Abstract We report the occurrence of the European otter (Lutra lutra Linnaeus, 1758) along the entire Romanian Black Sea coast, for the first time. Several sightings were within the harbor and the city of Constanţa, indicating that the otter can accommodate to and tolerate high human impact. The report is based on observations made between 2012 and 2015. The species has been previously reported from all Romanian regions but not from the Black Sea coast. The occurrences reported within this article confirm an extension of the range of this Near Threatened species on the Romanian Black Sea coast, most probably due to the increasing of population size from other sources such as the Danube floodplain.

Data of genetic analysis of the Black Sea trematodes of Cainocreadium genus and Helicometra fasciata were obtained for the first time. The nucleotide sequences of ITS1 rRNA gene cluster of Cainocreadium flesi from Platichthys flesus (GenBank entries MG980645, MG980646) and Cainocreadium sp. from Gaidropsarus mediterraneus (MG980643, MG980644, MK248037, MK248038) off Crimean Black Sea coast were found to be identical. Nevertheless, they have not been synonymized because of morphological differences known between these hostal morphs. Sequences of Cainocreadium from the Black Sea fish turned out to differ, by 4 positions, from similar sequences of a closely related Mediterranean congener, C. labracis (cercaria). Five insertions-deletions and 38 nucleotide sequences distinguish the ITS1 sequences of the Black Sea trematodes, C. flesi and Cainocreadium sp., from ITS1 sequences of another Mediterranean congener, C. dentecis. The ITS1 sequences of the Black Sea and Mediterranean Helicometra fasciata samples also differ: 5 nucleotide changes and 11 insertions-deletions were identified.

Abstract The studies on the marine and freshwater testate amoebae of the Bulgarian Black Sea littoral and some related coastal brackish lakes are briefly reviewed. So far, a total of 184 species and subspecies of testate amoebae from 18 families and 45 genera from orders of Arcellinida and Euglyphida were published in national and international journals. The underground waters of the Bulgarian marine sand supralittoral are better studied than the related continental lakes. A total of about 45 species of marine interstitial testate amoebae are known, so far, and a big part of them were for the first time described from the Black Sea littoral. It’s interesting to note the presence in the marine underground waters of the Black Sea littoral of many freshwater testate amoebae also, considered by us as eurybionts. That is due of the low and variable salinity of the littoral Black Sea waters during the year. The presence of some psammobiotic testate amoebae as Psammonobiotus lineare and Corythionella georgiana in some related brackish lakes is also of ecological interest. The general conclusion of the present synthesis is that the testate amoebae fauna of the Bulgarian Black Sea coast and the related with it many brackish and freshwater littoral lakes is few known yet and need more active researches.

AbstractA multitude of recent studies have detailed microplastic concentrations in aquatic and terrestrial environments, although questions remain over their ultimate fate. At present, few studies have detailed microplastic characteristics and abundance along a freshwater–marine interface, and considerable uncertainties remain over the modelled contribution of terrestrial and riverine microplastic to the world’s oceans. In this article, for the first time, we detail sedimentary microplastic concentrations along a River–Sea transect from the lower reaches of a major continental river, the River Danube, through the Danube Delta, the Black Sea coast to the Romanian and Bulgarian inner shelf of the Black Sea. Our results indicate that isolated areas of the Danube Delta are still relatively pristine, with few microplastic particles in some of the sediments sampled.

An Oriental species of whiteflies, Aleuroclava aucubae (Kuwana, 1911), was collected for the first time from the territory of Russia (the Black Sea Coast of Russian Caucasus, Sochi National Park). The species was found to form dense colonies of ultimolarvae (pseudopupae) on leaves of Ficus carica and Ulmus glabra. Some of the ultimolarvae were infected by the fungus Conoideocrella luteorostrata (Zimmermann, 1901) Johnson et al., 2009. A morphological description of the pseudopupa of A. aucubae, with the original figure and photos are provided.

The article presents the diversity of the Black Sea coast of the Krasnodar Territory interethnic composition, in Novorossiysk particular. The ethnic composition of the city is represented, and the "dialogue of cultures" is the most favorable ground for the development of peace and harmony in the region, where the communication of modern cultures with each other enriches each of the cultures, as well as the interaction of traditions and innovations in all its directions.

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.
