Última Estabelecimento e desenvolvimento de Dalbergia miscolobium Benth. em duas fitofisionomias típicas dos cerrados do Brasil Central Acta Botanica Braz,Vívian S.; Kanegae,Mieko F.; Franco,Augusto C.. As formações savânicas do Brasil Central caracterizam-se por uma camada rasteira contínua, em que predominam gramíneas, entrecortada por uma camada de arbustos e árvores de densidade variável. Dalbergia miscolobium Benth. é uma leguminosa arbórea típica dos cerrados do Planalto Central. Este estudo examinou os efeitos da seca, disponibilidade de luz, herbivoria e fogo no estabelecimento e crescimento dessa espécie no campo sujo (estrato herbáceo contínuo com árvores e arbustos esparsos) e no cerrado sensu stricto, onde a vegetação arbustivoarbórea é mais densa. Mudas foram transplantadas nas duas fitofisionomias, sendo acompanhadas mensalmente as variações na altura, produção de folhas e percentagem da área foliar removida por herbivoria, ao longo de cinco...

J. Plant Physiol. Scholz,Fabian G.; Bucci,Sandra J.; Goldstein,Guillermo; Meinzer,Frederick C.; Franco,Augusto C.; Salazar,Ana. The objective of this study was to characterize and understand morphological and physiological variation in traits related to water economy, at the plant and stand level, along a gradient of tree density in a Neotropical savanna (Cerrado). Cerrado plots subjected to long-term fertilization and gallery forests were also included in the analysis to expand the axes of ecosystem variation. Consistent changes in stand level biophysical traits observed along the gradient of increasing tree density included a decrease in weighted-average wood density, and increases in leaf surface area per plant, leaf specific hydraulic conductivity, specific leaf area and stomatal conductance. A conceptual model of biophysical, morphological and physiological trait interactions...

J. Plant Physiol. Bucci,Sandra J.; Scholz,Fabian G.; Goldstein,Guillermo; Meinzer,Frederick C.; Franco,Augusto C.; Zhang,Yongjiang; Hao,Guang-You. We determined adjustments in physiology and morphology that allow Neotropical savanna trees from central Brazil (Cerrado) to avoid water deficits and to maintain a nearly constant internal water balance despite seasonal changes in precipitation and air saturation deficit (D). Precipitation in the study area is highly seasonal with about five nearly rainless months during which D is two fold higher compared to wet season values. As a consequence of the seasonal fluctuations in rainfall and D, soil water potential changes substantially in the upper 100 cm of soil, but remains nearly constant below 2 m depth. Hydraulic architecture and water relations traits of Cerrado trees adjusted during the dry season to prevent increasing water deficits and insure...

Ano: 2008 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1677-04202008000300007 The importance of evolutionary history in studies of plant physiological ecology: examples from cerrados and forests of central Brazil Braz. J. Plant Physiol. Hoffmann,William A.; Franco,Augusto C.. Studies that compare physiology, anatomy, and ecology across species have offered some of the best insight into adaptation and evolutionary constraints in plants. As a result, the comparative approach has become increasingly used in studies of plant physiological ecology. The high species diversity of Brazilian biomes provides many excellent opportunities for comparative plant ecophysiology, and could be better exploited for understanding the evolution of plant form and function. In this paper we emphasize the importance of considering phylogenetic information for the design and analysis of comparative studies, relying on examples from comparisons of woody plants from cerrado and gallery (riparian) forests. The use of congeneric species pairs, each... Tipo: Info:eu-repo/semantics/article Palavras-chave: Cerrado; Forest; Specific leaf area; Leaf area ratio; Phylogeny.
