Microorganisms are vital in mediating the earth's biogeochemical cycles; yet, despite our rapidly increasing ability to explore complex environmental microbial communities, the relationship between microbial community structure and ecosystem processes remains poorly understood. Here, we address a fundamental and unanswered question in microbial ecology:(More)
Many of the challenges facing children now are a function of changing times, including increase in urbanization, political violence, changing family forms, and in some areas decreased supplies of adequate food. This review focuses particularly on those changes in which children are the victims and which induce new threats for them, rather than on problems(More)
The ecological mechanisms driving community succession are widely debated, particularly for microorganisms. While successional soil microbial communities are known to undergo predictable changes in structure concomitant with shifts in a variety of edaphic properties, the causal mechanisms underlying these patterns are poorly understood. Thus, to(More)
