Since the mid-1900s, humans have been exerting an ever-increasing impact on the global nitrogen cycle. Human activities, such as making fertilizers and burning fossil fuels, have significantly ...

New research shows that the large-scale evolution of microbes was mostly complete 2.5 billion years ago, and that included the beginning of the modern aerobic nitrogen cycle.

About Dr. Galbraith Dr. Eric Galbraith– The Ocean’s Nitrogen Cycle As the philosopher-scientist James Lovelock pointed out, the Earth’s biosphere is a lot like a single organism.

Nitrogen is a key element controlling the species composition, diversity, dynamics, and functioning of many terrestrial, freshwater, and marine ecosystems. Many of the original plant species living in ...
