Method synopsis

A method for constructing plant-pollinator interaction networks at multiple temporal scales from temporally-explicit field observations. Networks are aggregated from daily observations to weekly, monthly, yearly and multi-year scales using specific sampling effort thresholds.

Synthesized from method descriptions across 1 paper using this protocol.

Procedure as described in the canonical source

Steps below were extracted from the paper that introduces this protocol — Temporal scale-dependence of plant–pollinator networks (2020), Oikos. Implementations in other papers (listed below) may differ.

1. Standardize temporal data
   Standardized southern hemisphere dates by adding 182 days to each sampling date for each site in the southern hemisphere (n=17) to ensure the whole flowering season takes place within one single calendar year. For each site, all observed interactions within the same temporal unit (day, week, month, year) or the total sampling extent were used to construct quantitative interaction matrices with rows corresponding to plant species, columns to pollinator species, and cell entries to number of floral visits.
   Quantities: 17 southern hemisphere sites standardizedDuration: Applied to entire flowering season within calendar yearConditions: Temporal standardization across hemispheres
   Equipment: Data processing software
2. Aggregate networks at multiple temporal scales
   Aggregated data at five temporal scales: day, week, month, year, and multiple years. Applied specific inclusion criteria - weekly networks required at least 2 sampling days and at least 4 days temporal span covering at least 11 days; monthly networks required at least 8 sampling days covering at least 60 days; yearly networks required at least 8 sampling days covering at least 60 days; multiple-year networks required at least 16 sampling days covering at least 381 days.
   Quantities: 1307 daily, 380 weekly, 229 monthly, 71 yearly, and 19 multiple-year networks constructed from 124,708 total interactionsDuration: Temporal spans from single days to multiple years (up to 4096 days maximum temporal extent)Conditions: Different minimum sampling requirements for each temporal scale
   Equipment: R statistical software
