Symposium: Issues in Spider Conservation
1998 Meeting of the Society for Conservation Biology
Macquarie University, Sydney, Australia
July 13-16, 1998

Rosemary Gillespie (University of Hawaii) and I (in a volunteer role for The Nature Conservancy) convened a symposium on "Issues in Spider Conservation" at the 1998 meeting of the Society for Conservation Biology as an effort to bring together researchers and conservation professionals to discuss the growing body of knowledge related to spider conservation.

There is a list of participants below and all paper abstracts are available here.



Symposium Description

Like many invertebrates, spiders have traditionally received relatively little attention from the conservation community. With only 35,000 of an estimated 170,000 species described and relatively sparse distribution and abundance information available for much of the fauna, conservation needs may be difficult to grasp. However, a growing number of independent efforts to characterize the ecological value of spiders, document threats to spider diversity, and develop effective conservation programs are taking place around the globe. This symposium provided one of the first conservation-focused forums for sharing and synthesis of this growing body of knowledge.

Fourteen speakers from across the globe presented papers that served to increase the awareness of spider conservation issues in the general conservation community and improve communication between arachnological researchers and conservation professionals. Many topics relating to spider conservation were covered by the participants. The ecological role of spiders were highlighted, including techniques for measuring spider biodiversity. Several speakers demonstrated the usefulness of spiders as ecological indicators. Factors impacting spider populations, such as habitat loss and degradation, alien species, and collection pressures were discussed. Speakers from different continents outlined current recovery efforts for threatened species including legislation, habitat protection, captive breeding, and creative management techniques. Conservation challenges and important research needs such as population genetics and systematics were also discussed.

To further these goals, nine papers from the symposium will be published in a Special Issue of the Journal of Insect Conservation in December 1999.

Here is the list of symposium participants and their papers.
