A new study led by Russ Van Horn, Ph.D., takes the most detailed look yet at the dens of this species. Van Horn, a population sustainability scientist, leads San Diego Zoo Wildlife Alliance's Andean bear conservation program. He was joined by colleagues from the University of British Columbia's Department of Forest and Conservation Sciences and the Spectacled Bear Conservation Society. The study's findings may aid conservation planners in locating den sites or guiding management for suitable bear habitat.
University of California scientists have discovered genetic data that will help food crops like tomatoes and rice survive longer, more intense periods of drought on our warming planet.
Indigenous subsistence of the Bears Ears region modified the landscape, leaving ecological legacies that persist today. A blend of Indigenous knowledge and western science can be used to build management plans for effective stewardship of the region's botanical and cultural resources.
A new open-access research collection published in Ecosphere reveals unexpected lessons drawn from decades of rich data from the Long Term Ecological Research (LTER) Network.
Intact rainforests across tropical Africa continued to remove carbon from the atmosphere before and during the 2015-2016 El Niño, despite the extreme heat and drought. Theyl removed 1.1 billion tonnes of carbon dioxide per year from the atmosphere during the El Niño monitoring period. This rate is equivalent to three times the carbon dioxide emissions of the UK in 2019. Scientists were surprised by this discovery.
Plant diseases don't stop at a nation's borders and miles of oceans don't prevent their spread, either. That's why plant disease surveillance, improved plant disease detection systems and predictive plant disease modeling - integrated at the global scale - are necessary to mitigate future plant disease outbreaks and protect the global food supply,
Next-generation sequencing technology has made it easier than ever for quick diagnosis of plant diseases. "It's really exciting to see how sequencing technologies have evolved and how this new technology facilitates sequencing of entire genomes in such a short amount of time," said Yazmín Rivera, a plant pathologist with the United States Department of Agriculture's Plant Protection and Quarantine program, who recently published a research paper on the efficacy of Oxford Nanopore Technologies protocols.
Cyanobacteria first evolved to perform photosynthesis about 2.4 billion years ago, pumping tons of oxygen into the atmosphere - a period known as the Great Oxygenation Event - which enabled the evolution of multicellular life forms. Led by BTI faculty member Fay-Wei Li, researchers have discovered a new species of cyanobacteria, Anthocerotibacter panamensis, which could help illuminate how photosynthesis evolved to create the world as we know it.
Scientists from China have sequenced and analyzed the genome of lavender to provide insights into what causes its distinct aroma. Their findings shed light into the evolution of this uniquely fragrant plant, which could pave the way for creating improved lavender varieties besides adding to existing knowledge on the evolution, phytochemistry, and ecology of Lamiaceae, the plant family to which lavender belongs.
A plant cell wall's unique ability to expand without weakening or breaking is due to the movement of its cellulose skeleton, according to new research that models the cell wall. The new study, by Penn State researchers, presents a new concept of the plant cell wall, gives insights into plant cell growth, and could provide inspiration for the design of polymeric materials.
