Is it, or is it not, a Stegodyphus lineatus?
By Ofri Ilani
Israel is home to hundreds of kinds of spiders, but far fewer arachnid lovers. This is not only because most people are disgusted by spiders, or are quite indifferent to them. It seems the study of arachnids is a complicated and difficult hobby; only a small group of experts is able to identify spiders.
Efrat Gavish, 30, who is writing her doctorate on spiders at Ben-Gurion University, is one such expert. Gavish has been interested in eight-legged creatures and their world since she was a child.
"I grew up in Arad, which is a paradise for insects in general and spiders in particular," says Gavish. "Spiders are fascinating creatures, because, among other reasons, of the variety of ways in which they hunt."
One problem is that, until now, no comprehensive guide to spiders existed in Israel. Gavish says that students who wanted to identify spiders had to capture them and send them to experts to be identified. For a few years now, Gavish has been compiling a broad database on Israeli spiders. Last month, she launched it on the "Spiders in the Web" Web site (http://spiders.gois.co.il).
"There is information on spiders in Israel," explains Gavish, "but the purpose of the site is to make this information accessible, so that anyone interested can learn more about the spiders he sees."
In order to determine a spider's species, it must be examined with a magnifying glass. First, one has to differentiate between spiders with six eyes and spiders with eight eyes. Then one has to check if the eyes are arranged in two, three or more rows. Thus visitors to the site can progress from one stage of identification to the next, and finally ascertain whether the spider is a Stegodyphus lineatus, for example, or a Thomisus onustus.
Over the past year, a number of Israeli online guides have been launched, providing information and offering surfers a way of professionally identifying Israeli plants and animals. Behind these initiatives are a few nature buffs who are interested in sharing their knowledge with the vast community of Internet surfers.
There are a few good sites dedicated to Israeli birds, including two in English that are mainly designed for bird-watching tourists: birdingisrael.com, operated by the Center for Birdwatching at Kibbutz Lotan in the Arava desert, and israbirding.com. About six months ago, a Hebrew Web site - www.zapar.co.il - joined their ranks; the site posts new sightings of rare species, and is attracting a community of ardent bird-watchers.
These sites may be intended for experienced bird-watchers, but they include impressive photos that would interest even those who do not habitually wander about with binoculars around their necks. The sites also feature rare birds from distant places.
Increasing public awareness
In contrast, www.yardbirds.org.il focuses on birds that nest near our homes; those birds that most of us see on a daily basis. The goal of this site, set up by bird-watchers Doron Lahav and Shlomit Lifschitz, is to increase public awareness of birds in the urban environment, and to promote their protection. The site features simple instructions for attracting birds to back yards and pictures of birds in yards.
February 26 will mark the beginning of Backyard Bird Count Week, with the participation of surfers. Visitors to the site are invited to fill out the form available at the site, and the data will be collated so that estimates can be made regarding the bird species in various urban locations around the country.
Plant lovers have their own Internet guide, which is actually quite comprehensive. The guide, devoted to Israeli flora, is operated by the Hebrew University at http://flora.huji.ac.il, and is based on a database compiled by Prof. Avinoam Danin, one of Israel's top botanists.
This site was built by Udi Oron, a biologist and computer maven. The site currently offers information on 2,863 species of plants that grow in Israel and the surrounding area. Like most plant guides, the identification of a plant includes a series of questions on the different parts of the plant. Unlike most traditional plant guides, however, visitors at this site can start with whichever part of the plant they choose. Oron explains that the guide he built is one of the only online plant identification systems in the world.
"Our goal is to continue the project of the great botanists who once worked here, with the assistance of plant enthusiasts," says Oron. "We are the next generation of the guide."
