Zooplankton Species & abundance

Zooplankton Abundance

Plankton abundance is an important core variable because plankton react directly to their environment. Depending on environmental conditions, zooplankton will either survive and reproduce, get consumed by other marine organisms, or die and decompose.

Each of these potential outcomes constitute a valuable contribution to the marine environment. Abundance indices are important for ascertaining species diversity, which are necessary for marine conservation efforts.

Zooplankton Species

Zooplankton species are indicative of oceanographic parameters. For example, cold water copepods Neocalanus plumchrus, Calanus marshallae, and Pseudocalanus mimus are found in Alaskan waters. Monitoring species over time and space provides valuable information pertaining to the study of ecosystem dynamics, climate variability and human impact.
