Herpetofaunal Survey of the Ongeluksnek (Malekgalonyane) Nature Reserve in the Foothills of the Drakensberg, Eastern Cape Province, South Africa
Herpetology Notes, volume 13: 717-730 (2020) (published online on 25 August 2020) Herpetofaunal survey of the Ongeluksnek (Malekgalonyane) Nature Reserve in the foothills of the Drakensberg, Eastern Cape Province, South Africa Werner Conradie1,2,* Brian Reeves3, Sandile Mdoko3, Lwandiso Pamla3, and Oyama Gxabhu3 Abstract. The results of a herpetofaunal survey of Ongeluksnek Nature Reserve, Eastern Cape Province, South Africa are presented here. Combination of visual encounter survey methods and standard Y-shape trap arrays were used to conduct the survey. A total of 26 species (eight amphibians and 18 reptiles) were recorded, representing 29 quarter-degree grid cell records, of which 62% represented the first records for these units. Furthermore, we document the presence of three species of snakes (Crotaphopeltis hotamboeia, Hemachatus haemachatus and Homoroselaps lacteus) for the first time for the whole degree square of 3028 (approx. 100 km2). This study highlights the need to survey poorly known regions to enable us to understand and document the full distributional extent of species. We also discuss the impact of uncontrolled fires on the absence of grassland specialised species during our survey. Keywords.

The present geological period has more species than any other, yet the current rate of extinction of species is greater now than at any time in the past. Ecosystems and communities are being degraded and destroyed, and species are being driven to extinction. The species that persist are losing genetic variation as the number of individuals in populations shrinks, unique populations and subspecies are destroyed, and remaining populations become increasingly isolated from one another. The cause of this loss of biological diversity at all levels is the range of human activity that alters and destroys natural habitats to suit human needs.” (Primack, 2002). CapeNature launched its State of Biodiversity Programme (SoBP) to assess and monitor the state of biodiversity in the Western Cape in 1999. This programme delivered its first report in 2002 and these reports are updated every five years. The current report (2007) reports on the changes to the state of vertebrate biodiversity and land under conservation usage. -

In lizards particularly, species with more robust crania generally feed on harder prey items and possess a greater bite force, whereas those that prey on evasive prey typically have longer snouts. However, the link between dietary niche breadth, morphology, and performance has not been explicitly investigated in lizards. The southern African genus Nucras was used to investigate this link because the species exhibit differing niche breadth values and dietary compositions. A phylogeny for the genus was established using mitochondrial and nuclear markers, and morphological clusters were identified. Dietary data of five Nucras species, as reported previously, were used in correlation analyses between cranial shape (quantified using geometric morphometrics) and dietary niche breadth, and the proportion of hard prey taken and bite force capacity. -

E-mail: [email protected] Abstract A striking new sandveld lizard of the Nucras tessellata group is described from the Lambert’s Bay Strandveld of the West- ern Cape Province, South Africa. It is sister to the clade N. livida + N. tessellata, and is phenetically most similar to N. tessellata, from which it differs in its more elongate body and possibly increased number of presacral vertebrae and pat- ternless orange dorsal coloration. The form elegans, described as a species by Andrew Smith (1838), but treated as an infrasubspecific variant by Broadley (1972), also exhibits weak patterning, but is likely a regional color variant. Nucras aurantiaca sp. nov. is the ninth member of the genus found in southern Africa. -

Instead, we examine the rate of production (productivity of Biological Sciences, University of Reading, hereafter) calculated as the total mass of offspring produced in a year. We test ReadingRG6 6AS, UK whether productivity is influenced by proxies of adult mortality rates such as insularity and fossorial habits, by measures of temperature such as environmental and body temperatures, mode of reproduction and activity times, and by environ- mental productivity and diet. We further examine whether low productivity is linked to high extinction risk. Location World-wide. Methods We assembled a database containing 551 lizard species, their phyloge- netic relationships and multiple life history and ecological variables from the lit- erature. We use phylogenetically informed statistical models to estimate the factors related to lizard productivity. Results Some, but not all, predictions of metabolic and life-history theories are supported. When analysed separately, clutch size, relative clutch mass and brood frequency are poorly correlated with body mass, but their product – productivity – is well correlated with mass. The allometry of productivity scales similarly to metabolic rate, suggesting that a constant fraction of assimilated energy is allocated to production irrespective of body size. -

The Biodiversity Foundation for Africa is responsible for acquiring technical information on the biodiversity of the project area. The Zambezi Society will be interpreting this information into user-friendly formats for stakeholders in the Four Corners area, and then disseminating it to these stakeholders. THE BIODIVERSITY FOUNDATION FOR AFRICA (BFA is a non-profit making Trust, formed in Bulawayo in 1992 by a group of concerned scientists and environmentalists. Individual BFA members have expertise in biological groups including plants, vegetation, mammals, birds, reptiles, fish, insects, aquatic invertebrates and ecosystems. The major objective of the BFA is to undertake biological research into the biodiversity of sub-Saharan Africa, and to make the resulting information more accessible. Towards this end it provides technical, ecological and biosystematic expertise. THE ZAMBEZI SOCIETY was established in 1982. Its goals include the conservation of biological diversity and wilderness in the Zambezi Basin through the application of sustainable, scientifically sound natural resource management strategies. -
