  "Description": "Provides functions to compute a continuum of\ninformation-based measures for quantifying the temporal\nstability of populations, communities, and ecosystems, as well\nas their associated synchrony, based on species (or species\nassemblage) biomass, or other key variables. When biodiversity\ndata are available, the package also enables the assessment of\nthe corresponding diversity–stability and diversity–synchrony\nrelationships. All measures are applicable in both temporal and\nspatial contexts. The theoretical and methodological background\nis detailed in Chao et al. (2025)\n<doi:10.1101/2025.08.20.671203>.",
