Syferkuil大坝位于北方大学西北8公里处，由一系列8个相互连接的矩形大坝组成，有水泥边和泥底。本文对O.研究的莫桑比克线虫包括降雨量、光周期、坝水温度和坝水pH值等环境因素的作用。环境至少在启动莫桑比克线虫生殖周期的开始方面发挥着重要作用。莫桑比克人。光周期、降雨量和水温的增加以及水pH值的降低是性腺成熟发生的线索。这些变化似乎对雌性性腺发育的影响大于雄性发育。雄性发育似乎依赖于雌性发育，因为它比雌性发育滞后两个月。这一结果暗示了环境线索和生殖的内分泌控制之间的密切相互作用。如果没有刺激生殖所需的适当环境线索，内分泌控制就无法继续。
Syferkuil Dam is situated 8 km NW of the University of the North and comprises a series of eight interconnected rectangular dams, having cement sides and mud bottoms. Aspects of the reproductive physiology of O. mossambicus that were investigated included the role of environmental factors such as rainfall, photoperiod, dam-water temperature and dam water pH. The environment plays an important role in at least initiating the commencement of the reproductive cycle in O. mossambicus. An increase in photoperiod, rainfall and water temperature together with a decrease in water pH are the cues for gonadal maturity to occur. These changes seem to have a greater impact on female gonad development than male development. Male development seems to be dependent on female development in that it lags behind the female by two months.The results imply a close interaction between environmental cues and endocrine control of reproduction. Endocrine control cannot continue without the appropriate environmental cues required to stimulate reproduction.
