Fish Beta Diversity Drivers in Atlantic Forest Temporary Habitats

1,545 fish individuals from 20 species were sampled across 36 temporary pools and 36 roadside ditches in the Atlantic Forest during 2024. The dataset supports analysis of community composition differences between habitat types and rainfall periods. It examines beta diversity components against local environmental and spatial predictors.

Use Cases

• Analyze fish community composition differences between the 36 temporary pools and 36 roadside ditches habitat types.
• Test associations between beta diversity components and predictors like habitat volume, pH, and distance to nearest stream.
• Model the influence of rainfall periods (wet/dry) on spatial beta diversity and turnover dynamics.
• Investigate species accumulation patterns (nestedness) correlated with differences in habitat volume during the dry period.

Strengths

• Sampling covers 72 distinct sites (36 pools and 36 ditches), providing spatial breadth.
• Records 1,545 individual fish observations from 20 identified species.
• Data includes temporal dimension with sampling across wet and dry rainfall periods in 2024.

Limitations

• Dataset scope is limited to a single year (2024), preventing analysis of long-term trends.
• Small file size (24.5 KB) indicates the data is likely summary or processed results, not raw survey records.
• Geographic focus is restricted to the Atlantic Forest region of Brazil.
