More complex environmental history trajectories could feasibly unravel more memory effects.
The natural spatial and temporal heterogeneity in salinity, alkalinity, pH, and pCO2 in estuaries impose more complex environmental stresses on calcifying biota than in the open ocean where the environment is far less variable.
These changes could have important effects on terrestrial ecosystems since alteration in fire activity may occur quite rapidly, generating ever more complex environmental challenges for species dispersing and adjusting to new climate conditions.
The CA model is, therefore, currently of limited value in predicting the estrogenic effects of more complex environmental mixtures.
This greater number of detected QTL also may be the result of the more complex environmental conditions found in the field relative to the controlled environment.
The role of more complex environmental factors (usually psychosocial in nature) in mediating and modifying psychopathology of children is investigated much broader [ 5], but still highly debated.
More complex environmental mixtures have been evaluated for mutagenic activity at the hisD3052 allele of Salmonella, primarily in strain TA98, than in any other target or mutation assay.
A second area where advances in general theory will help is in expanding our understanding of adaptation to accommodate more complex environmental change, such as constantly changing environments or scenarios where several aspects of the environment change simultaneously.
More complex environmental parameters such as the elevation of vineyards have also been considered, and stilbenes tend to accumulate at higher elevations, albeit in a cultivar-dependent manner [ 46].
By using minimally-parameterized models that better capture fundamental tumor compositions and kinetics, one may, as here, uncover properties intrinsic to tumor cells that have already been attributed by other models to more complex environmental factors.
