O texto parte da recente valorização da origem brasileira de Julia Mann, a matriarca da célebre família de escritores alemães, para discutir o tema da nacionalidade associado às categorias de gênero e raça. Discutimos a historicidade de categorias sociais e como estas determinam a auto-compreensão dos indivíduos. A sociedade alemã do século XIX caracterizou Julia como brasileira e, apesar do estigma que isto representava, ela utilizou-se desta origem exótica como forma de autocompreensão e resistência.

The object of this work was to study the conditions of embryo development and egg production in Portunus spinimanus Latreille, 1819 at Ubatuba region of Brazil. The number of eggs laid by 21 females in a range of size was determined. Eggs at 3 differ ent stages of embryonic development were measured P. spinimanus fecundity varied between 188,065 and 682,992, with an average of 429,676 +/- 157,203, for animals with a carapace width ranging from 56.2 to 86.6 mm. Between the initial and final stages of development there was an increase of 55.1% in egg diameter. The relatively high fecundity of P. spinimanus may be a strategy of the species faced with a high mortality rate in the larval phase; however this hypothesis should be tested.

Turnera diffusa Willd. var. afrodisiaca (Ward) Urb. (syn. T. aphrodisiaca) belongs to the family of Turneraceae and is an aromatic plant growing wild in the subtropical regions of America and Africa. It is widely used in the traditional medicine as e.g. anti-cough, diuretic, and aphrodisiac agent. This work presents a 3 min chromatographic analysis using low-pressure (LP) gas chromatography (GC)-ion-trap (IT) mass spectrometry (MS). The combination of a deactivated 0.6 m x 0.10 mm i.d., restrictor with a wide-bore CP-Wax 52 capillary column (10 m x 0.53 mm i.d., 1 mum) reduces the analysis time by a factor of 3-7 in comparison to the use of a conventional narrow bore column. Chromatographic conditions have been optimized to achieve the fastest separation with the highest signal/noise ratio in MS detection. These results allow fast and reliable quality control of the essential oil to be achieved. (C) 2003 Elsevier B.V. All rights reserved.

Brazil takes pride in its alleged lack of racial discrimination. These idealized racial relations are a construction of enlightened elites. This article analyzes one of the main cultural publications in the country in order to establish how European anthropological theories were interpreted by Brazilian intelectuals. In the reappraisal of the country proposed in the journal, the ethnic question was intensely discussed. A whitening of the population was generally perceived as a sort of magic solution to the contradictions in a multiracial, heterogeneous and rigidly hierarchic society. This natural process might be accelerated by an inflow of European immigration. The many expectations and tensions surrounding immigration were expressed in the construction of categories of desirable and undesirable immigrants. Thereof an ideal white country emerged, far away from the myth of racial democracy, which has not materialized in Brazilian society today.

We report Pelecitus helicinus Railliet & Henry, 1910 from 13 species of birds of 2 orders and 7 families, collected from the states of São Paulo and Mato Grosso, Brazil. All 13 constitute new host records for this nematode. In addition, we report the first record of Aprocta golvani Diaz-Ungria, 1963 from Brazil and Monasa nigrifrons (Bucconidae), as well as a number of other nematode records from Neotropical birds.

Studies on helminthfauna of marsh deer Blastocerus dichotomus Illiger, 1815 are rare, although helminthic diseases are an important cause of mortality in these animals. Fifteen male and female adult marsh deer from Sergio Motta's hydroelectric power station flooding area at Paraná River which died during the capture and quarantine procedures, between 1998 and 1999, were necropsied. Three trematodes species, Paramphistomum cervi, Balanorchis anastrofus and Zygocotyle lunatum, all belonging to superfamily Paramphistomoidea, were identified. The obtained trematodes were identified, counted and their respectives descriptors of infection were determined. All necropsied animals were infected by helminths. Paramphistomum cervi was the most prevalent species, while Zygocotyle lunatum was found in only one animal.

The identification of megalopae from plankton samples is difficult, because this larval stage is the least well known among crab larvae, unknown in some species and poorly described in others. Wild megalopa specimens of some swimming crabs (family Portunidae Rafinesque, 1815) were captured alive from neuston samples obtained during summer surveys near the coast of Charleston, South Carolina (U.S.A). For identification purposes, larvae were reared to the 8th juvenile instar. After reaching the 5th juvenile instar, the juvenile crabs exhibited morphological features suitable for identification to the species level. The specimens belonged to two species of Portunidae, Portunus spinimanus Latreille, 1819 and P. gibbesii (Stimpson, 1859). Their megalopae were described in detail and compared to other portunid megalopae known from the southeastern Atlantic coast of the U.S.A. Species-specific characters of portunid megalopae are the number of carpal spines on the chelipeds, the relative size of the sternal spines (7th sternite), the number of antennal flagellum segments, and the setation of mouthparts.
