Summary
This study presents the first comprehensive trait database for European subterranean spiders, detailing 64 traits for 512 species. This resource facilitates research into subterranean adaptation and biodiversity patterns.
Area of Science:
- Ecology
- Evolutionary Biology
- Biogeography
- Conservation Biology
Background:
- Trait databases are crucial for ecological and evolutionary research but are lacking for many species, particularly those in subterranean habitats.
- Caves and other underground ecosystems harbor unique biodiversity that remains understudied due to accessibility challenges.
Purpose of the Study:
- To compile and present a comprehensive, expert-curated trait database for European subterranean spiders.
- To facilitate future research on subterranean adaptation, biodiversity, and ecological patterns in these unique environments.
Main Methods:
- Updated the checklist of European subterranean spiders, identifying 512 species across 20 families.
- Compiled 64 morphological and ecological traits for each species using literature data and direct measurements.
- Included traits related to subterranean adaptation, habitat preference, dispersal, and feeding strategies.
Main Results:
- The database includes 512 European subterranean spider species, with 192 exclusively found in subterranean habitats.
- 64 distinct traits were recorded for each species, covering morphology and ecology.
- Data were sourced from extensive literature review and direct specimen analysis.
Conclusions:
- The freely available trait database provides a valuable resource for studying subterranean ecosystems.
- Enables quantitative analysis of functional traits related to subterranean adaptation and functional diversity patterns.
- Opens new avenues for research in subterranean ecology and conservation biology.
