Grand challenges in global change research and environmental science raise the need for replicated experiments on ecosystems subjected to controlled changes in multiple environmental factors. We designed and developed the Ecolab as a variable climate and atmosphere simulator for multifactor experimentation on natural or artificial ecosystems. The Ecolab integrates atmosphere conditioning techno...

Forest ecosystems may provide strong sources of nitrous oxide (N2O), which is important for atmospheric chemical and radiative properties. Nonetheless, our understanding of controls on forest N2O emissions is insufficient to narrow current flux estimates, which still are associated with great uncertainties. In this study, we have investigated the quantitative and qualitative relationships betwe...

background: the existing models of information technology in health sciences have full scope of betterment and extension. the high demand pressures, public expectations, advanced platforms all collectively contribute towards hospital environment, which has to be kept in kind while designing of advanced technological ecosystem for information technology. moreover, for the smooth conduct and oper...

Polymorphic variation of immune system proteins can drive variability individual responses. Endoplasmic reticulum aminopeptidase 1 (ERAP1) generates antigenic peptides for presentation by major histocompatibility complex class I molecules. Coding SNPs in ERAP1 have been associated with predisposition to inflammatory rheumatic disease and shown affect functional properties the enzyme, but interp...

The systematic application of the synthetic ecosystems approach to the design of multi-agent systems is supported by the use of a generic pheromone infrastructure as extension of the runtime environment of the software agents. Using this infrastructure, insect-like coordination mechanisms may be applied in software systems. This article proposes an analytic model for such a generic pheromone in...

Factors constraining the structure of food webs can be investigated by comparing classes of ecosystems. We find that pelagic ecosystems, those based on one-celled primary producers, have longer food chains than terrestrial ecosystems. Yet pelagic ecosystems have lower primary productivity, contrary to the hypothesis that greater energy flows permit higher trophic levels. We hypothesize that lon...

Agricultural ecosystems are dependent for their natural resources on originally natural ecosystems. Agricultural ecosystems are also served by natural ecosystems with ecosystem services. Livestock will play a more important role in the next millennium because of the rising demand for animal food in the developing countries. Structural changes in land use through intensification of mixed farming...
