  • Massive organism is crashing on our watch
    on October 17, 2018 at 6:10 pm

    Researchers have conducted the first complete assessment of the Pando aspen clone and the results show continuing deterioration of this 'forest of one tree.' While a portion of the famed grove is recovery nicely as a result of previous restoration, the majority of Pando (Latin for 'I Spread') is diminishing by attrition. […]

  • Can forests save us from climate change?
    on October 16, 2018 at 3:01 pm

    Additional climate benefits through sustainable forest management will be modest and local rather than global. Even if Europe's forests are managed in such a way that their carbon sequestration is maximized it will not impact the climate significantly. […]

  • Forest carbon stocks have been overestimated for 50 years
    on October 16, 2018 at 3:01 pm

    A formula used to calculate basic wood density has recently been corrected. Basic density is widely used to compute carbon storage by trees. Researchers estimate that the error in the initial formula resulted in an overestimation of forest carbon stocks, to the tune of almost 5 percent. […]

  • Why tropical forests are so ecologically diverse
    on October 15, 2018 at 8:42 pm

    The population of a tropical tree increases mostly in places where it is rare, a new study found. […]

  • Tropical moths in the mountains are larger
    on October 12, 2018 at 3:01 pm

    Researchers have measured more than 19,000 tropical moths from 1,100 species to find out whether their size varies with elevation. The researchers found clear patterns: moths increase in size significantly at higher elevations. […]

  • Carbon emissions from Amazonian forest fires up to 4 times worse than feared
    on October 8, 2018 at 12:35 pm

    Carbon losses caused by El Niño forest fires of 2015 and 2016 could be up to four times greater than thought. […]

  • Amazon rainforest conservation victories spill losses to neighbors
    on October 4, 2018 at 6:40 pm

    New research suggests that protecting the Amazon rainforest from deforestation may just be shifting the damage to a less renowned neighbor. The unintended consequences are profound. […]

  • Species-rich forests store twice as much carbon as monocultures
    on October 4, 2018 at 6:39 pm

    Species-rich subtropical forests can take up on average twice as much carbon as monocultures. An international research team has evaluated data from forests grown specifically for this purpose in China with a total of over 150,000 trees. The results speak in favor of using many different tree species during reforestation. […]

  • Primary tropical forests are best but regrowing forests are also vital to biodiversity
    on October 4, 2018 at 12:53 pm

    Even after 40 years of recovery, secondary forests remain species and carbon-poor compared to undisturbed primary forests, a new study reveals. However these secondary forests -- forests regrowing in previously deforested areas -- are still vitally important to biodiversity conservation and carbon storage, argue scientists. […]

  • Lilly Pilly fossils reveal snowless Snowy Mountains
    on October 3, 2018 at 2:27 pm

    Leaf fossils discovered high in Australia's Snowy Mountains have revealed a past history of warmer rainforest vegetation and a lack of snow, in contrast with the alpine vegetation and winter snow-covered slopes of today. […]

  • City-dwelling blue tits may lay bigger eggs because of what they eat
    on October 3, 2018 at 1:03 pm

    Blue tit eggs that were laid in urban parkland were 5% larger than eggs laid in a nearby forest, which could be due to differences in the amount of calcium available to birds in urban and forest environments, a study finds. […]

  • Secondary forests have short lifespans
    on October 2, 2018 at 2:29 pm

    Secondary forests only last an average of 20 years. The finding presents a major problem for large-scale restoration policy, which often focuses on commitments to restore a certain number of hectares by a given year. But the benefits of restoration depend on those forests persisting. It takes much longer than 20 years for a secondary forest to absorb large amounts of carbon, or to provide habitat for many forest species, research shows. […]

  • Invasive plants can boost blue carbon storage
    on October 1, 2018 at 12:21 pm

    When invasive species enter the picture, things are rarely black and white. A new article has revealed that some plant invaders could help fight climate change by making it easier for ecosystems to store 'blue carbon' -- the carbon stored in coastal environments like salt marshes, mangroves and seagrasses. But other invaders, most notably animals, can do the exact opposite. […]

  • Amazon mangroves store twice as much carbon per acre as region's famous rainforest
    on September 27, 2018 at 6:53 pm

    Scientists have determined for the first time that Amazon's waterlogged coastal mangrove forests, which are being clear cut for cattle pastures and shrimp ponds, store significantly more carbon per acre than the region's famous rainforest. […]

  • Once majestic Atlantic Forest 'empty' after 500 years of over-exploitation
    on September 25, 2018 at 6:04 pm

    New research finds that 500 years of over-exploitation has halved mammal populations in South America's once majestic Atlantic Forest. A new analysis of mammal populations reveals the devastating effects of human disturbance since the area was first colonized in the 1500s. They found that apex predators and large carnivores, such as jaguars and pumas, as well as large-bodied herbivores, such as tapirs, were among the groups whose numbers had suffered the most. […]

