South African National Survey of Arachnida (SANSA) : review of current knowledge, constraints and future needs for documenting spider diversity (Arachnida: Araneae)

TLDR
The South African National Survey of Arachnida (SANSA) was initiated in 1997 as discussed by the authors to document and describe the arachnid fauna of South Africa, to consolidate all the available data on South African arachns into one relational database and to make this biodiversity information available to science; and to address issues concerning their conservation and sustainable use.
Abstract
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 to develop a strategic plan for the conservation and sustainable use of biodiversity. To meet the requirements of the CBD, the South African National Survey of Arachnida (SANSA) was initiated in 1997. This national project has several aims: to document and describe the arachnid fauna of South Africa; to consolidate all the available data on South African arachnids into one relational database and to make this biodiversity information available to science; and to address issues concerning their conservation and sustainable use. Extensive sampling took place and the SANSA database contains a wealth of biodiversity data that are used to provide answers to ecological questions. Presently 71 spider families, 471 genera and 2170 species are known from South Africa, representing approximately...

Biodiversity hotspots for conservation priorities

TL;DR: A ‘silver bullet’ strategy on the part of conservation planners, focusing on ‘biodiversity hotspots’ where exceptional concentrations of endemic species are undergoing exceptional loss of habitat, is proposed.

Biological identifications through DNA barcodes

TL;DR: It is established that the mitochondrial gene cytochrome c oxidase I (COI) can serve as the core of a global bioidentification system for animals and will provide a reliable, cost–effective and accessible solution to the current problem of species identification.

TL;DR: Most indicators of the state of biodiversity showed declines, with no significant recent reductions in rate, whereas indicators of pressures on biodiversity showed increases, indicating that the Convention on Biological Diversity’s 2010 targets have not been met.

TL;DR: A review by Czech and colleagues (2000) finds that urbanization endangers more species and is more geographically ubiquitous in the mainland United States than any other human activity, emphasizing the uniquely far-reaching transformations that accompany urban sprawl as discussed by the authors.

Biological Identifications Through DNA Barcodes

TL;DR: It was established previously that the mitochondrial gene cytochrome c oxidase I can serve as the core of a global bioidentification system for animals and a new tools were developed recently to be complementary markers for (COI) DNA barcoding.
