Data_Jena_hierarchical_structure

<p>All plots in the Jena Experiment were arranged into 4 blocks, each containing 18–20 plots. Plots were sown along a gradient of 1, 2, 4, 8, or 16 species, comprising a total of 462 populations. The biomass of each species sown in a plot was recorded annually from 2003 to 2024, except in 2004. The entire dataset forms a four-level hierarchy: Level 1: population, Level 2: community, Level 3: block, and level 4: overall data. 
This dataset describes the four-level structure. Each row corresponds to a population identifier ( matching the same row <code>Jena_hierarchical_data</code>), and records the names of block, plot and species to which that population belongs.</p>

datasets

Provides functions to to compute a continuum of information-based measures
for quantifying the temporal stability of populations, communities, and ecosystems,
as well as their associated synchrony, based on species (or species assemblage)
biomass or other key variables. When biodiversity data are available, the package
also enables the assessment of the corresponding diversity–stability relationships.
All measures are applicable in both temporal and spatial contexts. The theoretical
and methodological background is detailed in Chao et al. (2025)
<doi:10.1101/2025.08.20.671203>.
