“…The negative relationship between DBH and mortality risk has been documented repeatedly (Coomes et al, 2003;Lorimer, 1983;Piovesan et al, 2005), especially in stem exclusion phase (Luis and Fonseca, 2004). Size is a good estimator for competitive ability and physiological status, especially in even-aged stands where small differences in size may suppose strong changes in canopy position once competitive hierarchies are established (Peet and Christensen, 1987). This fact is supported by the inclusion of height in both models.…”

“…Mortality driven changes in canopy composition play a key role in shaping forest composition and structure. This fact may be especially relevant in some forest stand stages such as at the stem exclusion phase (Oliver and Larson, 1996), where the highest competition levels and tree death rates occur (Peet and Christensen, 1987).…”

“…Regular mortality is associated with a progressive reduction in vitality. It can result either from competition for light, water and soil nutrients (Peet and Christensen, 1987) or from senescence defined as a decrease in resource utilization efficiency because of limitations in respiratory efficiency or hydraulic conductance (Gower et al, 1996;Hubbard et al, 1999;MacFarlane et al, 2002). Irregular mortality can be described as mortality caused by random events or hazards, e.g.…”

“…A dynamic equation was developed for predicting the reduction in tree number due to density-dependent mortality, which is mainly caused by competition for light, water and soil nutrients within a stand [79]. According to Clutter et al [31], most mortality analyses are based on the values of age and number of trees per hectare at the beginning and at the end of the period involved.…”
