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 ...
Accommodating scenarios of climate change and management in modelling the distribution of the invasive tree Schinus molle in South Africa
Determining the potential range of invasive alien species under current conditions is important. However, we also need to consider future distributions under scenarios of climate change and different management interventions ...
Bioregion heterogeneity correlates with extensive mitochondrial DNA diversity in the Namaqua rock mouse, Micaelamys namaquensis (Rodentia: Muridae) from southern Africa - evidence for a species complex
(BioMed Central Ltd., 2010)
Background: Intraspecific variation within the diverse southern African murine rodents has not been extensively investigated, yet cryptic diversity is evident in several taxa studied to date. The Namaqua rock mouse, ...
Disentangling the dynamics of invasive fireweed (Senecio madagascariensis Poir. species complex) in the Hawaiian Islands
(Springer Science+Business Media B.V., 2010)
Studies investigating the genetic variation of invasive species render opportunities to better understand the dynamics of biological invasions from an ecological and evolutionary perspective. In this study, we investigate ...
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.
Ontogenetic variation and craniometric sexual dimorphism in the social giant mole-rat, Fukomys mechowii (Rodentia: Bathyergidae), from Zambia
The degree of maxillary molar tooth-row eruption and wear were used to assign samples of the social giant mole-rat, Fukomys mechowii, from Zambia, into nine relative age classes in order to assess ontogenetic (age) variation ...
Effect of wave action on the rehabilitation success of the brown mussel Perna perna in Coffee Bay
The study looked at the effect of wave action on the rehabilitation success of the brown mussels Perna perna in Coffee Bay. There is a Mussel Rehabilitation Project which attaches mussels onto the rocks and rehabilitation ...
Sutherland climate data 2008
The Sutherland Long-term Site investigates invertebrate physiology and the climate the invertebrates experience at two sites on a farm 20km from Sutherland in the Northern Cape, South Africa. It is a long term project, ...
Current and future vulnerability of South African ecosystems to perennial grass invasion under global change scenarios
Invasive alien grasses are a group of increasing importance which respond to global changes and alter native plant community structure and ecosystem processes. To date there have been few studies that assess the ecological ...
The BIOTA Observatories
(Klaus Hess Publishers, 2010)
The BIOTA Southern Africa transects (Fig. 1, on left side) have been designed to describe biodiversity changes in space and time along two major climatic gradients in the western part of southern Africa (see also ...
