Commonness, rarity, and intraspecific variation in traits and performance in tropical tree seedlings.
One of the few rules in ecology is that communities are composed of many rare and few common species. Trait-based investigations of abundance distributions have generally focused on species-mean trait values with mixed success. Here, using large tropical tree seedling datasets in China and Puerto Rico, we take an alternative approach that considers the magnitude of intraspecific variation in tr...
متن کاملTaxonomic scale-dependence of habitat niche partitioning and biotic neighbourhood on survival of tropical tree seedlings.
In order to differentiate between mechanisms of species coexistence, we examined the relative importance of local biotic neighbourhood, abiotic habitat factors and species differences as factors influencing the survival of 2330 spatially mapped tropical tree seedlings of 15 species of Myristicaceae in two separate analyses in which individuals were identified first to species and then to genus....
متن کاملNeighbour-regulated mortality: the influence of positive and negative density dependence on tree populations in species-rich tropical forests
Halton A. Peters* Department of Biological Sciences, Stanford University, Stanford, CA 94305, USA *Correspondence: E-mail: hpeters@globalecology. stanford.edu Abstract Density-dependent mortality has long been posited as a possible mechanism for the regulation of tropical forest tree density. Despite numerous experimental and phenomenological investigations, the extent to which such mechanisms ...
متن کاملConspecific density dependence in seedlings varies with species shade tolerance in a wet tropical forest.
Density-dependent seedling mortality could increase with a species relative abundance, thereby promoting species coexistence. Differences among species in light-dependent mortality also could enhance coexistence via resource partitioning. These compatible ideas rarely have been considered simultaneously. We developed models of mortality as functions of irradiance and local conspecific density (...
متن کاملGrowth response and acclimation of CO2 exchange characteristics to elevated temperatures in tropical tree seedlings
Predictions of how tropical forests will respond to future climate change are constrained by the paucity of data on the performance of tropical species under elevated growth temperatures. In particular, little is known about the potential of tropical species to acclimate physiologically to future increases in temperature. Seedlings of 10 neo-tropical tree species from different functional group...
