Application of ecological models to ecological risk assessment -The extrapolation and the life history sensitivity analysis-

摘要

Ecotoxicological data using life table evaluation are reviewed and analyzed with the power function model. Life table evaluation and population growth experiments are proposed as experimental procedures that provide demographic parameters (e.g. intrinsic rate of natural increase) relevant for calculating extinction risk due to pollutant exposure. Totally 47 concen- tration vs. Intrinsic rate data sets were collected and analyzed with two indices in the power function model, α and β.
