Domain-specific¶
- Janzen-Connell Hypothesis
- The spatial gradient from near-zero survival beneath the crown to substantial survival at twenty or more meters is the model's primary empirical prediction, and it has been confirmed repeatedly in long-term forest plots — most directly by Augspurger's (1983) study of Platypodium elegans on Barro Colorado Island, Panama and the seedling-sowing experiments of Augspurger and Kelly (1984), and subsequently by large-scale census analyses (Comita et al. 2010, 2014) and fungicide-exclosure experiments (Bagchi et al. 2014) identifying soil-borne fungal pathogens as particularly important agents
This sourceComita and colleagues' Barro Colorado Island seedling census, which modelled survival for more than 30,000 seedlings of 180 species and found conspecific — but not heterospecific — neighbour density depressing survival, most strongly for rare species.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
