Tropical Alpine Environments
Plant Form and Function

Plants growing in tropical alpine environments (at altitudes above the closed canopy forest and below the limit of plant life) have evolved distinct forms to cope with a hostile environment characterized by cold, drought and fire. Unlike temperate alpine environments, where there are distinct seasons of favourable and unfavourable conditions for growth, tropical alpine habitats present summer conditions every day and winter conditions every night. Using examples from all over the tropics, this fascinating account reviews, for the first time, the unique form and functional relationships of tropical alpine plants examining both their physiological ecology and population biology. It will appeal to anyone interested in tropical vegetation and plant physiological adaptations to hostile environment, as well as to researchers in biogeography and ecology.
