What can mathematical modeling teach us about the micrometeorology of the southern Amazonian "transitional" forest? Quite a lot, it turns out. This particular forest is located between the rain forest of the Amazon Basin and the tropical Brazilian Savanna, so it plays a crucial role in both regional and global biogeochemical cycling. Researchers have delved into how the transitional forest ensures a connection between the rain forest and the savanna, as reported in Chaos.
New study offers recommendations for creating landscapes with year-round visual appeal.
A songbird species that flourishes on the salmon-rich side of dams in the western United States struggles when it tries to nest on the side closed off from the fish and the nutrients they leave behind.
The large, fast-moving mudslide that buried much of Oso, Washington in March 2014 was the deadliest landslide in U.S. history. University of Washington geologists analyzed woody debris buried in earlier slides and used radiocarbon dating to map the history of activity at the site.
Geologists investigating an unusual landform in the Wabash River Valley in southern Illinois expected to find seismic origins, but instead found the aftermath of rushing floodwaters from melting Midwestern glaciers after the last ice age. The finding could give clues to how floodwaters may behave as glacier melt increases today in places like Greenland and Iceland.
Oceans cover almost three-quarters of the planet and are major contributors to atmospheric aerosols in the form of sea spray particles. These sea spray aerosols are rich in organic materials that impact cloud formation and the world’s climate. Despite their abundance and significance, sea spray aerosols are not well understood. Researchers in collaboration with EMSL scientists are learning more about the chemistry of sea spray aerosols and their role in cloud formation to better account for them in climate models.

Frank Incropera. former dean of the University of Notre Dame’s College of Engineering, acknowledges that it’s somewhat unusual for an engineer to delve deeply into the topic of climate change. Scientists, not engineers, have played the most prominent roles in the climate change debate to date. However, Incropera believes solving the problem going forward will require a joint effort from the two specialties.
The designation of marine protected areas in the coral reefs of East Africa may not be the only solution to overfishing. A URI scientist says that’s because broad protections like the establishment of no-fishing zones often do not target the species critical for promoting healthy ecosystems.
Estimates of future global temperatures based on recent observations must account for the differing characteristics of each important driver of recent climate change, according to a new NASA study published Dec. 14 in the journal Nature Climate Change.
Scientists from James Cook University have discovered two critically endangered species of sea snakes, previously thought to be extinct, off the coast of Western Australia.

Two types of bacteria found in the soil have enabled scientists at Texas A&M AgriLife Research to get the dirt on how resistance to antibiotics develops along with a separate survival strategy. The study, published in the journal PLoS Genetics this month, identifies an atypical antibiotic molecule and the way in which the resistance to that molecule arises, including the identity of the genes that are responsible, according to Dr. Paul Straight, AgriLife Research biochemist.
Accelerating rates of sea-level rise linked to climate change pose a major threat to coastal marshes and the vital carbon capturing they perform. But a new Duke University study finds marshes may be more resilient than previously believed.
The ARM West Antarctic Radiation Experiment (AWARE) is a long-overdue effort to collect fundamental data in a challenging and remote region where changes in climate have worldwide implications. AWARE principal investigators from Scripps Institution of Oceanography at UC San Diego and Brookhaven National Laboratory, and the Atmospheric Radiation Measurement (ARM) Climate Research Facility technical director, will discuss the field campaign, which launched in November, at a special workshop at the AGU Fall Meeting: 5 p.m. Wednesday, Dec. 16 at the Fall Meeting Press Conference Room (Room 3000, Moscone West).
There’s more to an ecosystem than the visible plants and animals. The soil underneath is alive with vital microbes. They make sure nutrients from dead plant and animal material are broken down and made useable by other plants. This completes the process of nutrient cycling and carbon storage. Scientists are learning more about how important these microbes are. But how do changes in temperature and precipitation levels affect microbes? And will that affect carbon storage?
By the latter half of this century, toxic algal blooms like the one that cut off drinking water to the city of Toledo in 2014 will no longer be the exception, but the norm, a study suggests. The findings hold implications for hundreds of coastal regions around the world where nutrient runoff and climate change intersect to make toxic algae a problem.
Scientists still have a lot of questions about how much and how quickly sea levels will rise in coming years, says University at Buffalo geologist Beata Csatho. That holds true even if the Paris climate deal's ambitious targets are met.
A study published today finds a surprising and very recent shift away from the steady relationship among species that prevailed for more than 300 million years. The study, published in the journal Nature, offers the first long-term view of how species associated with each other for half of the existence of multicellular life on Earth.
University of Arkansas researchers have simulated the effect of a series of retention ponds in the West Fork of the White River Watershed and found that construction of 22 one-acre ponds, with an average flood-pool depth of 8.2 feet, in sub-basin areas can decrease peak-flow runoff by about 15 percent. Such a retention pond system would have the potential to significantly decrease water loss from runoff in watersheds of at least 75,000 acres.
When you think of wildfires, you may not think of wetlands. But the seldom-seen blazes may help some endangered species, according to a newly published study by a former UF/IFAS researcher. Severe wetland fires -- so rare they occur only a few times per century – also can change vegetation and patterns of water movement.
The ability of baby fish to find a home, or other safe haven, to grow into adulthood will be severely impacted under predicted ocean acidification, University of Adelaide research has found.
On Dec. 3, the legislature for Argentina's Chubut province established a new marine protected area off Punta Tombo, which would help preserve the feeding grounds for about 500,000 Magellanic penguins that make their home along this rocky stretch of Argentine coast.
