Gut-associated microbial symbionts of the marsh fiddler crab, Uca pugnax
… of their interactions 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., …

A Behavioral and Ecological Study of the Fiddler Crab UCA CRENULATA
… and behavioral activities of a population of fiddler crabs, Uca crenulatat located in the "Aqua Hedianda" lagoon in Carlsbad, California, is the subject of this study.</p> <p>Variations in environmental factors as well as seasonal behavioral changes cause an important fluctuation in the male …

Gut-associated microbial symbionts of the marsh fiddler crab, Uca pugnax
(cont.) 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 …

Burrowing Behavior of the Fiddler Crab <i>Uca panacea</i> in Relation to Food Availability
<p>Much of fiddler crab behavior is regulated by the tides and centers around their burrows. Field and laboratory studies were conducted to assess the effect of food availability on burrowing in the Gulf coast fiddler crab, Vea panacea. In the field, crabs were observed for droving behavior through …

Molecular Population Genetics of the Atlantic Sand Fiddler Crab, Uca Pugilator, Along the Atlantic Coast
<p>Author's abstract: The Atlantic sand fiddler crab, Uca pugilator, is an extremely abundant fiddler crab found along the eastern and Gulf coast of the United States. Fiddler crabs have a life cycle with an obligatory planktonic larval phase of 30-90 days, which might be expected to lead to …

Spatial, temporal and spectral properties of photoreceptor cells in the fiddler crab Uca pugilator (Bosc, 1802)
Uca pugilator are semi-terrestrial brachyuran fiddler crabs that inhabit inter-tidal sand and mud flats. They are social animals that rely exclusively on visual information during several of their behaviors that include mate choice, predator avoidance, burrow surveillance, courtship and territorial …

Comparison of Invasive and Non-Invasive Techniques for Measuring Fiddler Crab Density in a Salt Marsh
Quantifying the density of burrowing crabs is challenging, and several techniques have been developed to accomplish it, including burrow counting, visual surveys of surface-active crabs, and substrate excavation. These techniques have been compared in mangrove forests but not in a salt marsh, nor …

Density, Shell Use and Species Composition of Juvenile Fiddler Crabs (Uca Spp.) at Low and High Impact Salt Marshes on Georgia Barrier Islands
… are no studies 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 …

Correlating Behavior and Physiology of Sand Fiddler Crabs, UCA Pugilator
… internal energy stores, and behavior in the sand fiddler crab,Uca pugilator. Energy stores were quantified through determination of the condition of the hepatopancreas, an internal organ in crustaceans that houses nutrients used in growth and reproduction.</p> <p>In the first study, energy stores …

Factors affecting Wilson's Plover (Charadrius wilsonia) demography and habitat use at Onslow Beach, Marine Corps Base Camp Lejeune, North Carolina
… among three coastal habitat types (i.e. fiddler crab (Uca spp.) mud flats, beach front, and interdune sand flats) at Onslow Beach, Marine Corps Base Camp Lejeune, North Carolina, 2008-2009. I observed little difference between years in nest success (≥ 1 egg hatched), failure, and overall …

Exploring the Interface Between Macroorganisms and Microorganisms: Biochemical, Ecological, and Evolutionary Contexts
… secretions are explored for barnacles, fiddler crabs and blue crabs. Fluids of interest were secretions released during barnacle settlement and metamorphosis and those collected from living adult barnacles, fluids on fiddler crab sensory appendages including dactyl washings and buccal …

<em>In Vitro Cultivation</em> of the Microphallid Trematode <em>Gynaecotyla Adunca</em>
… glands of the 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 …
