Sexual size dimorphism in the lizard Oplurus cuvieri cuvieri (Squamata, Opluridae) from Madagascar
Item type: Journal Article • Journal: African Zoology • Authors: Herilala J.A.R Randriamahazo --- Department of Zoology, JapanSexual size dimorphism in the medium-sized lizard Oplurus cuvieri cuvieri, which is endemic to the dry deciduous forest of Madagascar, is presented. Adults are sexually dimorphic in body size, head size, and tail length. Males have a greater snout–vent length... -
Sexual dimorphism in morphological traits and scaling relationships in two populations of Gallotia stehlini (Fam. Lacertidae: Squamata) from Gran Canaria
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Cristina Rivero Suárez --- , , Spain Miguel Angel Rodríguez-Domínguez --- , Miguel Molina-Borja --- , , SpainLizards of the genus Gallotia, endemic to the Canary Islands, show morphological and colouration varieties that are related to within island variation in orographic and climatic characteristics. This study examines sexual size dimorphism (SSD) within and between population variation in... -
New distributional data and genetic variation of Panaspis breviceps (Squamata: Scincidae) indicate a biogeographic connection across the Congo Basin
Item type: Journal Article • Journal: African Zoology • Authors: Albert L Lokasola --- , Democratic Republic of the Congo Cédric Botshuna Lotana --- , Democratic Republic of the Congo Guy-Crispin Gembu Tungaluna --- , Democratic Republic of the Congo Benjamin Dudu Akaibe --- , Democratic Republic of the Congo Miloslav Jirků --- , Czech Republic Václav Gvoždík --- , Czech RepublicIn the central Congolian lowland forests we discovered for the first time Panaspis breviceps, a rarely found scincid lizard from the Central African riparian forests. Given that the Central African forests exhibit heterogeneity in the distribution of environmental characteristics and... -
Interspecific aggression in flat lizards suggests poor species recognition
Item type: Journal Article • Journal: The Journal of the Herpetological Association of Africa • Authors: Pius Korner --- ETH‐Zentrum NW, Switzerland MartinJ. Whiting --- University of the Witwatersrand, South Africa J. Willem --- University of Pretoria, South Africa H. Ferguson --- University of Pretoria, South AfricaMistaken identity and competitive exclusion are two alternative hypotheses proposed to explain interspecific aggression between males. We examined agonistic behaviour in males of two lizard species: Platysaurus minor and P. monotropis. In each of nine outdoor field enclosures, we maintained... -
The comparative diet of three Saharan sand dune skinks
Item type: Journal Article • Journal: The Journal of the Herpetological Association of Africa • Authors: Omar Attum --- University of Louisville, Charles Covell --- University of Louisville, Perri Eason --- University of Louisville,We compared the diets of the only three sand dune skinks of North Sinai, Chalcides ocellatus, Scincus scincus, and Sphenops sepsoides. Despite our small sample size, we found several interesting trends. Coleoptera was the most common prey order eaten by... -
A molecular phylogeny for sub-Saharan amphisbaenians
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: G. John Measey --- , , South Africa Krystal A. Tolley --- , , South AfricaAmphisbaenians are enigmatic members of the subterranean herpetofauna with the majority of their diversity concentrated in South America and Africa. The largest family, Amphisbaenidae, occurs in South America and Africa, but the phylogenetic relationships among the genera are not clearly... -
Multiple paternity and sperm storage in the Cape Dwarf Chameleon (Bradypodion pumilum)
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Krystal A. Tolley --- , , South Africa Lucas F. Chauke --- , , South Africa Jennifer C. Jackson --- , , South Africa Kevin A. Feldheim --- , , USAAlthough multiple paternity and sperm storage are common in squamates, neither has been conclusively demonstrated in the chameleons (Chamaeleonidae). To examine whether these traits are present in chameleons, the Cape Dwarf Chameleon (Bradypodion pumilum) was investigated. This viviparous species inhabits... -
Two new species of Hemidactylus Goldfuss, 1820 (Squamata: Gekkonidae) from the coastal areas of northern Somaliland
Item type: Journal Article • Journal: African Zoology • Authors: Tomáš Mazuch --- Mendel University, Czech Republic Vojtěch Janák --- Charles University, Czech Republic Doubravka Velenská --- Charles University, Czech Republic Annamaria Nistri --- Museo di Storia Naturale dell’Univesità degli Studi di Firenze, Italy Hassan Sh Abdirahman Elmi --- Charles University, Czech Republic Jiří Šmíd --- Charles University, Czech RepublicThe taxonomy of many Hemidactylus geckos from the Horn of Africa has recently been evaluated. However, the lack of fresh material for some species and also regions has led to the misidentification of some taxa and an underestimation of the...
