Suitability of wild decapods from an alluvial valley in South America for human nutrition as derived by amino acid composition by Petean, Magali, Collins, Pablo, D’Alessandro, Maria Eugenia

“…When comparing decapod AA profiles with those from marine and freshwater crustacean and fishes used as food (giant river prawn, amazon river prawn, longarm river prawn, southern king crab, green tiger shrimp, speckled shrimp, tuna, sardine, hake, carp, trout, jundía catfish), the values of Leucine and Lysine in the decapods were found to be higher or equal. …”

A morphological and phylogenetic analysis of Ornithodoros marinkellei (Acari: Argasidae), with additional notes on habitat and host usage by Venzal, José Manuel, Nava, Santiago, Hernández, Ligia V., Miranda, Jorge, Marcili, Arlei, Labruna, Marcelo B.

“…More recently, this tick was reported in the Brazilian Amazon. Because some morphometric differences were observed between O. marinkellei larvae from Colombia and Brazil, it was proposed that further investigations were needed to assess whether the differences could be attributed to intra- or inter-specific polymorphism. …”

Genetic diversity of the INPA germoplasm bank of camu-camu (Myrciaria dubia [H.B.K.] McVaugh) using microsatellites markers (EST-SSR) by Rojas, Salvador, Clement Ch., Yuyama K., Nagao, Eduardo Ossamu

“…Due to the economic potential of camu-camu, a fruit with a high level of vitamin C production, the aim of this study was to estimate the genetic diversity using the molecular markers EST-SSR, to study the genetic variability of 139 accessions from 17 “camu-camu” materiales from different rivers in the Brazilian's Amazon region, preserved at the INPA (Instituto Nacional de Pesquisas da Amazônia Brasilera) Active Germoplasm Bank (BAG) of “camu-camu” in Manaus. …”

Nut Production in Bertholletia excelsa across a Logged Forest Mosaic: Implications for Multiple Forest Use by Rockwell, Cara A., Guariguata, Manuel R., Menton, M., Arroyo Quispe, E., Quaedvlieg, J., Warren-Thomas, E., Fernández Silva, H., Jurado Rojas, E.E., Kohagura Arrunátegui, J.A.H., Meza Vega, L.A., Revilla Vera, O., Quenta Hancco, R., Valera Tito, J.F., Villarroel Panduro, B.T., Yucra Salas, J.J.

“…Brazil nut (Bertholletia excelsa, Lecythidaceae) is one of the world’s most economically-important NTFP species extracted almost entirely from natural forests across the Amazon Basin. An obligate out-crosser, Brazil nut flowers are pollinated by large-bodied bees, a process resulting in a hard round fruit that takes up to 14 months to mature. …”
