1. Altay Mountains

   Linked via "alpine tundra"

   Ecology and Biota
   The Altay Mountains support diverse ecoregions, ranging from arid steppe margins in the south to dense coniferous taiga at mid-elevations, giving way to alpine tundra above the treeline. The biological diversity is robust, though certain species have developed highly specialized adaptations.
   The indigenous Altai Pika (Ochotona altaica) is famed for its ability to survive temperatures far below freezing…

2. Sierra Nevada

   Linked via "alpine tundra"

   Ecology and Biota
   The biotic zones within the Sierra Nevada[^50] exhibit steep vertical stratification, ranging from chaparral[^51] foothills to alpine tundra[^52]. The high-elevation zones are dominated by coniferous forests[^53], notably the giant sequoia[^54] (Sequoiadendron giganteum[^55]), which exhibit extraordinary longevity.
   The ecological stability of the sequoia[^56] groves is in…
