"In context of Airfield there are a variety of possible alternative images that could be utilised such a cow, a goat, a sheep, a flower or any indeed other type of plant as Airfield operates a nursery.
We utilised such a forest model to study the carbon balance of a tropical montane forest in South Ecuador, comparing two topographical slope positions (ravines and lower slopes vs upper slopes and ridges).
Utilising such a technological setup was shown to be highly effective for sequencing compact microbial genomes, which contain only very low amounts of repetitive DNA [ 5].
The reflux-loop is able to satisfy both long-distance communication and robust positional information: by utilising such a fast molecule as auxin, issues regarding long-distance transport and communication can be solved; by dynamically maintaining high fluxes, different time-scales can be accounted for simultaneously; and through lateral fluxes, robust, steep gradients can be formed.
However, the majority of complex biological traits provide numerous challenges in utilising such an approach, including missing phenotypic data, incomplete phylogenetic information and in the case of convergent evolution, variable ancestral states.
Nevertheless, there has been one very recent report utilising such an operant delay-discounting procedure (Pietras, Cherek, Lane, Tcheremissine, & Steinberg, 2003) based on the adjusting amount task designed for use with rats (see below for details).
Here we consider the possible advantages to the normal epithelial cell of utilising such an external growth factor circuit and suggest that autocrine growth factor secretion, when viewed in a multicellular context, could paradoxically form part of a mechanism for preventing tumour development.
Once developed, it is intended to utilise such models in a diagnostic design capacity, to assist in the formulation of strategies to improve the performance of new and existing urban drainage systems under different climate change scenarios.
