Abstract EN
This research examines the diversity-productivity relationship in a semiarid scrubland, initially under late successional conditions and subsequently under early successional conditions created by experimental clearing, to explore the roles that productivity and stochastic mortality play in species exclusion in this environment.
A total of fifteen plots were studied by measuring environmental conditions and biomass components of shrubs and seedlings.
These stands were distributed along a productivity gradient across five different landforms.
A hypothesis about the stochastic self-thinning mortality model along the gradient was evaluated with the diversity-productivity-environment data.
The diversity-productivity relationship was linear and reversed between the early and late succession stages.
The hypothesis of stochastic mortality of species exclusion was rejected in the early stages of succession and partially accepted in the mature stage of succession.
Species exclusion was negatively related to productivity gradients, suggesting that strong interspecific competition occurs in high productivity plots and that a larger number of species can survive in higher abiotic stress landscapes.
Further research is needed to understand the temporal and spatial variations of the ecological interactions that shape this plant community.
