Fig. 4From: Mitochondrial and nuclear genetic analyses of the tropical black-lip rock oyster (Saccostrea echinata) reveals population subdivision and informs sustainable aquaculture developmentMap showing locations from which oysters (Saccostrea echinata) were sampled within the Northern Territory, Australia. Different coloured circle markers indicate two genetic clusters (1) the west cluster (blue circle markers); PRL, Pirlangimpi (11°15′07″S 130°20′53″E); MLK, Milikapiti (11°22′5″S 130°34′21″E); ANR, Anuru Bay (11°43′23″S 133°20′35″E); WGU, Wigu (11°38′49″S 133°25′23″E); and MRN, Mooroongga Island (11°56′06″S 135°02′47″E); and (2) the east cluster (orange circle markers); NHL, Nhulunbuy (12°14′14″S 136°40′30″E); BKD, Bukudal (13°00′40″S 136°37′41″E); and UMB, Umbakumba (13°39′03″S 136°40′45″E). The dominant near-surface current circulation patterns and location of the Arafura Basin (indicated by the lined polygon) are illustrated (adapted from Schiller [56] and Geoscience Australia [57])Back to article page
