DYNAMICS OF THE VITALITY OF CENOPOPULATIONS OF HOLOSTEUM GLUTINOSUM (M. BIEB.) FISCH. & C.A. MEY. (CARYOPHYLLACEAE) IN THE ECOTONE SYSTEM “WATER-LAND” OF THE COAST OF THE CHOGRAI RESERVOIR

Background. The assessment of the structure cenopopulations early spring juveniles can be used during organization biological monitoring at population level. Such information is also applicable in assessing situation coastal ecosystems, for forecasting and reducing risk their violations.
 Purpose. Analysis viability Holosteum glutinosum to characterize stability plant communities “water-land” ecotone system coast Chograi reservoir.
 Materials methods. studies were carried out growing seasons 2018, 2019 2021 five coenopopulations H. located structural blocks ecotone.
 vital spectrum populations was obtained by method Yu.A. Zlobin [3, 10, 18], type - using Q criterion [3], vitality – based on analysis index IVC degree prosperity or depression IQ [4].
 Results. During four-year study period, 5 glutinosum, regardless localization ecotone, value exceeds frequency individuals lowest class vitality, therefore they are classified as “thriving” type.
 indices entire period greatest cenopopulation No. 1, fluctuation block. first peak increase occurred coenopopulation 1 fluctuation, second 4 marginal blocks.
 Conclusion. had a “thriving”. dynamics revealed that conditions prevailing provide 4.
