Specific Leaf Area (SLA)
Comprehensive measurement of vegetative traits including specific leaf area, trichome density, water use efficiency, and percent water content from field-collected leaves using scanning, drying, weigh...
HOBO sensor environmental monitoring
Continuous collection of local weather data at 5-minute intervals throughout growing seasons to capture fine-scale environmental variation affecting disease dynamics.
Mantel test (Plantae)
Meta-analytical approach to synthesize population-level climate sensitivities across multiple species using structured population models and standardized effect sizes. Incorporates life history traits...
Li-Cor 6400 photosynthesis measurement
A novel approach to measure light response curves for entire plant communities rather than individual plants using tent-based gas exchange measurements across multiple light levels. This method contro...
Leaf pack method
Standard litterbag method deployed across elevation gradient to study litter decomposition rates and microbial succession. Involves placing known masses of litter in mesh bags and retrieving over time...
Systematic grid demographic monitoring of aspen
Systematic establishment of gridded plots across watersheds followed by long-term monitoring of tagged individual trees for mortality and recruitment rates. Combined with environmental characterizatio...
Flow cytometry nuclear DNA content analysis (Salicaceae)
Cytotype inference using twelve multinational microsatellites with 97% correct classification for cytotype. Individual plants defined as diploid or triploid based on maximum number of alleles observed...
Multi-factor abiotic site characterization
Comprehensive measurement of soil nutrients, moisture, pH, topographic aspect, and interpolated climate variables to characterize abiotic conditions at vegetation sampling sites.
partial least squares regression (PLSR) (Salicaceae)
PLSR modeling approach using leaf spectral reflectance measurements to extrapolate functional trait values from subset of direct measurements to larger sample sizes. Ten-fold cross-validation used for...
Floral orientation manipulation for fitness measurement (Plantae)
Experimental manipulation of natural floral orientations combined with pollen supplementation to test effects on seed set and female fitness.
Reciprocal transplant germination experiment
Field experiment testing seed germination of different genotypes/treatments in natural microhabitats of related species to assess niche requirements and differentiation.
Maximum likelihood phylogenetic analysis
Maximum likelihood phylogenetic analysis of full genome sequences using MUSCLE alignment and Tamura-Nei evolutionary model to determine relationships between outbreak isolates and assess overwintering...
Seed burial experiments
Seed-burial and greenhouse germination experiments to estimate seed bank-related vital rates including seed germination and stasis.
tree mass measurement
Direct measurement of aboveground biomass on 673 trees across five tropical countries. Compilation of tree mass dataset including 101 trees greater than 100 cm in diameter.
