Мey.) G. Don fil и посвящена исследованию пространственного размещения особей вида в различных экологических условиях на 6-и модельных площадках в нижних предгорьях Дагестана.</p><p>Определение типа пространственного размещения было проведено с применением метода квадратов и подтверждено статистическими тестами Хи-квадрат и индекс Одума.</p><p>Выявлено, что на территории произрастания особи Nonea decurrens размещены контагиозно. При обследовании заложенных профилей на постоянных площадках выявлены элементарные мелкие и объединенные крупные скопления особей изучаемого вида разных возрастных состояний (прегенеративные и генеративные). Популяционная плотность Nonea decurrens на территории произрастания вида составила 0.65 шт/м2, протяженность элементарных скоплений на профилях — 8.9 м, а плотность особей в них — 30,4 шт/м2. Протяженность промежутков между скоплениями составила 1,1 м, а плотность особей здесь — 0.16 шт/м2. Дискретность скоплений установлена на уровне 0.97, что обнаруживает четкое отграничение таковых друг от друга, а степень отдаленности скоплений (0.3) демонстрирует групповой тип размещения особей изучаемого вида на всех модельных площадках.</p></abstract><trans-abstract xml:lang="en"><p>This work was carried out within the framework of a long-term comprehensive study of the endemic species of the Eastern Caucasus — Nonea decurrens (С.А. Мey.) G. Don fil and is devoted to the study of the spatial accommodation of individuals of the species in various ecological conditions on 6 model areas in the lower foothills of Dagestan.</p><p>Determination of the type of spatial accommodation was carried out using the method of squares and confirmed by the statistical tests Chi-square and Odum's index.</p><p>It was revealed that, individuals of Nonea decurrens are accommodation in groups on the territory of growth. When examining the established transects on permanent areas, elementary small and united large accumulations of individuals of the studied species of different age states (pregenerative and generative) were revealed. The population density of Nonea decurrens in the area where the species grows was 0.65 pieces / m2, the length of elementary aggregations on transects was 8.9 m, and the density of individuals in them was 30.4 pieces / m2. The length of the intervals between the accumulations was 1.1 m, and the density of individuals here was 0.16 pcs / m2. The discreteness of accumulations is set at 0.97, which reveals a clear delimitation of those from each other, and the degree of remoteness of accumulations (0.3) demonstrates the group type of accommodations of individuals of the species under study at all model areas.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Nonea decurrens</kwd><kwd>популяционные исследования</kwd><kwd>пространственное размещение</kwd><kwd>редкие виды</kwd><kwd>Предгорный Дагестан</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Nonea decurrens</kwd><kwd>population studies</kwd><kwd>spatial accommodation</kwd><kwd>rare species</kwd><kwd>Foothill Dagestan</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Атаев З.
