Water and guppy sampling sites. (A) A map of Japan and the archipelago of Ryukyus. (B) A map partially covering the Ruykyus archipelago including Okinawa Island. (C) Sampling sites at the middle to southern area of Okinawa Island. River systems and ponds were shown by blue lines. The water and guppy sampling sites were indicated by reddish orange-edged white dots. IRN, OYM, CHB, SNB, URN, OPC, TMY, and NSZ indicate site names Iri-nuka, Oyama, Chibu, Senbaru, Uranishi, Okinawa Prefectural Plant Protection Center, Tomoyose, and Nishizaki, respectively. IRN is an independent small spring and is not connected to other river systems. The confluence of the downstream of URN and SNB is marine water and thus guppies do not migrate between these two sampling sites. Adobe Illustrator 2021 v25.2.1 was used to draw the figure based on map imagery.
