Abstract
The genotypic and phenotypic processes were incorporated into one system
in the gene-individual-population relationships under the framework of
Individual based models (IBMs). The gene types addressing different
degrees of metabolic efficiency and toxin susceptibility were provided
as attributes in the individuals. Subsequently ecological processes such
as food competition and movement were allowed concurrently on the 2-D
space to determine the suitable species adapted to the system. The
integrative gene-individual-population model accordingly responded to
gene exchanges between the neighboring individuals through conjugation.
At a substantially low level of gene exchange, system heterogeneity
increased to produce high levels of eco-exergy, being presented by
species diversity and total population size in the system. The issues
related to genetic and ecological effects in the integrative
gene-individual-population relationships were further discussed. (C)
