Negative density-dependent recruitment of seedlings, that is, seeds of a given species are less likely to become established seedlings if the density of that species is high, has been proposed to be an important mechanism contributing to the extraordinary diversity of tropical tree communities because it can potentially prevent any particular species from usurping all available space, either in close proximity to seed sources or at relatively larger spatial scales. However, density-dependent… Expand

Widespread density-dependent seedling mortality promotes species coexistence in a highly diverse Amazonian rain forest.
• Biology, Medicine
• Ecology
• 2010
The results suggest that the local biotic neighborhood is a strong influence on early seedling survival for species that range widely in their abundance and life history, and the role of density-dependent seedling dynamics in promoting and maintaining diversity in understory seedling assemblages. Expand
Neighborhood and community interactions determine the spatial pattern of tropical tree seedling survival.
• Biology, Medicine
• Ecology
• 2007
It is concluded that negative density dependence could promote species coexistence in this rain forest community but that the scale dependence of interactions differs between rare and common species. Expand
Prevalence and strength of density-dependent tree recruitment.
• Biology, Medicine
• Ecology
• 2015
The analysis of over a million seedling-to-sapling recruitment observations of 50 species from the eastern United States provides direct evidence that density dependence reaulates opulation dynamics of tree species in eastern U.S. forests. Expand
Seasonal differentiation in density-dependent seedling survival in a tropical rain forest
• Biology
• 2012
The results demonstrate that the strength of density-dependent seedling survival can vary between seasons and among species in tropical forests and suggest that local-scale negative density dependence (NDD) tends to be stronger in the dry than wet season in the Xishuangbanna tropical forest. Expand
Multiple stage recruitment limitation and density dependence effects in two tropical forests
• Biology
• Plant Ecology
• 2015
Evidence is found that recruitment limitation operates at multiple stages and is density dependent in these two tropical forests, and results suggest that these effects may be stronger in the high-diversity community. Expand
Seed limitation and the coexistence of pioneer tree species
Seed limitation, defined as the failure of seeds to arrive at sites favorable for recruitment, may be a critical force structuring plant communities. When seed limitation is strong, interspecificExpand
Conspecific negative density‐dependent mortality and the structure of temperate forests
• Biology
• 2014
Results demonstrate that negative conspecific density-dependent mortality of seedlings could generate the spatial patterns observed at later life stages, which may contribute to the maintenance of tree diversity in temperate forests, just as others have demonstrated for tropical forests. Expand
Conspecific Negative Density Dependence and Forest Diversity
• Geography, Medicine
• Science
• 2012
It is found that most species experienced conspecific negative density dependence (CNDD), but there was little effect of heterospecific density, and abundant species exhibited weaker CNDD than rarer species, and species-rich regions exhibited stronger C NDD than species-poor regions. Expand
High seed dispersal rates in faunally intact tropical rain forest: theoretical and conservation implications
• Biology
• 2001
Comparing the species lists of tree plots with those of nested seedling plots in rain forest at Gunung Palung found that the proportion of local seedlings arising from active dispersal events was high and local seedling species richness was not limited by the local richness of adults. Expand
Seedling survival declines with increasing conspecific density in a common temperate tree
The results illustrate the importance of negative density-dependent feedbacks resulting from the soil microbial community in a common and ecologically important temperate tree species. Expand

SEEDLING DENSITY DEPENDENCE PROMOTES COEXISTENCE OF BORNEAN RAIN FOREST TREES
• Biology

Evidence for the dependence of seedling survival on the abundance of conspecific trees and seedlings over both wide and local scales, in a species-rich Bornean rain forest constitutes strong evidence that density-dependent processes contribute to coexistence in this diverse rain forest community.

It is concluded that other factors than seed predation limit the abundance of tropical tree species and prevent single-species dominance. Expand

• E. Schupp

The model hypothesizes that mortality near parents is virtually complete, recruitment is limited to areas at some distance from conspecifics, and adults are more evenly spaced than expected from the pattern of seedfall. Expand

Most recruitment patterns did not fit the prediction of Janzen and Connell; however, two to three of the most common species may have reached densities at which a depression in local recruitment is regulating abundance. Expand
Herbivores and the Number of Tree Species in Tropical Forests
Any event that increases the efficiency of the predators at eating seeds and seedlings of a given tree species may lead to a reduction in population density of the adults of that species and/or to increased distance between new adults and their parents. Expand

The more diverse an area in the forest is, the higher is the overall rate of increase of the trees in that area, although sheer crowding has by itself a negative effect. Expand

• Biology
• The American Naturalist
• 1984
A review of 24 data sets on tropical woody plants showed that most evidence indicates either density-dependence or distance-Dependence in progeny mortality, as hypothesized by Janzen and Connell, and some positive evidence also exists for the minimum critical distance effect for tropical trees.

The study indicates that the location where seedlings survive is greatly influenced by pathogen activity, and is expected to occur away from the parent tree, in shaded conditions for trees with distance— and/or density—dependent mortality, and in light—gaps for all trees studied here. Expand

Stochastic effects caused by BCI's more rapid tree turnover may contribute to a larger variance in diversity from quadrat to quadrat at BCI, although they are not sufficient to explain why BCI has fewer than half as many tree species as Pasoh. Expand
