1. Sampling technique affects the population structure assessments of fiddler crab Minuca vocator (Herbst, 1804) (Ocypodidae: Gelasiminae)
Abstract We examined how the sampling technique can affect the evaluation of Minuca vocator (Herbst, 1804) population structure. We used two sampling procedures: catch-per-unit-effort (CPUE) and quadrat technique (QT). Body size, size-frequency distribution, population density, juvenile recruitment rates, proportion of ovigerous females and sex ratio were co

2. Temporal distribution in the abundance of the fiddler crab Uca (Leptuca) uruguayensis Nobili, 1901 (Decapoda: Ocypodidae) from Garças River mangrove, Guaratuba Bay, southern Brazil
A study on the temporal distribution, sex ratio, reproductive period, recruitment of juveniles and size composition of individuals of the fiddler crab Uca (Leptuca) uruguayensis was carried out in a population living in the Garças River mangrove, Guaratuba Bay, Paraná State, Brazil. Eight square samples of 0.25 m² (0.50 m side) were obtained on a monthly

3. Relative growth in the fiddler crab Uca uruguayensis Nobili, 1901 (Brachyura, Ocypodidae) from Garças River mangrove, Guaratuba Bay, southern Brazil
A study on the relative growth was carried out in a population of the fiddler crab Uca uruguayensis from the mangrove of Garças River, Guaratuba Bay, Paraná State, southern Brazil. The dimensions analyzed were the length of the major chela (LMC) of males and width of the abdomen (AW) of females, because they are related to reproductive activities of waving

4. The fiddler crabs (Crustacea: Brachyura: Ocypodidae: genus Uca) of the South Atlantic Ocean
The taxonomy of the 11 species of fiddler crabs [Uca (Uca) maracoani (Latreille, 1802-1803), U. (U.) tangeri (Eydoux, 1835), U. (Minuca) burgersi Holthuis, 1967, U. (M.) mordax (Smith, 1870), U.

5. Macroecologia do gênero Uca (Crustacea, Decapoda): padrões de diversidade, distribuição e respostas às mudanças climáticas globais / Macroecology of the genus Uca (Crustacea, Decapoda): patterns of diversity, distribution and responses to global climate change
O gênero Uca é composto atualmente por 97 espécies, distribuídas mundialmente, ocupando ambientes costeiros marinhos, principalmente da região tropical. Diversos campos de pesquisa têm desenvolvidos trabalhos usando o gênero Uca como modelo, entretanto, atualmente o conhecimento científico sobre esse grupo apresenta-se disperso, além disso, estudos

6. Intraspecific variation in preserved specimens of the fiddler crabs Uca panacea and Uca pugilator (Decapoda: Ocypodidae)
The fiddler crabs Uca panacea Novak & Salmon, 1974 and Uca pugilator (Bosc, 1802) are closely related North American species that are sympatric along the north coast of Gulf of Mexico. Since U. panacea was described, there has been confusion in the identification these two species. Morphological differences between these two fiddlers have been pointed out in

7. Taxonomia, filogenia e biogeografia das espÃcies de caranguejos do gÃnero Uca Leach, 1814 (Decapoda: Ocypodidae) no Oceano AtlÃntico e PacÃfico Oriental
The genus Uca comprises about 94 species. In the present contribution, a taxonomic review of those species distributed in the Atlantic Ocean (21 in the Western Atlantic and 1 in the Eastern Atlantic) and along the Pacific coast of America (35 species) has been completed as well as a phylogenetic analysis and a Parsimony Analysis of Endemicity (PAE). The mate

8. Macroecology of the genus Uca (Crustacea, Decapoda): patterns of diversity, distribution and responses to global climate change / Macroecologia do gênero Uca (Crustacea, Decapoda): padrões de diversidade, distribuição e respostas às mudanças climáticas globais
Macroecology of the genus Uca (Crustacea, Decapoda): Patterns of diversity, distribution and responses to global change. The genus Uca, composed by 97 species, has a worldwide distribution on coastal marine regions, mainly in tropical environments. Many researches have used the genus Uca as a model of study, although the actual scientific knowledge about thi

9. Molecular phylogeny analysis of fiddler crabs: test of the hypothesis of increasing behavioral complexity in evolution.
The current phylogenetic hypothesis for the evolution and biogeography of fiddler crabs relies on the assumption that complex behavioral traits are assumed to also be evolutionary derived. Indo-west Pacific fiddler crabs have simpler reproductive social behavior and are more marine and were thought to be ancestral to the more behaviorally complex and more te

10. Characterization of a pigment-dispersing hormone in eyestalks of the fiddler crab Uca pugilator
A pigment-dispersing hormone (PDH) from eyestalks of the fiddler crab Uca pugilator has been purified by gel filtration, ion-exchange chromatography, partition chromatography, and reversed-phase liquid chromatography. Based on automated gas-phase sequencing and subsequent identification of carboxyl-terminal amide, we have assigned the primary structure of th
