Zebrа mussels аre аn invasive species that has becоme widely established thrоughоut the United States. Figure 1 shows the percent change in the population sizes of selected groups of organisms in the Hudson River since the introduction of zebra mussels. In this study chlorophyll-containing bacteria are considered phytoplankton and all other bacteria are considered bacterioplankton. The bars are labeled along the horizontal axis as follows: Phytoplankton, Native Mussels, Zooplankton, Open Water Fish, Bacterioplankton, Shoreline Bottom Animals, Shoreline Fish. Each bar belongs to one of two categories: Open Water Habitat, or Shoreline Habitat. The vertical axis is labeled Change After Zebra Mussel Invasion, in percent, and the numbers negative 100 through positive 150, in increments of 50, are indicated. Each bar is described as follows. Note that all values are approximate. Phytoplankton. Negative 80 percent, Open Water Habitat. Native Mussels. Negative 75 percent, Open Water Habitat. Zooplankton. Negative 74 percent, Open Water Habitat. Open Water Fish. Negative 26 percent, Open Water Habitat. Bacterioplankton. 48 percent, Open Water Habitat. Shoreline Bottom Animals. 24 percent, Shoreline Habitat. Shoreline Fish. 98 percent, Shoreline Habitat. Figure 1.
