Scientists from the Cornell Lab of Ornithology and Colorado State University used observations from the Lab’s eBird citizen-science program to estimate the seasonal species richness of nocturnally migrating passerines within 333 well surveyed urban areas in the contiguous U.S. “Richness” is defined as the number of different species in an area.
For the first time, honey bees (Apis cerana) have been documented using tools, specifically animal dung, to defend their colonies in Asia. To defend themselves against giant hornet (Vespa soror) attacks, which can wipe out whole colonies, honey bees forage for animal feces and apply spots of it around their nest entrances. Giant hornets were repelled by feces-covered entrances, limiting their ability to mount deadly group attacks.
New research reveals significant changes to the circulation of the North Pacific and its impact on the initial migration of humans from Asia to North America. It provides a new picture of the circulation and climate of the North Pacific at the end of the last ice age, with implications for early human migration.
The New York Power Authority is partnering with the Cornell University Climate Smart Solutions Program to deliver a comprehensive training program to its more than 1,800 employees in New York.
The European Research Council (ERC) will fund groundbreaking research led by IIASA World Population Program Deputy Director Raya Muttarak, which will comprehensively address the impacts of climate change on population dynamics.
Antarctica’s next deep ice core, a 1.5-mile core reaching back to 130,000-year-old ice, will be carried out by a multi-institutional U.S. team led by UW’s Eric Steig. The site hundreds of miles from today’s coastline could provide clues to the most recent collapse of the West Antarctic Ice Sheet.
A new study shows that strong and rapid action to cut emissions of carbon dioxide and other greenhouse gases will help to slow down the rate of global warming over the next twenty years.
The recovery of beavers may have beneficial consequences for amphibians because beaver dams can create the unique habitats that amphibians need.
UC San Diego-led research is providing new details about honey bees and their defenses against preying hornets. Using a common iPad, James Nieh and his colleagues conducted the first study that demonstrates that a contagious warning signal counters fake news in social insects.
Irvine, Calif., Dec. 7, 2020 — In 2018, California wildfires caused economic losses of nearly $150 billion, or about 0.7 percent of the gross domestic product of the entire United States that year, and a considerable fraction of those costs affected people far from the fires and even outside of the Golden State. For a study published today in Nature Sustainability, researchers at the University of California, Irvine, China’s Tsinghua University and other institutions combined physical, epidemiological and economic models to gain a more comprehensive understanding of the impact of the blazes.
UIC’s Energy Resources Center, UIC-ERC, will receive $1.8 million over a 3 year period, beginning in 2021.
WCS will hold a media briefing to demonstrate a new groundbreaking, publicly available index that measures ecological integrity for all the world’s forests: the Forest Landscape Integrity Index.
Using active acoustic telemetry and sonar data, a study provides the first detailed documentation of a shallow water fish diving 450 feet deep to spawn. Prior research has shown that bonefish dive about 164 feet to spawn, but this new and unprecedented study reveals that they reached depths of 450 feet, and moved below 325 feet for two hours before spawning in a rush upward to 220 feet deep.
Researchers from the Niels Bohr Institute, University of Copenhagen have, in collaboration with Norwegian researchers in the ERC Synergy project, ICE2ICE, shown that abrupt climate change occurred as a result of widespread decrease of sea ice.
The findings of a new report suggest that integrated strategies across food production, biodiversity, climate, and diets can meet the objectives of the Paris Agreement and the Sustainable Development Goals (SDGs).
A team led by scientists at the University of Washington and the University of California, San Diego has discovered that cowpeas — a type of bean plant — harbor receptors on the surface of their cells that can detect a compound in caterpillar saliva and initiate anti-herbivore defenses.
A small group of volcanic islands in Alaska's Aleutian chain might be part of a single, undiscovered giant volcano, say scientists presenting the findings Monday, 7 December at AGU's Fall Meeting 2020.
Global Temperature Report: November 2020
Scientists using a unique combination of capabilities at the Advanced Photon Source have learned more about how meteorites affect one of the most abundant materials in the Earth’s crust.
