  • First winged mammals from the Jurassic period discovered
    on August 9, 2017 at 6:03 pm

    Two 160-million-year-old mammal fossils discovered in China show that the forerunners of mammals in the Jurassic Period evolved to glide and live in trees. With long limbs, long hand and foot fingers, and wing-like membranes for tree-to-tree gliding, Maiopatagium furculiferum and Vilevolodon diplomylos are the oldest known gliders in the long history of early mammals. […]

  • Incomplete drought recovery may be the new normal
    on August 9, 2017 at 6:02 pm

    The amount of time it takes for an ecosystem to recover from a drought is an important measure of a drought's severity. During the 20th century, the total area of land affected by drought increased, and longer recovery times became more common, according to new research published by Nature by a group of scientists including Carnegie's Anna Michalak and Yuanyuan Fang. […]

  • Climate change may confuse plant dormancy cycles
    on August 8, 2017 at 12:51 pm

    Perennial plants in the Midwest are well attuned to their surroundings. They hunker down all winter in a dormant state, just waiting for a sign that it’s safe to unfurl their first tender leaves or flower buds. For many plants, the cue is a sustained warming trend, but day length also factors into the dormancy equation. […]

  • Light pollution as a new threat to pollination
    on August 2, 2017 at 7:39 pm

    Artificial light disrupts nocturnal pollination and leads to a reduced number of fruits produced by the plant. This loss of night time pollination cannot be compensated by diurnal pollinators. The negative impact of artificial light at night on nocturnal pollinators might even propagate further to the diurnal community, as ecologists were able to show. […]

  • What flowers looked like 100 million years ago
    on August 2, 2017 at 1:28 pm

    Flowering plants with at least 300,000 species are by far the most diverse group of plants on Earth. They include almost all the species used by people for food, medicine, and many other purposes. However, flowering plants arose only about 140 million years ago, quite late in the evolution of plants, toward the end of the age of the dinosaurs, but since then have diversified spectacularly. No one knows exactly how this happened, and the origin and early evolution of flowering plants and especially their flowers still remains one of the biggest enigmas in biology, almost 140 years after Charles Darwin called their rapid rise in the Cretaceous "an abominable mystery". […]

  • Corpse flower set for first outdoor bloom
    on July 27, 2017 at 2:53 pm

  • Symbiosis: Butter for my honey
    on July 25, 2017 at 2:06 pm

    Textbooks tell us that, in arbuscular mycorrhizal symbioses, the host plant supplies its fungal symbionts solely with sugars, in return for inorganic nutrients. New findings now show that lipids are also on the menu. […]

  • Better plant carbon-cycle models
    on July 24, 2017 at 3:41 pm

    In the summer of 2012, two undergraduate students tackled a problem that plant ecology experts had overlooked for 30 years. The students demonstrated that different plant species vary in how they take in carbon dioxide and emit water through the pores in their leaves. The data boosted the accuracy of mathematical models of carbon and water fluxes through plant leaves by 30 to 60 percent. […]

  • Hitting the bull's eye on crop nutrient requirements
    on July 19, 2017 at 2:05 pm

    A new method can determine crop nitrogen requirements with a precision of 10-20 kg N/ha by preparing a reference curve to determine when a crop is deficient in nitrogen. The reference curve is based on comparisons of data on leaf area with data on leaf reflectance at different light wavelengths. […]

  • Parasitic worms may lead to agricultural stem cell breakthrough
    on July 19, 2017 at 1:21 pm

    A plant parasitic nematode is a pest that parasitizes the roots of agricultural crops and creates nests called 'galls' which deprive plants of nutrition. Research on plant reactions to parasitic worms shows that parasitism activates plant stem cells which grow to form galls on their roots. This finding is expected to improve crop breeds and alleviate nematode damage, which is estimated to cost hundreds of billions of dollars each year worldwide. […]
