Non-linear dynamics in marine-phytoplankton population systems

Population Dynamics of Phytoplankton

Non-linear Age-dependent Population Dynamics

where P( t ) is the total population at time t and 5 is the growth modulus. This law is clearly inapplicable to situations in which the population competes for resources (e.g., space and food), for in these situations 5 should depend on the size of the population: the larger the population, the slower should be its rate of growth. To overcome this deficiency in the Malthusian law, VERHULST [184...

Complex Systems And Non-Linear Dynamics

We discuss the origins and recent advances of the vast field of non-linear dynamics and complex systems. The main aspects of complex systems are illustrated with relevant examples and the connection with non-linear dynamics and chaos is presented. Since this is a truly interdisciplinary field of research, many applications in mathematics, physics, chemistry, biology and physiology are briefly c...

a new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot

abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...

Phytoplankton growth, microzooplankton grazing, and carbon cycling in marine systems

We present an analysis of the global impact of microplanktonic grazers on marine phytoplankton and its implications for remineralization processes in the microbial community. The data were obtained by an extensive literature search that yielded 788 paired rate estimates of autotrophic growth (m) and microzooplankton grazing (m) from dilution experiments. From studies in which phytoplankton stan...
