Abstract

Studies in the fir‒spruce forests of the Middle Urals, in habitats with varying degrees of transformation by natural disasters (windfalls and fires), have shown that the abundance and dynamics of invertebrate communities determine the food supply of shrew habitats, one of the most important microhabitat characteristics. The indicator of food supply reflects the state of the foraging base of the common shrew and is a stable biotopic characteristic, the stability of which is maintained due to the redistribution of the abundance of different taxonomic groups of soil mesofauna in the course of their long-term dynamics. The abundance of the common shrew was not related to the food supply of the habitats of the current year, but depended on the food supply of the previous year, and this dependence was most pronounced in strongly disturbed habitats.

普通鼩鼱（Sorex araneus、Eulipotyphla）种群及其在生态对比环境中栖息地的食物供应

摘要

在中乌拉尔的冷杉林中，栖息地因自然灾害（意外和火灾）而发生不同程度的转变，研究表明，无脊椎动物群落的丰度和动态决定了鼩鼱栖息地的食物供应，鼩鼱栖息地是最重要的栖息地之一。重要的微生境特征。食物供给指标反映了鼩鼱觅食基地的状况，是一种稳定的生物群落特征，其稳定性是由于土壤中型动物群不同分类群在其长期生存过程中的丰度重新分布而得以维持的。术语动态。鼩鼱的丰度与当年栖息地的食物供应无关，而取决于前一年的食物供应，这种依赖性在强烈干扰的栖息地中最为明显。
