Many bacteria exhibit the remarkable ability to thrive on a diverse range of nutritional substrates. This allows them to survive in environments with a complex composition of resources, even if their total availability is low. The optimal regulation …
In this work, we introduce a novel method for compound identification in mixtures based on nuclear magnetic resonance spectra. Contrary to many other methods, our approach can be used without peak-picking the mixture spectrum and simultaneously …
A distinguishing feature of many ecological networks in the microbial realm is the diversity of substrates that could potentially serve as energy sources for microbial consumers. The microorganisms are themselves the agents of compound …
Marine dissolved organic matter (DOM) contains more carbon than the combined stocks of Earth’s biota. Organisms in the ocean continuously release a myriad of molecules that become food for microheterotrophs, but, for unknown reasons, a residual …
The rise of the World Airline Network over the past century has led to sharp changes in our notions of “distance” and “closeness”—in terms of both trade and travel, but also (less desirably) with respect to the spread of disease. When novel pathogens …
Dissolved organic carbon (DOC) forms one of the largest active organic carbon reservoirs on Earth and reaches average radiocarbon ages of several thousand years. Many previous large scale DOC models assume different lability classes (labile to …
