Field Stressor-Response Association Gallery

The Field Stressor-Response Associations Gallery provides examples of stressor-response relationships computed from field data. They illustrate stressor-response relationships that have been observed in several datasets, using some of the methods described in Volume 4: Data Analysis. We recommend that you review the description of the analytical methods prior to viewing or using the graphs.

These plots illustrate the types of relationships that may be found between some common stressors and biological responses. However, it is unlikely that the stressor-response relationships shown here will be exactly applicable to your particular situation. Please review the metadata provided with each graph carefully: examine whether the sampling and analysis methods are comparable, and evaluate whether the response and explanatory variables are relevant to your aquatic system and causal analysis.
