LUMaR calculator: using bugs to assess stream health

Calculate LUMaR (and other index) scores from macroinvertebrate samples taken in the Melbourne region

Waterway Ecosystem Research Group	urbanstreams.net	Melbourne Waterway Research-Practice Partnership

This page allows you to upload macroinvertebrate data files (collected from the Melbourne region), calculate LUMaR scores from them, and (with planned additions to the tool) explore the taxa driving any trends of interest in the data. (SIGNAL score calculation is also planned)
If you are proficient in R, and want to explore the macroinvertebrate models that underlie LUMaR as well as independently perform the analyses that this page does, then you can install the melbstreambiota package.
To install the package type the following into your R console.
install.packages('https://tools.thewerg.unimelb.edu.au/documents/misc/melbstreambiota_0.1.1.tar.gz', repos = NULL, type = 'source')
Please note that the package is 663 Mb, and can take ~15 min to install once it is downloaded on a powerful computer. (Once it is installed, it is quick to load and use).
Associated resources for using the package:
Manual, which details the usage of all package functions, and contents of all package data;
Vignette, which illustrates the functions of the package with worked examples.

Once uploaded, the provided raw data will be shown here.

Then check the next panel for how the data is manipulated before calculating LUMaR. If you are happy with that go to the final tab to calculate and download LUMaR results.
