La historia del Vaupés: desde esta orilla

El Vaupés es un territorio mítico. Durante siglos esta región y su gente han sido motivo de múltiples leyendas que van desde las más insólitas historias, hasta las ya acostumbradas notas de curiosos, viajeros y etnógrafos. Vaupés es territorio, es río, es gente, es raudales y selva inhóspita. Ha sido también epicentro de una de las más dramáticas tragedias de intervención, asolamiento y destrucción protagonizada por el europeo y sus descendentes.El grupo de Estudios en Sistemas Tradicionales de Salud de la facultad de medicina de la Universidad del Rosario trabaja por la protección de los sistemas tradicionales de salud y el mejoramiento de la salud humana. Desde el año 1999, tuvo la oportunidad de encontrarse con médicos indígenas especialistas, kumús o payés del Vaupés. Un extraño encuentro que finalmente condujo a que el grupo acompañara a los indígenas de la zona del río Yapú en su proceso de unión, organización y protección cultural. En ese contexto empieza la descripción de la presente historia. Se ha querido recorrer, a través de fuentes secundarias, lo que se sabe de la llegada de los hombres occidentales a las tierras del Vaupés

Palynostratigraphy and sedimentary facies of Middle Miocene fluvial deposits of the Amazonas Basin, Brazil

Palynostratigraphic and sedimentary fades analyses were made on sedimentary deposits from the left bank of the Solimoes River, southwest of Manaus. State of Amazonas, Brazil. These provided the age-elating and subdivision of a post-Cietaceous stratigraphic succession in the Amazonas Basin. The Novo Remanso Formation is subdivided into upper and lower units, and delineated by discontinuous surfaces at its top and bottom. The formation consists primarily of sandstones and minor mudstones and conglomerates, reflecting fluvial channel, point bar and floodplain facies of a fluvial meandering paleosystem. Fairly well-preserved palynoflora was recovered from four palynologically productive samples collected in a local irregular concentration of gray clay deposits, rich in organic material and fossilized wood, at the top of the Nova Remanso Formation upper unit. The palynoflora is dominated by terrestrial spores and pollen grains, an d is characterized by abundant angiosperm pollen grains (Tricolpites, Grimsdalea, Perisyncolporites, Tricolporites and Malvacearumpollis). Trilete spores are almost as abundant as the angiosperm pollen, and are represented mainly by the genera Deltoidospora. Verrutriletes, and Hamulatisporis. Gymnosperm pollen is scarce. The presence of the index species Grimsdalea magnaclavata Germeraad et al. (1968) indicates that these deposits belong to the Middle Miocene homonymous palynozone (Lorente, 1986; Hoorn, 1993; Jaramillo et al., 2011). Sedimentological characteristics (poorly sorted, angular to sub-angular, fine to very-coarse quartz sands facies) are typical of the NOW Remanso Formation upper part. These are associated with a paleoflow to the NE-E and SE-E, and with a a entirely lowland-derived palinofloristic content with no Andean ferns and gymnosperms representatives. All together, this suggests a cratonic origin for this Middle Miocene fluvial paleosystem, which was probably born in the Purus Arch eastern flank and areas surrounding the crystalline. The palynological analysis results presented herein are the first direct and unequivocal evidence of the occurrence of Middle Miocene deposits in the central part of the Amazonas Basin. They also provide new perspectives for intra- and interbasin correlations, as well as paleogeographic and paleoenvironmental interpretations for the later deposition stages in the northern Brazilian sedimentary basins.

Braquiópodes devonianos da Bacia do Amazonas

O objetivo principal do presente trabalho é um estudo de caráter sistemático dos braquiópodes devonianos do Estado do Pará. O material paraense procede das Formações Maecuru, Ereré e Curuá. Aproveitou-se a oportunidade para revisar, também, os braquiópodes do devoniano da Colombia e Venezuela, que são tratados em apêndices neste trabalho. Vinte foram as espécies aqui assinaladas, as quais se distribuem pelos seguintes gêneros: Derbyina, Paranaia, Podolella, Tropidoleptus, Plicoplasia, Platyorthis, Amphigenia, Megastrophia, Protoleptostrophia, Discomyorthis, Acrospirifer, Mucrospirifer, Rhynchonella, Chonetes e Streptorhynchus. Vários destes gêneros são aqui identificados pela primeira vez. A comparação da fauna de braquiópodes do devoniano da Amazônia com a fauna Apalachiana dos Estados Unidos da América do Norte, sugere uma idade possível entre o Emsiano e Eifiliano, pela presença dos gêneros Amphigenia, Discomyorthis, Platyorthis, Plicoplasia. O presente trabalho constitui revisão compreensiva dos braquiópodes do devoniano da Bacia do Amazonas desde as publicações pioneiras de Rathbun, R. (1874; 1878).

Impactos ambientales en la microcuenca del río Parafuso, Amazonas oriental, Brasil

The research analyzed the environmental impact on hydrographic microbasin of Parafuso stream at Moju county, Para State, Amazon (Brazil). Data were obtained using digital images, documentary research, questionnaires, semi structured interviews, direct observation and participatory mapping. The results showed that anthropogenic actions and population growth without planning, associated with not planned use of the natural resources, has been caused intense degradation in the physical, biological and anthropogenic environment. The identified springs of the Parafuso stream are difuse, temporary and altered. The parafuso stream network was classified at second order. Most of the environmental impacts identified are adverse character, of great importance, high magnitude and long duration. The physical environment is the most impacted. The major impacting activity is the agriculture, with long term damage in the physical and biological environment, in order of magnitude and importance.

