Published A detailed map of the microverse: Microbial niches
(via sciencedaily.com) Original source What defines the habitat -- the ecological niche -- of a microorganism? It is a combination of environmental factors such as temperature, moisture, and nutrient content. But the exact contribution of each of these factors is difficult to predict. A research team has redefined microbial niches by determining which microorganisms live together.
Published Absolute zero in the quantum computer
(via sciencedaily.com) Original source Absolute zero cannot be reached -- unless you have an infinite amount of energy or an infinite amount of time. Scientists in Vienna (Austria) studying the connection between thermodynamics and quantum physics have now found out that there is a third option: Infinite complexity. It turns out that reaching absolute zero is in a way equivalent to perfectly erasing information in a quantum computer, for which an infinetly complex quantum computer would be required.
Published Insect decline also occurs in forests
(via sciencedaily.com) Original source The number of insects has been declining for years. This has already been well documented for agricultural areas. In forests, however, temporal trends are mostly studied for insect species that are considered pests. Now, a research team has studied the trends of very many insect species in German forests. Contrary to what the researchers had suspected, the results showed that the majority of the studied species are declining.
Published Warming Arctic draws marine predators northwards
(via sciencedaily.com) Original source Marine predators have expanded their ranges into the Arctic waters over the last twenty years, driven by climate change and associated increases in productivity.
Published Innovative method predicts the effects of climate change on cold-blooded animals
(via sciencedaily.com) In the face of a warming climate that is having a profound effect on global biodiversity and will change the distribution and abundance of many animals, a research team has developed a statistical model that improves estimates of habitat suitability and extinction probability for cold-blooded animals as temperatures climb.
Published Can cities make room for woodpeckers?
(via sciencedaily.com) Original source Researchers are deploying the latest mapping techniques to identify the most important suburban habitat for North America's largest woodpecker. Wildlife habitat in congested places is becoming increasingly fragmented as forests give way to new construction. Eventually, this could spell trouble to an animal with specific habitat needs like the pileated woodpecker.
Published Ants took over the world by following flowering plants out of prehistoric forests
(via sciencedaily.com) Today, ants are pretty much everywhere. To learn more about how these insects conquered the world, scientists used a combination of fossils, DNA, and data on the habitat preferences of modern species to piece together how ants and plants have been evolving together over the past 60 million years. They found that when flowering plants spread out from forests, the ants followed, kicking off the evolution of the thousands of ant species alive today.
Published Can a solid be a superfluid? Engineering a novel supersolid state from layered 2D materials
(via sciencedaily.com) Original source Physicists predict that layered electronic 2D semiconductors can host a curious quantum phase of matter called the supersolid. This counterintuitive quantum material simultaneously forms a rigid crystal, and yet at the same time allows particles to flow without friction, with all the particles belong to the same single quantum state.
Published Detecting coral biodiversity in seawater samples
(via sciencedaily.com) Researchers have developed a method to measure coral biodiversity through extracting the environmental DNA (or eDNA) from a liter of surface seawater collected from above a reef. The method has been confirmed to work through observations made by scientific divers in the same areas of ocean. This has paved the way for large-scale comprehensive surveys of reef-building coral to take place and removes the reliance of direct observations made through scientific scuba diving or snorkeling.
Published Conserving wildlife can help mitigate climate change
(via sciencedaily.com) Solving the climate crisis and biodiversity crisis are not separate issues. Animals remove billions of tons of carbon dioxide each year. Restoring species will help limit global warming, new science reveals.
Published Turtles and crocodiles with unique characteristics are more likely to go extinct
(via sciencedaily.com) New study demonstrates that the most endangered turtles and crocodile species are those that have evolved unique life strategies. Many of the most threatened species carry out important ecosystem functions that other species depend on. Habitat loss was identified as the key overall threat to turtles and crocodiles, followed by climate change and global trade. Unique species faced additional pressure from local consumption, diseases, and pollution.
Published Climate change threatens lemurs on Madagascar
(via sciencedaily.com) Even supposedly adaptable mammal species face increased risk of extinction.
Published Rare beetle, rediscovered after 55 years, named in honor of Jerry Brown
(via sciencedaily.com) While sampling for insects on former California Gov. Jerry Brown's ranch, a University of California, Berkeley, entomologist collected a rare species of beetle that had never been named or described -- and which, according to records, had not been observed by scientists in over 55 years. The new species will be named Bembidion brownorum, in honor of Jerry Brown and his wife, Anne Brown.
Published Global natural history initiative builds groundbreaking database to address 21st century challenges
(via sciencedaily.com) A group of natural history museums has mapped the total collections from 73 of the world's largest natural history museums in 28 countries. This is the first step of an ambitious effort to inventory global holdings that can help scientists and decision makers find solutions to urgent, wide-ranging issues such as climate change, food insecurity, human health, pandemic preparedness, and wildlife conservation.
Published At least 80% of the world's most important sites for biodiversity on land currently contain human developments
(via sciencedaily.com) At least 80% of sites identified as being internationally important for biodiversity on land currently contain infrastructure -- of which more than 75% contain roads. In the future, more sites that are important for biodiversity could contain powerplants, mines and oil and gas infrastructure.
Published Towards reducing biodiversity loss in fragmented habitats
(via sciencedaily.com) By combining lab experiments and mathematical modelling, researchers have found a way to predict the movement of species that could guide conservation efforts to reconnect fragmented habitats.
Published 'Y-ball' compound yields quantum secrets
(via sciencedaily.com) Scientists investigating a compound called 'Y-ball' -- which belongs to a mysterious class of 'strange metals' viewed as centrally important to next-generation quantum materials -- have found new ways to probe and understand its behavior.
Published Large survey for exotic pet owners reveals concern for conservation
(via sciencedaily.com) When exotic species such as parrots, snakes, monkeys, or aquarium fishes are kept as pets, this may lead to unsustainable trade and impact negatively the conservation of these species globally. Understanding what drives demand among keepers may help inform adequate conservation strategies to address unsustainable trade.
Published Surprise in the quantum world: Disorder leads to ferromagnetic topological insulator
(via sciencedaily.com) Magnetic topological insulators are an exotic class of materials that conduct electrons without any resistance at all and so are regarded as a promising breakthrough in materials science. Researchers have achieved a significant milestone in the pursuit of energy-efficient quantum technologies by designing the ferromagnetic topological insulator MnBi6Te10 from the manganese bismuth telluride family. The amazing thing about this quantum material is that its ferromagnetic properties only occur when some atoms swap places, introducing antisite disorder.
Published Going beyond English is critical for conservation
(via sciencedaily.com) Research in languages other than English is critically important for biodiversity conservation and is shockingly under-utilized internationally, according to an international research team.
