The Pacific Mole crab Emerita analoga is a filter-feeding crustacean inhabiting sandy beaches along the western coasts of North and South America. The tissues of E. analoga contain carotenoids, dietary pigments that are involved in crustacean cryptic coloration and egg development. Despite extensive study of its life history, little is known about how E. analoga is affected by parasitism, even though previous groups noted the presence of larval helminths in its body cavity. We examined parasite prevalence and intensity of the acanthocephalan Profilicollis altmani infecting E. analoga from Pismo Beach, California. We investiged the effects of parasite infection and body size on egg production as well as the effects of parasite infection, body size, season and reproductive condition on tissue carotenoids. We also analyzed P. altmani cystacanths for carotenoids to determine if parasite acquisition of host carotenoids was possible. Infection by P. altmani did not affect the carotenoid concentration or content of any E. analoga tissues. Egg mass production was also unaffected by infection. Crab body size was the only significant predictor of carapace and egg carotenoid concentration, while reproductive season significantly affected ovarian carotenoid concentration. P. altmani cystacanths contained carotenoids similar to those found in E. analoga tissues, but we could not determine if acquisition was purposeful or from a specific tissue. E. analoga esophagus tissue was analyzed for the first time during this study and contained predominantly astaxanthin.

Therefore, it verified political-strategic importance and wealth of resources Hispania territory used to offer, attracting Mediterranean colonizers who founded several colonial towns in order to settle at the peninsular territory. Through the phenomenon of colonization, trades and inter-ethnic contacts, Greco-Roman colonial towns have achieved great success and led Iberian Peninsula to a long process of cultural influences by both Hellenism and Romanization, culminating, thus, in Greek-Roman culture spreading in Hispania. Ancient colonial towns have registered Greco-Roman influences that has remained expressed via urbanism and architecture, legated to posterity mainly by its ruins of monuments and buildings found in situ. Process of Romanization was highlighted in this study based on analysis of archaeological, architectural and urban vestiges evidence of the capital of Province of Hispana Ulterior of Lusitania – the Roman colonial town of Emerita Augusta – during the High Roman Empire period. Characteristics that used to comprise a Roman colonial town can show how magnificent and influent this provincial town was then, besides revealing the importance of that culture in antiquity and their influence to the present. / Esse estudo analisa a trajetória da expansão da colonização greco-romana ocidental pelo Mediterrâneo, até chegar à Península Ibérica. Para tanto, verificou-se a importância política-estratégica e riqueza de fonte recursal que o território hispano oferecia, atraindo colonizadores mediterrâneos que se utilizaram da fundação de diversas cidades coloniais para se estabelecerem pelo território peninsular. Através deste fenômeno colonizador, das trocas comerciais e dos contatos interétnicos, as cidades coloniais greco-romanas alcançaram grande êxito e implicaram que a Península Ibérica sofresse um longo processo de influências culturais tanto do helenismo como da romanização, culminando portanto, na difusão da cultura grecoromana pela Hispânia. As antigas cidades coloniais registraram as influências grecoromanas que permaneceram expressas via urbanismo e arquitetura, legados à posteridade, principalmente, através de suas ruínas de monumentos e edifícios encontrados in situ. O processo de romanização foi destacado neste estudo a partir da análise de evidências de vestígios arqueológicos, arquitetônicos e urbanos da capital da Província Hispana Ulterior da Lusitânia, a cidade colonial romana de Emerita Augusta, em período do Alto Império Romano. Tais características que compunham uma cidade colonial romana podem apontar a magnificência e influência de uma cidade provincial em seu tempo, além de revelar a importância desta cultura na Antiguidade e também seus reflexos em período atual.

Foram estabelecidos três transectos na zona entre-marés, perpendiculares à linha d' água, cada qual dividido em cinco estratos, paralelos a linha d' água. De cada estrato foram retiradas quatro réplicas com um amestrador metálico de 0,04m2. A expectativa de vida das fêmeas de Emerita brasiliensis foi calculada em 10,3 e 8,0 meses, respectivamente, para o primeiro (93/94) e segundo anos (94/95). Para os machos este parâmetro foi estimado em tomo de 9 meses para os dois anos de estudo. A produção foi calculada utilizando-se os métodos de Hynes e de Crisp 3A, sendo estimada entre 15,589 e 12,378g(PSLC)m^-2a^-1 , para o primeiro ano amostral, e entre 53,326 e 47,534g(PSLC)m^-2a^-1 , para o segundo ano, sendo a produção do segundo ano, significativamente superior a do primeiro ano.

Three transects were established in the intertidal zone, perpendicular to the waterline, each divided into five strata parallel to the waterline. From each level, four replicates were taken using a 0.04 m2 metal sampler. The life span of Emerita brasiliensis females was calculated in 10.3 and 8.0 months for the first (93/94) and second (94/95) years, respectively. For the males this parameter was estimated around 9 months for the two years of study. The production was calculated by the methods of Hynes and Crisp 3A, and was estimated between 15.589 and 12.378g(AFDW)m^-2a^-1 for the first sample year, and between 53.326 and 47.534g(AFDW)m^-2a^-1 for the second year, which was significantly higher than the first year. For Emerita brasiliensis...
