Isolation of an autotrophic ammonia-oxidizing marine archaeon
The isolation of a marine crenarchaeote that grows chemolithoautotrophically by aerobically oxidizing ammonia to nitrite—the first observation of nitrification in the Archaea is reported, suggesting that nitrifying marine Cren archaeota may be important to global carbon and nitrogen cycles. Expand
Ammonia oxidation kinetics determine niche separation of nitrifying Archaea and Bacteria
Oligotrophic ammonia oxidation kinetics and cellular characteristics of the mesophilic crenarchaeon ‘Candidatus Nitrosopumilus maritimus’ strain SCM1 support the hypothesis that nitrification is more prevalent in the marine nitrogen cycle than accounted for in current biogeochemical models. Expand
Ammonia availability shapes the seasonal distribution and activity of archaeal and bacterial ammonia oxidizers in the Puget Sound Estuary
Observations offer additional ecological support for the idea that niche separation of AOA and AOB is in part determined by ammonia concentrations in estuarine ecosystems. Expand
Stress in wild-caught Eurasian otters ( Lutra lutra ): effects of a long-acting neuroleptic and time in captivity
It is suggested that, when captive conditions are adequate, keeping wild-caught animals in human care for a period of time prior to their release into the wild can be beneficial, however, further studies taking into account other welfare indicators would be useful. Expand

Genomic analysis of the symbiotic marine crenarchaeon, Cenarchaeumsymbiosum
The genome sequence of C. symbiosum reflects a unique and unusual evolutionary, physiological, and ecological history, one remarkably distinct from that of any other previously known microbial lineage. Expand
Inhibition of ammonia oxidation in the thermophilic ammonia-oxidizing archaeon Nitrosocaldus yellowstonii (617.6)
Molecular data suggests ammonia-oxidizing archaea (AOA) play an important role in nitrogen cycling. In particular, organisms related to the thermophilic archaeon Nitrosocaldus yellowstonii appear toExpand
