Marine sponges and ammonia-oxidizing archaea (AOA) represent one of the earliest animal-microbe symbioses. AOA are considered metabolically constrained chemolithoautotrophs that remove nitrogenous was...

Abstract. Deep oligotrophic lakes hold over 80% of global lake water. In their hypolimnion, ammonia oxidation (the first step of nitrification) and non-pho

Two groups of ammonia-oxidizing archaea drive marine nitrification. Stuehrenberg et al. reveal that their distribution reflects substrate use, with one relying on urea and the other on ammonia to main...

A new study led by Barbara Bayer (CeMESS, University of Vienna) discovered that ammonia-oxidizing microorganisms contribute much less to carbon fixation in the ocean than previously assumed. The study...

Nitrite oxidation, the second step of nitrification, is essential to the global nitrogen cycle. Nitrite-oxidizing bacteria (NOB) are classified into two groups based on the cellular localization of th...

Soil ecosystems form the foundation of planetary health and play a critical role in climate feedback mechanisms. However, they are also vulnerable to the impacts of global change.

The University of Vienna plans to expand the existing Research Data Management services by offering discipline-specific support through a new Data Stewardship program tailored to meet the discipline-s...

Human activities are driving rapid environmental change on a global scale, with pollutants playing a critical role in pushing planetary systems beyond safe limits. These changes have profound conseque...
