A Simple Plankton Model on JSTOR

The American Naturalist

Description: Since its inception in 1867, The American Naturalist has maintained its position as one of the world's premier peer-reviewed publications in ecology, evolution, and behavior research. Its goals are to publish articles that are of broad interest to the readership, pose new and significant problems, introduce novel subjects, develop conceptual unification, and change the way people think. AmNat emphasizes sophisticated methodologies and innovative theoretical syntheses—all in an effort to advance the knowledge of organic evolution and other broad biological principles.

Coverage: 1867-2015 (Vol. 1, No. 1 - Vol. 186, No. 3)

Moving Wall: 3 years (What is the moving wall?)

Moving Wall

The "moving wall" represents the time period between the last issue available in JSTOR and the most recently published issue of a journal. Moving walls are generally represented in years. In rare instances, a publisher has elected to have a "zero" moving wall, so their current issues are available in JSTOR shortly after publication.
Note: In calculating the moving wall, the current year is not counted.
For example, if the current year is 2008 and a journal has a 5 year moving wall, articles from the year 2002 are available.

Terms Related to the Moving Wall: Fixed walls: Journals with no new volumes being added to the archive.; Absorbed: Journals that are combined with another title.; Complete: Journals that are no longer published or that have been combined with another title.

Abstract

Data on plankton ecosystems in large enclosures are used as a basis for consideration of the role of deterministic and random processes in these systems. Using a simple model, it is proposed that the exclusion of random variations in predators can lead to greater extremes in the phytoplankton/herbivore populations in enclosures compared with those outside. These results depend on the relative rates of internal and exogenous changes, and comparisons are made with results for a forest ecosystem.
