The research on algal communities’ response to altitude and altitude-related climatic conditions is sparse. So far, a full, accessible list of algae from the water bodies of the South-Tajik Depression has not been available. | Turkish Journal of Botany Turk J Bot (2015) 39: 535-546 © TÜBİTAK doi: Research Article Freshwater algal diversity of the South-Tajik Depression in a high-mountainous extreme environment, Tajikistan 1, 2 3 Sophia BARINOVA *, Mariyo BOBOEV , Hikmat HISORIEV 1 Institute of Evolution, University of Haifa, Haifa, Israel 2 Khatlon Scientific Center, Academy of Sciences of the Republic of Tajikistan, Kulob, Tajikistan 3 Institute of Botany, Plant Physiology, and Genetics, Academy of Sciences of the Republic of Tajikistan, Dushanbe, Tajikistan Received: Accepted: Published Online: Printed: Abstract: The research on algal communities’ response to altitude and altitude-related climatic conditions is sparse. So far, a full, accessible list of algae from the water bodies of the South-Tajik Depression has not been available. We compiled an algal species list of 1190 taxa that were revealed by us or listed in references in the South-Tajik Depression high-mountain rivers Kafirnigan, Vakhsh, Kyzylsu, Yakhsu, and Tairsu and in the lakes of its basin. The altitude gradient of the studied area is about 2500 m above sea level. An altitude-related algal diversity analysis was done with help of statistics and bioindication. The Willis curve for the distribution of species to genera had a trend line of R2 = . A multivariate analysis was used for quantitative estimates of the ecological tolerance ranges of critical species and for detecting cardinal factors and trends at local water bodies to global levels of biodiversity evolution. Our analysis shows that species distribution was strongly affected by altitude and altitude-related climatic variables. Statistical methods revealed that temperatures stimulate algal species diversity, while precipitation and altitude suppress it. One of the floristic complexity criteria is the average species richness of the algal genera or .
