摘要

建立了跨贝加尔湖东南部36种小型兽类的分布模型。环境因素(气候数据和地球表面遥感)在每一物种被捕获的一组地点的分布被作为建模的初始数据。36个案例中只有30个案例可以用环境因子的分布来解释物种的分布范围。其中的17种只能用一两个环境因素来解释。在6个案例中，发现了历史因素或种间竞争对目前物种分布的显著影响。对于这6个物种，建模结果使我们能够提出关于目前分布背后原因的假设，而没有建模方法是无法提出这些假设的。

[A study of the distribution ranges of small mammals from South-Eastern Transbaikalia with ecological niche modeling methods].

Distribution models were constructed for 36 species of small mammals from South-Eastern Transbaikalia. Distribution of environmental factors (climatic data and remote sensing of the earth surface) in the set of localities where each of the species was caught was taken as initial data for modeling. Species distribution ranges can be explained by distribution of environmental factors only in 30 cases out of 36. Seventeen of them can be explained by one or two environmental factors only. In 6 cases notable influence of historical factors or interspecific competition on present species distribution was found out. For these 6 species, modeling results make it possible to suggest hypotheses about reasons behind present distribution, which could not be advanced without modeling approach.

期刊介绍： Публикуются статьи по теоретическим вопросам биологии, представляющие интерес для биологов любой специальности (вопросы эволюции, экологии, общей таксономии, общей цитологии, генетики, проблемы механизмов приспособления живых организмов к условиям существования, закономерности развития организмов, бионика и т. д.), основанные на новом оригинальном фактическом материале или же подводящие итоги работы того или иного научного коллектива. Помимо теоретических статей, помещаются рецензии на новые книги российских и зарубежных биологов, а также информация о международных конгрессах и общероссийских совещаниях по важнейшим проблемам биологии.
