Community-wide patterns in pollen and ovule production, their ratio (P/O), and other floral traits along an elevation gradient in southwestern China
BackgroundAs the male and female gametophytes of flowering plants, pollen and ovules largely determine the upper and lower boundaries of plant...

Well-hidden forests? Modern pollen spectra from Central Yakutia (Eastern Siberia) contribute to the interpretation of the last glacial vegetation in Central Europe
The landscape of central Europe is thought to have been dominated by steppe, forest-steppe, or tundra during the Last Glacial. This classical view is...
