However, the political mass movement turns human into coral, which could achieve synchronized orgasm in mass scale. The slogans shouted by the people are like the sperm and eggs ejaculated by the coral.

Farmland green treefrog belonging to the family Rhacophoridae is endemic to Taiwan. The mating system of Rhacophorus arvalis is lek. From April 2003 to June 2004 at Yunling in central Taiwan, I investigated the lekking behavior and daily activity pattern, and analyzed the ecological factors on habitat to understand the lek preference in male frogs.

诸罗树蛙属於树蛙科为台湾特有种两栖类，其配对系统属於典型的群集展示系统。2003年4月至2004年6月间，研究者在云林县斗南镇观察记录本种树蛙的群集展示行为及日活动模式，并分析栖地的生态因子，以了解雄蛙对於展示场地选择之偏好。
