| 摘 要： | 报道浙江丽水三岩寺区域4个无尾两栖类物种（中华大蟾蜍、黑眶蟾蜍、虎纹蛙、镇海林蛙）的4例繁殖期非正常抱对现象，包括多重抱对（1只雌性和3只雄性，虎纹蛙）、从腹部抱对（镇海林蛙）、2只雄性抱对（虎纹蛙）、不同物种之间抱对（雄性黑眶蟾蜍和雌性中华大蟾蜍）等。影响非正常抱对的因素可能包括成年性别比例、种群密度、化学信号（性激素）和被抱对个体的行为反应等。无尾两栖类非正常抱对现象为我们研究无尾两栖类的繁殖行为提供有意义的参考。 |

| Abstract: | The present study reports 4 cases of abnormal amplexus in some anuran species(Bufo gargarizans,Bufo melanostictus,Hoplobatrachus rugulosus and Rana zhenhaiensis)from Lishui,Zhejiang Province.We found four different types of abnormal amplexus in these four anuran species: multiple amplexus(one female and three males,H.rugulosus),amplexus from the abdominal side(R.zhenhaiensis),amplexus between two males(H.rugulosus) and amplexus between specimens from different species(male B.melano stictus and female B.gargarizans).The factors that may influence the abnormal amplexus include operational sex ratio,population density,chemical signals(such as sex hormone) and the response of clasped animals,and the cases of abnormal amplexus provide significant reference for our further study of mating behavior in anurans. |