Nuevos chamanes en la Colombia accidentalizada

Este es un ensayo de una pequeña investigación de pregrado en donde se busca hacer una revisión bibliográfica de los temas asociados al chamanismo en la ciudad, o neochamanismo (como algunos lo llaman). Para este ensayo se muestra cómo puede estar funcionando la teoría en un caso etnografico concreto en un lugar de Bogotá. Este ensayo fue escogido para participar como ponencia , en 2009, en el Primer Foro Interno de Debate y Reflexión Escuela de Ciencias Humanas de la Universidad del Rosario

Dispersão de sementes de Vismia cayennensis (Jacq.) Pers. (Guttiferae) por morcegos na região de Manaus, Amazonas

We studied the feeding behavior of bats and their role in the seed dispersal of Vismia cayennensis in Manaus region, Amazonas State, northern Brazil. The characteristics of the plant and its fruits fit the chiropterocory syndrome. Five species of phyllostomid bats fed on Vismia fruits: Sturnira lilium, Sturnira tildae, Artibeus concolor, Carollia perspicillata and Rhinophylla pumilio. Apparently there is a relationship between flock foraging behavior and fruit availability in early night. The feeding behavior was similar for all bat species, varying with the presentation mode of the fruits. Seed germination tests and the distributional patterns of the plants indicate that bats are the dispersers of V. cayennensis.

Revisão do gênero Polyrhaphis Audinet-Serville (Coleoptera, Cerambycidae, Lamiinae)

Polyrhaphis Audinet-Serville, 1835, gênero de Lamiinae distribuído entre o México e América do Sul (excluindo o Chile e abaixo da latitude 35°S), é revisado. Três espécies novas são descritas: P. baloupae, procedente da Guiana Francesa; P. lanei, proveniente do Brasil (Amazonas e Pará); e P. peruana, do Peru. Duas espécies são sinonimizadas: P. testacea Lane, 1965 (= P. gracilis Bates, 1862) e P. paraensis [= P. papulosa (Olivier, 1795)]. É designado neótipo para P. papulosa. A autoria de P. horrida [= P. spinosa (Drury, 1773)] é discutida. Cerambyx armatus Voet (1778?) é considerado um nome inválido e Lamia armiger Schöenherr, 1817 (= Polyrhaphis armiger) o nome válido dessa espécie. Polyrhaphis spinipennis Laporte, 1840, é excluída da fauna da Colômbia. Novos registros de distribuição: P. argentina Lane, 1978, para o estado de São Paulo (Brasil); P. batesi Hovore & McCarty, 1998, para o Equador; P. belti Hovore & McCarty, 1998 para o Equador e Colômbia; P. gracilis Bates, 1862, para a guiana Francesa; e P. turnbowi Hovore & McCarty, 1998, em dúvida, para o Peru. É apresentada chave para as espécies do gênero.

Morphological analysis of three populations of Anopheles (Nyssorhynchus) nuneztovari Gabaldón (Diptera: Culicidae) from Colombia

Based on the results of comparative analyses of 1,039 specimens of several progenies of Anopheles nuneztovarifrom three localities in Colombia, eight costal wing spot patterns were observed. Patterns I and III were the most frequent: 77.96% and 11.36%, respectively. Using the diagnostic characters ratio of the length of the basal dark area of hind tarsomere II/length of hind tarsomere II, ratio of the length of the humeral pale spot/length of the pre-humeral dark spot, and the ratio of the length of the subcostal pale spot/length of the distal sector dark spot (DS-III2/Ta-III2, HP/PHD, SCP/DSD) approximately 5% of the adult females were misidentified as a species of Nyssorhynchus, different from An. nuneztovari. Approximately 5% of the specimens showed DS-III2/Ta-III2 ratio less than 0.25 (range 0.21 - 0.24), and among them 3.34% shared a HP/PHD ratio less than 1.50. Consequently, 1.52% of An. nuneztovari individuals can be misidentified as Anopheles oswaldoi. In those specimens with the DS-III2/Ta-III2 ratios higher than 0.25, 34.45% displayed SCP/DSD values greater than 0.50 and of these, 3.65% displayed HP/PHD values greater than 1.8. This combination of characters could lead one to misidentify samples of An. nuneztovari as Anopheles rangeli. Similarly, 2.43% of the females could be identified erroneously as either Anopheles aquasalis or Anopheles benarrochi. Individuals with a HP/PHD ratio greater than 2.0, could be misidentified as Anopheles trinkae, Anopheles strodei or Anopheles evansae. A distinct combination of diagnostic characters for An. nuneztovari from Colombia is proposed.

New Genotype of Dengue Type 3 Virus Circulating in Brazil and Colombia Showed a Close Relationship to Old Asian Viruses

Dengue type 3 genotype V viruses have been recently detected in Brazil and Colombia. In this study, we described another Brazilian isolate belonging to this genotype. Phylogenetic analysis including dengue type 3 viruses isolated worldwide showed that Brazilian and Colombian viruses were closely related to viruses isolated in Asia more than two decades ago. The characteristic evolutionary pattern of dengue type 3 virus cannot explain the close similarity of new circulating viruses with old viruses. Further studies are needed to confirm the origin of the new dengue type III genotype circulating in Brazil and Colombia.
