Mycobiota of the Zailisky Alatau includes 176 species of rust fungi, the Microbotryomycetes class has 5 species, the Pucciniomycetes class is represented with 171 species. The largest number of species is characteristic of the genera Puccinia (98 species) and Uromyces (24 species). Others genera are represented with 1-13 species. The greatest number of species of rust fungi is noted for altitudes of 1700-1900 and 1900-2100 m above sea level, what correlates with the vegetation zone of dark coniferous forests and meadows. Great aridity does not allow fungi to develop intensively in the lower foothills and steppe zone, and low temperatures and intense solar insolation inhibit the development of rust fungi in the alpine and subalpine zones. 337 plant species from 165 genera are registered as host plants. The largest number of rust fungi species is noted in the Small and Big Almaty gorges (73 and 57 species, respectively), in the Talgar and Turgen gorges (57 and 63 species, respectively). The gorges of Karakastek, Ush-Konyr, Uzyn-Kargaly, Chemolgan, Small Kemin and Oi-Karagai are characterized by an insignificant diversity of rust fungi (from 3 to 8 species), which is associated with lower humidity of these gorges.

A list of the genus Betula L. was compiled by the authors on the basis of field work carried out in 1970–2019, and also the collections of other collectors stored in the herbarium of Republican state-owned enterprises on the right of economic management “Altai Botanical Garden” (Ridder) and the Institute of Botany and Phytointroduction (Almaty). Purpose: to clarify the species composition and distribution of the genus Betula L. (family Betulaceae S.F. Gray) in the territory of Kazakhstan Altai, the Altai ridges and the Zaysan depression. As a result of the studies established the growth of 15 species and one subspecies of the genus Betula L. in the studying region. The study of herbarium samples, literature data and private collections allowed to supplement the species composition of the genus Betula L. of Kazakhstan with 7 species: B. x aurata Borkh., B. pseudopendula V. Vassil., B. falcata V. Vassil., B. x kelleriana Sukacz., B. х pseudomiddendorffii V. Vassil., B. talassica P. Pol., B. fruticosa subsp. montana M. Schemberg. Species saturation in the studied region: Central Altai – 3 species (18,8% of the total number of species); Southern Altai – 11 (68,75%); Western Altai –11 (68.75%); Kalba Altai – 6 (37,5%); Zaysan depression – 3 (18,75%); Saur-Manrak – 2 (12,5%). The average saturation index of species of the genus Betula L. in the flora of the Kazakhstan Altai and the Altai ranges is 6, which is relatively low, which indicates that family Betulaceae in the studied region is a specific element of boreal and holarctic flora. Keywords: list, genus Betula, species, Kazakhstan Altai, Saur-Manrak, Zaysan depression, distribution, occurrence.

Abstract Species composition and host associations of the aphidiid wasps infesting aphids in Kyiv, Cherkasy, Poltava and Kirovohrad Regions of the Central Wood-and-Steppe Zone of Ukraine were studied during 2010-2011, mainly on meadows. Nine species of aphids were found on 36 plant species, of them 7 species were infested by aphidiids. Six species of parasites were reared: Lysiphlebus fabarum (Marshall), L. confusus Tremblay et Eady, L. fritzmuelleri Mackauer, Lipolexis gracilis Förster, Binodoxys acalephae (Marshall), B. angelicae (Haliday). The most widespread species were L. fabarum and L. confusus. The rate of aphids colony infestation according to weather conditions and association with host plants are discussed. An illustrated key to the found species is given.

This paper exhibites species composition and distribution of marine seaweed at 10 sites of Co To and Thanh Lan islands in May 2019. The studies record 76 species of marine algae in the area, belonging to four divisions: Cyanophytes, Rhodophytes, Ochrophytes and Chlorophytes. Among them, five species are classified into Cyanophytes (comprising 6.6% of total species); thirty-four species into Rhodophytes (44.7%); twenty-one species into Ochrophytes/Phaeophytes (27.6%) and sixteen species into Chlorophytes (21.1%). The species composition of marine seaweeds in Co To and Thanh Lan shows significant differences as follows: 22 species (sites number 4 and 10) to 58 species (site number 2) and the average value is 38.7 species per site. Sørensen similarity coefficient fluctuates from 0.33 (sites number 5 and 10) to 0.84 (sites number 1 and 3) and the average value is 0.53. The current investigations show that four species of twenty-one species are collected in the littoral zone and forty-two species in the sub-littoral zone (in which there are thirteen species distributed in both littoral zone and sub-littoral zone). The algal flora in Co To and Thanh Lan is characterized by subtropics.

