Taste buds in the palatal mucosa of snakes
Item type: Journal Article • Journal: African Zoology • Authors: Herman Berkhoudt --- Evolutionary Morphology, The Netherlands Perrin Wilson --- Department of Biology, U.S.A Bruce Young --- Department of Biology, U.S.AAn examination of the oral mucosa of Crotalus and several Scolecophidia revealed the presence of taste buds. The taste buds in these two divergent groups of snakes are similar in appearance, and correspond to previous descriptions of gustatory organs in... -
A dwarf among giants: phylogenetic position of the elusive Angolan Adder (Bitis heraldica) and biogeographic affinities of Angolan Afromontane regions
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Luis MP Ceríaco --- Museu de História Natural e da Ciência da Universidade do Porto, Portugal Krystal A Tolley --- South African National Biodiversity Institute, Kirstenbosch Research Centre, South Africa Mariana P Marques --- Research Center in Biodiversity and Genetic Resources (CIBIO), Research Network in Biodiversity and Evolutionary Biology (InBIO), University of Porto, Portugal Matthew P Heinicke --- Department of Natural Sciences, University of Michigan-Dearborn, USA Aaron M Bauer --- Department of Biology and Center for Biodiversity and Ecosystem Stewardship, Villanova University, USAThe Angolan Adder, Bitis heraldica (Bocage, 1889), is endemic to the Angolan central plateau and is one of the most poorly known and rarely observed species of African snakes. The phylogenetic placement of B. heraldica within the four subgenera of... -

Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Luca Luiselli --- Centre of Environmental Studies “Demetra” and F.I.Z.V., Italy GodfreyC. Akani --- Rivers State University of Science and Technology, NigeriaThe stomach content of 524 Gaboon Vipers, Bitis gabonica gabonica (53 subadults, 222 males and 249 females) and 392 Nose‐horned Vipers, Bitis nasicornis (48 subadults, 163 males and 161 females), from a number of forest‐plantation mosaic areas of southern Nigeria... -
On the identification and distribution of the two‐striped night adder (Causus bilineatus) and related forms
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Jens Bødtker Rasmussen --- University of Copenhagen, DenmarkAn examination of material of Causus bilineatus Boulenger 1905 and of its sympatric congeners from south central Africa confirms its distinctness. Comparisons of allopatric populations of C. bilineatus indicate that the variation in number of ventral and subcaudal scutes is... -
A comprehensive phylogeny of night adders (Causus)
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Krystal A Tolley --- University of Johannesburg, South Africa Jody M Barends --- University of Johannesburg, South Africa Eli Greenbaum --- University of Texas at El Paso, USA Werner Conradie --- Port Elizabeth Museum (Bayworld), South AfricaAfrican night adders (Causus) are an enigmatic group of viperid snakes in the subfamily Viperinae. These snakes have a suite of unusual characters atypical of other species of vipers (e.g., oviparous reproduction, round pupils) but are firmly placed within the...
