Algae samples were collected during different seasons from 1997 to 2011 in two swamps located at Zvenigorod Biological Station in Moscow Region. There were found 25 Cosmarium species and varieties, 9 taxa of them being new to the region. Descriptions of the taxa were specified by observation of cell wall ornamentation with light and scanning electron microscopy. Original descriptions, photos and drawings of algae are presented.

Parsimony Analysis Of Endemicity

Rivers as barriers to dispersal and past forest refugia are two of the hypotheses proposed to explain the patterns of biodiversity in the Atlantic Forest. It has recently been shown that possible past refugia correspond to bioclimatically different regions, so we tested whether patterns of shared distribution of bird taxa in the Atlantic Forest are 1) limited by the Doce and São Francisco rivers or 2) associated with the bioclimatically different southern and northeastern regions. We catalogued lists of forest birds from 45 locations, 36 in the Atlantic forest and nine in Amazon, and used parsimony analysis of endemicity to identify groups of shared taxa. We also compared differences between these groups by permutational multivariate analysis of variance and identified the species that best supported the resulting groups. The results showed that the distribution of forest birds is divided into two main regions in the Atlantic Forest, the first with more southern localities and the second with northeastern localities. This distributional pattern is not delimited by riverbanks, but it may be associated with bioclimatic units, surrogated by altitude, that maintain current environmental differences between two main regions on Atlantic Forest and may be related to phylogenetic histories of taxa supporting the two groups.

Distal Seta

Recent surveys of the copepod fauna associated with the sponge Ircinia felix (Porifera, Dictyoceratida) in Brazil resulted in the discovery of a new siphonostomatoid species belonging to a recently erected genus of Asterocheridae. Setacheres portobarrensis sp. nov. possesses a 21-segmented antennule, with 3 free distal segments, after the aesthetasc. The third exopodal segment of leg 3 shows a distal seta instead of a spine as in some other congeners. The new species shows several unique features on the third endopodal segment of the antenna, the mandibular stylet, the inner lobe of the maxillule, and setules and spinules located in specific regions of legs 1 to 4. Setacheres portobarrensis sp. nov. follows the same distributional pattern as its congeners, and this is the first record of a siphonostomatoid copepod associated with Ircinia felix.

The Difference

In this paper we consider plant (geobotanical) indicators of soils, occurring in regressive bogs in the north taiga subzone of West Siberia. The specificity of regressive bogs is the difference between current vegetation and botanical composition of the peat surface horizon, which complicates their biological diagnostics. The data on peat botanical composition, degree of decomposition and thickness are presented. Destructive oligotrophic peat soils, the allocation of which is provided in the actual Russian soil classification at the level of subtype, occur in palsa bogs under shrub-lichen vegetation. Their indicators include lichens: Cladonia stellaris, C. rangiferina, C. stygia, C. arbuscula, C. mitis, Alectoria ochroleuca, Сetraria islandica, C. laevigata, Flavocetraria cucullata, F. nivalis, Govardia nigricans. A new subtype - peat oligotrophic regressive soils - which occurs in non-freezing bog is suggested. The indicators of this soil subtype in pine-shrub-sphagnum bogs are lichens Cladonia cenotea, C. chlorophaea, C. coniocraea, C. cornuta, C. crispata, C. deformis, C. gracilis, C. fimbriata, C. mitis, C. ochrochlora, C. pleurota, C. polydactyla, C. pyxidata, C. rangiferina, C. stellaris, C. subulata, C. sulphurina and liverwort Mylia anomala . The indicators of regressive soils in bog hollows are mainly liverwort Cladopodiella fluitans , mosses Warnstorfia fluitans , W. exannulata , and lichen Cetrariella delisei .
