Opis

Horseshoe crabs are "living fossils" that face growing threats. This book consists of papers presented at the 2007 International Symposium on the Science and Conservation of Horseshoe Crabs. It formulates plans for an international conservation program.

Biology and Conservation of Horseshoe Crabs, edited by Dr. John T. Tanacredi, Dr. Mark L. Botton, and Dr. David R. Smith, offers proceedings from a ground-breaking 2007 international symposium at Dowling College on the science and conservation of the horseshoe crab. Horseshoe crabs are well-known as "living fossils" with a geological history covering hundreds of millions of years and an ancestry reaching back 455 million years to the doorstep of the Cambrian. In spite of this longevity, each species now faces common and growing threats. Loss of essential spawning habitat due to erosion and shoreline development, coastal pollution, and overfishing all threaten horseshoe crab populations. Symposium participants from around the world gathered to share knowledge, present research results, and identify conservation challenges facing horseshoe crabs. This shared international knowledge and experience is presented here as a beginning in our collective efforts to conserve the world’s horseshoe crab species. Throughout the book, the reader will find results of new studies, and authoritative reviews on the science and conservation of all four of the world’s horseshoe crab species.
