Method synopsis

Uses phylogenetically independent contrasts and concentrated changes tests to examine relationships between species traits while controlling for shared evolutionary history. Employs multiple algorithms to test evolutionary patterns.

Synthesized from method descriptions across 1 paper using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Developing an evolutionary ecology of fear: how life history and natural history traits affect disturbance tolerance in birds (2006), Animal Behaviour. Implementations in other papers (listed below) may differ.

1. Compile species trait data
   Maximum body mass tabulated from Dunning (1993), supplemented with data from other sources when species not reported. Life history and natural history traits primarily taken from species accounts published in The Birds of North America and the Handbook of Australian, New Zealand, and Antarctic Birds. Collected data on diet, clutch size, breeding system, habitat type, habitat density, longevity, and cooperative breeding status.
   Quantities: Data compiled for 150 species across multiple trait categoriesDuration: Literature compilation phaseConditions: Standardized trait definitions used across species
   Equipment: published species accounts, taxonomic references

Typical Equipment

• MacClade 4.03
• SPSS 11
