Охарактеризовано величини 14 статичних метричних та шести статичних алометричних морфопараметрів рослин Oxycoccus palustris Pers. у чотирьох фітоценозах Українського Полісся. Показано, що особини з різних рослинних угруповань статистично достовірно відрізняються між собою величинами майже всіх розмірних показників. Установлено, що значення більшості статичних метричних морфопараметрів у рослин Oxycoccus palustris зростають у такій послідовності екоряду фітоценозів: Betuleto (pubescentis)–Pinetum (sylvestris) vaccinioso (myrtilli)–sphagnosum (cuspidatі) Betuleto (pubescentis)–Pinetum (sylvestris) eriophoroso (vaginati)– sphagnosum (cuspidatі) Pinetum (sylvestris) sphagnosum (cuspidatі) Sphagnetum (cuspidatі) eriophorosum (vaginati). Доведено, що в кожному фітоценозі формуються особини зі специфічною морфоструктурою. Для досліджуваних угруповань визначено характерні морфоознаки рослин Oxycoccus palustris та побудовано їхні морофограми. Has been characterized the magnitude of the 14 static metric and six static alometric indices of morphological parameters of the plant Oxycoccus palustris Pers. in the four phytocenoses within Ukrainian Polissya. Has been shown that individuals from different phytocenoses significantly differ in the values of the absolute majority of size indicators. It is established that the value of static metric morphoparameters Oxycoccus palustris plants grow in the order an ecological series plant communities: Betuleto (pubescentis)–Pinetum (sylvestris) vaccinioso (myrtilli)–sphagnosum (cuspidatі) Betuleto (pubescentis)–Pinetum (sylvestris) eriophoroso (vaginati)– sphagnosum (cuspidatі) Pinetum (sylvestris) sphagnosum (cuspidatі) Sphagnetum (cuspidatі) eriophorosum (vaginati). Each phytocenosis formed individuals with a specific morphostructures. For the studied communities has been identified specific morfocharacters of Oxycoccus palustris plants and constructed their morfohrams.

Aim: to establish typical features of ontogenetic and vitality structures of Scilla bifolia coenopopulations in different phytocenoses in the Sumy geobotanical region, to evaluate the dynamics of these structure types in the period 2015–2016 years.Methods: Common geobotanical methods were used at the research. For the determination of ontogenetic spectrums of Scilla bifolia cenopopulations was used ANONS 6 non-commercial program, and for the determination of vitality spectrums and quality types of coenopopulations was used VITAL non-commercial program, elaborated by Y.A. Zlobin.Result: ontogenetic spectrums of all studied Scilla bifolia coenopopulations are bimodal by the one peak on juvenile or immature individuals and the other peak on young generative individuals. According to T.O. Rabotnov classification, all coenopopulations in 2015 were invasive, and in 2016 P1 and P2 remained invasive and P3 became normal. According to L.O. Zhukova classification, all Scilla bifolia coenopopulations in both 2015 and 2016 represented the normal group, and according to L.V. Zhyvotovsky classification, they are all young, because ∆/ω ratio for the period of researches in Scilla bifolia coenopopulations corresponded to the diapason from 0,06/0,20 to 0,18/0,52.As to the vitality analysis of Scilla bifolia coenopopulations, two qualitative types of this variety coenopopulations are presented: prospering and balanced.The common feature of the vitality structure of all coenopopulations Scilla bifolia is rather low (up to 13 %) part of individuals of the mean («b») vitality class. For coenopopulations P1 and P3 during two years is typical the predominance of high vitality (class «а») individuals.Conclusions within the Sumy geobotanical region the typical feature of Scilla bifolia coenopopulations is similar ontogenetic spectrums. Active renewal processes and intensive introduction in forest groups are inherent to them.Vitality structure of Scilla bifolia coenopopulations changes at the transfer from one phytocenosis to another. It is an evidence of realization of the ability to adaptation and to adjustment to growth conditions, Визначено онтогенетичну структуру ценопопуляцій Scilla bifolia та проведено її інтегральну оцінку. Визначено віталітетну структуру трьох ценопопуляцій Scilla bifolia на території Сумського геоботанічного округу. Зроблено висновки про онтогенетичну та віталітетну структури ценопопуляцій Scilla bifolia, визначено перспективи подальших фітопопуляційних досліджень даного виду в типових лісових угрупованнях досліджуваного району.

Over the last two decades Kazach’ya Bay area has been subjected to intensive coastal development resulted in deterioration of the environment quality. Considering the fact that the anthropogenic impact has already led to degradation of the key macrophythobenthos communities at many sites of Sevastopol coast, the assessment of the current state of the bottom phytocoenoses in Kazach’ya Bay is of great importance. The aim of the study was to investigate the species composition and quantitative parameters of the macrophytobenthos in Kazach’ya Bay and to analyze long-term changes in its bottom vegetation. Investigation was carried out in the western branch of the bay in September 2017 at depth of 3, 5, 6, 8 and 17 m; 41 macrophyte species were identified: 13 – Chlorophyta, 1 – Charophyta, 10 – Phaeophyceae, 13 – Rhodophyta, and 4 – Angiospermae. Such species as Chaetomorpha gracilis, Cladophora vagabunda, Lamprothamnium papulosum, Myrionema strangulans were recorded for the first time. Zostera noltii + Stuckenia pectinata phytocoenosis with biomass 905 g·m-2 was found at 3 m depth on the soft bottom, at 6 and 8 m it was replaced by monodominant Zostera noltii communities with biomass 691 and 390 g·m-2 respectively. At 5 m depth where alongside with soft sediments hard substrata occur, mosaic of patches dominated by Zostera noltii and Cystoseira crinita with mean biomass 1017 g·m-2 was found. Phyllophora crispa phytocoenosis with the biomass 290 g·m-2 was registered near the mouth of the bay at the depth of 17 m. Between 1999 and 2017 biomass of the seagrass communities decreased 2–3 times, moreover, Zostera marina phytocoenoses were replaced by the Zostera noltii dominated communities. Biomass of the Phyllophora community almost doubled over the same period.

The structure of 11 coenopopulations (CP) of Conioselinum tataricum Hoffm (Apiaceae) in tallherbaceosus phytocenosis of Salair ridge (south of West Siberia) was studied. The CP are generally of normal type. CP density is the highest in forest-tall-herbaceosus meadows. C. tataricum is the coenotical patient in plant communities. The biological and CP-stucture peculiarities show the low growth adaptation of C. tataricum in tall-herbaceosus phytocenosis of Salair.
