A broad and diversified group of compounds, secondary metabolites, are known to govern
species interactions in ecosystems. Recent studies have shown that secondary metabolites …

Tannins are the most abundant secondary metabolites made by plants, commonly ranging
from 5% to 10% dry weight of tree leaves. Tannins can defend leaves against insect …

Since the 19th century the phytochemistry of the Salicaceae has been systematically
investigated, initially for pharmaceutical and later for ecological reasons. The result of these …

We present evidence that the heritable genetic variation within individual species, especially
dominant and keystone species, has community and ecosystem consequences. These …

In Alien Species and Evolution, biologist George W. Cox reviews and synthesizes emerging
information on the evolutionary changes that occur in plants, animals, and microbial …

On the basis of physiological and ecological costs of defense allocation, most plant defense
theories predict the occurrence of trade-offs between resource investment in different types …

Abstract In poplar (Populus spp.), the major defense phenolics produced in leaves are the
flavonoid-derived proanthocyanidins (PAs) and the salicin-based phenolic glycosides …

Fundamental links between genes and ecosystem processes have remained elusive,
although they have the potential to place ecosystem sciences within a genetic and …

In order to study condensed tannin synthesis and its induction by herbivory, a
dihydroflavonol reductase (DFR) cDNA was isolated from trembling aspen (Populus …

Genetic and environmental variability, and their interactions, influence phytochemical
composition and, in turn, herbivore performance. We evaluated the independent and …
