Algal diversity and its relationship with seasonal variation of water quality in Gajedi Lake, Rupandehi District (Nepal)
The current study focuses on the algal diversity of Gajedi Lake in different seasons in connection to the lake's water quality indicators. Algae and water samples were collected from eight peripheral sites of the lake in summer, rainy, and winter seasons in 2021. The water temperature, conducti...

Algae and water samples were collected from eight peripheral sites of the lake in summer, rainy, and winter seasons in 2021. The water temperature, conductivity, total dissolved solids, hardness, alkalinity, phosphorus, free CO2, and dissolved oxygen were recorded as high during the summer season while water pH was high during the rainy season. Altogether 93 species of algae were reported under 52 genera, 30 families, 7 classes and 6 phyla in this study. The largest phylum was Bacillariophyta (44.08%) followed by Chlorophyta (17.20%), Euglenozoa (10.97%), Cyanobacteria (12.90%), Charophyta (10.75%) and Miozoa (1.07%). The Shannon-Weiner diversity index indicated high abundance during the summer season, with more evenly distributed algal species. More algal species were recorded in the winter season. Trachelomonas, Navicula, and Nitzschia were dominant genera during summer; Anagostidinema, Desmodesmus, and Pinnularia were dominant during rainy; and Trachelomonas, Tetradesmus, and Gomphonema were dominant during winter. The redundancy analysis ordination showed that the algal composition varied along with the seasonal changes in physico-chemical parameters. Temperature, pH, and conductivity were thus identified as significant factors influencing species richness. Досліджено різноманітність водоростей оз. Гаджеді (район Рупандехі, Непал) в різні сезони в залежності від показників якості води. Альгологічні проби та зразки води відбирали з восьми периферійних ділянок озера в літній, дощовий і зимовий сезони 2021 р. Температура води, її електропровідність, загальна кількість розчинених твердих речовин, жорсткість, лужність, вміст фосфору, вільного CO2 і розчиненого кисню мали високі показники протягом літнього сезону, тоді як значення pH води були високими під час сезону дощів. У результаті дослідження виявлено 93 види водоростей з 52 родів 30 родин 7 класів і 6 відділів. Найрізноманітніше були представлені Bacillariophyta (44,08%), менш різноманітно — Chlorophyta (17,20%), Cyanobacteria (12,90%), Euglenozoa (10,97%), Charophyta (10,75%) та Miozoa (1,07%). Індекс різноманітності Шеннона-Вайнера показав високі значення протягом літнього сезону з більш рівномірним розподілом видів водоростей. Найбільше видів зареєстровано в зимовий сезон. Влітку домінували Trachelomonas, Navicula та Nitzschia, під час сезону дощів Anagostidinema, Desmodesmus і Pinnularia, взимку — Trachelomonas, Tetradesmus і Gomphonema. Упорядкування аналізу надлишковості показало, що склад водоростей змінювався разом із сезонними змінами фізико-хімічних параметрів. Таким чином, температура, pH і провідність були визначені як важливі фактори, що впливають на багатство видів. M.G.
