Nitrogen-fixing (diazotrophic) microorganisms regulate productivity in diverse ecosystems; however, the identities of diazotrophs are unknown in many oceanic environments.
It is shown that the proposed control strategy is versatile and effective in implementing robust control for regulating productivity in the presence of model mismatch, model uncertainty and parameter variation.
Health institutions urgently need to regulate productivity and improve quality of care and the balance between the number of specialists and family physicians.
High recombinant protein productivity in mammalian cell lines is often associated with phenotypic changes in protein content, energy metabolism, and cell growth, but the key determinants that regulate productivity are still not clearly understood.
At precipitation levels typical of grasslands, soil water will be lower on coarse-textured than fine-textured soils, increasing water limitation of community productivity, and thus the importance of soil water increases in regulating productivity.
Coastal upwelling and other processes regulating ecosystem productivity and fish production in the Western Indian Ocean.
Similarly, Ghd8 plays a pleiotropic role in regulating grain productivity and heading date depending on its genetic background, which reveals a positive correlation between flowering time and grain productivity (Yan et al. 2010).
The MOD17 GPP algorithm does not have a winter dormancy function to regulate winter productivity [18].
Together, these results show that multiple grazers powerfully regulate the productivity and drought resilience of these intertidal grasslands and that heterogeneity in physical stress and consumer density can dictate when and where top-down forcing is important.
This is of crucial importance for lake ecosystems, where P is one of the most important factors regulating ecosystem productivity and sediment has a large storage of P compared to the water column (Wetzel 2001).
Most employers, however, continued to want to treat the bonus as a discretionary gift; after all, this custom of "remembering the workers" served them well to oversee and regulate workers' productivity as well as assuring their loyalty.
