Genomics provides evidence of glacial refugia in Scandinavia

Evolutionary research on a grass-like, flowering perennial called the northern single-spike sedge has offered some of the first proof of ice-free locations, or glacial refugia, in Northern Europe during Earth's most recent ...

What a Virginia wildflower can tell us about climate change

When climates change, plants and animals often are forced to colonize new areas—or possibly go extinct. Because the climate is currently changing, biologists are keenly interested in predicting how climate-induced migrations ...

It'll be hard, but we can feed the world with plant protein

A U.N. report released last week found a quarter of the world's carbon emissions come from the food chain, particularly meat farming. This has prompted calls to sharply reduce emissions from agriculture and to feed the world ...

Study raises concerns about prevalent orchid viruses

In a Plants, People, Planet study, researchers investigated the evolution of the two most prevalent orchid viruses using information representing their global distribution. The study revealed that considerable international ...

Megadrought caused mega biodiversity loss

Researchers at CSIRO, Australia's national science agency, have painstakingly reconstructed the nation's 'once in a century drought' in the early 1900s, revealing that it caused mass ecosystem collapse and dramatic declines ...

The chemical language of plants depends on context

A team of scientists from the Max Planck Institute for Chemical Ecology in Jena, Germany, studied the ecological function of linalool, a naturally abundant volatile organic compound, in wild Nicotiana attenuata tobacco plants. ...
