Unraveling the temporal dependence of ecological interaction measures
Javier Aguilar, Samir Suweis, Amos Maritan +1
Identifying the network of species interactions is a fundamental step toward understanding ecosystem stability and biodiversity. However, the interpretability of empirical interact…
Noise-induced excitability: bloom, bust and extirpation in autotoxic population dynamics
Pablo Moreno-Spiegelberg, Javier Aguilar
Species populations often modify their environment as they grow. When environmental feedback operates more slowly than population growth, the system can undergo boom-bust dynamics,…
Numerical methods for quasi-stationary distributions
Sara Oliver-Bonafoux, Javier Aguilar, Tobias Galla +1
In stochastic processes with absorbing states, the quasi-stationary distribution provides valuable insights into the long-term behaviour prior to absorption. In this work, we revis…
The Limits of Inference in Complex Systems: When Stochastic Models Become Indistinguishable
Javier Aguilar, Miguel A. Muñoz, Sandro Azaele
Robust inference for stochastic dynamical systems is often hampered by sparse sampling and the absence of closed-form likelihoods. We introduce a Monte Carlo path-inference framewo…
