Abstract

The following list includes the names and affiliations of all reviewers that evaluated the submissions processed for Volume 10, 2015 of Revista Ambiente & Água, including manuscripts that were accepted and published in one of the four annual issues and also manuscripts submitted and rejected in 2015. It may therefore include the names of reviewers that completed their evaluations between September, 2014 and October, 2015. Several of the reviewers evaluated more than one manuscript.We are deeply indebted to all of them that voluntarily and anonymously spent their precious time to support the journal, and contributed immensely to the quality of the published articles. We gratefully acknowledge their professional work and outstanding product. Note: 1) Some of these reviewers evaluated more than one manuscript; 2) This list includes reviewers that evaluated submissions that were not accepted for publication, in addition to the ones that were published in 2015.As seen in Table 2, 27 reviewers are from international institutions abroad. This is an indication that the journal is gaining international acceptance and inclusion. ABSTRACTLand-use change in the Amazon basin has occurred at an accelerated pace during the last decade, and it is important that the effects induced by these changes on soil properties are better understood. This study investigated the chemical, physical, and biological properties of soil in a field under cultivation of soy and rice, and at an adjacent primary rain forest. Increases in soil bulk density, exchangeable cations and pH were observed in the soy field soil. In the primary forest, soil microbial biomass and basal respiration rates were higher, and the microbial community was metabolically more efficient. The sum of basal respiration across the A, AB and BA horizons on a mass per area basis ranged from 7.31 to 10.05 Mg CO 2 -C ha -1 yr -1 , thus yielding estimates for total soil respiration between 9.6 and 15.5 Mg CO 2 -C ha -1 yr -1 across sites and seasons. These estimates are in good agreement with literature values for Amazonian ecosystems. The estimates of heterotrophic respiration made in this study help to further constrain the estimates of autotrophic soil respiration and will be useful for monitoring the effects of future land-use in Amazonian ecosystems.Keywords: land use change, microbial metabolic quotient, seasonality.Propriedades físicas, químicas, e biológicas de solo sob cultivação de soja e em floresta adjacente na Amazônia RESUMOAs mudanças no uso da terra na bacia Amazônica têm ocorridas num ritmo acelerado durante a última década, e é importante que os efeitos dessas mudanças nos recursos edáficos sejam explicados. Este trabalho teve como objetivo investigar as propriedades físicas, químicas, e biológicas de um solo sob cultivo de soja e arroz, e um solo de floresta primária adjacente. O solo do campo de soja teve aumentos na densidade, cátions trocáveis, e pH. Na floresta primária a biomassa microbiana e a respiração do solo foram maiores, e a comunidade microbia...
