    on September 13, 2017 at 11:24 pm

    Bristlecone pine and limber pine trees in the Great Basin region of the western United States are like two very gnarled, old men in a slow-motion race up the mountaintop, and climate change is the starting gun, according to a new study. The study shows that the tree line has been steadily moving upslope over the past 50 years in the Great Basin. […]

  • Forest regeneration experiment of 30 years yields results
    on September 12, 2017 at 5:48 pm

    A spruce forest regeneration experiment in Interior Alaska that spanned nearly 30 years demonstrates which forest management practices produce the best results. It looked at different combinations of ground treatments to reduce competition from other vegetation and of regeneration methods, such as planting spruce seedlings and broadcast seeding. The results show the environmental and management situations in which different techniques work best and the situations in which they are unnecessary. Results support the state's current reforestation practices. […]

    on August 30, 2017 at 5:22 pm

    New research has shown that there are significant differences between the Asian and the African forest elephant -- and it isn't just about size and the shape of their ears. It is about what they eat and how they affect forest ecosystems. […]

  • High-tech electronics made from autumn leaves
    on August 29, 2017 at 3:38 pm

    Northern China's roadsides are peppered with deciduous phoenix trees, producing an abundance of fallen leaves in autumn. These leaves are generally burned in the colder season, exacerbating the country's air pollution problem. Investigators in Shandong, China, recently discovered a new method to convert this organic waste matter into a porous carbon material that can be used to produce high-tech electronics. […]

    on August 28, 2017 at 4:33 pm

    Considered at risk of extinction, hermit beetles need to be efficiently monitored. However, due to their life cycle, standard sampling is unreasonably time-consuming and quite damaging to both the species and their habitat. In searching for a solution, scientists suggested that trained dogs might be more successful. […]

  • Climate may quickly drive forest-eating beetles north, says study
    on August 28, 2017 at 4:33 pm

    Over the next few decades, global warming-related rises in winter temperatures could significantly extend the range of the southern pine beetle, one of the world's most aggressive tree-killing insects, through much of the northern United States and southern Canada, says a new study. […]

  • Clear it, but will they come? Native plants need re-seeding after rhododendron removal, study finds
    on August 23, 2017 at 1:38 pm

    Native plants need a helping hand if they are to recover from invasive rhododendron, Scottish ecologists have discovered. A new study in the reveals that – even at sites cleared of rhododendron 30 years ago – much native flora has still not returned. As a result, rhododendron eradication programs may need to be supplemented by reseeding for the original plant community to re-establish. […]

  • Using barcodes to trace cell development
    on August 16, 2017 at 5:46 pm

    There are various concepts about how blood cells develop. However, they are based almost exclusively on experiments that solely reflect snapshots. Scientists now present a novel technique that captures the process in a dynamic way. Using a 'random generator,' the researchers label hematopoietic stem cells with genetic barcodes that enable them to trace which cell types arise from the stem cell. […]

  • New critically endangered tree species depends on unique habitat found only on Kaua'i
    on August 16, 2017 at 4:23 pm

    A new tree species, endemic to the floristically rich high Hawaiian island Kaua'i, is already assessed as Critically Endangered according to IUCN criteria.

  • Trees and shrubs offer new food crops to diversify the farm
    on August 11, 2017 at 10:54 pm

    What if we could design a landscape that would provide a variety of nutritious foods, high-quality habitat, and ecosystem services, while also delivering a healthy profit to the landowner? According to researchers, it is not only possible, it should be adopted more widely, now. […]

  • The only way is up: Trees help reptiles thrive
    on August 10, 2017 at 2:49 pm

    If graziers leave trees in place on their land, all types of reptiles will benefit, investigators suggest in a new report. […]

  • Climate change: Silver fir beats Norway spruce and European beech
    on August 10, 2017 at 12:21 pm

    Climate change is making Swiss forests warmer and drier. The trees would have to adapt genetically to the rapidly changing climate to continue flourishing at their current growth location. Yet, they are unlikely to do so in such a short period of time – a single tree generation already takes 100 years or longer. Therefore, the question on how well adapted the trees already are today to the future climate will be crucial for the forests' future. […]

  • Salamanders that breed in the fall are less likely to disperse
    on August 9, 2017 at 7:14 pm

    With changing environments, pond-breeding salamanders face increasingly hazardous treks as the space between breeding ponds and their non-breeding habitat widens or is degraded. A study now suggests that a salamander's success may depend more on when it breeds than on the landscape obstacles it might face. Scientists believe that knowing the patterns in which salamanders move back and forth could lead to better forest management and conservation strategies. […]

  • 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. […]

  • Drought-affected trees die from hydraulic failure and carbon starvation
    on August 7, 2017 at 3:15 pm

    Drought-caused tree deaths are produced by a combination of hydraulic failure and carbon starvation, shows new research. The finding, based on a meta-analysis by 62 scientists from across the world, will improve predictive models of how trees die in response to heat, drought, and other climate stresses. […]

  • Afforestation with non-native trees alters island soils
    on August 7, 2017 at 2:40 pm

    A healthy global debate has occurred concerning the benefits of using non-native trees for restoring some aspects of ecosystem function in degraded habitats. In many cases, the stresses associated with establishing seedlings disallow most native tree species from becoming successfully established in harsh planting sites. The tolerant non-native trees enable successes that would otherwise be unachievable. […]
