Published Flowering for naught: 120 years with nothing to show



Flowering for some plants is a yearly occurrence, for others, it is a once-in-a-lifetime event. A widespread species of bamboo in Japan, Phyllostachys nigra var. henonis, takes this one-time flowering event and pushes it to the extreme: they flower once every 120 years before dying to make way for the next generation. Researchers have realized there might be another issue at hand with this monocarpic species, which is the lack of germination of the seeds from a majority of the flowering specimens. Implications of a once dense field of bamboo, something that serves both as a food source and a source of material for crafts, turning to grassland for several years until the regeneration of bamboo begins to start somehow, can impact the ecology of the area in addition to the country's economy.
Published A global observatory to monitor Earth's biodiversity



At a time of unparalleled rates of biodiversity loss, a new interconnected system to monitor biodiversity around the world is needed to guide action quickly enough to target conservation efforts to where they are most needed.
Published The search for the super potato



As climate change continues to pose severe challenges to ensuring sustainable food supplies around the world, scientists are looking for ways to improve the resilience and nutritional quality of potatoes. Scientists have assembled the genome sequences of nearly 300 varieties of potatoes and its wild relatives to develop more nutritious, disease-free, and weather-proof crop. A team has now created a potato super pangenome to identify genetic traits that can help produce the next super spud.
Published Coastal fisheries show surprising resilience to marine heat waves


New research found that marine heat waves -- prolonged periods of unusually warm ocean temperatures -- haven't had a lasting effect on the fish communities that feed most of the world. The finding is in stark contrast to the devastating effects seen on other marine ecosystems cataloged by scientists after similar periods of warming, including widespread coral bleaching and harmful algal blooms.
Published Emphasizing the need for energy independence could change the views of climate deniers, study says



Emphasising the need for energy independence and environmental stewardship could help to change people’s minds about the climate crisis, a new study says.
Published Unveiling global warming's impact on daily precipitation with deep learning



A research team has conclusively demonstrated that global warming stands as primary driver behind the recent increase in heavy rainfall and heatwaves using deep learning convolutional neural network.
Published Can this forest survive? Predicting forest death or recovery after drought



New work could help forest managers predict which forests are most at risk from drought and which will survive.
Published Climate extremes hit stressed economies even harder



Economies already under stress respond more strongly to weather events like heat waves, river floods and tropical cyclones, a new study shows. A global economic crisis as during the Covid-19 pandemic strongly amplifies the price increases private households experience from the impacts of weather extremes, a team of researchers finds. The price impacts tripled in China, doubled in the United States and increased by a third in the European Union.
Published Male crested macaques more likely to respond to offspring screams recruiting support



When infants are involved in agonistic conflicts, male crested macaques (Macaca nigra) are more likely to respond to screams from their own offspring. This is the conclusion of a recent study led by behavioral ecologists. The researchers studied the behavior of crested macaques in the Tangkoko Nature Reserve on Sulawesi, Indonesia, over a 24-month period (2008 to 2010).
Published Extreme weather events linked to increased child marriage



Among the negative impacts of extreme weather events around the world is one that most people may not think of: an increase in child marriages.
Published Broken by bison, aspen saplings having a tough time in northern Yellowstone


In northern Yellowstone National Park, saplings of quaking aspen, an ecologically important tree in the American West, are being broken by a historically large bison herd, affecting the comeback of aspen from decades of over-browsing by elk.
Published Researchers take aim at weather forecasters' biggest blindspot



Anyone who's been caught in an unexpected downpour knows that weather forecasting is an imperfect science. Now, researchers are taking aim at one of meteorologists' biggest blind spots: extremely short-term forecasts, or nowcasts, that predict what will happen in a given location over the next few minutes.
Published New study reveals anti-cancer properties in Kencur ginger



Scientists have verified the anticancer effects of Kencur, a tropical plant of the ginger family, mainly grown in Southeast Asia, in cell and animal experiments. They found that Kencur extract and its main active components significantly inhibit cancer cell growth at the cellular and animal levels. Furthermore, the involvement of TFAM in the mechanism of action was confirmed.
Published Soils forming on the branches of trees are an overlooked forest habitat


A study on 'canopy soils' on old trees in Costa Rica shows they are important habitats and carbon stores that cannot easily be replaced.
Published National parks support wildlife inside and outside their borders


Fresh research suggests that national parks enhance bird diversity inside their borders. Large parks also support higher diversity of both birds and mammals in nearby unprotected areas.
Published New modeling method helps to explain extreme heat waves



To prepare for extreme heat waves around the world -- particularly in places known for cool summers -- climate-simulation models that include a new computing concept may save tens of thousands of lives.
Published Ice-free preservation method holds promise to protect reefs


An interdisciplinary team of researchers demonstrated that coral can be preserved through a new technique called isochoric vitrification. This process takes the selected coral fragments through the stages of cryopreservation and subsequent revival.
Published Deforestation limits nesting habitat for cavity-nesting birds


A new study of cavity-nesting birds in Ecuador shows the influence of deforestation on their habitat and reproductive success. Nest boxes could help.
Published Researchers unearth a new process by which algae pass on nurtrients to their coral host


Researchers have identified a new pathway by which sugar is released by symbiotic algae. This pathway involves the largely overlooked cell wall, showing that this structure not only protects the cell but plays an important role in symbiosis and carbon circulation in the ocean.
Published Tree mortality in the Black Forest on the rise -- climate change a key driver



Climate impacts such as dry, hot summers reduce the growth and increase the mortality of trees in the Black Forest because they negatively influence the climatic water balance, i.e., the difference between precipitation and potential evapotranspiration. That is the central finding of a long-term study of the influence of climate and climate change on trees in the Black Forest.
