This stems in latitudinal and altitudinal climate gradients in regolith formation. Climate change is expected to lead to latitudinal and altitudinal temperature increases. The delineation corresponds with the differentation between Montane and Alpine level according to altitudinal zonation. Fauna is similarly distributed, with distinct altitudinal zonation present. Temperate bat species are also altitudinal migrants. The nutrient content of soils at different elevations further complicates the demarcation of altitudinal zones. They also show an adaptation to high altitudes called altitudinal melanism. Some highland species have altitudinal migrations. Today, altitudinal zonation represents a core concept in mountain research. This gives us our modern which is controlled by altitudinal zonation. Vegetation varies considerably due to the large altitudinal range within the park. Not all mountainous environments exhibit sudden changes in altitudinal zones. The vegetation of the islands sub-divides into distinct altitudinal zones. The climate in the Western Ghats varies with altitudinal gradation and distance from the equator. Vertebrate animals often span across altitudinal zones according to the seasons and food availability.
