Reproductive cycle of the Namaqua sand lizard, Pedioplanis namaquensis (Squamata: Lacertidae), from southern Africa
Item type: Journal Article • Journal: African Zoology • Authors: Stephen R. Goldberg --- Department of Biology, U.S.A.The reproductive cycle of the Namaqua sand lizard, Pedioplanis namaquensis, from southern Africa is described from histological examination of gonadal material from museum specimens. Males followed a seasonal testicular cycle in which sperm was produced in January–March and September–December. Testes... -
Helminths of seven species of lacertid lizards from southern Africa
Item type: Journal Article • Journal: African Zoology • Authors: Stephen R. Goldberg --- Department of Biology, Whittier College, U.S.A Charles R. Bursey --- Department of Biology, Pennsylvania State University, U.S.ATwo hundred and forty five lacertid lizards representing seven species (Heliobolus lugubris, Ichnotropis squamulosa, Meroles anchietae, M. cuneirostris, M. suborbitalis, Pedioplanis lineoocellata, P. namaquensis) from southern Africa were examined for helminths. Adults of one species of cestode, Oochoristica ubelakeri, and... -
Characterisation of microsatellite markers in the Spotted Sand Lizard (Pedioplanis lineoocellata) shows low levels of inbreeding and moderate genetic diversity on a small spatial scale
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Krystal A. Tolley --- , , South Africa Ryan J. Daniels --- , , South Africa Kevin A. Feldheim --- , , USAPopulation genetic methods can be useful for understanding spatial genetic patterns, gene flow and diversity. While genetic markers such as gene sequences are useful for understanding broad scale phylogeographic patterns, microsatellite markers allow for inferences within species and on smaller... -
Cryptic variation in the Moroccan high altitude lizard Atlantolacerta andreanskyi (Squamata: Lacertidae)
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Mafalda Barata --- , , Portugal Ana Perera --- , , Portugal D. James Harris --- , , PortugalAtlantolacerta andreanskyi is a mountain specialist lacertid lizard, restricted to areas above 2400 m of the High Atlas Mountains of Morocco, with apparently no geographic connection between different populations. In a recent molecular study, populations from A. andreanskyi collected across... -
Intraspecific behavioural variation in the lacertid lizard Meroles cuneirostris (Strauch, 1867) (Sauria:Lacertidae)
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Jackie L. Childers --- , , USA Douglas A. Eifler --- , USAWe characterised behavioural variation between adult male, adult female and juvenile Meroles cuneirostris, a diurnal lacertid lizard endemic to the Namib Desert. Variation in microhabitat preference was significant between age classes, as adults spent more time underneath vegetative cover than... -
Sexual size dimorphism in a Tunisian population of Bosk's fringe-toed lizards Acanthodactylus boskianus asper
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Intissar Nasri --- , , Tunisia Abdessalem Hammouda --- , , Tunisia Foued Hamza --- , , Tunisia Slaheddine Selmi --- , , TunisiaInvestigating how patterns of sexual size dimorphism vary among local populations may be useful for understanding size evolution in lizards. We investigated patterns of sexual size dimorphism in a Tunisian population of Bosk's fringe-toed lizards Acanthodactylus boskianus asper, in relation... -
Phylogenetic position of the southern rock lizard Australolacerta australis within the Lacertidae radiation
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Daniele Salvi --- CIBIO, Centro de Investigação em Biodiversidade e Recursos Genéticos, Portugal Pierluigi Bombi --- SPACEnvironment, Italy Leonardo Vignoli --- Roma Tre University, ItalyThe southern rock lizard Australolacerta australis is a rock-dwelling lizard endemic to South Africa. The phylogenetic relationships of this species with other lacertid lizards are still not clear and have never been assessed in any phylogeny of Lacertidae using DNA... -
Revised phylogeny of African sand lizards (Pedioplanis), with the description of two new species from south-western Angola
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Werner Conradie --- , South Africa G. John Measey --- South African National Biodiversity Institute, South Africa WilliamR. Branch --- , South Africa KrystalA. Tolley --- South African National Biodiversity Institute, South AfricaAlthough reptile diversity in Africa is high, it is poorly represented in Angola, with just 257 species known. Despite its greater surface area and habitat diversity Angola has significantly lower lacertid lizard diversity than adjacent Namibia. This is particularly notable... -
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...
