Conditions for patchiness in plankton models.
Plankton patchiness in homogeneous physical environments is studied in this paper assuming that all involved populations disperse diffusively. A recent but powerful sufficient condition for the emergence of spatial patterns in models with any number of species is systematically applied to all food chain and food web plankton models and the result is rather sharp: all models explicitly containin...
متن کاملPlankton lattices and the role of chaos in plankton patchiness.
Spatiotemporal and interspecies irregularities in planktonic populations have been widely observed. Much research into the drivers of such plankton patches has been initiated over the past few decades but only recently have the dynamics of the interacting patches themselves been considered. We take a coupled lattice approach to model continuous-in-time plankton patch dynamics, as opposed to the...
متن کاملOn the origin of plankton patchiness
Plankton is the productive base of aquatic ecosystems and plays a major role in the global control of atmospheric carbon dioxide. Nevertheless, after intensive study, the factors that drive its spatial distribution are still far from being clear. The models proposed so far show very limited agreement with actual data as many of their results are not consistent with field observations. Here we s...
متن کاملThe Effects of Lagrangian vs. Population Dynamics on Plankton Patchiness Generation
The relative importance of Lagrangian and population dynamics on spatial pattern formation in the distribution of plankton near the ocean’s surface is investigated. Phytoplankton and zooplankton are treated as biologically interacting tracers that are passively advected by a divergence-free two-dimensional nonsteady velocity field. The time-dependence of this field is assumed to be quasiperiodi...
متن کاملModels of Plankton Biomass Spectra
The goal of this thesis is to study the causes and consequences of the size structure of marine planktonic ecosystems. To this end, a theoretical (continuous) size spectrum model was developed. Phytoplankton and zooplankton biomass is represented in the model as functions of their respective biomass size spectrums. Thus, the model allows the natural recovery of the continuous size spectrum for ...
