Among the external disturbances, competition, delayed supply by the regular supplier, and skilled labor shortage were found to be the most significant ones, while financial obstacle was found to be the least significant in terms of their influence on the operational system.
At high larval density, disturbance during frequent encounters of larvae may retard development which would be interference competition.
Climate coupled with factors such as disturbance and competition can affect the physiology and growth of trees, including processes such as regeneration and recruitment (Paul et al. 2014).
Gap influence appears to be limited to areas where ruderal or competitor species are able to replace stress-tolerator species, likely due to elimination or reduction of these species by physical disturbance or competition.
Alternatively, the nematodes could also have migrated from the surface to depth to avoid disturbance and competition or to take profit from the newly created habitat at depth of the biologically mixed treatments.
This axis makes sense when considering how stress, disturbance and competition vary across the growing season in many systems (Fig. 1): early in the season when abiotic stress and disturbance are high, but competition low, an early-flowering, rapid-growth and comparatively low-investment strategy allows species to grow and reproduce quickly before periods of strong competition begin.
High disturbance intensities alleviate competition, and this is probably why recruits' ACS growth is high just after disturbance in the enhanced growth conditions (Herault et al. 2010) and then quickly decrease (high βs, Fig. 1d and e).
To address these questions, we used non-parametric multiplicative regression to develop provisional climate niche models for nine regionally dominant tree species and two shrub functional types, and coupled output from these models with a stochastic forest landscape model that simulates interactions between forest disturbance, dispersal, establishment, competition, growth, and mortality.
Only a few studies using climate niche modeling approaches have attempted to integrate the role of disturbance, dispersal, or competition (Tucker et al. 2012; Crimmins et al. 2014, Maguire et al. 2015), in part due to complexities involved in integrating complex processes into non-process-based models.
However, herbivory [via both escape from co-evolved specialist herbivores, and suppression by newly acquired generalist herbivores] is not the only determinant of plant invasions: invasion success also will be affected by competition, disturbance, and the physical traits of the habitat being invaded [10], [18], [20], [23], [24], [25].
