“…But within the next 40 years, the world will need to increase crop yields dramatically and, thus, Cerrado and Amazonia will, again, face pressures for more land for agriculture. That was my speech in South Korea (Habermann 2012).…”

“…In my speech at that meeting, I defended initiatives for investigating genes of native species, whose functions are still unknown (Souza and Habermann 2012). Specifically, I showed that many woody plants native to the Brazilian savanna, which is locally named Cerrado (meaning closed vegetation), are able to grow on soils that are acidic and rich in aluminum (Al), and that some species of Vochysiaceae and Melastomataceae families accumulate more than 10,000 g of Al per leaf dry mass (Haridasan 2008).…”

“…Until recently, Cerrado areas used to be considered "unfit for farming", mainly because of the low soil fertility, with high concentration of Al and low pH in the soil. But fertilization and lime application has provided conditions for performing agriculture on these lands (Souza and Habermann 2012). In this direction, the annual area deforested for agriculture in the Cerrado is on a par with that in the Amazon (Lapola et al 2010).…”

“…The Brazilian Cerrado covers an area of more than 2 million km 2 and is the richest and most threatened savanna in the world [1]. Since the 1950s, it has suffered intense fragmentation due to the advancement of the agricultural frontier [2].…”

The Brazilian cerrado, a hotspot of biodiversity, has suffered intense fragmentation in the last decades with an associated increase in areas subjected to edge effects. Plant phenology may be influenced by abiotic changes induced by edge effects, such as increases in temperature and light. We studied the phenology of the guamirim (Myrcia guianensis, Myrtaceae) and its relation to local abiotic factors in a Brazilian cerrado area between 2005 and 2011, aiming to answer: (i) whether M. guianensis phenology differs between the edge and the interior and/or between cardinal orientations at the study site, given that environments facing east are lighter and warmer than environments facing south; and (ii) how microenvironmental factors influence the observed phenological patterns. We sampled 92 individuals in 36 transects (25m x 2m), distributed along the edge and in the interior (100m from the edge) of the east and south faces. Myrcia guianensis presented seasonal patterns of leafing and reproduction, but only reproduction was influenced by microenvironmental conditions. Individuals on the east edge-the warmest and driest environment with the most light-presented with the highest synchrony and intensity of reproductive phenophases, followed by the east interior, south interior and south edge. Flowering and fruiting onset and peak dates occurred around 20 days earlier on the east edge than the south face. Edge conditions, primarily cardinal orientation, and associated higher temperatures and light incidence influenced the reproductive phenology of M. guianensis and the onset of flowering and fruiting. We suggest that edges could be used to evaluate plant responses to the temperature increases predicted for future climate change scenarios.

“…The Brazilian savanna (Cerrado) is comprised of a mosaic of biomes, from savanna vegetation to gallery forests (Batalha, 2011;Pinheiro and Monteiro, 2010) that originally covered 21% of the Brazilian territory (Souza and Habermann, 2012). Because of human activities (mainly agriculture), the Cerrado has been drastically fragmented, and less than 34% of its original area still remains (Klink and Machado, 2005).…”

We developed linear equations to predict the leaf area (LA) of the species Styrax pohlii and Styrax ferrugineus using the width (W) and length (L) leaf dimensions. For both species the linear regression (Y=α+bX) using LA as a dependent variable vs. W × L as an independent variable was more efficient than linear regressions using L, W, L 2 and W 2 as independent variables. Therefore, the LA of S. pohlii can be estimated with the equation LA=0.582+0.683WL, while the LA of S. ferrugineus follows the equation LA=-0.666+0.704WL. Keywords:Brazilian savanna, Styracaceae, validation, regression analysis, linear models. Equações lineares para estimativa de área foliar de Styrax pohlii e Styrax ferrugineus ResumoForam determinadas equações lineares para estimar a área foliar (AF) de Styrax pohlii e Styrax ferrugineus utilizando dimensões do limbo foliar (C -comprimento, L -largura). O modelo linear (Y=α+bX), utilizando AF vs. C × L, foi mais eficiente que os modelos lineares utilizando C, L, C 2 e L 2 como variáveis independentes na determinação da área foliar de S. pohlii e S. ferrugineus. Assim, a AF de S. pohlii pode ser estimada pelo modelo AF=0,582+0,683CL e a AF de S. ferrugineus pode ser estimada pelo modelo AF=-0,666+0,704CL.
