Figure 2 from: Schwerk A, Szyszko J (2011) Model of succession in degraded areas based on carabid beetles (Coleoptera, Carabidae). ZooKeys 100: 319-332. https://doi.org/10.3897/zookeys.100.1534

Figure 2 - Schematic illustration of the model. Succession starts from an 'initial degradation level', followed by a facultative 'delay phase' (characterized by the time of 'delay'). The optional 'delay phase' is followed by an 'increase phase' (characterized by the 'increase rate'), and a 'stagnation phase' in which the succession process runs towards a 'recovery level'. The type of area, origin of vegetation, and landscape-related aspects are assumed to influence the trajectory of succession.
