The growth and subsequent success of the plant is dependent on its ability to extract resources. The supply of resources may be unlimited or more commonly limited in most environments. A species resource needs, habitat requirements and environmental tolerances. The concept of space as an integrative resource used by individual plants, allows us to study the interaction among plants as a function of proximity of neighbor plants rather than the interaction through resource pools. D. Relative emergence time influences the growth and success of individual plants in populations.
Larger plants have greater access to shared resources, therefore they get bigger faster.
They are initially larger because they emerged first. E. Additional factors that influence inter-specific interference or the inherent ability of a species to use resources over another species. Density - Additive affects 2. DeWit's models Qualitative Assessment of the interaction between 2 species. This study design removes the confounding effect of total density change that one gets in an additive design interference experiment.
