Ontogenetic dietary shift and morphological correlates for Diplodus capensis (Teleostei: Sparidae) in southern Angola
Item type: Journal Article • Journal: African Zoology • Authors: Timothy J. Richardson --- Department of Ichthyology and Fisheries Science, South Africa Warren M. Potts --- Department of Ichthyology and Fisheries Science, South Africa Carmen V. Santos --- Faculdade Ciências da Universidade Agostinho Neto (FCUAN), Angola Warwick H.H. Sauer --- Department of Ichthyology and Fisheries Science, South AfricaAllometric growth patterns of functional morphological variables that reflect resource use in fish were correlated with the diet of Diplodus capensis in southern Angola. A total of 114 individuals (76–336 mm FL) were collected for stomach content analysis and a... -
Summarising biometrics from the SAFRING database for southern African birds
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Sanjo Rose --- , South Africa Robert L Thomson --- , South Africa Hans-Dieter Oschadleus --- , South Africa Alan TK Lee --- , South AfricaBiometrics form a key characteristic of a species. Here, we provide a summary of biometrics held by the South African Bird Ringing Scheme (SAFRING), which was initiated in 1948, including measures of mass and lengths of the tarsus, head, culmen,... -
Convergence and vicariance: speciation of chameleons in the Cape Fold Mountains, South Africa, and the description of three new species of Bradypodion Fitzinger, 1843
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Krystal A Tolley --- South African National Biodiversity Institute, South Africa Colin R Tilbury --- University of Stellenbosch, South Africa Marius Burger --- North-West University, South AfricaThe mechanisms that underpin ecological speciation, morphological convergence and the evolution of ecological morphotypes (ecomorphs) in squamates have allowed for a better appreciation of the speciation process in chameleons. In particular, attention has been drawn to several populations of chameleons... -
Is it like night and day? Nocturnal versus diurnal perch use by dwarf chameleons (Bradypodion pumilum)
Item type: Journal Article • Journal: Treading a Delicate Tightrope: A principal balancing between education and political change during turbulent times • Authors: Krystal A Tolley --- , South AfricaArboreal chameleons must navigate a complex, three-dimensional landscape consisting of trees, bushes and/or grasses of various sizes. This complexity equates to the microhabitat of chameleons, that is, the branches upon which they perch and through which they move. Therefore, chameleons...
