Potential Impact

Extensive grazing by gastropods was found on endangered Boreal Felt Lichen (Erioderma pedicellatum) at Sixth Lake, Nova Scotia, in 2004. At least 80% of arboreal gastropods observed at the site were the introduced species Arion subfuscus. Subsequent surveys at five other locations in Nova Scotia showed 90% of arboreal gastropod individuals observed were introduced species. Potential impact on native lichen species, and in particular on rare and endangered species, is discussed.

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]

Abstract. The article presents the results of an experimental assessment of the peculiarities of the water regime of 9 species of the genus Iris L. growing in the South-Ural Botanical Garden-Institute UFRC RAS (I. sibirica L., I. pseudacorus L. ‒ species of native flora, I. aphylla L., I. biglumis Vahl., I. lacteal Pall., I. orientalis Mill., I. ruthenica Ker-Gawl., I. setosa Pall., I. spuria L. ‒ introduced species). The purpose is a comparative evaluation of the main parameters of the water regime within the generic complex and depending on the detection of meteorological factors in different phenological periods. Methods. Studies were performed in growing periods 2019–2020’s physiological using conventional techniques (artificial saturation method and wilting). Made a detailed analysis of daily and seasonal dynamics of the water regime of the three parameters: the total water content, water-holding capacity, water scarcity. Typical forest species Convallaria majalis L. was investigated for a comparative analysis of water regime indicators. Results. The similarities and differences in the peculiarities of the water regime were established between the studied species, the dependence of the indicators on meteorological conditions was revealed. According to the type of water regime cultivars were divided into four groups: a flexible water-quiet mode ‒ I. pseudacorus, flexible water-tight mode ‒ I. sibirica, I. ruthenica, stably-calm water mode ‒ I. aphylla, I. biglumis, I. setosa, stably-tight water mode ‒ I. spuria, I. lactea, I. orientalis. Among the studied parameters of water scarcity was the most dependent on meteorological factors. Scientific novelty. The study helps to identify ecological and physiological adaptations of exotic species in comparison with the native species that could become the basis for assessing the prospects of growing in the culture and conservation of rare and endangered species.
