Forest ecologists often evaluate how well the species composition of saplings in the understory matches that of the canopy: absence of juveniles suggests that a tree species is suffering population decline. Here we offer a theoretical and empirical test of this assertion using data from a 50‐ha census plot in Panama. Theory indicates that higher rates of population change, λ, lead to more steeply declining size distributions (more juveniles relative to adults). But other parameters also affect… 

Do current stem size distributions predict future population changes? An empirical test of intraspecific patterns in tropical trees at two spatial scales

It is concluded that some measures of intraspecific differences in size distribution are potentially informative of population trends within forests but have limited utility across broader spatial scales.

Unimodal Tree Size Distributions Possibly Result from Relatively Strong Conservatism in Intermediate Size Classes

Modal size distributions do not necessarily indicate either population decline or shade-intolerance, but there were statistically significant, important quantitative differences between observed and projected equilibrium size distributions in most species, suggesting that these populations are not at equilibrium and that this forest is changing over time.

How do size distributions relate to concurrently measured demographic rates? Evidence from over 150 tree species in Panama

Abstract: In stable populations with constant demographic rates, size distributions reflect size-dependent patterns of growth and mortality. However, population growth can also affect size

Demographic Properties Shape Tree Size Distribution in a Malaysian Rain Forest

The observed size distributions were not simply correlated with the rate of population increase but were related to demographic properties such as size growth rate and mortality, in accordance with those predicted by foliage partitioning theory.

GAP‐DEPENDENT RECRUITMENT, REALIZED VITAL RATES, AND SIZE DISTRIBUTIONS OF TROPICAL TREES

The authors' analyses suggest that there are not large numbers of functionally equivalent species at either extreme of the regeneration continuum, rather, there are very few extremely shade-tolerant and extremely light-demanding species.

Effects of flood frequency and duration on the allometry of community-level stem size-density distributions in a floodplain forest.

As frequency and duration of disturbances increased, several small tree species were eliminated from forest plots and the persistent species increased in their size, corresponding with overall decreases in stem density, increases in average stem size, and reductions in both the Y-intercept and slope terms of the community-level SDDs.

Effects of flood frequency and duration on the allometry of community-level stem size-density distributions in a floodplain forest.

This study adds to a growing list of examples suggesting that theories related to forest community composition and biomass must account for both the broader effects of disturbances as well as the underlying biochemical processes that regulate plant growth.

Tree species differentiation in growth, recruitment and allometry in relation to maximum height in a Bornean mixed dipterocarp forest

Spling recruitment per unit basal area declined greatly with increasing maximum height, consistent with model predictions of the traits required for the stable coexistence of species at different heights within the canopy, and understorey species showed adaptive morphology to deep shade.

Ecological interpretation of multiple population size structures in trees: The case of Araucaria angustifolia in South America

The usefulness of tree population size distributions in evaluating the conservation status of populations of an endangered tree species is examined and expectations derived from two complimentary views of the ecology of rainforest trees are set.

Importance of a single population demographic census as a first step of threatened species conservation planning

This work modelled a situation when either seed production or survival of emerging seedlings occur intermittently and found that when recruitment occurs intermittently, the population size frequency distribution deviates from inverse J-curve, but no gaps in size classes are observed.

The Population Dynamics of a Long-Lived Conifer (Pinus palustris)

It is suggested that longleaf pine maintains the environment in an open state suitable for its own regeneration by transmuting a localized disturbance into a widespread disturbance (ground fires) and this regeneration pattern represents a spatial analogue to stochastic boundedness over time, and it may enhance the local persistence of longleaf Pine populations.

Density Dependence in Two Understory Tree Species in a Neotropical Forest

Density dependence was examined in two species of neotropical treelets, Faramea occidentalis and Desmopsis panamensis, in a 50—ha plot on Barro Colorado Island in Panama, and both showed no density dependence in survival nor in growth.

Stand development processes from various initial densities were simulated employing a one-sided competition model of the size structure dynamics of trees in which the size growth rate and the

A study of the structure and floristics at a transition zone from a monodominant to a more diverse forest in the African humid tropics was conducted to elucidate the mechanisms maintaining floristic

A simple model predicts runoff and soil moisture content from rainfall, potential evapotranspiration, and fixed characteristics of the soil may enable one to infer phenological rhythms of the forest in years past from rainfall records.
