Document Summary
Species range are constrained by environments condition climate and soil. Terrestrial plants are found to almost all extremes (-418m to +6150m) Lowest spot at dead sea arid and hot with little precipitation but enough to support native species. Also has agriculture and invasive exotic species as a result of human influence in the region. Adapted to dry conditions: closer the sea- plants are more adapted to the saline. Highest end at himalayas, particularly ladakh region landscape is barren and cold. Rollin, not steep has positive influence on growth: plants: longer lived perineal plants. They have low surface area for their leaves and are able to complete their yearly phonological life cycles over a short period of time. Adapted to short growing season, cold climate and do everything within the growing season. Abiotic conditions vary in predictable manner across geographic gradients geographic template: shaped by number of things: response of biota to the environment (adaptation, dispersal, evolution or extinction);
