Published Do tree-planting campaigns follow best practices for successful forest restoration?



New research reviewed publicly available information for 99 different organizations that coordinate large-scale tree-planting programs around the globe to see if these organizations seemed to be applying best practices for successful reforestation.
Published Back from the dead: Tropical tree fern repurposes its dead leaves



Plant biologists report that a species of tree fern found only in Panama reanimates its own dead leaf fronds, converting them into root structures that feed the mother plant. The fern, Cyathea rojasiana, reconfigures these 'zombie leaves,' reversing the flow of water to draw nutrients back into the plant.
Published Scientists develop novel method to estimate biodiversity loss in Singapore over the past two centuries



Scientists have employed novel statistical methods to reveal the extent of biodiversity loss in Singapore over the past two centuries. The study paints the most accurate picture to date of the ecological impact of deforestation and urban development in the tropical city-state. From a comprehensive dataset, the study estimated that Singapore has lost 37 per cent of its species.
Published Soap bark discovery offers a sustainability booster for the global vaccine market



A valuable molecule sourced from the soapbark tree and used as a key ingredient in vaccines, has been replicated in an alternative plant host for the first time, opening unprecedented opportunities for the vaccine industry.
Published Use it or lose it: How seagrasses conquered the sea



Seagrasses provide the foundation of one of the most highly biodiverse, yet vulnerable, coastal marine ecosystems globally. They arose in three independent lineages from their freshwater ancestors some 100 million years ago and are the only fully submerged, marine flowering plants. Moving to such a radically different environment is a rare evolutionary event and definitely not easy. How did they do it? New reference quality genomes provide important clues with relevance to their conservation and biotechnological application.
Published Achieving sustainable urban growth on a global scale



An international group of leading scientists call for an urgent change in the governance of urban expansion as the world's cities continue to grow at unprecedented rates.
Published Tiny ant species disrupts lion's hunting behavior



Data gathered through years of observation reveal an innocuous-seeming ant is disrupting an ecosystem in East Africa, illustrating the complex web of interactions among ants, trees, lions, zebras and buffaloes.
Published Unexpected biodiversity on the ocean floor



Hydrothermal vents and manganese nodule fields in the deep oceans contain more biodiversity than expected.
Published Diverse forests are best at standing up to storms



European forests with a greater diversity of tree species are more resilient to storms, according to new research.
Published The complexity of forests cannot be explained by simple mathematical rules, study finds



The way trees grow together do not resemble how branches grow on a single tree, scientists have discovered.
Published Simple steps can cut snakebite deaths



Scientists have called for simple, effective steps to cut the number of people bitten by venomous snakes.
Published Study offers rare long-term analysis of techniques for creating standing dead trees for wildlife habitat



Ecologists have long known that standing dead trees, commonly referred to as snags, are an important habitat element for forest dwellers and act as a driver of biodiversity. They're so important that in some managed forests, snag creation is part of the conservation tool kit -- i.e., crews sometimes convert a percentage of live trees into dead ones through techniques ranging from sawing off their tops to wounding their trunks to injecting them with disease-causing fungi.
Published A new perspective on the temperature inside tropical forests



New worldwide maps of temperatures inside tropical forests show that global warming affect different way in different parts of the forests. Undergrowth level temperature of the tropical forests can be even 4 degrees less than average temperature of the area.
Published Complex green organisms emerged a billion years ago



Of all the organisms that photosynthesize, land plants have the most complex form. How did this morphology emerge? A team of scientists has taken a deep dive into the evolutionary history of morphological complexity in streptophytes, which include land plants and many green algae. Their research allowed them to go back in time to investigate lineages that emerged long before land plants existed.
Published Wolves and elk are (mostly) welcome back in Poland and Germany's Oder Delta region, survey shows



An online survey conducted in Germany and Poland shows that large parts of the participants support the return of large carnivores and herbivores, such as wolves and elk, to the Oder Delta region. Presented with different rewilding scenarios, the majority of survey participants showed a preference for land management that leads to the comeback of nature to the most natural state possible. Locals, on the other hand, showed some reservations.
Published Student discovers 200-million-year-old flying reptile



Gliding winged-reptiles were amongst the ancient crocodile residents of the Mendip Hills in Somerset, England, researchers at the have revealed.
Published Scientists, farmers and managers work together to avoid the decline of the little bustard, an endangered steppe bird



The collaboration between scientists, farmers and managers is crucial to improve the protection of the little bustard, an endangered steppe-land bird in Spain due to human activity. The reduction of natural habitats, the increase in irrigation and the urbanization of the land have led to having less surface areas that guarantee the survival of this vulnerable species.
Published Researchers pump brakes on 'blue acceleration' harming the world ocean



Protecting the world ocean against accelerating damage from human activities could be cheaper and take up less space than previously thought, new research has found.
Published The heat is on: Scientists discover southern Africa's temps will rise past the rhinos' tolerance



Southern Africa contains the vast majority of the world's remaining populations of both black and white rhinoceroses (80% and 92%, respectively). The region's climate is changing rapidly as a result global warming. Traditional conservation efforts aimed at protecting rhinos have focused on poaching, but until now, there has been no analysis of the impact that climate change may have on the animals. A research team has recently reported that, though the area will be affected by both higher temperatures and changing precipitation, the rhinos are more sensitive to rising temperatures, which will quickly increase above the animals' acceptable maximum threshold.
Published Climate change threatens global forest carbon sequestration, study finds



Climate change is causing Western U.S. forests to be less effective carbon sinks, even as it boosts the productivity of forests in the Eastern U.S., according to new research.
