Abstract

Vaccinium vitis-idaeà L. is a widespread and dominant species of boreal forests. It has an important ecological role as a food source for humans and many species of animals, including birds. The aim of this study is to determine the ecological features and their influence on the ontogenetic structure of V. vitis-idaea populations in forest ecosystems of the southern taiga (Kirov oblast, Russia). V. vitis-idaea is a gemyeurybiotic species whose ecological space amplitude in Kirov oblast does not exceed the limits of Tsyganov’s ecological range scales (1983). The discomfort index calculated with phytoindication data made it possible to determine the level of favor. We have determined that conditions of swampy pine forest (CP 2, 5) have optimum ecological parameters for species growth. The least favorable conditions for V. vitis-idaea development are formed in the herbaceous birch forests and green moss spruce forest (CP 4, 10), where maximum discomfort indices are marked: 1.08. All populations under study are normal and incomplete. Pregenerative individuals are stable and often dominate. Generative plants, which are absent in some populations (CP 10), are less constant. The dominant specter type of the populations is bimodal. The index of substitution states that prospective populations prevail in the study, except for population 3, which was unstable and ineffective in self-renewal. Delta-omega classification shows that young populations prevail in the study. The ecological conditions of the studied phytocoenoses affect the ontogenetic parameters of V. vitis-idaea plants. The quantity of the young generative age group depends on the soil moisture (r = 0.76) and the soil-moisture variability (r = –0.68); pregenerative age groups depend on illumination (r = 0.74). A high level of significance was revealed between the age index, the replacement index, the coefficient of vegetative self-maintenance, and the illumination of the habitat.

生态因子对俄罗斯东北欧洲森林生态系统越桔越桔种群种群遗传学参数的影响

摘要

越桔（Vacciniumvitis-idaeàL .）是北方森林的一种广泛存在的优势种。它作为人类和许多动物（包括鸟类）的食物来源具有重要的生态作用。这项研究的目的是确定在南部针叶林（俄罗斯基洛夫州）的森林生态系统中，葡萄的生态特征及其对葡萄亚科种群的个体发育结构的影响。葡萄科是一种胚生生物物种，其在基洛夫州的生态空间幅度未超过Tsyganov生态范围尺度（1983）的限制。用植物指示数据计算的不适指数使确定偏爱水平成为可能。我们已经确定，沼泽松树林（CP 2、5）的条件对于物种生长具有最佳的生态参数。葡萄球菌的最不利条件草本白桦林和绿色苔藓云杉林（CP 4，10）中形成了发育，其中最大不适指数标记为：1.08。所有接受研究的人群都是正常且不完整的。繁殖个体很稳定，经常占主导地位。在某些种群中不存在的可再生植物（CP 10），稳定性较差。种群的主要幽灵类型是双峰的。替代指数表明，预期人群在研究中占优势，但人群3不稳定且自我更新无效。三角洲-欧米茄分类显示年轻人群占主导地位。研究的植物表皮酶的生态条件影响葡萄-葡萄科的个体发育参数植物。年轻的成年年龄组的数量取决于土壤湿度（r = 0.76）和土壤水分的变异性（r = –0.68）；生殖年龄组取决于光照（r = 0.74）。在年龄指数，替代指数，植物自我维持系数和栖息地照度之间显示出很高的意义。
