Abstract
Summary Lake Fundudzi is a unique, small inland lake in the north eastern region of South Africa, formed by a landslide. The considerable sedimentation of its basin indicates an age in the order of 10 000s of years. It forms the focus of a rich heritage of ceremonial rituals and myths amongst the local Vhavenda population, but has not enjoyed the protection it deserves and serious impacts have been made by human transformation of the catchment, over-utilization of natural resources, forestry, water abstraction and degradation of the rivers. Additionally, the present fish community is not natural as all larger fish species seem to have been introduced. Some limnological information on this lake has been sporadically collected over a period of 60 years. It indicates conductivities ranging between 2,8 −18,8 μ S m−1 neutral to acid waters and oxygen stratification near the bottom during winter. Zooplankton was characterised by small copepods and rotifers. The lake is presently threatened by an increased anthr...
Fundudzi湖是南非东北部地区一个独特的小内陆湖,由山体滑坡形成。其盆地的大量沉积表明其年龄在一万年左右。它是瓦文达当地居民丰富的仪式和神话遗产的焦点,但没有得到应有的保护,人类对集水区的改造、自然资源的过度利用、林业、水的抽取和河流的退化造成了严重的影响。此外,目前的鱼类群落不是天然的,因为所有较大的鱼类似乎都已被引入。关于这个湖的一些湖泊学资料是在60年的时间里零星收集到的。它表明在冬季,电导率在2、8−18和8 μ S m−1之间,为中性至酸性水,靠近底部有氧分层。浮游动物以小型桡足类和轮虫为特征。这个湖目前正受到越来越多的病害的威胁。
