TL;DR
These simulations show that the evolutionary component of Echo makes a significant contribution to its behavior and that Echo shows good qualitative agreement with naturally occurring species abundance distributions and species-area scaling relations.
Abstract
Echo is a generic ecosystem model in which evolving agents are situated in a resource-limited environment. The Echo model is described, and the behavior of Echo is evaluated on two well-studied measures of ecological diversity: relative species abundance and the species-area scaling relation. In simulation experiments, these measures are used to compare the behavior of Echo with that of a neutral model, in which selection on agent genotypes is random. These simulations show that the evolutionary component of Echo makes a significant contribution to its behavior and that Echo shows good qualitative agreement with naturally occurring species abundance distributions and species-area scaling relations.

Not only is the distribution lognormal, but the constants or parameters seem to be restricted in a peculiar way, and they are not fixed, but they are interlocked.

It is shown that the limiting reaction-diffusion equations associated with particle systems can have different qualitative behavior from those obtained by simply adding diffusion terms to mean field equations.

It is argued that multisite recognition is a more reliable method of distinguishing between molecules than single site recognition, which may have been an important evolutionary consideration in the selection of weak non-covalent interactions as the basis of antigen-antibody bonds.

The role of resource quality and in particular spatial environmental heterogeneity in the distribution of these resources on the evolution of virulence is examined to underline the importance of considering spatial structure in order to understand evolutionary processes.

574 Citations1980George Sugihara
The model presented offers explanations of two ubiquitous patterns in nature: the canonical lognormal and the resulting species-area constant and an interesting invariance in the pattern of apportionment is observed for assemblages with three species.

The development of theoretical community ecology over the last two decades is examined in an attempt to determine why some avenues of investigation have proven disappointing, whereas others, such as the theory of island biogeography, have enjoyed at least modest success.

This paper reviews the basic mathematical literature and three influential examples from the ecological literature are considered and placed within the general framework, which is shown to be a powerful one for the study of spatial ecological interactions.

A drop in sea level and climatic change are most frequently invoked to explain mass extinctions, but new theories of collisions with extraterrestrial bodies are gaining favor.

A simple amplification model is introduced to characterize the transition from a log-normal distribution to an inverse-power Pareto tail.

This paper reviews the four examples listed above and maps them into a common mathematical framework, discussing their similarities and differences, and suggests new applications of connectionist models, and poses some problems to be addressed in an eventual theory of connectionism.

154 Citations1993Thomas B. Kepler, Alan S. Perelson
The results show that the optimum mutation schedule is one with brief bursts of high mutation rates interspersed between periods of mutation-free growth, and this model provides a framework within which the anatomy and kinetics of the germinal center reaction can be understood.

143 Citations1986Stephen W. Pacala
Models developed for the dynamics of multi-species communities of annual plants that lack seed dormancy demonstrate that dispersal may markedly influence the outcome of competition among plant species, even in a physically homogeneous environment, due to an effect of dispersal on the spatial distribution of individuals.

Some reported counts of species abundances, when tallied by octaves or other appropriate intervals, do not conform at all well to the expected normal (lognormal) distribution, but the departures therefrom seem to be by no means systematic or consistent.
