An examination of spatial data for 24 woody tropical rain forest plants showed either density-dependence or distance-dependence in plant offspring, supporting the hypothesis. However, other causal factors such as allelopathy were also suggested in some cases. [14]
A single hectare of rainforest may contain 42,000 different species of insect, up to 807 trees of 313 species and 1,500 species of higher plants. [5] Tropical rainforests have been called the " world's largest pharmacy ", because over one quarter of natural medicines have been discovered within them.
A tropical plant community on Diego Garcia Rangeland monitoring using Parker 3-step Method, Okanagan Washington 2002. Plant ecology is a subdiscipline of ecology that studies the distribution and abundance of plants, the effects of environmental factors upon the abundance of plants, and the interactions among plants and between plants and other organisms.

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]
It is considered likely that hitting 3.5 °C (6.3 °F) of global warming would trigger the collapse of rainforest to savannah over the course of around a century (50-200) years, although it occur at between 2 °C (3.6 °F) to 6 °C (11 °F) of warming. [79] [80] Forest fires in Indonesia have dramatically increased since 1997 as well. These ...
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. [5] [6] The most representative are the Borneo rainforest, one of the oldest rainforests in the world, the Brazilian and Venezuelan Amazon Rainforest, as well as the eastern Costa ...
The paper's worst-case scenario for both stressors had only 53% of the original rainforest area surviving as a continuous ecosystem by 2050, with the rest reduced to a severely fragmented block. [48] Another study estimated that the rainforest would lose 69% of its plant species under the warming of 4.5 °C (8.1 °F). [49]
About half of the world's tropical rainforests are in the South American countries of Brazil and Peru. Rainforests now cover less than 6% of Earth's land surface. Scientists estimate that more than half of all the world's plant and animal species live in tropical rainforests.
