The Andes Mountains in South America are the world's longest mountain range and a hotspot of biodiversity. But the forest that climbs up this mountain range provides another important service to humanity. Andean forests are helping to protect the planet by acting as a carbon sink, absorbing carbon dioxide and keeping some of this climate-altering gas out of circulation, according to new research published in Nature Communications.
Underneath the apparent messiness of forests lurk extraordinary regularities, governed by the biological mechanisms that drive universal forces of growth, death, and competition.
A new publication offers a comprehensive guide to help plant scientists communicate their work to the world. An Iowa State University scientist who contributed to the multi-institutional effort says it's critical that plant scientists emphasize outreach to make sure plant science is able to meet the demands of climate change and population growth.
Research in the Peruvian Andes highlights critical climate threats to montane forests and urges for current conservation plans to take climate projections into account.
When trees die during a drought event, they die of thirst: A field study on spruce trees shows that an abrupt collapse of the hydraulic system is responsible.
Invasive species wreak havoc on ecosystems and economies--but new research published in Conservation Science and Practice finds that the public plays an important role in identifying and alerting authorities to new pests that reach America's shores.
Common ragweed is an annual plant whose allergenic pollen affects human health. It's an invasive species particularly well-adapted to living at roadsides. New research, published in in the open-access, peer-reviewed journal NeoBiota, found high population growth along high-traffic roads even in shaded and less disturbed road sections, suggesting that seed dispersal by vehicles and by road maintenance can compensate, at least partly, for less favorable habitat conditions.
The extent to which the composition of the microbiome of apples and oil pumpkins depends on the geographical location and what insights can be derived from this for breeding, health and shelf life of the fruits is shown in two recent publications by researchers at TU Graz.
The meristem of the gerbera is patterned on the molecular level already at a stage where no primordia or other changes are discernible by even an electron microscope.
Researchers compared lake sediment, tree ring data and archaeological evidence to reconstruct a 1,200 history of fire, climate, and human activity of the Fish Lake Plateau, a high-elevation forest in central Utah in the U.S. They found that Indigenous people used small, frequent fires, a practice known as cultural burning, which reduced the risk for large-scale wildfire activity in mountain environments even during periods of drought more extreme and prolonged than today.
