Helminths from three species of African chameleons
Item type: Journal Article • Journal: African Zoology • Authors: Stephen R. Goldberg --- Department of Biology, U.S.A. Charles R. Bursey --- Department of Biology, U.S.A.Three species of African chameleons (Chamaeleo gracilis, C. jacksoni and C. johnstoni) were examined for helminths. Two species of Cestoda (Oochoristica truncata and tetrathyridia of Mesocestoides sp.) and four species of Nematoda (Oswaldocruzia chamaeleonis, Parapharyngodon kenyaensis,Raillietnema chamaeleo, and Strongyluris elegans)... -
Chameleons on the move: survival and movement of the Cape dwarf chameleon, Bradypodion pumilum, within a fragmented urban habitat
Item type: Journal Article • Journal: African Zoology • Authors: Krystal A. Tolley --- Applied Biodiversity Research Division, South African National Biodiversity Institute, South Africa Robert N.V. Raw --- Applied Biodiversity Research Division, South African National Biodiversity Institute, South Africa Res Altwegg --- Applied Biodiversity Research Division, South African National Biodiversity Institute, South Africa John G. Measey --- Applied Biodiversity Research Division, South African National Biodiversity Institute, South AfricaReptiles have an amazing diversity of life-history attributes ranging from the shortest- to longest-lived of vertebrate species. Estimating survival in wild populations is of key importance when understanding population dynamics and life-history evolution. However, data are lacking for a large... -
Out on a limb: female chameleons (Bradypodion pumilum) position themselves to minimise detection, whereas males maximise mating opportunity
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Alexander D Rebelo --- South African National Biodiversity Institute, Kirstenbosch Research Centre, Claremont, South Africa Res Altwegg --- University of Cape Town, South Africa Eric M Katz --- South African National Biodiversity Institute, Kirstenbosch Research Centre, Claremont, South Africa Krystal A Tolley --- South African National Biodiversity Institute, Kirstenbosch Research Centre, Claremont, South AfricaAlthough reproductive strategies are poorly documented in chameleons, sperm storage has been confirmed among some species for which male reproductive success may be maximised by increasing the number of females inseminated and/or preventing subsequent female copulation with rival males. Behaviour,... -
A new Dwarf Chameleon (Sauria: Bradypodion Fitzinger, 1843) from the Cape Fold Mountains, South Africa
Item type: Journal Article • Journal: The Journal of the Herpetological Association of Africa • Authors: WilliamR. Branch --- Bayworld (Port Elizabeth Museum), South Africa KrystalA. Tolley --- South African National Biodiversity Institute, South Africa ColinR. Tilbury --- University of Stellenbosch, South AfricaA new dwarf chameleon, Bradypodion atromontanum Branch, Tolley & Tilbury sp. nov., is described from mountain fynbos habitat in the Great Swartberg Mountains, Western Cape Province, South Africa. It is closest geographically to Bradypodion gutturale but distinguished by its smaller... -
Chameleons and vineyards in the Western Cape of South Africa: Is automated grape harvesting a threat to the Cape Dwarf Chameleon (Bradypodion pumilum)?
Item type: Journal Article • Journal: The Journal of the Herpetological Association of Africa • Authors: KrystalA. Tolley --- South African National Biodiversity Institute, South Africa G. John Measey --- University of the Western Cape, South AfricaThe use of automated grape harvesters in the Cape Wine Growing region has resulted in controversy regarding their effect on the chameleon Bradypodion pumilum. We investigated densities of B. pumilum during harvesting at a vineyard near Stellenbosch, South Africa. During... -
A new species of chameleon (Sanria: Chamaeleonidae: Kinyongia) from the Magombera forest and the Udzungwa Mountains National Park, Tanzania
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Michele Menegon --- Museo Tridentino di Scienze Naturali, Italy KrystalA. Tolley --- South African National Biodiversity Institute, Kirstenbosch Research Centre, South Africa Trevor Jones --- c/o Udzungwa Mountains National Park, Tanzania Francesco Rovero --- Museo Tridentino di Scienze Naturali, Italy AndrewR. Marshall --- University of York, UK ColinR. Tilbury --- University of Stellenbosch, South AfricaA new species of chameleon Kinyongia magomberae sp. nov. (the Magombera chameleon), is described from Magombera forest and the Vdzungwa Mountains National Park, south-central Tanzania. The species status is supported by phylogenetic analyses using mitochondrial and nuclear markers. The new... -
Predation on chameleons in Madagascar: a review
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Richard K. B. Jenkins --- School of Biological Sciences, University of Aberdeen, UK Jeanneney Rabearivony --- The Peregrine Fund, Madagascar Hajanirina Rakotomanana --- University of Antananarivo, MadagascarWe reviewed the diet of nocturnal and diurnal chameleon predators on Madagascar from the available literature and identified 28 species. Diurnal raptors were the main predators of chameleons, although the literature was biased towards birds and probably underestimated predation by... -
A new species of chameleon (Sauria: Chamaeleonidae: Nadzikambia) from Mount Mabu, central Mozambique
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: WilliamR. Branch --- Port Elizabeth Museum, South Africa KrystalA. Tolley --- South African National Biodiversity Institute, South AfricaNadzikambia is a monotypic genus described to accommodate the Mulanje chameleon, N. mlanjensis. During herpetological surveys of isolated mountains in Mozambique a population of chameleons was discovered on Mount Mabu. It is referable to the genus Nadzikambia, but features of... -
Calumma vohibola, a new chameleon species (Squamata: Chamaeleonidae) from the littoral forests of eastern Madagascar
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Philip-Sebastian Gehring --- Technical University of Braunschweig, Germany FanomezanaM. Ratsoavina --- Technical University of Braunschweig, Germany Miguel Vences --- Technical University of Braunschweig, Germany Frank Glaw --- Zoologische Staatssammlung München, GermanyWe describe Calumma vohibola sp. nov., a morphologically distinct chameleon species of the Calumma nasutum species group from littoral forest fragments of the north-central east coast of Madagascar. Males and females of this species differ from all other species of... -
Temporal changes in allelic variation among Cape Dwarf Chameleons, Bradypodion pumilum, inhabiting a transformed, semi-urban wetland
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Eric M. Katz --- , , South Africa Krystal A. Tolley --- , , South Africa Jacqueline M. Bishop --- , , South AfricaThe Cape Dwarf Chameleon, Bradypodion pumilum, is threatened by extensive habitat loss and transformation in the Western Cape Province of South Africa. As a result, the species exists as a collection of populations inhabiting an increasingly fragmented landscape within a... -
Multiple paternity and sperm storage in the Cape Dwarf Chameleon (Bradypodion pumilum)
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Krystal A. Tolley --- , , South Africa Lucas F. Chauke --- , , South Africa Jennifer C. Jackson --- , , South Africa Kevin A. Feldheim --- , , USAAlthough multiple paternity and sperm storage are common in squamates, neither has been conclusively demonstrated in the chameleons (Chamaeleonidae). To examine whether these traits are present in chameleons, the Cape Dwarf Chameleon (Bradypodion pumilum) was investigated. This viviparous species inhabits...
