“…With the amplified impact of anthropogenic activities, various naturally occurring ecological niches have been destroyed (Lu et al, 2022). The deterioration of water quality and its impact on deterioration in the river Ganga ecology is noteworthy (Das et al, 2022). The reason for degradation in the riverine water quality is multiple environmental stressors (Rashid & Romshoo, 2013).…”

In order to explore the characteristics of the periphytic algae community structure and its relationship with environmental factors in the Taiyuan region of the Fenhe River, a total of six sampling sites were investigated in July and December 2021. The effects of water quality status and environmental factors at each sampling point on the community structure of epiphytes were detected. The results showed that a total of 7 phyla and 54 genera of periphytic algae were identified in the Taiyuan region of the Fenhe River, and the species composition was mainly Bacillariophyta, Cyanophyta, and Chlorophyta. According to the analysis results of the biodiversity index, the water body of the Taiyuan region of the Fenhe River is in a state of moderate pollution. The correlation analysis between the epiphytic algae and environmental factors showed that the cell density of algae was significantly correlated with dissolved oxygen (DO), phosphate (PO3− 4-P), chemical oxygen demand (COD), total phosphorus (TP), and transparency (SD) in the wet season. The algal cell density in the dry season was significantly correlated with water temperature (WT), TP, PO3− 4-P, and COD. According to the redundancy analysis, the community distribution of the epiphytic algae in the Taiyuan region of the Fenhe River was closely related to physical and chemical factors such as COD, nitrate nitrogen (NO− 3-N), WT, dissolved organic carbon (DOC), total nitrogen (TN), and TP, and COD is the main environmental factor driving the change in the community distribution of the periphytic algae in the wet season. TN is the main control factor driving the change in the biological community distribution of periphytic algae in the dry season.

“…Chapman (2013) discussed the importance of algae from the ancient times to the future prospect of algae, highlighting their present use and their importance for our Ecosystem like its photosynthetic abilities, as source of pharmaceutical and nutritional human and animal food, bio-fertilizer, industrial uses etc. Das et al (2002) stated that algae can be used as indicator of environmental change and ecosystem's health due to their many attributes like their ubiquitous distributions, their sensitivity to wide range of pollutants and their short life cycle. Nagaland, a northeastern state situated in the Indo Burma Biodiversity hotspot of India has rich biodiversity including algae which are understudied.…”

The present study was carried out at DzuÌkou valley, a high altitude region of Nagaland, Northeast India.Algal diversity was evaluated from 3 depression springs and 2 rivers. A total of 62 algal taxa belonging to41 genera and 8 classes were recorded. The class Baccillariophyceae (37 species) was the most dominantwhile the genus Eunotia (8 species) represented the maximum genera. Biodiversity indices such as ShannonâWiener index (H2), Simpsonâs diversity index (D) and Margalef richness (R) shows maximum diversityand richness in Depression Spring 2 followed by Depression Spring 1, Depression Spring 3, River 1 andRiver 2. Pielouâs index (J) depicted the highest evenness value from River 1. Palmerâs pollutionindex of allthe sites was found to be dâ10 thus indicating no organic pollution. This study will provide a preliminaryscreening for algal community thriving at high altitude of Nagaland and coherently aids to the biodiversityrichness of the Indo-Burma hotspot.
