μm; Fig. 48 = 40 μm; Figs. 49, 52, 54–56 = 3 μm; Figs. 50–51 = 2 μm; Fig. 53 = 4 μm.
FIGURES 20–27 in Taxonomic and ecological characterization of two Ulnaria species (Bacillariophyta) from streams in Cyprus
FIGURES 20–27. LM views of two taxa with which Ulnaria monodii comb. nov. can be compared. Figs. 20–23. Morphodeme with narrower, almost rostrate ends occurring in the assemblage used as main reference for this study (cLIM004 DIAT 2136). Figs. 24–27. Ulnaria ungeriana, that appears sporadically together with U. monodii comb. nov., but note the prominent central area and usually shorter cells. Scale bar, 10 μm (all 1500x).
FIGURES 37–46 in Taxonomic and ecological characterization of two Ulnaria species (Bacillariophyta) from streams in Cyprus
FIGURES 37–46. LM views of Ulnaria acuscypriacus sp. nov. Figs. 37–41. Whole valves. Scale bar, 10 μm. Figs. 42–46. Variability of the apices in the populations sampled in Cyprus. Scale bars, 10 μm. Note the central area, and the apical rimoportula.
FIGURES 2–19 in Taxonomic and ecological characterization of two Ulnaria species (Bacillariophyta) from streams in Cyprus
FIGURES 2–19. LM views of Ulnaria monodii comb. nov. Figs. 2–4. Whole valves. White scale bars, 10 μm (750x). Note the complete absence of a central area. Figs. 5–7. Variability of the apices in the population used as main reference for this study (cLIM004 DIAT 2136). Figs. 8–16. Variability of the apices in the populations sampled in Cyprus. Note the apical rimoportula. Figs 17–19. Girdle views. Note the apical spines, the rows of rather large poroids on the copulae, and short-chain formation in Fig. 19. Black scale bar, 10 μm (1500x).
FIGURES 32–36 in Taxonomic and ecological characterization of two Ulnaria species (Bacillariophyta) from streams in Cyprus
FIGURES 32–36. SEM inside views of Ulnaria monodii comb. nov. (Figs. 32–34) + SEM outside views of morphodeme with narrower, almost rostrate ends (Figs. 35–36). Fig. 32. Complete theca: Note complete absence of signs of central area. Fig. 33. Details of the ending: note the prominent rimoportula. Fig. 34. Central part with details of the alveoli, areolae: Note the virgae-vimines structure. Fig. 35. Details of the ending: Note the apical rimoportula and spines, and the ocellolimbus (number and arrangement of porelli). Fig. 36: Details of the apex of an entire frustule: Note girdle bands with a row of rather large poroids. Scale bars: Fig. 32 = 60 μm; Fig. 33 = 4 μm; Fig. 34 = 5 μm; Figs. 35–36 = 3 μm.
FIGURES 1–13 in Ulnaria verhaegeniana, a new diatom (Bacillariophyta) species from Belgium
FIGURES 1–13. Ulnaria verhaegeniana sp. nov. Type population from the river Zenne, Sint-Pieters-Leeuw (sample VMM156-2016). Figs 1–13. LM views of entire valves. Scale bar = 10 μm.
FIG. 4 in Morphological description and molecular phylogeny of two diatom clones from the genus Ulnaria (Kützing) Compère isolated from an ultraoligotrophic lake at the Pole of Cold in the Northern Hemisphere, Republic of Sakha (Yakutia), Russia
FIG. 4. — Phylogenetic analysis of rbcL gene fragments, carried out by the maximum likelihood method. In the tree nodes there are bootstrap values obtained for n = 1000 replicas. Evolution distances are determined by the GTR method with Gamma distributed equal to four. ● Marked sequences obtained in this work.
