Incorporating animal behavior into seed dispersal models: implications for seed shadows.
Improved seed shadow prediction for animal-dispersed plants can be accomplished by incorporating spatially explicit information on disperser behavior and movements, using scales large enough to capture routine long-distance dispersal, and using dispersal kernels, such as mixture distributions, that account for spatially aggregated dispersal.

Aggregated Seed Dispersal by Spider Monkeys Limits Recruitment to Clumped Patterns in Virola calophylla
It is found that spatially aggregated seed deposition strongly influenced the spatial structure of later stages of a vertebratedispersed rain forest tree, Virola calophylla, and the clumped dispersion at sleeping and parental sites persisted to the seedling/sapling stage. Expand
A Multi-Forest Comparison of Dietary Preferences and Seed Dispersal by Ateles spp
Variation in plant community structure strongly influences dietary preferences, and hence, seed dispersal by spider monkeys, and thus, diffuse coevolution in spider monkey-plant relationships may be limited to few taxa at the generic and familial levels. Expand
Rate of tree carbon accumulation increases continuously with tree size
A global analysis of 403 tropical and temperate tree species shows that for most species mass growth rate increases continuously with tree size, which means large, old trees do not act simply as senescent carbon reservoirs but actively fix large amounts of carbon compared to smaller trees. Expand
Soil-related performance variation and distributions of tree species in a Bornean rain forest
Summary 1 Spatial distributions of tropical trees often correlate with environmental variation, suggesting that ecological sorting caused by niche differentiation may be important for maintainingExpand
Lack of host specificity leads to independent assortment of dipterocarps and ectomycorrhizal fungi across a soil fertility gradient.
It is shown that ectomycorrhizal fungi and tree communities in this Bornean rain forest assemble independently of host-specific interactions, raising questions about how mutualism shapes the realised niche. Expand
The Importance of Demographic Niches to Tree Diversity
Although demographic differences may foster coexistence, they do not explain any of the 16-fold variation in tree species richness observed across the tropics. Expand
Terrestrial Behavior of Ateles spp
Spider monkeys (Ateles spp.) are well known for their highly arboreal lifestyle, spending much of their time in the highest levels of the canopy and rarely venturing to the ground. To investigateExpand
Globally, functional traits are weak predictors of juvenile tree growth, and we do not know why
This paper presents a meta-analyses of the response of the immune system to repeated exposure to carbon monoxide poisoning in rats over a 12-month period and shows clear patterns of decline in the immune systems of rats exposed to carbon dioxide. Expand
