Method synopsis

Analysis of spatial patterns in ecological data using geostatistical techniques to quantify spatial heterogeneity through nugget-to-sill ratios and autocorrelation ranges. This approach reveals patch structure and spatial dependence in species interactions.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Variation in nectar robbing over time, space, and species (2002), Oecologia. Implementations in other papers (listed below) may differ.

1. Conduct geostatistical analysis of spatial patterns
   Map plants to nearest 10 cm and calculate weekly robbing levels per site for each year of study. Calculate two spatial heterogeneity statistics: (1) nugget-to-sill (N:S) ratio measuring degree of patterning in robbing levels, and (2) range (Ax) measuring distance over which robbing levels were autocorrelated (patch size).
   Quantities: Mapped I. aggregata plants with 10 cm precision across 6 sites in 1998 and 1999Duration: Mapping conducted once per site per year, with weekly robbing measurementsConditions: Field mapping during optimal weather conditions for precision
   Equipment: measuring tapes, mapping equipment, GS+ software (version 5.1.1)

Typical Equipment

• measuring tapes
• mapping equipment
