Using radio transmitters, scientists have gained new insights into the behavior of medium ground finches in the Galapagos Islands. A study reveals daily movement patterns covering an area equivalent to the size of 30 soccer fields.
Bizarre meat-eating dinosaur joins ‘Rogues’ Gallery’ of giant predators from classic fossil site in Egypt’s Sahara Desert
The fossil of a still-unnamed species provides the first known record of the abelisaurid group of theropods from a middle Cretaceous-aged (approximately 98 million years old) rock unit known as the Bahariya Formation, which is exposed in the Bahariya Oasis of the Western Desert of Egypt.
Updating our understanding of Earth’s architecture
New models that show how the continents were assembled are providing fresh insights into the history of the Earth and will help provide a better understanding of natural hazards like earthquakes and volcanoes.
Amazon River freshwater fish show signs of overexploitation
As the cherished rainforest in South America's Amazon River region continues to shrink, the river itself now presents evidence of other dangers: the overexploitation of freshwater fish.
Climate change and human exploitation to blame for historic decline in Atlantic Salmon
Research has revealed that an abrupt change in climate conditions in the North Atlantic around 800 years ago played a role in a decline in Atlantic salmon populations returning to rivers. Subsequent human exploitation of salmon combined to reduce their populations still further.
Otters learn from each other — but solve some puzzles alone
Otters learn skills from each other -- but they also solve some mysteries alone, new research shows.
Tiny conservation heroes: Wild cherry blossoms could save forest landscapes
Researchers have found that symbolic species could be used for the conservation and community-based management of traditional forest landscapes. The team studied how different social groups within a local community valued wild cherry trees, a symbolic species important for connecting people with nature in Japan. The results indicated that differences...
Dirty Work: Researcher Examines Workers’ Exposure to Toxic Chemicals During Deepwater Horizon Cleanup
For 87 days in 2010, roughly 200 million gallons of crude oil spewed from the Deepwater Horizon oil rig, 50 miles off the coast of Louisiana in the Gulf of Mexico.
Carbon Dioxide Now More Than 50% Higher Than Pre-Industrial Levels
Carbon dioxide measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory peaked for 2022 at 421 parts per million in May, pushing the atmosphere further into territory not seen for millions of years, scientists from NOAA and Scripps Institution of Oceanography offsite link at the University of California San Diego announced...
Models Predict That Planned Phosphorus Reductions Will Make Lake Erie More Toxic
Reducing levels of the nutrient phosphorus to control harmful algal blooms in places like Lake Erie is actually advantageous to toxic cyanobacteria strains, which can lead to an increase in toxins in the water, according to a new modeling study.
