A) Location of Nam Co on the Tibetan Plateau, and B) sampling sites according to the habitat type and abundances (living and sub-fossil organism (2 valves = 1 organism) per gram wet weight, org/g wet) of Tonnacypris stewarti (Daday 1908) in Nam Co. Abundance distribution was categorized into three distinct patterns: a complete circle (indicating low abundance), a cross-circle (indicating medium abundance), and a circle with a central line (indicating higher abundance). Sample numbers correspond to Table 2. The elevation bar corresponds to map B.
