КОМПЛЕКСНИЙ ПОПУЛЯЦІЙНИЙ АНАЛІЗ ЯК ТЕОРЕТИЧНА ТА МЕТОДОЛОГІЧНА ОСНОВА ОРГАНІЗАЦІЇ ОХОРОНИ ПРИКРІПЛЕНИХ ПТОЛОФІТІВ
Journal Title: Питання біоіндикації та екології - Year 2015, Vol 20, Issue 1
Abstract
The results of complex population analysis had been used for development the original methodic for differentiation of the rooted ptolophits’ populations (Nuphar lutea, Nymphaea candida, Nymphoides peltata, Trapa natans, Potamogeton natans) for a few categories. After has been highlighted a few categories: those which have the biggest potential to survive and those which do not have it. According to the Vitality analysis which uses the common division of thriving, balanced and depressive, populations had been divided into few categories. Based on number of individuals of different ontogenetic types in population’s structure populations have been divided into next categories: A – dominated individuals beforegenerative ontogenetic condition, B – generative ontogenetic condition, C – senile ontogenetic condition. After compounding those graduations of ontogenetic and vitality structures of populations has been highlighted nine quality groups. Populations of different quality groups have following features. Populations of 1A group are invasive in ontogenetic structure and mainly have high vitality individuals. Group 1B has individuals in generative ontogenetic condition with high vitality. Populations of group 1C are regressive in ontogenetic structure, aging processes dominate the growing processes here. But individuals mainly have high vitality. Populations of 2A group are invasive in ontogenetic structure with same numbers of individuals with high, interim and low vitality. In structure of population of 2B group generative condition individuals are dominating. The numbers of individuals with high, interim and low vitality are almost the same. In populations of group 3B aging processes dominate the growing processes but the numbers of individuals of all vitality categories are the same. Populations of 3A group are invasive in ontogenetic structure but low vitality individuals are dominating. In structure of population of group 3B individuals in generative ontogenetic condition and low vitality are dominating. In populations of group 3C aging processes dominate the growing processes and individuals mostly have low vitality. The analysis showed significant part (55,6 %) of the studied population of the rooted ptolophits belongs to the groups which have high potential for continued existence (1A, 1B, 2A, 2B). Shown, that it is actual to provide the system of monitoring into the range ofmeasures of protection for all populations. For the populations which belong to groups 3A and 3B stabilization of the water regime of the pond is very important. Опираясь на результаты комплексного популяционного анализа было предложено оригинальную методику дифференциации популяций прикрепленных птолофитов на девять качественных групп на основе учета показателей их виталитетной и онтогенетической структуры. Определено характерные показатели популяций, которые репрезентуют каждую из девяти групп и базовые позиции организации охраны прикрепленных птолофитов в зависимости от качественного статуса их популяций.
