The female giant panda's estrus is known to be photoperiod sensitive, triggered by increasing day length. A pair of giant pandas was brought to Singapore in September 2012 and exposed to a constant temperature and photoperiod during the first 2 years. The female did not show any signs of estrus during that period. In November 2014, photoperiod and temperature were manipulated to simulate seasonal changes, to investigate the effects of environmental factors on the sexual behavior of the giant pandas. This paper documents the changes and observations carried out from 2012 to 2016, in the attempt to breed this vulnerable species.
已知雌性大熊猫的发情期对光周期敏感，由白昼时长增加引发。2012年9月，一对大熊猫被带到新加坡，在最初的两年里处于恒定的温度和光周期环境中。在此期间，雌性大熊猫未表现出任何发情迹象。2014年11月，对光周期和温度进行调控以模拟季节变化，旨在研究环境因素对大熊猫性行为的影响。本文记录了2012年至2016年期间为繁育这种濒危物种所进行的变化及观察情况。
