The lawn coverings creation in the humid subtropics zone of Russia is one of the topical areas of ornamental horticulture. This is due to the high requirements for year-round decorative plantings, the peculiarities of natural and climatic conditions and the general lack of issue knowledge. This direction is of particular importance in plantations located in shaded areas under the canopy of tree crowns, where, in addition to common for the region unfavourable factors of the hydrothermal regime, insufficient illumination is added, which together limits the possibility of traditional cereal grasses cultivating. Evergreen grass-like ground cover plants can be a complete substitute for lawn grasses in shaded areas. The aim of the research was to determine the degree of drought resistance of Liriope graminifolia (L.) Baker and Ophiopogon japonicus (Thunb.) Ker Gawl. and the ability to maintain decorativeness during the period of unfavourable hydrothermal conditions in the summer in the humid subtropics of Russia. The studies were carried out in 2013-2018 on the Black Sea coast of the Caucasus in the Sochi region, in plantations (on test plots with an area of 5-10 m2) and in conditions of vegetation experiments (in containers with a volume of 2 liters) on the territory of the Kuban Subtropical Botanical Garden (settlement Uch-Dere), according to generally accepted methods adapted to the studied taxa. It was found that an important mechanism of adaptation of the studied plants to drought is the ability to accumulate and redistribute moisture between vegetative organs, providing a high water content in the leaves. The decorativeness of O. japonicus and L. graminifolia in open ground in the atmospheric moisture absence lasts up to 12-14 days, in a vegetation experiment (container culture) – up to 14-16 days. O. japonicus and L. graminifolia retained the ability to self-regenerate up to 35-37 days of the experiment, and then the plants died. The consequences of summer drought in the studied plants were compensated by active autumn growth. Unlike classic lawns, which require daily watering, lawns from O. japonicus and L. graminifolia should be irrigated with a long (more than 12-14 days) absence of precipitation in the summer months.

Влажные субтропики Черноморского побережья России являются региономреципиентом для большого количества инвазионных видов вредных организмов. В начале XXI в. в зоне влажных субтропиков России выявлены 35 новых видов дендрофильных насекомых, из которых 26 можно отнести к инвазионным: из них 17 видов новые для территории России, а 9 новые для субтропической зоны Черноморского побережья Кавказа. Особенности инвазионного процесса у фитофагов изучались на основе анализа таксономического состава, регионовдоноров, векторов и путей инвазии, биотопического распределения видов и динамики инвазий. За период 2000 2017 гг. в общем количестве появившихся инвазионных видов отмечено снижение доли представителей отряда Hemiptera и увеличение доли представителей отряда Lepidoptera. В последние годы наибольшее количество инвазионных видов вредителей имеет североамериканское, а не восточноазиатское происхождение, что было характерно для региона на протяжении предыдущих полутора столетий. Установлены векторы инвазии для новых видов: непреднамеренный завоз с посадочным материалом, проникновение с транспортными потоками, непреднамеренный завоз с грузами нерастительного происхождения, самостоятельные перелеты. Все инвазионные виды восточноазиатского, американского и австралийского происхождения характеризуются двухступенчатой инвазией, т. е. они проникали в Россию из вторичного ареала в Европе. Максимальное количество чужеродных видов обосновалось в насаждениях декоративных пород (садовопарковые экосистемы), причем эта тенденция традиционна для региона. Частота появления инвазионных видов на Черноморском побережье Кавказа в начале XXI в. 1 вид в 9 месяцев, что в 7,4 раза чаще, чем в начале XX в. Humid subtropics of the Russian Black Sea coast are the recipient region for many invasive species of harmful organisms. At the beginning of the XXI century, 35 new species of dendrophilous insects were identified in the humid subtropical zone of Russia, 26 of which can be considered invasive: 17 species are new for Russia and 9 are new for the subtropical zone of the Black Sea coast of the Caucasus. Special features of the invasive process among phytophages were studied using following parameters: taxonomic composition, donor regions, vectors and pathways of invasion, biotopic distribution of the species and invasion dynamics. During the period of 2000 2017, a decrease in the representatives of order Hemiptera and an increase in the representatives of order Lepidoptera has been recorded. In recent years, the largest number of invasive species has North American origin rather than East Asian, which was typical for the region over the previous one and a half centuries. The following invasion vectors were specified for the newly recorded species: unintentional importation with planting material, invasion with traffic flow, unintentional importation with goods of nonplant origin, independent migration. All invasive species of East Asian, American, and Australian origin are characterized by twostage invasion, namely arriving to Russia from the secondary invasive range in Europe. The maximum number of alien species has settled in the plantations of ornamental species (landscape ecosystems), and this trend is traditional for the region. The rate of invasive species on the Black Sea coast of the Caucasus in the early XXI century was once in nine months, which is 7,4 times higher than in the early XX century.

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.
