| All over the world hypersaline lake/lagoons are threatened by climate change. The marine Bakalskoye Lake (Ukraine) was studied in 2000-2012. The paper considers changing crustaceans within the context of the lagoon changes. A sharp drop of salinity occurred in 2004 due to a changed wind rose because the strong winds of Western direction began to dominate, and as a result, washing away of the spit began to be more intensive; and marine water inflow into the lake increased. The structure of primary productivity has changed completely; the total primary production decreased. A list of crustacean species found in the lake includes 19 species. In 2004 there was a change of the composition of crustaceans due to three factors - a change of salinity, an increase... |

| The shoreline zone is an area where the sea and land contact and plays a very important role in integrating a sea and its watershed in a whole system. Among the main environmental problems of the coastal zones, two critical ones are - coastal erosion and a biodiversity loss. Problems are most pronounced in semi-enclosed seas as the Black sea. Using results of the long-term studies in different parts of the Black Sea shoreline this paper attempts to make some steps to deepen our understanding of interactions between biodiversity loss and shoreline erosion. An analysis of the results from several case studies was done. Some mechanisms of interrelations between coastal erosion and biodiversity changes are also discussed. The increased concentration of mineral... |

| Arctodiaptomus salinus is a widespread species in different regions including Mediterranean. Long-term study has shown the presence of the species in the Crimean lakes under the salinity from 5 to 210 ‰. The logarithm of the species density in a lake is inversely proportional to salinity. Earlier experimental studies have shown that the upper salinity limit of the species is 70-100 ‰. Authors explain this discrepancy of field and experimental data that at salinities above 70-100 ‰ copepods consume exoosmolytes, mainly with food. A. salinus is an osmokonformer; to survive under osmotic stress it utilizes mechanisms of the cellular level – accumulates the osmolytes. Every time when we found A. salinus under high salinities, we observed unicellular green... |

| More than 70% of the beaches in the World are in decreasing stage during the past few decades, and the Black sea beaches are not exclusion. The paper gives a brief conceptual review of published and unpublished results of author’s long-term complicated study (1995-2010) in different areas of the Crimean coastline. Interconnections between marine communities and beach erosion are analyzed as well as some anthropogenic impacts on processes in beach area. Self-accelerating mechanism of beach erosion and marine communities degradation was suggested. Two interrelated components in the system “beach-sea” are crucial in regulating the balance of sand on the beach in our case - the coastal vegetation and benthic communities producing clamshells. Two stable state... |
