Impact/Purpose:
In order to further understand the impact of chemical exposures on wildlife populations, ecological modelers develop tools that can be used to extrapolate from laboratory toxicity studies to real-world applications. The Fish Toxicity Translator is tool that uses size-dependent effects of chemical and non-chemical stressors paired with underlying fish life history models to estimate effects of chemical exposures on populations. This presentation describes both the modeling process and demonstrates usage of the Fish Toxicity Translator model and tool.
Description:
Populations of aquatic organisms are exposed to diverse natural and anthropogenic stressors. Traditional toxicity testing provides endpoints that need to be interpreted and extrapolated in order to understand impacts of exposure on wildlife populations. The Fish Toxicity Translator is a mechanistic population model developed by the USEPA that uses life history characteristics of fish, laboratory derived measures of acute and chronic toxicity, and ecotoxicological theory to estimate population level effects of chemical exposure scenarios. The Fish Toxicity Translator uses a novel modeling approach, size-structured integral projection modeling, that allows for the incorporation of size-dependent acute and chronic effects of chemical and non-chemical stressors. Model development has taken place in the open source R language has been developed into an R package with an accompanying graphical user interface using R Shiny.
