The concept of ecological stability emerged in the first half of the 20th century. With the advancement of theoretical ecology in the 1970s, the usage of the term has expanded to a wide variety of scenarios. This overuse of the term has led to controversy over its definition and implementation. [3]
He even assumes that the members of a biocoenosis feature "specific mutual relations that are vital for their life" (ibid.: 268), whereby this mutual "bond either exists directly from organism to organism or operates indirectly by the medium of vitally created modifications of the physiographic conditions of the biotope" (Thienemann 1941: 105).
Hysteresis is an important concept in alternative stable state theory. In this ecological context, hysteresis refers to the existence of different stable states under the same variables or parameters. Hysteresis can be explained by "path-dependency", in which the equilibrium point for the trajectory of "A → B" is different from for "B → A ...

The balance of nature, also known as ecological balance, is a theory that proposes that ecological systems are usually in a stable equilibrium or homeostasis, which is to say that a small change (the size of a particular population, for example) will be corrected by some negative feedback that will bring the parameter back to its original "point of balance" with the rest of the system.
Resistance is one of the major aspects of ecological stability.Volker Grimm and Christian Wissel identified 70 terms and 163 distinct definitions of the various aspects of ecological stability, but found that they could be reduced to three fundamental properties: "staying essentially unchanged", "returning to the reference state...after a temporary disturbance" and "persistence through time of ...
As Harold J. Morowitz (1992) explains it, life is a property of an ecological system rather than a single organism or species. [16] He argues that an ecosystemic definition of life is preferable to a strictly biochemical or physical one.
An ecological network is a representation of the biotic interactions in an ecosystem, in which species (nodes) are connected by pairwise interactions (links). These interactions can be trophic or symbiotic .
