Two new otoplanid species, from the interstitial habitats of the North-Western Mediterranenan sea coast, are described. The specimens show the typical morphological peculiarities of the subfamily Otoplaninae ("Turbellaria", Otoplanidae), but clearly differ from other species described in this group. Otoplana labronica sp. nov. is characterized by a body length of 1.2–1.5 mm, different features of the testes and vitellaries, the male sclerotic apparatus composed of a median aculeus (52–53 μm long) and 16 peculiar spines (19–44 μm long). This new species has the smallest number of spines (17) and the smaller body length, in comparison to all the species of the genus. Otoplana falcataspina sp. nov. is characterized by a body length of 2.3–2.4 mm, distinctive dimensions and arrangement of the vitellaries, the male sclerotic apparatus composed of a median aculeus (50–51 μm long) and 20–21 spines (22–44 μm long). This new species has a limited body length, and only the sexually mature specimens of the new species O. labronica exhibit a smaller size. They were collected below the low water mark on the sandy beaches at Calambrone and Marina di Vecchiano (Pisa, Ligurian Sea, Italy), respectively.

Paper summarizes information on the diversity of microscopic algae of 10 lakes of the north-western Black Sea coast (Bile, Kahul, Kartal, Katlabukh, Kytai, Pysarske, Sasyk, Safyany and Yalpug). A total of 339 species belonging to 135 genera, 62 families, 30 orders, 10 classes, 7 divisions were identified. The richest divisions were Bacillariophyta (198) and Chlorophyta (62) and Cyanophyta (40). Representatives of Euglenophyta (18), Charophyta (15), Ochrophyta (5) and Dinophyta (1) were less diverse. In the studied lakes, 13 new species were found for the Danube lakes and four species are first cited for the water bodies of the North-Western Black Sea Coast and the territory of Ukraine. Among them Pinnularia fonticola Hustedt is new record to Europe. Genera Nitzschia Hassall (26), Navicula Bory (15), Сymbella C.Agardh (9), Tryblionella W.Sm. (9), Desmodesmus (F.Chodat) An, Friedl et E.Hegew.(9), Caloneis Cleve (8), Gomphonema (C.Agardh) Ehrenb. (8), Euglena Ehrenb. (7), Cosmarium Corda et Ralfs (7) and Oscillatoria Vaucher ex Gomont (7) formed the basis of the species composition of algae in studied lakes. Morphologically, 189 species are unicellular, 119 colonial and 31 multicellular algae. Of these, 157 species are known as motile and 182 as immotile forms. On different types of substrates different numbers of microalgae species were identified. 148 species grew epiphytically on macrophytes; on solid substrates, 42 species were revealed on concrete and 38 on stones. On the bottom, 110 species were found on silt and 41 on sand. In relation to the level of water mineralization in the lakes freshwater species dominated (281). They include 221 species of indifferents, 58 halophiles and 2 halophobes. Mesohalobes were represented by 52 species, six species are marine (polyhalobes). Lakes Yalpug (198 species), Kugurluy (198) and Katlabukh (192) were the richest in microalgae species.

A New Species

A new species of Terebellidae, Pistacolinisp. n., has been identified from the harbour of Banyuls-sur-Mer, north-western Mediterranean Sea. This new species was found in very high densities, exclusively in gravelly sand deposited manually, and was not found in the original source habitat of the gravel. This species is characterized by the colour of the ventral shields with pinkish anterior part and a blood red posterior part in live specimens, a pair of unequal-sized plumose branchiae inserted on segment II and anterior thoracic neuropodia with long-handled uncini. The presence of long-handled uncini even in the smallest specimens constitutes the major difference between Pistacolinisp. n. and other Pista species with a single pair of branchiae such as P.lornensis and P.bansei.

