Loss of biodiversity limits toxin degradation

You might not think of microbes when you consider biodiversity, but it turns out that even a moderate loss of less than 5% of soil microbes may compromise some key ecosystem functions and could lead to lower degradation of ...

Bacterial 'ropes' tie down shifting Southwest

Researchers from Arizona State University have discovered that several species of microbes (cyanobacteria), at least one found prominently in the deserts of the Southwest, have evolved the trait of rope-building to lasso ...

Urban bacteria are a diverse group

More than half the world's population lives in urban areas. In the United States, more than 8 in 10 people are urbanites. Urban ecosystems often have less diverse animal and plant life compared to natural areas. But that's ...

Cover crops, compost and carbon

Soil organic matter has long been known to benefit farmers. The carbon in this organic matter acts as a food source for soil microbes, which then provide other nutrients to the crops grown. Microbes, insects and small soil ...

Invasional meltdown in multi-species plant communities

Invasive alien plant species can pose a serious threat to native biodiversity and to human well-being. Identifying the factors that contribute to invasion success is therefore crucial. Previous studies on biological invasions ...

Researchers pin down one source of a potent greenhouse gas

A study of a Lake Erie wetland suggests that scientists have vastly underestimated the number of places methane-producing microbes can survive—and, as a result, today's global climate models may be misjudging the amount ...

Team pioneers new way to survey thawing Arctic

(Phys.org)—In the snow of Alaska, a Stanford-led team of researchers has found a new way to determine if the soil beneath lakes, normally frozen, is thawing as a result of climate change. If so, the lakes could become a ...

Sweet compounds aid water retention in dry soil

Organic material added by plant roots and microbes provides nutritious candy for the soil. Literally. Released cellular sugar fortifies water and nutrient retention, and maintains the porous earth, according to new Cornell ...

Do soils need a low-salt diet?

Doctors often tell their patients to reduce their salt intake as part of a healthy lifestyle. When we start looking at food labels, we may find salt in surprising places—like baked goods, drinks and canned foods.
