Pathogen mortality of tropical tree seedlings: experimental studies of the effects of dispersal distance, seedling density, and light conditions
SummaryWe present results of two experiments designed to identify the relative importance of dispersal distance, seedling density, and light conditions on pathogen-caused mortality of tropical treeExpand

Global climate and the distribution of plant biomes.
Biomes are areas of vegetation that are characterized by the same life-form. Traditional definitions of biomes have also included either geographical or climatic descriptors. This approach describesExpand

The influence of CO2 concentration on stomatal density
summary A survey of 100 species and 122 observations has shown an average reduction in stomatal density of 14.3% (SE ±2.2 %) with CO2 enrichment, with 74% of the cases exhibiting a reduction inExpand

On the Adaptive Value of Physiological Integraton in Colonal Plants
In clonal plants, genetically identical ramets arise from a common stolon or rhizome. Anatomical connection often allows physiological integration, the translocation of resources from a larger motherExpand

Ecological correlates of plant range size: taxonomies and phylogenies in the study of plant commonness and rarity in Great Britain
Recent simulations have shown that the lack of resolution to be found in taxonomic relative to phylogenetic classification systems only slightly inflates the probability of Type 1 errorExpand

Plant Foraging: A Marginal Value Model and Coiling Response in Cuscuta Subinclusa
Stems of the parasitic plant Cuscuta subinclusa (Convolvulaceae) discrim- inate among host species and invest in resource acquisition (coil around the stem of a host plant) relative to host qualityExpand

IDENTIFICATION OF SPECIFIC TREE SPECIES IN ANCIENT SEMI-NATURAL WOODLAND FROM DIGITAL AERIAL SENSOR IMAGERY
Remote sensing has great potential as a source of information on tree species. The classification approaches used commonly to extract species information from remotely sensed imagery typically aim toExpand

Seed size in tropical trees: a comparative study of factors affecting seed size in Peruvian angiosperms
Evolutionary comparative methods taking into account the potential effects of relatedness reveal that, among 202 species of animal-dispersed tropical woody angiosperms from Peru, large seeds may beExpand
