Abstract

This study is focused on soil nematode communities in undercrown areas of tree plants introduced to and cultivated for a long time in the botanical garden on Bolshoy Solovetsky Island (Arkhangelsk oblast, Russia). Soil nematode communities of natural forests (pine-, spruce-, and birch stands) are studied as the control. The study has demonstrated that the taxonomic diversity and abundance of nematodes, as well as the proportion of plant parasites in the trophic structure of nematode communities in the soil under introduced trees, are higher compared to natural forests. The ecological indices (structure index SI and enrichment index EI) change nonuniformly and so have poor performance as tools for evaluating the consequences of the plant introductions for the soil ecosystem. Correlation analysis reveals a significant positive relationship between the content of carbon and nitrogen in soil and the absolute and relative abundance and the taxonomic diversity of plant parasites, as well as significant negative relationships between C : N and fungal feeders, as well as between the soil pH and the taxonomic diversity of nematodes and the relative abundance of bacterial feeders and EI. The entomopathogenic nematode Steinernema affine Bovien revealed on the island has been reported for the first time in Russia.

土壤线虫群落是否因亚北极地区引进树木和长期栽培而改变?
摘要 本研究的重点是 Bolshoy Solovetsky 岛(俄罗斯阿尔汉格尔斯克州)植物园引进并长期栽培的树木冠下区域的土壤线虫群落。天然林(松树林、云杉林和桦树林)的土壤线虫群落作为对照进行研究。研究表明,与天然林相比,引进树木下的土壤线虫群落中线虫的分类多样性和丰度以及植物寄生虫在营养结构中的比例都较高。生态指数(结构指数 SI 和富集指数 EI)的变化不均匀,因此作为评估植物引种对土壤生态系统影响的工具性能较差。相关性分析表明,土壤中的碳和氮含量与植物寄生虫的绝对丰度、相对丰度和分类多样性之间存在显著的正相关关系,C : N 与真菌食料之间存在显著的负相关关系,土壤 pH 值与线虫的分类多样性、细菌食料的相对丰度和 EI 之间也存在显著的负相关关系。岛上发现的昆虫病原线虫 Steinernema affine Bovien 在俄罗斯尚属首次报道。

期刊介绍: Contemporary Problems of Ecology is a multidisciplinary periodical that publishes original works on the following subjects: theoretical and methodical issues of ecology, regional aspects of ecology, regional ecological disasters, structure and functioning of ecosystems, anthropogenic transformation of ecosystems. All basic aspects of modern ecology, including the most complicated interactions between living organisms and their environment, are presented. Some of the journal issues are dedicated to global changes in biological diversity at various levels of organization (populations, species, ecosystems) principles and methods of nature conservation.
