Gut-associated microbial symbionts of the marsh fiddler crab, Uca pugnax
… with their host, the marsh fiddler crab, Uca pugnax. Furthermore, we assessed whether microbes benefit the host by contributing extracellular enzymes along the digestive tract. This is the first report of the eccrinid protists, Enteromyces callanassae and Enterobryus sp., inhabiting U. …

Gut-associated microbial symbionts of the marsh fiddler crab, Uca pugnax
… bacterial phylotypes. An exception was the U. pugnax hindgut phylotype most closely related to a phylotype identified from hindguts of the detritivorous shrimp Neotrypaea califomiensis. This finding suggests that detritivorous crustacean hindguts may provide an ecological niche for specific …

Comparison of Invasive and Non-Invasive Techniques for Measuring Fiddler Crab Density in a Salt Marsh
… and repeated excavation surveys to estimate Uca pugnax density in a salt marsh on Tybee Island, Georgia and estimated the cost and precision associated with each technique. Only single and repeated excavation accurately measured juvenile density, but these methods were more costly and caused …

Distribution of hydrocarbons in a salt marsh ecosystem after an oil spill and physiological changes in marsh animals from the polluted environment
… and survival of the intertidal fiddler crab, Uca pugnax, 5) on the relatively small ability of Uca to metabolize hydrocarbons, 6) on the presence of an inducible in vitro microsomal mixed function oxidase (MFO) enzyme system in the marsh minnow, Fundulus heteroclitus, 7) on the presence of …

Symbiotic Associations and Pathogenic Potential of Vibrios In the North Inlet Estuary
… flats and infaunal burrows of the fiddler crabs Uca pugnax (Bosc) and Uca pugilator (Smith); the feeding and burrowing actions of which, serve to ventilate and redistribute the marsh sediment. Bacteria belonging to the genus Vibrio are flagellated gram negative rods or curved rods common …

Impacts of Microenvironment On Distributions and Activities of Bacteria In A Salt Marsh Environment
… Infaunal burrows produced by the fiddler crabs Uca pugilator and Uca pugnax are abundant features of southeastern United States salt marshes. These water-filled burrows become significantly enriched in Vibrionaceae, and specifically Vibrio parahaemolyticus (4875 CFU mL-1), relative to creek …

Optimization of Culture Conditions for in Vitro Fertilization of the Microphallid Trematodes Gynaecotyla Adunca and Microphallus Turgidus
… from the green glands of fiddler crabs, <em>Uca pugnax</em>, excysted in 0.5% trypsin, washed and incubated in HBSS. Excysted worms were examined microscopically to determine sperm maturation time. The effect of different culture vessels and worm density on fertilization was tested. …

<em>In Vitro Cultivation</em> of the Microphallid Trematode <em>Gynaecotyla Adunca</em>
… second intermediate host, the fiddler crab <em>Uca pugnax</em>. Hunter (1952) reported that <em>G. adunca</em> only self-fertilize, however, offered no evidence to support this claim. I decided to test <em>G. adunca</em> adult worms to either confirm or refute whether this is true or not. I also …

Density, Shell Use and Species Composition of Juvenile Fiddler Crabs (Uca Spp.) at Low and High Impact Salt Marshes on Georgia Barrier Islands
… that show what affect this has on fiddler crabs (Uca spp.), a key species in salt marsh habitats. The present study looks at how human impacts are affecting juvenile fiddler crab densities, shell use, and species compositions. This study was conducted at 3 low and 3 high impact sites on Tybee and …
