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

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.

A new millipede of the genus Gonographis from an inundation forest near Manaus, Brazil (Pyrgodesmidae)

Gonographis adisi (Pyrgodesmidae, Diplopoda) is newly described from a blackwater inundation forest near Manaus, Amazonas, Brazil. The species is able to survive submersion of up to eleven months

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

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

The Protura (Insecta) of Brazil, especially Amazonas

26 species of Protura are now known from Brazil. Seven new species are described in the present paper, viz. Berberentulus becki, nelsoni, hagmannarum, ovei, Eosentomon curupira, proximum and caatingae. Eight species are redescribed, viz. Brasilidia tropica Nos., Brasilentulus huetheri Nos., Berberentulus tuxeni Nos. & Huether (which was desc¡ibed as a Gracilentulus), Berberentulus huetheri Nos., brailianus Nos., amazonicus Nos., Eosentomon huetheri Nos. and hoogstraali Nos.. Gracilentulus neotropi cus Nos. is synonymized with G.kenyanus (Cdé). The known distribution within Brazil is given for each species as well as its biotope and location within this. The Protura are best known from Amazônia where they are found preferabty in the terra firme forest in the uppermost 3 to 5 cm where the soil is humous and interwoven with fungous hyphae. - In connection with my earlier paper on Isoentomon (Tuxen 1975) an interesting picture of the Brazilian Proturan fauna looms up, the geographical implications of which will be given elsewhere

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

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

Este estudo trata do Programa Bolsa Floresta (PBF), um dos maiores programas de Pagamento por Serviços Ambientais (PSA) do mundo, com mais de 35 mil pessoas atendidas em 15 Unidades de Conservação Estaduais (UCs) do Amazonas. Seus objetivos visam: melhorar a qualidade de vida das populações tradicionais e promover a manutenção dos serviços ambientais providos pelas florestas, por meio do não desmatamento e degradação florestal

About the relationship between the zooplankton and fluctuating water levels of Lago Camaleão, a Central Amazonian várzea lake

A two-year study of the composition and abundance of the zooplankton was conducted in an Amazonian vãrzea lake, Lago Camaleão. Rotifers were dominant in terms of both species numbers and density. The extremely low standing-stock observed during the high water period is attributed to prevailing poor oxygen conditions and, during extreme floods, current. The species associations of rotifers also reflect the flooding regime and its consequences
