Sediment microbiomes associated with critical habitat of the Juvenile American Horseshoe Crab; Limulus polyphemus
Plumb Beach, Brooklyn, New York in USA is an important horseshoe crab breeding and nursery ground that has experienced substantial anthropogenic influence, including pollution, erosion and subsequent restoration. Since little is known about the relationship between sediment microbial communities and juvenile horseshoe crab survival, next generation sequencing was used to characterize and compar...
متن کاملBlood Collection from the American Horseshoe Crab, Limulus Polyphemus
The horseshoe crab has the best-characterized immune system of any long-lived invertebrate. The study of immunity in horseshoe crabs has been facilitated by the ease in collecting large volumes of blood and from the simplicity of the blood. Horseshoe crabs show only a single cell type in the general circulation, the granular amebocyte. The plasma has the salt content of sea water and only three...
متن کاملDevelopmental ecology of the American horseshoe crab Limulus polyphemus
During spawning events, horseshoe crab eggs are released from the female’s oviducts, and fertilized by one or more males. Eggs are shaped by the female into discrete clutches deposited in nests at depths of 10−20 cm on intertidal estuarine beaches. Distinguishing between fresh eggs and the early developmental stages is obfuscated by the large amount of dense, opaque yolk. The first unambiguous ...
متن کاملProtecting Horseshoe Crab Habitat
Each spring adult horseshoe crabs migrate from deep bay waters and the Atlantic continental shelf to intertidal sandy beaches to spawn. Horseshoe crabs are an important food source for migrating shorebirds that feed on the eggs, for migrating fish that feed on the eggs and larvae and for Atlantic loggerhead turtles that feed on horseshoe crabs while using the Chesapeake Bay as a summer nursery ...
متن کاملHemocyanin of the Horseshoe Crab, Limzdus polyphemus
The high molecular weight hemocyanin found in the hemolymph of the horseshoe crab, Limulus polyphemus, is composed of at least eight different kinds of subunits. Ion exchange chromatography at high pH in the presence of EDTA yields five major zones, hemocyanins I to V, three of which are electrophoretically heterogeneous. The subunits have similar molecular weights, 65,000 to 70,000, and their ...
