Flooding effects in Lithraea molleoides plants were studied. Young plants were kept under drained and flooded soil over a period of 35 days. For growth and development analyses, the length and diameter of stem and main root and the dry weight of roots, stem, and leaves were measured. For anatomical studies, sections of fresh and fixed roots, stem bases and leaves were made using standard procedures in vegetal anatomy. The stress reduced the dry weight increment of plants without causing the death of roots or the abscission of leaves. In the stem base, flooding induced the hypertrophy of lenticels and the increase of intercellular space and reduction lower starch contents, in the cortex. Plants flooded displayed greater percentage of cortical intercellular space in the secondary roots and lower investment in secretory structure formation in the stem base. It can be suggested that flooding reduced the recourses allocation to growth. These recourses could be used in morphological alterations, such as hypertrophied lenticels and increase of intercellular spaces, that could contribute to plants survival during stress period, probably, due maintenance of aerobic respiration.

This short article, a political chronicle, examines the meanings and political and ideological effects of a Internet petition that was created in February of 2009. Repúdio e Solidariedade (Repudiation and Solidarity) questioned the use of the term ditabranda [a conjunction of two terms, ditadura and branda - or soft dictatorship] disseminated by the São Paulo news daily Folha de S. Paulo to refer to the Brazilian military dictatorship, and manifested solidarity with two University of São Paulo (USP) professors and intellectuals known for their action in defense of human rights in Brazil. Obtaining over eight thousand signatures in a period of less than six weeks, the petition may be considered (as the extensive comments which it includes testify to) a relevant document in the struggle for the right to truth and justice regarding what really happened during the period of the Brazilian military regime (1964-1985). Perhaps its most relevant symbolic role is that of staking claims within an ideological struggle over the memory of 1964. In the center of these claims sits a banner with the old motto No pasarán. In other words, democratic and progressive sectors of Brazilian society that supported Repúdio e Solidariedade made it clear that they were not going to quietly accept falsified views of history that are an insult to the memory of those who struggled, were tortured and died in the struggle to redemocratize the country.
