The phytoplanktonic ways of life [PDF]

open access: yesNew Phytologist, 1991
summaryThe adaptations of phytoplankton to life in suspension in water are considered with particular reference to hydromechanical factors ranging from molecular motion to ocean currents. The smallest phytoplankton, the picoplankton (0.2–2.0 μm), are the best adapted to the physico‐chemical environment of the open waters of seas and lakes and, other ...

A Study of Phytoplankton Dynamics in Lake Fayetteville as a Means of Assessing Water Quality [PDF]

open access: yes, 1971
Phytoplankton community was analyzed for seasonal and vertical distribution in Lake Fayetteville. This northwest Arkansas reservoir maintains a stable water level and chemical input with a relatively constant, slow overflow.

Net phytoplankton and zooplankton in the New York Bight, January 1976 to February 1978, with comments on the effects of wind, Gulf Stream eddies, and slope water intrusions [PDF]

open access: yes, 1984
Results are given of monthly net phytoplankton and zooplankton sampling from a 10 m depth in shelf, slope, and Gulf Stream eddy water along a transect running southeastward from Ambrose Light, New York, in 1976, 1977, and early 1978.

Population growth and persistence in a heterogeneous environment: the role of diffusion and advection

open access: yes, 2008
The spatio-temporal dynamics of a population present one of the most fascinating aspects and challenges for ecological modelling. In this article we review some simple mathematical models, based on one dimensional reaction-diffusion-advection equations ...

Spatial dynamics of a nutrient–phytoplankton system with toxic effect on phytoplankton [PDF]

open access: yesMathematical Biosciences, 2015
The production of toxins by some species of phytoplankton is known to have several economic, ecological, and human health impacts. However, the role of toxins on the spatial distribution of phytoplankton is not well understood. In the present study, the spatial dynamics of a nutrient-phytoplankton system with toxic effect on phytoplankton is ...

Vertical distribution and composition of phytoplankton under the influence of an upper mixed layer

open access: yes, 2010
The vertical distribution of phytoplankton is of fundamental importance for the dynamics and structure of aquatic communities. Here, using an advection-reaction-diffusion model, we investigate the distribution and competition of phytoplankton species in ...
