Journal ArticleDOI
Diurnal and seasonal variation in root xylem embolism in neotropical savanna woody species: impact on stomatal control of plant water status.
Jean-Christophe Domec,Fabian Gustavo Scholz,Sandra Janet Bucci,Frederick C. Meinzer,Guillermo Goldstein,Guillermo Goldstein,Randol Villalobos-Vega +6 more
TL;DR: Maximum daily stomatal conductance declined linearly with increasing afternoon loss of root conductivity over the course of the dry season, consistent with a transition from a disequilibrium between plant and soil psi induced by nocturnal transpiration to one induced by hydraulic redistribution of water from deeper soil layers.
Journal ArticleDOI
Coordination of leaf and stem water transport properties in tropical forest trees
Frederick C. Meinzer,David R. Woodruff,Jean-Christophe Domec,Guillermo Goldstein,Paula I. Campanello,M. Genoveva Gatti,Randol Villalobos-Vega +6 more
TL;DR: A prominent role is suggested for the buffering effect of C in preserving the integrity of xylem water transport in individuals of 11 lowland tropical forest tree species, suggesting a trade-off between maximizing water transport and minimizing the risk ofxylem embolism.
Journal ArticleDOI
Nutrient availability constrains the hydraulic architecture and water relations of savannah trees.
Sandra Janet Bucci,Fabian Gustavo Scholz,Guillermo Goldstein,Guillermo Goldstein,Frederick C. Meinzer,Augusto C. Franco,Paula I. Campanello,Randol Villalobos-Vega,Mercedes M. C. Bustamante,Fernando Miralles-Wilhelm +9 more
TL;DR: Despite being adapted to chronic nutrient limitations, Cerrado woody species apparently have the capacity to exploit increases in nutrient availability by allocating resources to maximize carbon gain and enhance growth.
Journal ArticleDOI
Constraints on physiological function associated with branch architecture and wood density in tropical forest trees.
Frederick C. Meinzer,Paula I. Campanello,Jean-Christophe Domec,M. Genoveva Gatti,Guillermo Goldstein,Randol Villalobos-Vega,David R. Woodruff +6 more
TL;DR: In this article, the authors examined how leaf and stem functional traits related to gas exchange and water balance scale with two potential proxies for tree hydraulic architecture: the leaf area:sapwood area ratio (A(L):A(S)) and wood density (rho(w)).
Journal ArticleDOI
Size-dependent mortality in a Neotropical savanna tree: The role of height-related adjustments in hydraulic architecture and carbon allocation
Yong-Jiang Zhang,Frederick C. Meinzer,Guang-You Hao,Guang-You Hao,Guang-You Hao,Fabian Gustavo Scholz,Sandra Janet Bucci,Frederico Scherr Caldeira Takahashi,Randol Villalobos-Vega,Juan Pablo Giraldo,Kun-Fang Cao,William A. Hoffmann,Guillermo Goldstein,Guillermo Goldstein +13 more
TL;DR: Size-related changes in hydraulic architecture, carbon allocation and gas exchange of Sclerolobium paniculatum (Leguminosae), a dominant tree species in Neotropical savanna of central Brazil, were investigated to assess their potential role in the dieback of tall individuals.
