Why a life-history database of plant traits?
user
Fact Changing land use, pollution, eutrophication, fragmentation
Essential Understand and predict the consequences
Problem Information scattered and unavailable
Solution LEDA TRAITBASE
Environmental agencies - Land use managers - Policy makers - Researchers
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
What is the LEDA Traitbase?
Online ecological data and information management: Ecoinformatics
Area selected: NW Europe
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
Planning
Restoration & conservation
Applied research
tool
Objectives:
Brook restoration Drentse Aa (NL)
What can you expect of the LEDA Traitbase?
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Filling of the matrix: Collation of existing databases Literature compilation Unpublished data

Additional measurements Firm protocols & standards
Deduction Extensive measurements of simple morphological traits
(Thompson et al. 1997, validation e.g. Funes et al. 1999)
E.g. Seed persistence predicted from seed size and shape
Gaps:
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
1. Persistence
plant life span age of first flowering seed number per shoot seed shape seed weight seed size seed longevity (soil seed bank)
2. Regeneration
LEDA traits: Persistence & Regeneration
morphology of dispersal unit (anemochory) releasing height terminal velocity attachment capacity dispersal unit (epizoochory) survival capacity of digestive tract (endozoochory) buoyancy (hydrochory)
3. Dispersability
LEDA traits: Dispersability

Traitbase construction: Data flow chart
Traitbase: Architectural overview & principles
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
