Ostracoda (Crustacea) from the Archipelago of São Pedro and São Paulo, Equatorial Atlantic, with emphasis on a new Hemicytheridae genus

The present study is a further contribution to the systematic knowledge of the shallow water marine ostracodes from the Brazilian oceanic islands. A total of 14 species belonging to 10 genera and eight families is herein identified. One new genus and species are described and illustrated: Berguecythere insularis gen. nov., sp. nov. In addition to this new taxon, the abundant species Loxocorniculum tricornatum Krutak, 1971, widely distributed in recent sediments in the Gulf of Mexico, Caribbean, north and northeast of Brazil and the Rocas Atoll, along with the cosmopolitan tropical ostracode Triebelina sertata Triebel, 1948, were also identified at specific level. The remaining 11 species were left at the genus level, and should provide new species. Ecological, zoo- and paleozoogeographical aspects were also briefly discussed.

New species of Xestoleberididae (Crustacea, Ostracoda) from Archipelago of São Pedro and São Paulo, Equatorial Atlantic

Two new species of Xestoleberididae: Xestoleberis brasilinsularis sp. nov. and Xestoleberis machadoae sp. nov., both endemic to Archipelago of São Pedro and São Paulo, are described. The record of these shallow marine waters species from Brazilian oceanic islands represents an important contribution to the knowledge of the evolutionary history the species inhabit areas.

First report of Ascarophis Van Beneden, 1871: A. Brasiliensis n.sp. (Nematoda, Ascarophidinae) and Procamallanus (Spirocamallanus) Pereira/Annereaux, 1946 (Nematoda, Procamallaninae) in South America

Ascarophis brasiliensis recovered from the stomach of Trachinotus carolinus (L. 1766), is proposed as a new species and Procamallanus (Spirocamallanus) pereirai Annereaux, 1946 is redescribed from a new host: Paralonchurus brasiliensis (Steind., 1875). A. brasiliensis is more closely related to A. crassicolis Dollfus & Campana-Rouget, 1956, from which it differs mainly by the absence of cervical cuticular expansion and size of the eggs. The new species is also compared to A. cooperi johnston & Mawson, 1945 and A. girellae (Yamaguti, 1935) Campana-rouget, 1955. The validity of the proposed species is discussed.

Agronomia i agrònoms a la Reial Acadèmia de Ciències Naturals i Arts de Barcelona (1766-1808)

Aquest treball estudia l’activitat agronòmica de la Reial Acadèmia de Ciències Naturals i Arts de Barcelona durant el període que abasta des de 1766 fins a 1808. Se centra en l’anàlisi de la documentació generada per la Direcció d’Agricultura d’aquesta institució, fent èmfasi en l’estudi del perfil biogràfic i intel•lectual dels homes que hi van estar al capdavant, i en la producció científica que van arribar a dur a terme. El treball enumera i analitza les propostes tècniques per millorar l’agricultura que des d’aquesta corporació es van sotmetre a debat. En aquest sentit, es destaquen les aportacions en temes com la vinya, els nous conreus o el debat sobre la situació de la ramaderia al país.

Biomphalaria aff. tenagophila do Sítio Arqueológico do Corondo, São Pedro da Aldeia, RJ

O presente estudo levou-nos a identificar as conchas de planorbídeos provenientes do Sítio Arqueológico do Corondó, RJ, como Biomphalaria aff. tenagophila. O Sítio foi datado entre 3.000 e 4.000 anos (C-14). A localização dos restos conquiliológicos sugere transporte por parte dos caçadores-coletores que ocuparam a área. Medidas comparativas feitas entre as B. aff. tenagophila antigas e B. tenagophila atuais de regiões próximas, demonstraram que as primeiras são mais largas do que as últimas.

Otodistomum cestoides (Van Beneden, 1871) from two species of skates taken in chilean waters

Otodistomum cestoides (van Beneden, 1871) (Azygiidae: Digenea) is reported for the first time from Psammobatis scobina and Raja flavirostris. The skates were caught off the coast of San Antonio, Chile.

El largo viaje de Juan Preciado: propuesta de lectura de la novela Pedro Páramo desde la mitología nahua

Nuestro trabajo pretende abrir una nueva línea de análisis de la novela de Juan Rulfo Pedro Páramo que explore el arquetipo de la muerte que se esconde en el recorrido que realiza el protagonista de la novela, Juan Preciado, por el fantasmal pueblo de Comala, a través del mito nahua que narra el viaje del alma desencarnada al inframundo, al Mictlán

Infecção por Enterobius vermicularis em populações agro-pastoris pré-colombianas de San Pedro de Atacama, Chile

Enterobius vermicularis eggs were found in human coprolites collected from the archaeological site of San Pedro de Atacama, North of Chile, in occupational layers dated from 1,000 BC. Agricultures and herding were begining at this period of time in this region of South America. The paleoparasitological data amplifies the knowledge about the distribution of human oxyuriasis in Pre-Columbian America.

Venezuelan economic laboratory. The Case of the altruistic economy of Felipe Pérez Martí

Felipe Pérez Martí, who was the Venezuelan Minister of Planning and Development in the government of Hugo Chávez, proposes an economic model that he calls the altruistic economy or fourth way, which leads cooperative game theory to its logical extremes postulating a pure communism. Here we sustain that, first, it is impossible in the model of Pérez Martí to marginally allocate non-primary goods to those most in need or who most value them, facing a problem of defective economic calculation, and second, in order to achieve equality, he would have to replace his atomic local planners by a central planner, who would be unable to overcome the problem of imperfect and and incomplete information.

Comparative Analysis by Polymerase Chain Reaction Amplified Minicircles of Kinetoplast DNA of a Stable Strain of Trypanosoma cruzi from São Felipe, Bahia, its Clones and Subclones: Possibility of Predominance of a Principal Clone in this Area

Molecular characterization of one stable strain of Trypanosoma cruzi, the 21 SF, representative of the pattern of strains isolated from the endemic area of São Felipe, State of Bahia, Brazil, maintained for 15 years in laboratory by serial passages in mice and classified as biodeme Type II and zymodeme 2 has been investigated. The kinetoplast DNA (kDNA) of parental strain, 5 clones and 14 subclones were analyzed. Schizodeme was established by comparative study of the fragments obtained from digestion of the 330-bp fragments amplified by polymerase chain reaction (PCR) from the variable regions of the minicicles, and digested by restriction endonucleases Rsa I and Hinf I. Our results show a high percentual of similarity between the restriction fragment lenght polymorphism (RFLP) for the parental strain and its clones and among these individual clones and their subclones at a level of 80 to 100%.This homology indicates a predominance of the same "principal clone" in the 21SF strain and confirms the homogeneity previously observed at biological and isozymic analysis. These results suggest the possibility that the T. cruzi strains with similar biological and isoenzymic patterns, circulating in this endemic area, are representative of one dominant clone. The presence of "principal clones" could be responsible for a predominant tropism of the parasites for specific organs and tissues and this could contribute to the pattern of clinico-pathological manifestations of Chagas's disease in one geographical area.
