Summary
This study presents a global freshwater fish species database for 3119 drainage basins, crucial for understanding biodiversity patterns and conservation in threatened aquatic ecosystems.
Area of Science:
- Ecology and evolutionary biology
- Aquatic biodiversity research
Background:
- Freshwater ecosystems harbor a high proportion of global fish diversity.
- These habitats are critically threatened by global change.
- Global-scale ecological and evolutionary studies require comprehensive species distribution data.
Purpose of the Study:
- To compile a comprehensive global database of freshwater fish species distribution.
- To support macroecological, macroevolutionary, biogeographical, and conservation research.
Main Methods:
- Compiled species lists for 3119 drainage basins covering over 80% of Earth's surface.
- Included 14953 freshwater fish species (native and non-native).
- Data sourced from 1436 publications, books, grey literature, and web sources.
Main Results:
- A database of freshwater fish species distribution across 3119 drainage basins.
- The database covers more than 80% of the Earth's surface.
- Incorporates data on 14953 fish species.
Conclusions:
- The database is a valuable resource for macroecology, macroevolution, biogeography, and conservation studies.
- Facilitates global-scale analyses of freshwater fish diversity and threats.
- Enables integrated studies combining distribution with biological, ecological, and evolutionary data.
