%description
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>.
