Oribatid mites of the genus Allonothrus (Acari: Oribatida: Crotonioidea) of the Ethiopian region with the description of a new subspecies
Item type: Journal Article • Journal: African Zoology • Authors: Ziemowit Olszanowski --- Department of Animal Taxonomy and Ecology, Adam Mickiewicz University, Poland Natalia Bochniak --- Department of Animal Taxonomy and Ecology, Adam Mickiewicz University, PolandSummary data on oribatid mites of the genus Allonothrus (Trhypochthoniidae) of the Ethiopian region are presented. A new subspecies, Allonothrus schuilingi seychelli nov. subsp., is described from Seychelles. It is distinguished on the basis of the shape and length of... -
Reproductive seasonality of southern African inshore and estuarine invertebrates – a biogeographic review
Item type: Journal Article • Journal: African Zoology • Authors: Alan N. Hodgson --- Department of Zoology and Entomology, South AfricaA literature review reveals that reproductive seasonality of less than 1% of South Africa’s inshore marine invertebrates has been studied. Approximately 95% of studies have been on large, long-lived, gonochoristic, iteroparous species, and nearly 50% on molluscs. There is only... -
The phylogenetic affinities of Trachylepis sulcata nigra and the intraspecific evolution of coastal melanism in the western rock skink
Item type: Journal Article • Journal: African Zoology • Authors: Daniel M. Portik --- Department of Biology, U.S.A. Aaron M. Bauer --- Department of Biology, U.S.A. Todd R. Jackman --- Department of Biology, U.S.A.The phylogenetic affinities of the melanistic subspecies Trachylepis sulcata nigra have never been investigated, and it was unclear if this subspecies represented a locally adapted population or a distinct species. Sequences from the nuclear marker RAG-1 (1149 bp), two novel... -
Phylogeography of the pelagic fish Seriola lalandi at different scales: confirmation of inter-ocean population structure and evaluation of southern African genetic diversity
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: BL Swart --- Molecular Breeding and Biodiversity Group, Department of Genetics, South Africa AE Bester-van der Merwe --- Molecular Breeding and Biodiversity Group, Department of Genetics, South Africa SE Kerwath --- Department of Agriculture, South Africa R Roodt-Wilding --- Molecular Breeding and Biodiversity Group, Department of Genetics, South AfricaThe study investigated the global and regional phylogeography of the yellowtail kingfish Seriola lalandi by examining genetic diversity and population genetic structure of this species at inter-and intra-ocean level and on a regional scale. DNA fragments of two mitochondrial genes,... -
Morphological variation in the Sabota Lark Calendulauda sabota in southern Africa
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Sean M Marr --- Department of Biodiversity, South Africa Mmatjie L Mashao --- Department of Biodiversity, South Africa G Derek Engelbrecht --- Department of Biodiversity, South AfricaSeparation of the eight southern African subspecies of Sabota Lark Calendulauda sabota into thick-billed and slender-billed groups has been proposed. This study used biometric data obtained from museum skins in South Africa to evaluate morphological variation in the subspecies as... -
Large Pleistocene avian tracks on the Cape south coast of South Africa
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Charles W Helm --- , South Africa Martin G Lockley --- , United States Hayley C Cawthra --- , South Africa Jan C De Vynck --- , South Africa Carina JZ Helm --- , South Africa Guy HH Thesen --- , South AfricaPrior to the inception of the Cape south-coast ichnology project, only one avian tracksite had been reported from South Africa. An additonal twenty-nine sites have now been identified. Although there are limitations and challenges inherent in the study of fossil... -
Genetic and morphological variation of Woodland Kingfisher Halcyon senegalensis reveals cryptic mitochondrial lineages and patterns of mitochondrial–nuclear discordance
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Monica Mwale --- South African National Biodiversity Institute (SANBI), South Africa Desiré L Dalton --- South African National Biodiversity Institute (SANBI), South Africa Anna S Kropff --- South African National Biodiversity Institute (SANBI), South Africa Kim Labuschagne --- South African National Biodiversity Institute (SANBI), South Africa Isa-Rita Russo --- Cardiff University, United Kingdom Samuel T Osinubi --- University of Cape Town, South AfricaThe Woodland Kingfisher Halcyon senegalensis is widely distributed throughout sub-Saharan Africa and occupies a wide variety of woodland and savannah habitat. Thus far, three subspecies have been described based on morphological variation. In the present study, using western, eastern and... -
Pleistocene Hamerkop Scopus umbretta (Scopidae) tracks and other new avian ichnosites on South Africa’s Cape south coast
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Charles W Helm --- Nelson Mandela University, South Africa Given Banda --- Nelson Mandela University, South Africa Andrew S Carr --- University of Leicester, United Kingdom Hayley C Cawthra --- Nelson Mandela University, South Africa Jan C de Vynck --- Nelson Mandela University, South Africa Mark G Dixon --- Nelson Mandela University, South Africa Alex van den Heever --- Magazine Hill, South AfricaEight Pleistocene avian ichnosites have been identified in aeolianites on South Africa’s Cape south coast, adding to the 41 sites previously identified. All the newly identified sites are thought to fall within the age range of marine isotope stages (MIS)...
