| Antifragility |
Antifragility is a property that enhances the system’s functional capacity to response to external perturbations (Taleb, 2018). In other words, a system is Antifragile if it benefits from environmental variability, works better after being disturbed |
| Ascendency |
It is a measure of the magnitude of the information flow through an ecosystem’s network framework |
| Complexity |
A system is complex either it presents a sufficient number of components with strong enough interaction or it changes in a velocity comparable to the observer’s time scale, and in most cases both. Forests as a system and forest management, certainly occupy a high position in the complexity gradient (Filotas et al., 2014). It is measure as the product of emergence and self-organization |
| Criticality |
Criticality is a regime in which the system is in dynamic scale invariance (power law in frequency space) and in an “optimum” balance between robustness and adaptability (scale coefficient around −1) |
| Emergence |
We can define information emergence E as the rate of information transformation. Can be measure as Shannon information |
| Fisher information |
Fisher information may be understood as the quality of a measurement-inference process. It is related to tangential velocity and acceleration in phase space, hence with stability |
| Homeostasis |
Fossion and co-workers (Fossion, Rivera & Estanol, 2018) have related homeostasis (physiological resilience?) to pairs of physiological variables, one to be controlled (the one that remains in homeostasis) and another one that controls the former. The main idea is that in order to have a homeostatic physiological variable (normal), the body must use other variables (right fat-tailed) to absorb a random injection of matter, energy, information or any combination of them from the environment |
| Integrity |
Is a measure of the state of the ecosystems in terms of its structure, composition and function |
| Lévy-flight |
Fat-tailed foraging pattern characterized by local space exploration (normal distributed) with some large “flights” for non-local exploration |
| Persistence |
Persistence is the time for a variable to remain in the same state before changing to a different one (Pimm & Pimm, 1991). Persistence is a measure of a system’s capacity to preserve itself over time (Loreau et al., 2002) |
| Robustness |
Robustness relates to the durability of the stability of the environment. Robustness is then a measure of the amount of disturbance an ecosystem can endure before it changes to a different state (Loreau et al., 2002). The more robust the food web is, the more stable it is |
| Self-organization |
Is the complement of emergence (1 − E) and represent the capacity of the system for increase its organization |
