Published Tropical plant species are as threatened by climate change as widely feared, study confirms
(via sciencedaily.com) Original source Biologists who set out to better understand the effects of climate change on plant species in tropical mountain regions found that even small variations in temperature and moisture can have massive impacts, threatening not only plants that live there, but also the ecosystems they support. A study based on labor-intensive fieldwork and analysis in tropical mountain regions shows that a warmer and drier climate will lead to massive losses of plant species.
Published The most endangered fish are the least studied
(via sciencedaily.com) Original source The most threatened reef fishes are also the most overlooked by scientists and the general public. Scientists measured the level of human interest in 2,408 species of marine reef fish and found that the attention of the scientific community is attracted by the commercial value more than the ecological value of the fishes. The public, on the other hand, is primarily influenced by the aesthetic characteristics of certain species, such as the red lionfish (Pterois volitans) and the mandarinfish (Synchiropus splendidus).
Published Reef pest feasts on 'sea sawdust'
(via sciencedaily.com) Original source Researchers have uncovered an under the sea phenomenon where coral-destroying crown-of-thorns starfish larvae have been feasting on blue-green algae bacteria known as 'sea sawdust'.
Published Discovery of a hybrid lineage offers clues to how trees adapt to climate change
(via sciencedaily.com) Original source The discovery of a hybrid population of poplar trees in western Wyoming has provided insight into how natural hybridization informs the evolution of many plant species, according to researchers. They also said their discovery suggests that genetic exchange between species may be critical for adaptation to environmental change.
Published Physicists develop new theory describing the energy landscape formed when quantum particles gather together
(via sciencedaily.com) Original source An international team of physicists has proven new theorems in quantum mechanics that describe the 'energy landscapes' of collections of quantum particles. Their work addresses decades-old questions, opening up new routes to make computer simulation of materials much more accurate. This, in turn, may help scientists design a suite of materials that could revolutionize green technologies.
Published Paving the way to extremely fast, compact computer memory
(via sciencedaily.com) Original source Researchers have demonstrated that the layered multiferroic material nickel iodide (NiI2) may be the best candidate yet for devices such as magnetic computer memory that are extremely fast and compact. Specifically, they found that NiI2 has greater magnetoelectric coupling than any known material of its kind.
Published Logged forests can still have ecological value -- if not pushed too far
(via sciencedaily.com) Original source Researchers have analysed data from 127 studies to reveal 'thresholds' for when logged rainforests lose the ability to sustain themselves. The results could widen the scope of which forests are considered 'worth' conserving, but also show how much logging degrades forests beyond the point of no return.
Published Scientists use machine learning to predict diversity of tree species in forests
(via sciencedaily.com) Original source Researchers used machine learning to generate highly detailed maps of over 100 million individual trees from 24 sites across the U.S. These maps provide information about individual tree species and conditions, which can greatly aid conservation efforts and other ecological projects.
Published Researchers find that frogs can quickly increase their tolerance to pesticides
(via sciencedaily.com) Original source Although there is a large body of research on pests evolving tolerances for the pesticides meant to destroy them, there have been considerably fewer studies on how non-target animals in these ecosystems may do the same.
Published Unlocking the mystery of preexisting drug resistance: New study sheds light on cancer evolution
(via sciencedaily.com) Original source The evolution of resistance to diseases, from infectious illnesses to cancers, poses a formidable challenge. Despite the expectation that resistance-conferring mutations would dwindle in the absence of treatment due to a reduced growth rate, preexisting resistance is pervasive across diseases that evolve -- like cancer and pathogens -- defying conventional wisdom.
Published History shows that humans are good for biodiversity... sometimes
(via sciencedaily.com) Original source Humans have been an important driver of vegetation change over thousands of years, and, in some places, had positive impacts on biodiversity, according to a new study.
Published Loss of oxygen in lakes and oceans a major threat to ecosystems, society, and planet
(via sciencedaily.com) Original source Oxygen is a fundamental requirement of life, and the loss of oxygen in water, referred to as aquatic deoxygenation, is a threat to life at all levels. In fact, researchers describe how ongoing deoxygenation presents a major threat to the stability of the planet as a whole.
Published Study examines urban forests across the United States
(via sciencedaily.com) Original source Tree-planting campaigns have been underway in the United States, especially in cities, as part of climate mitigation efforts given the many environmental benefits of urban forests. But a new study finds that some areas within urban forests in the U.S., may be more capable than trees growing around city home lawns in adapting to a warmer climate.
Published Mapping the world's fungi from air samples
(via sciencedaily.com) Original source Researchers have found that the key to a quick and cost-effective mapping of biodiversity has been right in front of our eyes all along, but at the same time invisible -- i.e., in the air that surrounds us.
Published A breakthrough on the edge: One step closer to topological quantum computing
(via sciencedaily.com) Original source Researchers have achieved a significant breakthrough in quantum materials, potentially setting the stage for advancements in topological superconductivity and robust quantum computing.
Published Moving from the visible to the infrared: Developing high quality nanocrystals
(via sciencedaily.com) Original source Awarded the 2023 Nobel Prize in Chemistry, quantum dots have a wide variety of applications ranging from displays and LED lights to chemical reaction catalysis and bioimaging. These semiconductor nanocrystals are so small -- on the order of nanometers -- that their properties, such as color, are size dependent, and they start to exhibit quantum properties. This technology has been really well developed, but only in the visible spectrum, leaving untapped opportunities for technologies in both the ultraviolet and infrared regions of the electromagnetic spectrum.
Published Global database reveals large gaps in our knowledge of four-footed animals
(via sciencedaily.com) Original source Researchers developed TetrapodTraits -- a global database of animals with four feet -- which can now be applied for better ecology, evolution and conservation research.
Published Whale remains tracked to highlight sustainable disposal benefits
(via sciencedaily.com) Original source A new study highlights the sustainable, cultural and ecosystem benefits of offshore removal or decomposition of whale remains. The study tracked the remains of a humpback whale that was intercepted before washing up on the shoreline, then repositioned 30km offshore and fitted with a satellite tag that tracked its position as it drifted with the wind and currents for 6 days before falling to the seabed.
Published How a plant app helps identify the consequences of climate change
(via sciencedaily.com) Original source A research team has developed an algorithm that analyses observational data from a plant identification app. The novel approach can be used to derive ecological patterns that could provide valuable information about the effects of climate change on plants.
Published 'Sacrifice' of virus data clears the path to open a disease discovery pipeline
(via sciencedaily.com) Original source Tens of millions of still-unknown or misunderstood viruses can cause diseases -- including new pandemics -- and affect the health of valuable terrestrial and marine environments. Now a new pipeline to investigate the 'virosphere,' or all the genomes of viruses and bacteriophages (viruses that attack bacteria) of the world, has been developed by an international collaboration.