Global warming is facilitating the poleward range expansion of plant and animal species. In the Mediterranean Sea, the concurrent temperature increase and abundance of (sub)tropical non-indigenous species (NIS) is leading to the so-called ‘tropicalization’ of the Mediterranean Sea, which is dramatically evident in the south-eastern sectors of the basin. At the same time, the colder north-western sectors of the basin have been said to undergo a process of ‘meridionalization’, that is the establishment of warm-water native species (WWN) previously restricted to the southern sectors. The Gulf of Genoa (Ligurian Sea) is the north-western reach for southern species of whatever origin in the Mediterranean. Recent (up to 2015) observations of NIS and WWN by diving have been collated to update previous similar inventories. In addition, the relative occurrences of both groups of southern species have been monitored by snorkelling between 2009 and 2015 in shallow rocky reefs at Genoa, and compared with the trend in air and sea surface temperatures. A total of 20 southern species (11 NIS and 9 WWN) was found. Two WWN (the zebra seabream Diplodus cervinus and the parrotfish Sparisoma cretense) and three NIS (the SW Atlantic sponge Paraleucilla magna, the Red Sea polychaete Branchiomma luctuosum, and the amphi-American and amphi-Atlantic crab Percnon gibbesi) are new records for the Ligurian Sea, whereas juveniles of the Indo-Pacific bluespotted cornetfish Fistularia commersonii have been found for the first time. While temperature has kept on increasing for the whole period, with 2014 and 2015 being the warmest years since at least 1950, the number of WWN increased linearly, that of NIS increased exponentially, contradicting the idea of meridionalization and supporting that of tropicalization even in the northern sectors of the Mediterranean basin.

A new species of the genus Speleophria is described from a cave in the Nullarbor region in southern Western Australia. Its congeners include species from the Balearics, Croatia, Bermuda, Yucatan peninsula and north-western Western Australia, all considered to be Tethyan relicts. However, the discovery of the new speleophriid in the Nullarbor region has important biogeographic and ecological implications. From the biogeographic perspective, it either suggests dispersal as the process determining the current distribution pattern of the aquatic fauna found on the Roe Plains or significantly extends the Tethyan track across Australia, from the north-western coastal margin of the continent to the southern coastal margin. From an ecologic perspective, the new speleophriid suggests the possible existence of anchialine habitats in southern Australia. Speleophria nullarborensis sp. nov. can be distinguished from its four congeners by its plesiomorphic 3-segmented endopod of the first swimming leg (2-segmented in other species) and unusually long innermost apical seta on the caudal ramus. Another character that easily distinguishes our new species, and seems to be an autapomorphic feature, is its constricted preanal somite.

The Baikal-Lensky State Natural Reserve was established in 1986. It covers a part of the north-western coastof Lake Baikal from Cape Onholoy to Cape Elokhin and the adjacent section of the Baikal ridge. The article describes thecharacteristics of the natural conditions of the reserve. Large-scale studies of the bryophyte flora in the reserve have not beencarried out. Currently, 195 species of bryophytes are known here (37 species of liverworts and 158 species of mosses). The listof bryophytes of the Baikal-Lensky Nature Reserve contains 33 species of liverworts and 135 leafy mosses. Platydictya acuminata (Lindb. et Arnel) Ignatov and Hamatocaulis vernicosus (Mitt.) Hedenäs are included in the Red Book of Irkutsk Oblast.Bryological material on the Baikal-Lensky nature reserve, collected by N. V. Stepantsova, has been analyzed. New species ofliverworts (4 species) and leafy mosses (19 species) were revealed. The territory of the Baikal-Lensky Nature Reserve requiresspecial bryological studies. Taking into account the peculiarities of the natural conditions of the reserve, we assume a significant replenishment of the list of bryoflora. We believe that the bryoflora of the Baikal-Lensky Reserve has been studied by lessthan 50 %. The detection of liverworts is approximately 25–30 %, leaf-stem mosses – 40–45 %.

Four ammonoid species are described from the Early Carboniferous (Mississippian) Iridet Formation of the Ahnet and Mouydir (Central Sahara, Algeria); three of which are new: <i>Eurites temertassetensis</i> n. sp., <i>Trimorphoceras teguentourense</i> n. sp., and <i>Trimorphoceras azzelmattiense</i> n. sp. The species can be attributed to the North African <i>Ammonellipsites-Merocanites</i> Assemblage (<i>Fascipericyclus-Ammonellipsites</i> Genus Zone; Late Tournaisian to Early Viséan). Additionally, the two new species <i>Ammonellipsites sguilmensis</i> n. sp. and <i>Muensteroceras beniabbesense</i> n. sp. are described from the time equivalent Hassi Sguilma Formation of the Saoura Valley (north-western Algeria). <br><br> doi:<a href="http://dx.doi.org/10.1002/mmng.200900012" target="_blank">10.1002/mmng.200900012</a>
