Quantitatively understanding the robustness, adaptivity and efficiency of cell cycle dynamics under the influence of noise is a fundamental but difficult question to answer for most eukaryotic organisms. Using a simplified budding yeast cell cycle model perturbed by intrinsic noise, we systematically explore these issues from an energy landscape point of view by constructing an energy landscape...

This article suggests that the fundamental haploid-diploid cycle of eukaryotic sex exploits a rudimentary form of the Baldwin effect. With this explanation for the basic cycle, the other associated phenomena can be explained as evolution tuning the amount and frequency of learning experienced by an organism. Using the well-known NK model of fitness landscapes, it is shown that varying landscape...

Benefiting from the rapid development of global economy, a growing number post-industry products spring up. In comparison to population in suburb, urban presents significantly increasing tendency. Undoubtedly, efficient lifestyle, convenient way traveling and industrial have caused irresistible threat damage nature. The soil desertification, saline-alkali land, forest degradation else environme...

Wetlands are very sensitive to ecosystem changes, so integrated analyses and modeling of their process dynamics as well as their interaction with other hydrologic and ecological components provide valuable information for impact assessment. However, since wetland processes are complex, research methods aiming to improve the understanding of wetland dynamics in a landscape perspective must compr...

Cultural landscapes are increasingly understood as something not merely to be protected. The European Spatial Development Perspective (ESDP) and the European Landscape Convention (ELC) as well as the new Concepts and Strategies for Spatial Development in Germany propose considering cultural landscapes also as a force to promote cooperative regional development. Common historical roots, special ...
