Some of the Mechanisms for Coexistence of Tree Species Diversity in Tropical Forests: A Review of Effects of Tree Density Dependence

Tree communities contribute to maintenance of species diversity in tropical forests. Coexistence many tree is not without competition. Therefore, coexistence and size diversities occur sequentially or simultaneously natural Understanding competition mechanisms requires knowledge interactions within between species. However, conservation efforts strategies failed due inability identify maintain functional among the forest. Also, most trees died because pressure on their habitats limiting growth resources. Hence, identity, minimum distance neighbouring which are responsible for competing forests have been explicitly reviewed. this review evaluated some density dependent alpha Many interactive Inter- intra-specific competitions significant both facilitate positive negative dependence. switching from dependence may situations. Positive effects regulate abundance through conspecific heterospecific structures. Aggregates neighbours constitute forest spatial structure. Negative mutually exclusive basically ranged effect identity neighbours, reference community Some shorten distances than interactions. Conspecific structures improved survival rare Interactive population inequality, respectively.
