2007 article

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

Janowitz, G. S., Kamykowski, D., & Liu, G. (2007, August 10). Continental Shelf Research.

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

author keywords: continental shelf; dinoflagellate : behavior; modeling : population dynamics; west Florida shelf
topics (OpenAlex): Marine and coastal ecosystems; Marine Toxins and Detection Methods; Marine Biology and Ecology Research
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 article

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

Janowitz, G. S., & Kamykowski, D. (2006, May 22). Marine Ecology Progress Series.

By: G. Janowitz n & D. Kamykowski n

author keywords: model; population dynamics; dinoflagellate; behavior
topics (OpenAlex): Marine and coastal ecosystems; Marine Toxins and Detection Methods; Aquatic Ecosystems and Phytoplankton Dynamics
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 article

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

Burkholder, J. A., Eggleston, D., Glasgow, H., Brownie, C., Reed, R., Janowitz, G., … Springer, J. (2004, June 15). Proceedings of the National Academy of Sciences, Vol. 101, pp. 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
topics (OpenAlex): Coastal wetland ecosystem dynamics; Coastal and Marine Dynamics; Tropical and Extratropical Cyclones Research
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 article

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

Liu, G., Janowitz, G. S., & Kamykowski, D. (2002, January 1). Marine Ecology Progress Series.

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

author keywords: model; dinoflagellate; Gymnodinium breve; population dynamics; behavior; nutrients
topics (OpenAlex): Marine and coastal ecosystems; Marine Biology and Ecology Research; Marine Toxins and Detection Methods
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 article

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

Liu, G., Janowitz, G. S., & Kamykowski, D. (2001, January 1). Marine Ecology Progress Series.

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

author keywords: model; population dynamics; dinoflagellate; behavior
topics (OpenAlex): Marine and coastal ecosystems; Marine Toxins and Detection Methods; Aquatic Ecosystems and Phytoplankton Dynamics
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.
