Abstract

Water caltrop Trapa natans L. is a relic aquatic plant protected in 36 regions of Russia. The most northern and isolated populations of this plant in Southern Ural and Altai are poorly studied. The results of a chemical analysis of water and aquarium culture experiments revealed that this plant could tolerate a wide range of environmental factors. The species appear to be sensitive to chlorides and low water temperatures, but resistant to sulfate salinization. Human factors are the main threats to the northern populations of water caltrop, which in Altai has already resulted in the extinction of this plant in Lake Aya and population declines in lakes Manzherok and Kanonerskoye.

栖息地北部边界的菱角菱Tra的生长条件

摘要

菱角菱pa属水生植物是在俄罗斯的36个地区受到保护的水生植物。对这种植物在乌拉尔南部和阿尔泰南部最北部和最偏远的种群的研究很少。对水和水族馆养殖实验进行化学分析的结果表明,该植物可以耐受多种环境因素。该物种似乎对氯化物和低水温敏感,但对硫酸盐碱化具有抵抗力。人为因素是对北方水cal种群的主要威胁,在阿尔泰,这已经导致该植物在阿亚湖灭绝,Manzherok和Kanonerskoye湖的种群减少。
