Calculation of multiple phylogenetic diversity metrics for plant communities using established phylogenetic trees and null model approaches to test for phylogenetic clustering or overdispersion.

Complete census of all individual plants in gridded plots with spatial mapping, tissue sampling, and photosynthetic area measurement for metabolic rate estimation in herbaceous plant communities.

Nested sampling design to construct species-area relationships across multiple spatial scales by subdividing plots into equal-area quadrats and averaging species counts across equivalent areas.

Standardized pellet count method for estimating deer density using systematic transect surveys with random placement. Identifies scat to species level where possible to distinguish herbivore types usi...

Comprehensive measurement of leaf morphological, physiological, and chemical traits including stomatal conductance, leaf mass per area, nitrogen content, and spectral properties to characterize plant ...

Systematic collection and spectrophotometric analysis of flowers across elevation gradients to quantify color variation. Targets pollinator-visible flower regions and converts reflectance to pollinato...

Integration of field GPS coordinates with multiple spatial datasets (elevation, slope, land cover, climate) to characterize environmental conditions at population locations. Uses established spatial d...

Systematic collection and GPS mapping of predator scats along established trail networks to quantify spatial patterns of predator activity relative to human disturbance. Scat density is calculated per...

Pressing and identification of plant voucher specimens using standard botanical keys and herbarium references.

Conversion of reflectance spectra into bee and bird visual spaces using established photoreceptor sensitivity models. Uses color hexagon model for bees and receptor-noise limited model for birds to ca...
