    Pathogens and insect herbivores drive rainforest plant diversity and composition. by Bagchi, R, Gallery, R, Gripenberg, S, Gurr, S, Narayan, L, Addis, C, Freckleton, R, Lewis, O

    Published 2014
    “…Our study provides an overall test of the Janzen-Connell hypothesis and demonstrates the crucial role that insects and pathogens have both in structuring tropical plant communities and in maintaining their remarkable diversity.…”

    Pathogens and insect herbivores drive rainforest plant diversity and composition by Bagchi, R, Bagchi, R, Gallery, R, Gallery, R, Gripenberg, S, Gripenberg, S, Gurr, S, Gurr, S, Narayan, L, Addis, C, Freckleton, R, Lewis, O

    Published 2014
    “…Tropical forests are important reservoirs of biodiversity, but the processes that maintain this diversity remain poorly understood. The Janzen-Connell hypothesis suggests that specialized natural enemies such as insect herbivores and fungal pathogens maintain high diversity by elevating mortality when plant species occur at high density (negative density dependence; NDD). …”

    Testing the Janzen-Connell mechanism: pathogens cause overcompensating density dependence in a tropical tree. by Bagchi, R, Swinfield, T, Gallery, R, Lewis, O, Gripenberg, S, Narayan, L, Freckleton, R

    Published 2010
    “…The Janzen-Connell hypothesis is a leading explanation for plant-species diversity in tropical forests. …”

    A damage spreading transition in a stochastic host–pathogen system by Yael Fried, Yossi Ben-Zion, Nadav M Shnerb

    Published 2013-01-01
    “…One of the leading proposals for solving the biodiversity problem is the Janzen–Connell hypothesis, suggesting that the abundance of a species is limited by a host-specific exploiter. …”

    Effects of seed predators of different body size on seed mortality in Bornean logged forest by Hautier, Y, Saner, P, Philipson, C, Bagchi, R, Ong, R, Hector, A

    Published 2010

    Insect herbivory on seedlings of rainforest trees: Effects of density and distance of conspecific and heterospecific neighbours by Downey, H, Lewis, O, Bonsall, M, Fernandez, D, Gripenberg, S

    Published 2018
    “…The elevated rates of seedling herbivory at high densities of conspecifics documented in our study are consistent with the predictions of the Janzen–Connell hypothesis, which explains how so many plant species can coexist in tropical forests. …”

    Global woodland structure from local interactions: new nearest-neighbour functions for understanding the ontogenesis of global forest structure by Arne Pommerening, Hongxiang Wang, Zhonghua Zhao

    Published 2020-04-01
    “…Abstract Background A number of hypotheses and theories, such as the Janzen-Connell hypothesis, have been proposed to explain the natural maintenance of biodiversity in tropical and temperate forest ecosystems. …”

    Published 2016-01-01
    “…This, however, contrasts with the predictions of the Janzen-Connell hypothesis and commonly reported intraspecific negative plant-soil feedback. …”

    Ecological consequences of primary and secondary seed dispersal on seed and seedling fate of Dipteryx oleifera (Fabaceae) by Javier Ruiz, Douglas H Boucher, Luis F Chaves, Cherryl Ingram-Flóres, Delvis Guillén, René Tórrez, Oscar Martínez

    Published 2010-09-01
    “…The distribution of D. oleifera seedlings is consistent with the Janzen-Connell Hypothesis and depends on primary dispersal by bats, secondary dispersal by terrestrial vertebrates, a seed masking effect and, the constant threat of insect herbivores on seedlings. …”
