The nomenclatural status of the two "spiny-wristed" fiddler crabs: Uca spinicarpa Rathbun, 1900, and U. hesperiae Crane, 1975 (Crustacea: Brachyura: Ocypodidae).
A secondary homonymy is documented for Gelasimus [= Uca] tetragonon var. spinicarpa Kossmann, 1877 (a species from the Red Sea), and Uca spinicarpa Rathbun, 1900 (a species from the Gulf of Mexico). Although Kossmann's usage of the nomen spinicarpa has chronological priority, a reversal of precedence is required by Article 23.9 of the Code since Kossmann's use has not been applied as a valid na...
متن کاملIntraspecific Variation in Carapace Morphology Among Fiddler Crabs (Genus Uca) From the Atlantic Coast of Brazil
Isolation due to geographical barriers should promote genetic and morphological divergence among populations. Marine currents flowing in opposing directions along landmasses can constitute barriers that isolate populations dependent upon aquatic dispersal. The distribution of fiddler crabs (genus Uca) is regulated primarily by the oceanic transport of their planktonic larvae and by available ad...
متن کاملSemidome Building as Sexual Signaling in the Fiddler Crab Uca Lactea (brachyura: Ocypodidae)
During the mating season, males of the fiddler crab Uca lactea build semidomes of mud at the entrances of their burrows to which they attract females for mating in the upper intertidal zone. Related species build similar structures which either reduce aggression between neighboring males or attract sexually receptive females. Male U. lactea did not build disproportionately more semidomes as den...
متن کاملPhylogenetic patterns and the adaptive evolution of osmoregulation in fiddler crabs (Brachyura, Uca)
Salinity is the primary driver of osmoregulatory evolution in decapods, and may have influenced their diversification into different osmotic niches. In semi-terrestrial crabs, hyper-osmoregulatory ability favors sojourns into burrows and dilute media, and provides a safeguard against hemolymph dilution; hypo-osmoregulatory ability underlies emersion capability and a life more removed from water...
متن کاملDistribution, Population and Reproductive Biology of the Fiddler Crab Uca sindensis (Crustacea: Ocypodidae) in a Subtropical Mangrove of Pohl Area
Distribution, population and reproductive biology of Uca sindensis were studied in a subtropical mangrove of Pohl port in the northern Persian Gulf. Sex ratio, distribution, population structure, handedness (evenness), diameter burrow, breeding season and fecundity were investigated. Ten 0.5 m2 quadrates were randomly sampled during low tide periods from October 2009 to September 2010.A total o...
