Hybridization within the Rana ridibunda Complex of North Africa

1980

Abstract Cellogel electrophoretic study of the plasma protein pattern, especially the albumin fractions, and microdensitometric determination of erythrocyte nuclear DNA amount in 25 frogs of the Rana ridibunda complex from different localities in Morocco and Algeria allows the conclusion that two different forms of this complex are hybridizing in North Africa, as it is found in the Rana esculenta complex in Europe or in the East Asian green frogs. These forms can be identified by their albumin alleles, but not yet by their morphology. They produce mainly triploid hybrids.

Molecular Evolution and the Phylogenetic Relationships of the African Toad, Bufo danielae PERRET, 1977 (Salientia : Bufonidae)

1980

Abstract Phylogenetic relationships of the African toad Bufo danielae are investigated using a variety of biochemical approaches. Nuclear DNA content was assayed and compared to representatives of three species groups of African Bufo. Cellogel electrophoresis of plasma proteins was performed and patterns of B. danielae compared with those of representatives of the African B. regularis species complex. Finally microcomplement fixation analyses of albumin relationships of B. danielae and African Bufo were carried out. The strengths of the varied approaches for phylogenetic analysis are discussed. B. danielae appears most closely related to B. maculatus and B. pusillus, it being some 5-6 mill…
