Starch gel electrophoresis (Polemoniaceae)
Standard enzyme electrophoresis technique used to determine genotypes at the 6PGD-2 locus for parentage assignment. Distinguishes between homozygous medium (MM) and homozygous slow (SS) allelic varian...
Microsatellite genotyping (Polemoniaceae)
PCR amplification of microsatellite loci followed by capillary electrophoresis for allele sizing and polymorphism assessment.
Null model permutation testing
Generation of null models that maintain interaction totals per species while randomizing interaction patterns, followed by permutation tests to assess significance of observed network metrics relative...
Hybrid zone cline analysis over elevational gradient (Polemoniaceae)
Long-term monitoring of plant morphological traits across permanent transects spanning a hybrid zone between two Ipomopsis species along an elevational gradient, with cline fitting to quantify trait g...
Ordinal rust infection severity assessment
Weekly assessment of fungal rust infection using a 6-class ordinal scale from absent (0) to 75-100% infected (5), with infection location recorded.
Transect-based seed sampling for plant population genetics (Ranunculaceae)
Systematic collection of seeds from plants along established transects for genetic analysis. Seeds collected within defined distances of sampling points and pooled by maternal plant.
negative binomial regression
Statistical analysis using zero-inflated negative binomial generalized linear mixed models to account for excess zeros in ecological count data, specifically pollen grain counts.
reflectance-based chlorophyll index (Polemoniaceae)
Non-destructive estimation of leaf chlorophyll concentration using reflectance spectroscopy and vegetation indices.
Evolutionary rescue modeling with environmental stochasticity
Development of deterministic and stochastic population models incorporating empirical estimates of selection, heritability, and phenotypic plasticity to project population persistence under climate ch...
Split-plot experimental design
Replicated split-plot design with snowmelt manipulated at plot level and precipitation manipulated at subplot level.
