One way to preserve plants suffering from rising temperatures is to relocate them in new areas that have become suitable for them. But when a plant grows in the sands of a harsh desert, you don't want that habitat to...

Plants that have adapted to exploit human activity now depend on disturbance
Plants that have grown in partnership with human activity in meadows can be a great source of seeds for restoration projects, but their ability to germinate is also a problem.
Genetic variation in early fitness traits across European populations of silver birch
How will silver birch populations across Europe be affected by climate change?

How does Holly Oak compensate for losing leaves?
Defoliation had larger legacy effects than immediate effects.
A key protein may help trigger germination in Arabidopsis seeds
Seed germination is a critical step in the life cycle of flowering plants. Since seeds contain limited reserves, seed germination has to be tightly regulated to ensure that germination takes place in a suitable...

Daffodils and Snowdrops react differently to warming seasons
Daffodils and Snowdrops need the right temperatures in a few seasons to germinate. Will a changing climate cause problems?
Continuous variation in herkogamy in Mediterranean honeysuckle populations
Herkogamy, the spatial separation of sex organs in hermaphroditic plants, is thought to have evolved to reduce self-pollination and inbreeding within a population. Yet there has been little evidence to support these...
Achene heteromorphism in Bidens pilosa (Asteraceae): differences in germination and possible adaptive significance
Bidens pilosa L. (also known as cobbler’s pegs, farmer’s friend and burr marigold) is a noxious weed in many ecosystems worldwide. Across China, the plant can be found growing on roadsides and in fields and villages at...
What drives germination and seedling survival in an Afrotropical forest?
Hunting in otherwise intact tropical forests removes organisms from some trophic levels, which can change population and community dynamics at other levels. The preferred game species can be dispersers of seeds (e.g...
Morpho-physiological dormancy described in seeds of waterlilies (Nymphaea)
Substantial evidence supports morpho-physiological dormancy (MPD) as the basal kind of seed dormancy in flowering plants. However, for seeds of waterlilies (Nymphaea, Nymphaeaceae), only physiological dormancy (PD) is...
In vitro axenic germination and cultivation of mixotrophic Pyroloideae (Ericaceae)
Pyroloids, forest sub-shrubs of the Ericaceae family, are an important model for their mixotrophic nutrition, which mixes carbon from photosynthesis and from their mycorrhizal fungi. They have medical uses but are...
Photoinhibition of seed germination in Lilioids
The results show the relative importance of the different factors that may be involved in explaining the occurrence of photoinhibition in Lilioid monocots.

Amborella trichopoda helps reveal features of the first flowering plants
It's difficult to peer into the past to see the first flowering plant, but Charlie Scutt shows how an ancestor in the modern-era provides some clues as to what it looked like.

Seed dormancy of the first flowering plants
Dormancy mechanisms act to optimise the timing of seed germination for many seed plants. Fogliani et al. demonstrate that the New-Caledonian shrub Amborella trichopoda exhibits a type of morphophysiological dormancy in...
