  1. POPULATION DYNAMICS AND COMMUNITY ECOLOGY OF ZOOPLANKTON

  2. Range of Food Sizes for Flagellates

  3. Seasonal and Vertical Changes in Grazing

  4. Rotifer Population Dynamics Comparison between simulated and observed population and clonal dynamics. Simulated (A and B) and observed (C–F) population dynamics of total algal cells (open circles, 2 × 106 cells per liter) and rotifers (open diamonds, females per liter) and clonal frequency dynamics of defended clone (UTEX 265, solid squares) and competitive clone (UTEX 396, solid triangles). (C and D) Chemostat results using 80 μM nitrogen medium. (E and F) Chemostat results using 160 μM nitrogen medium. Both chemostats run at a dilution rate, δ, of 0.85. Justin R. Meyer*, Stephen P.

  5. Fig. 3. – Abundance of L. decipiens, B. variabilis and K. tropicain the Schelde estuary in 2002. Stations in the Schelde are denoted according to their distance (in km) to the mouth, at Vlissingen. Stations in the tributaries were called “Ru” for Rupel, “Du” for Durme, “De” for Dender and “Bo” for BovenSchelde. The black line indicates the brackish area of the estuary.

  17. Often see coexistence of several congenerics. Mechanisms which promote their coexistence: • Seasonal separation • Vertical separation • Size differences in prey

Abundance is expressed as percentage of total number of individuals in vertical profile. White bars: day; dark bars: night. Error bars equal twice the standard error of the mean.
