圖書描述

The four living species of horseshoe crabs face a set of growing threats to their survival, including the erosion and/or man-made alteration of essential spawning habitat, coastal pollution, and overfishing. Horseshoe crabs are 'living fossils', with a more than 200 million year evolutionary history. Their blood provides a reagent, known as Limulus amebocyte lysate or LAL, that clots in the presence of minute quantities of bacterial endotoxin; the LAL test is the state-of-the-art methodology used to ensure that pharmaceuticals and surgical implants are free of contamination. Horseshoe crabs are an integral part of the food web in coastal marine ecosystems, and their eggs provide essential food for shorebirds in the Delaware Bay estuary each spring.The commercial fishery for horseshoe crabs, which utilizes animals for bait, contributes to the economies of coastal communities. This book consists of papers presented at the 2007 International Symposium on the Science and Conservation of Horseshoe Crabs.
