Method synopsis

Tagged individual plants are monitored twice weekly throughout the growing season to record bloom start dates, bloom end dates, and total flower production. This provides individual-level phenological data relative to population timing.

Synthesized from method descriptions across 54 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 — Herbivory and water availability interact to shape the adaptive landscape in the perennial forb, Boechera stricta (2025), Evolution. The protocol was originally introduced by Emergence of a mid-season period of low floral resources in a montane meadow ecosystem associated with climate change (2011), Journal of Ecology. Implementations in other papers (listed below) may differ.

1. Measure reproductive phenology and fitness
   Visited each plant 2-3 times a week to record number of flowers and fruits, length of longest fruit, and height of bolts. For plants that flowered between censuses, determined day of first flowering from fruit elongation rate. Calculated duration of flowering by subtracting first day of flowering from day when plant ceased flowering. Measured height of tallest bolt at flowering. Calculated probability of producing mature fruits and total length of mature fruits as fitness components.
   Quantities: 2-3 visits per week, height of tallest bolt measured, duration calculated from first to last flowering dayDuration: 2-3 times per week throughout flowering season 2021-2023Conditions: During flowering season across all years
   Equipment: measuring devices for plant height and fruit length
