2007 journal article

A three-dimensional wind and behaviorally driven population dynamics model for Karenia brevis

CONTINENTAL SHELF RESEARCH, 28(1), 177–188.

By: G. Janowitz n, D. Kamykowski n & G. Liu *

author keywords: continental shelf; dinoflagellate : behavior; modeling : population dynamics; west Florida shelf
TL;DR: Model results indicate that even for the relatively weak wind driven currents used in the simulation a non-quantized population can develop into two spatially distinct quantized populations in a period as short as 1 day where, for present purposes, a quantized population is one in which all cells are at the same stage of the cell cycle.

2006 journal article

Modeled Karenia brevis accumulation in the vicinity of a coastal nutrient front

MARINE ECOLOGY PROGRESS SERIES, 314, 49–59.

By: G. Janowitz n & D. Kamykowski n

author keywords: model; population dynamics; dinoflagellate; behavior
TL;DR: Comparison of results from the simulations indicated that chemotaxis can play an important role in frontal accumulation in Karenia brevis. (via Semantic Scholar)

2004 journal article

Comparative impacts of two major hurricane seasons on the Neuse River and western Pamlico Sound ecosystems

PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA, 101(25), 9291–9296.

By: J. Burkholder n, D. Eggleston n , H. Glasgow n, C. Brownie n, R. Reed n , G. Janowitz n, M. Posey n, G. Melia n ...

author keywords: estuaries; fisheries; resilience; volume delivery; water quality
MeSH headings : Animals; Disasters; Ecosystem; Eukaryota / growth & development; Fishes; Fresh Water; Models, Statistical; North Carolina; Regression Analysis; Seasons
TL;DR: The data support the premise that, in shallow estuaries frequently disturbed by hurricanes, there can be relatively rapid recovery in water quality and biota, and benefit from the scouring activity of these storms. (via Semantic Scholar)

2002 journal article

Influence of current shear on Gymnodinium breve (Dinophyceae) population dynamics: a numerical study

MARINE ECOLOGY PROGRESS SERIES, 231, 47–66.

By: G. Liu n, G. Janowitz n & D. Kamykowski n

author keywords: model; dinoflagellate; Gymnodinium breve; population dynamics; behavior; nutrients
TL;DR: The simulations demonstrate that G. breve's vertical migratory behavior tends to maintain population coherency despite the tendency of shear in the current to disperse the population, and that the shear can con- tribute to predictable cell cycling within the aggregation.

2001 journal article

A biophysical model of population dynamics of the autotrophic dinoflagellate Gymnodinium breve

MARINE ECOLOGY PROGRESS SERIES, 210, 101–124.

By: G. Liu  n, G. Janowitz n & D. Kamykowski n

author keywords: model; population dynamics; dinoflagellate; behavior
TL;DR: A new model of dinoflagellate diel migratory behavior and population dynamics is constructed using the Expanded Eulerian Method and it is shown that the reproduction strategy producing 2 daughters different in biochemical composition appears to be the one adopted by all or at least a large portion of the G. breve population in the experiment.
