WATERFootprint of wine chain: comparison between two case studies portuguese
Saraiva, Artur; Egipto, R.; Presumido, P.; Jorge, C.; Amaral, A.; Castro Ribeiro, A.; Ferreira, Albertina; Goncalves, A.; Grifo, Anabela; Oliveira, M.A.Water scarcity caused by climate change and its implications on grape production and quality have raised concerns among wine producers. The adoption of sustainable practices is now a goal of winemakers since the efficient use of resources allows them to reduce production costs. The WineWaterFootprint project evaluated the water footprint in the wine industry through the development of a methodology applied to t...
Reproductive ecology of phorid parasitoids in relation to the head size of leaf...
Farder-Gomes, C.F.; Oliveira, M.A.; Gonçalves, P.L.; Gontijo, L.M.; Zanuncio, J.C.; Bragança, M.A.L.; Pires, E.M.The leaf-cutting ant Atta sexdens Forel (Hymenoptera: Formicidae) is one of the most damaging agricultural pests in the Neotropics. Management strategies predominantly rely on the use of general insecticides. What is needed are more species-specific and environmentally friendly options. Parasitioids such as phorid flies (Diptera: Phoridae) may be one such option, but a greater understanding of the ecology of th...
Extracts of Ageratum conyzoides, Coriandrum sativum and Mentha piperita inhibit...
Morais, W.C.C.; Lima, M.A.P.; Zanuncio, J.C.; Oliveira, M.A.; Bragança, M.A.L.; Serrão, J.E.; Della Lucia, T.M.C.Leaf-cutting ants live in symbiosis with the fungus Leucoagaricus gongylophorus (Singer) Möller that grows in their nests. This fungus is the main nutritional source for these ants that provide conditions for its development. Although plant extracts of Ageratum conyzoides L., Coriandrum sativum L. and Mentha piperita L. are known to cause mortality in ants in the laboratory, their effects on L. gongylophorus ar...
Produção e valor nutritivo do capim-coastcross sob doses de nitrogênio e idades...
Oliveira, M.A.; Pereira, O.G.; Ribeiro, K.G.; Santos, M.E.R.; Chizzotti, F.H.M.; Cecon, P.R.Avaliaram-se a produção e o valor nutritivo do capim-coastcross (Cynodon dactylon) sob cinco doses de nitrogênio - 0, 100, 200, 300 e 400kg/ha.ano - e duas idades de rebrotação - 28 e 42 dias. Os tratamentos foram arranjados em esquema fatorial, em blocos ao acaso, com três repetições. A adubação com nitrogênio (N) foi parcelada em três aplicações, realizadas logo após os cortes. A densidade populacional de per...
Characterization of the sedimentary record of the AD1755 tsunami in the Martinh...
Cunha, Pedro; Andrade, César; Freitas, Maria; Dinis, Jorge; Martins, António; Costa, Pedro; Oliveira, M.A.; Buylaert, Jan-Pieter; Murray, AndrewThis study addresses the Holocene sedimentary succession at Martinhal coastal lowland (Algarve), a site recording the AD1755 Lisbon tsunami. Data on twenty-four short cores and sixteen trenches, retrieved from both the literature and new field work were combined to improve the stratigraphic resolution and lateral correlation of sedimentary units accumulated in this lowland. Four fining-upward depositional seque...
