Modelling Microbial Nitrification and Exploring Nonlinear Mechanism by Dynamical Complexity
Nitrification, a crucial step in nitrogen cycle of ecosystems, is an important issue that attracts many attentions. In this research, the nitrification process is investigated by developing a new dynamical model which couples the kinetics of ammonia oxidation process and nitrite oxidation process. With the application of literature-based parameter values, the dynamical characteristics of nitrification process in aquatic and soil environments are studied. Stable coexistent equilibrium, periodic oscillations, as well as more complex nitrification dynamics, such as quasiperiodic and chaotic oscillations, are predicted in both environments under seasonal variations. The projected levels of ammonia and nitrite ions are similarly aligned with previously reported observations in natural ecosystems. By uncovering the dynamical complexity of nitrification process, this research can advance our comprehension of the nonlinear mechanisms underlying microbial nitrification in ecosystems.
期刊介绍:
The Chiang Mai Journal of Science is an international English language peer-reviewed journal which is published in open access electronic format 6 times a year in January, March, May, July, September and November by the Faculty of Science, Chiang Mai University. Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so.
