| Polyacrylamide gel electrophoresis (PAGE) for basic proteins may be a useful tool for the characterization of whole snake venoms and for the taxonomic classification of snakes of the Elapidae and Viperidae families. However, due to the close proximity of molecular weights among toxins bearing different net charges, sodium dodecyl sulfate (SDS) - PAGE was not able to provide an efficient differentiation. This article reports the electrophoretic analysis of several venoms from the genera Micrurus, Bothrops, Bothriopsis, Crotalus and Lachesis and shows a typical and distinctive electrophoretic profile for each species, with intraspecific and geographic variations. Even in cases in which extreme morphological similarities were present, such as between B.... |

| Several aspects of the ecology of Jameson’s green mamba Dendroaspis jamesoni jamesoni (Traill, 1843), a large-sized arboreal elapid snake, are studied in southern Nigeria. This species 18 common and widespread in the region studied. On the basis of the analysis of both the habitats of capture of the various specimens and the results of a logistical regression model, it seems that this species inhabits a wide variety of habitats (including secondary forest patches and the plantation-forest mosaic), and that its local distribution is not influenced by the Presence of any macrohabitat parameter. Green mambas were observed both in the dry and in the wet season, without any statistical bias toward a particular season. Adult sex-ratio was aPproximately 1 : 1.... |
