title: School Improvement Trajectories in Chile: a case study

description: Abstract: Progress in educational improvement research has generated consensus about the need to pay closer attention to the context within which it develops as well as to the multiple levels and participants involved in it. Within that analytic framework, a study was conducted to identify how the improvement trajectories experienced by schools can help understand their current scenario of strengths and weaknesses. Eight case studies were carried out in different types of Chilean schools, considering their socioeconomic and academic achievement characteristics. First, this study assessed the presence of educational improvement attributes in the schools. Following this, in-depth analyses of the trajectories of the four schools that attained the highest scores in the assessment were conducted. With the results obtained, an explanatory model was generated to describe the educational improvement trajectories of the schools that were analyzed. This model involves three stages (bring order; achieve organization, and improve teaching-learning), each of which includes one main process.

title: Teaching Identities in an Elite State School in Portugal

description: Abstract: This article applies Claude Dubar’s thesis to discuss the professional identities of eight teachers at a state school in Lisbon. In this case study, carried out in 2017-2018, the data collection involved life story interviews and questionnaires around social, economic and cultural issues. The analysis of biographical identity shows a trajectory of teachers who studied in state schools, who considered themselves dedicated and demanding, and who have had a solid academic background in their professional development. Identity for the others shows that the group is seen as active and devotedial by the community and has developed personal styles of teaching. The relational identity reveals a teaching exercise focused on educating young people from the upper-middle class to higher education.

title: Conservation of crop genetic resources in Brazil in the context of the target 9 of the Global Strategy for Plant Conservation

description: Abstract Cultivated species, on which humankind depends for survival, have been created by farmers that have crossed and selected wild plants and developed landraces. Early in 20th century, the theory of Centers of Origin of Cultivated Plants was proposed by Vavilov. He also warned the world about the loss of plant genetic diversity due to the dominance of a small number of genetically similar crops, a fact that help starting a movement for the conservation of plant genetic resources. From this time, several strategies and institutions were established around the world to act in plant genetic resources (PGR) conservation. In Brazil, a remarkable player in PGR conservation, some institutions conserve several crop species as well as their wild relatives and other socio-economically valuable plant species. In this paper we present the status of PGR conservation in Brazil as well as initiatives and laws aiming at respecting, preserving and maintaining associated indigenous and local knowledge, in the context of the target 9 of the Global Strategy for Plant Conservation.

title: Meanings of School Opportunity for Youth of the Popular Classes in Rio de Janeiro

description: Abstract: In this article, we seek to analyze the senses of opportunity that poor young people from Rio de Janeiro attribute to the school and to understand if, for these young people, school and schooling have a value in the now and/or imagined later. A total of 51 youths participated in this research, being students in elementary schools, from two public municipal schools of Rio de Janeiro, with ages between 14 and 16. Three discussion groups were made in the format of workshops. In the analysis of the meanings of opportunity and the value attributed by young people to school, the intra and intergenerational relationships established in this space were focused and the imaginary relation that these young people have with what will come after school.

title: Production and international trade: challenges for achieving targets 6 and 11 of the Global Strategy for Plant Conservation in Brazil

description: Abstract Target 6 of the Global Strategy for Plant Conservation of the United Nations Convention on Biological Diversity states that by 2020 at least 75% of production lands in each sector will be managed sustainably, consistent with the conservation of plant diversity. Target 11 stipulates that by 2020 no species of the wild flora will be threatened by international trade. Both targets, therefore, are related to production, consumption and trade, which must be sustainable if the targets are to be achieved. Here we examine Brazil's progress in achieving these two targets. We focus on the three economic sectors of agriculture, cattle raising and forestry, which are historically responsible for most of the native-ecosystem conversion in the country and in South America. Brazil has set a number of innovative policies for moving these sectors towards a sustainable path. However, the country needs to put these policies into action to generate tangible results. The results of all efforts so far are mixed. Whereas ecosystem conversion due to the expansion of rural production and the volume of illegal international logging trade have been reduced significantly, the absolute number of hectares of native ecosystems converted into cropland, pastureland or planted forests remains high, especially in Amazonia and the Cerrado. In addition, the number of species threatened by illegal timber exploration remains high mainly in Amazonia and the Atlantic forest.

title: Vascular plant species of the floating vegetation rafts from the Río de la Plata (Argentina)

description: Abstract In South American rivers, Eichhornia crassipes and other floating plants intertwine and form floating rafts commonly known as "camalotales" which are especially abundant during flooding periods. During extraordinary floods, hectares of floating mats are drifted by the Plata Basin Rivers. In the Río de la Plata several reports suggest that many animal and plant species from subtropical latitudes colonizes the area through these large rafts. These episodes are very important from the economic point of view because they cause several troubles to navigation and other activities. On the other hand, benefits to biodiversity are conspicuous, and many authors consider this process vital to the Río de la Plata wetlands and forests. However, there is scarce knowledge about Eichhornia rafts plant species composition. With the aim of creating an exhaustive list of the flora of the Eichhornia rafts, we visited the Río de la Plata coast during a massive Eichhornia rafts arrival. Thirty-two plant species were recorded in three different plant assemblages: Eichhornia rafts sensu stricto, floating reeds (canutillares) and embalsados. In front of this unexpected we emphasize the need to include this phenomenon in regional biodiversity conservation plans.

