Towards a standardized and optimized protocol for rapid biodiversity assessments: spider species richness and assemblage composition in two savanna vegetation types
(South African Journals, 2010-10)
A semi-quantitative inventory of spider diversity was done in the Blouberg Nature Reserve (BNR) and Western Soutpansberg Conservancy (WSC) situated in the Savanna Biome of the Limpopo Province, South Africa. Two hundred ...
South African National Survey of Arachnida (SANSA): review of current knowledge, constraints and future needs for documenting spider diversity (Arachnida: Araneae)
(Taylor & Francis, 2015-10-07)
Biodiversity is one of the most important concepts in contemporary biology, with a broad range of applications. In November 1995, South Africa ratified the Convention on Biological Diversity (CBD). Signatories are obligated ...
The effect of elevation and time on mountain spider diversity: a view of two aspects in the Cederberg mountains of South Africa
(John Wiley & Sons Ltd, 2016)
Aim Our aim is to test if long-term patterns in α alpha and ß beta diversity along an elevational transect on two aspects of a mountain are consistent through time using spiders as model organisms, quantify the role of ...
A new species of Hersilia Audouin, 1826 (Araneae: Hersiliidae) from India, with notes on its natural history
(Magnolia Press, 2010-09-15)
A new species of Hersilia Audouin, H. orvakalensis sp. nov., is described from Andhra Pradesh, India. The taxonomic affinities of the species are discussed and a brief note on its natural history is provided.
South African National Survey of Arachnida: A checklist of the spiders(Arachnida, Araneae) of the Lekgalameetse Nature Reserve, Limpopo province, South Africa
The aim of the South African National Survey of Arachnida (SANSA) is to document the Arachnida fauna of South Africa. One of the focus areas of SANSA is to survey protected areas to obtain species-specific information, ...
Redescriptions of poorly known species of jumping spiders (Araneae: Salticidae) from South Africa and Namibia
(Magnolia Press, 2013-07-11)
The following seven species of southern African Salticidae, known only from type specimens or one sex, and last described in the early 20th century, are redescribed: Baryphas ahenus Simon, 1902, Brancus muticus Simon, ...
The faunistic diversity of spiders (Arachnida: Araneae) of the Savannah Biome of South Africa
(Taylor & Francis, 2011)
Invertebrates include more than 80% of all animals, yet they are severely under-represented in studies of southern African diversity. Site biodiversity estimates that ignore invertebrates, not only omit the greatest part ...
Microclimates mitigate against hot temperatures in dryland ecosystems: termite mounds as an example
(Ecological Society of America, 2016)
Termite mounds have recently been shown to protect against drought by providing refuges for plants and foci for revegetation, but whether mounds modulate temperature remains untested. Organisms tend to experience climate ...
Ant assemblages have darker and larger members in cold environments
(John Wiley & Sons Ltd, 2016)
Aim In ectotherms, the colour of an individual’s cuticle may have important thermoregulatory and protective consequences. In cool environments, ectotherms should be darker, to maximize heat gain, and larger, to minimize ...
Long term response of benthic aquatic macroinvertebrates and adult Odonata to alien invasive clearing
Report on the long-term effects of invasive alien plant clearing on macroinvertebrate and adult odonata assemblages
