Orientation and navigation in Bufo bufo: a quest for repeatability of arena experiments

Pancreatic endocrine cells in Bufo bufo: immunocytochemistry and ultrastructure.

The endocrine pancreas of the toad consists of rounded islets of various sizes embedded in the exocrine tissue. Isolated cells are also present. At least 4 types of endocrine cell are distinguishable by shape, size and electrondensity of the secretory granules as well as by their immunoreactivity with different antisera: insulin, somatostatin, pancreatic polypeptide, and glucagon cells. Insulin...

Morphological and Morphometric Variations of Erythrocyte in Clarias Gariepinus, Bufo Bufo and Agama Agama Using Some Histological Stains

Introduction: Erythrocytes are highly specialized and the most abundant cell type in vertebrates’ blood. Their main function is the transportation of oxygen to tissues of the body via hemoglobin. Methods: The study was aimed at evaluating erythrocyte morphology in Clarias gariepinus (Cg), Bufo bufo (Bb), and Agama agama (Aa) using different stains; Also, morphometric analysis of erythrocyte w...

Analysis of survival probabilities of female common toads, Bufo bufo

How complex is the Bufo bufo species group?

Species delineation remains one of the most challenging tasks in the study of biodiversity, mostly owing to the application of different species concepts, which results in contrasting taxonomic arrangements. This has important practical consequences, since species are basic units in fields like ecology and conservation biology. We here review molecular genetic evidence relevant to the systemati...
