Resuming published and own data, a revision of classification of Chaetognatha is presented. The family Sagittidae Claus & Grobben, 1905 is given a rank of subclass, Sagittiones, characterised, in particular, by the presence of two pairs of sac-like gelatinous structures or two pairs of fins. Besides the order Aphragmophora Tokioka, 1965, it contains the new order Biphragmosagittiformes ord. nov., which is a unique group of Chaetognatha with an unusual combination of morphological characters: the transverse muscles present in both the trunk and the tail sections of the body; the seminal vesicles simple, without internal complex compartments; the presence of two pairs of lateral fins. The only family assigned to the new order, Biphragmosagittidae fam. nov., contains two genera. Diagnoses of the two new genera, Biphragmosagitta gen. nov. (type species B. tarasovi sp. nov. and B. angusticephala sp. nov.) and Biphragmofastigata gen. nov. (type species B. fastigata sp. nov.), detailed descriptions and pictures of the three new species are presented.

Abstract A Gram-stain-negative, gliding-motile, positive for catalase, facultative anaerobic, designated strain XSD401T, was isolated from the red algae of Xiaoshi Island, Shandong Province, China. Growth occurred at 20–37 °C (optimum, 33 °C), pH 5.5–9.5 (optimum, pH 6.5–7.5), and with 0.5–5% (w/v) NaCl (optimum, 3%). The main fatty acids are iso-C15:0, iso-C15:1 G, iso-C17:0 3-OH, iso-C15:0 3-OH, C16:0. Phosphatidylethanolamine (PE), three unidentified aminolipids (AL1, AL2, AL3) and one unidentified lipid (L) were the major polar lipids. The G+C content of the genomic DNA was 33.9 mol%. Strain XSD401T had the highest sequence similarity (96.88%) to the 16S rRNA gene of Psychroserpens damuponensis KCTC 23539T. The similarities with Psychroserpens burtonensis DSM 12212T was 96.31%. The dDDH values between strain XSD401T and P. damuponensis KCTC 23539T, P. burtonensis DSM 12212T, were 20.40% and 20.30%, respectively. The average nucleotide identity (ANI) values between strain XSD401T and P. damuponensis KCTC 23539T, P. burtonensis DSM 12212T were 76.91%, 76.88%, respectively. The differences in morphology, physiology and genotype from the previously described taxa support the classification of strain XSD401T as a representative of a novel species of the genus Psychroserpens, for which the name Psychroserpens luteus sp. nov. is proposed. The type strain is XSD401T (= MCCC 1H00396T = KCTC 72684T = JCM 33931T).

Abstract The fourth addendum to Schneider and Wynne’s 2007 “A synoptic review of the classification of red algal genera a half century after Kylin’s 1956 ‘Die Gattungen der Rhodophyceen’” is presented, covering the names of genus- and higher-level taxa added or modified since our third addendum (Bot. Mar. 59: 397–404). Since that synopsis, we added 21 new genera in a first addendum, 27 in the second, and 40 in the third, demonstrating the increasing amount of genetic work over more than a decade. In this fourth addendum, we add 58 new genera to the list of red algae as well as many new taxa in the hierarchical framework over the past 3 years. Based upon molecular sequencing, other genera reinstated from synonymy studies are included.

In the article an author formulates an aim: to describe and classify of communication technologies of the social engineering in the newspapers of Reichscommissariat "Ukraine" (RCU) in a period from September, 1, 1941 to July, 17, 1942. On results research: 1) it is set that more active than all in the newspapers of (RCU) on the first year his existence technologies of the first stage of the social engineering (namely are authentications) were used; 2) actively enough the authors of journalistic materials called to of communication technologies that declared "diffuse" character of confluence of two stages of the social engineering, namely are authentications and designs; 3) the no active enough (only in 9%) journalists of fascist newspapers of (RCU) called to of communication technologies of the stage of design of reality. Conclusions: the authors of journalistic materials did not aim to design future reality of "new order" of "Greatgermanium", and also did not have sufficient journalistic preparation and experience for realization Goebels and Hitler intentions.

We propose a new classification of periodic orbits of interval maps via over-rotation pairs. We prove a theorem for them similar to the Sharkovskii theorem.

Floristic classification of the cryopetrophytic alpine communities of the Altai-Sayan mountain system have been performed. The Rhodioletea quadrifidae Hilbig 2000 class of the Altai-Sayan mountain system includes two order, one alliance and six associations. We were described new order (Valerianetaliapetrophyllae order nova prov.) and three associations (Ranunculo akkemensis-Valerianetumpetrophilae ass. nova prov., Mesostemmo martjanovii-Leiosporetum exscapae ass. nova prov., Potentillo biflorae-Sibbaldietum tetrandrae ass. nova prov.) These associations include communities with a predominance of Asian alpine and arctalpine petrophytes.
