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 ...
Energy Transfer Through Food Webs at Hydrothermal Vents:Linking the Lithosphere to the Biosphere
Energy Transfer Food Webs Hydrothermal Vents Lithosphere Biosphere
2015/7/14
Tectonic and volcanic processes that drive hydrothermal fluid flow and influence its chemistry also regulate the transfer of energy to hydrothermal vent ecosystems. Chemoautotrophic bacteria use the c...

Studying hydrothermal systems by examining the seafloor alone only offers a two-dimensional view of a three-dimensional system. Although technologically challenging, accessing the subsurface to direct...
Production-respiration relationships at different timescales within the Biosphere 2 coral reef biome
Production-respiration different timescales Biosphere 2 coral reef biome
2014/6/10
Temporal relationships between organic carbon production and respiration are not well understood in coral reef ecosystems. We monitored dissolved oxygen (O2) concentrations within the Biosphere 2 cora...
