A spectrum from slowly diversifying, cohesive species of phototrophs and C1-trophs to quickly diversifying, non-cohesive species of generalist heterotrophs. Where do pathogens fit in?

A Theory-Based Pragmatism for Discovering and Classifying Newly Divergent Species of Bacterial Pathogens - Genetics and Evolution of Infectious Diseases (Second Edition) - 2 Bacterial systematics has integrated an increasing diversity of phenotypic and molecular characteristics into the demarcation of bacterial species. Most species recognized in taxonomy of bacteria are extremely diverse in physiology, genome content, and ecology. This chapter proposes a universal appr...

Much of the carbon stored in soil takes so long to break down and release into the atmosphere that its potential impact on global warming may go unnoticed. But a recent study showed that when soil temperatures increase, so does the ability of soil microbes to break down and release this carbon, creating yet another vicious positive feedback in climate change.
