Title: | Sustained plankton blooms under open chaotic flows |
Authors: | Hernández-García, Emilio CSIC ORCID ; López, Cristóbal CSIC ORCID | Keywords: | Predator–prey dynamics Chaotic flows Plankton blooms Excitability |
Issue Date: | 1-Sep-2004 | Publisher: | Elsevier | Citation: | Ecological Complexity 1(3): 253-259 (2004) | Abstract: | We consider a predator-prey model of planktonic population dynamics, of excitable character, living in an open and chaotic fluid flow, i.e., a state of fluid motion in which fluid trajectories are unbounded but a chaotic region exists that is restricted to a localized area. Despite that excitability is a transient phenomenon and that fluid trajectories are continuously leaving the system, there is a regime of parameters where the excitation remains permanently in the system, given rise to a persistent plankton bloom. This regime is reached when the time scales associated to fluid stirring become slower than the ones associated to biological growth. | Description: | 7 pages (final publisher version), 15 pages, 3 figures (attached post-print version).-- ArXiv pre-print available: http://arxiv.org/abs/nlin/0311054 | Publisher version (URL): | http://dx.doi.org/10.1016/j.ecocom.2004.05.002 | URI: | http://hdl.handle.net/10261/7486 | DOI: | 10.1016/j.ecocom.2004.05.002 | ISSN: | 1476-9840 |
