Dr. Tanja Stratmann’s project, titled “Nitrogen Cycling in Modern Sponges with Clues About Their Role in Past Oceans” (SPYCLING for short), focuses on marine sponges as representatives of the oldest ...

Nitrogen is one of the primary nutrients critical for the survival of all living organisms. Although nitrogen is very abundant in the atmosphere, it is largely inaccessible in this form to most ...

Nitrogen is essential for all life on Earth. In the global oceans, however, this element is scarce, and nitrogen availability is therefore critical for the growth of marine life. Some bacteria found ...

In the nitrogen cycle, phytoplankton and other marine plants turn nitrate (NO 3) into organic nitrogen during photosynthesis. The organic nitrogen sinks into the deep ocean, where microbes "eat" the ...

As climate change progresses, rising temperatures may impact nitrogen runoff from land to lakes and streams more than projected increases in total and extreme precipitation for most of the continental ...
