Samenvatting

The echolocation calls of some species of Microchiropteran bats from the rainforest of Cameroon and Gabon are already described due to research in other countries. A goal of this project is to create a complete list of all known species, their distribution and echolocation calls. Furthermore, attempts are made to describe the echolocation calls for those species of which this is not yet done.

There are relations between morphology, foraging behaviour and echolocation call. In this study these relations are used to estimate the echolocation calls. The next hypotheses are used: species within a family or genus produce a similar type of echolocation call; the frequency of a call is negatively correlated with the bodysize of an individual; the echolocation call can be determined by morphology and foraging behaviour.

The first two hypotheses are supported by the results. Information on the echolocation calls of 19 species is found. Overall 70 species are known to occur in the rainforest of Cameroon and Gabon. It was possible to make an estimation of the echolocation call of 17 species. For 23 species only the type of call could be determined. Whether the estimated echolocation calls are correct, has to be examined with fieldwork.
