Monodominance

Monodominance is an ecological condition in which more than 60% of the tree canopy comprises a single species of tree.^[1]^[2] Monodominant forests are quite common under conditions of extra-tropical climate types. Although monodominance is studied across different regions, most research focuses on the many prominent species in tropical forests. Connel and Lowman, originally called it single-dominance.^[3]^[1] Conventional explanations of biodiversity in tropical forests in the decades prior to Connel and Lowman's work either ignored monodominance entirely or predicted that it would not exist.^[4]

Connel and Lowman hypothesized two contrasting mechanisms by which dominance can be attained.^[3] The first is by fast regrowth in unstable habitats with high disturbance rates. The second is through competitive exclusion in stable habitats that have low disturbance rates.^[2]^[3] Explanations of persistent monodominace include the monodominant species being more resistant than others to seasonal flooding, or that the monodominance is simply a sere.^[4] With persistent monodominance, the monodominant species successfully remains so from generation to generation.^[4]^[2]
