Abstract
Poisonous plants are a collective group of plants of various systematic categories that contain phytotoxins that pose a potential danger to humans and animals. A number of publications both in Russia and abroad are devoted to the problem of patterns of distribution of plants hazardous to human health in connection with environmental factors. This work is a continuation of research into the spread of plants dangerous to humans in Russia. The aim of this work is ecological and geographical analysis of poisonous plants distribution in biomes of the Far East in Russia. Resulted from the research work on the territory of the far-eastern biomes of Russia we revealed 87 the most toxic vascular plant species that belong to 21 plant families. Some of the most poisonous plants of the Russian flora are plants of the genus Aconitum, of the family (Ranunculaceae). About 70 species of this genus grow in Russia, of which 40 are found only in the Far East, since this territory is considered the center of botanical diversity of the genus in question. The cartographical analysis showed that the highest number of poisonous plant species could be found in the south-east regions – in Primorye, the basin of Ussuri river, in the lower and middle course of the river Amur. Based on a map of Russian biomes, optimal habitats for poisonous plants were identified. Maximum number of Aconitum species, as the most poisonous genus of Russian flora, is in the mountain biomes and in the plain forest-steppe biomes in the Amur basin. The types of ecosystems with the maximum abundance and diversity of poisonous plants have been identified. The species richness distribution shows the concentration of poisonous plant species in small mountain biomes and in arid-like biomes. Correlation analysis of relationships between the number of plant species and climatic factors revealed the significant closeness of the correlation with the average annual air temperature (0,66). Maximum correlation closeness appeared to be between number of poisonous plant species per 10 000 km 2 and total number of vascular plants per 10 000 km 2 (0,81).
期刊介绍:
Journal “GEOGRAPHY, ENVIRONMENT, SUSTAINABILITY” is founded by the Faculty of Geography of Lomonosov Moscow State University, The Russian Geographical Society and by the Institute of Geography of RAS. It is the official journal of Russian Geographical Society, and a fully open access journal. Journal “GEOGRAPHY, ENVIRONMENT, SUSTAINABILITY” publishes original, innovative, interdisciplinary and timely research letter articles and concise reviews on studies of the Earth and its environment scientific field. This goal covers a broad spectrum of scientific research areas (physical-, social-, economic-, cultural geography, environmental sciences and sustainable development) and also considers contemporary and widely used research methods, such as geoinformatics, cartography, remote sensing (including from space), geophysics, geochemistry, etc. “GEOGRAPHY, ENVIRONMENT, SUSTAINABILITY” is the only original English-language journal in the field of geography and environmental sciences published in Russia. It is supposed to be an outlet from the Russian-speaking countries to Europe and an inlet from Europe to the Russian-speaking countries regarding environmental and Earth sciences, geography and sustainability. The main sections of the journal are the theory of geography and ecology, the theory of sustainable development, use of natural resources, natural resources assessment, global and regional changes of environment and climate, social-economical geography, ecological regional planning, sustainable regional development, applied aspects of geography and ecology, geoinformatics and ecological cartography, ecological problems of oil and gas sector, nature conservations, health and environment, and education for sustainable development. Articles are freely available to both subscribers and the wider public with permitted reuse.
