..Here, I expand on the thesis that diversity is maintained by the interaction between predation and competition, such that strong top-down forcing reduces competition, allowing coexistence. ..

..These behaviors are interpreted as adjustments to the unrelenting deprivation associated with bottom-up limitation in a predator-free environment. ..

..The densities of seedlings and saplings of canopy trees are severely reduced on herbivore-affected islands, providing evidence of a trophic cascade unleashed in the absence of top-down regulation...

..Our results suggest that the best, and perhaps only, way to prevent compositional change and probable loss of diversity in tropical tree communities is to prohibit hunting...
- Enemies maintain hyperdiverse tropical forests

..I conclude that Janzen and Connell were essentially correct and that diversity maintenance results from top-down forcing acting in a spatially nonuniform fashion...
- Are all seeds equal? Spatially explicit comparisons of seed fall and sapling recruitment in a tropical forest
Nicholas School of Environment, Duke University, Durham, NC, USA

- Elevational ranges of birds on a tropical montane gradient lag behind warming temperatures
Nicholas School of the Environment, Duke University, Durham, North Carolina, United States of America
PLoS ONE 6:e28535. 2011
..There are few data to suggest that they do. Yet, the greatest loss of species from climate disruption may be for tropical montane species...
