  1. The LEDA Traitbase a database on life-history plant traits Irma Knevel1,2 Renée Bekker2 Presented by Ingolf Kühn 3 1 Landscape Ecology Group, University of Oldenburg (DE) 2 Community and Conservation Ecology Group, University of Groningen (NL) 3 Department of Community Ecology - Centre for Environmental Research Leipzig-Halle (UFZ) (DE) - Leda and the swan - EVR1-CT-2002- 40022 LEDA

  2. Fact Changing land use, pollution, eutrophication, fragmentation EssentialUnderstand and predict the consequences Problem Information scattered and unavailable SolutionLEDA TRAITBASE Why a life-history database of plant traits? user Environmental agencies - Land use managers - Policy makers - Researchers

  3. What is the LEDA Traitbase? Online ecological data and information management: Ecoinformatics LEDA Traitbase • species-trait matrix for ~ 3000 species • with each record referenced • based on firm data standards and protocols • designed as a web-based database • that operates with a user-friendly interface • where users will be able to download (selected) traits

  4. Area selected: NW Europe

  5. What can you expect of the LEDA Traitbase? Objectives: 1. To predict plant biodiversity and plant mobility in a changing landscape 2. To pool trans-national expertise on: Functional significance of traits Trait classification Trait measurement tool Planning Restoration & conservation Applied research  Brook restoration Drentse Aa (NL)

  6. BiolFlor Seed bank database LEDA Traitbase construction Species-trait matrix: ~ 3000 NW European species >20 traits of key features persistence, regeneration & dispersability • Filling of the matrix: • Collation of existing databases • Literature compilation • Unpublished data Gaps: Additional measurements  Firm protocols & standards Deduction  Extensive measurements of simple morphological traits E.g. Seed persistence predicted from seed size and shape (Thompson et al. 1997, validation e.g. Funes et al. 1999)

  7. LEDA traits: Persistence & Regeneration 1. Persistence 2. Regeneration • canopy height • plant growth form (Raunkiaer) • leaf distribution (along the stem) • clonal growth organs (CGO) • persistence mother-daughter connection • leaf mass • leaf size • specific leaf area (SLA) • tissue density • shoot growth form • lateral spread/year • plant life span • age of first flowering • seed number per shoot • seed shape • seed weight • seed size • seed longevity (soil seed bank) 

  8. LEDA traits: Dispersability 3. Dispersability • morphology of dispersal unit (anemochory) • releasing height • terminal velocity • attachment capacity dispersal unit (epizoochory) • survival capacity of digestive tract (endozoochory) • buoyancy (hydrochory)

  9. Input by the consortium Adherent Bulk Data available Con- to LEDA upload amongst LEDA Web-based query verter form partners standards and output form Researchers Data from Data publications input Conversion LEDA Missing data form into database measured by format LEDA partners Input scientific community Tutorials Check and Data-mining tools Data generated Data Bulk by non-LEDA input upload Stake holders approval partners form form use managers Land Policy consultants LEB LEB: 10 LEDA Traitbase partners 5 External expert scientists 1 Member of the EEA (EUNIS) Traitbase construction: Data flow chart

  10. Traitbase: Architectural overview & principles Web Query Interface Web Data Input Web Reporting Tool Web Tool for Data-Mining Web Application Container Database System Data Importing Tools • Relational schema: About 150 tables • Database Management System: Oracle 9i • Web application container: Apache Tomcat 4.1/5.0 • Extensibility: Addition of traits does not require major changes • Openness: Arbitrary SQL queries in addition to standard queries • Reproducibility: Results of online-queries are citable due to versioning

  11. Example: Online input form

  12. LEDA Traitbase: Status April 2004 Persistence Regeneration Dispersability Average data available = 42% x = data collection finished