Вертикальное озеленение с участием различных видов лиан в современных условиях имеет важное эстетическое и санитарно-гигиеническое значение. Особо актуально решение вопросов обогащения флоры городских территорий лианами в степных районах в связи с бедным видовым составом и резким ухудшением экологической ситуации. Объектами исследований являлись 7 видов лиан, различных жизненных форм (однолетние, многолетние), произрастающие в населенных пунктах Саратовской области (Аткарск, Саратов). Цель исследований – изучение эколого-биологических особенностей и мелиоративных свойств лиан и выявление перспектив их использования в вертикальном озеленении селитебных территорий Саратовской области. В ходе исследования видового состава, были выявлены наиболее популярные виды однолетних лиан: ипомея красно-голубая (Ipomea tricolor (L.) Roth) и ипомея пурпурная (Ipomea purpurea (L.) Roth), горошек душистый (Lathyrus edoratus L.), настурция (Tropacolum peregrinum L.) и фасоль огненно-красная (Phaseolus coccineus). Большинство (70%) из них произрастают в местах ограниченного пользования. Изученные виды лиан в исследуемых регионах достигают средних природных показателей (при наличии надлежащего ухода), обладают хорошими показателями жизненного состояния, обильно цветут и плодоносят. При воздействии токсикантами различной концентрации на листовые пластинки лиан установлено их степень устойчивости. Выявлено, что однолетние лианы лучше использовать в декоративных целях, а не в санитарно-гигиенических. Сравнительная оценка однолетних видов с многолетними лианами (девичий виноград пятилисточковый и клематис тангутский) показывает устойчивость многолетних видов (в среднем на 3 балла - 40%). Разработаны варианты декоративных композиций с участием травянистых лиан. По степени декоративности выделены однолетние лианы – Ipomea tricolor, I. purpurea (37 – 41 балл), средней степенью отличаются – Lathyrus edoratus (33 балла), Tropacolum peregrinum (30 баллов) и Phaseolus coccineus (20 – 27 баллов). Преимущество многолетних лиан заключается в их устойчивости к резким изменениям климатических условий (на 40 %) по сравнению с однолетними формами. Поэтому они более предпочтительны для озеленения городской среды. Для усиления декоративного эффекта в сезонном аспекте рекомендуются сочетать расширение видового и формового разнообразия растений (многолетние и однолетние лианы, древесно-кустарниковая, цветочная растительность). Установлено, что природно-климатические условия зоны степи и лесостепи в пределах Саратовской области являются достаточно благоприятными для нормального роста и развития древесно-кустарниковой растительности, в том числе травянистых лиан. Таким образом, обоснованное применение древесных лиан в комплексе с традиционными видами насаждений позволит создать комфортные условия проживания населения, регулировать оптимальный температурный баланс и создавать благоприятные микроклиматические условия. Vertical gardening with different types of vines in modern conditions is important aesthetic and sanitary-hygienic value. It is especially important to address the issues of enrichment of the flora of urban areas with vines in the steppe regions due to poor species composition and a sharp deterioration of the ecological situation. The objects of research were 7 species of lianas, various life forms (annual, perennial), growing in the settlements of the Saratov region (Atkarsk, Saratov). The aim of the research is to study the ecological and biological features and reclamation properties of vines and identify the prospects for their use in vertical gardening residential areas of the Saratov region. In the study, species composition was the most popular species of annual vines: morning glory red-blue (Ipomea tricolor (L.) Roth) and purple morning glory (Ipomea purpurea (L.) Roth), the fragrant pea (Lathyrus edoratus L.), nasturtium (Tropacolum peregrinum L.) and runner beans (Phaseolus coccineus). Most (70%) of them grow in restricted areas. Studied species of vines in the study regions reach average natural performance (with proper care), have good indicators of vital condition, bloom abundantly and bear fruit. When exposed to toxicants of different concentrations on the leaf blades of vines established their degree of stability. It was revealed that the annual vines are better used for decorative purposes, and not in the sanitary-hygienic. A comparative assessment of annual species with perennial vines (maiden grapes and clematis Tangut) shows the stability of perennial species (an average of 3 points-40%). The options and decorative compositions with the participation of herbaceous vines. According to the degree of decoration of the allocated annual vine – Ipomea tricolor, I. purpurea (37 – 41 points), the average degree of differ – Lathyrus edoratus (33 points), Tropacolum peregrinum (30 points) and Phaseolus coccineus (20 to 27 points). The advantage of perennial vines is their resistance to sudden changes in climatic conditions (40 %) compared to annual forms. Therefore, they are more preferable for greening the urban environment. To enhance the decorative effect in the seasonal aspect, it is recommended to combine the expansion of species and form diversity of plants (perennial and annual lianas, tree and shrub, floral vegetation). It is established that the climatic conditions of the steppe and forest-steppe zone within the Saratov region are quite favorable for the normal growth and development of tree and shrub vegetation, including herbaceous lianas. Thus, the reasonable use of wood vines in combination with traditional types of plantings will create comfortable living conditions for the population, regulate the optimal temperature balance and create favorable microclimatic conditions.
