Microbes far beneath the seafloor rely on carbon recycling to survive（图）
Microbes far beneath seafloor rely carbon recycling survive
2020/3/20
Scientists at the Woods Hole Oceanographic Institution have revealed how microorganisms survive in rocks nestled thousands of feet beneath the ocean floor in the lower oceanic crust. The study is publ...
Algae-killing viruses spur nutrient recycling in oceans（图）
Algae-killing viruses nutrient recycling oceans
2019/10/23
Scientists have confirmed that viruses can kill marine algae called diatoms, but diatom die-offs near the ocean surface may provide nutrients and organic matter for recycling by other algae.Diatoms ar...
Less life:Limited phosphorus recycling suppressed early Earth’s biosphere
Less life Limited phosphorus recycling early Earth’s biosphere
2017/12/18
As Earth’s oxygen levels rose to near-modern levels over the last 800 million years, phosphorus levels also increased, according to modeling led by the UW’s Michael Kipp and others. Accordingly, Kipp ...
Coral reefs—the world’s most productive and diverse marine ecosystems—rely on a masterful recycling program to stay healthy. The corals and algae that form the base of the reef’s food web release a va...
Hypoxic events stimulate nitrogen recycling in a shallow salt-wedge estuary: The Yarra River estuary, Australia
Hypoxic events stimulate nitrogen recycling shallow salt-wedge estuary The Yarra River estuary Australia
2014/4/4
The Yarra River estuary is a salt-wedge estuary prone to periods of stratification-induced anoxia and hypoxia (O2 < 100 μmol L−1) during low-flow events. Nitrate reduction pathways were examined...
Relative importance of CO2 recycling and CH4 pathways in lake food webs along a dissolved organic carbon gradient
CO2 recycling CH4 pathways lake food webs a dissolved organic carbon gradient
2014/5/4
Terrestrial ecosystems export large quantities of dissolved organic carbon (DOC) to aquatic ecosystems. This DOC can serve as a resource for heterotrophic bacteria and influence whether lakes function...
