Reptiles and frogs of the Eastern Highlands and heavy mists and dew as moisture moves inland from the Indian Ocean. Many streams and rivers originate in these mountains, which form the watershed between the Zambezi and Save River systems. 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
Hox genes in amphibians and reptiles anterior-posterior mesoderm of various developing animal models. One conclusion that this varied concentration of protein expression is actually causing differentiation amongst various tissues and could be one of the culprits behind these so-called "gradient fields". While the protein products of Hox genes are strongly involved in these fields and differentiation in amphibians and reptiles, there are other causality factors involved. For example, retinoic acid and other growth factors have been shown to play a role in these gradient fields. Hox genes in amphibians and reptiles Hox genes play a massive role in some amphibians and reptiles in their ability to
