Fragmentos de um modelo: pequenas lavouras de café e acumulação de capitais. Franca/São Paulo 1890-1914

Este artigo versa sobre a importância da pequena cafeicultura no complexo cafeeiro entre 1890 e 1914. Discutimos aqui as relações de trabalho, as formas de financiamento e o modo como a pequena propriedade se insere neste universo. Utilizamos como fontes prioritárias os contratos de trabalho que envolviam a formação e/ou o trato de cafeeiros e as escrituras de dívidas hipotecárias, ambas lavradas nos Livros Cartoriais, fontes estas ainda não trabalhadas pela historiografia de forma mais sistemática. Desviamos nosso olhar para uma região marcada predominantemente pelas pequenas e médias fazendas produtoras de café, observando a dinâmica da acumulação em um período de expansão e de crise da cafeicultura.

Fecundity in Portunus spinimanus Latreille, 1819 (Crustacea, Brachyura, Portunidae) from Ubatuba, São Paulo, Brazil.

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.

Significado paleobiológico de agrupamentos (coloniais/ gregários) de Conularia quichua Ulrich, 1890 (Cnidaria), Formação Ponta Grossa, Devoniano (Pragiano-Emsiano), Bacia do Paraná, Brasil

The Conularia beds of the Ponta Grossa Formation (Devonian) of the Paraná Basin, southern Brazil, yield well-preserved specimens of Conularia quichua Ulrich and Paraconularia africana Sharpe. Many of these are preserved in life orientation. Also, one of the C. quichua specimens has five faces instead of four, providing additional evidence of a cnidarian affinity for conulariids. Conulariids occur in the Jaguariaíva Member (or Sequence B, transgressive system tract) containing several obrution deposits beneath marine flooding surfaces. Taphonomic data obtained from these beds show conclusively that both C. quichua and P. africana were epibenthic, sessile invertebrates originally oriented with their long axis perpendicular to the bottom and with their aperture opening upward. Of the 136 C. quichua specimens examined here, 125 occur isolated. Eleven of the C. quichua specimens collectively occur in five discrete clusters consisting of two or three specimens. All of the clustered specimens are fully inflated (exhibiting a rectangular transverse cross section) or slightly compressed longitudinally. In all of these specimens the apex is missing, and thus the problem of whether the clusters were clonal colonies or formed through preferential larval settlement cannot be resolved conclusively. However, in the single cluster consisting of three specimens, the specimens are oriented perpendicular to bedding, and thus they do not converge adapically. The three specimens are in contact with each other along the upper portion of their median region. These and the lack of any evidence of a sheet of budding stolons, suggest that this cluster was formed by preferential larval settlement. © Asociación Paleontológica Argentina.

Crédito e pequena cafeicultura no oeste paulista: Franca/SP 1890-1914

This article turns on the importance of the small coffee production in the coffee complex economy between 1890 and 1914. We argue here the relations of work, the forms of financing and the way as the small coffee production inserts itself in this universe. We use as priority sources the employment contracts that involved the formation and/or the treatment of coffee trees and the Writes of mortgage debts, both recorded in Notarial Books, documents not used by historiography in a systematical way. We turns our look for a region marked predominantly for small and the middle producing farms of coffee, observing the dynamics of the accumulation in a period of expansion and crisis of the coffee economy.

The megalopa stage of Portunus spinimanus Latreille, 1819 and Portunus gibbesii (Stimpson, 1859) (Decapoda, Brachyura, Portunidae) from the southeastern Atlantic coast of the United States

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.
