How did Africa's grasslands get started?

Between 10 million and 6 million years ago, vegetation across much of the world underwent a transformation, as warmth-adapted grasses displaced previously dominant plants, shrubs and trees. The new grasses carried out the ...

Study shows how plants evolve for faster growth

Scientists at the University of Sheffield have taken a step forward in understanding how evolution has changed the photosynthesis process in wild plants to help them grow more rapidly.

Explaining the history of Australia's vegetation

University of Adelaide-led research has uncovered the history of when and why the native vegetation that today dominates much of Australia first expanded across the continent.

Will rising carbon dioxide levels really boost plant growth?

Plants have become an unlikely subject of political debate. Many projections suggest that burning fossil fuels and the resulting climate change will make it harder to grow enough food for everyone in the coming decades. But ...
