Última Combining time trends in multiple metrics for identifying persistent changes in population processes or environmental stressors ArchiMer Trenkel, Verena; Rochet, Marie-joelle. P>1. Metrics have become a standard way for summarizing environmental monitoring results. Different metrics react differently to natural variations and human-induced stressors. We suggest that combined analysis of time trends in selected biological metrics allows identification of biological processes (e.g. individual growth, mortality or recruitment) that have changed (increased or decreased) persistently. Alternatively, time trends in the abundance of sensitive species could indicate changes in environmental stressors. 2. We calculate the joint likelihood of time trends in three metrics and use it to evaluate the evidence in the data for different combinations of metric time trends. A simulation study provides guidelines for interpreting... Tipo: Text Palavras-chave: Generalized additive model; Indicators; Likelihood principle; Quadratic programming; Survey data.
