Researchers at Wits University in Johannesburg, South Africa, have created the world's first framework, to better guide the management of terrestrial invasive species.
Scientists have solved a puzzle that has long baffled botanists -- why some plants on high mountainsides are hairy while their low-lying cousins are bald.
Over the past three millennia, selective breeding has dramatically widened the array of plant domestication traits. However, a close look at the archaeobotanical record illustrates a similar suite of linked traits emerging before humans began selectively breeding food crops. In the current study, Spengler summarizes all of these early evolutionary responses in plants, arguing that these shared traits evolved in response to human seed-dispersal services.
Public health agencies worldwide have identified antibiotic resistance of disease-causing bacteria as one of humanity's most critical challenges. However, scientists haven't discovered a new class of antibiotics in more than 30 years. Now, researchers reporting in ACS Infectious Diseases have uncovered the hidden antibiotic potential of a non-psychoactive cannabis compound called cannabigerol (CBG), which helped control methicillin-resistant Staphylococcus aureus (MRSA) infections in mice.
Plants obtain their energy from the sun. Other beings rely on eating to survive. Yet how does the energy flow inside ecosystems function and are there differences between ecosystems with many species in comparison to those with few species? Researchers have now examined these questions using a holistic approach by evaluating data gathered through a large-scale biodiversity experiment.
New research on sand dunes in China describes how even neighboring dunes can long remain in different and seemingly conflicting states -- confounding the assessment of stabilization efforts and masking the effects of climate change.
As nations prepare to mitigate climate change, decision makers need to understand how land use fits into the climate equation. A new study looked at land use changes over two decades and found a major shift from cropland to forests. That change made western Europe cooler.
A new study published in the Ecological Society of America's journal Ecological Applications examines how warming and increased precipitation (rain and snow) harms the seeds in the ground of the Tibetan Plateau and elsewhere.
Species adapt to their local climates, but how often they adapt to their local communities remains a mystery. To find answers, researchers at McGill University and the University of British Columbia examined over 125 studies testing local adaptation in over 100 species of plants and animals in an article published in The American Naturalist.
A remarkable new treasure has been found by scientists from the University of Portsmouth -- the first fossil plant gum on record. The beautiful, amber-like material has been discovered in 110-million-year-old fossilized leaves. University of Portsmouth Ph.D. student Emily Roberts, made the discovery while examining fossilized leaves of the Welwitschiophyllum plant, found in the Crato Formation, Brazil. Emily noticed thin amber-colored bands locked inside some of the fossilized leaves she was studying.
