Tree rings hold clues about ancient solar storms. New research shows tree growth and carbon storage can shift those signals across years.

MADISON – For more than a century, biologists have been working to assign plants, animals and microbes their respective places on the tree of life. More recently, by comparing DNA sequences from a few ...

Forests worldwide may be entering a new phase marked by fewer specialized tree species and more fast-growing generalists.

Scientists have long relied on tree rings to learn about ancient solar storms—rare bursts of high-energy particles from the sun that can disrupt satellites, power grids, and communication systems ...

Tree thinking is a pedagogical approach that emphasises the interpretation and construction of phylogenetic trees to elucidate evolutionary relationships. In the context of evolutionary biology ...

Scientists have discovered a completely new branch on the tree of life. This “supergroup” contains an incredibly diverse range of predatory microbes that are extremely different genetically from any ...

I recently participated in the Minnesota Shade Tree Short Course, which is a two-day professional development conference for tree care professionals sponsored by the University of Minnesota. More than ...
