Description: Standardises and facilitates the use of eleven established
        stability properties that have been used to assess systems’
        responses to press or pulse disturbances at different
        ecological levels (e.g. population, community). There are two
        sets of functions. The first set corresponds to functions that
        measure stability at any level of organisation, from individual
        to community and can be applied to a time series of a system’s
        state variables (e.g., body mass, population abundance, or
        species diversity). The properties included in this set are:
        invariability, resistance, extent and rate of recovery,
        persistence, and overall ecological vulnerability. The second
        set of functions can be applied to Jacobian matrices. The
        functions in this set measure the stability of a community at
        short and long time scales. In the short term, the community’s
        response is measured by maximal amplification, reactivity and
        initial resilience (i.e. initial rate of return to
        equilibrium). In the long term, stability can be measured as
        asymptotic resilience and intrinsic stochastic invariability.
