A Horseshoe Crab (Limulus polyphemus) Demographic Study
… biomedical company that bleeds horseshoe crabs (Limulus polyphemus) and utilizes their blood for biomedical purposes. We examined mortality rates of bled and unbled crabs by holding crabs in tanks for 2-week periods. We estimate average differential mortality between bled and unbled horseshoe …

LECTINS FROM THE HORSESHOE CRAB, LIMULUS POLYPHEMUS, REACTIVE WITH BACTERIAL LIPOPOLYSACCHARIDE
<p>The Limulus serum is capable of precipitating various components of the lipopolysaccharide molecule from R mutants of Salmonella minnesota. Precipitation-inhibition studies using 2-keto-3-deoxyoctonate (KDO) have supported the hypothesis that this acidic residue is the immunodeterminant group in …

Selection of Spawning Habitats by Horseshoe Crabs (Limulus polyphemus) along the Complex Connecticut Coast
<p>The Atlantic horseshoe crab (<em>Limulus polyphemus</em>) is a multiple-use resource that has recently come under environmental conflict. This research focused on the Long Island Sound population of horseshoe crabs and aimed to characterize the coastal habitats of Connecticut by various traits …

Reducing post-bleeding mortality of horseshoe crabs (Limulus polyphemus) used in the biomedical industry
… maintenance in vitro. Hemolymph volume of L. polyphemus was estimated over a representative size range of adults. Hemolymph volume expressed as a percentage of wet body weight was 25 ± 2.2% (mean ± S.D.) for males and 25 ± 5.1% for females. Mortality associated with blood extraction was …

Bycatch associated with a horseshoe crab (Limulus polyphemus) trawl survey: identifying species composition and distribution
Horseshoe crabs (Limulus polyphemus) have been harvested along the east coast of the United States since the 1800s, however a Fishery Management Plan (FMP) was only recently created for this species. To date, there have not been any studies that have attempted to identify or quantify bycatch in the …

Variability in the Firing of Nerve Impulses in Eccentric Cells of the Limulus Eye
… cell in the compound eye of the horseshoe crab, Limulus polyphemus. In Part I a theory is presented which accounts for the variability in the response of an eccentric cell to light. The main idea of this theory is that the source of randomness in the impulse rate is "noise" in the generator …

BIOMEDICAL POTENTIAL OF AMOEBOCYTE LYSATE FROM CARCINOSCORPIUS ROTUNDICAUDA AND TACHYPLEUS GIGAS
… lysates were comparable to commercial lysates of Limulus Polyphemus and Tachypleus tridentatus in terms of the total protein content and sensitivity of endotoxin detection. Protein concentration, however, did not appear to be an absolute indicator of lysate potency. Our preparations were proven …

Design and Model-based Approaches for Estimating Abundance of American Horseshoe Crab
The American horseshoe crab (HSC), Limulus polyphemus, is one of four species of horseshoe crabs found throughout the world, and the only one found in North America. It is an economically and ecologically important species throughout its native range from Maine to the Yucatan Peninsula. Harvested …

Bayesian Hierarchical Methods and the Use of Ecological Thresholds and Changepoints for Habitat Selection Models
Modeling the complex relationships between habitat characteristics and a species' habitat preferences pose many difficult problems for ecological researchers. These problems are complicated further when information is collected over a range of time or space. Additionally, the variety of factors …
