ascent: Multi-Layer Decomposition of Functional Community Restructuring
Implements the 'ASC-CFD' (Assemblage Shift Characterization -
Community Functional Dynamics) framework for decomposing functional community
restructuring into positional (centroid displacement), dispersive
(functional dispersion), and boundary (convex hull volume) components.
Tests each component against two null models: a sampling null model
(individuals or replicates reassigned between communities) and a
stratified trait-permutation null model, with a single global test when
many communities are compared. Functional entities (species with similar
traits) help detect replacement among similar species, and species-level
leverage identifies the taxa driving functional shifts. Supports both
temporal (paired) and spatial (pairwise) comparisons.
