Seasonal Algal Diversity and Environmental Parameters of Streams of Samur-Yalama National Park, Azerbaijan

Yusif Abiyev, Shakar Mukhtarova, Aytaj Muradova, Lada Markova, Gulnara Hasanova

This study provides the first comprehensive assessment of freshwater algal diversity and ecological status in the streams of Samur-Yalama National Park, Azerbaijan—a region of high biodiversity but limited baseline data. Seasonal surveys in 2023 recorded 46 algal taxa, including 37 first regional records, across ten rivers spanning contrasting hydrochemical environments. Heterokontophyta dominated (69.6% of taxa), with epilithic and benthic habitats supporting the highest diversity. Simpson’s Dominance Index (0.120–0.131) and saprobic index (0.69–0.89) indicated high diversity and predominantly oligosaprobic to β-mesosaprobic conditions, reflecting mostly unpolluted, welloxygenated waters. Principal Component Analysis identified mineralization (sulfate, calcium, TDS) and nutrient gradients as key drivers of algal community structure. Sensitive diatoms such as Fragilaria capucina and Achnanthidium minutissimum dominated pristine sites, while tolerant taxa like Gomphonema parvulum and Nitzschia palea increased under moderate enrichment. These findings establish a regional reference for algal-based biomonitoring, highlight the vulnerability of semi-arid stream ecosystems to environmental change, and provide essential baseline data for conservation planning, future monitoring, and ecosystem management in the South Caucasus and comparable dryland regions.
