Abstract

A field study of common ragweed (Ambrosia artemisiifolia L.) in European Russia provided information on the occurrence and abundance of the species and enabled a prediction of the possible boundaries of species naturalization. As a result, the understanding of the ecological limits of common ragweed distribution related to the limiting environmental factors was refined. Insufficient heat supply during the seed ripening period is the factor that determines the expansion of the species to the north in European Russia. The moisture deficit factor determines the eastern and southeastern boundaries of species expansion. Ecological maps based on MODIS data from the Terra satellite were used in the ecological analysis of geographical distribution of the common ragweed. As a result, the map of the distribution potential of the common ragweed in European Russia was refined and the possibility of species naturalization in the area was plotted on the map.

评估豚草(Ambrosia artemisiifolia L.)的发生和丰度,并评估其在欧洲俄罗斯的扩张潜力

摘要

豚草(Ambrosia artemisiifolia)的田间研究。L.)在欧洲,俄罗斯提供了有关物种发生和丰度的信息,并能够预测物种归化的可能边界。结果,加深了对与豚草分布相关的生态极限的认识,这些生态极限与有限的环境因素有关。种子成熟期供热不足是决定该物种向欧洲北部北方扩张的因素。水分亏缺因子决定物种扩展的东部和东南边界。将基于Terra卫星MODIS数据的生态图用于常见豚草地理分布的生态分析。结果是,
