Bangia Atropurpurea

Data about distribution of Bangia atropurpurea (Roth) C. Agardh indicate that this species was found on relatively small number of localities in freshwaters in Europe and world. In Red List of Algae, in some countries, this species is defined as a extinct (Ex) (Poland) or as endangered (En) (Slovakia). In this study, morphological and ecological characteristics of rare and endangered species B. atropurpurea that was found on three localities in Serbia: in Trgoviski Timok River (East Serbia), Gvozdacka Reka River (West Serbia) and Raska River (South-western Serbia). The Raska River is new find of the species B. atropurpurea.

Among the conservation measures related to the preservation of plant diversity, an important place belongs to the creation and preservation of rare and endangered species in the crop conditions. Thus, the species Silene hypanica Klokov is under threat of extinction. This relict and endemic species is listed in the Red book of Ukraine, the European Red list, and 6th Resolution of the Berne Convention. Prospects for the conservation of this species are related to the study of its viability and require the development of effective methods of reproduction, in particular in vitro crop. The article presents the results of studies of one of the breeding stages in vitro – rhizogenesis of S. hypanica esplants and its dependence on the concentrations of β-indolyl butyric acid in nutrient media (0,1; 0,5; 1,0; 1,5; 2,0 mg / l), followed by adaptation of regenerating plants to ex vitro conditions. The study showed that the active process of rhizogenesis occurred due to the addition of β-IMC to the nutrient medium at a concentration of 0.5 mg/l and contributed to the production of 86.4 % of rooted regenerating plants. Transplanting rooted plants into peat disks and then growing them in containers contributed to the successful adaptation of rooted plants.

The aim of the study was to make an inventory and describe the localities of interesting species inhabiting the segetal communities of the Turobin commune, which are regarded as endangered in Poland and Europe. The paper presents results of a field study conducted in 2011-2013 in crop fields, located on brown soils and rendzinas. Phytosociological relevés were made with the Braun-Blanquet method at the sites of phytocoenoses comprising interesting and endangered species. The habitat was assessed with the use of soil-agricultural maps, and soil pH was measured at the site where the phytosociological relevés were taken. In the Turobin commune, 32 interesting species were found; some of them are considered rare and endangered in Poland. In this group, the occurrence of Asperugo procumbens, regarded as an endangered species and included in the red list of vascular plants, is noteworthy.

The author offers mapping and geoecological analysis of the Russian Federation regions presence in the state program “Environmental Protection”. The unequal distribution of the program’s targets and activities in different regions is revealed. A considerable number of relevant environmental problems for several mentioned regions have not been reflected in the program. It is important to increase the area of specially protected natural areas for a significant number of subjects of the Russian Federation. The status “part of the territory occupied by specially protected natural territories of Federal value in the total area of the subject of the Russian Federation” is recommended to be assigned all regions of Russia. Identification and elimination of objects of accumulated environmental damage that threat to the Volga river is relevant, at least for all the regions in which the Volga flows. Not all regions with a high level of air pollution and/or large masses of air pollutants have the indicator “reduction of total emissions for the reporting year”. It is necessary to increase the Program of measures for the protection of rare and endangered species of plants and to expand the list of regions in which it is planned to protect rare and endangered species of animals.

Quantitative assessment and evaluation of ecological parameters and biodiversity conservation are prime concerns for long-term conservation of rare and endangered species and their associated habitats in any ecological region. In this study, Gansu Province, a biodiversity hotspot, was chosen as the research area. We predicted the distribution patterns of suitable habitats for rare and endangered species. The replacement cost method was adopted to calculate the conservation value of rare and endangered species. The suitable habitat distribution area of rare and endangered wild animals reached 351,607.76 km2 (without overlapping area), while that of plants reached 72,988.12 km2 (without overlapping area). The conservation value of rare and endangered wildlife is US $1670.00 million. The high-value areas are mostly concentrated in the south and north of Gansu Province. The conservation value of rare and endangered wild plants is US $56,920.00 million. The high-value areas are mostly concentrated south of Gansu Province. The conservation value is US $58,590.00 million a year, and its distribution trend is gradually decreasing from northeast to southwest, with the highest in the forest area south of Gansu Province, followed by the Qilian Mountain area in the north. These results are of great significance for future improvement of the evaluation index system of ecosystem services and the development of ecosystem services and management strategies.

[The spring presence of two individuals of the Sea lamprey, Petromyzon marinus, in the River Mignone near Tarquinia (Northern Lazio) could highlight a new Italian reproductive site of this rare and endangered species. This exceptional possibility could certainly be favored by the good quality of both the waters of the Mignone, and the environmental context of the record, but would require the urgent equipment of the barrier of Le Mole with a fish ladder in order to allow the sea lamprey’s upstream migration towards the areas of the upper course, even more suitable for their reproduction].   [Article in Italian]
