Trend, seasonality, cycle, and irregular fluctuations in primary productivity at Lake Tahoe, California-Nevada, USA
@article{Jassby2004TrendSC, title={Trend, seasonality, cycle, and irregular fluctuations in primary productivity at Lake Tahoe, California-Nevada, USA}, author={Alan D. Jassby and Charles Remington Goldman and Thomas M. Powell}, journal={Hydrobiologia}, year={2004}, volume={246}, pages={195-203} }
Primary productivity has been measured routinely at Lake Tahoe since 1967, and a number of mechanisms underlying variability in the productivity record have now been identified. A long-term trend due to nutrient loading dominates the series. Seasonality also is prominent, apparently controlled by direct physical factors unrelated to the trophic cascade. A 3-yr cycle has been detected and several possible mechanisms are considered. Irregular fluctuations also are present, caused in part by…

WINTER PHYTOPLANKTON BLOOMS UNDER ICE ASSOCIATED WITH ELEVATED OXYGEN LEVELS 1
- Environmental Science
- 2002
Results suggest that the elevated levels of dissolved oxygen are associated with the dinoflagellate, P. aciculiferum, of Arrowwood Lake, and that this bloom was most likely the result of an excystment event rather than a general growth response.
A plea for more ecology in phytoplankton ecology
- Environmental ScienceHydrobiologia
- 2004
It is suggested that it is advantageous to tackle eutrophication from the perspective of general ecology, rather than from a specifically planktonic orientation, and useful general ecological tools, for example, time series and assembly-rule studies, can be used.

This model of two species competing for two resources in a spatially nonuniform environment based upon the experience with phytoplankton competing for nutrients in lakes and the ocean shows much more variable behavior in space and time than the usual smooth approach to coexistence seen in previous resource competition models.
