Lower within-community variance of negative density dependence increases forest diversity. [PDF]
PLoS ONE, 2015 Local abundance of adult trees impedes growth of conspecific seedlings through host-specific enemies, a mechanism first proposed by Janzen and Connell to explain plant diversity in forests.

Are we missing the forest for the trees? Conspecific negative density dependence in a temperate deciduous forest. [PDF]
PLoS ONE, 2021 One of the central goals of ecology is to determine the mechanisms that enable coexistence among species. Evidence is accruing that conspecific negative density dependence (CNDD), the process by which plant seedlings are unable to survive in the area ...

Negative density dependence regulates two tree species at later life stage in a temperate forest. [PDF]
PLoS ONE, 2014 Numerous studies have demonstrated that tree survival is influenced by negative density dependence (NDD) and differences among species in shade tolerance could enhance coexistence via resource partitioning, but it is still unclear how NDD affects tree ...

Contribution of conspecific negative density dependence to species diversity is increasing towards low environmental limitation in Japanese forests [PDF]
Scientific Reports, 2021 Species coexistence is a result of biotic interactions, environmental and historical conditions. The Janzen-Connell hypothesis assumes that conspecific negative density dependence (CNDD) is one of the local processes maintaining high species diversity by

Integrating conspecifics negative density dependence, successional and evolutionary dynamics: Towards a theory of forest diversity [PDF]
Communications BiologyTree successional diversity is evident even to casual observers and has a well-understood physiological basis. Various life history trade-offs, driven by interspecific variation in a single trait, help maintain this diversity.

Forest Ecosystems, 2023 Conspecific negative density dependence (CNDD) is a potentially important mechanism in maintaining species diversity. While previous evidence showed habitat heterogeneity and species’ dispersal modes affect the strength of CNDD at early life stages of ...

Assessing the impact of abiotic and biotic factors on seedling survival in an African montane forest
Frontiers in Forests and Global Change, 2023 Tree seedling dynamics underpin subsequent forest structure and diversity as different species/guilds respond variously to abiotic and biotic stresses.

Spatial patterning of Wyoming big sagebrush indicates negative density dependence
Ecosphere, 2022 Plants reflect resource use in their spatial patterning. Competition for limited resources—such as available soil water in a dryland ecosystem—drives establishment, growth, and mortality, resulting in shifts of spatial arrangement over time.

Estimating competition in metacommunities: accounting for biases caused by dispersal
Methods in Ecology and Evolution, 2023 Estimating the strength of interactions among species in natural communities has always been a challenge for empirical ecologists. Sessile organisms, like plants or corals, often occur in metacommunities where they compete only with their immediate ...
