Method synopsis

Quantifies temporal overlap in flowering periods between species pairs using Schoener's index, where values approach 1 when flowering curves coincide and approach 0 when they don't overlap.

Synthesized from method descriptions across 2 papers 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 — Flowering phenology in subalpine meadows: does climate variation influence community co-flowering patterns? (2010), Ecology. Implementations in other papers (listed below) may differ.

1. Calculate flowering overlap indices
   Calculate Schoener's index (SI) of niche overlap using SI = 1 - (1/2) Σᵢ |pᵢₖ - pⱼₖ|, where pᵢₖ is the proportion of flowering by species i occurring on day k, with values close to 0 when flowering curves don't overlap and approaching 1 when they coincide perfectly
   Quantities: Calculated for each plot separately, then averaged across all plots for each yearDuration: Annual calculations for species pairsConditions: Missing data points filled by linear interpolation for days without data
