Species richness peaks for intermediate levels of biomass in a fractal succession with quasi-neutral interactions

Article Abstract:

A scaling relationship between various species and total community biomass are used to propose a new self-similar process of biomass partitioning during a community assembly process. The results have illustrated that quasi-neutral interactions among coexisting species lead to the most commonly observed pattern, an envelope where diversity peaks at intermediate values of total biomass.

Predicting root biomass from branching patterns of Douglas-fir root systems

Article Abstract:

Branching networks such as river systems and tree crowns found in nature are said to be self-similar, or following scale-invariant branching rules. The study uses the root systems of the Douglas-fir to establish a relationship between trunk diameter and root mass.

The long-term relationship between plant diversity and total plant biomass depends on the mechanism maintaining diversity

Article Abstract:

The relationship between plant diversity and total plant biomass is discussed. The potential of niche differences among plants promote high total biomass in polyculture is investigated.
