Stem xylem resistance to cavitation is related to xylem structure but not to growth and water-use efficiency at the within-population level in Populus nigra L.
Xylem resistance to drought-induced cavitation is a key trait of plant water relations. This study assesses the genetic variation expressed for stem cavitation resistance within a population of a riparian species, the European black poplar (Populus nigra L.), and explores its relationships with xylem anatomy, water-use efficiency (WUE), and growth. Sixteen structural and physiological traits re...
متن کاملCycling efficiency in humans is related to low UCP3 content and to type I fibres but not to mitochondrial efficiency.
The purpose of this study was to investigate the hypothesis that cycling efficiency in vivo is related to mitochondrial efficiency measured in vitro and to investigate the effect of training status on these parameters. Nine endurance trained and nine untrained male subjects (V(O2peak) = 60.4 +/- 1.4 and 37.0 +/- 2.0 ml kg(-1) min(-1), respectively) completed an incremental submaximal efficiency...
متن کاملWater-use efficiency of an old-growth forest in lower subtropical China
Carbon and water fluxes are key properties of ecosystem processes and functions. A better understanding of their temporal dynamics and coupling mechanism between these fluxes will help us improve ecosystem management for mitigation as well as adaption to future climatic change. From 2003 to 2009, carbon and water flux data were obtained by the eddy covariance method over an old-growth forest in...
متن کاملA Prescription for Old-Growth-Like Characteristics in Southern Pines
Recent interest in adding old-growth reserves conflicts with a projected increase in the demand for forest commodities. However, managing for old-grorvthlike characteristics may permit timber production from stands designed to be similar to primeval forests. A silvicultural strategy based on presettlement forest conditions is being tested on 120 ac of mature loblolly (Pinus taeda) and shortleaf...
متن کاملGrowth Is Good, but Is Not Enough to Improve Nutrition
While it is generally agreed that growth is a necessary precondition for reducing poverty, relatively little is known about the relationship between economic growth and nutrition and, hence, how economic policies can be leveraged to improve nutrition. This chapter argues that growth is good, but is not enough to improve nutrition. During the early stages of development, growth helps reduce the ...
