Summary Methyl‐coenzyme M reductase (MCR) has been originally identified to catalyse the final step of the methanogenesis pathway. About 20 years ago an aerobic me thane‐oxidizing archaea (ANME) were discovered that use MCR enzymes to activate methane. ANME thrive at the thermodynamic limit of life, are slow‐growing, and in most cases form syntrophic consortia with sulfate‐reducing bacteria. Recently, archaea that have the abi...
Summary The anaerobic oxidation of methane (AOM) is mediated by consortia of anaerobic methane‐oxidizing archaea (ANME) and their specific partner bacteria. In thermophilic AOM consortia enriched from Guaymas Basin, members of the ANME‐1 clade are associated with bacteria of the HotSeep‐1 cluster, which likely perform direct electron exchange via nanowires. The partner bacterium was enriched with hydrogen as sole electron dono...
Breeding system, colony and population structure in the weaver ant Oecophylla smaragdinaNARA Subscribed
Weaver ants ( Oecophylla smaragdina ) are dominant ants in open forests from India, Australia, China and Southeast Asia, whose leaf nests are held together with larval silk. The species, together with its sole congener O. longinoda , has been important in research on biological control, communication, territoriality and colony integration. Over most of the range, only one queen has been found per colony, but the occurrence of...
