In Comoe National Park the savanna inhabiting frog Phrynobatrachus francisci (BOULENGER, 1912) changes its habitats during the dry season. While living at ponds in the wet season, it can be traced only at the border of the river in the dry season. There it is only active during nighttime and within a few centimeters from open water. Habitat selection and activity time seem to be results of higher humidity. Analysis of excrements and dissected frogs as well as selected food choise experiments indicate that P. francisci is an opportunistic feeder. Although females have fully developed eggs, at the end of the dry season, reproduction did not occur in the remaining water bodies of river Comoe.

Hemisus marmoratus uses a breeding chamber for eggs and early tadpole stages. As some nests are even made before the beginning of the rainy season, Hemisus-tadpoles are the first tadpoles arriving in the temporary ponds. Thus they have a developmental advantage to tadpoles of other species and to predators. The time tadpoles spend in their nest is variable. So they may be able to react on the not forseeable rainfalls of their savanna habitat. Despite the channel theory of Wager (1986) our observations speak for additional strategies of the tadpoles reaching water. These may be transport by the mother, sliding on wet soil down to water or floating of the breeding chambers. The use of a certain strategy may depend on habitat structure. Beside these reproductive observations we give further data on activity, food and larval development.
