Occurrence, Abundance and Distribution of Bleak, Common Spirlin, and Sunbleak in the Environmental Gradients of Small Rivers (Tatarstan)

The probability of occurrence, distribution, and abundance of bleak, common spirlin, and sunbleak in 316 small rivers of the Republic of Tatarstan were studied. The studied region has a high geographical and environmental heterogeneity. The impact of environmental factors on species occurrence was a...
