Method synopsis

Quantified natural selection on floral traits by measuring relationships between trait values, pollinator visitation rates, and reproductive success. Calculated standardized selection differentials to compare selection strength.

Synthesized from method descriptions across 9 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 — Natural selection on floral volatiles and other traits can change with snowmelt timing and summer precipitation (2025), New Phytologist. Implementations in other papers (listed below) may differ.

1. Assess female fitness measures
   Assess four fitness measures: (1) total seeds produced by plant, (2) proportion of fruits escaping seed predation calculated as 1 minus proportion attacked, (3) seeds initiated per flower calculated from average nonaborted fruits, (4) fly oviposition by counting eggs on flowers and elongated buds weekly, then summing across season and dividing by total number of open flowers and buds.
   Quantities: Measurements from flowering plants across all treatmentsDuration: Assessed throughout and after flowering seasonConditions: Field assessments during fruiting period
   Equipment: collection tools for fruits and seeds, magnification for egg counting

Typical Equipment

• digital caliper
• collection containers

Output Measurements

• standardized selection differential
