These all share a common "strangling" growth habit that is found in many tropical forest species. [1] [failed verification] This growth habit is an adaptation for growing in dark forests where the competition for light is intense. These plants are hemiepiphytes, spending the first part of their life without rooting into the ground. Their seeds ...
Amazon River rain forest in Peru. Tropical rainforests are hot and wet. Mean monthly temperatures exceed 18 °C (64 °F) during all months of the year. [4] Average annual rainfall is no less than 1,680 mm (66 in) and can exceed 10 m (390 in) although it typically lies between 1,750 mm (69 in) and 3,000 mm (120 in). [5]
They have particular adaptations to take in extra oxygen and remove salt, allowing them to tolerate conditions that kill most plants. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse due to convergent evolution in several plant families.
Heliconia is a genus of flowering plants in the monotypic family Heliconiaceae. Most of the 194 known species [3] are native to the tropical Americas, but a few are indigenous to certain islands of the western Pacific and Maluku in Indonesia. [2] Many species of Heliconia are found in the tropical forests of these regions.
Tropical rainforests have been called the "jewels of the Earth" and the "world's largest pharmacy", because over one quarter of natural medicines have been discovered there. [2] Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere. [3]
Mangrove plants require a number of physiological adaptations to overcome the problems of low environmental oxygen levels, high salinity, and frequent tidal flooding.Each species has its own solutions to these problems; this may be the primary reason why, on some shorelines, mangrove tree species show distinct zonation.
Idiospermum is a monotypic genus (that is, a genus that contains only one species) in the family Calycanthaceae.The sole included species is Idiospermum australiense − commonly known as idiotfruit, ribbonwood, or dinosaur tree − which is found only in two small areas of the tropical rainforests of northeastern Queensland, Australia.
Tropical rainforest ecosystems include significant areas of biodiversity, often coupled with high species endemism. [6] Rainforests are home to half of all the living animal and plant species on the planet and roughly two-thirds of all flowering plants can be found in rainforests.
