Abstract

Seasonal migration and reproductive behaviour of the Common River Frog (Amietia angolensis) in the North-West University Botanical gardens The study was conducted in the North-West University Botanical Gardens where all 18 ponds provide habitat for the river frogs. Approximately 117 river frogs were marked with pit-tags. Their migration within a pond and throughout the garden as well as their breeding activity was monitored over a period of 12 months. Results regarding migration and activity over seasons showed that frogs are not likely to migrate, only when forced by human intervention. In a certain pond the males have their own territories. The common river frog starts breeding in autumn, declines a little over mid winter and reaches a peak during spring.
