Exploring the diversity and molecular evolution of shrews (family Soricidae) using mtDNA cytochrome b data
Item type: Journal Article • Journal: African Zoology • Authors: Sandi Willows-Munro --- Evolutionary Genomics Group, Department of Botany and Zoology, South Africa Conrad A. Matthee --- Evolutionary Genomics Group, Department of Botany and Zoology, South AfricaThe taxonomy of the shrews (family Soricidae) is primarily underpinned by the analysis of morphology characters. These morphological characters are, however, often plesiomorphic and difficult to interpret in an evolutionarily meaningful way. Recent molecular studies have provided some clarity at... -

Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Luke Verburgt --- , , South Africa Ursula K. Verburgt --- , , South Africa William R. Branch --- , South AfricaSeven specimens of Scolecoseps Loveridge, 1920 from the vicinity of Palma on the north coast of Mozambique are compared morphologically with other known material of this genus. The new material can be distinguished morphologically from all other Scolecoseps by the... -

Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Romy Rice --- Department of Evolutionary Zoology and Human Biology, Hungary José O Valdebenito --- Milner Centre for Evolution, United Kingdom Meinolf Ottensmann --- Department of Animal Behaviour, Germany Noémie Engel --- Department of Evolutionary Zoology and Human Biology, Hungary Andreia Adrião --- Maio Biodiversity Foundation, Republic of Cape Verde Tamás Székely --- Department of Evolutionary Zoology and Human Biology, HungaryThe Cream-coloured Courser Cursorius cursor exsul is a data-deficient shorebird distributed across Eurasia and Africa. The subspecies exsul is endemic to the Cape Verde archipelago. In contrast with their mainland breeding sites, where coursers appear to be nomadic and rare... -
Digging adaptations evolved independently in two lineages of Psammophiid snake: evidence from cranial morphology
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Nick Sekits --- Whitman College, United States Walter Tunnell-Wilson --- Whitman College, United States Kate Jackson --- Whitman College, United StatesThe Beaked Snakes (Rhamphiophis) are semi-fossorial snakes with reinforced snouts adapted for digging. The Skaapstekers (Psammophylax) are generalist terrestrial snakes. Both belong to the family, Psammophiidae. The Striped Beaked Snake (Kladirostratus acutus) was originally assigned to the genus Rhamphiophis, because... -
