Description

Metrics for assessing ecological indicators of biodiversity in rivers and lakes. Specifically coded to be used with TIBCO Enterprise Runtime for R (TERR).

This package contains several functions which compute multiple ecological metrics at different Taxonomic Levels (TL) using multiple season combinations.

• SPEAR (CalcSPEAR)
  Species at Risk

• PSI (CalcPSI)
  Proportion of Sediment-sensitive Invertebrates

• LIFE (CalcLIFE)
  Lotic Invertebrate Index for Flow Evaluation

• Riverfly's ASI (CalcASI)
  Riverfly Angler's Score Index

• Climate Change (CalcCC)
  Climate Change. Thermal indicator.

• DARLEQ (CalcDARLEQ)
  Diatoms for Assessing River and Lake Ecological Quality

Taxonomic Levels are the different output options developed by RIVAPCS to produce results at both species and family levels:
TL1 - BMWP families
TL2 - Revised BMWP (WHPT) families
TL3 - All families
TL4 - RIVPACS species
TL5 - WFD species

Season codes define different season combinations used to calculate the indices, those are listed below:
1 = spring
2 = summer
3 = autumn
4 = spring + summer
5 = spring + autumn
6 = summer + autumn
7 = spring + summer + autumn

There is also a common routine (StandardiseRawTaxa) which should be run prior to any calculation in order to standardise taxa counts into the required Taxonomic Levels.
