Method synopsis

Beetles were captured using speed nets, marked with tungsten needle dot codes on elytra, and released for recapture monitoring to estimate population sizes and dispersal patterns. Elytral condition was used to determine age classes and emergence timing.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Predicting the contribution of single trait evolution to rescuing a plant population from demographic impacts of climate change (2025), Evolution Letters. The protocol was originally introduced by Early snowmelt projected to cause population decline in a subalpine plant (2019), PNAS. Implementations in other papers (listed below) may differ.

1. Establish study sites and plant populations
   Established study populations at four sites: three 'Poverty Gulch' sites in Gunnison National Forest and one 'Vera Falls' site at Rocky Mountain Biological Laboratory (RMBL), all in Gunnison County, CO. Sites contained both I. aggregata and I. tenuituba plants, with natural hybrid zones between the species at some locations.
   Quantities: Four total sites with typically 30-70 flowering individuals per site per yearDuration: Ongoing since at least 2007 for some measurementsConditions: Subalpine sites in Colorado Rocky Mountains
   Equipment: metal tags for plant identification
2. Fitness assessment through survival monitoring
   Tracked survival to flowering for all plants in common gardens. Plants emerge as seedlings, spend 2-12+ years as rosettes before sending up flowering stalks, then die. Fitness was estimated as binary survival to flowering by end of study in 2019, when all 4512 originally planted individuals had either flowered or died.
   Quantities: 4512 total plants monitored from initial planting through 2019Duration: Multi-year tracking from seedling to reproductive maturity (2-12+ years per individual)Conditions: Natural field conditions in common gardens
   Equipment: metal identification tags
