2. Impact of local conditions and machine management on grape harvest quality
ABSTRACT: Since its inception approximately 50 years ago, the grape harvester has been one of the machines responsible for the expansion of viticulture in the world. In Spain, harvesters were introduced in the 1990s (there are now approximately 3,000 machines there as of 2017), while they were introduced in Brazil in 2010. Harvest mechanization requires spec

5. Dinâmica de crescimento de Cedrela odorata L. (Meliaceae) na Floresta Atlântica do Estado do Rio de Janeiro: fenologia, atividade cambial e dendrocronologia / Growth dynamics of Cedrela Odorata L. (Meliaceae) on the Atlantic Rain Forest of the State of Rio de Janeiro: phenology, cambial activity and dendrochronology
Along the 20th century, a few dendrochronological studies were developed with tropical species, according to the belief that variations of the climatic conditions on those regions werent regular and strong enough to induce an annual rate of radial growth. The researches on this topic in the last decades showed that the formation of annual growth rings in the

7. Controle alternativo do míldio e da antracnose da videira com extrato aquoso de cinamomo (Melia azedarach L.) / Alternative control of downy mildew and anthracnose of grape aqueous extract of chinaberry (Melia azedarach L.)
The objective of this study was to evaluate different concentrations of aqueous extract of chinaberry (Melia azedarach L.) on the control of downy mildew (Plasmopara viticola) and anthracnose (Elsinoe ampelina) of grapevines cvs. Isabel and Cabernet Sauvignon. For all experiments the aqueous extract of chinaberry was prepared by addition of fruit with seeds

9. Dinâmica populacional e efeitos de variáveis ambientais sobre a fauna de pequenos mamíferos em um fragmento de floresta com araucária no sul do Brasil
Natural populations of small rodents fluctuate continually over time and the population dynamics of any living organism are shaped by both intrinsic and extrinsic factors. Small mammals populations can show a continuum dynamic activity, ranging from stability to regular cycles of variable amplitude. The species dynamics is also known to be influenced by the
