Researchers attempt to piece together the puzzle of tree species diversity

By | Botany, Forestry, News

Questions about the origin of nature have fascinated humans since the dawn of culture. One phenomenon of particular interest is the high diversity of forests in the tropics, relative to those in the temperate zone. One prominent hypothesis is that the greater stability of tropical forests allows greater prevalence of pests, each of which then can exert greater damage on its favored host tree than in the temperate zone, particularly when the tree species concerned becomes common.

New study: Forests are still underrated as allies to curb rural poverty

By | Climate change, Forestry, Future Directions, News

In the face of the Covid-19 pandemic and the mounting threat of climate change, forests and trees are vital for the rural poor in countries around the world. However, the poor are rarely able to capture the bulk of benefits from forests. A global science assessment analyses how forests can realize their potential to reduce poverty in a fair and lasting manner.

Researchers Discover Novel Molecular Mechanism That Enables Conifers to Adapt to Winter

By | Forestry, News, Scandinavian Plant Physiology Society

Photosynthesis in conifer forests is one of the most important carbon sinks on a global scale. Unlike broadleaf trees, conifers are evergreen and retain their photosynthesis structure throughout the year. Especially in late winter, the combination of freezing temperatures and high light intensity exposes the needles to oxidative damage that could lead to the destruction of molecules and cell structures that contribute to photosynthesis. Researchers have discovered a previously unknown mechanism that enables spruce trees to adapt to winter.

Scientists Reconstruct Spring Hydroclimate on South-central Tibetan Plateau by Living and Dead Alpine Juniper Shrubs

By | Climate change, Forestry, News, Plant Science

Alpine regions on the Tibetan Plateau are sensitive to climate change, however, little is known about their long-term hydroclimate variability due to short instrumental records. A research team established a 537-year standard shrub-ring chronology by cross-dating living and dead Wilson juniper shrubs sampled nearby the Nam Co Lake, on the south-central Tibetan Plateau.