  • Land-based bird populations are at risk of local extinction
    on September 21, 2018 at 12:32 am

    A new report finds that land-based bird populations are becoming confined to nature reserves in some parts of the world -- raising the risk of global extinction -- due to the loss of suitable habitat. […]

  • Improving 'silvopastures' for bird conservation
    on September 19, 2018 at 5:39 pm

    The adoption of 'silvopastures' -- incorporating trees into pastureland -- can provide habitat for forest bird species and improve connectivity in landscapes fragmented by agriculture. But how do silvopastures measure up to natural forest habitat? New research shows that birds in silvopasture forage less efficiently than those in forest fragments but offers suggestions for how silvopasture habitat could be improved. […]

  • Newly identified African bird species already in trouble
    on September 19, 2018 at 5:39 pm

    Central Africa's Albertine Rift region is a biodiversity hotspot consisting of a system of highlands that spans six countries. Recent studies have shown that the population of sooty bush-shrikes occupying the region's mid-elevation forests is a distinct species, and new research reveals that this newly discovered species may already be endangered due to pressure from agricultural development. […]

  • Diverse forests are stronger against drought
    on September 19, 2018 at 5:30 pm

    Researchers report that forests with trees that employ a high diversity of traits related to water use suffer less of an impact from drought. The results, which expand on previous work that looked at individual tree species' resilience based on hydraulic traits, lead to new research directions on forest resilience and inform forest managers working to rebuild forests after logging or wildfire. […]

  • Jararaca pit vipers: Giant' specimens proliferation linked to fewer predators
    on September 18, 2018 at 7:48 pm

    In São Paulo, Brazil, it is the lesser presence of predators, not large food supply, that can explain why an isolated green area concentrates more giant pit vipers than a wide forest reserve. […]

  • Climate change may drive 10 percent of amphibian species in the Atlantic Rainforest to extinction
    on September 13, 2018 at 12:24 am

    Climate conditions forecast for 2050 and 2070 will be potentially lethal to species less adapted to climate variation, according to Brazilian researchers. […]

  • Europe's renewable energy directive poised to harm global forests, experts argue
    on September 12, 2018 at 12:12 pm

    Europe's decision to promote the use of wood as a 'renewable fuel' will likely greatly increase Europe's greenhouse gas emissions and cause severe harm to the world's forests, according to a new paper. […]

  • End of Colombia conflict may bring new threats to ecosystems
    on September 12, 2018 at 12:12 pm

    The end of a 52-year internal conflict could spell trouble for the second most biodiverse country in the world. A new study outlines a sustainable path forward. […]

  • Birds retreating from climate change, deforestation in Honduras cloud forests
    on September 6, 2018 at 10:42 pm

    Cloud forests are not immune to very down-to-earth problems of climate change and deforestation. A 10-year study of bird populations in Cusuco National Park, Honduras, shows that the peak of bird diversity in this mountainous park is moving higher in elevation. Additional land protection, unfortunately, may not be enough to reverse the trend, driven in part by globally rising temperatures. […]

  • Tree species distributions in Amazonia modeled
    on September 6, 2018 at 2:04 pm

    Researchers have succeeded in producing distribution maps for a selection of important tropical tree species in Peruvian lowland Amazonia. This was achieved by using machine learning methods that combine satellite imagery and field data. The study shows that it is possible to model tree species distributions at a spatial resolution that is fine enough to facilitate the practical management of forest resources. […]

  • Coastal strip in Brazil sheds new light on early farming
    on September 5, 2018 at 3:23 am

    Humans may have been cultivating plants on a narrow coastal strip in Brazil as far back as 4,800 years ago, according to a new study. […]

  • California: Global warming, El Niño could cause wetter winters, drier conditions in other months
    on September 4, 2018 at 7:04 pm

    New research indicates that what future precipitation California gets will be pretty much limited to the winter months -- think deluge-type rainfall rather than snow -- and non-winter months will be even dryer than usual, with little or no rain at all. […]

  • An ocean apart, carnivorous pitcher plants create similar communities
    on August 29, 2018 at 3:56 pm

    Asian pitchers transplanted to Massachusetts bogs can mimic the living communities of natives so well that the pitcher plant mosquito -- a specialized insect that evolved to complete its life cycle exclusively in North American pitchers -- lays eggs in the impostors, new research shows. […]

  • For carbon storage, biodiversity can help -- or hurt
    on August 27, 2018 at 10:07 pm

    Biodiversity plays a significant role in forest carbon storage, but surprisingly less than previously thought, new research suggests. […]

  • Tree species richness in Amazonian wetlands is three times greater than expected
    on August 24, 2018 at 2:11 pm

    Compilation of data from forest inventories and botanical collections generates a list of 3,615 tree species in wetland areas of the Amazon Basin. […]
