Abstract The biodiversity of the entrance zones of the Montenegro caves is barely studied, therefore the purpose of this study was to assess the biodiversity of several caves in Montenegro. The samples of phototrophs were taken from various substrates of the entrance zone of 7 caves in July 2017. A total of 87 species of phototrophs were identified, including 64 species of algae and Cyanobacteria, and 21 species of Bryophyta. Comparison of biodiversity was carried out using Jacquard and Shorygin indices. The prevalence of cyanobacteria in the algal flora and the dominance of green algae were revealed. The composition of the phototrophic communities was influenced mainly by the morphology of the entrance zones, not by the spatial proximity of the studied caves. Key words: karst caves, entrance zone, ecotone, algae, cyanobacteria, bryophyte, Montenegro. Introduction The subterranean karst forms represent habitats that considered more climatically stable than the surface. -

IMARENABIO, La Serna 58, 24007 León, Spain Abstract: Thirteen Planothidium species are illustrated and discussed in a detailed morphological account based on light and scanning electron microscopy analysis of modern and historic materials related to the names Planothidium rostratum (Østrup) Lange–Bertalot and Planothidium frequentissimum (Lange–Bertalot) Lange– Bertalot. Eight species from freshwater environments in Europe, Asia and South America are proposed as new. All taxa here discussed and illustrated belong to the group of species characterized by the presence of a cavum in the rapheless valve. Additional information concerning their distribution and ecology is briefly commented based on a thorough literature revision.

Bacillariophyta) a Common Monoraphid Species from Southern Brazilian Rivers

(Bacillariophyta) a common monoraphid species from southern Brazilian rivers CARLOS E. WETZEL* & LUC ECTOR Public Research Centre - Gabriel Lippmann, Department of Environment and Agro-biotechnologies (EVA), 41 rue du Brill, L-4422 Belvaux, Luxembourg (E-mail: [email protected], [email protected] , corresponding author) Abstract A new species in the genus Planothidium is described, Planothidium bagualensis sp. nov., from rivers of the Rio Pardo hydrographical basin, Rio Grande do Sul, southern Brazil. This account is based on light and scanning electron microscopy. This rather common species was misidentified in previous studies conducted in Brazil as belonging to either a group of species related to Planothidium lanceolatum and its varieties, or Planothidium frequentissimum. The presence of a cavum (“hood”) in the rapheless valve, however, clearly separates it from P. lanceolatum sensu stricto which has only a sinus (“rimmed depression”); the wider and longer cells of P. bagualensis, besides having ultrastructural differences, sets it apart from P. frequentissimum. Planothidium bagualensis is widely reported in freshwater environments of southern Brazil. The species reached up to 45% of relative abundance in epilithic samples from eutrophic lotic environments of the Rio Pardo hydrographical basin. Traditional weighted-averaging approaches (WA) were applied to model phosphates (P), chemical oxygen demand (COD), total dissolved solids and pH optima. P. bagualensis is formally described and the literature reviewed to delimitate its distribution. -

A literature comparison was made with other similar species, including the LM and SEM analysis of original material bearing Achnanthes inflata (Kützing) Grunow housed at the Grunow Collection in Vienna, and data from the available literature. Samples were collected from clumps of moss growing on tree trunks, and from a concrete wall within the botanic garden. Four taxa from the genus Achnanthes were recorded: A.
