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 Building a roadmap to bioengineer plants that produce their own nitrogen fertilizer
(via sciencedaily.com) Original source Nitrogen fertilizers make it possible to feed the world's growing population, but they are also costly adn harm ecosystems. However, a few plants have evolved the ability to acquire their own nitrogen with the help of bacteria, and a new study helps explain how they did it, not once, but multiple times.
Published Wildfire smoke has a silver lining: It can help protect vulnerable tree seedlings
(via sciencedaily.com) Original source Forest scientists studying tree regeneration have found that wildfire smoke comes with an unexpected benefit: It has a cooling capacity that can make life easier for vulnerable seedlings.
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 How domestic rabbits become feral in the wild
(via sciencedaily.com) Original source After sequencing the genomes of nearly 300 rabbits from Europe, South America, and Oceania, researchers found that all of them had a mix of feral and domestic DNA. They say this was not what they had expected to find.
Published Insight into one of life's earliest ancestors revealed in new study
(via sciencedaily.com) Original source Researchers have shed light on Earth's earliest ecosystem, showing that within a few hundred million years of planetary formation, life on Earth was already flourishing.
Published How plant cold specialists can adapt to the environment
(via sciencedaily.com) Original source Evolutionary biologists studied spoonworts to determine what influence genome duplication has on the adaptive potential of plants. The results show that polyploids -- species with more than two sets of chromosomes -- can have an accumulation of structural mutations with signals for a possible local adaptation, enabling them to occupy ecological niches time and time again.
Published Forest carbon storage has declined across much of the Western U.S., likely due to drought and fire
(via sciencedaily.com) Original source Forests have been embraced as a natural climate solution, due to their ability to soak up carbon dioxide from the atmosphere as they grow, locking it up in their trunks, branches, leaves, and roots. But a new study confirms widespread doubts about the potential for most forests in the Western US to help curb climate change. The paper analyzed trends in carbon storage across the American West from 2005 to 2019.
Published Introducing co-cultures: When co-habiting animal species share culture
(via sciencedaily.com) Original source Cooperative hunting, resource sharing, and using the same signals to communicate the same information -- these are all examples of cultural sharing that have been observed between distinct animal species. In a new article, researchers introduce the term 'co-culture' to describe cultural sharing between animal species. These relationships are mutual and go beyond one species watching and mimicking another species' behavior -- in co-cultures, both species influence each other in substantial ways.
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 Planted mangroves' ability to store carbon
(via sciencedaily.com) Original source Ecologists have published new findings on how planted mangroves can store up to 70% of carbon stock to that found in intact stands after only 20 years.
Published Mozambican Woodlands could store more than double the carbon previously estimated
(via sciencedaily.com) Original source The capacity of Mozambican woodlands to capture and store carbon is underestimated and potentially undervalued for their protection and restoration, finds new research from an international team of scientists.
Published Not so simple: Mosses and ferns offer new hope for crop protection
(via sciencedaily.com) Original source Mosses, liverworts, ferns and algae may offer an exciting new research frontier in the global challenge of protecting crops from the threat of disease.
Published Wolves' return has had only small impact on deer populations in NE Washington
(via sciencedaily.com) Original source Wolves returned to Washington state in 2008. A new study shows that, despite their rising numbers, wolves are not having much of an impact on white-tailed deer, one of their primary prey. Scientists report that the biggest factor shaping white-tailed deer populations in northeast Washington is the quality of habitat available, which is largely determined by human activity. Cougars were second in their impact. Wolves were a distant third.
Published Study examines tree adaptability to climate change
(via sciencedaily.com) Original source Many trees could expand their ranges by more than 25 percent based on their potential temperature tolerances.
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 First local extinction in the US due to sea level rise, study suggests
(via sciencedaily.com) Original source The United States has lost its only stand of the massive Key Largo tree cactus in what researchers believe is the first local extinction of a species caused by sea level rise in the country.
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.
