Impacts of large herbivores on terrestrial ecosystems
Large herbivores play unique ecological roles and are disproportionately imperiled by
human activity. As many wild populations dwindle towards extinction, and as interest grows …

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

ForestGEO: Understanding forest diversity and dynamics through a global observatory network
ForestGEO is a network of scientists and long-term forest dynamics plots (FDPs) spanning
the Earth's major forest types. ForestGEO's mission is to advance understanding of the …

Unveiling the transition from niche to dispersal assembly in ecology
A central goal in ecology is to understand what maintains species diversity in local
communities. Classic ecological theory, posits that niches dictate the maximum number of …

Pervasive within-species spatial repulsion among adult tropical trees
For species to coexist, performance must decline as the density of conspecific individuals
increases. Although evidence for such conspecific negative density dependence (CNDD) …

Is variation in conspecific negative density dependence driving tree diversity patterns at large scales?
Half a century ago, Janzen and Connell hypothesized that the high tree species diversity in
tropical forests is maintained by specialized natural enemies. Along with other mechanisms …

Modelling how negative plant–soil feedbacks across life stages affect the spatial patterning of trees
In this work, we theoretically explore how litter decomposition processes and soil-borne
pathogens contribute to negative plant–soil feedbacks, in particular in transient and stable …

The Forests of Barro Colorado Island and the Neutral Theory of Biodiversity
R Chisholm - 2024 - smithsonian.figshare.com
Neutral theory in ecology came to prominence with the publication of Stephen Hubbell's

Closing the gap in the Janzen–Connell hypothesis: What determines pathogen diversity?
The high tree diversity in tropical forests has long been a puzzle to ecologists. In the 1970s,
Janzen and Connell proposed that tree species (hosts) coexist due to the stabilizing actions …

The functional form of specialised predation affects whether Janzen–Connell effects can prevent competitive exclusion
DJB Smith - Ecology Letters, 2022 - Wiley Online Library
Abstract Janzen–Connell effects (JCEs), specialised predation of seeds and seedlings near
conspecific trees, are hypothesised to maintain species richness. While previous studies …
