Analysis Tools

Building a Quantitative Food Web

In order to calculate estimates of energetic carrying capacity in different lotic habitats,  flow webs, quantifying trophic energy routing must be constructed. This level of analysis is often complex, tedious and extremely time consuming. By developing  a series of R analysis tools  I hope to streamline and simplify this process, allowing managers to utilize these methods to diagnose energetic limitations prior to prescribing treatments. R scripts are designed and constructed to be used at multiple analysis levels, depending on questions and data resolution (abundance, biomass or estimates of annual productivity).
