Our understanding of the players and pathways of the global nitrogen cycle has advanced
substantially over recent years with discoveries of several new groups of organisms and …

The microbial nitrogen cycle is one of the most complex and environmentally important
element cycles on Earth and has long been thought to be mediated exclusively by …

The oceans are losing oxygen (O 2), and oxygen minimum zones are expanding due to
climate warming (lower O 2 solubility) and eutrophication related to agriculture. This trend is …

Sediment cores were collected from three sites (1000–1200 m water depth) in the
northeastern Gulf of Mexico from December 2010 to June 2011 to assess changes in …

Until recently, the process of denitrification (conversion of nitrate or nitrite to gaseous
products) was thought to be performed exclusively by prokaryotes and fungi. The finding that …

The present study investigates the influence of seagrass root systems on benthic hard-
shelled meiofauna (foraminifera). In February and July 2011, sediment cores were collected …

Oxygen and nitrate availabilities impact the marine nitrogen cycle at a range of spatial and
temporal scales. Here, we demonstrate the impact of denitrifying foraminifera on the nitrogen …

The negative consequences of fossil fuel burning for the oceans will likely include warming,
acidification and deoxygenation, yet predicting future deoxygenation is difficult. Sensitive …

Anoxia was successfully induced in four benthic chambers installed at 24 m depth on the
northern Adriatic seafloor from 9 days to 10 months. To accurately determine whether …

Live (Rose Bengal stained) benthic foraminifera from the Murray Ridge, within and below
the northern Arabian Sea oxygen minimum zone (OMZ), were studied in order to determine …
