Method synopsis

Statistical method to determine phenological onset and end dates using linear interpolation between census dates to estimate when 10% and 90% of samples were counted for both syrphids and flowering plants.

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 — Maintenance of temporal synchrony between syrphid flies and floral resources despite differential phenological responses to climate (2013), Global Change Biology. Implementations in other papers (listed below) may differ.

1. Calculate phenological response variables using linear interpolation
   Linear interpolation was used to determine the day of year when 10% and 90% of the flower and syrphid community were counted. This provides a day of year value in each year for the onset (10%) and end (90%) of the activity period of the flower and syrphid communities. The same procedure was followed to quantify the end of the activity period for each taxon.
   Quantities: 10% and 90% thresholds for onset and end determinationDuration: Applied to each year of data collectionConditions: Standardized calculation across all years and species

Output Measurements

• onset day of year
• end day of year
• activity period duration
