Reptiles and frogs of the Eastern Highlands Reptiles and frogs of the Eastern Highlands The reptiles and frogs of the Eastern Highlands of Zimbabwe and Mozambique mark a biodiversity hotspot for herpetofauna. Diverse frog and reptile communities include endemic species. The Eastern Highlands extend 300 kilometres (190 mi) along Zimbabwe's eastern border with Mozambique. There are two broadly defined high-altitude ecological habitats in the Eastern Zimbabwe montane forest-grassland mosaic; a wet lowland forest ecology predominates the eastern side of the mountain ranges, while a more arid ecology dominates the western side. The Highlands have a more equable climate than Zimbabwe's central plateau, with higher rainfall, low cloud

More broadly, the aim of a clinical trial is to determine what treatments, delivered in what circumstances, to which patients, in what conditions, are the most effective. Therefore, the use of placebos is a standard control component of most clinical trials, which attempt to make some sort of quantitative assessment of the efficacy of medicinal drugs or treatments. Such a test or clinical trial is called a "placebo-controlled" study, and its control is of the negative type. A
