Two-Way ANOVA Results for Rocky Reef Benthic Communities in Yucatan

Ileana Ortegón-Aznar's dataset contains statistical results from a two-way ANOVA analysis of benthic communities on rocky reefs. The data, stored in an XLS file, supports ecological research on the Mexican Atlantic coast. It quantifies relationships between macroalgal abundance, long sediment-laden algal turf, and environmental factors like depth and sediment type.

Use Cases

• Perform two-way ANOVA to test the effect of sediment type and depth on macroalgal abundance.
• Analyze the strong negative correlation (r = -0.754) between macroalgal abundance and long sediment-laden algal turf (LSAT).
• Model benthic community composition using factors like topographic complexity and rugosity indices from bathymetric surveys.
• Investigate competitive dynamics between macroalgae (64% cover) and sessile invertebrates like sponges.

Strengths

• Includes statistically significant findings, such as a strong negative correlation (r = -0.754, P < 0.0001) between key benthic components.
• Provides ecological data from four distinct rocky reef sites along the Yucatan Peninsula, enabling comparative analysis.
• Focuses on a previously understudied region, representing the first report of rocky reefs on the Mexican Atlantic coast.

Limitations

• The dataset is very small (5.5 KB), indicating limited scope and likely a summary of results rather than raw observational data.
• Specific sample sizes, row counts, and column definitions for the ANOVA are not provided, limiting reproducibility.
• Geographic coverage is restricted to four sites on the Yucatan Peninsula, which may not represent broader regional dynamics.
