В 28 собранных пробах выявлено 55 видов и подвидов раковинных амёб, относящихся к 9 родам и 6 семействам. Видовое разнообразие раковинных амёб в планктоне выше, чем в донных пробах. Наибольшей частотой встречаемости характеризовались Centropyxis aculeata (64,3%), Netzelia wailesi (39,3%), Difflugia acuminata (32,1%), Arcella discoides scutelliformis (28,6%) и Lesquereusia modesta (28,6%). Наибольшим числом видов представлены роды Difflugia (25), Arcella (12), Centropyxis (5) и Netzelia (4). Кривая видового накопления, основанная на полученных данных, не насыщена и описывается уравнением y = 12,56N046. Среднее видовое богатство раковинных амёб на пробу в планктоне (13,0 ± 3,1) статистически выше, чем в донных пробах (1,8 ± 1,5) (p&lt;0,001). Результат ординации (анализ избыточности) показывает, что исследованные гидрохимические показатели (температура, pH, содержание растворенного кислорода, электрическая проводимость, соленость) воды объясняют лишь 31,6% вариации видового состава раковинных амёб, в том числе первая и вторая оси объясняют 11 и 10,2% вариации соответственно.</p></abstract><trans-abstract xml:lang="en"><p>First data on the species diversity of testate amoebae of the Coco River in the provinces of Quangnam and Danang (Vietnam) was presented. A total of 55 species and subspecies of testate amoebae belonging to 9 genera and 6 families were identified from 28 samples. Species diversity of testate amoebae of plankton was higher than the bottom samples. The highest frequency of occurrence being of Centropyxis aculeata (64.3%), Netzelia wailesi (39.3%), Difflugia acuminata (32.1%), Arcella discoides scutelliformis (28.6%) and Lesquereusia modesta (28.6%). The most species-rich genera are Difflugia (25), Arcella (12), Centropyxis (5) and Netzelia (4). The species accumulation curve based on the entire dataset was unsaturated and described by the equation y = 12.56N046. The average species richness of testate amoebae per sample in plankton (13.0 ± 3.1) is statistically higher than in the bottom samples (1.8 ± 1.5) (p &lt; 0.001). The result of the redundancy analysis shows that the studied hydrochemical water characteristics (temperature, pH, dissolved oxygen, electrical conductivity and salinity) explained only 31.6% of the variation of testate amoeba diversity, wherein the first and second axes explained 11% and 10.2% of this variation, respectively.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>раковинные амёбы</kwd><kwd>видовое разнообразие</kwd><kwd>река Коко</kwd><kwd>Куангнам</kwd><kwd>Дананг</kwd><kwd>анализ избыточности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Testate amoebae</kwd><kwd>species diversity</kwd><kwd>Coco River</kwd><kwd>Quangnam</kwd><kwd>Danang</kwd><kwd>the redundancy analysis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Автор выражает благодарность к.б.н.
