Agonistic behavior and hierarchical formation of the Przewalski's Horse was conducted from the last ten-day in May to the last ten-day in June, 2007, when a new herd was formed and released into the second reintroduction site in Kalamaili Ungulate Reserve, Xinjiang. Focal sampling and all-occurrence sampling methods were used to observe and record the agonistic behaviors of the herd, and the dominance index of each individual was calculated.

Turtle Island has an abundant marine ecology because of the Black Tide Warm Current which passes northward through here all year long. It is one of the three major fishing areas in Taiwan—primarily shrimps, crabs, squids, octopuses, and branchiostegidae are caught here. The migration of many kinds of fish to this area attracts whales and dolphins. This is a popular whale and dolphin watching spot.

龟山岛位於宜兰外海约10公里处，龟山岛海域有黑潮流经，附近2至3海里海域较浅且平坦，鱼群大多聚集於此，众多的鱼群让龟山岛成为台湾三大渔场之一，以觅食小鱼维生的海豚也就将这里当成它们活动场所，造就宜兰主要的赏鲸豚地点，包括长吻飞旋原海豚，飞旋海豚、热带点斑原海豚、瑞氏海豚、小虎鲸、瓶鼻海豚、侏儒抹香鲸、伪虎鲸和长吻真海豚等17种鲸豚经常在这个海域出没，最佳赏鲸豚季节为每年4月到9月底。
