snow cover duration
Number of days from autumn snow onset to spring snowmelt, providing temperature stabilization and protection for overwintering organisms
growing degree days
Temperature accumulation metric calculated using averaging method with base temperature, used to predict insect phenology and plant development
phylogenetic signal
The tendency for related species to resemble each other more than expected by chance, measured by Blomberg's K and Pagel's lambda
seed viability
The measure of seed quality based on embryonic development and potential for successful germination
synchrony
The degree to which individuals in a population exhibit coordinated timing of nesting activity
Julian day
Day of year from 1-365 used to measure timing of biological events
flowering curve
Graph showing the number of open flowers over time, describing temporal distribution of flower openings with properties like start date, end date, mean date, breadth, and skewness
phenological overlap
The number of weeks during a growing season when both pollinators and their floral resources are active and available
