Albufera de València Fish Community: Occurrences, Traits, and Niches (1865–2025)

The Albufera de València in Spain provides the geographic scope for this long-term dataset on its fish community. It compiles species presence-absence records, functional traits, and environmental niche descriptors for fish species from 1865 to 2025. The dataset is structured across three complementary Excel sheets.

Use Cases

• Analyzing temporal trends in species composition and non-native introductions based on presence-absence records.
• Studying functional diversity and trait-based ecology using species-level mean and standard deviation trait values.
• Modeling species distributions or habitat suitability using realized environmental niche descriptors (mean, bounds, and standard deviations).
• Investigating biotic homogenization processes in a Mediterranean coastal lagoon over a 160-year period.

Strengths

• Covers an exceptionally long temporal range of 160 years (1865–2025).
• Integrates three complementary data types: occurrence records, functional traits, and niche descriptors.
• Published under a permissive CC-BY-4.0 license, facilitating reuse.
• Dataset is available on a recognized repository (figshare), indicating a level of curation.

Limitations

• Column names and a precise row count are not provided in the available metadata, limiting initial assessment of structure.
• The dataset's size is given only as a file size (53969), not as a record count.
• Relies on compiled historical records, which may have inconsistent sampling effort or methods over the 160-year period.
