    A new species of Anastrepha from Amazonia : with redescriptions of A. caudata Stone and A. hendeliana Lima (Diptera: Tephritidae)

    Get PDF
    Three species of Anastrepha from upper Amazonia are described or redescribed and illustrated. They are considered closely related and are placed in the A. caudata species group. Anastrepha caudata Stone 1942 is redescribed based on the holotype, the only known specimen. Its type locality is probably São Paulo de Olivença in Amazonas, Brazil, not the state or city of São Paulo as previously assumed. Anastrepha hendeliana Lima 1934, new status, is removed from synonymy with A. longicauda Lima 1934 based on specimens from Brazil (Amazonas and Rondonia) and Colombia (Caquetá). The female is described for the first time. Anastrepha brunnealata, n. sp., is described from specimens from Venezuela (Amazonas) and probably Peru (Loreto). Anastrepha longicauda Lima is placed in the dentata species group.Se describen o redescriben e ilustran tres especies de Anastrepha del Amazonia. Ellas están consideradas cercanamente relacionadas y las ubican en el grupo de especies caudata. Se redescribe Anastrepha caudata Stone 1942 basado en el holotipo, el único especimen conocido. La localidad tipo probablemente es São Paulo de Olivença en el Amazonas, Brasil, no el estado o la ciudad de São Paulo como se asumió anteriormente. Se remueve Anastrepha hendeliana Lima 1934, stat. n., de la sinonómia de A. longicauda Lima 1934 basado en especimenes de Brasil (Amazonas y Rondonia) y Colombia (Caquetá). La hembra es descrita por primera vez. Se describe Anastrepha brunnealata, sp. n., de especimenes de Venezuela (Amazonas) y probablemente Peru (Loreto). Se ubica Anastrepha longicauda Lima en el grupo de especies dentata

    A water level relationship between consecutive gauge stations along Solim\~oes/Amazonas main channel: a wavelet approach

    Full text link
    Gauge stations are distributed along the Solim\~oes/Amazonas main channel to monitor water level changes over time. Those measurements help quantify both the water movement and its variability from one gauge station to the next downstream. The objective of this study is to detect changes in the water level relationship between consecutive gauge stations along the Solim\~oes/Amazonas main channel, since 1980. To carry out the analyses, data spanning from 1980 to 2010 from three consecutive gauges (Tefe, Manaus and Obidos) were used to compute standardized daily anomalies. In particular for infra-annual periods it was possible to detect changes for the water level variability along the Solim\~oes/Amazonas main channel, by applying the Morlet Wavelet Transformation (WT) and Wavelet Cross Coherence (WCC) methods. It was possible to quantify the waves amplitude for the WT infra-annual scaled-period and were quite similar to the three gauge stations denoting that the water level variability are related to the same hydrological forcing functions. Changes in the WCC was detected for the Manaus-Obidos river stretch and this characteristic might be associated with land cover changes in the floodplains. The next steps of this research, will be to test this hypotheses by integrating land cover changes into the floodplain with hydrological modelling simulations throughout the time-series

    Relationships among catches, fishing effort and river morphology for eight rivers in Amazonas State (Brazil), during 1976-1978

    No full text
    For eight rivers in the Amazonas State (Brazil), it is shown that the annual number of fìshermen and dummy variables, which identify the rivers, explain 98.8 % of the landings at Manaus market. Partial correlation analysis suggests that only the most productive floodplains are actively sought by professional fishermen. Keywords: river ecology, floodplain fisheries, multiple regressio

    A complete checklist with new records and geographical distribution of the rove beetles (Coleoptera, Staphylinidae) of Brazil

    This paper presents the first comprehensive list of 2,688 species of Staphylinidae (Coleoptera) recorded from Brazil. The list is based on the taxonomic and ecological literature, and new records from some insect collections, and includes locality references for each species. In addition, Brazilian localities and the country-level distribution outside of Brazil are provided for each species. Brazilian localities are organized by state, and include the bibliographic reference and page number where each locality was reported. All localities are geo-referenced, organized by state, and listed in an Appendix.Este trabalho apresenta a primeira lista completa das 2.688 espécies de Staphylinidae (Coleoptera) registradas para o Brasil. A lista inclui todas as localidades citadas para cada espécie e baseia-se na literatura taxonômica e ecológica disponíveis. Cada localidade inclui a referência bibliográfica e o número da página onde foram citadas. Também são apresentados registros inéditos obtidos de algumas coleções de insetos. Além das localidades brasileiras são citados todos os países com ocorrência conhecida para cada espécie. As localidades brasileiras, listadas no Apêndice, estão organizadas por estado e georreferenciadas
