Phys.org / Why prescribed fire often fails: Scorched invasive shrubs can resprout instead of die

Invasive woody plants present a major ecological challenge in eastern U.S. forests by outcompeting native species and spreading quickly, forming dense thickets that crowd out native plants and disrupt ecosystems. Land managers ...

Phys.org / Heat index maps uncover when city greening cools most—and when it can backfire

Tree shade is one of the fastest ways to make heat more bearable. It cuts direct sunlight, protects people walking or working outdoors, and remains essential for heat action plans. A new study by researchers from the Indian ...

Phys.org / Brazilian microfossils interpreted as animal traces are actually algae and bacteria, research reveals

A reexamination of microfossils found in the Brazilian state of Mato Grosso do Sul shows that the marks previously interpreted as traces of worms or other small oceanic animals are actually communities of fossilized microscopic ...