title: Ecological parameters of fungi in Bromeliaceae in natural and cultivated ecosystems in Bahia

description: Abstract Between May/2015 and February/2016 a study was carried out to estimate the richness, frequency and fungal similarity associated with Bromeliaceae from three areas in the Bahia state: Serra da Jibóia (municipality of Santa Terezinha), Morro da Redenção (municipality of Campo Formoso) and Orquilândia Tropical (municipality of Camaçari). Three species of Bromeliaceae were selected by area: Alcantarea nahoumii, Vriesea bahiana, Aechmea sp. (Serra da Jibóia); Aechmea aquilega, Hohenbergia catingae, Tillandsia gardneri (Morro da Redenção) and Aechmea Victoriana, A. naohoumii, Neoregelia compacta (Orquilândia Tropical). For each plant species 10 individuals were selected and three leaves of each with symptoms or fungal signs were collected. In the laboratory, indirect isolation was performed, which consisted of disinfestation in alcohol 70%, NaOCl 1% and washing in distilled water of leaf fragments. A total richness of 19 genera distributed in 27 taxa was found in Orquilândia tropical the great species richness was obtained (17 taxa) and the other areas presented 14 taxa each. There was a low similarity between fungal communities in the studied plants: 16.6% to 50% - Serra da Jibóia, 33.3% to 58.8% - Morro da Redenção and 23.3% to 58.3% - Orquilândia Tropical. The study revealed a fungal diversity occuring in different species of bromeliads, both in natural ecosystems and in cultivated areas.

title: Integrating remote sensing and phytosociology of the Atlantic Forest to map a small continental island in southeastern Brazil: subsidies to protect the habitat of critically endangered species

description: Abstract Queimada Grande (QGI) is a small, legally protected island off the southeastern coast of Brazil that harbors two endemic and critically endangered herpetofauna species: the Golden Lancehead viper (Bothrops insularis) and a hylid frog (Scinax peixotoi); its vegetation, however, has been little studied. We integrated remote sensing and phytosociology of the Atlantic Forest on QGI to characterize the habitat of those two species and support their in situ conservation. QGI retains a mosaic of Atlantic Forest, rock outcrop and anthropogenic vegetation, including invasive alien species, and bare rock surfaces. Mature Atlantic Forest, the preferential habitat of B. insularis and S. peixotoi, currently covers ~28 ha (~50%) of QGI and shows very low tree richness and an oligarchic structure. The most important species are Guapira opposita, Rudgea minor and Aspidosperma australe. Anthropogenic formations cover ~9% of the island and do not seem to have expanded in recent years. Based on local conditions, we recommend permanent monitoring of QGI and the use of local tree species in projects to restore the habitat of those two endangered species.

title: Comparative wood anatomy of Ficus cestrifolia (Moraceae) in two distinct soil conditions

description: Abstract Wood anatomical traits respond to environmental variables and among them, soil has a direct impact on secondary xylem. This study compares the wood anatomy of two populations of Ficus cestrifolia occurring in two lowland formations of Southern Brazil (MAQ and SJS) with similar climate but different soil conditions. Wood samples were collected at breast height and prepared according to standard wood anatomy techniques. Soil samples were collected and subjected to a nutrient analysis. Wood was described quali and quantitatively. The qualitative wood anatomical features of both populations were similar. Some quantitative differences were observed. In MAQ area, the levels of macro- and micronutrients were higher than in SJS. Its population presented higher vessel frequency, thicker-walled fibers, and lower vulnerability index. SJS's population had longer fibers, wider rays and a higher ray frequency, and higher vulnerability index. This suite of characters indicates that the MAQ population has a safer and more efficient xylem structure for water conduction. Under the influence of similar climate and soil type, differences regarding wood anatomical traits found between the two populations of Ficus cestrifolia can thus be regarded as an ecological response to the micro-environmental soils nutrients composition.

title: Germination, initial development and morpho-anatomy of epiphytic Cactaceae

description: Abstract Epiphytic Cactaceae with ornamental potential are found in the Brazilian Atlantic Forest. Differences in the germination process and post-initial development among plant species are of interest in the production and establishment of seedlings. This study aimed to investigate the germination and post-seminal development in vitro, in water and agar, and the stem morpho-anatomy of adult individuals growing in the natural environment of Rhipsalis neves-armondii, R. teres and L. cruciform, occurring in Santa Catarina. Growth and development analyzes were determined by measurements of length, biomass, chlorophyll and carotenoid content. Anatomical analyzes of the hypocotyl and stem were obtained by cross - sections and parsimony using classical techniques. The development of seedlings in water and in agar, indicated that it is indispensable to increase nutrients, because the reserve substances were depleted until 60 days of cultivation. In agar, the seeds of R. neves-armondii did not germinate. Anatomical features of the hypocotyl of R. teres and L. cruciforme seedlings were similar. The stem of these species adult individuals also revealed a similar histological constitution. Cuticle thick and water-storage parenchyma verified in the hypocotyl of the seedlings and the stems of adult plants are xeric characteristics, important for water economy of these epiphytes that are protected of the solar irradiation by the phorophyte, but with limitation of water availability.
