The drive for greater productivity
resources in a world of increasing demand. Dwindling oil and gas reserves mean the days of accessing easy hydrocarbons are all but over. With the downturn in the economy, many companies are trying to boost productivity by implementing costsaving measures, increasing work efficiency and by being more environmentally friendly. Indeed striving to improve productivity and eco-efficiency may be the ...
متن کاملKey canopy traits drive forest productivity.
Quantifying the mechanistic links between carbon fluxes and forest canopy attributes will advance understanding of leaf-to-ecosystem scaling and its potential application to assessing terrestrial ecosystem metabolism. Important advances have been made, but prior studies that related carbon fluxes to multiple canopy traits are scarce. Herein, presenting data for 128 cold temperate and boreal for...
متن کاملFinancial Conglomeration: Efficiency, Productivity and Strategic Drive
Consolidation in the global banking industry has resulted in the emergence of financial conglomerates that conduct an extensive range of businesses with a group structure. To date, however, few studies have investigated the performance features of such groups. This study aims to extend the literature by evaluating the cost characteristics (scale, scope and x-efficiency), profit efficiency and p...
متن کاملSoil microbes drive the classic plant diversity-productivity pattern.
Ecosystem productivity commonly increases asymptotically with plant species diversity, and determining the mechanisms responsible for this well-known pattern is essential to predict potential changes in ecosystem productivity with ongoing species loss. Previous studies attributed the asymptotic diversity-productivity pattern to plant competition and differential resource use (e.g., niche comple...
متن کاملDoes productivity drive diversity or vice versa? A test of the multivariate productivity-diversity hypothesis in streams.
The idea that productivity regulates species diversity is deeply ingrained in the field of ecology. Yet, over the past few decades, an increasing number of experiments have shown that species diversity controls, rather than simply responds to, biomass production. These contrasting perspectives have led to a seeming paradox: Is diversity the cause or the consequence of biological production? Her...
