In this study, the phototactic behavior of Daphnia magna was investigated as a possible bioindicator for the following 11 chemicals commonly found in the aquatic environment: benzo(b)fluoranthene, mercury (II) chloride, dimethoate, lindane, linuron, MCPA, TBTO, carbon tetrachloride, thiram, 2,4,6-trichlorophenol and arsenic trioxide. Phototactic response(More)
A pilot study of leaf outline morphometrics was carried out on populations of five species of Heteropsis located in the Reserva Florestal Adolpho Ducke near Manaus, Amazonas, Brazil: H. flexuosa (Kunth) G. S. Bunting, H. macrophylla A. C. Sm., H. spruceana Schott, H. steyermarkii G. S. Bunting and H. tenuispadix G. S. Bunting. The aim of the study was to(More)
The species of the genus Heteropsis, known throughout Brazilian Amazonia as “cipó-titica”, have long been the target of intensive commercial collection because of the valuable fibre which is made from their aerial roots. The fibre is widely used in regional craft manufacture and forms part of the extractive industry of the region, based on forest products.(More)
Ethanol production from steam explosion alkaline delignified bagasse was investigated by saccharification and simultaneous fermentation. Non delignified bagasse (ND) contained 25% lignin, and after alkaline delignification, materials with 6% (D1 - NaOH 1% w/v) and 12% (D05 - NaOH 0.5% w/v) lignin, respectively, were obtained. Ethanol production increased(More)
