Plant Thermoregulation: Energetics, Trait-Environment Interactions, and Carbon Economics.
Building a more predictive trait-based ecology requires mechanistic theory based on first principles. We present a general theoretical approach to link traits and climate. We use plant leaves to show how energy budgets (i) provide a foundation for understanding thermoregulation, (ii) explain mechanisms driving trait variation across environmental gradients, and (iii) guide selection on function...
متن کاملEthical School in Islamic Economics and Conventional Economics
In the present age, it is the age of economic crises and challenges to moral values. Today, with many moral schools, we are faced with the dos and don’ts of economic activities. On the one hand, the Islamic society needs a dynamic and developed economy, and on the other hand, it needs to consolidate and strengthen moral values in order to bring worldly and otherworldly happiness to people by ma...
متن کاملGlobal leaf trait relationships: mass, area, and the leaf economics spectrum.
The leaf economics spectrum (LES) describes multivariate correlations that constrain leaf traits of plant species primarily to a single axis of variation if data are normalized by leaf mass. We show that these traits are approximately distributed proportional to leaf area instead of mass, as expected for a light- and carbon dioxide-collecting organ. Much of the structure in the mass-normalized ...
متن کاملRoot Branching Is a Leading Root Trait of the Plant Economics Spectrum in Temperate Trees
Global vegetation models use conceived relationships between functional traits to simulate ecosystem responses to environmental change. In this context, the concept of the leaf economics spectrum (LES) suggests coordinated leaf trait variation, and separates species which invest resources into short-lived leaves with a high expected energy return rate from species with longer-lived leaves and s...
متن کاملIntraspecific Trait Variation and Coordination: Root and Leaf Economics Spectra in Coffee across Environmental Gradients
Hypotheses on the existence of a universal "Root Economics Spectrum" (RES) have received arguably the least attention of all trait spectra, despite the key role root trait variation plays in resource acquisition potential. There is growing interest in quantifying intraspecific trait variation (ITV) in plants, but there are few studies evaluating (i) the existence of an intraspecific RES within ...
