Anaerobic oxidation of methane (AOM) in the marine environment is meditated by three phylogenically distinct clusters of Archaea called ANME-1, 2 and 3 (Anaerobic Methane-Oxidizing Archaea: ANME). ANME-1 and ANME-2 can be distinguished with biomarker composition. Environmental regulation leading to the dominance of ANME-1 or ANME-2 is not clear. <br>In this study the author investigated the lipid biomarker composition of ANME at the selected seep sites with high methane flux to find the clues to potential niche occupation by the different type of ANME groups. Samples were collected from (1) Umitaka spur off Joetsu, (2) Ryuyo canyon off Tokai, (3) Kumanonada mud volcano, (4) Sagami bay off Hatsushima and (5) Kuroshima knoll. ANME-1 markers were detected in the samples from (1), (2) and (3). On the other hand, ANME-2 markers were detected in the samples from (4) and (5). <br>This study will be useful in identifying the environmental factors controlling the ANME community.
