Warm Water Causes Aquatic Animals to Suffer from Fatal Respiratory Distress

Until now, the link between rising water temperatures and higher mortality rates in aquatic animals was a bit of a chicken-and-egg situation.

Increased Levels of Dissolved Salts can be Toxic to Aquatic Invertebrates

Aquatic life can suffer when high concentrations of dissolved salts enter freshwater ecosystems, a process known as salinization.

Scientists Discover Genetic Diversity Enhances Productivity Yields of Switchgrass

Going down in history we find that even before farmers could settle down in the Midwestern United States and plant crops, there existed the root systems of prairie grasses, including strong-stemmed and tall switchgrass species that improved the quality of the soil, thus developing millions of acres of top-quality farmland.

High Concentration of CO2 in Soil Can Change Community of Organisms Living in Soil

A high concentration of carbon dioxide gas in the soil can change the community of organisms living in the soil in the long term. At the same time it changes processes in this ecosystem like the subterranean carbon cycle and carbon storage.

Plants and Decomposing Material in Soil Emit More CO2 than Fossil Fuels

In the concrete jungle at the core of a city, carbon dioxide (CO2) emissions are dominated by the fossil fuels burned by the dense concentrations of cars and buildings.

Shipwrecks could be Used to Monitor Health of Deep-Ocean Ecosystems

The 2010 Deepwater Horizon oil spill significantly altered microbial communities thriving near shipwrecks in the Gulf of Mexico, potentially changing these diverse ecosystems and degrading the historically and culturally significant ships they live on, according to new research being presented here. The findings are also revealing how decades-old, or even centuries-old, shipwrecks could be used to monitor the health of deep-ocean ecosystems, and the effects of oil and gas activity in the Gulf, according to the researchers.

Tundra Soil Study Shows Vulnerability of Permafrost Ecosystem Carbon to Climate Warming

Findings from one of the first comprehensive field studies by a collaborative team of researchers demonstrate the active layer microbiome of tundra soil was significantly altered after only 1.5 years of experimental warming—a rapid response demonstrating high sensitivity of this ecosystem to warming. Collectively, the results of this study suggest the vulnerability of permafrost ecosystem carbon to climate warming and the significance of microbial feedbacks in mediating this vulnerability.
