Zoothamnium duplicatum infestation of cultured horseshoe crabs (Limulus polyphemus) [PDF]

, 2015
An outbreak of the sessile peritrich Zoothamnium duplicatum in a pilot, commercial-scale Limulus polyphemus hatchery resulted in the loss of ∼ 96% (40,000) second/third instar larvae over a 61 day period.

A Random Forest Regression Model for Predicting the Movement of Horseshoe Crabs in Long Island Sound

, 2021
Developing models to predict animal movement patterns is an important area of study in ecology and wildlife management. Project Limulus, a community research program, has been tracking the movement of tagged American horseshoe crabs (Limulus polyphemus ...

History of horseshoe crabs

, 2022
This paper delves into the different purposes for which people have captured horseshoe crabs and examines how these harvests – and other human activities in the age of the Anthropocene – have propelled the decline of horseshoe crabs populations.

Effects of blood extraction on horseshoe crabs (Limulus polyphemus) [PDF]

, 2003
Horseshoe crabs (Limulus polyphemus) are caught by commercial fishermen for use as bait in eel and whelk fisheries (Berkson and Shuster, 1999)—fisheries with an annual economic value of $13 to $17 million (Manion et al.1).

Monocytes Derived From Human Pluripotent Stem Cells Engineered for Detection of Pyrogens

Cell Proliferation, EarlyView.
In summary, we have developed a monocyte‐based reporter system using hESC‐Mono for interrogating the NF‐κB signalling axis, a central pathway governing pyrogenic responses. Our platform enables rapid and dose‐dependent detection of both endotoxins (LPS) and non‐endotoxins (LTA and Zymosan).
