Published The underground network: Decoding the dynamics of plant-fungal symbiosis
(via sciencedaily.com) Original source The intricate dance of nature often unfolds in mysterious ways, hidden from the naked eye. At the heart of this enigmatic tango lies a vital partnership: the symbiosis between plants and a type of fungi known as arbuscular mycorrhizal (AM) fungi. New groundbreaking research delves into this partnership, revealing key insights that deepen our understanding of plant-AM fungi interactions and could lead to advances in sustainable agriculture.
Published Unexpected biodiversity on the ocean floor
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source European forests with a greater diversity of tree species are more resilient to storms, according to new research.
Published Global warming has a bigger effect on compact, fast-moving typhoons
(via sciencedaily.com) Original source A group has found that larger, slow-moving typhoons are more likely to be resilient to the effects of global warming. However, more compact, fast-moving storms are more likely to be sensitive. These findings suggest an improved method for projecting the strength of typhoons under global warming conditions.
Published The complexity of forests cannot be explained by simple mathematical rules, study finds
(via sciencedaily.com) Original source The way trees grow together do not resemble how branches grow on a single tree, scientists have discovered.
Published War in Ukraine severely limits ability to track Arctic climate change
(via sciencedaily.com) Original source Scientists no longer have direct access to data from Russian Arctic research stations. Without this data, our view of climate changes in the region is increasingly biased, new research shows.
Published Paper provides a clearer picture of severe hydro hazards
(via sciencedaily.com) Original source A new study now provides a global examination of drought-pluvial volatility -- or the tendency to shift from one weather extreme to another.
Published A large percentage of European plastic sent to Vietnam ends up in nature
(via sciencedaily.com) Original source Despite strict EU regulations on plastic recycling, there is little oversight on plastic waste shipped from the EU to Vietnam. A large percentage of the exported European plastic cannot be recycled and gets dumped in nature, according to recent research.
Published 'Talking' tomatoes: How their communication is influenced by enemies and friends
(via sciencedaily.com) Original source Plants produce a range of chemicals known as volatile organic compounds that influence their interactions with the world around them. In a new study, researchers investigated how the type and amount of these VOCs change based on different features of tomato plants.
Published World's largest database of weeds lets scientists peer into the past, and future, of global agriculture
(via sciencedaily.com) Original source A new database of weeds that can help scientists understand how traditional agricultural systems were managed throughout history, could also provide insights into how global trends like the climate crisis could affect the resilience of our modern day food systems.
Published Study offers rare long-term analysis of techniques for creating standing dead trees for wildlife habitat
(via sciencedaily.com) Original source 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 Marine heat waves trigger shift in hatch dates and early growth of Pacific cod
(via sciencedaily.com) Original source Marine heat waves appear to trigger earlier reproduction, high mortality in early life stages and fewer surviving juvenile Pacific cod in the Gulf of Alaska, a new study shows. These changes in the hatch cycle and early growth patterns persisted in years following the marine heat waves, which could have implications for the future of Gulf of Alaska Pacific cod, an economically and culturally significant species.
Published Innovative tech shows promise to boost rubber production in US
(via sciencedaily.com) Original source With disease and high demand posing threats to the world's primary natural rubber supply in Southeast Asia, scientists are working to ramp up the U.S. rubber market by advancing methods to extract latex from two sustainable North American plant sources: a dandelion species and a desert shrub.
Published Gulls swap natural for urban habitats, machine-learning study finds
(via sciencedaily.com) Original source The study is the first of its kind to compile a three-year dataset using a citizen science-based, opportunistic research method to include a large sample of gulls and other sub-Arctic birds in urban Alaska. The study provides a current snapshot of the habitat shift to an urban landscape.
Published A new perspective on the temperature inside tropical forests
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 Planetary Commons: Fostering global cooperation to safeguard critical Earth system functions
(via sciencedaily.com) Original source Tipping elements of the Earth system should be considered global commons, researchers argue. Global commons cannot -- as they currently do -- only include the parts of the planet outside of national borders, like the high seas or Antarctica. They must also include all the environmental systems that regulate the functioning and state of the planet, namely all systems on Earth we all depend on, irrespective on where in the world we live. This calls for a new level of transnational cooperation, leading experts in legal, social and Earth system sciences say. To limit risks for human societies and secure critical Earth system functions they propose a new framework of planetary commons to guide governance of the planet.
Published Wolves and elk are (mostly) welcome back in Poland and Germany's Oder Delta region, survey shows
(via sciencedaily.com) Original source 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 Ice age could help predict oceans' response to global warming
(via sciencedaily.com) Original source A new way to measure the ocean oxygen level and its connections with carbon dioxide in the Earth's atmosphere during the last ice age could help explain the role oceans played in past glacial melting cycles and improve predictions of how ocean carbon cycles will respond to global warming.
Published A window into plant evolution: The unusual genetic journey of lycophytes
(via sciencedaily.com) Original source An international team of researchers has uncovered a remarkable genetic phenomenon in lycophytes, which are similar to ferns and among the oldest land plants. Their study reveals that these plants have maintained a consistent genetic structure for over 350 million years, a significant deviation from the norm in plant genetics.
