“…Algae type Bacillariophyta has a high tolerance and adaptation to environmental changes [23]. Bacillariophyta are commonly found in sediments, rocky substrates, and plants [24]. This is in line with the behavior of B. binotatus, which likes to be fast-flowing and dwells between rocks [25].…”

B.binotatus is native fish from Ciliwung River whose existence is decreasing due to the similarity of food sources between native species and introduced species, causing competition to seek food. The study aimed to determine the trophic level and position B. binotatus in the Cilliwung River ecosystem based on gut content analysis using the purposive sampling method during August-October 2021. Data were obtained from a total of 60 samples from the Ciesek River, Cirangrang, and Sukabirus. The fishes were dissected, and gut contents were observed using a light microscope, with observations repeated 3 times for each sample. Data analysis includes the relative length of gut, index of preponderance, nichce area, niche overlap, and trophic level of an organism. The feed source consists of Bacillarophyta (68.62%), Chlorophyta (16.40%), Manogononta (8.41%), Cyanophyta (2.81%), Euglenaphyta (1.70%), Amoebozoa (1.01%), Copepods (0.93%), and detritus (0.11%). The result showed that B. binotatus in Ciliwung River is at trophic level II and included as an omnivore (2.1 < Troph < 2.9). B. binotatus is as an omnivore and have a common food source with introduced species, causing competition to seek food.

В фитопланктоне водоемов и водотоков Крайнего Севера Западной Сибири (п-ва Гыданский, Ямал, Тазовский) с использованием сканирующей электронной микроскопии обнаружены 7 представителей рода Fallacia и недавно описанного рода Pseudofallacia Y. Liu, J.P. Kociolek et Q.X. Wang, в т. ч. новый для науки вид Pseudofallacia makarovae Genkal & Yarushina sp. nov. У Fallacia pygmaea Kütz., F. forcipata Grev., F. subhamulata (Grev.) D.G. Mann и Pseudofallacia tenera (Hustedt) Liu, Kociolek et Wang. диапазоны изменчивости длины и ширины створки, числа штрихов в 10 мкм совпадают с литературными данными, за исключением Fallacia insociabilis (Krasske) D.G. Mann и Pseudofallacia losevae (Lange-Bertalot, Genkal et Velhov) Liu, Kociolek et Wang. Новый для науки вид P. makarovae имеет большое сходство с P. losevae и Fallacia muraloides (Hust.) D.G. Mann, однако отличается от последних размерами центрального поля, доходящего до края створки. Полученные данные об экологии и распространении исследованных видов расширяют наши представления о них. К л ю ч е в ы е с л о в а : Крайний Север Западной Сибири, Bacillariophyta, морфология, электронная микроскопия, Fallacia, Pseudofallacia Введение Род Fallacia описан в 1990 г. (Round et al., 1990). К характерному признаку рода относится разделение штрихов продольными стернумами, расположенными ниже уровня поверхности створки и (при наблюдении в световом микроскопе) образующими гиалиновую «лиру». В этот род переведены Navicula pygmaea Kütz. и N. forcipata Grev.
