Overview

Accurate estimates of the diets of predators are required in many areas of ecology, but for many species current methods are imprecise, limited to the last meal, and often biased. The diversity of fatty acids and their patterns in organisms, coupled with the narrow limitations on their biosynthesis, properties of digestion in monogastric animals, and the prevalence of large storage reservoirs of lipid in many predators, led us to propose the use of quantitative fatty acid signature analysis (QFASA) to study predator diets.

This package allows diet estimates to be calculated via QFASA, MUFASA (or MLE QFASA) and by simultaneous estimation of calibration coefficients and diets. It also contains functions to compute confidence intervals, measures of repeatability, pseudo predator generation, etc...
