Fig. 4

Bimonthly spatial use of the Eastern Pacific by archival-tagged striped marlin. Utilization distribution (UD) is represented in false color. UD values of less than 50% signify high use areas. In each panel, monthly climatological surface temperature isotherms at 18.5 (green) and 24 °C (yellow) are contoured. Spatial extents are also shown for 2 ml L−1 dissolved oxygen at 100 m (lavender). For clarity, only isotherms and dissolved oxygen extents from the second month of each period are shown. The number of individuals and positions available are indicated. Management boundaries of the Inter-American Tropical Tuna Commission are outlined by dotted lines
