When do Janzen–Connell effects matter? A phylogenetic meta‐analysis of conspecific negative distance and density dependence experiments

X Song, JY Lim, J Yang, MS Luskin - Ecology Letters, 2021 - Wiley Online Library
Abstract The Janzen–Connell (J‐C) hypothesis suggests that specialised natural enemies
cause distance‐or density‐dependent mortality among host plants and is regarded as an …

Bias in the detection of negative density dependence in plant communities

M Detto, MD Visser, SJ Wright, SW Pacala - Ecology Letters, 2019 - Wiley Online Library
Regression dilution is a statistical inference bias that causes underestimation of the strength
of dependency between two variables when the predictors are error‐prone proxies (EPPs) …

Plant diversity increases with the strength of negative density dependence at the global scale

Is variation in conspecific negative density dependence driving tree diversity patterns at large scales?

L Hülsmann, RA Chisholm, F Hartig - Trends in Ecology & Evolution, 2021 - cell.com

Negative density dependence is stronger in resource‐rich environments and diversifies communities when stronger for common but not rare species

JA LaManna, ML Walton, BL Turner… - Ecology Letters, 2016 - Wiley Online Library
Conspecific negative density dependence is thought to maintain diversity by limiting
abundances of common species. Yet the extent to which this mechanism can explain …
