Cycad plants provide an important 'ecosystem service'

A study published in the June 2020 edition of the peer-reviewed journal Horticulturae shows that cycads, which are in decline and among the world's most threatened group of plants, provide an important service to their neighboring ...

Plant roots increase carbon emission from permafrost soils

A key uncertainty in climate projections is the amount of carbon emitted by thawing permafrost in the Arctic. Plant roots in soil stimulate microbial decomposition, a mechanism called the priming effect. An international ...

NASA's Perseverance rover will scour Mars for signs of life

NASA's most advanced Mars rover, Perseverance, launches from Earth on July 30, on a mission to seek out signs of ancient microbial life on what was once a river delta three-and-a-half billion years ago.

Carbon cycling in wet soils

Under changing, increasingly dynamic climatic conditions, temperate soils are forecast to experience a high degree of variability in moisture conditions due to periods of drought and/or flood. These periodic shifts between ...

Study finds warming peat may boost greenhouse gases

Warming temperatures in cold-climate peatlands may over time trigger decomposition of old, deeply buried peat and increase emissions of climate-harming methane and carbon dioxide into the air, according to a study led by ...
