On Wednesday, June 10 from 8-10 am PST (5-7 pm Denmark time) via Zoom. The focus of this seminar will be Horseshoe crabs: Blood, trade and genes. Associate Professor Peter Funch, from the Aarhus University, Denmark, with assistance from biologists Stine Vestbo and Hanne Christiansen will guide our conversation.
There are four extant species of horseshoe crabs; one ranging along the eastern coast of North America, and three ranging in Asian waters, from India east to Indonesia, and from Indonesia north to Japan. Horseshoe crabs reside in shallow waters on the continental shelves, and utilize coastal and estuarine habitats for mating and spawning. While horseshoe crabs feed on invertebrates and plant material found in the sediment, they are themselves important prey for many migratory bird species. In some regions of Southeast Asia, horseshoe crabs are considered a delicacy and are fished and traded across borders for the purpose of consumption. However, the usage of horseshoe crab blood in the medical and pharmaceutical industries (extracts from the blood is used to test if equipment and products are free of bacterial contamination) makes these animals invaluable to humans, although it also seems to be the reason behind population declines. This seminar discusses how the future of horseshoe crabs is intertwined with their blood, genetics and unknown distributions, based on book chapters and primary natural science papers covering a variety of subjects.
