Emissions from coal-fired power plants in China are fertilizing the North Pacific Ocean with a metal nutrient important for marine life, according to new findings from a USC-led research team. The researchers believe these metals could change the ocean ecosystem, though it's unclear whether it would be for better or worse.
Research led by Micaela Pedrazas, who earned her masters at The University of Texas at Austin Jackson School of Geosciences working with Professor Bayani Cardenas, has found permafrost to be mostly absent throughout the shallow seafloor along a coastal field site in northeastern Alaska. That means carbon can be released from coastline sources much more easily than previously thought.
UC assistant professor Latonya Jackson conducted experiments with North American freshwater fish called least killifish. She found that fish exposed to estrogen in concentrations of 5 nanograms per liter in controlled lab conditions had fewer males and produced fewer offspring. Scientists have found estrogen at as much as 16 times that concentration in streams adjacent to sewage treatment plants.
A study quantified the size and age of the forests that grow naturally in degraded and abandoned areas, creating 131 benchmark maps for Brazil. The Amazon has the most restored forests and the Atlantic Rainforest biome has the oldest.
A team of leading environmental experts, spearheaded by the University of Nottingham, have warned that the current war on plastic is detracting from the bigger threats to the environment.
A new study of a 14,000-year record, published in Science Advances, shows that seabird poop transformed an entire ecosystem in the Falkland Islands, raising questions about the birds' survival and the potential impact of climate change on sensitive terrestrial-marine ecosystems
This work examines requirements for introducing CAM and alternative water-saving pathways into C3 plants in different environments.
A 14,000-year paleoecological reconstruction of the sub-Antarctic islands led by University of Maine researchers has found that seabird establishment occurred during a period of regional cooling 5,000 years ago. Their populations, in turn, shifted the Falkland Islands ecosystems through the deposit of high concentrations of guano that helped nourish tussac, produce peat and increase the incidence of fire.
A recent work published in Earth's Future by a team of researchers from the Institute of Atmospheric Physics at the Chinese Academy of Sciences has found that the seasonal cycle of precipitation is likely to enhance at stabilized 1.5°C and 2°C warming scenarios.
A "safety net" made up of multiple ambitious and interlinked goals is needed to tackle nature's alarming decline, according to an international team of researchers analyzing the new goals for biodiversity being drafted by the UN's Convention on Biological Diversity (CBD).
