Chemical signalling in lizards: an interspecific comparison of femoral pore numbers in Lacertidae
Animals communicate via a variety of sensory channels and signals. Studies on acoustic and visual communication systems suggest that differences in the physical environment contribute to the varietyExpand

Convergent Evolution Associated with Habitat Decouples Phenotype from Phylogeny in a Clade of Lizards
Convergent evolution can explain similarity in morphology between species, due to selection on a fitness-enhancing phenotype in response to local environmental conditions. As selective pressures onExpand

Is dietary niche breadth linked to morphology and performance in Sandveld lizards Nucras (Sauria: Lacertidae)?
The functional characteristics of prey items (such as hardness and evasiveness) have been linked with cranial morphology and performance in vertebrates. In lizards particularly, species with moreExpand

Habitat characteristics influence the breeding of Rose’s dwarf mountain toadlet Capensibufo rosei (Anura: Bufonidae).
Direct anthropogenic factors (e.g., habitat loss, fragmentation, and degradation) threaten many amphibian populations, however some declines have occurred in supposedly pristine environments with noExpand

Two new species of Acontias (Acontinae, Scincidae) from the Mpumalanga Highveld escarpment of South Africa.
The African genus of fossorial legless lizards (Acontias Cuvier) currently comprises 26 species and subspecies. In a recent study on the two disjunct populations of Acontias breviceps Essex, theExpand

Analysis of genetic diversity in Rose’s mountain toadlet (Capensibufo rosei) using novel microsatellite markers
Abstract On the Cape Peninsula, Capensibufo rosei is known from only two isolated breeding populations within Table Mountain National Park. Because of its declining state, there is an urgent need toExpand
