What traits govern root sprouting in temperate herbs?
The ability is most common in dry, open habitats, and most vigorous where disturbance is frequent.

Horizontal gene transfer found between moss plastids
The transfer may have been triggered by the large-scale liming of acidic mires.
Hakea drought resistance determined by climate factors rather than functional traits
Cavitation resistance appears to be genetic, making it useful as a predictor of drought resistance.
Local adaptation of invasive species occurs in clonal plants too
In transplant experiments, closely-related sexual and asexual species both showed evidence of local adaptation.
New Equisetum phylogeny provides insight into an ancient lineage
The first divergences among horsetail species occurred with the break-up of Pangaea.
“Mythical” Jurassic angiosperms perhaps not so mythical
Modelling that accounts for an incomplete fossil record doesn’t reject a pre-Cretaceous origin.
A new spin on Darwin’s “abominable mystery”
Darwin may indeed not have been referring to angiosperms broadly in his famous words to his friend.
Colder temperatures better for long-term maize seed storage
Seeds were found to vary from one accession to the next in their cold storage longevity.
Historical trends in herbarium specimens could cause misleading observations
Extra care should be taken to avoid misinterpretation of data when looking at centuries-spanning specimens.
Leaf composites better than single leaves at capturing species differences
Accurate species prediction depended on adequate sampling and straightforward genetic background.
