... These forms of natural disturbance are often described as pulses, which are abrupt events that alter ecosystem dynamics through changes in habitat and/or resource availability and are followed by a period of reorganization (Bengtsson 2002, Jentsch andWhite 2019). Smallscale, frequent pulse disturbances can generate canopy gaps and alter understory vegetation (Canham and Marks 1985, Collins et al. 1985, Runkle 1990, Oliver and Larson 1996. Canopy gaps increase light availability, alter temperature and moisture regimes, reduce leaf litter cover and depth, and change vegetation structure on the forest floor (Gray et al. 2002, Ishizuka et al. 2002, Fahey and Puettmann 2007, Perry and Herms 2016b, Perry et al. 2018. ...
... While such models have been developed for many ecological interactions (competition, predation, etc.), extensive attention has been dedicated to understanding how disturbances influence biological systems. A disturbance is defined as a discrete event in space and time that alters resources, substrata, or the physical environment, consequently disrupting community or population structure (Petraitis et al., 1989;White and Pickett, 1985). Despite what we now know about the importance of disturbances in structuring ecosystems, early models attempting to understand the dynamics of biological systems focused upon equilibrium conditions. ...
