4.2.1 Successional Stage There are considerable differences in structure and
ecosystem functioning between young, mature, and old forests. In even-aged
forests, for instance, growth declines after reaching a peak relatively early in a
stand's life (which typically coincides with the maximum development of leaf area:
Ryan et al. 1997). This decline is thus both size- and age related (Weiner and
Thomas 2001). Tree height, diameter, and biomass increase through time while
tree density ...

in young stands is expected to benefit a variety of species, ecosystem processes,

diversity of tree sizes and associated canopy conditions, as it leads to increases
in tree diameter growth along gap edges, consistent with previous studies (Chen

A further comparison in which BP change in adults from 52 western populations
and four nonindustrialized populations confirmed little or no agerelated changes
in the nonindustrialized populations was in marked contrast to the increases
seen ... were related to faster agerelated increases in BP and pulse pressure
during midlife, suggesting that detrimental early life influences on vascular
structure and function may increase vulnerability to the effects of ageing on the
arterial tree [43].

With the possible exception of tree-ring chronologies developed from even-aged
stands or narrow-age classes of trees, the yearly sample size of m indices in a
tree-ring chronology can be expected to diminish backward in time as younger
trees drop out of the series. As the sample size ... This increase in variance is
largely a function of decreasing sample size, which is independent of changes in
the variance owing to environmental influences on radial growth. This problem of

have been reported—increased, decreased, or unchanged sizes as a function of
aging (Hinds & McNelly, 1977; Kemper, 1984; Peters & Vaughan, 1981). Some of
these discrepancies may be accounted for by technical problems of fixation,
postmortem change, and the like, mentioned above. However, even when
technical procedures seem not to confound experimental findings, changes in
cell size are not necessarily uniform. In a study from the author's laboratory, cited
above, Willott ...

These models are capable of simulating species changes by considering the
differential birth, growth, and death of individual trees as a function of species
response to temperature, moisture, light, and nutrients. The computer code for
these models is readily available, the system is clearly modularized, and the
documentation is extensive (Botkin, 1992). Species composition, size and age
structure for particular regions can be projected under climate change scenarios.
