Changing Global Perspectives on Horseshoe Crab Biology, Conservation and Management reports significant progress of scientific research on horseshoe crabs, including aspects of evolution, genetics, ecology, population dynamics, general biology and physiology, within the recent 10 years. It also highlights the emerging issues related to world-wide conservation threats, status and needs. The contributions in Changing Global Perspectives on Horseshoe Crab Biology, Conservation and Management represent part of an ongoing global effort to increase data and concept sharing to support basic research and advance conservation for horseshoe crabs.
