Effects of perturbation on community structure and organization in aquatic microcosms

Creator:

Finger, Susan Everett

Abstract:

Aquatic communities consisting of guppies, amphipods, copepods, snails, nematodes, rotifers, protozoans, euglenoid flagellates, and other microorganisms were established in sixteen laboratory microcosms. Guppies were exploited at four different levels (0 percent, 10 percent, 20 percent, and 40 percent of the population biomass) with four communities at each level of exploitation....

Organization and the adaptation of aquatic laboratory ecosystems to resource availability, exploitation, and a toxicant

Creator:

Woltering, Daniel Mark

Abstract:

Organization and the adaptation of aquatic laboratory ecosystems to resource availability, exploitation, and a toxicant were examined in a 34-month study. Sixteen 560-liter microcosms including prey, predator, and competitor populations were employed over a wide range of energy and habitat resource availability and exploitation of the top predator. Chronic exposure...
