How ecological niche breadth evolves is central to adaptation and speciation and has been
a topic of perennial interest. Niche breadth evolution research has occurred within …

▪ Abstract As better phylogenetic hypotheses become available for many groups of
organisms, studies in community ecology can be informed by knowledge of the evolutionary …

▪ Abstract Floral evolution has often been associated with differences in pollination
syndromes. Recently, this conceptual structure has been criticized on the grounds that …

Evolutionary adaptation to temperature and climate depends on both the extent to which
organisms experience spatial and temporal environmental variation (exposure) and how …

Insects other than bees (ie, non-bees) have been acknowledged as important crop
pollinators, but our understanding of which crop plants they visit and how effective they are …

The mutually beneficial interactions between plants and their animal pollinators and seed
dispersers have been paramount in the generation of Earth's biodiversity. These mutualistic …

Classic theory relates herbivore pressure to the ecology and evolution of plant defenses.
Here, we summarize current trends in the study of plant–herbivore interactions and how they …

▪ Abstract Endophytic fungi living asymptomatically within plant tissues have been found in
virtually all plant species. Endophytes are considered plant mutualists: They receive nutrition …

The origin of new homoploid species via hybridization is theoretically difficult because it
requires the development of reproductive isolation in sympatry. Nonetheless, this mode is …

Trees do not form a natural group but share attributes such as great size, longevity, and high
reproductive output that affect their mode and tempo of evolution. In particular, trees are …
