Distribution patterns of amphibians from the Kakamega forest, Kenya
We discuss generalized geographical range patterns for the 24 anuran species that occur in the Kakamega Forest, western Kenya. Eight distributions are distinguished: from "western Equatorial Rift Valley" to almost entire sub-Saharan. The former may be more common than previously assumed, because some species displaying this geographical range pattern were only recently identified out of species complexes with large distributions. In contrast, continuous distributions of species over the Congo basin may be less common than currently understood.
The stream-dwelling larva of the Ruwenzori River Frog, Amietia ruwenzorica, its buccal cavity and pathology of chytridiomycosis
Tadpoles of Amietia ruwenzorica (Pyxicephalidae, Cacosterninae) were collected in the Ruwenzori Mountains, Uganda(identified by DNA barcoding). The ventrally directed enlarged oral disc with a high number of labial tooth rows (LTRF9(4)/9(1)) and the narrow tail with robust caudal musculature characterise them as stream-dwellers. We name this mor-photype the 'common or standard type of stream-adaptation', because special additional adhesive organs are missing in A.ruwenzorica. The uniserially arranged oral teeth of the spoon-shaped type with 16 to 18 cusps per tooth are known fromother anuran larvae, especially from pyxicephalids. The buccal morphology resembles generalized tadpoles with som…
