The paper presents the first data of an unreported plant community dominated by Hordeum leporinum Link and Bituminaria bituminosa (L.) Stirt. (class Stellarietea mediae R. Tx., Lohmeyer et Preising in R.Tx. 1950). It is currently established in four localities in the region of the Black Sea coast, between the town of Ravda and the town of Nessebar, Bulgaria. Among the characteristic features of the community are: (i) it occupies places with an active human presence near the beach; (ii) preferences for shallow san-dy or rocky soils; (iii) Bituminaria bituminosa (L.) Stirt. as a dominant, diagnostic and constant species for the community. Other diagnostic species for the association are Anchusa officinalis L., Malva sylves-tris L., Sonchus arvensis L. and Avena fatua L. (iv) annual and perennial species have an equal participa-tion in the community; (v) increased presence of diagnostic species for the class Artemisietea vulgaris Lohmeyer et al. ex von Rochow 1951. Phytogeographically, the species composition of the community has a strong Mediterranean influence. In close proximity to its reléves there are always communities of xerophytic shrubs or low trees (in many cases alien species, such as Amorpha fruticosa L., Ziziphus jujuba Mill. and Robinia pseudoacacia L.) that participate in the association without forming a full second layer (their cover abundance is less than 30%).

One adult specimen of small red scorpionfish Scorpaena notata Rafinesque, 1810 was found in the ichthyological collections of the National Museum of Natural History in Sofia, Bulgaria. The specimen has been caught on 12 May 1926 in Black Sea near the town of Burgas and labelled as Scorpaena porcus. This is the first finding of the species along the Bulgarian Black Sea coast and the oldest record in the Black Sea.

Abrasion coasts (cliffs) are characterized by heterogeneity of the spatial structure and mobility of the substrate, which creates specific environmental conditions for plants. Nevertheless, plant communities of cliffs of the Black Sea coast of the Northwestern Caucasus are well developed due to the presence of a large number of Mediterranean species that are well adapted to such conditions. Communities are also supplemented by local endemics and representatives of petrophytic vegetation of adjacent areas. As a result, a specific plant community is formed on the cliff, represented by species from different floristic areas. Thus, the aim of this work was to analyze the species composition of higher vascular plants of the abrasion shore area of the Black Sea coast of the Northwestern Caucasus. On the studied cliff, 131 species of vascular plants were found, including 5 Crimean-Novorossiysk and 6 Novorossiysk endemic, as well as 6 species found in the Red List of the Russian Federation. Extreme unevenness in the density distribution of vegetation was noted, which may be due to the heterogeneity of the relief and the mobility of the substrate. Analysis of supraspecific taxa (families) showed the predominance of representatives of the Apiaceae, Fabaceae, and Poaceae families in the plant community. In addition, chorological analysis of vascular plant species was performed. The data of the performed chorological analysis confirm the relation of the studied territory to the Crimean Novorossiysk province. Thus, despite the specific environmental conditions, the plant community of the studied cliff is rich in species, including endemic species.

Status of the Gannet Morus bassanus in the Black Sea region (E Bulgaria) The Gannet Morus bassanus is a rare vagrant species in the Black Sea region (E Bulgaria). There are altogether 9 records of Gannet in Bulgaria over the last 100 years, all on the Black Sea coast. This paper describes the three most recent records. On 29-31 July 2008 6 individuals were observed in the vicinity of St. Constantine and Elena Resort (12 km north of the town of Varna, Varna Region, NE Bulgaria). Gannets were fishing by numerous (typical) dives, accompanied by a flock of Cormorants Phalacrocorax carbo and Yellow-legged Gulls Larus michahellis. A review of all the species' records in Bulgaria, as well as the subfossil records in the Black Sea region is given.

Typical coastal elements of limans and lagoons are barriers, that separate limanic aquatories from a Seas. On limanic shores structure of the Black Sea sand barriers represented three longitudinal landscape “zones”: sea beach (“frontal”), dune-aeolian and limanic (“back of the barrier”). They closely interactive between themselves under influence of lithodynamical exchanges of sediment. General tendency of the barriers dynamics is displacement to Land direction.

A new species of the genus Cimmerites Jeannel, 1928, C. maximovitchi sp. nov., is described from the Akhunskaya Cave and Labirintovaya Cave, both located in the Akhun Karst Massif on the Black Sea Coast of the West Caucasus (Krasnodar Territory, Russia). The new species is rather isolated within the genus Cimmerites and occupies an intermediate position between species related to C. kryzhanovskii Belousov, 1998 and species close to C. vagabundus Belousov, 1998. Though both C. maximovitchi sp. nov. and C. kryzhanovskii are still known only from caves, these species are quite similar in their life form to other members of the genus which are all true endogean species.

The Black Sea, surrounded by six riparian countries, is under the threat of severe pollution, giving rise to the need of taking precautions to protect it from further deterioration. In this paper, an effort putting forth a wastewater treatment and management strategy is outlined for the Black Sea coast of Turkey, including both the technical and financial aspects. The present situation of the coast in terms of land-based pollution and infrastructure is stated, followed by an applicable management strategy. The strategy developed for the coastal settlements involves various stagewise treatment schemes based on population distribution and densities along the coastline, and on the availability of land in a specified period of thirty years. Similar strategies are proposed for the control of pollution originating from industries, for those carried by rivers joining the sea, and for leachate of solid waste landfills. The cost estimations of various treatment schemes are also given in terms of population equivalents.
