Pattern-Oriented Modeling of Agent-Based Complex Systems: Lessons from Ecology
This paper argues that recent advances in ecological modeling have come together in a general strategy that provides a unifying framework for decoding the internal organization of agent-based complex systems and may lead toward unifying algorithmic theories of the relation between adaptive behavior and system complexity.
Allocation, plasticity and allometry in plants
The authors need a new way to classify, describe and analyze plant allocation and plasticity because the concepts ‘trait’ and ‘plasticity’ are too broad.
Mechanisms determining the degree of size asymmetry in competition among plants
It is argued that an allometric perspective on growth, allocation, resource uptake, and resource utilization can help to understand and quantify the mechanisms through which plants compete.

The meaning and measurement of size hierarchies in plant populations
It is suggested that size hierarchy is equivalent to size inequality and methods developed by economists to evaluate inequalities in wealth and income, the Lorenz curve and Gini Coefficient, provide a useful quantification of inequality and allow us to compare populations.
Are invasive plant species better competitors than native plant species? - evidence from pair-wise experiments
It is suggested that the influence of an invading species on total plant community biomass is an important clue in understanding the role of competition in a plant invasion.

Describing inequality in plant size or fecundity
A second and complementary statistic is proposed, the Lorenz asymmetry coefficient, which characterizes an important aspect of the shape of a Lorenz curve, which tells us which size classes contribute most to the population's total inequality.
The effect of nutrient availability on biomass allocation patterns in 27 species of herbaceous plants
In most of the species that changed allocation in response to the nutrient treatment, these changes were largely a consequence of plant size, indicating that natural selection has resulted in allometric strategies rather than plastic responses to nutrients.
The allometry of reproduction within plant populations
This work takes an allometric perspective and review existing data on the relationship between individual vegetative and reproductive biomass within plant populations, rather than analysing biomass ratios such as reproductive effort.
