Geomorphological research in the Fann Mountains of the Pamir-Alay has indicated that subnival processes are occurring. Contemporary subnival sediments indicate that complex relationships occur between the snow patches, subnival waters, and ground. Underneath a semi-permanent snow patch, snow melts slowly from the direction of the ground, resulting in a hollow that is filled with sediments produced by wash-down from the river terraces. The energy of subnival waters washes away and displaces sediments present underneath the snow patch, but also causes them to be redeposited. The sediment features imply a significant impact of the relief under the snow patch on the thickness of nival deposits and the nivation mechanism. The sediments also indicate that subnival waters may be under hydrostatic pressure, which has a considerable impact on both the snowmelt and sedimentation processes.

New data on the phylogeny of four rare and endemic species of Ranunculus L. sect. Ranunculastrum DC. of western Pamir-Alai, one of which is new to science, have been obtained. Ranunculus tojibaevii sp. nov., from the Baysuntau Mountains, Western Hissar Range of Uzbekistan, is described. The new species is closely related to R. botschantzevii Ovcz., R. convexiusculus Kovalevsk. and R. alpigenus Kom., but differs in the blade of the radical leaves, which is rounded-reniform, segments 3–5-dissected, each 2–5-partite with elongated, rounded apical lobes. A phylogenetic analysis, using both the nuclear ribosomal internal transcribed spacer (ITS) and cpDNA (matK, rbcL, trnL-trnF), was informative in placing R. tojibaevii in context with its most closely-related species. Discussion on the geographic distribution, updated identification key, a detailed description, insights about its habitat and illustrations are provided.
