Zooplankton Abundance and Diversity in Columbia River Basin Reservoirs, 2022-2024

Jessica Mitchell's dataset contains code and data for a study comparing zooplankton communities in four Columbia River Basin reservoirs over two years from November 2022 to September 2024. The study collected triplicate zooplankton tows and environmental data bimonthly from two run-of-river and two storage reservoirs. It includes results from statistical analyses like PERMANOVA and NMDS ordination used to assess assemblage patterns.

Use Cases

• Comparing zooplankton diversity and abundance based on reservoir type mentioned in the description
• Modeling zooplankton assemblage structure based on environmental variables like nitrate and conductivity
• Analyzing seasonal variability in freshwater zooplankton communities over a two-year period
• Investigating the relationship between water residence time and zooplankton taxa composition

Strengths

• Data collected bimonthly over a two-year period (November 2022-September 2024)
• Includes environmental parameters like nitrate, phosphate, Secchi depth, and conductivity
• Compares two distinct reservoir types (run-of-river and storage) across four sites

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• The dataset is small at 126.6 KB, indicating limited scope
