09/05/2008 Exploring SA's vibrant biodiversity on the web

The sight of a spider in one’s home elicits varied responses but for many the immediate questions that spring to mind are “will it bite?”, “is it poisonous?”, “will it kill me?” To answer such questions, one needs to know the name of the spider and these days people expect the internet to provide such information. Iziko Museums of Cape Town’s Biodiversity Explorer website (http://www.biodiversityexplorer.org) provides such information and currently the spiders section is by far the most popular. Those who don’t find the answer to their spider query on this site are able to e-mail local expert Norman Larsen (who wrote the spiders pages and who is an Honorary Associate of Iziko) and get an answer. Norman receives a constant stream of queries, usually accompanied by digital images, ranging from requests for identifications through to desperate pleas for help from people who believe they have been bitten by a spider (it is often the case that a spider was not the cause).

Biodiversity Explorer ambitiously aims to cover all biodiversity in southern Africa from viruses and bacteria through to mammals. Inevitably, it is impossible to cover every species, so the focus is on featuring organisms that people want to know about. Hence, the sections of the website on spiders, scorpions, birds and mammals are quite far advanced and for the plants there is a particular focus on plants one encounters in everyday life such as garden plants, domesticated plants and weeds. The real fun starts in showing the ecological relationships between organisms. Hence, a page on the Morning Glory creeper (Ipomoea) links to the Fool’s gold beetle (Aspidomorpha), which in turn links to the parasitic wasp that parasitizes the pupa of this beetle.

The website was first launched eight years ago, on International Museum Day (18 May 2000), and has been steadily growing in content and profile since then. It has recently undergone a major revision and this year’s International Museum Day serves as an opportunity to launch this new version. It contains over 5000 web pages and over 4000 images. There are also two large companion sites to Biodiversity Explorer, one on the wasps of Africa (http://www.waspweb.org) with over 4600 pages and 4200 images, and the other on figs and fig wasps of the world (http://www.figweb.org) with over 1250 pages and 1400 images.

The International Council of Museums has this year set the theme for International Museum Day of “Museums as agents of social change and development”. One fundamental way in which museums fulfill this role is through education, not only through the educational experience of a museum visit, but through information provided in publications and websites. Gaining knowledge is empowering and isn’t so much about learning facts but rather about understanding processes and relationships. The internet provides a wonderful mechanism for showing relationships, which Biodiversity Explorer has exploited to the full.

Understanding the interconnectedness of life includes understanding the numerous relationships between humans and other organisms. It might come as a surprise to some that there are literally hundreds of species of bacteria living in our guts, in our mouths and on our skins little mites live in the hair follicles of our eyebrows!), most of them beneficial or inconsequential to our existence. Whether we like it or not, we are immersed in biodiversity and in our own interests, we need to understand and appreciate the life that lives in us, on us and around us.
