Domínios do café: ferrovias, exportação e mercado interno em São Paulo (1888-1917)

Não obstante o peso decisivo das receitas geradas pelo café para os balanços financeiros das ferrovias paulistas entre 1888 e 1917, e a centralidade da atividade cafeeira na economia paulista de então, discute-se neste artigo a especialização relativa ao nível da produção verificada em São Paulo e a questão dos fretes das ferrovias neste cenário. Parte-se da ideia de que a cafeicultura, em seu desenvolvimento, demandava a diversificação de culturas agrícolas, pois as unidades básicas de produção - as fazendas de café - não se caracterizavam unicamente pela monocultura, sendo que os nexos entre uma produção voltada à exportação e outra voltada ao mercado interno davam-se nas relações de trabalho estabelecidas entre contratantes e contratados, e nas formas pelas quais os fazendeiros expropriavam aqueles que se subordinavam aos seus interesses. Verifica-se no caso estudado o aumento simultâneo das quantidades de café e de alimentos transportadas e transacionadas pela Cia. Mogiana nos marcos da periodização proposta; porém, percebe-se estreita dependência em relação à receita gerada pelo transporte de café. Aponta-se, ainda, a especialização absoluta ao nível do crédito e da circulação (transportes) que caracterizavam este complexo econômico.

LOSS OF HEMISPERMATOPHORES AND SEXUAL-BEHAVIOR OF TITYUS-BAHIENSIS (PERTY, 1834) (SCORPIONES, BUTHIDAE)

Male scorpions (Tityus bahiensis) that have been deprived of their hemispermatophores and hemispermatophore sheaths retain their ability to court females despite their inability to mate successfully. Although hemispermatophores usually regenerate rapidly in nature, no such regeneration occurred after experimental amputation.

LARVAL DEVELOPMENT OF THE SPIDER CRAB ACANTHONYX-PETIVERII EDWARDS,H.MILNE, 1834 (DECAPODA, MAJIDAE) IN THE LABORATORY

The larval development of Acanthonyx petiverii H. M. Edwards, 1834, was studied in the laboratory through eggs hatched from ovigerous females collected in Ubatuba, state of São Paulo, Brazil. The rearings were carried out in a climatic room with constant temperature (25 degrees +/- 1 degrees C) and salinity (34,5 parts per thousand). The larvae were maintained individually and the food consisted of Artemia nauplii. The larval development of A. petiverii consists of two zoeal stages and a megalopa. All the larval stages were drawn and described in detail. Tables include those presenting morphological characters that allow the identification of zoeae and megalopa of A. petiverii. A comparative study was realized with previously studied majid species that occur in southern and southeastern Brazil.

Larval development of Epialtus bituperculatus H. Milne Edwards, 1834 (Crustacea: Decapoda: Brachyura: Majidae) with comments on majid larvae from the southwestern Atlantic

The larval development of the spider crab Epialtus bituberculatus H. Milne Edwards which lives on rocky shores with algae such as Sargassum and Hypeneia, is described. Larvae were obtained from ovigerous females collected in Ubatuba, State of São Paulo, Brazil. Rearing was carried out at 24 ± 1°C, with an average salinity of 35%. Larval development consists of two zoeal stages and one megalopa. Zoeal development was completed in 9.5 days. Analysis indicated that zoeae of E. bituberculatus are very similar to those of E. brasiliensis Dana and Acanthonyx scutiformis (Dana). Differences noted between these species pertain to the setation of the carapace, maxillule and second maxilliped. The main morphological features useful for identification are presented together with a summary of features that characterize larvae of majid subfamilies in Brazil. A key for the identification of southwestern Atlantic majid zoeae to the family level is provided.

Bathymetric distribution and recruitment of the spider crab Libinia spinosa H. Milne Edwards 1834 in the Ubatuba and Caraguatatuba regions, northern coast of São Paulo, Brazil (Crustacea, Brachyura, Majoidea, Pisidae)

The objective of this study was to investigate the spatial and temporal distribution of Libinia spinosa H. MILNE EDWARDS 1834 on unconsolidated sublittoral bottoms in two regions off the northern coast of the state of São Paulo, and to analyze the influence of environmental factors on the occurrence of this species and observe the recruitment pattern of its young. Crabs were collected monthly (July 2001 through June 2003) at depths of 5, 10, 15, 20, 25, 30 and 35 In, from a fishing boat equipped with two double-rig nets. Samples of water and sediment were collected for analysis of environmental factors. A total of 2112 spider crabs was obtained (701 juveniles and 1411 adults). The highest abundance was observed at depths of 20 and 25 m, in both regions. These localities were characterized by substrate composed of very fine sand and silt-clay. In regard to the temporal distribution, juveniles and adults predominated in the summer and winter months respectively. From these results, one can infer that the distribution of L. spinosa is related to environmental factors favorable for its life cycle; sediment type is the factor which most strongly determines its presence. © E.
