Leptosporangiate ferns have three times more cryptochrome receptors than their nearest relatives.
Stomatal trait variation may have evolved more in response to pathogens than climate, or climate may be affecting the traits in unexpected ways.
Both light capture and phosphorous acquisition affected the success of nitrogen-enriched plants.
Haplotype analysis showed a clear distinction between Andean and lowland landraces.
Both tannin distribution and root anatomy showed distinct patterns depending on mycorrhiza type.
More independence in trait adaptation may mean a greater leeway to adapt to changing climate.
Exudates did bind soil to the roots, but were unable to compensate for the absence of root hairs.
Herbaria are an under-used resource for large phylogenies.
Accounting for the historical range can help explain trait variation in some cases.
Surprisingly, life history, soil nutrients, and range size were not key determinants.
The ability is most common in dry, open habitats, and most vigorous where disturbance is frequent.
The transfer may have been triggered by the large-scale liming of acidic mires.
Cavitation resistance appears to be genetic, making it useful as a predictor of drought resistance.
In transplant experiments, closely-related sexual and asexual species both showed evidence of local adaptation.
