“…Вибір місця дослідження G. squarrosa для популяційних досліджень зумовлений тим, що саме Старобільський злаково-лучний степ є одним із первинних осередків занесення виду в Україну та його сучасним високим інвазійним статусом (Kucher 2015). Дослідження інвазійних видів на популяційному рівні дає можливість з'ясувати особливості біології та специфіку їх адаптації в нових умовах, що дозволить прогнозувати подальше поширення та можливості участі у різних типах рослинних угруповань.…”

Specifics of the ontogenesis of Grindelia squarrosa in populations from eastern Ukraine. -O. Kucher. -Results of studying of the ontomorphogenesis of the North American adventive species G. squarrosa in its secondary range in natural conditions of eastern Ukraine are presented. The scheme of ontomorphogenesis is given and age states are selected (seeds, seedlings (p), juvenile (j), immature (im), virginal (v), young generative (g1), medieval generative (g2), aging (g3), subsenile and senile plants) and their characteristics are presented. It was found that the number of seedlings differs significantly during the growing season, the germination of seeds is also affected by temperature, the largest number of seedlings is observed at values from +25 to +27 C˚ in the spring. The choice of the study site is not accidental -the locality of the species in the Starobilsk grass-steppe meadow of Luhansk Oblast in the floodplain of the Siversky Donets River is one of the primary centres of deposition and distribution of G. squarrosa and its current high invasive status. The research was conducted according to the generally accepted methods of Zlobin at four localities. The density, ontogenetic and vitality structure of populations were studied. Each population was surveyed five times a year at the beginning (end of May) in the middle (June; early and late July) and at the end of the growing season (September). It was determined that the species is characterised by non-simultaneous germination of seeds and the formation of monodominant groups; the species acts as a co-dominant in steppe groups, prefers sandy loam and clayey loam and gravely soils, rarely occurs on gravel and dense clay substrate. The period of ontogenetic development of the studied species lasts 1-2 years. As a result of studying the ontogenetic structure of model populations of G. squarrosa, it was found that they are dominated by plants of pregenerative state, i.e. the spectrum of age groups is left-sided, characterised by positive asymmetry with peak on plants of younger age group, full-fledged populations and has high recovery indices.

A review of methods of investigation of alien plant species. -L. Zavialova. -The assessment of alien and invasive alien species (IAS) in the plant cover of protected areas (PAs) of Ukraine becomes a new trend of research, especially when invasions have turned into biological hazards for natural biodiversity, thus threatening its structure and ecosystems functioning. Taking into consideration the increasing spreading potential of IAS as well as the connection with their triggering environmental driving forces, even more current methods arose, mainly focusing on current distribution and its trends, abundance and its dynamics, potential impact on the environment and on some types of biotopes within PAs. In this study, a review of methods of field investigation of alien species is proposed for their inventory, monitoring, etc. and particularly for assessment of their impact within Ukrainian PAs. The choice of methods is determined in each case by the purpose and objectives of the study, taking into account the measures of management of PAs and some other factors, such as history, fragmentation of the object's territory, etc. Some methods focus on both complex and specialised research. Some of the methods were used earlier in studies of weeds, plant cover, biology or ecology of plants, etc. Other methods are new for the study of alien species in Ukraine. All of them are analysed and short adapted schemes or templates for plots are proposed. Some remarks about issues of their use are discussed. A few methods have been used for continuous monitoring of invasions of alien plants in PAs and can be integrated to the national Program of the Chronicle of Nature for Nature Reserves and National Nature Parks. All methods can be used for the study of alien, native and species with mixed status. The effectiveness of most of the methods depends on the sequence of execution, preparation, available resources of the researchers and PAs. The use of these methods will help to summarise data, record new finds, predict the spread of dangerous IAS, develop effective control measures and management of PAs, and integrate research results into databases of different levels.
