Metabolism of one carbon (C1) and methylated compounds in SAR11 bacteria

Creator:

Sun, Jing

Abstract:

SAR11 Alphaproteobacteria are the most abundant aerobic chemoheterotrophs in ocean surface waters. Previous studies have indicated SAR11 cells play an important role in marine carbon cycling and consume up to half of some common dissolved organic compounds, such as amino acids. During sequencing of the first SAR11 genome, genes for...

Biogeochemical signals of mountainous forested watersheds' response to disturbance

Creator:

Guerrero-Bolaño Francisco J.

Abstract:

Small mountainous watersheds are disproportionate sources of land-derived particulate organic matter (POM) to long-term sinks like lake bottoms and the ocean. As such, these ecosystems are an essential component of the global carbon cycle. The burial of POM in lacustrine and marine sediments contributes to the drawdown of atmospheric CO2...
